The deep analysis has been done on the cases of adverse events and common injury of cupping therapy encountered in recent years in terms of manipulation and patient's constitution. The adverse events of cupping therapy are commonly caused by improper manipulation of medical practitioners, ignoring contraindication and patient's constitution. Clinical practitioners should use cupping therapy cautiously, follow strictly the rules of standard manipulation and medical core system, pay attention to the contraindication and take strict precautions against the occurrence of adverse events.

Abstract：In recent years，the outbreak and prevalence of respiratory infectious diseases in the world seriously endanger human health，among which the respiratory infectious diseases caused by viral infection account for a large proportion. The use of vaccines and common antiviral drugs is an effective way to fight viral infection，but there are also problems such as lag and drug resistance. Monoclonal antibodies against respiratory viral infections provide a new strategy for clinical treatment. This paper reviews the development of monoclonal antibody against respiratory virus and its application in respiratory viral infectious diseases. Keywords：Respiratory viral infectious diseases；Respiratory syncytial virus（RSV）；Influenza virus（IFV）；Coronavirus （CoV）；Monoclonal antibody

Objective To investigate the rationality and safety of dengzhanxixin injection used in elderly inpatients. Methods The clinical data of 986 inpatients including 620 males and 366 females were collected, and questionnaires containing age, sex, discharge diagnosis, symptoms, drug dosage, course of treatment, laboratory examination, adverse drug reaction and drug effect were analyzed. Results For the 986 cases, the average age was(74.3±7.5)years. The average dose of dengzhanxixin injection was (38.2±4.4) ml, once daily by intravenous drip, and the average period of treatment was (10.8±5.2) days. The adverse reaction rate was 0.81%. The levels of blood glucose and hemoglobin were decreased after treatment(t orμ=1226.5,2620.0, both P<0.05), but there were no statistical differences in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), blood urea nitrogen (BUN) and white blood cell count (WBC) before and after treatment (t or μ=122.5, 405.0, 513.5, 996.5, 956.5, all P>0.05). Conclusions It is safe to use dengzhanxixin injection according to the medication description for elderly inpatients.

BACKGROUND: Sinomenine is an alkaloid monomer extracted from a Chinese medicinal herb sinomenium acutum stem. It is used in the therapy of the rheumatoid arthritis and has clear and definite therapeutic effects, but the therapeutic mechanism is unclear.OBJECTIVE: To observe the effect of sinomenine at different doses in vitro on the activity of nuclear factor-κB(NF-κβ) and mRNA expressions of the tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) andinterleukin-10 (IL-10) in the synovial cells of the rats with adjuvant arthritis(AA) to explore the probable mechanism of sinomenine in the treatment of rheumatoid arthritis(RA).DESIGN: A controlled repeated measuring study based on the cells.SETTING: Department of traditional chinese medicine and the institute of burn research of a military medical university.MATERIALS: This study was finished at the Laboratory of the Institute of Burn Research of Chinese PLA. The experimental animals were 25 healthy male Wistar rats of clean grade. The AA model rats were made and the synovial cells were collected and grouped as follows: normal control group, AA group,AA + sinomenine 30 mg/L group, AA + sinomenine 60 mg/L group, AA + sinomenine 120 mg/L group. The activity of the NF-κB was measured by the electrophoresis mobility shift assay(EMSA) . The mRNA expressions of the TNF-α, IL-1β and IL-10 were measured by reverse transcription-PCR assay.MAIN OUTCOME MEASURES: The results of the changes of the activity of the NF-κB and the mRNA expressions of the TNF-α, IL-1β and IL-10 in the synovial cells of the rats with adjuvant arthritis after the treatment with sinomenine at different doses.RESULTS: Compared with the normal control group, the activity of the NF-κB and the mRNA expressions of the TNF-α, IL-1β and IL-10 in the synovial cells in the AA group all increased significantly and the outcomes were 17±6, 0.570±0.047, 0.730±0.093, 0. 683 ±0.081 (t= 2.71 -4.07, P < 0.05). After the administration of sinomenine, the activity of NF-κB showed a good correlation with mRNA expressions of the TNF-αandIL-13(r=0.810, P <0.001; r=0.562, P <0.05), but no statistical relevance with mRNA expression of IL-10 was established. Sinomenine showed a dose-dependent inhibition on the activity of the NF-κB and the mRNA expressions of the TNF-α and IL-1β in a certain range of concentrations(30-120 mg/L), but no dose-dependent inhibition on mRNA expression of the IL-10 was observed.CONCLUSION: Through the inhibition of the activity of the NF-κB,sinomenine decreased the mRNA expressions of the TNF-α and the IL-1β in the synovial membrane cells.

