Objective To compare the analgesic effects of fire needling, conventional acupuncture and acupoint catgut embedding in rats with rheumatoid arthritis.Methods Fifty healthy male SD rats were randomized into control, model, acupuncture, fire needling and catgut embedding groups, 10 rats each. A SD rat model of rheumatoid arthritis was made by intracutaneous injection of complete Freund’s adjuvant into the right hind foot pad. Right Kunlun and Zusanli were selected as therapeutic points in the three groups and given fire needling, acupuncture or catgut embedding. The right paw mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were used as observation indices and measured in every group of rats at one day before and four days after model making and at one, seven and fourteen days after the beginning of treatment. Rat paw inflammatory tissues were separated after the completion of treatment. The IL-1 and TNF-α contents of them were measured. Results There were statistically significant differences in MWT and TWL between the model, acupuncture, fire needling or catgut embedding group and the control group after model making, and one, seven and fourteen days of treatment (P<0.01). There were statistically significant differences in MWT and TWL between the fire needling group and the model, acupuncture or catgut embedding group after one, seven and fourteen days of treatment (P<0.01,P<0.05). There was a statistically significant difference in MWT between the acupuncture or catgut embedding group and the model group after one, seven and fourteen days of treatment (P<0.01). There was a statistically significant difference in TWL between the acupuncture or catgut embedding group and the model group after seven and fourteen days of treatment (P<0.01,P<0.05). There were statistically significant differences in IL-1 and TNF-α contents between the model, acupuncture, catgut embedding or fire needling group and the control group after model making (P<0.01). after treatment, there were statistically significant differences in IL-1 and TNF-α contents between the acupuncture, catgut embedding or fire needling group and the model group and between the acupuncture or catgut embedding group and the fire needling group (P<0.05).Conclusions Fire needling can raise pain threshold in rats with rheumatoid arthritis. It alleviates rheumatoid arthritis-induced chronic pain by reducing the inflammatory factor content of affected muscular tissues.

Objective By analysis of the key performance indexes of the clinical laboratory automation system, to clarify the advantage and optimize the comprehensive performance of the laboratory automation system.Methods Key performance indexes were Collected from January 2017 to April 2017 in biochemistry and immunoassay group of Clinical Laboratory of Shanghai Tong Ren Hospital.(1)The data were collected and compared by the before-and-after method,the starting time of the automation system and initial sample test were analyzed.(2)Key performance indexes were analyzed for the time of specimen registration,inspection,and reporting.(3)The specimen turnaround time(TAT)was analyzed based on two months operation of the laboratory automation system.In view of disadvantage of infectious assays, setting up priority sample absorption, then TAT performance was re-evaluated.(4)By the assessment of total serum dosage required in the automation system, the number of blood vacuum tubes were reduced reasonably.The pros and cons of laboratory automation system were analyzed and the potential improvement were proposed.Results (1)According to the sample peak shift forward,the system start time could move forward 30 minutes earlier.(2)With the adopting of railway logistics,the specimens were sent to the lab and the registration time was at 7:25 am,and the time required for specimen delivery was greatly reduced which made specimen test,report and audit time all moved forward accordingly.(3)Data has shown that specimen TAT declined dramatically based on the performance of the first two month operation of the automation system,biochemical items were shortened 2 h,and the immunoassay shortened 4 h,respectively.Moreover the trend keeps better gradually.With setting up priority absorption infectious tests,the TAT was improved greatly,TAT reduced the average by 40 min.(4)500 μl(including the sample in dead space of vacuum tube)were needed for all the 65 biochemical items included in the system, and 1 495 μl serum were used for the 28 immunoassay.As a result, a total of 2 000 μl serum will be enough for sample analysis by the system, which provided the feasibility to reduce 3 vacuum tubes averagely.Considering the current automation system does not include all the analysis items in our lab directory, a few tests remain to be performed on offline instruments respectively.The methodology for some infectious agents are different from previous method, therefore some test results may need a period of time for comprehensive clinical appreciation.Furthermore,due to the parallel connection of multiple instruments included in the system, more rigorous and frequent quality control becomes a necessity,which may rely on more strict quality control procedure to guarantee the quality.Conclusions The application of the automation system significantly enhanced the efficiency of clinical laboratory all round.In addition, by the quantitative indicators, it is possible to monitor the system operation performance real time, which may feedback and facilitate the improvement constantly,and result in auto confirmation the majority results,eventually.

