Acupuncture is an ancient treatment method used in traditional Chinese medicine and has been popularized worldwide. Over the past decade, there has been an increase in the amount of acupuncture research, mostly comprised of randomized controlled trials (RCTs) that aimed to answer the question on the efficacy of acupuncture. However, poor methodology and low replicability in these acupuncture RCTs have resulted in uncertainty about the efficacy of acupuncture. In this review, current advancements and challenges in acupuncture RCTs, regarding the methodological aspects of randomization, blinding, sham acupuncture and quality of reporting, were discussed. While there have been advancements in various aspects, current acupuncture RCTs still face pressing issues such as inadequate randomization and blinding, unviable sham acupuncture controls, and poor reporting quality. Given these limitations, this review seeks to identify the methodological problems that are responsible for these problems and to suggest solutions that could help to overcome them so as to improve the quality of future studies evaluating the efficacy of acupuncture.

Objective To understand the distribution and antimicrobial resistance changes of bacteria isolated from pleural and peritoneal effusion in Hunan Province,and provide reference for correct clinical diagnosis and rational antimicrobial use.Methods Data reported by member units of Hunan Provincial Antimicrobial Resistance Survei-llance System from 2012 to 2021 were collected.Bacteria antimicrobial resistance surveillance method was imple-mented according to technical scheme of China Antimicrobial Resistance Surveillance System(CARSS),and WHO-NET 5.6 software was used to analyze the data of bacteria isolated from pleural and peritoneal effusion as well as antimicrobial susceptibility testing results.Results From 2012 to 2021,a total of 28 934 bacterial strains were iso-lated from specimens of pleural and peritoneal effusions from member units of Hunan Provincial Antimicrobial Re-sistance Surveillance System,with 5 752 strains from pleural effusion and 23 182 from peritoneal effusion.The top five bacteria isolated from pleural effusion were Escherichia coli(n=907,15.8％),Staphylococcus aureus(n=535,9.3％),Klebsiella pneumoniae(n=369,6.4％),Staphylococcus epidermidis(n=452,7.9％),and Staphy-lococcus haemolyticus(n=285,5.0％).The detection rate of methicillin-resistant Staphylococcus aureus(MR-SA)from pleural effusion was 24.3％-39.2％,and that of methicillin-resistant coagulase negative Staphylococcus(MRCNS)was 58.8％-77.1％.The top five bacteria isolated from peritoneal effusion were Escherichia coli(n=8 264,35.6％),Klebsiella pneumoniae(n=2 074,9.0％),Enterococcus faecium(n=1 458,6.3％),Staphylo-coccus epidermidis(n=1 383,6.0％),and Pseudomonas aeruginosa(n=1 152,5.0％).The detection rate of MRSA from peritoneal effusion was 22.1％-52.4％,which presented a decreasing trend(P=0.004).The detec-tion rate of MRCNS was 60.4％-79.4％.The resistance rates of Enterobacterales from peritoneal effusion to ce-fazolin,cefuroxime,ceftriaxone and cefepime all showed decreasing trends(all P＜0.05).Vancomycin-,linezo-lid-,and teicoplanin-resistant Staphylococcus strains were not found in pleural and peritoneal effusions.The resis-tance rates of Enterococcus faecium to most tested antimicrobial agents were higher than those of Enterococcus fae-calis.The resistance rates of Enterobacterales to imipenem and meropenem were ≤8.5％.The resistance rates of non-fermentative Gram-negative bacilli to imipenem and meropenem were ≤43.3％.Conclusion The data structure of Hunan Antimicrobial Resistance Surveillance System for pleural and peritoneal effusions from 2012 to 2021 is relatively complete.The constituent and antimicrobial susceptibility of isolated pathogenic bacteria vary in different years.

OBJECTIVE: To evaluate the feasibility and tolerability of metoprolol standard dosing pathway (MSDP) in Chinese patients with acute coronary syndrome (ACS). METHODS: In this multicenter, prospective, open label, single-arm and interventional study that was conducted from February 2018 to April 2019 in fifteen Chinese hospitals. A total of 998 hospitalized patients aged ≥ 18 years and diagnosed with ACS were included. The MSDP was applied to all eligible ACS patients based on the standard treatment recommended by international guidelines. The primary endpoint was the percentage of patients achieving the target dose at discharge (V2). The secondary endpoints included the heart rate and blood pressure at V2 and four weeks after discharge (V4), and percentage of patients experiencing bradycardia (heart rate < 50 beats/min), hypotension (blood pressure < 90/60 mmHg) and transient cardiac dysfunction at V2 and V4. RESULTS: Of the 998 patients, 29.46% of patients achieved the target dose (≥ 95 mg/d) at V2. The total population was divided into two groups: target group (patients achieving the target dose at V2) and non-target group (patients not achieving the target dose at V2). There was significant difference in the reduction of heart rate from baseline to discharge in the two groups (-4.97 ± 11.90 beats/min vs. -2.70 ± 9.47 beats/min, P = 0.034). There was no significant difference in the proportion of bradycardia that occurred in the two groups at V2 (0 vs. 0, P = 1.000) and V4 (0.81% vs. 0.33%, P = 0.715). There was no significant difference in the proportion of hypotension between the two groups at V2 (0.004% vs. 0.004%, P = 1.000) and V4 (0 vs. 0.005%, P = 0.560). No transient cardiac dysfunction occurred in two groups during the study. A total of five adverse events (1.70%) and one serious adverse event (0.34%) were related to the pathway in target group. CONCLUSIONS In Chinese ACS patients, the feasibility and tolerability of the MSDP have been proved to be acceptable.

