Objective To optimize and simplify the survey method of Oncomelania hupensis snail in marshland endemic re?gion of schistosomiasis and increase the precision,efficiency and economy of the snail survey. Methods A quadrate experimen?tal field was selected as the subject of 50 m×50 m size in Chayegang marshland near Henghu farm in the Poyang Lake region and a whole?covered method was adopted to survey the snails. The simple random sampling,systematic sampling and stratified ran?dom sampling methods were applied to calculate the minimum sample size,relative sampling error and absolute sampling error. Results The minimum sample sizes of the simple random sampling,systematic sampling and stratified random sampling meth?ods were 300,300 and 225,respectively. The relative sampling errors of three methods were all less than 15%. The absolute sampling errors were 0.221 7,0.302 4 and 0.047 8,respectively. Conclusion The spatial stratified sampling with altitude as the stratum variable is an efficient approach of lower cost and higher precision for the snail survey.

Objective To compare the safety , surgery effects , pain scores of the close-distance-two-port video-assisted lobectomy and systematic dissection of the mediastinal nodes , and single-port video-assisted thora-coscopic surgery (VATS). Methods Between October 2012 and January 2015 in Peking University First Hospi-tal and Beijing Hospital , 269 patients who were going to be performed lobectomy and systematic lymph node dissection, were gathered and 205 patients were included in this study finally. Of the total, 122 patients were performed close-distance-two-port VATS , and 83 patients underwent single-port VATS. The clinical data were gathered, and statistically analyzed. Result In both groups, no severe postoperative complications or death oc-curred. No significant differences existed between the two groups in terms of intraoperative blood loss , duration and volume of chest tube drainage , postoperative pain score , hospital stay after surgery and hospitalization ex-penses (P > 0.05) but the data about operating time, number of dissected lymph nodes, complications(subcuta-neous emphysema , air-leak from the port of drainage tube and poor wound healing ) were significantly different (P < 0.05). Conclusions Compared with the single-port VATS, the method of close-distance-two-port video-as-sistant lobectomy and systematic dissection of the mediastinal nodes is safe and practicable with definite thera-peutic effect, less operation difficulty and complications.

Objective To investigate the characteristics of traditional Chinese medical syndrome types of fulminant and epidemic dengue fever patients admitted in Guangzhou and Xishuang banna in the year of 2013,and to ex plore the differences of etiology and pathogenesis, illness, and treatment for the patients in the two regions. Methods We collected the clinical data of 78 cases receiving integrative Chinese and western medicine from 255 patients admitted in Guangzhou Municipal Eighth People’s Hospital, and the clinical data of 39 cases receiving integrative Chinese and western medicine from 120 patients admitted in the People’s Hospital of Xishuangbanna Dai Nationality Autonomous Prefecture in the year of 2013. The traditional Chinese medical syndrome types and the syndrome scores of the total of 117 cases were investigated. The method of phenology was used for the analysis of epidemic time and epidemic region of dengue fever, and the theory of defense-qi-nutrient-blood syndrome differentiation of seasonal febrile diseases was used for the analysis of etiology and pathogenesis of dengue fever. Results ( 1) Dengue fever was epidemic in the first ten days of July and in the middle ten days of November of the year 2013 in Guangzhou region, and was epidemic in the middle ten days of August and the first ten days of October in Xishuangbanna region. The epidemicity of dengue fever in Guangzhou covered the end of summer and the whole autumn, and then disappeared before the coming of winter. In Xishuangbanna , the epidemicity of dengue fever was obvious in autumn, and disappeared in late autumn. ( 2) In the two hospitals, dengue fever patients were dominated by the syndromes of excessive heat in both Qifen and Xuefen, blood stasis blended with toxicity, excessive heat in Qifen, and lingering pathogens in order. (3) Before treatment, the scores of fever were higher in patients of Xishuangbanna hospital than those in patients of Guangzhou Eighth People’s Hospital ( P<0.01) . After treatment for 3 days, fever scores were improved in both hospitals (P<0.05 or P<0.01), but the differences between the two hospitals were insignificant (P>0.05) . After treatment for 6 days, fever disappeared in patients of both hospitals. (4) Before treatment, the scores of syndromes were higher in patients of Xishuangbanna hospital than those in patients of Guangzhou Eighth People’s Hospital ( P<0.05) . After treatment for 3 days, syndorme scores were improved in both hospitals ( P<0.01) , but the syndrome scores were higher in Xishuangbanna hospital than those in patients of Guangzhou Eighth People’s Hospital. After treatment for 6 days, syndrome scores were much improved in patients of both hospitals compared with those after treatment for 3 days (P<0.01) . Conclusion In dengue fever patients admitted in Guangzhou and Xishuangbanna region, the syndrome of excessive heat in both Qifen and Xuefen is the leading type, and then comes blood stasis blended with toxicity. The illness state of patients in Guangzhou region is milder than that of the patients in Xishuangbanna region, the time for symptom relief is about one week, and similar therapeutic effect can be achieved in the two regions .

