OBJECTIVE: To explore effect and significance of lateral closed high tibial osteotomy on recovery of activity of knee joint. METHODS: From February to December 2018, 78 patients with knee osteoarthritis who were treated by high tibial osteotomy for the first time were selected as the observation group, including 46 males and 32 females, aged from 55 to 73 years old with an average age of (61.78±6.39) years old, the course of disease ranged from 6 to 24 months with an average of (16.52±4.25) months;according to Kellgren-Lawrence (K-L) grading, 36 patients were gradeⅡand 42 patients were grade Ⅲ. Another 20 healthy people were selected as healthy group, including 13 males and 7 females, aged from 56 to 73 years old with an average of (60.89±7.12) years old. The expression of miR-146 in peripheral blood was compared between observation group and healthy group. At the same time, patients in observation group were followed up for 6 months. The patients whose knee joint function returned to normal or improved significantly during the follow-up period were admitted as the effective group, while the patients whose knee joint function did not improve significantly or tended to aggravate were admitted as the ineffective group. The clinical data and the relative expression of serum miR-146 between effective group and ineffective group were analyzed. RESULTS: The relative expression of serum miR-146 in observation group after operation was significantly higher than that in healthy group ( CONCLUSION The expression level of serum miR-146 showed upward trend, which could regulate the differentiation of chondrocyte. The monitoring of miR-146 after operation has reference value for predicting the recovery of bone and joint function after operation.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

Objective To explore the efficacy of Fushe Jiedu Decoction combined with red light on viper bites injury limb swelling and the effects on the inflammatory cytokines. Methods Totally 90 patients were divided into control group and experimental group by using random number table method, with 45 cases in each group. The wounds of the control group were sterilized and given anti-snake venom serum, antibiotics, and tetanus immunoglobulin and supplemented with energy to correct water and electrolyte disturbances. The experimental group was treated with Fushe Jiedu Decoction based on the treatment of control group,150 mL each time,orally,twice a day; Red light was applied at the site of the most obvious swelling of the injured limb, 20 minutes each time, twice a day. The treatment lasted for 6 d. The swelling of injured limbs, serum C-reactive protein (CRP), 5-hydroxytryptamine (5-HT), histamine, tumor necrosis factor-α (TNF-α), interleukin (IL)-6 levels before and after treatment in the two groups were observed. Results Compared with before treatment, the swelling of the limbs disappeared significantly in the experimental group at 3 d and 6 d and in the control group at 6 d, with statistical significance (P<0.01). Compared with the control group at the same time point, the swelling of the limbs in the treatment group was significantly better than that in the control group at 3 d and 6 d, with statistical significance (P<0.01). Compared with before treatment, the levels of CRP, 5-HT, TNF-α, and IL-6 were significantly lower in the two groups, with statistical significance (P<0.05). After treatment, CRP, 5-HT and histamine in the experimental group were significantly better than that in the control group(P<0.05).Conclusion Fushe Jiedu Decoction combined with red light has good efficacy for viper bites injury limb swelling, which can reduce inflammatory cytokines levels of patients.

OBJECTIVE: To explore the relationship between the expression of EIIIA+ fibronectin in incised wound of rat's skin and injury time. METHODS: The wounding model was established by cutting the dorsal skin of 48 adult SD rats. The rats were sacrificed at the pre-set injury time as immediately, 0.5 h, 1 h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin samples were taken at the margin of wound. The expression of the EIIIA? fibronectin was detected by immunohistochemistry and Western blotting and the relationship be- tween its expression and injury time was observed. Results The expression of EIIIA+ fibronectin was not observed immediately. The basal cell of skin began to show positive expression 0.5 h after injury. With the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the Western blotting analysis. CONCLUSION The expression of EIIIA+ fibronectin could be used for estimation of injury time in the early stage of skin injury.

