ObjectiveTo explore the clinical efficacy and safety of Da Chaihutang （DCH） for the treatment of sepsis with Yang syndrome. MethodsA total of 70 patients suffering from sepsis with Yang syndrome were randomly divided into an observation group and a control group， with 35 cases in each group. They both received standard Western medicine treatment. The observation group was additionally given a dose of DCH， which was boiled into 100 mL and taken twice. The control group was additionally given an equal volume and dosage of warm water. The intervention lasted for three days. The 28-day all-cause mortality and the changes in the following indicators before and after intervention were compared between the two groups， including sequential organ failure assessment （SOFA）， acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ） score，white blood cell （WBC），the percentage of neutrophils （NEU%），C-reactive protein （CRP），procalcitonin （PCT），alanine transaminase （ALT），aspartate transaminase （AST），total bilirubin （TBil），creatinine （Cr），blood urea nitrogen （BUN），acute gastrointestinal injury （AGI） grade，gastrointestinal dysfunction score （GDS），serum intestinal fatty acid-binding protein （iFABP）， citrulline （CR），platelet （PLT），prothrombin time（PT），activated partial thromboplastin time （APTT），fibrinogen （Fib），international normalized ratio （INR），and D-dimer （D-D）. ResultsThere was no significant difference between the two groups regarding 28-day all-cause mortality. After the intervention，SOFA，WBC，PCT，and Cr were significantly decreased， and PLT was significantly increased in the control group （P<0.05）. SOFA，APACHE Ⅱ，NEU%，CRP，PCT，ALT，AST，Cr，BUN，AGI grade，GDS，and serum iFABP and CR were significantly improved in the observation group （P<0.05）. After the intervention，APACHE Ⅱ，PCT，AGI grade，GDS，and serum iFABP in the observation group were significantly lower than those in the control group ，while CR and PLT were higher （P<0.05，P<0.01）. There were significant differences regarding the gap of SOFA，APACHE Ⅱ，AST，TBil，AGI grade，GDS，iFABP，CR， and PLT between the two groups （P<0.05，P<0.01）. There were slight differences regarding PT，APTT，Fib，INR，and D-D between the two groups，which were in the clinical normal range. ConclusionOn the basis of Western medicine， DCH helped to reduce sepsis severity and improved multiple organ dysfunction with high clinical efficacy and safety， but further research on its impact on the prognosis of patients with sepsis is still required.

AIM: To analyze the recovery of stereopsis and its influencing factors in children with intermittent exotropia(IXT)after binocular vision training.METHODS: A total of 166 cases of IXT children who were treated in our hospital from October 2021 to October 2023(2 cases lost their follow-up, and 164 cases were finally included)were included as the research object, taking 36 cases with no stereopsis after binocular vision training in eye position correction surgery as no stereopsis group, and other 128 cases as stereopsis group. All the children underwent eye position correction surgery under general anesthesia, and all received binocular vision training for 6 mo after surgery. The recovery of stereoscopic vision of IXT children after binocular vision training was counted, and the influencing factors of stereoscopic vision recovery of IXT children after binocular vision training were analyzed by single factor and multi-factor Logistic regression analysis.RESULTS: The incidence of postoperative no stereopsis was 22.0%. The proportion of children with an age ≥9 years old, course of disease ≥1 a and anisometropia in the group without stereoscopic vision after operation was larger than the group with stereoscopic vision(all P<0.05). Multivariate Logistic regression analysis showed that the course of disease ≥1 a, age ≥9 years old and anisometropia were independent influencing factors for the recovery of stereoscopic vision in IXT children after binocular vision training(OR=1.470, 1.626, 1.539, all P<0.05).CONCLUSION: Age ≥9 years old, course of disease ≥1 a, and anisometropia are the independent influencing factors of stereopsis recovery of IXT children after binocular vision training. Therefore, targeted intervention measures can be given to high-risk children to improve the stereopsis recovery of IXT children after binocular vision training.