Tripterygium glycosides tablet(TGT),the classical commercial drug of Tripterygium wilfordii Hook.F.has been effectively used in the treatment of rheumatoid arthritis,nephrotic syndrome,leprosy,Behcet's syndrome,leprosy reaction and autoimmune hepatitis.However,due to its narrow and limited treatment window,TGT-induced organ toxicity(among which liver injury accounts for about 40％of clinical reports)has gained increasing attention.The present study aimed to clarify the cellular and molecular events underlying TGT-induced acute liver injury using single-cell RNA sequencing(scRNA-seq)technology.The TGT-induced acute liver injury mouse model was constructed through short-term TGT exposure and further verified by hematoxylin-eosin staining and liver function-related serum indicators,including alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin.Using the mouse model,we identified 15 specific subtypes of cells in the liver tissue,including endothelial cells,hepatocytes,cholangiocytes,and hepatic stellate cells.Further analysis indicated that TGT caused a significant inflammatory response in liver endothelial cells at different spatial locations;led to marked inflammatory response,apoptosis and fatty acid metabolism dysfunction in hepatocytes;activated he-patic stellate cells;brought about the activation,inflammation,and phagocytosis of liver capsular macrophages cells;resulted in immune dysfunction of liver lymphocytes;disturbed the intercellular crosstalk in liver microenvironment by regulating various signaling pathways.Thus,these findings elaborate the mechanism underlying TGT-induced acute liver injury,provide new insights into the safe and rational applications in the clinic,and complement the identification of new biomarkers and ther-apeutic targets for liver protection.

BACKGROUNDTo evaluate and compare the effects and toxicity of the domestic product of recombinant mutant human tumor necrosis factor (rmhTNF) combined with chemotherapy and chemotherapy alone in the treatment of patients with non-small cell lung cancer (NSCLC).

METHODSTwo hundred patients with NSCLC in multicenter were randomly devided into trial group (150 cases) and control group (50 cases). Chemotherapy with CAP regimen was given to the patients. Meanwhile, rmhTNF injection of 4×10⁶U/m² was also given from the 1st to 7th days, the 11th to 17th days on the chemotherapy cycle in the trial group. The control patients received chemotherapy alone. Twenty-one days were as a cycle, 2 cycles were given to each patient. The chemotherapeutic effects and toxicity were observed and compared between the two groups after the therapy.

RESULTSof the 200 patients, 5 cases in the trial group and 3 cases in the control group were out of the trial because of economy. The other 192 cases (145 cases in the trial group and 47 cases in the control group) could be analyzed and evaluated the clinical effects and toxicity. The response rate of chemotherapy was 46.90% (68/145) in the trial group and 17.02% (8/47) in the control group respectively ( P =0.001). The KPS scores was 86.02±9.74 in the trial group, and 80.14±9.10 in the control group ( P =0.025). No significant difference of degree III+IV toxicity was observed between the two groups ( P > 0.05). The side effects related to rmhTNF included slight fever, cold-like symptoms, pain and red and swelling in the injection site. All of them were mild and didn't need any treatment and disappeared after the therapy. There were no severe abnormality of liver and kidney function and ECG in both groups.

CONCLUSIONSThe results demonstrate that the effects of domestic rmhTNF combined with chemotherapy are remarkably higher than that of chemotherapy alone in the treatment of NSCLC. rmhTNF can increase the sensitivity to chemotherapy and improve the quality of life of the patients with slight toxicity. Hence rmhTNF is worth expanding clinical use.
