Objective In order to investigate and evaluate the heating-ventilating-air conditioning (HVAC) systems in the public areas and therefore provide the support for the hygiene management. Methods According to Hygiene Criterion of HVAC System, 10 HVAC systems in 10 star grade hotels in Nanchang were selected and PM10 and the total count of aerobic bacterial in the air condition systems, the collected dust weight and the total count of aerobic bacterial in the dust in the inner surface of ventilation vessels, the legionella bacteria in cooling tower water were determined. Results The HVAC systems in the 10 hotels, 90.1% for the PM10 and 73.3% for the total count of aerobic bacterial in the air condition systems, 8.9% for the collected dust weight and 86.7% for the total count of aerobic bacterial in the dust in the inner surface of ventilation vessels were over the standard limits, the legionella bacteria were detected in two of the investigated HVAC systems cooling tower water. Conclusion The hygienic problems are existed in the ventilated systems in the air conditioners in the pubic places.The health supervision and monitoring must go on enhancing.

Objective To establish the method for quality standard of Fangzhi Biyan Tablet. Methods Radix Angelicae Dahuricae, Radix Paeoniae Alba, Radix Saposhnikiviae and Radix Glycyrrhizae in the tablet were identified by TLC. The content of Imperatorin in this medicine was determined by HPLC. The Agilent Eclipse XDB-C18 (4.6 mm?250 mm, 5 ?m) was used, mobile phase was methanol-0.1%phosphoric acid solution (65∶35), flow rate was 1.0 mL/min, detection wavelength was 248 nm. Results The TLC spots developed were fairly and simply identical. HPLC was accurate and reproducible. Imperatorin show a good liner relationship at range of 0.076～0.684 ?g, the recovery was 98.63% (RSD=1.52%). Conclusion These methods can be used to control the quality of Fangzhi Biyan Tablet effectively.

Objective To investigate the feasibility and clinical effect of hip joint arthrodesis with the application of Kirschner wire and reconstruction plate in the treatment of advanced tuberculosis in total hip joint.Methods A total of 30 patients with advanced tuberculosis of the hip in our hospital from March 2014 to April 2016 were divided as Kirschner wire group and reconstruction plate according to different surgical methods,with 15 cases in each group.The operation time,bleeding volume during operation (intraoperative and postoperative),fusion time,postoperative complications of two groups were observed and compared.Results Patients of two groups reached bony fusion.Compared with reconstruction plate group,Kirschner wire group had less blood loss,shorter operative time,longer fusion time,the differences were statistically significant (P ＜ 0.05).Conclusion Both Kirschner wire fixation and reconstruction plate arthrodesis are effective for patients with advanced tuberculosis of total hip joint,but the clinical efficacy of Kirschner wire fixation in hip arthrodesis was significantly better than the reconstruction plate.

ObjectiveTo investigate serum lipopolysaccharide (LPS) level in people with different glucose tolerances and to explore the relationship between LPS and insulin resistance/β-cell secretory function.Methods Sixty-seven subjects were recruited,including 23 with newly diagnosed type 2 diabetes ( T2DM),21 impaired glucose tolerance ( IGT),and 23 normal glucose tolerance (NGT).Serum LPS was assayed by limulus amebocyte lysate test ;expression of LPS toll-like receptor 4 (TLR4) on surface of plasma monocytes was measured by flow cytometric assays,and the changes of LPS levels by 0.5 hours and 2 hours after a high-fat diet were detected.Insulin resistance was evaluated by homeostasis model assessment for insulin resistance (HOMA-IR); β-cell secretory function was evaluated by homeostasis model assessment for β3 cell function ( HOMA-β )/HOMA-IR,increment in insulin in the first 30 minutes/increment in glucose in the first 30 minutes ( AIns30/ΔG30)/HOMA-IR,AUCIns120min/HOMA-IR.Results2 h LPS levels after a high-fat diet were significantly higher than fasting LPS levels [ NGT:0.96(0.33,0.99)vs 0.62 (0.22,0.64),IGT:1.08(0.53,1.22)vs 0.71 (0.39,0.82),T2DM:1.23 (0.62,1.43)vs 0.86( 0.45,0.94 ),EU/ml,all P＜0.01 ].Fasting,0.5 h,and 2 h LPS levels and fasting TLR4 levels of T2 DM group and IGT group were respectively higher than those of NGT group [ fasting LPS:0.86( 0.45,0.94 ),0.71 ( 0.39,0.82 ) vs 0.62(0.22,0.64),EU/ml;0.5 h LPS:1.10(0.55,1.18),0.84(0.50,1.07) vs 0.73(0.31,0.76),EU/ml;2 h LPS:1.23(0.62,1.43),1.08(0.53,1.22)vs 0.96(0.33,0.99),EU/ml; fasting TLR4:36.96( 17.22,55.19),30.34 ( 15.00,45.18 )vs 15.66 (6.09,9.76),MIF/105 cells,all P＜0.01 ].Fasting LPS,AUCLPS 120 min,and fasting TLR4 were positively correlated with insulin resistance index and negatively correlated with β-cell secretory function index ( P＜0.05 ).Multiple linear regression analysis showed that fasting LPS was an independent correlative factor of HOMA-IR and 0.5 h LPS was an independent correlative factor of (AIns30/AG30)/HOMA-IR and AUCIns Ins120min/HOMA-IR.ConclusionPeople with different glucose tolerances show differed LPS levels and its receptor TLR4 levcls,both of which are correlated with insulin resistance and β-cell secretory function,suggesting that LPS is associated with the pathogenesis of abnormal glucose regulation.

