ObjectiveTo investigate the prevalence of high-risk HPV infection among women in Kashgar area， analyze related risk factors， conduct follow-up and health education interventions for positive cases in the past three years， and assess intervention outcomes to improve HPV screening awareness and reduce cervical cancer incidence. MethodsThis study randomly selected 571 women from Kashgar who underwent HPV screening as part of a health check-up in the First People’s Hospital of Kashgar between January 2021 and June 2023. High-risk HPV-DNA was detected using the PCR-RDB method. Based on the test results， participants were divided into HPV-negative and HPV-positive groups， and the infection rates and associated risk factors were analyzed. Additionally， follow-up was conducted for women who tested positive for high-risk HPV during the screening to assess the effectiveness of health management interventions. ResultsFrom 2021 to 2023， the high-risk HPV positive rate among women in Kashgar showed a year-on-year decline， recorded at 19.15%， 16.43%， and 11.30%， respectively （P<0.001）， with a total of 3，921 cases （16.13%） testing positive for high-risk HPV during this period. Uyghur women had a significantly higher infection rate compared with those of Han nationality and other ethnic minorities （P<0.05）. Risk factors included age， age at first sexual activity， number of sexual partners， contraceptive methods， and a history of vaginal inflammation （P<0.05）. Health management interventions significantly improved participants’ awareness scores regarding cervical cancer prevention and the proportion of women voluntarily receiving HPV vaccination （P<0.05）. ConclusionsHigh-risk HPV infection among Uyghur women in Kashgar area is relatively high， with single infection of HPV-16 and HPV-52 and mixed infections of HPV-16 +HPV-52 and HPV-16 +HPV-58 being predominant. Risk factors include age at first sexual activity， number of sexual partners， contraceptive methods， and history of vaginal inflammation. Through triple-education interventions， the incidence of cervical cancer in Kashgar has been effectively reduced， and standards for primary-level diagnosis， treatment， and health supervision have been improved.

Lianggesan was first recorded in Taiping Huimin Heji Jufang， which was composed of Rhei Radix et Rhizoma， Natrii Sulfas， Gardeniae Fructus， Forsythiae Fructus， Scutellariae Radix， Glycyrrhizae Radix et Rhizoma（GRR）， Menthae Haplocalycis Herba， Lophatheri Herba and Mel. It was clinically applied to treat fire-heat syndrome in the upper and middle Jiao， and the curative effect was positive. In this study， the bibliometric method was used to conduct a detailed textual research on the formula name， medicinal composition， dosage evolution， origin and processing， functional indications and other aspects of Lianggesan. Research revealed that Lianggesan has six other names， such as Lianqiao Yinzi， Lianqiao Jiedusan， Jufang Lianggesan， Jiegu Lianggesan， Hejian Lianggesan and Qingji Lianggesan. Based on the edition of Taiping Huimin Heji Jufang， an analysis of the evolution of its formula composition revealed that the missing Chinese medicines were predominantly bamboo leaves and honey， while the added Chinese medicines were primarily supplements introduced to address changes in disease manifestations. After textual research， the dosage for one dose of Lianggesan from Taiping Huimin Heji Jufang was as follows：826 g of Rhei Radix et Rhizoma， 826 g of Natrii Sulfas， 826 g of GRR， 413 g of Gardeniae Fructus， 413 g of Menthae Haplocalycis Herba， 413 g of Scutellariae Radix， and 1652 g of Forsythiae Fructus. Decocting method was as following：Grinding the Chinese medicines into coarse powder（2-4 mm）， taking 8.16 g per dose， adding 300 mL of water， along with 2 g of Lophatheri Herba and 5 g of Mel， and decocting to 140 mL. The residue was removed and taken warmly 30 min after meals. It was recommended to take it three times daily until improvement was achieved. The origins of the 9 Chinese medicines were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. Except for GRR， which required single frying（stir-frying）， the remaining medicines were all raw products. The description of the function of this formula in ancient books was summarized as purging fire and promoting bowel movements， clearing heat from the upper body and purging the lower body， and the main syndromes included facial redness， tongue swelling， red eyes， etc. In modern applications， the formula is primarily used for respiratory and digestive system diseases， including acute lung injury， chronic obstructive pulmonary disease， herpetic angina and aphthous stomatitis， covering 142 types of diseases. In summary， this paper can provide a basis for further research and development of Lianggesan through the literature review and key information combing.