ObjectiveTo evaluate the diagnostic value of ultrasound or CT guided percutaneous Trucut needle biopsy on the diagnosis of pancreatic tumors.Methods One hundred and twenty-four patients clinically diagnosed as pancreatic cancer without pathological diagnosis underwent percutaneous pancreatic biopsy by using Trucut needle under ultrasound or CT guidance.ResultsOne hundred and nine procedures of ultrasound-guided biopsy and 15 procedures of CT-guided biopsy were performed,and one patient received 2.3times of punctures.Tissue samples were obtained in all 124 patients,the diagnostic accuracy was 95.2％,among them 115 were adenocarcinoma,5 were cystadenoma,2 were metastasis cancer,1 was cancer of unknown origin and 1 was normal.The sensitivity,specificity,and accuracy were 99.2％ 100％,and 99.2％,respectively.Transient serum amylase increase was observed in 3 patients; 5 patients' abdominal pain aggravated,but all recovered with conservative management.One patient was found to have tumor seeding on the spot of insertion after 34 days.No other major complications occurred.ConclusionsUltrasound or CTguided percutaneous pancreatic 16 ～ 18G Trucut needle biopsy is a safe and simple procedure with excellent diagnostic value for pancreatic cancer.

Ulcerative colitis (UC) is a chronic non-specific disease of the rectum and colon. The disease cause is still unclear. Due to the repeated episodes of UC, the treatment is very difficult. There are serious impact on pa-tients' life and work. According to the current UC condition and existed problems with Chinese medicine treat-ment and in combination with experiences of new Chinese medicine drug development of the author, a new Chi-nese medicine drug research idea of UC has been proposed. It includes the establishment of UC animal model in line with the characteristics of Chinese medicine and the selection of appropriate clinical treatment targets.

Objective To investigate the availability of N-terminal pro-brain natriuretic peptide (NT proBNP) in the detection of early ventricular diastolic dysfunction by polymyositis/dermatomyositis (PM/DM).Methods A total of 46 PM/DM patients without symptoms of heart involvement were prospectively studied by standard echocardiography and the longitudinal mitral annular velocities was measured by tissue Doppler echocardiography (TDI).Plasma NT-proBNP was measured in all patients.Multivariate Logistics regression analysis was applied to investigate the risk factors for early cardiac complications.The availability of NTproBNP was evaluated by receiver operating characteristic (ROC) analysis.Results There were 22 patients complicated with early diastolic dysfunction (E/Em ≥ 8) by TDI.The multi-factors Logistic regression analysis showed that the age of onset (OR=1.117,95％CI 1.005-1.243,P=0.040) and plasma NT-proBNP (OR=1.022,95％CI 1.001-1.042,P=0.036) were risk factors for early left ventricular diastolic dysfunction.The level of NT-proBNP was positively correlated with E/Em value(r=0.687,P=0.000).ROC showed NT-proBNP could reliably detectearly ventricular diastolic dysfunction [area under the curve 0.858 (95％ CI 0.735-0.981,P＜0.01)].If PM/DM patients with normal TDI(E/Em＜8) were used as controls,and 120 pg/ml was used as the cut-off concentration,the sensitivity and specificity of NT-proBNP for the early ventricular diastolic dysfunction was 81.8％ and 91.7％ respectively.Conclusion Age at onset and plasma NT-proBNP are risk factors for early left ventricular diastolic dysfunction.The level of NT-proBNP is positively correlated with E/Em value.The plasma NT-proBNP concentration higher than 120 pg/ml maybe a marker for early left ventricular diastolic dysfunction.
