[Objective] To gain more insight into the presentation,diagnosis of Bertolotti's syndrome and to investigate the indications,the procedure and the early clinical results of minimally invasive transverse process plasty.[Methods]Thirteen cases(Santavirta Type I)with Bertolotti's syndrome underwent minimally invasive transverse process plasty under MED X-tube(Medtronic Sofamor)from Apr.2006 to Dec.2008.The Visual Analogue Scale(VAS),Modified Oswestry Disability Index(ODI)score and subjective sensation of patients were recorded to evaluate the function.[Results]The operation blood loss was from 120 ml to 800 ml and operative time was from 60 to 280 minutes,average 115minutes.There was no severe complication.Nine cases were followed up for 10 to18 months,average 13.6 months.The VAS decreased from(6.7?2.2)before operation to(2.2?0.7)one week after operation and(2.8?0.9)three months after operation.ODI score decreased from(27.8?3.6)before operation to(5.9?2.2)three months after operation.The results were excellent in 10 case and good in 3 cases.[Conclusion]Minimally invasive transverse process plasty is an effective method for Bertolotti's syndrome,especially for Santavirta type I.It shows less blood loss and injury and deserves to be spreaded.Disectomy is recommended in one stage if the patient is complicated with disc herniation.

Objective To investigate the long-term effects of intrauterine mild hyperglycemia exposure and postnatal high fat diet on the body weight and metabolism of offspring through a pregnant rat model of intrauterine mild hyperglycemia.Methods Twenty-one pregnant Wistar rats were randomly divided into intrauterine hyperglycemia group and control group.Twenty percent streptozotocin (STZ,25 mg/kg)was given to rats of intrauterine hyperglycemia group by a single intraperitoneal injection to induce intrauterine mild hyperglycemia; control group rats received an equal volume of citric acid-sodium citrate buffer.Off springs were divided into 4 groups:exposed to intrauterine hyperglycemia and fed with normal diet group(group DN)or high fat diet group (group DF) ; exposed to intrauterine euglycemia and fed with normal diet group(group CN)or high fat diet group(group CF).The blood glucose levels of pregnant rats in two groups and body weights of offsprings in four groups were recorded.At the age of 28 weeks,the mesenteric fat amount,epididymal amount,perirenal fat amount,total triglyceride (TG)and high density 1 ipoprotein-cholestrol(HDL-C) were measured in all four groups.Results (1) The average blood glucose level of intrauterine hyperglycemia group[(16.6 ± 3.4) mmol/L] was significantly higher than that of the control group [(5.8 ± 1.1) mmol/L,P ＜ 0.01].(2) On the birth day,3 weeks and 4 weeks,the body weight of group DN [(7.4 ± 0.6),(44.1 ± 5.9),(79.6 ± 7.4) g] and group DF [(7.4 ± 0.2),(43.9 ±6.9),(76.1 ± 5.8) g] were remarkably increased compared with group CN [(6.6 ± 0.5),(35.6 ± 4.4),(71.5±6.8) g,P＜0.05]; but the body weight in group CF [(6.7 ±0.5),(33.0 ±6.5),(66.1 ±10.2) g] had no statistical difference compared with group CN(P ＞ 0.05).(3)From then on,the bodyweights of the offsprings in four groups presented an increasing trend,but there was no statistical difference until 28 weeks(P ＞0.05).(4) The perirenal fat amount of group DN,group CF and group DF [(13.8 ±3.3),(14.3 ± 3.2),(18.4 ± 1.3) g] were remarkably increased compared with group CN [(9.7 ± 3.5) g,P ＜ 0.05] ; the epididymal fat amount of group CF and group DF were also significantly increased compared to group CN(P ＜ 0.05) ; the mesenteric fat amount in four groups had no statistical difference (P ＞ 0.05).(5) The TG level of group DN,group CF and group DF[(0.52 ±0.14),(0.52 ±0.09),(0.54 ±0.17)mmol/L] were significantly higher compared to group CN [(0.41 ± 0.09) mmol/L,P ＜ 0.05],but there was no statistical difference within the first three groups (P ＞ 0.05) ; the HDL-C level in four groups had no statistical difference(P ＞ 0.05).Conclusions In intrauterine mild hyperglycemia environment,there were some evidently metabolic changes observed in the offspring,including body weight increasing on birth day and early postnatal period,visceral fat amount increasing and lipid metabolism disorders,which could be aggravated by postnatal high fat diet.

