Objective To study the protective effect of propofol on lipopolysaccharide (LPS)-induced Ana-1 cell damage.Methods The LPS-induced inflammation damage of Ana-1 cells was es-tablished as a model.Ana-1 cells were divided into control group(group C),LPS group(group L), LPS+propofol 10μmol/L group(group LP1),LPS+propofol 20μmol/L group(group LP2),LPS+propofol 40 μmol/L group(group LP3),and LPS+propofol 80 μmol/L group(group LP4),respec-tively.Cell survival rate was assessed using MTT,interleukin 1βand 6,and tumor necrosis factors (TNF-α)were determined.Results Survival rate of Ana-1 cells in group L was lower than that in group C,while it was significantly improved in group LP1,LP2,LP3,LP4 in a dose-dependent man-ner (P <0.01);IL-1β,IL-6,TNF-αrelease was significantly higher in group L than in group C;IL-1β,IL-6,TNF-αrelease significantly reduced in group LP1,LP2,LP3,LP4 (P <0.01)in a dose-dependent manner (P <0.01).Within the selected dose range in this experiment,group LP4 had the best protection effect.Conclusion Propofol can reduce inflammation damage of Ana-1 cells caused by LPS.

Objective To evaluate therapeutic effect of transluminal angioplasty and stenting on arteriosclerosis related iliac arterial occlusive disease. Methods This retrospective study included a total of 61 cases (76 limbs) with iliac arterial atherosclerotic occlusive disease, grading as TASC A (n =29),B (n = 16), C (n = 11) and D (n = 5). Percutaneous interventional reconstruction and stent implantation were carried out in our hospital from December 2002 to December 2008. Results In 61 patients (76 lesions) 63 stents were implanted successfully with the success rate of 93% (71/76). The rate of clinical improvement was 100% among the patients who had primary technical success. The ankle-branchial index (ABI) improved from an average of 0. 33 ± 0. 17 before intervention to 0. 72 ± 0. 20 on the day following intervention (P < 0. 05). All cases were followed up between 6 month and 60 month. One year patency rate in all treated lesions was 90% (92% in the TASC A and B, 84% in the TASC C and D).Three year patency rate in all was 75% (80% in the TASC A and B, 63% in the TASC C and D). Five year patency rate was 72%. Conclusion There is a tendency towards utilizing transluminal angioplasty and stenting to treat iliac arterial occlusive disease as a therapy instead of traditional vascular surgery.

Objective To investigate the therapeutic effect of acupuncture for restoring consciousness and inducing resuscitation in promoting revival of coma for the patient of diffuse axonal injury(DAI). Methods 60 cases of DAI (GCS≤ 8) were randomly recurited into a control group and a treatment group. The control group was treated by routine treatment, while the treatment group was treated with acupuncture on the basis of routine treatment .The improving rate of consciousness at the two months of treatment was compared between the two group, and the prognosis was evaluated according to GOS scores. Results The revival rate in the treatment group was 86.7%, higher than that of 60.0% in the control group (P<0.05). The revival time in the treatment group was shorter than the control group (X2=5.45、 t= 8.051, P<0.05 ) .Conclusion The integrated therapy of acupuncture for restoring consciousness and inducing resuscitation and western medicine can promote the effect of coma revival and improve life condition for the patient of DAI.

Helicobacter pylori (H. pylori) is one of the most common pathogens in human and it is closely related to gastrointestinal diseases. It is essential for us to understand the transmission process of H. pylori to prevent its spreading. The oral cavity has been proposed as a reservoir for gastric H. pylori, which has been detected by culture and polymerase chain reaction (PCR) in both dental plaque and saliva. Some researchers have proposed H. pylori in oral cavity may play an important role in its transmission and reinfection. Oral-oral or fecal-oral transmission are thought to be the most possible transmit way. This review will discuss the evidence for the role of the oral cavity in the transmission of H. pylori, the difficulties encountered in addressing this topic and possible directions for future research. Oral H. pylori may also play a role in the diagnosis and prevention of deceases related to H. pylori such as gastritis, gastric ulcer and gastric carcinoma. The recent progresses in this area are also reviewed. Moreover, we also discussed the relationship between oral H. pylori and oral deceases like periodontal disease and oral ulcer.

Objective To investigate the feasibility of methotrexate incision and different methods of administration combined with hysteroscopic surgery for cesarean scarpregnancy (CSP).Methods Retrospective analysis of 106 patients with CSP in our hospital from January 2001 to December 2015 were.The patients were divided into two groups, group A of 66 cases: methotrexate ( MTX) incision and systemic administration combined with hysteroscopic surgery group B of 40 cases: methotrexate combined with hysteroscopy surgery.The operation time, intraoperative blood loss, preoperative hospital stay, the time of blood HCG decreased to normal, the total amount of MTX and the abnormal rate of liver function were compared between the two groups, and the factors affecting the prognosis of CSP were analyzed.Results The preoperative hospitalization time and abnormal liver function of the two groups were compared, the difference was statistically significant(P<0.05).A group of patients with success and failure, blood HCG before treatment, gestational sac and bladder wall thickness of the myometrium (MT), the difference was statistically significant (P<0.05).The median gestational sac diameter ( GS) of patients with successful treatment was 17.1 mm, and the median number of patients was 6.2 mm, and the difference was statistically significant between the two groups ( GS ) , the difference of GS between the two groups was statistically significant ( P<0.05 ) . Conclusion Methotrexate incision and systemic administration methods combined with hysteroscopy treatment compared with systemic administration combined with hysteroscopy is a safe and effective method and the hospitalization time is short, but the MT >3 mm, before treatment, blood HCG≤20000IU/L, GS≤40 mm CSP more secure.

