Objective:This paper aims to explore the relationship between the residents’ health and economic de-velopment to provide a scientific basis which will promote the coordinated economy and health development. Methods:Adopting the entropy method, we could calculate the comprehensive health evaluation index. In combining the co-inte-gration and error correction models, we could analyze the long-term and short-term relationships between our country residents’ level of health since 2000 and the national macro-economic development information. The Granger causality test served as a good method used in testing the casual relationships. Results: The health and economic development has a co-integration relationship which is -0. 6216 in the short-term correction. The economic development extent is the Granger cause of residents’ health status. Conclusion:There is not only a long-term equilibrium, but also a short-term relationship between the residents’ health and economic development in our country. The economic growth pro-motes residents’ health status while the promotion of residents’ health to economic growth is not obvious.

Objective To improve the understanding of bacteria bolt in upper urinary tract,and to investigate its diagnosis and treatment.Methods The clinical data of 11 cases with bacteria bolt in upper urinary tract were reviewed retrospectively.The clinical manifestation and treatment were summarized.Results Infection and obstruction were the clinical manifestation.Two-stage treatment was provided.Ureteral stent was indwelled in two cases,and percutaneous nephrostomy was provided at the first stage in the other 9 cases.Then the bacteria bolt was taken by ureteroscopy (1 case) or by percutaneous nephrostomy (10 cases) when the condition improved.The second stage operation took 37 min on average (ranged from 20 to 55).Estimated blood loss 60 ml on average (ranged from 10 to 200 ml).Hemoglobin decreased 5.1 g/L (3-11 g/L) 48 hours after operation in the 10 cases underwent percutaneous nephrostomy.Bolt-free rate was 100％.There was no infectious shock occurred.No relapse was observed during the 16 months of follow-up.Conclusions Bacteria bolt in upper urinary tract is not common.Infection and obstruction are its manifestation.Two-stage treatment is safe and effective.

This study aims to investigate the virological impact of the stalk region and cysteine (C) in neuraminidase (NA) of influenza A/Anhui/1/05 (H5N1) and A/Ohio/07/2009 (H1N1) viruses. The NA of A/ Anhui/1/05 (H5N1), defined as AH N1, lacked 20 amino acids (including C, defined as s20) as compared with NA of A/Ohio/07/2009 (H1N1) (defined as 09N1). We deleted s20 of 09N1 to construct 09N1-s20, and inserted s20 into AH N1 to construct AH N1+s20. To investigate the impact of C on the biological function of NA, we deleted C in 09N1 to construct 09N1-C and inserted C into AH N1 to construct AH N1-C. The pseudo-type viral particle (pp) system was used to evaluate the impact of these mutants on virology. The combination of 09N1-C and 09H1 (defined as 09H1::09N1-C) showed an infectivity 8 times that of the wild type 09H1::09N1, while the infectivity of the combination of AH N1+C and AH H5 (defined as AH H5::AH N1+C) was much lower than that of the wild type AH H5::AH N1. The infectivity of the combination of 09N1-s20 and 09H1 (defined as 09H1::09N1-s20) was 4 times that of the wild type 09H1::09N1; the infectivity of the combination of AH N1+s20 and AH H5 (defined as AH H5:: AH N1+s20) was 1/7 that of the wild type AH H5::AH N1. The co-existence of 09N1-C and AH H5 displayed 6 times the infectivity of AH H5::09N1, while the infectivity of 09H1::AH N1+C was very low. Multimer analysis showed that in the wild type 09N1, the forms of NA were dimer > tetramer > monomer; the major component of NA in 09N1-C was monomer; in 09N1-s20, the forms of NA were monomer > dimer. AH N1 was mainly composed of monomer; in AH N1+s20, the forms of NA were dimer > monomer > tetramer; in AH N1+C, the forms of NA were dimer > tetramer. Deletion of C or s20 from 09N1 did not change the expression of NA. The study suggested that deletion of C from the stalk region of NA in A/Ohio/07/2009 (H1N1) increases infectivity. Insertion of C into NA's stalk region of A/ Anhui/1/05 (H5N1) significantly decreases infectivity. Cysteine deletion in the stalk region is important for the infectivity of A/Anhui/1/05 (H5N1) and A/Ohio/07/2009 (H1N1). It may interfere with the infectivity via changes in NA polymerization.