BACKGROUND: Over 20 million colonoscopies are performed in China annually. An automatic clinical decision support system (CDSS) with accurate semantic recognition of colonoscopy reports and guideline-based is helpful to relieve the increasing medical burden and standardize the healthcare. In this study, the CDSS was built under a hierarchical-label interpretable classification framework, trained by a state-of-the-art transformer-based model, and validated in a multi-center style. METHODS: We conducted stratified sampling on a previously established dataset containing 302,965 electronic colonoscopy reports with pathology, identified 2041 patients' records representative of overall features, and randomly divided into the training and testing sets (7:3). A total of five main labels and 22 sublabels were applied to annotate each record on a network platform, and the data were trained respectively by three pre-training models on Chinese corpus website, including bidirectional encoder representations from transformers (BERT)-base-Chinese (BC), the BERT-wwm-ext-Chinese (BWEC), and ernie-3.0-base-zh (E3BZ). The performance of trained models was subsequently compared with a randomly initialized model, and the preferred model was selected. Model fine-tuning was applied to further enhance the capacity. The system was validated in five other hospitals with 3177 consecutive colonoscopy cases. RESULTS: The E3BZ pre-trained model exhibited the best performance, with a 90.18% accuracy and a 69.14% Macro-F1 score overall. The model achieved 100% accuracy in identifying cancer cases and 99.16% for normal cases. In external validation, the model exhibited favorable consistency and good performance among five hospitals. CONCLUSIONS The novel CDSS possesses high-level semantic recognition of colonoscopy reports, provides appropriate recommendations, and holds the potential to be a powerful tool for physicians and patients. The hierarchical multi-label strategy and pre-training method should be amendable to manage more medical text in the future.

OBJECTIVES: To investigate the incidence of myocardial injury in children with rotavirus-induced diarrhea, analyze its risk factors, and develop a predictive model for myocardial injury. METHODS: A retrospective analysis was conducted on 203 children diagnosed with rotavirus infection at the Suzhou Wujiang District Children's Hospital from January 2021 to December 2023. The children were divided into groups based on the presence or absence of myocardial injury. Basic information and laboratory indicators at admission were collected and compared between the two groups. LASSO regression was used to screen potential risk factors, followed by multivariate logistic regression to evaluate independent factors. A nomogram model was established and validated. RESULTS: Out of 203 children with rotavirus infection, 53 cases (26.1%) showed myocardial injury. Age, severe dehydration, metabolic acidosis, red cell distribution width, and blood sodium were closely associated with myocardial injury in children with rotavirus-induced diarrhea (P<0.05). The area under the receiver operating characteristic curve for the predictive model of myocardial injury was 0.841 (95%CI: 0.777-0.905), with a sensitivity of 73.6% and specificity of 85.3%. The model curve closely fit the ideal diagonal line. Decision curve analysis showed that using the model for prediction resulted in the highest net benefit when the probability threshold was 0.18-0.98. CONCLUSIONS The model developed in this study can predict the risk of myocardial injury in children with rotavirus-induced diarrhea.

OBJECTIVE: To investigate the effect of laparoscopic high ligation of spermatic cord vein in patients with chronic prostatitis and varicocele prostatitis. METHODS: A total of 90 varicocele patients were selected from January 2016 to December 2020, including 33 patients with chronic prostatitis. Changes of white blood cell count, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score and serum testosterone level in the expressed prostate secretion (EPS) were observed before and after the operation of laparoscopic high ligation of spermatic vein. RESULTS: All patients were followed up three months after the surgery. There was no significant difference in the white blood cell counts in EPS, NIH-CPSI score, and serum testosterone level in patients with varicocele-only who underwent high ligation surgery after the operation. However, the white blood cell count in the EPS of patients with chronic prostatitis was lower than that before 3 months of operation ( ［12.39±4.23］×109/L vs ［21.36±5.05］×109/L). The NIH-CPSI score was significantly lower than that before operation ( ［12.71±6.21］ vs ［26.76±8.43］). And the serum testosterone level was higher than that before operation (［4.34±1.77］ng/ml vs ［2.36±1.05］ng/ml). CONCLUSION Laparoscopic high ligation of the spermatic vein in patients with chronic prostatitis and varicocele could effectively reduce the number of white blood cells in the EPS, boost the level of serum testosterone and improves symptoms of chronic prostatitis.

