ObjectiveTo analyze risk and therapy strategy of tiny gallbladder stones during laparoscopic cholecystectomy (LC).MethodThe clinical data of 932 patients with tiny gallbladder stones performed LC from September 2013 to July 2014 were analyzed retrospectively.ResultsThe LC was successful in all the patients. The gallbladders were ruptured in 86 (9.23%) patients during operation. Following up 1-3 months, there were 26 patients with right upper abdominal pain and with residual small stones in the abdominal cavity, 57 patients without uncomfortable symptoms and without residual gallstone, 2 cases complicated with lesser abdominal abscess, 1 case complicated with incision infection. The incisional hernia and acute pancreatitis were not found.ConclusionsThe gallbladder with full of tiny stones performed LC easily leads to choledocholithiasis or acute pancreatitis. If intraoperative gallbladder rupture, the tiny stones might be residual in the peritoneal cavity and lead to abdominal infection or abscess, and incision infection or trocar site hernia. Specific operation could effectively avoid adverse complications.
OBJECTIVE: To investigate the effect of soft tissue repairing at different times on the union of type III b tibial fracture. METHODS: From January 1987 to January 1999, seventy-six type III b tibial fractures were divided into 3 groups: early group(0 to 7 days), subacute group(8 to 30 days), late group(more than 30 days) according to the time of soft tissue repairing. The morbidity rates of complications such as infection, nonunion as well as the time to union were compared respectively. RESULTS: Followed up for 10 to 36 months (averaged 24 months), the infection and nonunion rates of early group were lower than that of subacute and late groups(P lt; 0.01), the average time of fracture union of early group was less than that of subacute and late groups. CONCLUSION: Early soft tissue repairing can decrease the complications and the time to union of Type III b tibial fracture obviously. The time of "early" should be limited in one week and as soon as possible.

Methods The pathologic samples of six patients with gynandroblastoma from March 2004 to March 2008 were observed and analyzed. Immuohistochemistry staining was performed by SP method using antibodies of α-inhibin,CD99,Vimentin,Calretinin,CK,EMA. Results The main clinical features included menstrual disorders, amenorrhea, and postmenopausal bleeding. The tumor was composed of ranulose cells and Sertoli cells, both of which were well differentiated. Strongly positive expression of α-inhibin and vimentin was found in all the patients, while CD99 (+) was in three, calretinin (+) was in five, and CK (+) of Sertoli cells was in two. Four patients were followed up for 14-60 months and all were tumor free. Conclusion The main clinical features of gynandroblastoma are estrogenic or androgenic manifestations. Nearly all the patients are diagnosed in stage 1 and have a good prognosis. Patients with gynandroblastoma should be followed up for a long period.
【Abstract】 Objective To explore the clinical application and outcomes of preoperative second measurement of three-dimensional (3-D) CT reconstruction data for scoliosis orthopedic surgery. Methods Between August 2006 and March 2008, 11 patients with severe rigid scoliosis received surgery treatment, including 4 males and 7 females with an average age of 17.2 years (range, 15-19 years). Preoperative second measurement of 3-D CT reconstruction data was conducted to guide the surgery， including the angle and width of pedicle, the entry point, and the choice of screws whose lengths and diameters were suitable. A total of 197 pedicle screws were implanted. The operation time， blood loss， postoperative nerve function，and Cobb’s angles at sagittal and coronal view were all recorded， and the postoperative CT scan was performed to assess the accuracy of pedicle screw insertion according to Andrew classification. Results Pedicle screws were implanted within 1-11 minutes (mean, 5.8 minutes), and the blood loss was 450-2 300 mL (mean, 1 520 mL). The postoperative X-ray films showed the correction rates of Cobb’s angle were 68.5% in coronal view and 55.5% in sagittal view. The accuracy of pedicle screw insertion was rated as grade I in 77 screws (39.1%)，grade II in 116 screws (58.9%)， and grade III in 4 screws (2.0%) according to postoperative CT scan. All 11 cases were followed up 14 months to 2 years without any complications. Conclusion Preoperative second measurement of 3-D CT reconstruction data can make the surgery process easy and accurate in treatment of severe scoliosis.

In addition to the typical respiratory symptoms, COVID-19 patients present with clinical manifestations of cardiovascular system damage, and they are at higher risk of intensive care or mortality. The mechanism of COVID-19's impact on the cardiovascular system is still unclear, therefore we need to pay close attention to it. Based on the existing research, this paper focused on the concurrent characteristics of the cardiovascular system diseases, summarized the possible mechanisms of cardiovascular system damage, including the coronavirus invaders directly into cardiomyocytes and its conduction system, with complications or accompanying conditions such as cytokine storm, imbalance of oxygen supply and demand, drug influence, stress and other damage to cardiovascular system. Meanwhile, current clinical manifestations and treatment methods of COVID-19 were summarized.
Objective?To investigate the surgical method and clinical efficacy of repairing whole-hand destructive injury or hand degloving injury with the transplant of pedis compound free flap.?Methods?From February 2003 to June 2008, 21 patients with whole-hand destructive injury or hand degloving injury were treated, including 15 males and 6 females aged 18-45 years old (average 25 years old). The injury was caused by punching machine crush in 10 cases, roller crush in 7 cases, and imprinter crush in 4 cases. The time between injury and operation was 1-9 hours. Eleven cases had the skin-degloving injury of the whole hand, while the other 10 cases had the proximal palm injury combined with dorsal or palmar skin and soft tissue defect. After debridement, the size of wound was 9 cm × 7 cm - 15 cm × 10 cm in the dorsal aspect and 10 cm × 7 cm -16 cm × 10 cm in the palmar aspect. The defect was repaired by the thumbnail flap of dorsalis pedis flap and the second toenail flap of dorsalis pedis flap in 5 cases, the thumbnail flap of dorsalis pedis flap and the second toe with dorsalis pedis flap in 4 cases, and bilateral second toe with dorsalis pedis flap in 12 cases. The flap area harvested during operation ranged from 6 cm × 5 cm to 16 cm × 11 cm. Three fingers were constructed in 2 cases and two fingers in 19 cases. Distal interphalangeal joint toe amputation was conducted in the thumbnail flap donor site, metatarsophalangeal joint toe amputation was performed in the second toenail flap donor site, and full-thickness skin grafting was conducted in the abdomen.?Results?At 7 days after operation, the index finger in 1 case repaired by the second toenail flap suffered from necrosis and received amputation, 1 case suffered from partial necrosis of distal dorsalis pedis flap and recovered after dressing change, and the rest 42 tissue flaps survived. Forty-three out of 44 reconstructed fingers survived. All the wounds healed by first intention. At 2 weeks after operation, 2 cases had partial necrosis of the donor site flap and underwent secondary skin grafting after dressing change, the rest skin grafts survived, and all the wounds healed by first intention. Nineteen cases were followed up for 6-36 months (average 11 months). The flaps of palm and dorsum of hand showed no swelling, the reconstructed fingers had a satisfactory appearance and performed such functions as grabbing, grasping, and nipping. The sensory of the flaps and the reconstructed fingers recovered to S2-S4 grade. The donor site on the dorsum of the foot had no obvious scar contracture, without obvious influence on walking.?Conclusion?For the whole-hand destructive injury or hand degloving injury, the method of transplanting pedis compound free flap can repair the defect in the hand and reconstruct the function of the injured hand partially. It is an effective treatment method.
