In the study of T2DM(n=30),IGR(n=26) and NGT(n=30) cases in Guangxi Province,T2DM had higher resistin and PAI-1 levels than did the groups of IGR and NGT(P<0.05).IGR had higher levels of PAI-1 and leptin than NGT(P<0.05).Leptin level of T2DM was higher than that of NGT(P<0.05).Insulin resistance index was positively correlated with leptin,TG and PAI-1 levels(P<0.05).

Femoral head necrosis and nonunion is a common complication after surgery of femoral neck fracture.Recently,femoral neck shortening have caused attentions which can impact the function of hip.Incidence,mearsurement,influence factor,prevention and treatment of femoral neck shortening have been retrospective reviewed.Amount of femoral neck shortening with sliding compression system is significantly more than length of stability system,which is result from its own mechanism.However,effcacy of length of stability system still need a large scale of sample.It uses radiography to diagnose shortening.The present measurement methods include displacement of femoral head,xyz-axis measurement,the length of exposed screw,the collapse of femoral head.However,position,the angle of screen and the defect of the method would increase deviation.A measurement with simple,wide application and accuracy need to continue to explore.Apart from patients' condition,shortening also affected by the pattern and quality of surgery.Overall,older women,displacement fracture,unsatisfactory reduction will increase the risk and shrinkage of shortening.In addition,the pattern of the internal fixation becomes the research focus in the field of orthopedic clinical research.Including the transformation of sliding compression system device and design of novel device.How to combine them together organically could be a future development direction.Meanwhile,there are still in exploratory stage to decide whether biological combined with internal fixation can prevent shortening.Intertrochanteric osteotomy can achieve union and correct the limblength discrepancy,However,it did not restore the length of femoral neck.So,it is unknown that whether the method can solve the slight shortening which have impacted the hip function.

Objective To establish a model, fetal rat brain damage made by lipopolysaccharide (LPS)-induced intrauterine infection and explore content change and significance of malondialdehyde(MDA),myeloperoxidase(MPO),intracellular free calcium in the development of fetal brain damage.Methods Twenty-eight pregnant rats were injected with LPS(500 ?g/kg)on gestation d20 intraperitoneally in experimental group rats;the same volume of normal saline was injected to 28 rats as control group;there were 8 pregnant rats as blank control rat. Fetal brain water,MDA,MPO,Ca~(2+) contents were measured, fetal brain,placenta for pathological check after injection 2,6,12,24 hours,respectively.Results Brain water,MDA,MPO contents of LPS group were higher than those of controls at 2 h,and Ca~(2+) content of LPS group was higher than that of controls at 6 h,they were continued to be on high level until 24 h.There were histopathological inflammation changes of placenta, edema,inflammation in fetal brain at 6 h ,degeneration and necrosis of nerve cell at 12 h.Conclusions Fetal rat brain damage is made by LPS-induced intrauterine infection.MDA,MPO,Ca~(2+) content increasing in fetal brain tissue that indicates there is lipid peroxidation damage in fetal rat brain damage due to intrauterine infection; damage of free radical,persistent activation of polymorphonuclear,calcium overlord are mechanisms of fetal brain damage .

BACKGROUND:To date, there are few domestic reports about the influence of bone marrow mesenchymal stem cel s on T cel s proliferation in patients with aplastic anemia. And no study addresses the topic that if bone marrow mesenchymal stem cel s achieve immune regulation in aplastic anemia patients through inhibiting T cel s proliferation.
OBJECTIVE:To explore the effects of human bone marrow mesenchymal stem cel s on T cel s immune regulation in patients with aplastic anemia.
METHODS:Human bone marrow mesenchymal stem cel s were isolated, cultured and subcultivated in vitro. The morphological appearance of bone marrow mesenchymal stem cel s was observed and surface markers were measured by flow cyometry. The bone marrow mesenchymal stem cel s were co-cultured with T cel s extracted from peripheral blood of healthy volunteers and aplastic anemia patients for 7 days. The expressions of interferon-γ, interleukin-4 and interleukin-10 in the supernatants were detected with enzyme linked immunosorbent assay.
RESULTS AND CONCLUSION:The levels of interleukin-2 and interferon-γin the supernatant of aplastic anemia patients were significantly higher (P<0.05), while levels of interleukin-4 and interleukin-10 were significantly lower than that in healthy controls (P<0.05). Bone marrow mesenchymal stem cel s suppressed the elevated levels of interleukin-2 and interferon-γ, and enhanced the decreased levels of interleukin-4 and interleukin-10, thus regulating the immune dysfunction of aplastic anemia patients.