Renal cell carcinoma is one of the most common urinary tract cancers, accounting for 90% of renal cancer cases, and the clear cell renal cell carcinoma is its most common subtype. Because of poor response to conventional anti-cancer treatment, metastasis may occur in the early stage of renal cell carcinoma. The high degree of metastasis of renal cell carcinoma determines the necessity and importance of early diagnosis. Although a lot of researches about renal cell carcinoma have been carried out, its underlying mechanisms still remain unclear. Recent studies have shown that spot-type POZ protein (SPOP) can perform biological functions in a cancer type-specific way. Based on the latest findings, this article reviewed the current research status and prospectives of SPOP in renal cancer cells.

Objective To evaluate recanalization for TASC-D type iliac artery lesions.Methods Between June 2006 and June 2010,26 patients with a total of 31 limbs of the TASC-D iliac artery lesions underwent endovascular procedure. Results Technical success rate was 90.3% (28/31).Clinical symptom improvement rate was 100%. Forty-four stents were placed in 28 limbs of the 24 patients.Eleven patients underwent an associated procedure; femoropopliteal endovascular procedures in 8 cases,femoro-popliteal bypass in 3 cases. Eight patients underwent an intravascular ultrasound thrombolysis.Postoperative ankle-brachial index ( ABI) was increased by more than 0. 15 in all patients. Twenty-two patients(26 limbs) were followed-up for 3 -44 mos, the primary patency rate at 12 months was 90% ,and cumulative patency rate was 95%. At 36 months primary patency rate was 70% , and secondary patency rate was 80%. Conclusions Because the technical success rate is high, endovascular techeniques are the choice of therapy in high risk patients with TASC-D type iliac artery lesions.

BACKGROUND:The template method used in cementless total hip arthroplasty is influenced by many factors,so the accuracy is poor.Studies demonstrated that femoral isthmus plays an important role in total hip arthroplasty,which affect femoral prosthesis.OBJECTIVE:To discuss the effects of femoral isthmus on cementless total hip arthroplasty.METHODS:The images of 4 cadaver femoral isthmus were obtained by computer tomography.The relations between femoral component and cortical bone contact were observed on coronal slices by sawing manully.The longest and the smallest medullary canal dimensions and the cortical thickness of femoral isthmus were measured by CT films from 50 patients (55 hips) prepared forprimary total hip arthroplasty.The size of prosthesis was predicted based on the smallest medullary canal dimension of isthmus.And the conventional preoperative template was served as control.RESULTS AND CONCLUSION:There were a press fit and good contact between the femoral component and cortical bone of isthmus in 3 cadaver femoral bones.In 50 patients,the longest medullary canal dimensions of femoral isthmus were 8.2-22.4 mm(mean 14.2±3.1 ram).The smallest medullary canal dimensions of femoral isthmus were 6.1-17.9 mm[mean (10.2±2.9) mm],and the cortical thickness of femoral isthmus were 2.7-12.7 mm[mean (7.5±1.8) mm].The results of CT-isthmus measurement method predicted sizes were excellence in the 50.9% cases.There was statistically significant difference of predicted sizesbetween the excellence rate of CT-isthmus measurement method and the rate of control (P＜0.05).Particularly,the excellence rate of CT-isthmus measurement method was 63.9% in the group aged below or equal to 65 years.When the ratio of the longest medullary canal dimensions and the smallest medullary canal dimensions of femoral isthmus was large than or equal to 1.4,the excellence rate of CT-isthmus measurement method was 70%.The press fit and good contact between the femoral component and femoral isthmus plays a very important role in stabilizing of femoral prosthesis in total hip arthroplasty.The predicted sizes of femoral prosthesis depending on the medullary canal dimensions of femoral isthmus measured by CT film has better accuracy than the conventional preoperative template.

Objective To observe any rehabilitative effects of individualized exercise training in the treatment of rotator cuff injury in elite table tennis players.Methods Forty table tennis players from the Chinese National Team were studied.Twenty (the experimental group) had rotator cuff injuries and 20 without the injury formed the control group.An individualized rehabilitation treatment protocol was prepared for each of the players in the experimental group and implemented twice weekly for a total of 8 weeks.There was no intervention for the control group.Before and after the treatment,both groups were assessed using a questionnaire for disabilities of the arm,shoulder and hand (DASH),a motion assessment,and BIODEX isokinetic muscle testing.Results There were significant differences in average DASH scores between the two groups,with the experimental group scoring higher than the controls both before and after the treatment.Before the treatment,at angular velocities of 60°/s,180°/s and 300°/s the peak moments of the ER (external rotation,ER) and IR (internal rotation,IR) muscles and the ER/IR ratio were all lower in the experimental group than among the controls.However,after the treatment the performance of the experimental group had improved in all three tests.Conclusion The ER/IR ratio of the dominant shoulder of table tennis players with rotator cuff injury is lower than that of the players without the injury,but individualized rehabilitation treatment can effectively increase the ratio and help to improve their shoulder function.
