Objective To investigate the effect and mechanism of rhubarb Tangluo pill on liver injury in type 2 diabetic rats.Methods ZDF(fa/fa)rats were given high-fat diet to induce type 2 diabetes model,and were randomly divided into model group,positive control group(0.18 g·kg-1 metformin)and experimental-L,-M,-H groups(0.54,1.08 and 2.16 g·kg-1 rhubarb Tangluo pill),with 8 rats in each group.Eight ZDF(fa/+)rats were selected as control group.The control group and model group were given equal volume of pure water once a day for 12 weeks.An oral glucose tolerance test(OGTT)was performed after administration.Fasting blood glucose level,body mass and liver mass of rats were measured and liver index was calculated.The contents of glutamic-pyruvic transaminase(GPT),glutamic oxalacetic transaminase(GOT),triglyceride(TG)and total cholesterol(TC)in serum were detected.The histomorphologic changes of liver were observed by hematoxylin-eosin(HE)staining and Masson staining.The protein expression of phosphorylated insulin receptor substrate 1(p-IRS1),phosphorylated protein kinase B(p-Akt)and glucose transporter 4(GLUT4)were detected by Western blotting.Results After administration,the fasting blood glucose levels of control group,model group,positive control group and experimental-H group were(4.71±0.45),(29.9±2.97),(15.28±4.52)and(13.84±1.55)mmol·L-1,respectively;the liver index were 2.31±0.46,4.03±0.18,3.37±0.23 and 3.38±0.24;the relative expression level of p-IRS1 protein were 1.00±0.36,4.00±0.11,1.62±0.27 and 1.90±0.17,respectively;the relative expression levels of p-Akt protein were 1.00±0.25,0.21±0.04,0.73±0.15 and 0.54±0.04,respectively;GLUT4 protein relative expression levels were 1.00±0.11,0.40±0.08,0.86±0.04 and 0.70±0.06,respectively.Compared with the model group,the above indexes in the experimental-H group were statistically significant(P＜0.01,P＜0.05).Conclusion Rhubarb Tanglu pill can effectively improve glycolipid metabolism and liver injury in type 2 diabetes mellitus,and its mechanism may be related to the activation of IRS1/Akt signaling pathway.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective:To automatically classify hypertensive heart disease (HHD) and hypertrophic cardiomyopathy (HCM) based on mul-titask learning algorithm using native T1 mapping images.Methods:A total of 203 patients admitted to Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University from January 2017 to December 2021 were enrolled, including 53 patients with HHD, 121 patients with HCM, and 29 patients with normal control (NC). Native T1 mapping images of all enrolled patients were acquired using MRI and processed by a multi-task learning algorithm. The classification performance of each model was validated using ten-fold crossover, confusion matrix, and receiver operator characteristic (ROC) curves. The Resnet 50 model based on the original images was established as a control.Results:The ten-fold crossover validation results showed that the MTL-1 024, MTL-64, and MTL-all models showed better performance in terms of area under the curve (AUC), accuracy, sensitivity, and specificity compared to the Resnet 50 model. In the classification task, the MTL-64 model showed the best performance in terms of AUC (0.942 1), while the MTL-all model reached the highest value in terms of accuracy (0.852 2). In the segmentation task, the MTL-64 model achieved the best results with the Dice coefficient (0.879 7). The confusion matrix plot showed that the MTL model outperforms the Resnet 50 model based on the original image in terms of overall performance. The ROC graphs of all MTL models were significantly higher than the original image input Resnet 50 model.Conclusions:Multi-task learning-based native T1 mapping images are effective for automatic classification of HHD and HCM.