BACKGROUND: Calcium sulfate/poly amino acid compound materials carrying triple anti-tuberculosis drugs have been proved to have excellent slow release performance based on our preliminary studies on the physical and chemical properties and the release properties of the compound materials.OBJECTIVE: To observe the slow release performance of the calcium sulfate/poly(amino acid) compound material carrying triple anti-tuberculosis drugs in a rabbit model of spinal tuberculosis.METHODS: Twenty-four New Zealand white rabbits were used to make L4-5 spinal tuberculosis models and divided into two groups in a random way following removal of tuberculosis lesions. Calcium sulfate/poly amino acid compound material carrying isoniazide, rifampicin, pyrazinamide or calcium sulfate/poly(amino acid)compound material with no drugs was implanted into the defect in the experimental or control group,respectively. At 2, 4, 6 and 8 weeks after implantation, the concentrations of isoniazid, rifampicin and pyrazinamide in the defect region, including the bone tissue, adjacent psoas major and inferior vena cava,were measured.RESULTS AND CONCLUSION: In the experimental group, the isoniazid levels in the damaged bone tissue and psoas major were kept in minimum bactericidal concentration (MBC) at 8 weeks after implantation and in the minimum inhibitory concentration (MIC) at the end of 12 weeks after implantation, while its level in the vein was kept in MBC at 2 weeks and in MIC at 8 weeks. The rifampicin levels in the bone tissue and psoas major were kept in MBC at 4 weeks after implantation and in the MIC at 8 weeks after implantation, while its level in the vein was kept MIC at 4 weeks.The pyrazinamide levels in the damaged bone tissue and psoas major were kept in MBC at 8 weeks after implantation and in the MIC until 8 weeks after implantation, while its level in the vein was kept MIC at 8 weeks. In the control group,there were no levels of isoniazid, rifampicin and pyrazinamide in the damaged bone tissue, adjacent psoas major and inferior vena cava in comparison with the baseline. These results show that isoniazid, rifampicin and pyrazinamide in the defect region can achieve sustained slow release in the rabbit model of spinal tuberculosis after implantation of the calcium sulfate/poly(amino acid) compound material carrying triple anti-tuberculosis drugs. In addition, the local drug concentration and duration in the defect region are better than those in the blood.

Objective To investigate the expression and relationship of TIP30(HIV-1 Tat interactive protein 2), vascular endothelial growth factor (VEGF) and MVD (detected by CD34) in the angiogenesis of human brain astrocytomas. Methods Expression of TIP30, VEGF and CD34 in 19 cases of normal brain tissue and 71 cases of astrocytoma were immunohistochemically examined with Elivision plus two-step method. Results The positive expression of TIP30 could be seen in cytoplasm of neuroglial cells and neurons of 19 normal brain tissues. The positive expression rate of TIP30 in 71 cases of astrocytoma was 33.80 % (24/ 71). The positive expression rate of TIP30 in astrocytoma of different grades was 52 % for grade Ⅱ, 34.78 % for grade Ⅲ and 13.04 % for grade Ⅳ. The positive expression rate of TIP30 in high grade (Ⅲ+Ⅳ) of astrocytoma was found significantly lower than that in low grade(Ⅱ) (χ2=5.71, P <0.05); The expression of VEGF and MVD detected by CD34 in astrocytomas were higher than that in normal brain tissue and increased as the tumor grade increased; In astrocytoma, the negtive correlation was found between the expression of TIP30 and VEGF (r=-0.428, P<0.05); no correlation was found between TIP30 and MVD(r=-0.065, P 0.05); the positive correlation was found between VEGF and MVD(r=0.684, P<0.01). Conclusion The positive expression rate of TIP30 in normal brain tissue is significantly higher than that in astrocytoma. The positive expression rate of TIP30 significantly decreases as the pathological grade of the astrocytoma increases; The expression of TIP30 and VEGF is negatively correlated in astrocytoma.

