The report quality of randomized controlled trials (RCTs) of moxibustion for knee osteoarthritis (KOA) in China was evaluated by Consolidated Standards for Reporting of Trials (CONSORT) and Standards for Reporting Interventions in Controlled Trials of Moxibustion (STRICTOM). Computer and manual retrieval was used. Four databases of China National Knowledge Infrastructure (CNKD, China Biomedicine (CBM), VIP and WNFANG were searched in combination with manual retrieval for relevant journals to screen the literature that: met the inclusive criteria, and CONSORT and STRICTOM were used to assess the report quality. A total of 52 RCTs were included. It was found that unclear description of random methods, low use of blind methods, no allocation concealment, no sample size calculation, no intention-to-treat analysis,inadequate report of moxibustion details and no mention of practitioners background existed in the majority of the RCTs. Although the quality of RCTs of moxibustion for KOA was generally low, reducing the reliability and homogeneous comparability of the reports ,the quality of heat-sensitive moxibustion RCTs was high. It was believed that in order to improve the reliability and quality of RCTs of moxibustion, CONSORT and STRICTOM should be introduced into the RCT design of moxibustion and be strictly performed.

Objective To evaluate the feasibility of methylene blue as a method in lymphatic mapping and the effect factors of SLNB identification rate. Methods The results of SLNB in 276 patients with clinical stage T-T2N0M0 breast eaneer were analyzed to evaluate the effect factors of identification rate and false-neg-ative rate of SLNB. Results The identification of SLN was carried out using methylene blne . When the mapping time of SLN and lymphatic were controlled in 20～30 minutes, the SLN could be visualized easily. SLN was successfully identified in 246 of 276 patients (89.1%) ,423 SLNs were retrieved(1～4). The SLN accurately predicted the status of the axilla in 226 of 246 patients (77.3%) yielding a FNR(false negative rate)of 8.1% (20/246) ,false positive rate of0, and an accuracy of 91.9% (226/241). For the identified rate of SLN, the clinical stage of T2N0M0 disease was higher than the clinical stage of T1N0M0 disease (P=0.046,P<0.05), Upper outer quadrant and lower outer quadrant were higher than other evidently (P<0.0010). SLNs were easily retrieved in those cases aged above 50 years than below 50 years (P<0.001).In the view of false-negative rate of SLNB, the FNR rate in patients of 50 years old was less than older ones (P=0.037, P<0.05). No significant correlation was found between the stage of TMN, the expression of ER and PR, histologic status and FNR. Conclusion When SLNB was performed using methylene blue, we found age, clinical stage of TMN, the location of tumor had relationship with the identified rate of SLN. Ag-ing and location of tumor may adversely affect FNR of SLNB.

Objective To investigate the clinical significance of serum anti-Saccharomyces cerevisias antibody (ASCA),anti-outer membrane porin C (anti-OmpC),antibody to Pseudomonas fluorescens-associated sequence I2 (anti-I2 )and antibody to bacterial flagellin (anti-CBirl )in the diagnosis and treatment of inflammatory bowel disease (IBD).Methods From 2011 to 2013,87 patients with IBD were enrolled and divided into Crohn′s disease (CD)group (66 cases)and ulcerative colitis (UC)group (21 cases).A total of 62 age and gender matched healthy individuals were enrolled as the control group. Fasting blood samples (2 mL)of the subjects were collected.The expression of ASCA,anti-OmpC,anti-I2 and anti-Cbirl antibodies was detected with enzyme-linked immunosorbent assay (ELISA)kits.The diagnosis value of each antibody in IBD and the differential diagnostic value of in UC and CD were compared by receiver operating characteristic (ROC)curve.Results The area under the curve (AUC)of ASCA between IBD and the healthy control group,between CD group and UC group was 0.580 and 0.512, respectively;the accuracy in diagnosis was low.The AUC of anti-CBirl between IBD and the healthy control group was 0.617.There was no differential diagnosis significance of the other antibodies.The positive rate of ASCA in IBD group was 62.1 % (54/87),which was significantly higher than that in the control group (38.7%,24/62).The positive rates of anti-OmpC and anti-I2 in IBD group was significantly lower than those in the control group and the differences were statistically significant (both P <0.05).No difference was observed in positive rates of serum antibodies among the others groups (all P >0.05).The specificity,sensitivity,positive predictive value (PPV)and negative predictive value (NPV)of ASCA in differential diagnosis of CD and UC was 52.4%,66.7%,81 .48% and 33.33%,respectively.The specificity and sensitivity of anti-OmpC,anti-I2 and anti-CBirl in differential diagnosis of CD and UC was 81 .0% to 100.0% and 9.1 % to 37.9%,respectively.The specificity,sensitivity,PPV and NPV of double-positive ASCA and anti-I2 in the diagnosis of CD was 57.1 %,86.4%,82.6% and 50.0%, respectively.The positive rate of ASCA and anti-I2 in CD group was significantly higher than that in UC group (84.8%(56/66)vs 57.1 % (12/21 );χ2 =5 .633,P =0.018 ).Conclusions Positive ASCA has some significance in the diagnosis of patients with IBD in our country.The detection of anti-I2 can help to diagnose ASCA negative CD.Because of low sensitivity and positive rate,anti-OmpC and anti-CBirl have limited value in the diagnosis of IBD and the differential diagnosis of UC and CD in our country.

OBJECTIVETo study testing methods of seed quality, and provide a basis for establishing seed testing specification of Cyathula officinalis.

METHODReferring to the Specifications for Agricultural Seed Testing, the optimal testing methods of seed quality of C. officinalis were screened.

