OBJECTIVE:To survey utilization of traditional Chinese medicine(TCM)combined with western medicine for TCM outpatients in our hospital and to probe into pharmaceutical care in order to decrease and prevent druginduced diseases because of irrational use of drug and provide reference for safe use of TCM combined with western medicine in the clinic. METHODS:100 cases were collected from TCM department from Jan. 1 to Dec. 31 of 2009 and their prescriptions were recorded. General information in prescriptions were recorded and analyzed. RESULTS:1 200 cases of patients there were 909 patients(75.75%) using the combination therapy,136 patients(11.33%)while use of proprietary Chinese medicines,Chinese herbal medicine and western medicine. There are 655 cases of combination therapy patients(72.06%)for rational use of medicines,while 254 patients (27.94%)are not. CONCLUSION:TCM outpatients in our hospital are treated with TCM combined western medicine in general (Chinese patent medicine combined with western medicine). There is some inappropriate use of drugs so that pharmaceutical care is necessary. Drug combination is the key to pharmaceutical care.

The extra small virus (XSV) is a satellite virus associated with Macrobrachium rosenbergii nodavirus (MrNV) and its genome consists of two overlapping ORFs, CP17 and CP16. Here we demonstrate that CP16 is expressed from the second AUG of the CP17 gene and is not a proteinase cleavage result of CP17. We further expressed CP17 and several truncated CP17s (in which the N- or C-terminus or both was deleted), respectively, in Escherichia coli. Except for the recombinant plasmid CP17ΔC10, all recombinant plasmids expressed soluble protein which assembled into virus-like particles (VLPs), suggesting that the C-terminus is important for VLP formation.

Objective:To observe the influence of SBAR communication mode on the condition of patients undergoing thoracolaparoscopic combined with esophageal cancer resection.Methods:A total of 200 patients who were admitted to the Department of Gastroenterology and Oncology from October 2017 to October 2019 in Affiliated Hospital of Southwest Medical University were selected for elective thoracolaparoscopic combined with esophageal cancer resection. According to the random number method, they were divided into 100 cases in the control group and the SBAR group. The control group used conventional preoperative communication visit mode, and the SBAR group used SBAR communication mode and preoperative visit based on the control group. The following items such as the preoperative negative mentality scores, quality of life score, postoperative complications and nursing satisfaction rate of the two groups before and after nursing interventionwere compared.Results:Before the intervention, the difference of the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores of the two groups was not statistically significant ( P>0.05). After the intervention, the SAS and SDS scores of the two groups were 49.32±4.96, 55.95±5.32, 50.93±4.74, and 56.33±5.89, respectively, which were significantly reduced. The SDS and SAS scores of the SBAR group were lower than those of the control group ( t values were -9.115 and -7.142, P<0.001). The difference of the World Health Organization Brief Table on Quality of Life (WHOQOL-BREF) scores of the two groups before the intervention was not statistically significant ( P>0.05). After the intervention, the WHOQOL-BREF scores of the two groups were 12.27±1.39 vs. 9.18±1.24, 16.13±1.51 vs. 12.48±1.22, 16.13±1.95 vs. 12.71±1.28, 15.09±1.81 vs. 13.08±1.48, 18.11±1.82 vs. 13.51±1.47, 14.09±1.61 vs. 12.98±1.28. The scores of the SBAR group were higher than those of the control group ( t values were 5.397-19.662, P<0.001). The postoperative complications rate of the SBAR group was 3.00% (3/100), which was less than 18.00% (18/100) of the control group ( χ 2 value was 11.971, P<0.001). The overall satisfaction rate of patients in the SBAR group with care was 100.00% (100/100), which was higher than the 84.00% (100/100) in the control group ( χ 2 value was 17.391, P<0.001). Conclusions:In patients with esophageal cancer undergoing thoracic laparoscopy combined with esophageal cancer resection, the use of SBAR communication mode for the patient′s preoperative visit can significantly reduce the patient′s preoperative anxiety and depression negative scores and improve the patient′s quality of life, reduce the occurrence of postoperative complications, improve patient satisfaction with nursing with ideal effect.

Objective To evaluate the application of interferon-γ release assay T-SPOT.TB in diagnosis and efficacy assessment of pulmonary tuberculosis. Methods T-SPOT.TB assay was used to determine spot-forming cells (SFCs) formed by T-cells when stimulated by Mycobacterium tuberculosisspecific antigens in 55 patients with active tuberculosis,14 patients with non-tuberculosis lung diseases and 12 healthy controls. Meanwhile 20 sputum culture-positive and qualitative assay-positive pulmonary tuberculosis patients were tested with T-SPOT.TB before and at 2-month and 6-month after treatment.Kruskal-Wallis H and Mann-Whitney U test were used in group comparison.Wilcoxon test was used in comparison between pre- and post-treatment.Results The positive rate of T-SPOT.TB was significantly higher in patients with tuberculosis (85.5％,47/55 ) than that in patients with non-tuberculosis lung diseases (2/14) and the healthy controls (1/12) (x2 =40.926,P ＜0.05).The SFCs of hole A in response to ESAT-6 and hole B in response to CFP-10 in pulmonary tuberculosis group were 70.00 (27.00 -125.00) and 80.00 ( 17.00 - 180.00),respectively,which were all significantly higher than those in nontuberculosis lung diseases group and the healthy controls (x2 =35.376 and 30.485,P ＜ 0.05 ).The sensitivity,specificity,positive predictive value and negative predictive value of T-SPOT.TB in diagnosis of smear-positive tuberculosis were 88.6％,88.5％,91.2％ and 85％,while in diagnosis of sputum smearnegative tuberculosis,the sensitivity was 80％,specificity was 88.5％,positive predictive value was 84.2％ and negative predictive value was 85.2％ ( P ＞ 0.05 ).SFCs of hole A and hole B in 20 patients with sputum culture-positive and qualitative assay-positive pulmonary tuberculosis were 75.50 (41.25 -116.25 ) and 56.25 ( 105.00 -225.00) before the treatment.After 2-month antituberculosis treatment,the SFCsofhole A and hole B were 41.0 (18.0-68.75) and 72.50 (42.25- 158.75),which were significantly lower than those before treatment (Z =- 3.213 and - 3.622,P ＜ 0.05 ).Ater 6-month antituberculosis treatment,the SFCs of hole A and hole B were 25.00 (5.75 - 52.25) and 55.00 (6.25 -122.50),which were significantly lower than those before and 2-month after antituberculosis treatment (vs.before treatment:Z =- 3.921 and - 3.923,P ＜ 0.05 ; vs.2-month antituberculosis treatment:Z =- 3.926 and - 3.884,P ＜ 0.05 ).Conclusions T-SPOT.TB assay possess satisfactory sensitivity and specificity in diagnosis of tuberculosis infection,especially for sputum-negative pulmonary tuberculosis.It is also of value in monitoring antituberculosis treatment.

