Objective To investigate the association of urinary phthalate metabolites with 4 high-density lipoprotein-cholesterol(HDL-C)-related inflammatory indicators[lymphocyte/HDL-C ratio(LHR),monocyte/HDL-C ratio(MHR),neutrophil/HDL-C ratio(NHR),and platelet/HDL-C ratio(PHR)],and to explain their possible biological mechanisms.Methods The 4 573 adult participants from the National Health and Nutrition Examination Survey(NHANES)were subjected,and then generalized linear regression(GLM),restricted cubic spline(RCS),and weighted quantile sum(WQS)regressions were performed to explore the potential associations of phthalates mono-exposures and mixed exposures,respectively,with the HDL-C-related inflammation metrics.Results Nine urinary phthalate metabolites were significantly positively associated with at least 1 inflammatory marker,while 1 metabolite(MEP)showed a negative association with an inflammatory indicator(LHR).Some exposure metabolites showed a nonlinear association with outcome inflammatory indicators.WQS regression revealed varying weight contributions of individual metabolite to each inflammatory outcome.Subgroup analyses indicated differential association effects of phthalates with HDL-C-related inflammatory metrics across gender,age,and BMI populations.Conclusion There are associations between phthalate exposure and HDL-C-related inflammation indicators,but further studies are needed to reveal the underlying mechanisms.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To analyze immune reconstitution and influencing factors in HIV infected men who have sex with men (MSM) with access to antiviral therapy (ART) in Guangxi Zhuang Autonomous Region (Guangxi) during 2005-2021.Methods:The data were collected from Chinese Disease Prevention and Control Information System. The study subjects were HIV infected MSM with access to the initial ART for ≥24 weeks in Guangxi from 2005 to 2021 and HIV RNA lower than the detection limit within 24 months. The proportion of infected MSM who had immune reconstitution after ART was calculated. Cox proportional hazard regression model was used to analyze the influencing factors of immune reconstitution. Software SPSS 24.0 was used for statistical analysis.Results:A total of 3 200 HIV infected MSM were enrolled, in whom 15.56 % (498/3 200) had no immune reconstitution, 14.78% (473/3 200) had moderate immune reconstitution, and the rate of complete immune reconstitution was 69.66% (2 229/3 200). The M ( Q1, Q3) of ART time for immune reconstitution was 12 (5, 27) months. Multivariate Cox proportional risk regression model analysis results showed that compared with those with initial ART at age ≥30 years, WHO clinical stage Ⅲ/Ⅳ illness, baseline BMI <18.50 kg/m 2 and baseline CD4 +T lymphocyte (CD4) counts <200 cells/μl, HIV infected MSM with initial ART at age <30 years, WHO clinical stageⅠ/Ⅱ illness, baseline BMI≥24.00 kg/m 2 and baseline CD4 counts ≥200 cells/μl were more likely to have complete immune reconstitution. Conclusions:In the HIV infected MSM in Guangxi, failures to achieve moderate and complete immune reconstitution were observed. Surveillance and ART regimen should be improved for key populations, such as those with older age and low baseline CD4 counts.

