Objective To analyze the prevalent feature and variant tendency of Scrub Typhus in Guangdong Province from 2006 to 2012, and provide a basis of strategy and measure on prevention and protection of Scrub Typhus. Methods Clinical information of all individual cases was gained from China Information System for Disease Control and Prevention. Cochran-Armitage trend χ2 test was used to describe the variance of Scrub Typhus incidence and the clinical cases of 2013 were predicted by autoregressive integrated moving average (ARIMA) model, while descriptive epidemiological analysis was adopted to describe the endemic distribution, seasonal characteristics and population distribution of Scrub Typhus. Results A total of 8 163 Scrub typhus cases were reported in Guangdong Province from 2006 to 2012. Annual mean incidence of the disease was 1.15/100 000 with the incidence showing an upward tendency (χ2 = 3 191.976, P < 0.01). There were 14 dead clinical cases reported with a fatality rate to be 1.72‰(14/8 163). Totally 3 166 people were predicted to infect Scrub Typhus in 2013 by ARIMA model. The disease was prevalent from the end of May to early October and the peak time was in late August (Z = 2 303.71, P < 0.01). The top five cities developed Scrub Typhus were Zhaoqing, Guangzhou, Yunfu, Shaoguan and Qingyuan. Male-female ratio was 1.00 ∶ 1.08 in all reported cases in which 52.78%(4 309/8 163) of them aged from 40 to 65 years old and 59.30%(4 841/8 163) of them were farmers. Conclusions The incidence of Scrub Typhus is rising in Guangdong Province, with the prevalent peak in summer and autumn, and rural populations are at high risk. The most effective preventions are strengthening health education , enhancing individual protection and protecting key populations in special districts.

Objective To establish a method of HPLC assay for determining stilbene glucoside in Zishen Ningshen Pills(ZNP),and to study the influence factors on the content of stilbene glucoside in the process of preparation.Methods HPLC was used for the determination of stilbene glucoside in ZNP.Through simulation the process of preparation,the stilbene glucoside content in the intermediate products was determined by HPLC,and its retention rate and metastasis rate were also investigated.Results The resolution and the linearity of stilbene glucoside were fine,the average recoveries being 98 % ～ 102 %.The retention rate of stilbene glucoside in the drying powder was 60.3 %,lower than that in the original medicinal powder.Conclusion The quantitative method for determining the ingredients in ZNP is simple,feasible and reproducible,and is beneficial for quality control of ZNP.The drying process under normal pressure is the main influence factors of the decrease of stilbene glucoside content,and the decompression drying can be taken into account to take the place of the atmospheric drying.

Objecfive To detect the functional repair of metanephric mesenchymal cells (MMCs) transplantation in adriamycin (ADR)-induced glomerulopathy rats. Methods A total of 90 Sprague-Dawley female rats were randomly divided into three groups:ADR group (n=40,rats were injected via the tail vein with O.25 mg ADR/100 g body weight on days 1 and 21),ADR- MMCs group(n=40,rats were injected via the tail vein with 5×10~6-7×10~6 MMCs 8 weeks after the second ADR administration),control(n=10).All the rats were scarified 8 weeks after MMCsinjection.Pathology and collagen IV expression in renal tissue were examined.Moreover,matrix metalloproteinases 2 (MMP-2) and matrix metallopmteinases 9 (MMP-9) expression in the renal tissue were also detected with immunohistochemistry,and quantity analysis of protein and gene was further demonstrated with Westem blot and RT-PCR analysis,respectively. Results There were no significant differences in tubulointerstitial injury score and glomerulosclerosis degree between ADR group and ADR-MMCs group(P>0.05).Compared with ADR group,collagen Ⅳ and MMP-2 expression decreased, MMP-9 expression incrased in renal tissue of ADR-MMCs group, and the difference was significant (P<0.05). Conclusion MMCs transplantation may have potentially therapeutic effect on renal tissue fibrosis of adriamyein-induced glomerulopathy in rats, and the signaling pathways of MMPs appear to be involved in these processes.