Objective To investigate the feasibility of Antituberculotic?loaded bone cement (ATLBC) prepared by mix?ing the anti?TB drugs Rifampicin (RFP), Isoniazid (INH), Pyrazinamid (PZA), Moxifloxacin (MFX) with Palacos R PMMA bone cement in Total Joint Arthroplasty treatment for Joint Tuberculosis. Methods Forty grams of Palacos R bone cement powder without antibiotics was mixed with 1 or 2 grams of RFP, INH, PZA and MFX respectively. According to ISO 5833:2002 stan?dard, 8 groups of ATLBC standard test specimen were prepared as experiment group and Palacos R PMMA bone cement with?out antibiotics was prepared as control group. Physical properties (such as the average dough time, curing time, maximum tem?perature), mechanical strength (such as the compressive strength, the bending resistance strength, the modulus of elasticity) and the concentrations of eluant drug in different time points of ATLBC were detected. Results In RFP (1 g), RFP (2 g), INH (1 g) and INH (2 g) group, the average dough time and curing time were longer than those in control group, which exceeded the standard scope of ISO, while the average maximum temperature was significantly lower than that in control group. The INH ( 1 g) group and INH (2 g) group hardened after mixing for 14 days. The RFP (1 g) group and RFP (2 g) group hardened after mixing for 30 days. Twenty minutes after mixing and hardening, the compressive strength, bending resistance strength and modulus of elastic?ity were significantly lower than the specified values of ISO standard. The physical properties and mechanical strength in PZA ( 1 g) group, PZA (2 g) group, MFX (1 g) group, MFX (2 g) group and control group were in accordance with the specified values of ISO standard, and they hardened after 20 minutes. In RFP (1 g) group, RFP (2 g) group, INH (1 g) group, INH (2 g) group, PZA (1 g) group, PZA (2 g) group, MFX (1 g) group and MFX (2 g) group, the concentration of eluant could maintain for 3 days, 7 days, 90 days, 90 days, 45 days, 60 days, 60 days and 60 days respectively. Conclusion RFP and INH mixing with Palacos R PMMA bone cement can hinder the aggregation of bone cement so they are unsuitable for preparing ATLBC. PZA and MFX mixing with Palacos R PMMA bone cement do not affect the physical properties of bone cement, with excellent mechanical strength and elu?tion properties. Because the minimal inhibitory concentration of PZA is higher and its antimicrobial activity maintains shorter time, while MFX maintains longer time in antimicrobial activity, it's more suitable for the preparation of ATLBC.

UNLABELLEDOBJECTIVE To investigate an operative method of combined resection of preseptal fat: and partial retro-orbicularis oculus fat (ROOF) for correction of upper eyelid heaviness, and evaluate the efficacy and safety of the method.

METHODSPreseptal fat lies widely under the orbicularis oculi in the upper eyelid, and retro-orbicularis oculus fat (ROOF) lies in the lateral supraorbital area. Combined resection of preseptal fat and partial ROOF was performed in patients selected by examination. The efficacy and safety were evaluated by follow-up study.

RESULTSFrom May 2011 to July 2013, 38 selected patients received the treatment with 3 months to 28 months follow up. The heaviness of upper eyelid improved in all cases. One patient developed postoperative hematoma, and another patient had a transient numbness over the lateral upper brow region. 37 patients were satisfied with the result.

CONCLUSIONSCombined resection of preseptal fat and partial ROOF was effective in reducing the heaviness of upper eyelid, without major complications. The operative method should be an important adjunct for selected patients undergoing blepharoplasty.
