Objective To observe the therapeutic effect of the integration of Longji-Huoluo pill and mild manipulations Tuina therapy for the teenagers with lumbar intervertebral disc protrusion. Methods Eligible teenager patients with lumber intervertebral disc protrusion were randomly classified into two groups according to the single blind method and the treating sequence, 69 patients in the treatment group and 58 patients in the control group. The Longji-Huoluo pill and mild Tuina manipulations were adopted on the basis of the convertional treatment in the treatment group. While ibuprofen sustained release capsules and mecobalamin were given to the control group beside the convertional treatment. Both groups were treated for 4 weeks. The CT examinations were applied before and after the treatments to observe the absorption of the prolapsed lumber intervertebral disc. The Visual Analogue Scale (VAS) was used to test the pain degree and to estimate the clinical effect. Results The VAS scores in the treatment group (4.03 ± 1.67 vs. 5.41 ± 1.55, t=10.121) and the control group (3.61 ± 1.34 vs. 5.96 ± 1.71, t=11.086) after treatment were significantly lower than those before treatment (P<0.05). The sagittal diameters of the prominence in the treatment group (2.12 ± 1.89 mm vs. 4.62 ± 0.34 mm, t=2.281) after treatmentwas significantly lower than that before treatment (P<0.05). The total effective rate of the treatment group was 87.0%(60/69), and the control group was 72.4%(42/58). Statistical significance was detected on the difference of the two groups (U=1.913, P=0.043). Conclusions The integration of manipulations can effectively relieve the pain and can return the prominent disc. The therapeutic effect is considered equivalent to western medicine.

Objective To compare the curative effects of extraperitoneal laparoscopic hernia repair and tradi-tional hernia repair in the treatment of inguinal hernia.Methods The clinical data of 200 inguinal hernia patients in our hospital from October 2013 to Novermber 2015 were retrospectively analyzed.They were divided into traditional hernia repair group (100 cases)and laparoscopic hernia repair group (100 cases)according to different surgical treatment.The operation time,bed activity time and hospital stay of the two groups were detected.The uroschesis, hydrocele,incidence of postoperative pain and recurrence rate of the two groups were detected.Results The opera-tion time between the two groups had no significant difference(t =1.74,P >0.05).The bed activity time[(2.6 ± 1.6)h]and hospital stay[(5.7 ±2.1 )d]of the laparoscopic hernia repair group were better than the traditional hernia repair group[(9.1 ±3.3)h,(7.4 ±2.3)d,t =17.72,5.46,all P <0.05].The uroschesis 3.0%,hydrocele 0,incidence of postoperative pain 10.0% and recurrence rate 0 of the laparoscopic hernia repair group were lower than the traditional hernia repair group(21.0%,15.0%,50.0%,12.0%,χ2 =15.17,15.34,39.11,11.69,all P <0.05).Conclusion The recovery is fast in inguinal hernia patients treatment by extraperitoneal laparoscopic hernia repair,complication is little,which is worthy of application.

Objective To study the changes of lipid levels and body weight during the treatment of bipolar disorder by lithium carbonate combined with olanzapine or lithium. Methods Lipid and body weight was measured in forty-six patients with bipolar disorder in the first six months (treated by lithium carbonate combined with olanzapine) and in the second six months (treated by lithium only). Then the results were compared with the data before the treatment. Results When the first six months was over,the levels of the total cholesterol, triglyceride and apolipoprotein B increased(P＜ 0.05 ) ,and when the second six months was over,the levels of the total cholesterol,triglyceride,low density lipoprotein cholesterol (LDL-C),and apolipoprotein B increased Significantly (P ＜ 0.05 ). The levels of the total cholesterol, triglyceride, LDL-C were more than the normal level,but apolipoprotein B didn't exceed the normal level. When the first six months was over, the body weight was higher than that before treatment [ (68.70 ± 8.35 ) kg vs. (64.85 ±7.52 ) kg, P ＜ 0.05 ]. When the second six months was over, the body weight [ (71.72 ± 7.96 ) kg ] was higher than that at the end of the first six months (P ＜ 0.05 ). Gender difference showed non-statistical significance.Conclusions The lipid levels and body weight will both increase whether treated with lithium carbonate combined with olanzapine or with lithium only. The lipid level changes apparently in treatment with lithium separately, and the risk of coronary heart disease will increase.

