Objective To construct health examination system based on network to satisfy the growing demand for businesses management. Methods Through interacting on the system interface with LIS. The use of diagnostic expressions, templates and default values speeded up medical data entry and deposit in scan mode to non -digital medical images. Results The software of health examination information system was developed and the work flow of health examination was reconstructed. Conclusion The physical examination information system can greatly reduce the workload of repeated transcription and entering, and enhance the efficiency of health examination management.

OBJECTIVETo improve the respiratory isolation policy for patients with suspected pulmonary tuberculosis (TB).

METHODSAll consecutive patients with suspicion of having pulmonary TB when seeking health care at the County TB dispensary of the Center of Disease Control and Prevention received face to face interview.

RESULTSA Classification model was constructed with a sensitivity of 90.9% and specificity of 90.2%, while predictive factors of culture-proven pulmonary TB among smear negativecases were soakage in Chest X-ray exam (77.0% vs. 4.4%; P<0.0001), bilateral lung's abnormal (1.6% vs. 19.4%; P<0.0001) and reaction of tuberculin skin testing (0.0% vs. 2.6%; P=0.014).

CONCLUSIONSoakage, bilateral lung's abnormal and positive reaction of tuberculin skin testing were important predictors to prognosticate culture positive diagnosis. The model had been proved to have promising sensitivity and specificity in the rural population covered by NTP-DOTs.

Objective To observe the effect of the yang-warming and fluid retention-resolving mothed on neuroendocrine and inflammatory factors in chronic heart failure (CHF) rats. Methods A total of 50 healthy adult male SD rats were randomly divided into blank group (10), CHF group (40). In CHF group, the rat model of chronic heart failure was replicated by intraperitoneal injection of adriamycin (ADR). After the completion of the model making, doppler echocardiography was used to determine the cardiac function of rats. There rats were randomly divided into the model group, the yang-warming and fluid retention-resolving group, the Xuefu-Zhuyu group and the captopril group. After continuous administration for 28 d and 2 h after the last dose, the HE staining was used to observe the pathological morphological changes of myocardium in each group. The levels of AngⅡ, TNF-α and IL-6 in serum were by ELISA. Results Compared with model group, the content of serum AngⅡ(294.33 ± 25.45 pg/ml, 265.86 ± 27.80 pg/ml, 301.87 ± 41.67 pg/ml vs. 615.44 ± 22.31 pg/ml), TNF-α(117.15 ± 11.33 pg/ml, 114.02 ± 11.57 pg/ml, 133.35 ± 34.80 pg/ml vs. 185.72 ± 36.53 pg/ml), IL-6 (23.97 ± 4.77 pg/ml, 27.61 ± 7.01 pg/ml, 28.38 ± 5.78 pg/ml vs. 58.45 ± 6.36 pg/ml) in the yang-warming and fluid retention-resolving group, Xuefu-Zhuyu group and captopril group significantly decreased (P<0.01 or P<0.05). Compared with Xuefu-Zhuyu group, the content of serumAngⅡ (301.87 ± 41.67 pg/ml vs. 265.86 ± 27.80 pg/ml) in the captopril group significantly increased (P<0.05). Conclusions The yang-warming and fluid retention-resolving mothed can reduce early CHF rats through reducing the serum TNF-α, Ang and ILⅡ -6 content, which could be one of the mechanism of action of the treatment of CHF.