Objective To explore the clinical characteristics of patients with alcoholic liver disease(ALD)of various traditional Chinese medicine(TCM)syndrome types.Methods A retrospective analysis was conducted in 129 patients with alcoholic liver disease who met the inclusion and exclusion criteria in Foshan Hospital of Traditional Chinese Medicine from 2018 to 2022.The general data of the patients as well as their TCM syndrome types and clinical information of liver and kidney function,blood lipid,liver transient elastography during the hospital visit were collected.The distribution of TCM syndrome types in ALD patients was analyzed,and the clinical characteristics of the ALD patients with various TCM syndrome types were explored.Results(1)Of the 129 patients,128(99.22%)were male and only one(0.78%)was female,the average age was(48.71±11.50)years old,and the average body mass index(BMI)was(23.82±3.98)kg·m-2.(2)Damp-heat accumulation syndrome was most common syndrome type in ALD patients,with a total of 70 cases(54.26%),and then came liver depression and spleen deficiency syndrome(24 cases,18.60%),internal obstruction of phlegm-damp syndrome(22 cases,17.05%),liver-kidney sufficiency syndrome(7 cases,5.43%),phlegm interweaved with blood stasis syndrome(3 cases,2.33%),and internal accumulation of blood stasis syndrome(3 cases,2.33%).(3)The analysis of clinical characteristics by non-parametric rank sum test showed that there were no statistically significant differences in BMI,alcohol consumption,aspartate aminotransferase(AST),gamma-glutamyltransferase(GGT),total bilirubin(TBIL),alkaline phosphatase(ALP),triglyceride(TG),liver stiffness measurement(LSM),and controlled attenuation parameter(CAP)which reflects the fat content of liver in ALD patients with various TCM syndrome types(P＜0.05 or P＜0.01).The prominent features were as follows:patients with the 4 types of liver depression and spleen deficiency,internal obstruction of phlegm-damp,phlegm interweaved with blood stasis,and internal accumulation of blood stasis had a BMI exceeding the standard(＞24 kg·m-2),whereas patients with damp-heat accumulation syndrome and liver-kidney deficiency syndrome,which accounted for 54.26%of the sample size,had a BMI within the normal range(23.03 kg·m-2 and 21.42 kg·m-2,respectively),and the BMI of these two types differed from that(26.44 kg·m-2)of the internal obstruction of phlegm-damp syndrome(P＜0.01),suggesting that more than half of the ALD patients had the normal BMI;moreover,the patients with internal obstruction of phlegm-damp also had the highest values of serum TG(2.69 mmol/L)and CAP(292 db/m)except for the highest BMI,indicating that patients with internal obstruction of phlegm-damp syndrome had a more serious degree of obesity and hepatic fat infiltration than those with other syndrome types;the levels of AST and GGT,which separately reflect the chronic inflammatory injury of liver and bile duct cell injury,were significantly increased in the patients with damp-heat accumulation syndrome and liver-kidney deficiency syndrome,and the LSM value of these two types of patients was also the highest in all of the syndrome types,the differences being all statistically significant(P＜0.05 or P＜0.01).Conclusion Damp-heat accumulation syndrome is the main TCM syndrome type of ALD patients,the degree of fatty infiltration of the liver and overweight of ALD patients are not corresponded to the severity of illness,and there are some differences in the clinical indicators of ALD patients with various TCM syndrome types.However,with cross reference to the data of the four diagnostic examinations of TCM and the clinical indicators,the accuracy of the TCM diagnosis of ALD is expected to be increased.

Objective:To explore the effect of TP53 mutation variant allele frequency(VAF)on the prognosis of diffuse large B-cell lymphoma(DLBCL)patients.Methods:This study included 155 patients with DLBCL who were first diagnosed in the People's Hospital of Xinjiang Uygur Autonomous Region from March 2009 to March 2022. Complete clinical data and paraffin-embedded tumor tissue samples were obtained,and DNA was extracted from tumor tissues.The gene mutation profile of DLBCL patients was detected and analyzed by second-generation sequencing technology.Kaplan-Meier method was used to analyze the mutation status of TP53 gene and the relationship between mutation VAF and OS.Cox regression univariate and multivariate analysis was use to analyze the independent factors affecting OS.A nornogram model for predicting 1,3,and 5 years OS in DLBCL patients were established to evaluated the performance of the model based on C-index and calibration curves.Results:The average value of TP53 mutation VAF in male DLBCL patients was significantly higher than that in female patients (P<0.05 ).Patients with TP53 mutantion had shorter OS than those with wild-type patients (P=0.030).The optimal VAF threshold for TP53 mutation based on OS stratification was 33.61％(P<0.001),and patients with TP53 mutation VAF≥34％had shorter OS than those with TP53 mutation VAF<34％and wild-type patients (P<0.001).Multivariate Cox analysis showed that TP53 mutation VAF≥34％ was an independent poor predictor of OS (HR=4.05,P<0.001),and IPI score ≥3 was an independent predictor of OS poor (HR=2.27,P=0.008).In combination with factors with independent prognostic significance obtained from multi-factor analysis,we constructed a nomogram model for predicting 1-year,3-year,5-year OS in DLBCL patients.The results showed that the C index of TP53-mutated VAF combined with IPI model was 0.743,which predicted the value of 1-year,3-year,and 5-year OS in DLBCL patients.Calibration curves show that the model has good agreement between predicted and actual survival of DLBCL patients at 1-year,3-year,and 5-year. Conclusion:TP53 mutant VAF has prognostic value in DLBCL patients,and TP53 mutant VAF≥34％ is an independent risk factor for OS in DLBCL patients.The prognosis model of TP53 mutation VAF combined with IPI nomogram constructed in this study has good predictive performance for DLBCL patients.

