Abstract: Objective　To analyze the recent cluster outbreaks of imported malaria and explore the risks, challenges and countermeasures for dealing with such events during malaria post-elimination era of malaria, and to provide reference for effectively addressing the risks and consolidating the achievements of malaria elimination. Methods　The individual malaria case data from "The Information System for Infectious Disease Surveillance" and "The Information System For Parasitic Diseases Prevention And Control" were collected，and the diagnosis classification, infection source, time and space distribution of cases were analyzed. Results　From January 1 to August 11, 2022, a total of 429 malaria cases were reported nationwide, an 18.9% decrease compared to the same period last year (529 cases), all of which were imported cases. The overall weekly trend of the outbreak remained stable, but since Week 31 (July 25-31), there has been a significant increase in the number of cases, with a peak on August 5. From July 25 to August 11, 2022, a total of 162 malaria cases were reported nationwide, up 315.4% from 39 cases in the same period last year, accounting for 37.8% of the total cases up to August 11, 2022. The main source of imported infections was Guinea (95 cases, 58.6%), with most cases reported in Longgang District, Shenzhen City, Guangdong Province (30 cases), Shilin County, Kunming City, Yunnan Province (21 cases), Chaoyang District, Beijing (11 cases), and Xiaoshan District, Hangzhou City, Zhejiang Province (7 cases). Conclusions　Due to the concentration of returnees to China, several entry port cities simultaneously experienced cluster outbreaks of imported malaria, which brought immense pressure and challenges to local medical and health institutions. Health facilities at all levels need to maintain high vigilance and sensitivity, be well prepared, and avoid death and secondary transmission caused by imported cases.

OBJECTIVE:To provide for rational use of Tripterygium glycosides tablet clinically. METHODS:The utilization of Tripterygium glycosides tablet were collected from hospital information system(HIS)in our hospital during Jun. 2012-Jun. 2014. Then the data about the basic information,patients’age,departments and diagnosis,were analyzed by the Excel. RESULTS:The application of Tripterygium glycosides tablet remained stable since Jun. 2012. There were 4 600 prescriptions in average every year, and the age of patients was distributed from 11 to 90. Tripterygium glycosides tablet was mainly used in rheumatology department (52.11%),followed by TCM rheumatology department(20.62%),skin disease and venereal disease department(18.15%),ne-phrology department(3.52%)and integrated traditional and western medicine cardiology department(1.77%). It was mainly used to treat rheumatoid arthritis,Sjogren's syndrome,polymyalgia rheumatica,osteoporosis and nephrotic syndrome. CONCLUSIONS:The application of Tripterygium glycosides tablet as immunosuppressant is widely used,but the age of patient is with wide distribu-tion;the narrow gap exists between minimum effective dose and minimum lethal dose;so ADR should be concerned closely.

Background:For patients with liver cirrhosis and acute decompensation(AD),it is of great clinical importance to predict short-term mortality at admission. It has been reported that CLIF-C OF,MELD and MELD-Na score can accurately predict the short-term mortality,but all these scoring systems are complicated and have limits in their application. Aims:To define a simple and objective scoring system -- simplified MELD score for short-term mortality prediction in HBV-related cirrhotic patients with AD. Methods:A total of 890 consecutive HBV-related cirrhotic patients with AD hospitalized during Jan. 2005 to Dec. 2010 at Shanghai Ren Ji Hospital were enrolled retrospectively. Clinical data and patients’outcome were collected,and simplified MELD score was calculated by using total bilirubin,international normalized ratio and creatinine values at admission. Patients were classified into different prognostic groups according to their 28-day mortalities and simplified MELD score. Kaplan-Meier survival curve was used to analyze the 1-year accumulate survival rate,and ROC curve was used to evaluate the performance of different scoring systems in predicting 28-day mortality. Results:Simplified MELD score at admission could classify HBV-related cirrhotic patients with AD into low,moderate and high 28-day mortality groups and different long-term prognostic groups;the score of low,moderate and high 28-day mortality group was 0-2,3 and 4-6,respectively,and the corresponding mortality was 5. 5% ,19. 8% and 48. 6% ,respectively. Simplified MELD score had the same good performance as compared with the CLIF-C OF,MELD and MELD-Na scores in predicting 28-day mortality,the area under ROC curve was 0. 828,0. 831,0. 828 and 0. 830,respectively. Conclusions:Simplified MELD score can accurately classify HBV-related cirrhotic patients with AD into low,moderate and high 28-day mortality groups at admission. It is convenient for using in clinical practice.

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.