Objective To investigate the therapeutic effect of Dange Jiecheng decoction on a rat model of alcoholic liver disease (ALD) and the anti-oxidative stress mechanism of Dange Jiecheng decoction. Methods A total of 96 Sprague-Dawley rats were randomly divided into blank group with 13 rats and ALD group with 83 rats, and the rats in the ALD group were given liquor by gavage to establish a model of ALD. Then the ALD group was randomly divided into model group, high-dose Dange Jiecheng decoction group (24 g/kg), low-dose Dange Jiecheng decoction group (6 g/kg), and Yiganling tablet group (21 mg/kg), with 17 rats in each group. The rats in the blank group and the model group were given normal saline by gavage, and those in the other groups were given corresponding drugs by gavage, for 4 consecutive weeks. HE staining was used to observe the pathological changes of liver tissue; Western blot was used to measure the contents of Kelch-like ECH-associated protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) in liver tissue; quantitative real-time PCR was used to measure the mRNA expression levels of Keap1 and HO-1 in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the blank group, the model group had disordered arrangement of hepatocytes with necrosis, massive inflammatory cell infiltration, and a large number of lipid droplet vacuoles, significant increases in the protein and mRNA expression levels of Keap1 ( P < 0.05), and significant reductions in the protein expression levels of Nrf2 and HO-1 and the mRNA expression level of HO-1 ( P < 0.05). Compared with the model group, the high- and low-dose Dange Jiecheng decoction groups and the Yiganling tablet group had ordered arrangement of hepatocytes, reductions in hepatocyte necrosis and inflammatory cells, and occasional lipid droplet vacuoles, as well as significant reductions in the protein and mRNA expression levels of Keap1 ( P < 0.05) and significant increases in the protein expression levels of Nrf2 and HO-1 and the mRNA expression level of HO-1 ( P < 0.05). Conclusion By regulating the Keap1/Nrf2 signaling pathway, Dange Jiecheng decoction can promote the nuclear import of Nrf2, upregulate the expression of HO-1, and alleviate oxidative stress response, thereby exerting a protective effect on ALD rats.

The ligation of dorsal venous complex (DVC) is a very important procedure during laparoscopic radical prostatectomy (LRP). Inaccurate DVC ligation may lead to severe bleeding or postoperative incontinence. We, therefore, designed the DVC pretightening technique to facilitate this procedure. The 32 involved patients with localized prostate cancer underwent LRP between July 2017 and October 2018. All of the patients received DVC pretightening technique. A laparoscopic intestinal clamp was used to narrow and strain DVC. The needle passage was limited between the bone and clamp. The ligation time, DVC-related blood loss, and continence data were recorded. The ligation of DVC in 32 patients was performed with DVC pretightening technique. Every suture was completed with one attempt. The mean ligation time was 2.7 ± 1.0 min. The DVC-related blood loss was 2.0 ± 1.3 ml. The 3-month continence rate was 81.3% (26/32). Positive margin rate was 9.4% (3/32). In conclusion, the DVC pretightening technique simplified the ligation of DVC during LRP. It is a safe and reliable technique. However, large-sample randomized controlled trials are still required to confirm the advantage of the new method in improving mean ligation time, DVC-related blood loss, continence rate, and positive margin rate.

Objective: To clarify the genotype of varicella-zoster virus (VZV) in Jilin province in 2017, and to discriminate between vaccine strain and wild-type strain. Methods: Vesicle fluid and throat swab samples were collected from 10 individuals with suspected VZV in Jilin province from January to March of 2017. Real-time fluorescent quantitative PCR was used to detect viral nucleic acid. Specific regions of ORF22, ORF38 and ORF62 of VZV were amplified by PCR. Viral genotype was determined by five SNPs of ORF 22 and vaccine strain or wild-type strain was distinguished by four SNPs of ORF 38 and ORF 62. The results were analyzed with MEGA5 and BioEdit software, using the VZV reference strain sequences from GenBank. Results: VZV-positive strains were detected in 10 samples, all belonged to Clade 2. There was a synonymous mutation (C→T) in position 38 048 of JL17-7 strain. The nucleotide homology of ORF22 showed that all 10 samples were on the same branch with the Clade 2 referenced strains. Compared with Clade 2 referenced strains, the homology of nucleotide and amino acid for all 10 samples were 99.5%-100% and 99.3%-100%, respectively. The four specific SNPs of ORF38 and ORF62 in 10 samples were A-T-T-T, which were consistent with wild-type strain. Conclusions This study reveals that the VZV strains circulating in Jilin province in 2017 were all wild-type strains belonging to Clade 2.