Objective To observe the influence of calcitriol combined with prolonged hemodialysis on parathyroid hormone (PTH),phosphorus and calcium in maintenance hemodialysis patients with refractory secondary hyperparathyroidism.Methods Twenty-two maintenance hemodialysis patients received prolonged hemodialysis (3 times per week and 6 hours each session) and therapy with calcitriol (3 times per week and 1 μ g each time) for 3 months.The levels of serum PTH,calcium and phosphorus of these patients were recorded before and after treatment.Results Compared with that before treatment,the level of serum PTH and phosphorus was decreased significantly[(484.21 ± 230.18) nmol/L vs.(750.53 ± 327.41) nmol/L,(1.49 ±0.27) mmol/L vs.(2.37 ±0.76) mmol/L],but calcium was increased after treatment [(2.35 ±0.32) mmol/L vs.(1.81 ±0.53) mmol/L],and there was significant difference (P ＜0.05).Conclusions The treatment of calcitriol combined with prolonged hemodialysis not only effectively clear phosphorus and PTH but also increase calcium in maintenance hemodialysis patients.The therapeutic schedule is good to maintenance hemodialysis patients with refractory secondary hyperparathyroidism.

Objective To explore the clinical effects of pedicled omentum in preventing anastomotic leakage after resection of colorcctal cancer complicated with intestinal obstruction.Methods The clinicopathologic data and anastomotic leakage rate of 102 patients with colorectal cancer undergoing resection from Dec.2012 to Dec.2015 were analyzed.Results Seven patients in the control group developed anastomotic leakage.Only 1 patient in the experimental group developed anastomotic leakage.The incidence of anastomotic leakage in the control group was 12％,while that in the experimental group was 2％ (x2 =4.250,P =0.039).Of the 7 patients complicating anastomotic leakage in control group,1 died of multiple organ failure,1 was cured with conservative treatment,and 5 were done with diverting stoma.The one leakage in experimental group was cured by conservative treatment.Conclusion Pedicled omentum is useful in the prevention of anastomotic leakage after resection of colorectal cancer in settings of intestinal obstruction.

Objective To discuss the value of leukocyte-targeted myocardial contrast echocardiography (MCE) as a tool in observing the degree of acute rejection after heart transplantation. Methods Abdominal heterotopic cardiac transplantation was performed on 32 rats successfully, among which 8 isografts served as group A, and groups B, C and D involved 8 allografts respectively. The rats in groups B and C were treated with cyclosporine A (CsA) at a high dose (10mg· kg-1 · day-1 ), a low dose (3 mg · kg-1 · day-1 ) from 3rd day before transplantation respectively.The rats in groups A and D were untreated with CsA. MCE was performed during continuous intravenous SonoVue injection postoperatively on the third day after operation. We performed 2 types of MCE: perfusion imaging and leukocyte-targeted imaging. The images were obtained at 20 s and 5 min after injection of contrast agent. The value of the contrast image grayscale (GS) was measured by image analyzer (GS20s, GS5 min). GStarget was calculated as the GS5min minus the GS20s in the same rat.Postmortem histology was performed after observation. The degree of myocardial rejection was determined by HE-stained graft myocardium. Immunohistochemistry was performed to quantify the CD3-positive cells, and correlation analysis was performed between CD3-positive cell count and GS20s,GS5min, GStarget. Results Perfusion imaging showed no significant difference in myocardial GS20s of each group. Leukocyte-Targeted imaging exhibited a clear gradient in these groups (P＜0. 05). There was significant difference in GStarget of each group (P＜0. 001). Postmortem histology showed 0- Ⅰ grade rejection in group A, Ⅰ -Ⅱ grade rejection in group B, Ⅱ-Ⅲ grade rejection in group C, Ⅲ-Ⅳ grade rejection in group D. Immunohistochemistry revealed the CD3-positive cell infiltration was increased in turn from the group A to the group D. There was a significantly positive correlation between the CD3-positive cell count and GStarget ( r = 0. 86, P ＜ 0. 001 ). Conclusion Leukocyte-targeted contrast echocardiography may thus offer a noninvasive and effective ultrasound imaging technique for detecting the degree of acute cardiac transplant rejection.