OBJECTIVE: To examine the expression of MMP-3 and TIMP-1 in the synovial fluid in knee joints with osteoarthritis before and after being treated with hyaluronic acid(HA), glucosamine sulfate(GS) and arthroscopic de bridment(AD), and to explore the therapeutic mechanism. METHODS: Sixty patients (64 knees) with osteoarthritis(OA) were randomly divided into HA group AD group and GS+AD group. Some patients from the HA group and the GS+HA group were selected, and served as HA' group and GS+HA' group. The expression of MMP-3 and TIMP-1 in the synovial fluid was measured by enzyme-linked immunosorbent assay (ELISA) before and after 4 week and 6 month therapy. RESULTS: The level of MMP-3 and the ratio of MMP-3/TIMP-1 in the synovial fluid decreased after being treated for 4 weeks, and the effect on MMP-3 and MMP-3/TIMP-1 lasted for 6 months in the HA group and the GS+HA groups. The levels of TIMP-1 increased significantly after being treated for 4 weeks only in the GS+HA group. The level of MMP-3 and the ratio of MMP-3/TIMP-1 in the synovial fluid decreased, but the level of TIMP-1 increased after being treated for 4 weeks, and the effect on MMP-3 and MMP-3/TIMP-1 lasted for 6 months. The level of MMP-3 and the ratio of MMP-3/TIMP-1 in the synovial fluid increased after being treated for 6 months compared with those for 4 weeks. The level of TIMP-1 increased in the GS group more than that in the HA group after being treated for 4 weeks. The level of TIMP-1 increased in the AD group more than that in the HA' group and the GS+HA' group after being treated for 4 weeks. CONCLUSION (1) HA, GS and AD all can decrease the level of of MMP-3 and the ratio of MMP-3/TIMP-1 in the synovial fluid in knee joints with OA. (2) The level of TIMP-1 in the synovial fluid has no difference before and after being treated with HA. The AD group and GS group can increase the level of TIMP-1, which indicates that the AD group or GS group might produce better therapeutic effect. (3) The level of TIMP-1 increased in the AD group is more than that in the HA' group and the GS+HA' group after being treated for 4 weeks, which indicates that the AD group might get better therapeutic effect than the other 2 groups. (4) One of the most important mechanisms of HA, GS and AD in treating OA might be attributed to the expression of MMPs and TIMPs in knee joints with OA.

BACKGROUNDPodocyte has inflammatory role in the development of diabetic nephropathy (DN). Mycophenolate mofetil (MMF), an anti-inflammatory agent, can suppress macrophage infiltration and reduce renal injury in streptozotocin-induced diabetic rats. Angiotensin II receptor blocker (ARB), another renal protecting agent, can decrease podocyte loss in DN. In this study, we detected the expression levels of monocyte chemoattractant protein-1 (MCP-1) and nephrin to evaluate podocyte's role in inflammatory reaction in DN, observe and compare the effect of MMF alone and in combination with valsartan, on preventing podocyte loss in streptozotocin (STZ) induced diabetic rats.

METHODSDiabetic model was constructed in uninephrectomized male Wistar rats by single peritoneal injection of STZ (65 mg/kg). The successfully induced diabetic rats were randomly divided into four groups: diabetes without treatment group (DM), valsartan treated group (DMV), MMF treated group (DMM), and combined therapy group (DMVM). Normal rats of the same sibling were chosen as control (NC). At the end of the 8th week, serum biochemistry, 24-hour urinary protein (UP) and the ratio of kidney weight/body weight (RWK/B) were measured. The rats were sacrificed for the observation of renal histomorphology through light and electron microscope. Nephrin, desmin and MCP-1 levels were detected by semi-quantitative immunohistochemical assays. Real-time quantitative PCR was used to detect the mRNA levels of nephrin and MCP-1.

RESULTSCompared with group NC, serum glucose level, 24-hour UP and RWK/B in group DM were significantly higher (P < 0.01), and the nephrin mRNA level in DM group was significantly lower (P < 0.05). The nephrin mRNA expression levels in group DMV, DMM and DMVM were all higher than that of DM group (P < 0.05) and no significant differences were found among the three treatment groups (P > 0.05). Treatment with MMF, valsartan or their combination could significantly decrease the 24-hour UP and RWK/B, and suppress glomerulosclerosis and interstitial fibrotic lesions in diabetic rats. In diabetic rats, the high expressions of desmin and MCP-1 in kidney were suppressed by valsartan, MMF or their combination.

CONCLUSIONSPodocytes are involved in the inflammatory reaction of diabetic rats. MMF could suppress MCP-1 and desmin expression, enhance nephrin expression, and attenuate proteinuria in diabetic rats. The combined therapy of valsartan and MMF did not show any superiority over monotherapies on renal protection. MMF may have renoprotective effect in early stages of diabetic nephropathy through preventing podocytes loss and anti-inflammatory activity.

OBJECTIVEIn order to accumulate experiences for improving the efficiency in serological tests, the present study on mixed testing of serum samples was performed by taking the serological test of trichinellosis and toxoplasmosis as the examples, and had proved the effects on cost-effectiveness of seroepidemiological survey of parasitic disease with method of mixed-samples test.

METHODSAccording to the binomial distribution principle, to develop an approach to the feasibility of mixed testing of serum samples, and to work on a cost-effectiveness analysis of one-by-one testing and mixed testing using hygienic economic analysis method was performed. For serological test of trichinellosis and toxoplasmosis, 3 kinds of mixed testing methods, namely 3 serum sample mixture, 5 serum sample mixture and 10 serum sample mixture, were performed.

