Objective To explore the spatial distribution of Keshan disease(KD) in the 15 surveillance provinces(municipalities,autonomous regions ) and to provide the basis for the development of prevention and control strategies.MethodsBased on the KD surveillance data of the 15 provinces in 2007,five indicators were selected.Moreover,a comprehensive indicator score to assess KD of different areas was made through the method of principle components analysis,which was applied for regionalization of the KD areas by the subsection method of standard deviation in whole China.The KD areas were divided into mild,moderate and severe endemic areas.The spatial distribution feature of the comprehensive indicator score was displayed by using geographic information system (GIS).ResultsThe three principal components contained 88.123％ information of all the selected indicators,the first principal component had a close relationship with total KD detection rate,chronic KD detection rate and latent KD detection rate; the second principal component had a close relationship with the threatened number in KD areas,and the third principal component had a close relationship with new KD detection rate; the comprehensive indicator indicates that Gansu,Jilin,Heilongjiang,Hebei,and Liaoning provinces were serious prevalent KD areas; Inner Mongolia,Shandong,Hubei,Sichuang provinces (autonomous region) were moderate prevalent KD areas,and Shanxi,Shaanxi,Yunnan,Henan,Guizhou,Chongqing provinces(municipality)were mild prevalent KD areas.Conclusions The introduction of the GIS to Keshan disease monitoring,provides a convenient and direct method to observe the spatial distribution of the disease,and the results point out the key areas for further KD surveillance according to local conditions.

Objective:To provide reference for clinical pharmacists through pharmaceutical care for patients with hyponatremia en-cephalopathy caused by pituitrin. Methods: Clinical pharmacists provided pharmaceutical care for one patient with hyponatremia en-cephalopathy caused by pituitrin. It was suggested by clinical pharmacists that 3% hypertonic saline and 20% mannitol be used in the patient with sodium ions and renal function monitoring. The patient was also told to increase salt in diets and limit water uptake. Re-sults:The ion levels of the patient returned to normal after the pharmaceutical care. Conclusion:Clinical pharmacists play an impor-tant role in the prevention and treatment of hyponatremia encephalopathy caused by pituitrin.

Objective: To evaluate the preliminary effect for serum albumin (ALB) level in patients with chronic heart failure (CHF) treated by cardiac resynchronization (CRT).
Methods: A total of 54 CHF patients treated in our hospital from 2009-01 to 2013-12 were studied. The patients were divided into 2 groups: CRT group and Control group, in which the patients were treated by medication. n=27 in each group. The blood test of biochemistry, 24 hour dynamic ECG monitoring with QRS duration, echocardiography, ALB level, heart rate (HR), left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) were recorded at admission as baseline information, and the above examinations were repeated 2 to 3 times during 6-15 months of follow-up period.
Results: The age, gender and baseline information were similar between 2 groups. Compared with admission, during followed-up period, CRT group had increased ALB, LVEF, P<0.05, decreased HR, P<0.001, shorter QRS duration, P<0.001 and LVED remained similar;while Control group had decreased ALB, P<0.05 and LVEF, LVED, QRS duration, HR remained similar. Logistic regression analysis indicated that in CRT group, with adjusted LVEF, QRS duration and ALB, serum ALB level was the most relevant indicator for CRT efifcacy, P<0.01.
Conclusion: CRT could improve the cardiac function and increase ALB in CHF patients, therefore serum ALB level might be related to CRT efifcacy at certain degree.

Objective To compare the clinical therapeutic efficacy of excision and primary suture after the hydrogen peroxide and methylene blue treatment, and Limberg transposition flap for the treatment of pilonidal sinus. Methods The clinical data of 55 patients with sacrococcygeal pilonidal sinus were analyzed retrospectively. Thirty-six patients were treated by excision and primary suture after the hydrogen peroxide and methylene blue treatment (suture group), and 19 patients were treated by Limberg transposition flap (flap group). The operation time, length of hospital stay, incision healing time, incidence of complications and recurrence rate were compared between 2 groups. Results There were no significant differences in the length of hospital stay, incision healing time, incidence of complications and recurrence rate between 2 groups (P>0.05). The operation time in suture group was significantly shorter than that in flap group: (51.25 ± 7.02) min vs. (71.42 ± 12.29) min, and there was statistical difference (P = 0.000). Conclusions Excision and primary suture after the hydrogen peroxide and methylene blue treatment is a good method for the treatment of pilonidal sinus. The operation time is short. It is easy to operate, and could achieve good results.

A total of 115 patients with Hoshimoto thyroiditis were classified under 2 groups: one group being treated with selenium and L-throxine (L-T4) and other group with L-T4 alone.All patients were followed up for 3 months.In the selenium treated group thyroid peroxidase antibody level was decreased in 33 patients (56%) and thyroglobulin antibody level was decreased in cases.