Objective To discuss the safety and efficacy of using ExoSealTM vascular closure device to obtain rapid hemostasis of puncture site in interventional procedure via retrograde femoral artery access.Methods The clinical data of 124 patients,who were admitted to authors' hospital during the period from March 2016 to April 2016 to receive interventional procedure via retrograde femoral artery access,were retrospectively analyzed.During the performance of intervention,ExoSealTM vascular closure device (ExoSealTM group,n=52) or manual compression (MC group,n=72) was employed to make femoral artery puncture point hemostasis.The time spent for hemostasis,the manual compression time,the limb immobilization time,the amount of blood loss during compression process,and the procedure-related complications were recorded and the results were compared between the two groups.Results Technical success rate in ExoSealTM group was 98.1％(51/52).In ExoSealTM group and MC group,the time spent for hemostasis was (0.28±0.08) min and (5.83±1.46) min respectively,the manual compression time was (2.65 ±0.57) min and (7.70± 1.88) min respectively,the limb immobilization time was (2.72±0.43) h and (6.15±0.69) h respectively;all the differences between the two groups were statistically significant (P＜0.01).In ExoSealTM group subcutaneous hemotoma occurred in one patient,while in MC group subcutaneous hemotoma occurred in 3 patients and pseudoaneurysm in one patient;the complication rates were 1.92％ (1/52) and 5.56％ (4/72) respectively,but the difference was not statistically significant (P＞0.05).In MC group the amount of blood loss during compression process was (1.11±0.86) ml,which was remarkably less than (7.83±2.08) ml in ExoSealTM group,the difference between the two groups was statistically significant (P＜0.01).Conclusion For hemostasis of puncture site in interventional management via retrograde femoral artery access,the use of ExoSealTM vascular closure device is safe and effective.

To study the effects of alkaloids from Coptidis Rhizoma on low-density lipoprotein receptor (LDLR) mRNA expression and antihyperlipedemic levels. The LDLR mRNA expression were detected by real time fluorescence quantitative PCR, and the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-c) and high-density lipoprotein cholesterol (HDL-c) in serum were measured at the first and last examination. The results show that, after the drug treatment, compared with the model group, each drug group showed a lipid-lowering effect. Especially, coptisine, palmatine, jatrorrhinze were significantly reduced TC, TG, LDL-c (P < 0.05, P < 0.01), and increased HDL-c (P < 0.01). In addition, they also increased mRNA expression of the LDLR in liver and HepG2 cells. The results showed that alkaloids from Coptidis Rhizoma can regulate lipid metabolism disorder, and coptisine have the best lipid-lowering effect.

Objective To discuss the operative methods and cnrative effect of calcaneal tuberosity fracture.Methods The data of 15 patients with calcaneal tuberosity fracture was retrospectively analyzed who received treatment between January 2008 and June 2011.There were 9 males and 6 female,with the age ranging from 31 to 68 years (average,51.4 years).All the patients had unilateral acute injury,with the left foot in 7 cases and the right foot in 8 cases.According to the Beavis classification,there were 3 cases in type Ⅰ and 12 cases in type Ⅱ.All the cases in type Ⅰ and 10 cases in type Ⅱ were treated with open reduction and screw fixation.The other 2 cases in type Ⅱ with larger fragment involving a portion of the subtalar joint were treated with plate and screw fixation.The effect of the treatment was assessed according to the ankle and hindfoot score system of American Orthopaedic Foot and Ankle Society (AOFAS) after the operation.Results Ten patients were followed up for 12 to 36 months (average,20 months).The healing time in these patients ranged from 8 to 25 weeks (average,12 weeks).The postoperative score ranged from 47 to 100 points (average,91.1 points).There were 7 cases which received excellent effect,2 cases,good,and 1 case,poor.The rate of excellent and good was 90％.Necrosis of skin and soft tissue and exposure of the plate happened to one patient,who eventually healed after 3 weeks by debridement with plate preserved and peroneal artery perforator flap transplantation.Loss of reduction happened to another patient,who was treated with the revision surgery by open reduction and screw fixation again.Conclusion To patients with obvious Fracture displacement whose soft tissues are irritated severely.Emergency open reduction and internal fixation operation should be offered to prevent the necrosis of the flaps as far as possible.To patients with small fractures,it is advisable to choose open reduction and large diameter screw fixation,while plate and screw fixation may be better for patients with larger tuberosity fragment,especially when the fracture line extends to the facet of the subtalar joint.