Objective To evaluate the actual displacement of a femoral neck fracture following close reduction under the C-arm X-ray perspective.Methods From June, 2006 to June, 2009, we managed 12 patients with femoral neck fracture by open reduction and internal fixation.They were 8 males and 4 females, aged from 23 to 65 (average, 42.3) years old.We tried close reduction of their fractures under the C-arm X-ray perspective before a temporary fixation.Next we performed open reduction, readjusted the fracture ends, and placed internal fixation.The actual displacement of the fracture measured after open reduction was carefully compared with the close reduction under the X-ray perspective.Results A substantial displacement was found after open reduction in 7 patients who had achieved anatomic reduction under the X-ray perspective.In the other 5 patients who presented with a slight displacement after close reduction under X-ray perspective, the actual displacements were larger than the X-ray observations but completely reduced after open reduction.The actual measurements after open reduction were significantly larger (3.21 ± 0.96 mm on average) in the anteroposterior displacement ( t = 11.540, P = 0.000), but insignificantly larger (0.58 ±0.93 mm on average) in the superior-inferior displacement ( t = 2.184, P = 0.346) than those after close reduction.Conclusions In general, anatomic reduction can not be achieved for a femoral neck fracture under the C-arm X-ray perspective.Consequently, open reduction may be better than close reduction in the treatment of femoral neck fracture in that improper reduction can block blood supply to the femoral neck and dissection of the capsula articularis coxae can improve blood supply as well as help decompression.

Objective To investgate the efficiency of autologous fat grafting for breast augmentation by improving low negative pressure mechanical liposuction.Methods A total of 37 cases of breast augmentation by autologous fat grafting were reviewed;group A included 19 cases of improved low pressure mechanical liposuction,and group B had 18 cases of traditional syringe liposuction.Respectively,the operating time of harvesting 800 ml fat granules (standing 30 mins) were recorded,and operative blood loss by testing the red blood cell count of lower mixed liquid was calculated,and then growth increment of nipple chest circumference of 6 months after operation were measured.The valid follow-up satisfaction scores were counted.Results The operating time of harvesting 800 ml fat granules were (53.32±4.73) mins for group A and (80.78±7.86) mins for group B,respectively;operative blood loss was (81.58±10.80) ml for group A and (72.94±13.45) ml for group B;All P＜0.05.The valid follow-up satisfaction scores were 78.9％ (15/19) for group A and 77.7％ (14/19) for group B.Growth increment of nipple chest circumference of 6 months after operation between groups were no statistical significance (P＞0.05);but the remarkable difference within both groups in internal comparison existed between 6 months and 1 month after operation (P＜0.05),also between 3 months and 1 month after operation (P＜0.05).Conclusions Improved low pressure mechanical liposuction in breast augmentation by autologous fat grafting is able to enhance the surgical efficiency evidently and shorten the operating time significantly.

Recent studies have found that autophagy was not only involved both in the occurrence and development of viral myocarditis (VMC),but also,it plays a key role in anti-viral infections by degradating the viral components,presenting viral antigens and activating the immune response.Meanwhile,the virus can also escape the protective antiviral activity and maintain their own survival and replication by inducing the autophagy of the host cells,becoming the accelerator of the viral infection.The interaction of the virus and the host cell autophagy in VMC is a complex process.Its detailed pathogenesis has yet to be further explored.