Aim To observe the modulation of adenosine triphosphate (ATP) on motility of isolated gastric smooth muscle from rat.Methods Longitudinal and circular muscle strips of rat gastric body and antrum were prepared, and the effects of ATP (0.1, 1,10,100 ?mol?L~-1 and 1 mmol?L~-1 ) on the motility of the strips were investigated. Results ATP induced a small relaxation followed by an obvious spasm in longi- tudinal muscle strips of the gastric body; when tone was raised by KCl, ATP induced a larger relaxation followed by a smaller spasm.ATP only produced contraction in circular muscle strips of the gastric body.Low concentration of ATP inhibited the contractile amplitude of the antral longitudinal strips, at the same time increased the frequency of the contraction apparently; when tone was raised by KCl, ATP produced a concentration-related relaxation.Low concentration of ATP firstly enhanced and then inhibited contractile amplitude of antral circular musle strips, while high concentration of ATP fully inhibited the motility. Conclusion We firstly reported the obvious effects of ATP on longitudinal and circular strips of rat gastric body and antrum. The effects of ATP on the four preparations were different from each other, suggesting that ATP plays an important modulatory role on motility of gastric smooth muscle of rats.

Objective To investigate the effect of probucol on Sertoli cell injury induced by oxygen-glucose deprivation/reoxygenation(OGD/R)and mechanism. Methods Primary Sertoli cells treated with oxygen glucose deprivation for 2 h and reoxygenation for 3 h were modeled. We incubated Sertoli cells with probucol in a concentration of 5,10,and 20 μmol/L from reoxygenation to the end. The cell viability was evaluated using Cell Proliferation Assay kit. ROS production was observed by flow cytometry. The levels of MDA ,iron and GSH or the activity of glutathione-dependent peroxidase were measured by Assay Kit. Results The ferroptosis inhibitors pre-vented cell death(P < 0.01). The cell death rate was decreased by probucol in time- and dose-dependent manner (P < 0.01). Meanwhile, probucol caused increase of ROS,MDA,GSH content and GPXs activity(P < 0.05). Conclusion Probucol protects Sertoli cells from OGD/R damage via inhibiting lipid peroxidation-mediated ferroptosis.

Objective To study the biomechanical strength of calcium phoshphate cement (CPC) in fixating distal radial fractures. Methods A total of 18 human distal radius fracture models were made and randomly divided into three groups: fixed with Kirschner wire (Kirschner group), CPC (CPC group) or CPC combined with Kirschner wire (combination group). Compression test was performed to measure compression rigidity and rotational angle of distal fragment at 100 N and anticompression strength and maximum compression strength at 2 mm displacement. Results Compression rigidity, distal fragment rotation angle in coronal or sagittal plate had no significant statistical difference at 100 N of compression in three groups. Compression strength at 2 mm displacement in CPC group (average 375 N) and combination group (average 386 N) exceeded that in Kirschner group (average 116 N), with significantly statistical difference (P

Objective To understand the etiology of acute hepatitis B (AHB) in adults and investigate the mechanisms of hepatic injury and viral clearance in AHB. Methods One hundred and twenty adult AHB patients were enrolled. Epidemiological and clinical data were collected from the case history records or face-to-face inquiry, and serum samples were collected during hospitalization and follow-up. To observe dynamic patterns of AHB etiology, the markers of hepatitis B virus (HBV) were detected by enzyme-linked immunosorbent assay (ELISA); the level of HBV DNA and HBV genotype were determined by real-time polymerase chain reaction (PCR). Enumeration data were analyzed by non-parametric rank sum test. Comparison between groups was done by t test and that between rates of samples was done by Pearson χ2 test. Results Serum HBV DNA was positive in 48.33% of patients at the time of diagnosis with mean level of 9.84×04 copy/mL, and became undetectable after 12.5 days on average. The median levels of serum alanine aminotransferase (ALT) were 1600 U/L and 1490 U/L in HBV DNA positive and negative groups, respectively (z=-0. 678, P=0. 498). However, the mean levels of serum ALT were (2058±123) U/L and (1393±139) U/L in groups of HBV DNA<1×104 copy/mL and>1×104 copy/mL, respectively, which was significantly different (t=-2.17, P=0. 049). Genotype B accounted for 52.5%, genotype C 42.5 and genotype B and C mixed type 5.0% in 58 patients with HBV DNA positive. Eight patterns of serum HBV markers were presented at first visiting. HBsAg(+), HBeAg(+), anti-HBc(+), anti-HBc IgM(+) and HBsAg(+), anti-HBe(+), anti-HBc(+), anti-HBc IgM(+) were the most common patterns, which accounted for 38.3% and 30.0%, respectively. The dynamic patterns of serum HBV markers of 28 AFIB patients were prospectively followed up. The rate of serum FIBsAg loss was 100. 0% and the median time of negative-conversion was 3 weeks. The cumulative positive rate of anti-HBs was 85.7% after 52 weeks of follow-up. The rate of serum HBeAg loss was 100.0%. HBeAg was negative in 53.6% of patients at first visiting and the rest of patients achieved negative within 4 weeks after onset. The positive rate of anti-HBe was 82.1% during 52 weeks of follow-up. Total anti-HBc (including IgG and IgM) was keeping positive in all patients within 52 weeks, and the negative rate of anti-HBc IgM was 39. 3% after followed up for 52 weeks. Conclusions Rapid HBV clearance andserum HBV marker conversion are significantly different between AHB and chronic hepatitis B.