AIM: To analyze the effect of full-femtosecond small incision lenticule extraction(SMILE)on the treatment of high myopia based on propensity score matching.METHODS: A total of 48 cases(48 eyes)of high myopia patients who underwent SMILE surgery in our hospital from May 2019 to May 2021 were selected as the observation group, and 48 cases(48 eyes)of high myopia patients who underwent FS-LASIK surgery were matched using propensity score matching as the control group. Follow up for 6mo after surgery, the changes in cylindrical, central corneal thickness, uncorrected visual acuity(UCVA), corneal endothelial cell related indicators [percentage of hexagonal endothelial cells(6A), coefficient of variation(CV)of endothelial cell area, central corneal endothelial cell density(ECD)] and corneal biomechanical indicators [simulated Goldman intraocular pressure(IOPg), corneal hysteresis(CH), corneal resistance factor(CRF), corneal compensated intraocular pressure(IOPcc)] between the two groups were compared, and the incidence of complications in both groups of patients was recorded.RESULTS: Both groups of patients showed significant improvements in cylindrical and UCVA at 3 and 6mo after surgery, as well as decreased central corneal thickness, corneal endothelial cells, and corneal biomechanics related indicators. The changes in the observation group were more significant(all P<0.05). During the follow-up period, there was no significant difference in the incidence of complications between the observation group and the control group(8% vs. 17%, P>0.05).CONCLUSION: SMILE has a definite effect on patients with high myopia and is helpful to improve visual acuity.

Based on the Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3) signaling pathway, this study investigated the effect of medicated serum of Sparganii Rhizoma(SR) and Curcumae Rhizoma(CR) on the proliferation, apoptosis, migration, and secretion of inflammatory factors of ectopic endometrial stromal cells(ESCs). Specifically, human ESCs were primary-cultured. The effect of different concentration(5%, 10%, 20%) of SR-, CR-, and SR-CR combination-medicated serum, and AG490 solution(50 μmol·L~(-1)) on the proliferation of ESCs was detected by methyl thiazolyl tetrazolium(MTT) assay, and the optimal dose was selected accordingly for further experiment. The cells were classified into normal serum(NS) group, SR group(10%), CR group(10%), combination(CM) group(10%), and AG490 group. The apoptosis level of ESCs was detected by flow cytometry, and the migration ability was examined by wound healing assay. The secretion of interleukin(IL)-1β, IL-6, and tumor necrosis factor(TNF)-α was determined by enzyme-linked immunosorbent assay(ELISA). The protein levels of cysteinyl aspartate specific protei-nase-3(caspase-3), B-cell lymphoma(Bcl-2), and Bcl-2-associated X protein(Bax) and the levels of phosphorylated(p)-JAK2 and p-STAT3 were detected by Western blot. The results showed that the viability of ESCs cells was lowered in the administration groups compared with the blank serum group(P<0.01), especially the 10% drug-medicated serum, which was selected for further experiment. The 10% SR-medicated serum, 10% CR-medicated serum, and 10% CM-medicated serum could increase the apoptosis rate(P<0.01), up-regulate the protein expression of caspase-3 and Bax in cells(P<0.05 or P<0.01), down-regulate the expression of Bcl-2(P<0.01), decrease the cell migration rate(P<0.05 or P<0.01), and reduce the secretion levels of IL-1β, IL-6, and TNF-α(P<0.05 or P<0.01), and levels of p-JAK2 and p-STAT3(P<0.05 or P<0.01). Compared with the SR and CR groups, CM group showed low cell viability(P<0.01), high protein expression of caspase-3 and Bax(P<0.05 or P<0.01), and low protein expression of Bcl-2 and p-JAK2(P<0.05). After incubation with CM, the apoptosis rate was higher(P<0.05) and the migration rate was lower(P<0.01) than that of the CR group. The p-STAT3 protein level of CM group was lower than that of the RS group(P<0.05). The mechanism of SR, CR, and the combination underlying the improvement of endometriosis may be that they blocked JAK2/STAT3 signaling pathway, inhibited ESC proliferation, promoted apoptosis, weakened cell migration, and reduced the secretion of inflammatory factors. The effect of the combination was better than that of RS alone and CR alone.