Objective: To establish a multiplex PCR-microarray method for detecting important enteropahogens.Methods: Uniplex and multiplex PCR were performed to obtain the best primer sets for identifying the target bacteria at species and multi-species level.Fluorescent dyes were mixed into PCR reaction to determine whether it can affect the efficiency of amplification.To improve the efficiency of microarray,a 35 pairs primer-labeling system was optimized based on the hybridization results to find the best combination to avoid false negative results.Results: Specific PCR products were all obtained using species-specific primer sets.More preferential amplification may happen when more primer pairs were added to the reaction.The hybridization results showed a positive association between the efficiency of multiplex-PCR and signal intensity.Conventional PCR yielded more products than fluorescent dyes labeled PCR.Thirty-five primers were divided into three different combinations to label target respectively,hybridization results showed a high specificity.Conclusion: Mixing fluorescent dyes into PCR may reduce the efficiency of amplification and hybridization,but may have no effect on the analysis of hybridization results.The hybridization efficiency of microarray depends on the amplification efficiency of multiplex PCR.For microarray target labeling,three primer sets could be used to avoid negative hybridization led by preferential amplification of multiplex-PCR.It indicates that the multiplex PCR-microarray method is an attractive diagnosis tool for the high-throughput identification of enteropathogenic organisms especially for multiple causative agents and epidemiological investigations.

The purpose of this study was to evaluate the roles of different housing environments in neurological function,cerebral metabolism,cerebral infarction and neuron apoptosis after focal cerebral ischemia.Twenty-eight Sprague-Dawley rats were divided into control group (CG) and cerebral ischemia group,and the latter was further divided into subgroups of different housing conditions:standard environment (SE) subgroup,individual living environment (IE) subgroup,and enriched environment (EE) subgroup.Focal cerebral ischemia was induced by the middle cerebral artery occlusion (MCAO).Beam walking test was used to quantify the changes of overall motor function.Cerebral infarction and cerebral metabolism were studied by in vivo magnetic resonance imaging and 1H-magnetic resonance spectra,respectively.Neuron necrosis and apoptosis were detected by hematoxylin-eosin and TUNEL staining methods,respectively.The results showed that performance on the beam-walk test was improved in EE subgroup when compared to SE subgroup and IE subgroup.Cerebral infarct volume in IE subgroup was significantly larger than that in SE subgroup (P＜0.05) and EE subgroup (P＜0.05) on day 14 after MCAO.NAA/Cr and Cho/Cr ratios were lower in MCAO groups under different housing conditions as compared to those in CG (P＜0.05).NAA/Cr ratio was lower in IE subgroup (P＜0.05) and higher in EE subgroup (P＜0.05) than that in SE subgroup.NAA/Cr ratio in EE was significantly higher than that in IE subgroup (P＜0.05).Cho/Cr ratio was decreased in MCAO groups as compared to that in CG (P＜0.05).A significant decrease in normal neurons in cerebral cortex was observed in MCAO groups as compared to CG (P＜0.05).The amount of normal neurons was less in IE subgroup (P＜0.05),and more in EE subgroup (P＜0.05) than that in SE subgroup after MCAO.The amount of normal neurons in EE subgroup was significantly more than that in IE subgroup after MCAO (P＜0.05).The ratio of TUNEL-positive neurons in EE was significantly lower than that in SE subgroup (P＜0.05) and IE subgroup (P＜0.05).Correlation analysis showed that the beam walking test was negatively correlated with NAA/Cr ratio (P＜0.05).Cerebral infarct volume was negatively correlated with both NAA/Cr ratio (P＜0.01) and Cho/Cr ratio (P＜0.01).The amount of normal cortical neurons was positively correlated with both NAA/Cr ratio (P＜0.01) and Cho/Cr ratio (P＜0.05).The TUNEL-positive neurons showed a negative correlation with both NAA/Cr ratio (P＜0.01) and Cho/Cr ratio (P＜0.01).This study goes further to show that EE may improve neurological functional deficit and cerebral metabolism,decrease cerebral infarct volume,neuron necrosis and apoptosis,while IE may aggravate brain damage after MCAO.

BACKGROUND: The complications of systemic inflammatory response syndrome (SIRS) include acute lung injury, acute kidney injury, shock, and multiple organ dysfunction syndrome (MODS). In recent years, how to clear inflammatory mediators has become a hot topic in critical care medicine. Researchers hypothesize that continuous blood purification (CBP) can effectively eliminate a variety of inflammatory mediators which participate in the occurrence of MODS and adjust the immune imbalance. This study aimed to observe the effects of CBP in MODS patients. METHODS: In this retrospective clinical study, a total of 38 MODS patients, 18 males and 20 females, were enrolled. After conventional therapy, all the patients received CBP. Biochemistry, blood gas analysis, oxygenation index, mean arterial blood pressure (MAP), acute physiology and chronic health evaluation (APACHE) II scores were monitored. RESULTS: After CBP, the vital signs of patients were rapidly stable, and electrolyte disorders and acid-base imbalance were corrected. Renal function, blood gas, oxygenation index were all improved. MAP was increased, and APACHE II score was significantly decreased. All patients had good tolerance, stable hemodynamics, and no obvious adverse reaction on CBP compared with pre-CBP. CONCLUSION: CBP can effectively clean toxins, correct electrolyte acid-base balance, and improve systemic inflammatory response syndrome and the organ function of MODS patients.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.
