ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome elements in type 2 diabetes mellitus （T2DM） patients based on maximum body mass index （maxBMI） and explore their association with complication risks. MethodsA retrospective cross-sectional study was used to collect clinical data from hospitalized T2DM patients， extracting age， gender， smoking history， alcohol consumption history， duration of disease， HbA1c level， complications， and TCM syndromes， and extracting the syndrome elements of disease location and disease nature based on their TCM syndromes. MaxBMI was calculated by telephone survey of patients' self-reported maximum body weight； patients with maxBMI ≥24 kg/m² were classified into spleen-heat syndrome group， and those with maxBMI ＜24 kg/m² were classified into consumptive-heat syndrome group. The distribution of TCM syndrome types and syndrome elements of patients in the two groups were analysed. Then the propensity score matching method was used to balance the baseline characteristics between the two groups and compare the differences in the distribution of syndrome types and syndrome elements and the risk of macrovascular and microvascular complications between the two groups. ResultsAmong the 1178 T2DM patients， syndrome elements in spleen-heat patients （1034 cases） were primarily located in the spleen （351 cases， 33.95%）， liver （240 cases， 23.21%）， and stomach （139 cases， 13.44%）， while in consumptive-heat patients （144 cases）， they were concentrated in the spleen （57 cases， 39.58%）， liver （34 cases， 23.61%）， and kidneys （17 cases， 11.81%）； regarding syndrome elements of disease nature， spleen-heat patients were predominantly characterized by qi deficiency （481 cases， 46.52%）， phlegm （353 cases， 22.73%）， and dampness （241 cases， 23.31%）， whereas consumptive-heat patients showed more qi deficiency （84 cases， 58.33%） and yin deficiency （44 cases， 30.56%）. After propensity score matching， 132 cases were included in each group， and no statistically significant differences were observed in the distribution of syndrome elements of disease location between the two groups （P＞0.05）， but the phlegm element was significantly more prevalent in spleen-heat patients than in consumptive-heat patients （P = 0.006）. Regarding the risk of complications， spleen-heat patients had a significantly higher risk of developing macrovascular complications compared to consumptive-heat patients （OR=2.04， P=0.010）， while no significant differences were found between groups in the occurrence of microvascular complications （P＞0.05）. ConclusionThe spleen-heat T2DM patients show a more frequent syndrome element of disease nature of phlegm， and a higher risk of developing macrovascular complications compared to consumptive-heat patients.

Objective To investigate the incidence of colorectal serrated lesions(SL)combined with advanced neoplasia(AN)and to analyze the risk factors for SL combined AN.Methods A total of 297 patients with colorectal polyps detected by endoscopy and pathologically suggestive of SL from 1st October 2021 to 30th September 2023 in the First People's Hospital of Huzhou.They were divided into combined group(n=33)and uncomplicated group(n=264)according to whether they were combined with AN or not,and the clinicopathologic differences between two groups were compared and the coexisting risk factors were analyzed.Results Age ≥ 50 years,male,history of polyps,polyp size and different SL subtypes were all risk factors for SL combined with AN,and the difference was statistically significant(P＜0.05).Logistic regression analysis revealed that age,male,history of polypos,and SL size were independent risk factors for SL combined with AN.Conclusion Males,older age,previous history of polyps,and larger SL lesions were more likely to have combined AN.