Objective:To construct an prediction model based on magnetic resonance imaging (MRI) machine learning algorithm and radiomics and investigate its application value in predicting lymphovascular invasion (LVI) status of rectal cancer without lymph node metastasis.Methods:The retrospective cohort study was conducted. The clinicopathological data of 204 rectal cancer patients without lymph node metastasis who were admitted to Gansu Provincial Hospital from February 2016 to January 2024 were collected. There were 123 males and 81 females, aged (61±7)years. All 204 patients were randomly divided into the training dataset of 163 cases and the testing dataset of 41 cases by a ratio of 8∶2 using the electronic computer randomization method. The training dataset was used to construct the prediction model, and the testing dataset was used to validate the prediction model. The clinical prediction model, radiomics model and joint prediction model were constructed based on the selected clinical and/or imaging features. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and the chi-square test or Fisher exact probability were used for comparison between the groups. Comparison of ordinal data was conducted using the nonparameter rank sum test. The inter-class correlation coefficient (ICC) was used to evaluate the consistency of the radiomics features of the two doctors, and ICC >0.80 was good consistency. Univariate analysis was conducted by corres-ponding statistic methods. Multivariate analysis was conducted by Logistic stepwise regression model. The receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC), Delong test, decision curve and clinical impact curve were used to evaluate the diagnostic efficiency and clinical utility of the model. Result:(1) Analysis of factors affecting LVI status of patients. Of the 204 rectal cancer patients without lymph node metastasis, there were 71 cases with positive of LVI and 133 cases with negative of LVI. Results of multivariate analysis showed that gender, platelet (PLT) count and carcinoembryonic antigen (CEA) were independent factors affecting LVI status of rectal cancer without lymph node metastasis in training dataset [ odds ratio=2.405, 25.062, 2.528, 95% confidence interval ( CI) as 1.093-5.291, 2.748-228.604, 1.181-5.410, P<0.05]. (2) Construction of clinical prediction model. The clinical prediction model was conducted based on the results of multivariate analysis including gender, PLT count and CEA. Results of ROC curve showed that the AUC, accuracy, sensitivity and specificity of clinical prediction model were 0.721 (95% CI as 0.637-0.805), 0.675, 0.632 and 0.698 for the training dataset, and 0.795 (95% CI as 0.644-0.946), 0.805, 1.000 and 0.429 for the testing dataset. Results of Delong test showed that there was no significant difference in the AUC of clinical prediction model between the training dataset and the testing dataset ( Z=-0.836, P>0.05). (3) Construction of radiomics model. A total of 851 radiomics features were extracted from 204 patients, and seven machine learning algorithms, including logistic regression, support vector machine, Gaussian process, logistic regression-lasso algorithm, linear discriminant analysis, naive Bayes and automatic encoder, were used to construct the prediction model. Eight radiomics features were finally selected from the optimal Gaussian process learning algorithm to construct a radiomics prediction model. Results of ROC curve showed that the AUC, accuracy, sensitivity and specificity of radiomics prediction model were 0.857 (95% CI as 0.800-0.914), 0.748, 0.947 and 0.642 for the training dataset, and 0.725 (95% CI as 0.571-0.878), 0.634, 1.000 and 0.444 for the testing dataset. Results of Delong test showed that there was no significant difference in the AUC of radiomics prediction model between the training dataset and the testing dataset ( Z=1.578, P>0.05). (4) Construction of joint prediction model. The joint prediction model was constructed based on the results of multivariate analysis and the radiomics features. Results of ROC curve showed that the AUC, accuracy, sensitivity and specificity of radiomics prediction model were 0.885 (95% CI as 0.832-0.938), 0.791, 0.912 and 0.726 for the training dataset, and 0.857 (95% CI as 0.731-0.984), 0.854, 0.714 and 0.926 for the testing dataset. Results of Delong test showed that there was no significant difference in the AUC of joint prediction model between the training dataset and the testing dataset ( Z=0.395, P>0.05). (5) Performance comparison of three prediction models. Results of the Hosmer-Lemeshow goodness-of-fit test showed that all of the clinical prediction model, radiomics prodiction model and joint prediction model having good fitting degree ( χ2=1.464, 12.763, 10.828, P>0.05). Results of Delong test showed that there was no signifi-cant difference in the AUC between the clinical prediction model and the joint prediction model or the radiomics model ( Z=1.146, 0.658, P>0.05), and there was a significant difference in the AUC between the joint prediction model and the radiomics model ( Z=2.001, P<0.05). Results of calibra-tion curve showed a good performance in the joint prediction model. Results of decision curve and clinical impact curve showed that the performance of joint prediction model in predicting LVI status of rectal cancer without lymph node metastasis was superior to the clinical prediction model and the radiomics model. Conclusions:The clinical prediction model is constructed based on gender, PLT count and CEA. The radiomics predictive model is constructed based on 8 selected radiomics features. The joint prediction model is constructed based on the clinical prediction model and the radiomics predictive model. All of the three models can predict the LVI status of rectal cancer with-out lymph node metastasis, and the joint prediction model has a superior predictive performance.

Objective:To explore the effect of clinical conventional fractionated dose radiation on the expression levels of immunogenic cell death (ICD) related proteins in patients with nasopharyngeal carcinoma (NPC).Methods:A total of 38 newly-treated NPC patients admitted to the Affiliated Cancer Hospital of Guizhou Medical University from November 2020 to December 2021 were enrolled, all of whom received induction chemotherapy and concurrent chemoradiotherapy, and another 20 healthy volunteers were selected as controls for a prospective study. The contents of ICD related proteins, namely calreticulin (CRT), high mobility group box 1 protein (HMGB-1) and heat shock protein 70 (HSP70) and the proportion of dendritic cell (DC) in the peripheral blood of patients were detected before treatment, after induction chemotherapy and after concurrent chemoradiotherapy, respectively. The correlation between the above indicators, general clinical data and short-term efficacy was analyzed by statistical methods such as t-test and analysis of variance (ANOVA). Results:The levels of HSP70 and HMGB-1 in peripheral blood of NPC patients before treatment were higher than those of healthy controls (both P<0.05). After concurrent chemoradiotherapy, the content of CRT was significantly higher than that before treatment ( P<0.05), whereas the difference before and after induction chemotherapy and the difference before and after concurrent chemoradiotherapy were not significantly correlated with the short-term efficacy of NPC patients. HSP70 level was significantly decreased after concurrent chemoradiotherapy ( P<0.001). There were no significant differences in the content of HMGB-1 after induction chemotherapy and concurrent chemoradiotherapy (both P>0.05). Conclusion:NPC patients receiving TPF regimen (docetaxel+cisplatin+fluorouracil) for induction chemotherapy and sequential cisplatin concurrent chemotherapy may induce ICD in NPC cells, and CRT has potential value in reflecting the clinical efficacy of NPC.