Objective　To investigate the feasibility of applying transvescal approach laparoendoscopic single-site radical prostatectomy (TVSSLRP) and assess the oncological and functional outcomes.Methods　Eight patients with clinically localized prostate cancer (PCa) of low risk underwent TVSSLRP.Demographic data were accrued including patient age,body mass index (BMI),preoperative PSA level,the International Index of Erectile Function 5,biopsy Gleason score,clinical TNM stage and D'Amico risk classification.One surgeon performed all TVSSLRP procedures.A homemade triple-port was introduced percutaneouly into the bladder to establish pneumovesicum through a 4 cm incision.The major steps of the surgery were described as follows:initial incision was made along posterior margin of the bladder neck to expose bilateral vas deference and spermatic vesicle.After opening Denonvilliers' fascia and extending the space to lateral prostatic pedicles,an intra-fascial nerve sparing procedure was performed.The puboprastatic ligaments were then separated close to the prostate surface and the dorsal vein complex was cautiously swept off.Subsequently,careful apical dissection and urethral transection was sequentially conducted. To reduce the tension of vesico-urethral anastomosis,3 additional incisions parallel to vesio-urethral margin were created and a novel tension - reduced V-LocTM barbed polydioxanone sutures was used.　Results　All the operations were successfully performed and there was no conversion to standard laparoscopic approach or open surgery.The total operative time range was 75 - 180 min with mean time of 125 min.The blood loss was 85 -450 ml with mean 140 ml and no blood transfusion was required.The catheter was removed after a mean (range) of 14 (9 -16) days.No intra-operative complications occurred. No patient had positive surgical margins.The mean (range) hospital stay was 17 (13 -25) days after surgery. All the cases were continent after removal of the catheter.No cases demonstrated vesico-urethral stricture and biochemical recurrence on 12 - 18 months follow up postoperatively.　Conclusions　TVSSLRP is technically feasible for cases with organ-confined prostate cancer with good oncological and functional results.

Objective To investigate the therapeutic effects, safety of ureteral calculus accom panied with granulation treated with pneumatic lithotripsy and two-macron laser via transurethral uret eroscopic. Methods From June 2007 to March 2010, 38 cases of ureteral calculus accompanied with granulation were treated with 2 μm laser and pneumatic lithotripsy via ureteroscope. All the patients had middle to severe hydronephrosis. The granulation under the calculus was vaporized with the 2 μm laser, and then the ureteral stone was fragmented with pneumatic lithotripsy. The clinical datum,stone disintegration rate, lithagogue rate and complication were retrospectively analyzed. Results Among 38 cases of ureteral stones, rate of successful fragmentation in a single procedure was 92%(35/38). The operation time ranged from 15 to 45 min, mean (23.0±6.5)min. Estimated the intraoperative blood loss was (7.0±4.5)ml. The postoperative hospitalization time was (5.2±0.6)d. Two upper ureteral stones were pushed back to the renal pelvis and a conversion to extracorporeal shock wave lithotripsy (ESWL) was needed. The insertion of the ureteroscope was failed in 1 case who was accepted open operation finally. Among the 37 cases treated via ureteroscopy, stone clearance rate was about 86% after operation 1 month. Follow-up examinations for 3-15 months (mean 8 months)showed no ureteral stenosis or urinary infection. Conclusion 2 μm laser and pneumatic lithotripsyvia ureteroscope could be a highly effective and safe therapy for treatment of ureteral stone with granulation.