Objective To explore the related risk factors of severe mycoplasma pneumonia in children.Methods 86 children with mycoplasma pneumonia were selected as the observation group.At the same time,30 normal children were selected as the control group.The observation group included 33 cases of mild mycoplasma pneumo nia(A group) and 53 cases of severe mycoplasma pneumonia(B group).The clinical data of the three groups were ret rospectively analyzed,and the related risk factors of severe mycoplasma pneumonia in children were analyzed.Results The risk factors of severe mycoplasma pneumonia in children were age ＞ 5 years (x2 =28.776,P ＜ 0.05),immunoglobulin IgG(x2 =3.004,P ＜ 0.05),immunoglobulin IgM (x2 =2.147,P ＜ 0.05),immunoglobulin IgA (x2 =2.036,P ＜ 0.05),WBC (x2 =6.119,P ＜ 0.05),neutrophil percentage (x2 =8.374,P ＜ 0.05),the positive rate of CD8(x2 =11.665,P＜0.05),the positive rate of CD4(x2 =12.901,P＜0.05).Conclusion For children with risk factors of severe mycoplasma pneumonia should be early diagnosed,prevented and treated,thereby reducing the burden on patients.

Objective To investigate the effects of angiotensinⅡ(AngⅡ), Benazepril(Bena) and Losartan on proliferation and collagen synthesis of cultured rat cardiac fibroblasts(CFb) derived from SHR (CFbSHR) and WKY (CFbWKY). Methods CFb derived from 12-week-old SHR and WKY was cultured by outgrowth of tissue block. Cell proliferation of CFb was determined by direct cell counting .3H-Proline incorporation of CFb was measured after incubation with AngⅡ,Bena and Losartan. Results In serum free(0.4%FCS) medium, cell number of CFb derived from SHR and WKY were not influenced by AngⅡ(10-10mol～10-6mol)and Bena(10-9mol～10-5mol). Increased 3H-proline incorporation wa s induced by AngⅡ in a concentration dependent manner. Benazepril caused an decrease in 3H-Proline incorporation in CFb derived from SHR and WKY. The increased collagen synthesis induced by AngⅡ(10-7mol) was inhibited by Losartan((10-10mol～10-6mol） i n a concentration dependent manner. Conclusion Proliferation of CFb were not influenced by AngⅡ and Bena. Collagen synthesis of CFb was promoted by AngⅡ and inhibited by Bena. Collagen synthesis of CFb in duced by AngⅡ was inhibited by losartan.

AIM: To investigate the effect and mechanism of fluvastatin on the migration induced by platelet derived growth factor-BB (PDGF-BB) and endothelin-1 (ET-1) in cultured vascular smooth muscle cells (VSMCs). METHODS: Cultured VSMCs derived from spontaneously hypertensive rats (SHR) were used. Cell migration was determined by modified Boyden chamber assays. Intracellular free calcium ([Ca 2+ ]i) was measured with fluorescent Ca 2+ indicator Fura-2/AM. RESULTS: PDGF-BB and ET-1 significantly induced VSMCs migration, which was inhibited by pretreatment of VSMCs with fluvastatin (10 -9 -10 -5 mol/L) in a dose-dependent manner, and the peak inhibition rate of migration induced by PDGF-BB and ET-1 was over 86.67%. Fluvastatin also attenuated the increase in [Ca 2+ ]i induced by PDGF-BB and ET-1, with a peak inhibition rate of 86.76% and 65.32%, respectively. CONCLUSION: PDGF-BB and ET-1 promote migration of VSMCs from SHR.Fluvastatin may have direct inhibitory effects on cell migration induced by PDGF-BB and ET-1. The increase in [Ca 2+ ]i may acts as intracellular signaling in the migration in response to PDGF-BB and ET-1 in VSMCs.

OBJECTIVE To investigate the antimicrobial-resistant genes in meticillin-resistant Staphylococcus aureus(MRSA).METHODS Forty strains of MRSA were clinically isolated.Nine kinds of antimicrobial-resistant genes were analyzed by polymerase chain reaction(PCR).RESULTS The positive rates of mecA,aac(6′)/aph(2′)and tetM were all 100.0%.The positive rates of ermA/B/C,aph(3′)-Ⅲ,qacA/B,PVL and ant(4′,4″) were 82.5%,67.5%,45.0%,10.0% and 2.5%,respectively.CONCLUSIONS There are higher positive percentages of relevant resistance genes in MRSA isolates clinically.MRSA can induce clone transmition in hospital which should pay,and attention to the disinfection and isolation.