Chronic pain, frequently comorbid with neuropsychiatric disorders, significantly impairs patients' quality of life and functional capacity. Accumulating evidence implicates the chemokine CCL2 and its receptor CCR2 as key players in chronic pain pathogenesis. This review examines the regulatory mechanisms of the CCL2/CCR2 axis in chronic pain processing at three hierarchical levels: (1) Peripheral Sensitization: CCL2/CCR2 modulates TRPV1, Nav1.8, and HCN2 channels to increase neuronal excitability and CGRP signaling and calcium-dependent exocytosis in peripheral nociceptors to transmit pain. (2) Spinal Cord Central Sensitization: CCL2/CCR2 contributes to NMDAR-dependent plasticity, glial activation, GABAergic disinhibition, and opioid receptor desensitization. (3) Supraspinal Central Networks: CCL2/CCR2 signaling axis mediates the comorbidity mechanisms of pain with anxiety and cognitive impairment within brain regions, including the ACC, CeA, NAc, and hippocampus, and it also increases pain sensitization through the descending facilitation system. Current CCL2/CCR2-targeted therapeutic strategies and their development status are discussed, highlighting novel avenues for chronic pain management.

Objective:To investigate the differences in clinical outcomes of septic children with varying serum zinc levels,and to analyze the relationship between reduced serum zinc levels and organ dysfunction as well as 28-day mortality in septic children.Methods:This study conducted a retrospective analysis of clinical data from pediatric patients diagnosed with sepsis or septic shock in the Department of critical care medicine of the children's Hospital of Soochow University between January 2017 and December 2022.Clinical characteristics,organ dysfunction,and prognosis were compared between two groups:children with low serum zinc levels and those with normal zinc levels.Results:The serum zinc level of septic children within 24 hours of admission was 9.60(5.52,13.80)μmol/L,with 50.54%(94/186)of the children exhibiting low serum zinc levels(<10.07 μmol/L).Compared to the normal serum zinc group,the low serum zinc group had a significantly lower Pediatric Critical Illness Score(PCIS)[(78.71±9.35)vs.(85.12±8.51),P=0.005]and higher 28-day mortality(46.80%vs.14.13%,P<0.001).The low serum zinc group also had a higher proportion of invasive mechanical ventilation(64.89%vs.47.82%,P=0.019),renal replacement therapy(15.59%vs.3.26%,P=0.003),and use of vasoactive drugs(56.38%vs.30.43%,P<0.001).The rate of underlying conditions in the low serum zinc group was significantly higher than that in the normal serum zinc group(57.44%vs.36.95%,P=0.005).Additionally,the low serum zinc group had a higher incidence of disseminated intravascular coagulation(DIC),respiratory failure,acute kidney injury,shock,and multiple organ dysfunction syndrome(MODS)compared to the normal serum zinc group(P<0.05).Serum zinc levels had predictive value for 28-day mortality in septic children(AUC=0.813;95%CI:0.725～0.902;P<0.001).A serum zinc level of less than 6.950 μmol/L predicted the death of septic children with a sensitivity of 0.618 and a specificity of 0.902.Conclusion:Sepsis in children is commonly associated with low serum zinc levels,especially in those with underlying conditions such as hematologic and oncologic disorders.Sepsis patients hypozincemia with a higher incidence of DIC,respiratory failure,acute kidney injury,shock,and MODS.A serum zinc level below 6.95 μmol/L serves as a significant predictor of 28-day mortality in children with severe sepsis.