Objective To investigate the effect and possible mechanism of bone marrow stem cell mobilized by stem cell factor (SCF) with granulocyte colony-stimulating factor(G-CSF)on renal peritubular capillary, fibrosis and renal function in unilateral ureteral obstruction (UUO) rats. Methods One hundred and twenty eight healthy male Wistar rats were randomly divided into four groups: Sham group, SCF-G group, UUO group and UUO+SCF-G group. Eight rats of each group were randomly selected and killed on the 5th, 14th, 21st and 28th day. Serum creatinine, CD34 positive cells and factor Ⅷ positive cells in renal interstitium, histopathologic lesion scores of interstitial fibrosis and interstitial pathology in kidney were measured. The mRNA expression of vascular endothelial growth factor (VEGF). and thrombospondin-1 (TSP-1) in the renal cortex was detected. Results (1) The renal interstitial fibrosis anti the loss of peritubular capillary were observed in UUO group after two weeks. (2) The number of bone marrow stem cells homing to renal interstitium in UUO +SCF-G group was significantly higher than that in UUO and Sham groups (P<0.05). (3) The loss of peritubular capillary in UUO+SCF-G group appeared later than that in UUO group (P<0.05). (4) The interstitial fibrosis and tubule injury was milder in UUO+SCF-G group than that in UUO group (P<0.05). (5) The decrease of VEGF mRNA expression of renal cortex in UUO +SCF-G group was seen later than that in UUO group. VEGF mRNA expression in UUO+SCF-G group was higher than that in UUO group. (6) The increase of TSP-1 mRNA expression of renal cortex in UUO+SCF-G group was seen later than that in UUO group. TSP-1 mRNA expression in UUO+SCF-G group was lower than that in UUO group (P<0.05). (7) In UUO and UUO+SCF-G groups, peritubular capillary index was negatively correlated with serum creatinine, interstitial fibrosis and interstitial lesion scores. VEGF mRNA expression of renal cortex was positively correlated with peritubular capillary index, and TSP-1 mRNA expression of renal cortex was positively correlated with peritubular capillary index. Conclusions (1)The loss of peritubular capillary is found in UUO group, and is correlated with interstitial fibrosis and interstitial lesion. (2) Application of SCF with G-CSF can effectively motivate stem cells to injured renal tissue, contribute to decrease the loss of peritubular capillary, lessen interstitial fibrosis and interstitial lesion, and ameliorate renal function. (3) Application of SCF with G-CSF can up-regulate VEGF mRNA expression and down-regulate TSP-1 mRNA expression, which may contribute to promote the repair of endothelial cells and protect peritubular capillary.

Objective To investigatethe quality of life of patients with oral cancer in different period in a hospital, and to explore the impact of patients' psychological status on their quality of life. Methods 50 cases of oral cancer patients in our hospital were investigated in this study by Convenience sampling method. The scale of the hospital anxiety and Depression Scale (HADS, the Japanese version), the quality of life of cancer patients were measured by the scale (FACT-G); the functional evaluation of tumor therapy- head and neck questionnaire (FACT-H&N). Results The comparison of HADS score between patients before and after surgery showed that the improvement of mental status was not obvious in the postoperative patients.The scores of HADS between patients before surgery and after hospital showed that the improvement of mental status was obvious (t=-2.809, P=0.01; t=-3.828, P=0.003). There were significant differences in HADS anxiety and depression-related factors between different periods (F=7.644,P=0.001;F=6.442,P=0.002);Before surgery,patients with low anxiety and depression had higher scores in both emotional and physical functional dimensions, and the difference between the two groups was statistically significant (t=7.882,5.847,6.870,7.262, P<0.05 or 0.01). The scores of the two groups were higher in the whole life quality dimension after surgery,and the difference between the two groups was statistically significant(t=3.640-7.931,P<0.01 or 0.01).There were significant differences in body function and psychological function scores between different periods(F=8.569, P=0.000; F=10.250, P=0.003). Conclusions Oral cancer patients have a higher level of anxiety and depression before and after surgery, and psychological status of patients with a certain impact on quality of life, it should be targeted for individual characteristics of patients with targeted care measures to improve the psychological status of patients,thereby improving the quality of life of patients.

Objective:To systematically compare the prognosis in non-compressible torso hemorrhage（NCTH）treated by resuscitative endovascular balloon occlusion of the aorta（REBOA）and resuscitation thoracotomy（RT）.Methods:Data were searched form MEDLINE, EMBASE, PubMed, WanFang, CNKI and VIP databases to collect studies on the prognosis of patients with NCTH undergone REBOA and RT from inception to December 2020. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. The Meta-analysis was performed using Revman 5.3. The patients were divided into REBOA group and RT group according to the different surgical treatment methods on admission, and the prognosis of each group was evaluated. The difference of mortality rate, reoperation rate of laparotomy after operation, reoperation rate of embolization after operation and mortality rate in different operating room area were compared between the two groups. Publication bias was assessed using the Egger test.Results:A total of 2 prospective studies and 4 retrospective studies involving 2, 588 subjects were included. There were 1, 591 patients in REBOA group and 997 patients in RT group. Significant differences were observed in the mortality rate（ I2=68%, OR=0.33, 95% CI 0.26-0.42, P<0.01）, reoperation rate of laparotomy after operation（ I2=76%, OR=1.41, 95% CI 1.11-1.77, P<0.01）and reoperation rate of embolization after operation（ I2=84%, OR=0.76, 95% CI 0.59-0.99, P<0.05）between REBOA group and RT group. Subgroup analysis showed that the mortality rate in the ICU were not statistically different between the two groups（ I2=83%, OR=0.69, 95% CI 0.45-1.05, P>0.05）, but the mortality rate in the emergency room was lower in REBOA group than that in RT group（ I2=94%, OR=0.52, 95% CI 0.38-0.70, P<0.01）. Egger test showed that publication bias had little effect on the results. Conclusions:For patients with NCTH, REBOA can reduce the mortality rate and reoperation rate of embolization after operation, but increase the reoperation rate of laparotomy after operation when compared with RT. In addition, the emergency room may be a more suitable operationg room area for REBOA.