Objective To construct and identify an eukaryotic expression plasmid containing rat hepatocyte growth factor(rHGF)gene and rat augmenter of liver regeneration(rALR)gene,so that to provide experimental basis for developing new treatments of hepatic fibrosis.Methods The gene fragments of rHGF and rALR were amplified from recombinant prokaryotic plasmid pUC18-rHGF and pUC18-rALR by polymerase chain reaction(PCR),respectively,then were spliced by overlap extension PCR with a linker,and the fusion gene rHGF-linker-rALR was constructed.The fusion gene was directionally inserted into the eukaryotic expression plasmid pcDNA3.1 between restriction sites of Kpn Ⅰ and Xba Ⅰ to construct the recombinant eukaryotic expression plasmid pcDNA3.1-rHGF-linker-rALR,and the new constructed recombinant plasmid was identified by double restriction digestion and DNA sequencing.Results DNA fragments of 2200 bp and 400 bp were observed after the electrophoresis of products amplified from recombinant prokaryotic plasmid pUC18-rHGF and pUC18-rALR,respectively,which was consistent with the theoretical value.The electrophoresis of fusion gene rHGF-linker-rALR obtained by overlap extension PCR technique showed only a 2 600 bp DNA fragment,which was in accordance with the expected value.Electrophoresis of products of pcDNA3.1-rHGF-linker-rALR digested with Kpn Ⅰ and Xba Ⅰ showed two DNA fragments with 2600 bp and 5400 bp,which were both consistent with the expected value.The sequences were confirmed correctly by DNA sequencing.Conclusion The recombinant eukaryotic expression plasmid pcDNA3.1-rHGF-linker-rALR is successfully constructed,which provides experimental basis for developing gene therapy of hepatic fibrosis.

Purpose To study the expression of HPV L1 protein and p16 in various cervical lesions and to explore the value of HPV L1 protein and p16 immunostaining in predicting the progression from CIN1 to CIN3 and squamous cell carcinoma (SCC).Methods Expression of HPV L1 protein and p16 in 18 cases of CIN1, 9 cases of CIN2, 8 cases of CIN3 and 6 cases of SCC was detected by immunohistochemistry.Results The average positive rates of HPV L1 protein in cervical lesions were 26.8%, and HPV L1 protein was positive in 38.9% of CIN1 and 44.4% of CIN2, but in 0 of CIN3 and SCC. In contrast, the average positive rate of p16 protein in cervical lesions was 68.3%, p16 protein was positive in 38.9% of CIN1and 77.8% of CIN2, but in 100% of CIN3 and SCC. p16-/HPV L1+ and p16-/HPV L1- cases represented 61.1% of CIN1, but 0 of CIN3 and SCCs, whereas p16+/HPV L1- cases represented 100% of CIN3 and SCC.Conclusions Expression of HPV L1 protein decreases whereas p16 protein increases with lesion progression. p16+/HPV L1- cases have the potential for progression, whereas p16-/HPV L1+ and p16-/HPV L1- cases may not be progressive lesions or potentially in remission.