Objective:To explore the characteristics of brain dynamic activity in patients with schizophrenia by using functional magnetic resonance imaging(fMRI).Methods:Forty-three patients with schizophrenia and 31 normal controls were recruited and under fMRI scanning.The Positive and Negative Symptom Scale(PANS)was used to assess the severity of clinical symptoms.The DPABI software were used to compute dReHo and dFC.Granger causality analysis was used to calculate the effective connectivity between the significant brain regions of dReHo and the whole brain.Two sample t-test was performed to compare the difference of dReHo and dFC be-tween patients with schizophrenia and normal controls.Results:The dReHo of left postcentral gyrus(LPG)(P＜0.01,cluster-level FWE corrected)in patients with schizophrenia was decreased.The Dfc was increased between left postcentral and left middle frontal gyrus,left superior medial frontal gyrus,right calcarine,left medial cingulum gyrus,right supplementary motor area(P＜0.01,uncorrected).Compared with normal controls,patients with schiz-ophrenia showed decreased effective connectivity from LPG to right putamen.Conclusion:It suggests that the ab-normal functional activity of the postcentral gyrus mightcontribute to the neural physiopathology in patients with schizophrenia.

Plain combined with three-phase contrast-enhanced CT is the most commonly used imaging technique for the diagnosis of renal masses, and it also plays an important role in predicting the malignancy and aggressiveness of renal tumors. The pathological findings of renal tumors are important in determining treatment options as well as prognosis. This article reviews current research and summarizes common CT variables for renal tumors, including tumor diameter, growth rate, enhancement characteristics, tumor margins, the proportion of cystic components, and variables related to the R. E.N.A.L. score. This paper aims to analyze the role of these variables in predicting the pathological malignancy and aggressiveness of the renal tumor.

Objective:To analyze the characteristics and its influencing factors of occupational injury among clinical nuclear medicine staff, and to put forward suggestions for formulating relevant radiation protection intervention measures.Methods:In March 2022, a study was conducted involving 12 medical institutions engaged in nuclear medicine in Gansu Province. The occupational health examination data of 1451 clinical nuclear medicine staff were analyzed. The study subjects were divided into two groups based on the median annual effective dose of external exposure in 2022: Group A (annual effective dose ≤0.2 mSv, n=927) and group B (annual effective dose >0.2 mSv, n=524). The effects of annual effective dose, age, seniority, gender and occupational category on occupational health of clinical nuclear medicine staff were analyzed. Classification variables between groups were compared with Pearson χ2 test. Multivariate logistic regression was used to analyze the influencing factors of the abnormal results. Results:The abnormal rates of white blood cell count (WBC), red blood cell count (RBC) and hemoglobin (HGB) in female clinical nuclear medical staff were higher than those in males, and the differences were statistically significant ( P<0.001). The abnormal rates of WBC and HGB in clinical nuclear medicine staff of different occupational categories were statistically significant ( P<0.05). The abnormal rates of RBC and HGB of clinical nuclear medicine staff in annual effective dose group B were higher than those in group A, and the differences were statistically significant ( P<0.05). Multivariate logistic regression results showed that the abnormal risks of RBC in annual effective dose group B was 2.465 times of that in group A, the abnormal risks of RBC, WBC and HGB in females were 9.354, 2.939 and 6.760 times of those in males, respectively. The abnormal risk of WBC in the radiotherapy group was 2.334 times of that in general radiotherapy group. The abnormal risk of lens in nuclear medicine group was 2.459 times of that in general radiotherapy group. The abnormal risk of ECG and lens in ≥35 years old age group were 1.814 times and 1.969 times of those in <35 years old age group, respectively. The abnormal risk of lens of the ≥10 working years group was 1.899 times of that in the <10 working years group. The risk of lymphocyte micronucleus abnormality in the interventional group was 1.481 times of that in the general radiotherapy group, the risk of lymphocyte micronucleus abnormality in females was 2.215 times of that in males. The risk of lymphocyte micronucleus abnormality and lymphocyte chromosome aberration in ≥35 years old age group were 2.552 and 2.266 times of those in <35 years old age group, respectively. The risk of lymphocyte micronucleus abnormality in the group with≥10 working years was 1.443 times of that in<10 working years group ( P<0.05) . Conclusion:Long-term low-dose ionizing radiation has a certain effect on the lens and genetic indexes of clinical nuclear medicine staff.