OBJECTIVE: To investigate the mutational spectrum in young patients with diffuse large B-cell lymphoma (DLBCL) based on next generation sequencing (NGS), and to provide a basis for in-depth understanding of the molecular biological characteristics and accurate prognosis of young DLBCL. METHODS: From March 2009 to March 2021, 68 young DLBCL patients with complete initial diagnosis data from the Department of Hematology, The People's Hospital Xinjiang Uygur Autonomous Region were retrospectively analyzed, and their paraffin-embedded tissues were subjected to targeted sequencing analysis by NGS technology (including 475 Target genes), and the differences in gene mutation profiles and signaling pathways between high-risk patients with aaIPI ≥2 and low-intermediate risk patients with aaIPI <2 were compared. RESULTS: A total of 44 high-frequency mutation genes were detected in 68 young DLBCL patients. By comparing the high-frequency mutation genes in aaIPI high-risk group and low-intermediate risk group, it was found that CARD11 mutation in aaIPI high-risk group was significantly higher than that in low-intermediate risk group (P =0.002), while MGA mutation (P =0.037) only appeared in the aaIPI high-risk group, and SPEN mutation (P =0.004) only appeared in the aaIPI low-intermediate risk group. The high-frequency mutation genes and clinical indicators of the aaIPI high-risk group were included in the survival analysis, and the results showed that TP53 (P =0.009, P =0.027), POU2AF1 (P =0.003, P =0.006) and CCND3 (P =0.040, P =0.014) genes mutations were associated with worse PFS and OS, while B2M was associated with better PFS (P =0.014) and OS (P =0.013). Multivariate COX regression analysis showed that the TP53, POU2AF1 and CCND3 were independent risk factors for PFS（P ＝0.021，P =0.005，P =0.020） and OS（P ＝0.042，P =0.010，P =0.013）. CONCLUSION The aaIPI staging combination with molecular biology markers is more conducive to accurately judging the prognosis of young DLBCL patients. TP53, POU2AF1 and CCND3 mutations predict worse survival in the patients with the aaIPI high-risk group.

The modernization and development of traditional Chinese medicine has led to higher standards for the quality of traditional Chinese medicine products. The extraction process is a crucial component of traditional Chinese medicine production, and it directly impacts the final quality of the product. However, the currently relied upon methods for quality assurance of the extraction process, such as simple wet chemical analysis, have several limitations, including time consumption and labor intensity, and do not offer precise control of the extraction process. As a result, there is significant value in incorporating near-infrared spectroscopy (NIRS) in the production process of traditional Chinese medicine to improve the quality control of the final products. In this study, we focused on the extraction process of Xiao'er Xiaoji Zhike oral liquid (XXZOL), using near-infrared spectra collected by both a Fourier transform near-infrared spectrometer and a portable near-infrared spectrometer. We used the concentration of synephrine, a quality control index component specified by the pharmacopoeia, to achieve rapid and accurate detection in the extraction process. Moreover, we developed a model transfer method to facilitate the transfer of models between the two types of near-infrared spectrometers (analytical grade and portable), thus resolving the low resolution, poor performance, and insufficient prediction accuracy issues of portable instruments. Our findings enable the rapid screening and quality analysis of XXZOL onsite, which is significant for quality monitoring during the traditional Chinese medicine production process.

Chinese patent medicine (CPM) is an important part of traditional and Chinese medicine (TCM). Its quality has direct impact on the safety and effectiveness of clinical use. The quality standard is the pivotal approach to guarantee the quality of CPM. Due to the complex material basis, multitudinous quality influencing factors and unveiled active ingredients, dose-effect relationship and action mechanism, the investigation on quality standard faces many difficulties. This paper surveys the current quality status of CPM and the general situation of CPM standards. At present, the dosing problem has the crucial impact on the quality of CPM. The current quality standard system of CPM is confirmed and the limitations are indicated. Based on the above analysis, the principles and considerations on investigation of quality standard are proposed as follows: ① Adhere to safety as the bottom line, strengthen the risk-control ability of the standard of CPM; ② Adhere to theory of TCM and comprehensive quality, improve the integrative control level of the CPM standard; ③ Emphasize technological development and innovation, promote the quality control competence of CPM standard; ④ Facilitate planning and coordination, optimize the management of the CPM standard system; ⑤ Reinforce investigation on evaluation method, develop grade evaluation standard, accelerate high-quality development of CPM. Finally, the future perspective on investigation of CPM quality standard is prospected.