OBJECTIVE To evaluate the difference of efficacy of sublingual immunotherapy on different age patients with allergic rhinitis. METHODS 229 patients with dermatophagoides farina drops allergic rhinitis who have finished SLIT at least 2 years were enrolled and analyzed by retrospective analysis. All patients were divided into different age groups: pre-adolescence(n=107), adolescence(n=53), adulthood(n=69). Indexes for therapeutic effects of SLIT visual analogue scale(VAS) score, rhinitis symptom scores, medication scoreintra- and inter groups were assessed during different stage of treatment(3 months, 1 year and 2 years). Data were analyzed with SPSS 19.0 software. RESULTS Compared with prior treatment, after the SLIT for 3 months, 1 year, 2 years, VAS scores, rhinitis symptom scores, medication scoresof all the patients with allergic rhinitis are significantly decreased; Differences of rhinitis symptom scores(H=0.844, 4.153, 2.669, P>0.05), VAS score(H=1.356, 3.720, 0.313, P >0.05), medication scores(H=1.044, 5.841, 3.399, P>0.05) between groups had no statistical significance at different stage after treatment(3 months, 1 year and 2 years); The differences between 2 years and 1 year of SLIT treatment showed statistical significance in the VAS scores(Z=1.635, P =1.635). CONCLUSION SLIT with dust mites drops had good curative effect and security in patients with allergic rhinitis, which hadno obvious difference between different age groups.

Objective To explore genes expression of adiponectin receptors during differentiation of SW872 preadipocytes. Met-(hods) SW872 preadipocytes were cultured in vitro and induced to differentiate by 0.6 mmol/L oleic acid. During the progress of diffe-(rentiation), the morphological changes of SW872 cells were observed and the differentiation rate was assayed by oil-red O staining. Adiponectin receptors mRNA was measured by reverse transcription-polymerase chain reaction during differentiation of SW872 preadipocytes. Results 1.After stimulated by 0.6 mmol/L oleic acid for 72 hours, almost all SW872 cells were differentiated,and there were lots of fat droplets in the cells.2.There were adiponectin receptors genes expressions in SW872 preadipocytes.After 72 hours,and the levels of adiponectin receptor(AdipoR) 1 mRNA and AdipoR 2 mRNA were markedly increased up to 2.54 and 4.09 times,respectively. Conclusion There are AdipoR1 and AdipoR2 genes expressions in fat cells and the expressions are differentiation-dependent.

Objective To study the effect of oleic acid on the differentiation of SW872 preadipocytes.Methods SW872 prea-(dipocytes) were cultured and induced to differentiate by 0.6 mmol/L oleic acid in vitro.After 24 h,48 h and 72 h of differentiation,the morphological changes of SW872 preadipocytes were observed and the differentiation rate was assayed by oil-red O staining.In addition,triglyceride(TG) mass was detected by chemical colorimetry methods.During the differentiation of SW872 preadipocytes,transcription factors including peroxisome proliferator activated receptor-?_2(PPAR-?_2) and CAAT/enhancer binding protein-?(C/EBP-?)(mRNA) were also measured by reverse transcription-polymerase chain reaction(RT-PCR).Results 1.SW872 preadipocytes were fibroblastic and had no obvious fat droplet in cytoplasm.However,when stimulated for 72 hby 0.6 mmol/L oleic acid,SW872 preadipocytes became more bigger and rounder and differentiated into mature adipocytes with lots of fat droplets in the cells.2.Compared with that of predifferentiation,the concentration of TG mass increased by 14 folds after 72-hour differentiation(P

OBJECTIVETo compare the therapeutic effects between anatomical locked plate combined with coracoclavicular ligament reconstruction and clavicular hook plate for treatment of distal clavicle fracture of Neer type II b.

METHODSFrom August 2010 to August 2013, 42 patients with Neer II b distal clavicle fractures were randomly divided into two groups as group A and group B. In group A, there were 22 cases including 14 males and 8 females with an average age of (44.2±11.6) years old. In group B, there were 20 cases including 11 males and 9 females with an average of (45.6±12.4) years old. The patients of group A were treated with anatomical locked plate combined with coracoclavicular ligament reconstruction,the patients of group B were treated with hook plate. All fractures were fresh, the time between injuries and operation was 24 hours to 7 days (mean,72 h). General information between the two groups was comparable before operation(P>0.05). Postoperative radiographic were followed up to observe the fracture healing,internal fixation and to measure coracoclavicular distance of two groups. Shoulder function after operation was evaluated by Constant-Murley score system.

