OBJECTIVETo explore the reason, key diagnosic point and therapeutic method of the incisions fat colliquation or infections at early stage after operation of lumbar disc herniation.

METHODSFrom July 2007 to May 2012, clinical data of 11 patients with incision fat liquefaction or early infection after lumbar discectomy were retrospectively analyzed. There were 5 males and 6 females with an average age of 43.1 years, and the mean time of incisions fat colliquation or infection was 5 days and a half after operation. The main clinical features included local wound pain aggravating, fervescence, fresh seepage in the wound, and blood inflammatory index increased, etc. The wound could heal at the first treatment stage or not was an evaluation standard of curative effect.

RESULTSAll patients were followed up with an average period of 21 months. The wounds of 10 cases healed at the first stage without recurrence and complications. In 1 case infected by staphylococcus aureus, distal part of the wound present local red, swelling and with wave motion at 2 months after operation, staphylococcus aureus infection was confirmed after puncture and bacterial culture, and 1 thrum was found after local incision. The wound healed after change dressings for 1 week, without recurrence after followed up for 13 months.

CONCLUSIONPreventing the risk factors before operation, minimizing invasive technique during operation reasonable antibiotics application for the lumbar operation reguiring placement objects, and correctly handling with wound after operation could prevent and reduce the incidence of incisions fat liquefaction or infection after operation of lumbar disc herniation. For incision fat liquefaction or infection, early diagnosis, debridement, VSD negative pressure irrigation and drainage, to choosing sensitive antibiotics according to the results of drug sensitivity, may contribute to wound early healing and decrease complication.

Objective To evaluate the relationship between serum matrix metalloproteinase-9(MMP-9), white blood cell(WBC)count and type 2 diabetes mellitus with macroangiopathy and to investigate the mechanism of the protective effects of rusiglitazone(RSG)on blood vessel.Methods Serum MMP-9 was determined by ELISA in 30 normal controls and 80 type 2 diabetic patients(including 40 cases with macroangiopathy and 40 without maeroangiopathy).WBC count and other clinical parameters were also determined.32 type 2 diabetic patients received RSG(4rag qd)for 12 weeks.All parameters were determined after 4 weeks(17 patients)and after 12 weeks(all patients)to observe the changes in MMP-9,WBC and other parameters.Results In the diabetic patients,serum MMP-9 and WBC were markedly higher as compared with normal controls;and MMP-9 and WBC in patients with macroangiopathy[579(440-949)?g/L,(7.51?1.47)?10~9/L]were higher than those [324(275-423)?g/L,(6.22?0.79)?10~9/L]in the cases without macroangiopathy(P

ObjectiveTo evaluate the clinical effectiveness of posterolateral autograft bone graft fusion transpedicular screw system internal fixation and anterior debridement in the treatment of dorsal and lumber spinal tuberculosis. MethodsFrom March 1996 to July 2000,posterolateral autograft bone graft fusion transpedicular screw system internal fixation and anterior debridement procedures were used in 62 patients suffering from dorsal and lumber spinal tuberculosis in our department,48 of them were involved in a longitudinal study follow-up for a mean of 3.6(1.5-5.5)years postoperatively. ResultsAll patients showed successful posterolateral bone graft fusion. Among 38 cases of Pott's paraplegia, 30 were completely recovered,5 were partly recovered,the rate of recovery was 92.1%. The average immediate postoperative correction of kyphosis angle was 29.1°,the average loss of correction was only 3.2°at final follow-up.ConclusionsPosterolateral autograft bone graft fusion transpedicular screw system internal fixation and anterior debridement procedure were found helpful in strengthening the stability of the spine in dorsal and lumber spinal tuberculosis, providing successful interbody fusion and recovery of Pott's paraplegia, correcting the kyphosis, and preventing progression of kyphosis.