RESULTSThe results showed that all the 3 kinds of mixed tests of trichinellosis and toxoplasmosis showing positive result if only 1 weak positive serum sample were mixed with. When the serum samples being mixed were all negative ones, then among the 24 groups tested with each kind of negative serum sample mixture of trichinellosis (3 serum samples, 5 serum samples and 10 serum samples), they all showed negative. However, among the 12 groups tested with 2 kinds of negative serum mixture of toxoplasmosis (3 serum samples and 5 serum samples), all showed negative while among the 18 groups tested with the 10 serum sample mixture, 16 groups showed negative and 2 were positive. The mixed testing of trichinellosis and toxoplasmosis showed that the efficiency of mixed testing was related to the serological positive rate of the parasitic diseases to be examined. When serological positive rate was 10%, the efficiency of mixed testing was higher in 4 serum sample group. When serological positive rate was 1%, the efficiency of mixed testing was higher in 10 serum sample group and when serological positive rate was 0.1%, the in crease of the size of mixed serum samples could decrease the number of testing, but the prerequisite was that there must be one positive sample, so that the positivity for all the mixed tests could be detected. If mixed testing were performed on all negative samples, no positivity could be detected.

CONCLUSIONThe result of cost-effectiveness analysis demonstrated that for seroepidemiological survey of parasitic diseases, the cost for mixed testing was low, especially when the serological positive rate was expected low (< or = 1%, thus the mixed testing could save a large amount of the cost.

OBJECTIVETo study the application of extraoral distraction devices in correction of various maxillo-mandibular deformities.

METHODSFrom 1997, 11 cases with various maxillo-mandibular deformities were corrected by distraction devices of designed by myself. 7 cases of then were the patients with cleft palate who have severe secondary maxillary hypoplasia. 1 case with micrognathia, 1 case with partial mandibular mentum defect, 1 case with lateral deviation of micrognathia and 1 case with hemimandibular hypertrophy. The mandibles were elongated, from 12 mm to 20 mm, the maxillae were elongated from 7 mm to 22 mm, the vertical mandibular distraction was 15 mm.

RESULTSAll cases were corrected satisfactorily and haven't any complications. In 1 cases the 1 Kischners pin had been pull out by loosen during distration. 4 Kischners pin were curved during vertical mandibular distration. Another case the maxillary hypoplasia appeared edge-to-edge and mild open occlusion after 4 weeks fixation.

CONCLUSIONThe extraoral distration osteogenesis provides a new method with many advantages for those maxillo-mandibular deformities that are difficulty corrected by ordinary orthognathic surgery.

OBJECTIVETo evaluate the effects of Huafenqinutang combined with vardenafil for the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with erectile dysfunction.

METHODSOne hundred and thirty-eight cases diagnosed as CP/CPPS with erectile dysfunction were randomized into trial group (70 cases) and control group (68 cases) for treatment with Huafenqinutang for 8 weeks, and in the former group, vardenaffil was added since the fifth weeks. All the cases were evaluated according to NIH-CPSI and IIEF-5 scores at 4 weeks and 8 weeks, respectively.

RESULTSAt the end of the fourth weeks, NIH-CPSI score was 13.1-/+4.7 in the trial group and 13.3-/+4.5 in the control group, which were comparable between the two groups (P>0.05) but significantly decreased compared with the pre-treatment scores in both groups (P<0.01). IIEF-5 score was also similar between the two groups (14.1-/+3.3 vs 14.3-/+5.0, P>0.05) but significantly increased compared with the pre-treatment scores in both groups (P<0.01). At the end of the eighth week, NIH-CPSI score was 7.8-/+2.2 and IIEF-5 score 20.1-/+4.4 in the trial group, which were significantly different from those at the end of the fourth week (P<0.01). In the control group, NIH-CPSI score was 12.7-/+2.3 and IIEF-5 score 14.3-/+4.5 at the eighth week, similar to those at the end of the fourth week (P>0.05). There were significant differences in NIH-CPSI and IIEF-5 scores between the 2 groups (P<0.01), and the change of NIH-CPSI score was negatively correlated with IIEF-5 score in the trial group (r=-0.89, P<0.01).

CONCLUSIONFor patients with CP/CPPS with erectile dysfunction, Huafenqinutang treatment in combination with vardenafil can effectively improve the erectile functions and decrease the NIH-CPSI score to favor the recovery from CP/CPPS.

OBJECTIVETo investigate the chromosomal aberration in sporadic colorectal carcinoma and its association with clinicopathological features.

METHODSComparative genomic hybridization(CGH) was used to screen the changes in the number of DNA sequence copies in 40 sporadic colorectal cancer patients in order to identify regions that contain genes important for the development and progression of colorectal cancer.

RESULTSIn 40 sporadic colorectal cancer, frequent gain at 20 q, 12 q, 13 q, 7 p, 7 q and 16 q were found, while loss was also found at 18 q, 5 q, 4 q, 8 pand 17 p. The number of chromosomal aberration was closely associated with tumor stage(P<0.05). No significant association was found between the number of chromosomal aberration and tumor site, histopathologic type and histologic grade.

CONCLUSIONSChromosomal aberration exists generally in sporadic colorectal carcinoma. The number of chromosomal aberration and gain of 20q are closely associated with tumor stage.