Objective To evaluate the therapeutic effects of recombinant expression plasmid containing hepatocyte growth factor (HGF) and augmenter of liver regeneration (ALR) on rats with hepatic fibrosis. Methods Ninety Sprague-Dawley rats, which had been established into hepatic fibrosis models, were equally divided into 6 groups: blank group, pcDNA3.1 therapy group,pcDNA3.1-HGF therapy group, pcDNA3. 1-ALR therapy group, pcDNA3.1-HGF and pcDNA3. 1-ALR combined therapy group, and pcDNA3. 1-HGF-ALR therapy group. Zero point one μmol of blank or plasmid was injected into model rats in each group by tail vein once a day for 3 days. Model rats in blank group didn't receive any treatment. Additional 10 rats were chosen as control group, which were not given any interference during the experiment. All rats were sacrificed 4 days after end of treatment. Liver tissues were reserved for observing pathologic changes after HE staining and detecting proliferating cell nuclear antigen (PCNA) and c-jun by immunohistochemistry. Measurement data were compared by single-factor analysis of variance. Comparison between groups was done by SNK test. Enumeration data were analyzed by Fisher's exact test. Results In blank group and pcDNA3.1 therapy group, hyperplasia of fibrous connective tissue was very obvious, false lobules were formed. There was no significant difference between these two groups (x2 =0. 317,P= 1. 000).In the 4 remaining groups, hepatic fibrosis all achieved different degree of amelioration, and the therapeutic effect of pcDNA3.1-HGF-ALR was optimal. In control group, the expressions of PCNA and c-jun in liver tissues were low, with absorbance value of 8.6±1.9 and 3.2 ± 1.2, respectively. In blank group and pcDNA3. 1 therapy group, the expressions of PCNA and c-jun were obviously increased, with absorbance value of 24. 1±3.0, 24.5±4.3 and 23.8±3.1, 24.9±4.2, respectively,which were significant different from control group (all P＜0.01). In the 4 remaining groups, the expressions of PCNA were all obviously increased, and expressions of c-jun were all obviously decreased. The maximum change scope was observed in pcDNA3. 1-HGF-ALR therapy group.Conclusions The recombinant expression plasmid pcDNA3. 1-HGF-ALR can effectively ameliorate experimental hepatic fibrosis of rats. The anti-fibrosis effects are achieved probably by up-regulating PCNA expression and down-regulating c-jun expression.

BACKGROUND:More and more evidence suggests that macrophages and inflammation reactions are involved in the formation and development of nephrolithiasis. Previous studies have found that calculi crystals can stimulate macrophages to release high mobility group protein B1.
OBJECTIVE:To investigate the synergistic effect of high mobility group protein B1 in calcium phosphate induced release of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages.
METHODS:(1) The induced U937 cells were respectively stimulated with RPMI (blank), 100 mg/L calcium phosphate, 100μg/L high mobility group protein B1 and 100 mg/L calcium phosphate+100μg/L high mobility group protein B1 for 1, 2 and 4 hours to col ect cellsupernatant. (2) The induced U937 cells were respectively stimulated with 100 mg/L calcium phosphate, 100 mg/L calcium phosphate+10μg/L high mobility group protein B1, 100 mg/L calcium phosphate+50μg/L high mobility group protein B1, 100 mg/L calcium phosphate+100μg/L high mobility group protein B1 for 4 hours to col ect cellsupernatant. Levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 were determined by ELISA.
RESULTS AND CONCLUSION:The levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 in the cellculture supernatant of 100 mg/L calcium phosphate group and 100μg/L high mobility group protein B1 group were both higher than those in the blank group in a time-dependent manner (P<0.05). The levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 in the cellculture supernatant of different concentrations of high mobility group protein B1 groups were al higher than those in the 100 mg/L calcium phosphate group in a concentration-dependent manner (P<0.05). The results suggest that both calcium phosphate and high mobility group protein B1 can induce the release of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages and the high mobility group protein B1 has the synergistic effect with calcium phosphate to induce interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages.