RESULTSAll patients were followed up with an average of 16.8 months (ranging 12 to 24 months). There was no nonunion,infection and other complications between two groups. The clavicular stress fracture occurred in 1 clavicular hook patient at 6 months after the operation. According to the Constant-Murley score system, that the scores of group A were 90.6±6.2, 91.8±4.8, 94.7±3.6 and 97.8±1.2 at 1st, 3rd, 6 month and last follow-up after operation were higher than those of group B 74.8±3.4, 78.4±4.4, 82.2±2.8 and 94.6±3.6 (P 0.05). The fracture healing time of group A (21.6±2.2) weeks was shorter than that of group B (25.8±2.5) weeks (P 0.05). There were no statistically significant differences between two groups in coracoclavicular distance at last follow-up (P>0.05).

CONCLUSIONThe anatomical locked plate combined with coracoclavicular ligament reconstruction need not expose shoulder and can reduce the incidence of postoperative pain and limited activity of shoulder, with fewer complication, it is advantageous to the shoulder joint function early recovery.

Objective To explore the prevalence,awareness and risk factors of chronic kidney disease (CKD) in general adult population of Anhui province,China. Methods A total of 3800 residents (older than 18 years) from Anhui province were randomly selected using a stratified,multi-stage sampling.All the residents were interviewed and tested for urinary albumin to creatinine ratio (abnormal:≥30 mg/g) and reduced estimated GFR [abnormal:＜60 ml·min1·(1.73 m2)-1]. The associations of CKD with demographic characteristics, healthy charactefistcs (hypertension,diabetes and hyperuricemia) were examined. Results Eligible data of 3374 subjects were enrolled in the study.After the adjustment of age and gender component,the prevalence of albuminuria was 9.8％ (95％CI 8.8％-10.9％),and reduced eGFR was 2.1％ (95％ CI 1.7％-2.7％).Approximately 10.4％(95％CI 9.4％-11.5％)subjects had at least one indicator of kidney damage.The awareness rate of CKD was 6.5％.Female,age,hypertension,diabetes mellitus,and hyperuricemia were independently associated with CKD.While obesity,hyperlipdemia.smoking and alcohol drinking were not associated with the prevalence of CKD. Conclusions The prevalace of chronic kidney disease is 10.4％ and the awareness rate is 6.5％ in general adult population of Anhui province.Independent risk factors associated with CKD are female,age,hypersion,diabetes mellitus and hyeruricemia.

Objective To investigate the regional left ventricular function after mitral valve replacement with and without chordal preservation by strain rate imaging. Methods A total of 55 patients undergoing mitral valve replacement were enrolled. Twenty underwent complete excision of the subvalvular apparatus (group A), 20 preserved the posterior chordopapillary apparatus only (group B) and the other 15 underwent total chordal preservation (group C). Systolic peak strain rate (SRs) were measured preoperatively, at 7-10 days and 3 months after operation. Results Before operation, SRs had no differences between different segments of the left ventricular in each group (F=0.37, 0.74, 0.90, all P>0.05). At 7-10 days after operation, SRs in the most segments of left ventricular were signiifcantly lower than those of before operation (F=3.91, 8.12, 7.57, all P<0.05). At 3 months after operation, SRs in some segments of left ventricular were signiifcantly higher than those of preoperation in each group (t=2.12, 3.19, 3.25, 2.08, 2.78, 4.79, 2.81, 2.58, 2.87, 1.60, 0.34, 1.04, 0.73, 0.70, 1.68, all P<0.05). SRs had no signiifcant differences between each segment of left ventricular in group C (F=1.76, P>0.05). By contrast, SRs in some segments of left ventricular were different from those of other segments in group A and group B (F=17.8, 8.52, both P<0.05). Conclusion Comparing to conventional mitral valve replacement and mitral valve replacement with preservation of posterior subvalvular apparatus, mitral valve replacement with preservation of total subvalvular apparatus makes the papiltary function preserved completely, which are beneifcial for the motor coordination of left ventricular wall and the recovery of regional left ventricular function.