Objective To evaluate the therapeutic effects,acute and late side-effects of cisplatin plus 5-fluorouracil (PF) schemed chronomodulated chemotherapy combined with concurrent intensitymodulated radiotherapy(IMRT) for nasopharyngeal carcinoma.Methods A total of 48 nasopharyngeal carcinoma patients treated with chronomodulated chemotherapy plus concurrent IMRT were retrospectively studied.The radiation doses prescribed to the gross target volume GTVnx of nasopharyngeal,to the positive neck lymphnodes GTVnd,to the clinical target volume CTV1,and to CTV2 were 73.92-77.88,69.96,60.06-66.00 and 50.96-56.00 Gy respectively.The Kaplan-Meier survival analysis was used to calculate the local-regional progression-free rate.The acute and late side-effects were graded according to RTOG radiation morbidity scoring criteria.Results The complete remission (CR) rate was 41.6％(20/48) ; the partial remission (PR) rate was 47.9％ (23/48) ; the stable disease (SD) rate was 4.2％(2/48) ; and the local tumor control rate was 89.6％.Most of the patients had grade 1 to 2 acute side effects and grade 0 to 1 late side-effects.No grade 4 acute and late toxicity was observed.1,2,4-year survival rates were 93.8％,79.2％ and 64.5％,respectively.The DVH analysis showed that IMRT improved the total dose and dose per-fraction to the target volume with considerable dose reduction of the normal structures at the same time.Conclusions PF chronomodulated chemotherapy plus concurrent intensity-modulated radiotherapy for NPC could improve therapeutic effects with satisfactory tolerance of the side effects.

Granular cell tumor of the breast (GCTB) is a rare tumor which stems from Schwann cells.It is a largely benign tumor,but in the literature extremely infrequent cases can exhibit malignant characteristics.It tends to a particular problem as its characteristics are similar with breast carcinoma macroscopically,clinically,and radiologically.Typically,GCTB is benign and solitary lesion,yet including atypical GCTB and malignant GCTB,they can co-localize with breast malignancies multicentricity.The histopathological and immunohistochemical detection is the gold standard for diagnosis of GCTB up to now.And local expanded resection is the main treatment method at present.

Based on the needs of healthcare system reform, Australia has implemented activity based funding(ABF) payment mode nationwide, and established the Independent Hospital Pricing Authority as the specific implementation agency in 2011. The main responsibilities and functions of the ABF payment mode covers pricing of medical services, classification of healthcare services, collection of clinical data and cost accounting of healthcare services. ABF payment mode presents outstanding advantages in promoting the capacity of healthcare service, maintaining fairness of healthcare service supplies and carrying out cooperation across different institutions. These efforts provide important references for China in its top-level design of payment method, pilot project of classification system, medical service items and price dynamic adjustment, informationization and information standardization construction among public hospitals.