OBJECTIVE: To retrospectively analyze the laborotary test results and clinical data of 31 patients with mixed phenotype acute leukemia (MPAL) in order to summarize and discuss the biological characteristics, curative effect, and prognosis of each subtype of MPAL based on immunophenotype results. METHODS: MPAL patients diagnosed and treated in our hospital from July 2013 to January 2019 were selected to analyze the data of cell morphology, immunophenotyping, cytogenetics, molecular biology (MICM), and routine blood at initial diagnosis. Follow-up was carried out until the last discharge time. RESULTS: Among 31 patients, there were 19 males and 12 females, with a median age of 41(12-76) years old. According to the results of immunophenotyping and EGIL score, there were 16 cases of myeloid-T lymphoid mixed phenotype (myeloid-T group), 9 cases of myeloid-B lymphoid mixed phenotype (myeloid-B group), 5 cases of T-B lymphoid mixed phenotype (T-B group), and 1 case of myeloid-T-B lymphoid mixed phenotype. Compared between different subtypes, the antigen expression characteristics were the highest positive rate and expression rate of HLA-DR in myeloid-B group, and the positive rate of CD2 in T-B group was significantly higher than that in the myeloid-T group. Meanwhile, the expression rates of CD7 and cCD3 (cytoplasmic CD3) in T-B group were higher than those in myeloid-T group, and cCD79a was positive in all cases of myeloid-B group and T-B group. The median WBC of T-B group was 81.92×10⁹/L, which was significantly higher than that of the other two groups (P<0.05). The quantitative results of WT1 were higher than 10^-4 in 92.6% of the patients, and the WT1 expression level in myeloid-B group was significantly lower than the other two groups (P<0.01). Among the 9 patients with myeloid-B mixed phenotype, 5 cases showed BCR-ABL positive. Among 28 patients followed up, 21 cases achieved complete remission (CR), the median time to first obtain CR was 32.5(9-75) days, and the median follow-up time was 16 months (range from 21 days to 6 years). The CR rate and median overall survival (OS) time in myeloid-B group were 88.9% and 40 months, which were higher than the other two groups. The CR rate and 3-year OS rate in T-B group were relatively lower (50.0%, 0). CONCLUSION WT1 gene is highly expressed in patients with MPAL, and each subgroup of MPAL based on immuophenotype has its unique antigen expression characteristics. Compared with myeloid-T group and T-B group, myeloid-B group can acquire higher remission rate and have better prognosis.

OBJECTIVE： To study the protective effect and mechanism of Miao medicine Liangjiang weiyang capsule on gastric ulcer model rats. METHODS： Rats were randomly divided into normal group （normal saline）， model group （normal saline）， positive control group （omeprazole， 0.02 g/kg） and Liangjiang weiyang capsule low-dose， medium-dose and high-dose groups （0.3， 0.6， 1.2 g/kg）， with 12 rats in each group. All rats were intragastrically administered once a day for consecutive one week. 1 h after last administration， all rats except those in normal group were given the absolute ethanol to induce gastric ulcer model. 1 h after modeling， gastric juice volume， gastric juice pH， pepsin activity， gastric ulcer area and inhibitory rate of gastric ulcer were recorded in each group. Histopathological changes of gastric mucosa in rats of each group were observed by HE staining. The serum levels of TNF-α and IL-6 were determined by ELISA. The expression of nuclear factor-κB pathway related protein （p-NF-κB p65， p-IκBα） in gastric tissue of rats were determined by Western blot. RESULTS： Compared with normal group， gastric juice volume， pepsin activity， gastric ulcer area， TNF-α and IL-6 levels in serum， p-NF-κB p65 and p-IκBα levels in the gastric tissue were significantly increased/rised （P＜0.05）， while gastric juice pH was significantly decreased （P＜0.01）； there were gastric mucosal hyperemia and redness， obvious defect of mucosal epithelial cells， destruction of gland structure and incomplete cell structure. Compared with model group， gastric juice volume， pepsin activity， gastric ulcer area and the levels of TNF-α and IL-6 were reduced/decreased significantly in positive control group， Liangjiang weiyang capsule medium-dose and high-dose groups （P＜0.05 or P＜0.01）， while pH value of gastric juice was increased significantly （P＜0.05）； gastric mucosa was normal， gland destruction was alleviated and cell structure was intact. The levels of p-NF-κB p65 and p-IκBα in gastric tissue were significantly decreased in Liangjiang weiyang capsule high-dose groups （P＜0.05）. CONCLUSIONS： Liangjiang weiyang capsule play a role to protect gastric ulcer by increasing gastric juice pH， inhibiting pepsin activity， reducing the release of inflammatory factors as TNF-α， IL-6 and inhibiting the expression of NF-κB pathway related protein.