Objective To investigate the inhibitory effect of favipiravir (T-705) on canine distemper virus (CDV) replication in Vero cells and DH82 cells.Methods The growth curves of CDV-11 strains from canine and CDV-3 strains from mink in Vero cells and DH82 cells were determined with indirect immunofluorescence assay and 50％ endpoint titration.The viability of Vero and DH82 cells was determined using the Cell Counting Kit-8.CDV inhibition at different concentrations of T-705 at different time points was measured .Results Cytotoxicity data showed that there was a moderate decline of viability in Vero cells after T-705 treatment, but no apparent cytotoxicity in DH 82 cells.T-705 significantly inhibited the replication of CDV-3 and CDV-11 in both Vero cells and DH82 cells in the test range of 2.441-1250 μg/ml. T-705 exhibited effective and stable antiviral activity when given at different time points post virus challenge .Conclusion Our results demonstrate that T-705 has effective antiviral activity and may be a promising anti-CDV drug candidate .

OBJECTIVETo investigate the influence of Rehmannia glutinosa oligosaccharides (ROS) on the proliferation of 3T3-L1 adipocytes and insulin resistance.

METHOD3T3-L1 preadipocytes were cultured, the proliferation of 3T3-L1 preadipocytes was detected by MTT method. Insulin resistant 3T3-L1 adipocytes cell model was induced by dexamethasone and the change of glucose concentration in cell culture was determined after ROS treatment.

RESULTIn the high glucose DMEM culture media, MTT method showed that the absorbance at 570nm of 3T3-L1 preadipocytes was increased and that of 3T3-L1 adipocytes was decreased. ROS significantly increased glucose consumption in 3T3-L1 preadipocytes and adipocytes culture in a concentration-dependent manner. ROS improved the sensitivity of 3T3-L1 adipocytes to insulin.

CONCLUSIONROS can promote the proliferation of 3T3-L1 preadipocytes, inhibite the proliferation of 3T3-L1 adipocytes, and also, significantly improve insulin resistance induced by dexamethasone.

OBJECTIVETo explore the clinical symptom and effect of arthroscopic treatment of symptomatic anterior cruciate ligament (ACL) cysts of the knee.

METHODSClinical data from 12 symptomatic ACL cysts patients from January 2005 to December 2010 were retrospectively analyzed,including 8 males and 4 females,with an average age of (33.7±9.5) years old (ranged, 19 to 53 years old). The locations were the left knee in 5 cases and the right knee in 7 cases. The disease duration ranged from 3 to 48 months,with a mean of (15.8±13.2) months. All cysts were arthroscopically resected. Range of motion was measured preoperatively and postoperatively, and Lysholm scoring system was used to evaluate the knee function.

RESULTSAll the incisions healed by first intention, and no complications occurred. Twelve patients were followed up for an average of (32.3±6.6) months(ranged, 24 to 48 months). The symptoms of arthralgia,swelling and interlocking of the affected knees disappeared. There was no recurrence during the follow-up. There were significant differences in the range of motion and Lysholm score between pre-operation and post-operation.

CONCLUSIONArthroscopic surgery, showing its advantages of minimal invasion and rapid recovery,is an effective measure in the treatment of ACL cysts.

The purpose of this study was to investigate the existence and extent of cognitive impairment in adult diabetes mellitus (DM) patients with episodes of recurrent severe hypoglycemia,by using meta-analysis to synthesize data across studies.PubMed,EMBASE and Cochrane library search engines were used to identify studies on cognitive performance in DM patients with recurrent severe hypoglycemia.Random-effects meta-analysis was performed on seven eligible studies using an inverse-variance method.Effect sizes,which are the standardized differences between the experimental group and the control group,were calculated.Of the 853 studies,7 studies met the inclusion criteria.Compared with control subjects,the adult DM patients with episodes of recurrent severe hypoglycemia demonstrated a significantly lowered performance on memory in both types of DM patients,and poor performance of processing speed in type 2 DM patients.There was no significant difference between adult DM patients with and those without severe hypoglycemia in other cognitive domains such as general intelligence,executive function,processing speed and psychomotor efficiency.Our results seem to confirm the hypothesis that cognitive dysfunction is characterized by worse memory and processing speed in adult DM patients with a history of recurrent severe hypoglycemia,whereas general intelligence,executive function,and psychomotor efficiency are spared.