RESULT AND CONCLUSIONThe testing method for C. officinalis seed quality has been initially established. At least 8 g seeds should be sampled and passed through 20-mesh sieve for purity analysis. The phenotypic observation and size measurement were used for authenticity testing. The seeds were inoculated directly on PDA medium, cultured 5 days on 28 degrees C for seed health testing. The weight of 1 000 seeds was determined by using the 500-seed method. The water content of the seeds was determined under the higher temperature (133 +/- 2) degrees C for 3 hours. The seeds were dipped into 0.1% TTC solution 3 hours for determining viability. The seeds were cultured on pleated paper at 25 degrees C for 2-9 days for germination testing.

Objective To explore the correlation of total IgE and childhood atopic dermatitis (AD) in maternal serum and newborn cord blood, as well as its clinical significance of allergen testing. Methods Thirty-five cases diagnosed as AD (AD group) were selected, and other 35 children who were not diagnosed as AD (control group) were randomly selected from a birth cohort established in 2009—2011. The total IgE levels were detected by ELISA in maternal serum and newborn cord blood. The serum specific IgE antibody level was detected by quantitative immunoblotting method. Results The serum total IgE level was significantly higher in mother and newborn cord blood in AD group than that in control group (χ2=16.568 and 14.933, P<0.01). Compared to control group, there was a significantly higher positive rate of mother serum allergen includ?ing dust mites, house dust, ragweed pollen, song kind of pollen, poplar, surname and elm pollen, mould, shrimp, marine fish, in AD group (P<0.05). There was a significantly higher positive rate of artemisia pollen and fungi IgE in newborn cord blood in AD group (P<0.05). Conclusion The increased total IgE in maternal serum may play a predictive effect on infants suf?fering from AD. There is no obvious consistency in allergic state between mothers and infants.

Objective: To evaluate the prevalence and characteristics of Jackhammer esophagus (JE). Methods: From December 2015 to December 2018, the clinical data of 20 patients with JE in the People's Hospital of Yuhuan were retrospectively analyzed.The clinical data of JE patients with typical symptoms of proton pump inhibitor reactive gastroesophageal reflux disease (GERD) were evaluated.The differences between JE patients with or without GERD or allergic esophagus were analyzed, which including esophagogastroscopy (EGD), dynamic pH impedance monitoring of proton pump inhibitors and proton pump inhibitor tests. Results: Of 20 patients with JE, the average age was (55.86±3.23) years old, and BMI was (26.10±3.21)kg/m².Among JE patients, 10 cases (50.0%) were GERD positive, 2 cases (10.0%) were acid sensitive esophagus, and 8 cases (40.0%) were GERD negative.There were no statistically significant differences in heartburn (P=0.167), nausea (P=0.250), dysphagia (P=0.714) or non-cardiac chest pain (P=0.906) and their duration (P=0.319) among the three types of patients.It also affected the intake of proton pump inhibitor (P=0.377) and heartburn (P=0.494). The total number of reflux in patients with positive GERD caused by JE proton pump inhibitor was significantly increased (P=0.027). Conclusion JE has a low prevalence rate in patients with typical symptoms of GERD and proton pump inhibitor treatment response.In this study, only nearly half of the people were diagnosed as GERD positive, which indicates that additional objective tests are needed to stratify JE phenotypes.

Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.

Objective: To screen and identify serum protein biomarkers for the differential diagnosis between ischemic colitis (IC) and ulcerative colitis (UC) by tandem mass tag (TMT) combined with liquid chromatography/tandem mass spectrometry (LC-MS/MS). Methods: From January 2018 to January 2019, at the First Affiliated Hospital of School of Medicine of Zhejiang University, patients with UC or IC, and health controls, each 10 cases, were enrolled into UC group, IC group and normal control (NC) group, respectively. Fasting serum samples of all the subjects were collected. After removal of high-abundance protein, followed by proteolysis, peptide labeling and fractionating, the samples were then processed by mass spectrometry. The protein with TMT data of three groups was obtained and protein with TMT value 0 were removed. Heat map of protein was constructed. The differential protein was defined as the protein fold change over 1.5 or less than 0.67. The Reactome database was used to cluster the pathways of differential proteins among groups. Statistical methods included t test, hypergeometry test and corrected by BH multiple test. Results: A total of 357 serum proteins were identified by proteomic profiling. There were 27 differential proteins between the IC group and the NC group, including six up-regulated proteins and 21 down-regulated proteins. There were 228 differential proteins between the UC group and the NC group, including 75 up-regulated proteins and 153 down-regulated proteins. There were 49 differential proteins between UC group and IC group, including 22 up-regulated proteins and 27 down-regulated proteins. In the comparison of differential proteins between the NC group, IC group and UC group, only the expression of fibrin 3 was statistically significant (the fold change between UC and NC, between UC and IC, between IC and NC were 0.24, 0.46 and 0.53, respectively; t=-5.089, -7.298 and -3.919, all P<0.01). The results of pathway cluster analysis showed that in the comparison of differential proteins between IC group and NC group, only the platelet degranulation pathway was enriched, and 10 proteins were involved in this pathway (P<0.01). In the comparison of differential proteins between UC group and NC group, there were 58 pathways enriched, of which 38 proteins were involved in the platelet degranulation pathway, 16 proteins were involved in the initial complement trigger pathway, 13 proteins were involved in the complement cascade pathway, and 11 proteins were involved in antibody-mediated complement activation pathway (all P<0.01). In the comparison of differential proteins between UC group and IC group, three different pathways were obtained. Among them, nine proteins were involved in the platelet degranulation pathway, seven proteins were involved in the initial complement trigger pathway, and five proteins were involved in the complement cascade pathway (all P<0.01). Conclusions The difference in serum proteome between IC patients and UC patients was significant, and the differential proteins are mainly involved in platelet activation and complement activation. The candidate proteins identified in this study may be used as biomarkers for the differential diagnosis of UC and IC in the future.