Objective:To analyze the F10 gene mutations in a Chinese pedigree affected with the deficiency of the hereditary coagulation factor X (FX), resulting from a new deletion mutation, and to study the associated molecular pathogenesis.Methods:Next generation sequencing (NGS) was performed to screen the genetic mutations in the proband which were then verified by Sanger sequencing. The FX activity (FX∶C) of probands and their family members was detected using the blood clotting method, and the mutation sites of the family members were analyzed using Sanger sequencing. The pathogenicity of the mutation site was predicted by using the online bioinformatics software, Mutation Taster. The SWISS-MODEL software was used for stimulating the three-dimensional models of the wild-type and mutant proteins for analyzing the influence of the mutation site on the structure and function of the proteins, and for analyzing the difference between the catalytic residues of the wild-type and the mutant proteins. The level of the F10 gene mRNA was quantitatively analyzed by qRT-PCR (quantitative reverse transcription polymerase chain reaction) method by constructing plasmids, transfecting human embryonic kidney 293T cells (HEK 293T), and analyzing the splicing of the mutated site by RT-PCR method. The levels of FⅩ∶Ag in cell lysates and cell culture media (both inside and outside the cells) were detected by the ELISA (enzyme linked immunosorbent assay) method.Results:A medium-grade factor X deficiency with a 36.42% FⅩ∶C ratio was detected in the proband by the coagulation method. NGS analysis demonstrated a heterozygous deletion mutation in exon 8:c.902_919del (p.Ala301_Glu306del) in the proband. Sanger sequencing analysis indicated that some members of the family (mother and grandfather) were also carriers of the corresponding deletion mutation. Online bioinformatics software predicted the pathogenic nature of the c.902_919del mutation, with a pathogenic score of 0.999. The 3D protein structure model analysis indicated that the c.902_919del mutation resulted in the disappearance of a segment of β-fold in the protein structure, thereby shortening the preceding segment of the β-fold and a subsequent loss of hydrogen bonds between adjacent amino acids with no significant difference in the side chain conformation of the key catalytic residues compared to the wild-type. mRNA splicing analysis indicated the absence of alternative splicing changes in the mutation, and qRT-PCR results indicated the absence of a statistically significant difference between the mRNA levels of F10 gene and wild-type mRNA in cells expressing c.902_919del mutant. The ELISA results indicated that there was no statistically significant difference in the FX∶Ag levels of the mutant cell culture medium and the lysate.Conclusions:In this pedigree, the heterozygous mutation in exon 8 of F10 gene (c.902_919del, p.Ala301_Glu306del) caused the hereditary factor Ⅹ deficiency.

Traditional Chinese medicine (TCM) has played an important role in the prevention and treatment of Coronavirus disease 2019 (COVID-19) epidemic in China. The integration of Chinese and Western medicine is an important feature of Chinese COVID-19 prevention and treatment. According to a series of evidence-based studies, TCM can reduce the infection rate of severe acute respiratory syndrome coronavirus 2 in high-risk groups. For patients with mild and moderate forms of COVID-19, TCM can relieve the related signs and symptoms, shorten the period of nucleic-acid negative conversion, and reduce conversion rate to the severe form of the disease. For COVID-19 patients with severe and critical illnesses, TCM can improve inflammatory indicators and blood oxygen saturation, shorten the hospital stay, and reduce the mortality rate. During recovery, TCM can improve patients' symptoms, promote organ function recovery, boost the quality of patients' life, and reduce the nucleic-acid repositive conversion rate. A series of mechanism research studies revealed that capability of TCM to treat COVID-19 through antiviral and anti-inflammatory effects, immune regulation, and protection of organ function via a multicomponent, multitarget, and multipathway approach.

Objective:To investigate the clinical characteristics, influencing factors and prevention and treatment measures of nosocomial infection in patients with acute myeloid leukemia (AML) (non-acute promyelocytic leukemia) after applying intermediate-high dose cytarabine (Ara-C) chemotherapy.Methods:The clinical data of 80 patients with AML treated with intermediate-high dose Ara-C in the Second Hospital of Shanxi Medical University from March 2013 to January 2020 were analyzed retrospectively. The clinical features of nosocomial infection were summarized and the influencing factors of infection were analyzed by using multivariate logistic regression.Results:A total of 80 patients received 198 times of chemotherapy, and the infection rate was 72.7% (144/198). Infection sites mainly included respiratory tract infection, pulmonary infection, gastrointestinal infection. A total of 45 strains of pathogenic bacterias were detected, among which Gram negative bacilli accounted for 55.6% (25/45), Gram positive cocci accounted for 24.4% (11/45), fungi accounted for 8.9% (4/45) and viruses accounted for 11.1% (5/45). There were no significant differences in infection rate, hospitalization time, neutrophils recovery time and hospitalization expenses between the sterile laminar flow ward and the general ward (all P > 0.05). Multivariate logistic regression analysis showed that infection during induction chemotherapy was independent risk factor of infection ( OR = 5.076, 95% CI 1.978-13.022, P =0.001), and antibiotic prevention was independent protective factor of nosocomial infection ( OR = 0.332, 95% CI 0.136-0.803, P = 0.014). Conclusions:The infection rate of AML patients receiving intermediate-high dose Ara-C chemotherapy is high. During the treatment, we should be alert to the infection during induction chemotherapy and use antibiotics to prevent it in time. For patients undergoing intermediate-high dose Ara-C chemotherapy, strengthening the environmental cleanliness of general wards may achieve the same preventive effect as that of sterile laminar flow wards.