Objective:To analyze the trend of late-diagnosis of HIV-infected men who have sex with men (MSM) before and after the AIDS Conquering Project in Guangxi Zhuang Autonomous Region (Guangxi) and its influencing factors, in order to find out the population groups that need priority intervention at the present stage.Methods:The HIV-infected MSM in Guangxi from 2005-2021 were selected from the National Integrated HIV/AIDS Control and Prevention Data System. The Joinpoint 4.9.1.0 software was used to test the time trend of late-diagnosis and non-late-diagnosis cases, and logistic regression was applied to analyze the factors influencing the proportion of late-diagnosis at each stage.Results:From 2005 to 2021, 5 764 HIV-infected MSM were reported in Guangxi from 2005 to 2021, with an overall late-diagnosis of 28.45% (1 640 cases). Under the 2015 baseline data as the boundary, the proportion of late-diagnosis cases showed a trend of sharp decline followed by stabilization from 2005 to 2015, average annual percent change= -6.90% ( P<0.001). The effect of factors such as resident population, occupation as a farmer or worker, and sample originating from medical consultation on late-diagnosis changed considerably before and after the implementation of the project, and the factors influencing late-diagnosis at this stage were age, resident population, occupation as a farmer, worker or student. The factors influencing late-diagnosis at this stage are age, resident population, and occupation as a farmer, worker and a student. Conclusions:The proportion of late diagnosis cases of HIV-infected MSM in Guangxi decreased significantly before and after the project. However, late-diagnosis should not be neglected and precise prevention and control should be carried out for the resident population, farmers, workers or students.

Objective To conduct a retrospective study on the clinical efficacy with endoscopic linea alba plication (ELAP) in the treatment of postpartum diastasis recti abdominis muscles. Methods Clinical data was collected to study the patients with postpartum diastasis recti abdominis muscles treated by ELAP in our hospital from January 2018 to December 2021. The operation was performed successfully in 48 cases. One case was lost follow-up and 47 cases were included in this study. Mean age was (34.9±4.2) years with body mass index (BMI) (20.1±2.0) kg/m2. The index of patients included general data, intraoperative data and postoperative recovery. Follow-up was done through out-patient examination and B-mode ultrasonography until to March 2022. Results The inter-rectus distance (IRD) in umbilical area (M3) shown by ultrasound examination was (41.6±8.2) mm. There were 10 cases combined with umbilical hernia and 2 cases with linea alba hernia. ELAP was performed under general anesthesia. All hernia rings were closed by suturing. The operative time was (130.9±36.0) min. Visual analog scale was (1.2±0.6) on the 1st postoperative day with postoperative hospital stay (1.5±0.9) d. Two cases had mild seroma postoperatively with puncture and absorption under B-ultrasound guiding. Remaining cases were without operative complications such as bleeding and infection of incision. Followed up of 47 cases was completed in the period of median 15(12, 26) months. One case had mild pain in the operative site and cured after non-operative treatment. Ultrasound examination in the other case showed 57.0 mm of IRD in M3 area preoperative and normal in the follow-up of 1 month postoperative. However, there was mild recurrence on 3 months of follow-up showing IRD 21.0 mm. Conclusions ELAP could be considered safe and effective in the treatment of postpartum diastasis recti abdominis muscle.

ObjectiveTo determine the prevalence of ticks parasitic on domestic animals in Yiwu City of Zhejiang Province. MethodsWe monitored， identified and analyzed ticks parasitic on domestic animals in Yiwu in 2021. ResultsA total of 452 domestic animals were monitored， of which 306 were infected with ticks， suggesting a prevalence of 67.70%. A total of 2，603 ticks were captured， and the tick index was determined to be 5.76. The ticks were identified to belong to one family， four genera， and 10 species. Haemaphysalis longicornis was the dominant tick （59.16%）， followed by Rhipicephalus haemaphysaloides （26.32%） and Rhipicephalus microplus （6.45%）. Prevalence of ticks， tick index， and number of tick species were listed for domestic animals as follows： goats （74.37%， 7.45， 7 species）， yellow cattle （62.50%， 4.14，6 species）， and dogs （54.62%， 2.59， 8 species）. Moreover， goat was the main domestic animal infected with more than two tick species （25.99%）； H.longicornis （91.26%） was the species with most repated infections. The dominant species of ticks were H.longicornis （65.15%） and R.haemaphysaloides （29.42%） in goats， R.microplus （67.67%） and R.haemaphysaloides （20.69%） in yellow cattle， and H.longicornis （57.14%） and Haemaphysalis porcupines （21.10%） in dogs. However， seasonal fluctuation in tick index differed among goats， yellow cattle and dogs. The fluctuation in tick index in goats and dogs was consistent with that of H.longicornis， with a major peak in March and the minor peaks in September and October. The fluctuation in tick index in yellow cattle was consistent with that of R.microplus， with two peaks in April and August-September. In addition， larval ticks， nymphal ticks and adult ticks were caught in this study， among which nymphal ticks were most common. We found that single domestic animals were infected with ticks of the same species and different stages， which was more common in goats and those animals infected with H.longicornis. ConclusionTicks parasitic on domestic animals are common in Yiwu. Multiple species of ticks have been identified， with H.longicornis as the dominant species. It warrants further monitoring and countermeasures.