Objective To evaluate the clinical safety and efficacy of percutaneous interventional therapy in pediatric patients with secundum atrial septal defect(ASD).Methods Clinical data of 40 patients(age≤2 years)with secundum atrial septal defect treated in our hospital from February 2014 to December 2017 were analyzed retrospectively. There were 13 males and 27 females in these patients.Ultrasound of heart showed that there were 37 patients with single ASD,3 patients with multiple ASDs.One associated with pulmonary stenosis(PS),and 1 associated with patent ductus arteriosus.There were 6 patients with pulmonary hypertension, and the diameter of ASD was (10.6 ± 2.0) mm. All patients were proved to have secundum atrial septal defect before intervention.In the intervention,the transport system was delivered along the femoral vein,inferior vena cava and right atrium through atrial septal defect to the left atrium,and the occluder was released there. Results Of the 40 patients, 38 cases were successfully implanted, and the other two patients were not satisfied with the location of occlusion.The diameter of the ASD occluder was(12.0±2.1)mm and the transport sheath 7-9 F.Plug2 occluder was implanted in the patient with patent ductus arteriosus.To the patient with PS,pulmonary valve balloon angioplasty was performed,and then the pressure gradient reduced obviously, after that ASD occlusion was performed. The total follow up period was from 2 months to 3 years.No residual shunt and unsatisfactory device position were found during the follow up period.The pulmonary pressure reduced to normal,and the right atrium and right ventricle were smaller in a different degree. All patients had no arrhythmia and other complications.Conclusion Transcatheter closure of ASD is safe,reliable,and has fewer complications.It is worthy of popularization and application.Appropriate occluder should be selected according to the size and edge of ASD to reduce complications,such as residual shunt and valve injury.

Objective To investigate the curative effects of various infusion volumes on liver-related metabolic mechanism in the treatment of hemorrhagic shock.Methods A severe hemorrhagic shock rabbit model was established in 30 rabbits.The rabbits were randomly divided into three groups:non-infusion group (A), conventional infusion group (B), and excessive infusion group (C) (n=10 in each group).Taking group B as the control, groups A and C were observed for the damage of non-infusion and excessive infusion, respectively.The outcomes in the three groups and their relations with liver tissue metabolism changes were analyzed with gas chromatograph-mass spectrometer (GC-MS).Results The mortality in groups A, B, and C group were 80％, 0％, and 70％, respectively.The liver tissue metabolic profile in group B showed statistically significant difference compared with that in groups A and B.In group C, the levels of 21 metabolites were lower than those in group B, and the levels of8 metabolites were lower than those in group A.The relative contents of various metabolites were correlated with infusion volumes, and the succinic acid content was associated with death events (P＜0.05).Conclusion The conventional infusion has significant curative effect on hemorrhagic shock.The metabolites of liver tissues with excessive infusion are generally decompensated and have longer survival time than those in non-infusion group, which may caused by the excessive infusion-induced blood volume increase after hemorrhagic shock.Tissue fluid dilution is an important cause of death.

The study was aimed to establish a stable, accurate site specific PCR identification system to identify Manis pentadactyla and its adulterants using DNA molecular identification. The genomic DNA was extracted from experimental samples using the DNA extraction kit. The Cytb and CO Ⅰ genes were amplified using PCR and sequenced bi-directionally. Obtained sequences were assembled using the BioEdit software. The neighbor-joining tree was constructed by MEGA 6.0. Specific identification primers were designed according to the specific allelets, and PCR reaction system was optimized. The results indicated that the Cytb and CO Ⅰ sequence both were able to be used to identify M. pentadactyla and its adulterants. With the specific primers CO Ⅰ-S10/A5, the M. pentadactyla could be amplified a 400 bp DNA band when the annealing temperature ranged from 55 to 60 ℃ and the amount of DNA template ranged from 3 to 100 ng within 35 PCR cycles. However, other adulterants displayed no relevant bands. So that primers CO Ⅰ- S10 / A5 can be used to identify the M. pentadactyla with the adulterants.