Objective To investigate the value of short diameter of lymph nodes combined with neutrophil to lymphocyte ratio(NLR)in evaluating lymph node metastasis of cervical cancer by enhanced CT.Methods A total of 82 patients with cervical cancer were selected and divided into metastatic group(n=13)and non-metastatic group(n=69)according to whether lymph node metas-tasis occurred.The clinicopathological features of the two groups were compared,and the relationship between NLR and clinicopath-ology was analyzed.Logistic regression was used to analyze the influencing factors of lymph node metastasis of cervical cancer.The short diameter of lymph nodes and serum NLR were compared between the two groups.Receiver operating characteristic(ROC)curve,DeLong test and compare the area under the curve(AUC)analysis was used to evaluate the value of lymph node metastasis in cervical cancer.The diagnostic efficacy of the above indexes were compared between the two groups.Results The short diameter of lymph nodes and NLR in the metastatic group were(0.686±0.120)cm and 2.23±0.41 respectively,while thosein the non-metastatic group were(0.602±0.106)cm and 1.76±0.30 respectively.The difference between the two groups was statistically signifi-cant(P＜0.05);There was no significant difference in age,growth pattern and vascular infiltration between the metastatic group and the non-metastatic group(P＞0.05).There were significant differences in clinical stage,maximum diameter of tumor,NLR and short diameter of enhanced CT lymph nodes(P＜0.05);The NLR was related to clinical stage,pelvic lymph node metastasis,and the short diameter of lymph nodes on enhanced CT scan(P＜0.05);Clinical stage Ⅲ,maximum diameter of tumor≥4 cm,NLR＞1.80 and short diameter of enhanced CT lymph nodes≥0.632 cm were independent risk factors for cervical cancer lymph node metastasis(P＜0.05);The ROC curve analysis showed that the AUC of the combined detection of cervical cancer was 0.871,higher than that of the enhanced CT lymph nodes short diameter and serum NLR(0.645,0.795),and its specificity was better than that of the independent detection.The best cutoff values of the enhanced CT lymph nodes short diameter and serum NLR were 0.630 cm and 1.91,respectively.Conclusion The short diameter of lymph nodes and the serum NLR can predict lymph node metastasis of cervical cancer,and the combined detection can improve the evaluation efficiency.

Objective To analyze the correlation between digital mammography features,lymphocyte to monocyte ratio(LMR)and prognosis in patient with invasive breast cancer,and to explore the prognostic value of digital mammography features and LMR in invasive breast cancer.Methods Ninety-six patients with invasive breast cancer were selected.The data of digital mammography features and serum LMR levels were analyzed.The patients were followed up after discharge.According to different prognosis,all patients were divided into good prognosis group(68 cases)and poor prognosis group(28 cases).Spearman was used to analyze the correlation of digital mammography features,LMR level and prognosis of patients.Receiver operating characteristic(ROC)curve was drawn to analyze the prognostic value of digital mammography features and LMR level.Results The spicule sign and proportion of calcifica-tion in the poor prognosis group was significantly higher than that in the good prognosis group,the maximum diameter of tumor was significantly larger than that in the good prognosis group,and the serum LMR level was significantly lower than that in the good prognosis group(P＜0.05).Spearman correlation analysis showed that spicule sign,proportion of calcification and maximum diame-ter of tumor were positively correlated with poor prognosis of invasive breast cancer(P＜0.05).Serum LMR level was negatively correlated with poor prognosis of invasive breast cancer(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of spicule sign,calcification and tumor maximum diameter combined with LMR level to evaluate the prognosis of invasive breast cancer was 0.927,the sensitivity was 89.71％,and the specificity was 82.14％,which were significantly higher than those of each index alone.Conclusion Digital mammography and serum LMR levels may be closely related to the prognosis of patients with invasive breast cancer,and spicule sign,calcification,tumor maximum diameter combined with serum LMR may be of significant prognostic value in invasive breast cancer.

ObjectiveTo investigate whether Jiedu Huoxue prescription can induce macrophage autophagy and inhibit inflammatory response to stabilize vulnerable plaques of atherosclerosis （AS） by regulating phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. MethodThirty ApoE^-/- mice fed with high-fat diet were randomly assigned into model， low-， medium-， and high-dose （5.35， 10.7， and 21.4 g·kg^-1·d^-1， respectively） Jiedu Huoxue prescription （Chinese medicine）， and rapamycin （2 mg·kg^-1·d^-1） groups. Six ApoE^-/- mice fed with common diet were used as the control group， and 6 C57BL/6J mice fed with common diet as the blank group. The drugs or equal volume of normal saline were administrated by gavage after 7 weeks of modeling， and the treatment lasted for 4 weeks. The serum levels of lipids and inflammatory cytokines ［monocyte chemoattractant protein-1 （MCP-1） and interleukin-6 （IL-6）］ were measured. Hematoxylin-eosin （HE） staining was employed to observe the pathological changes of the vascular wall of the aortic root. Immunohistochemistry was employed to detect the expression of macrophages/monocytes monoclonal antibody （MOMA-2） and α-smooth muscle actin （α-SMA）. Transmission electron microscopy was employed to count the autophagosomes in the aorta， and Western blot to determine the protein levels of Beclin-1， LC3， PI3K， Akt， and mTOR. ResultCompared with the control group， the model group showed elevated serum levels of lipids， MCP-1， and IL-6 （P<0.05）， inhibited expression of MOMA-2 and α-SMA （P<0.05， P<0.01）， up-regulated protein level of Beclin-1 （P<0.05）， and down-regulated protein levels of PI3K， Akt， and mTOR （P<0.05， P<0.01）. The model group presented obvious atherosclerotic plaques on the inner wall of the aorta， infiltration of inflammatory cells in the plaque， thickened and disarranged vascular intima where the plaque was attached， decreased autophagosomes and mitochondria， and destroyed mitochondrial structure. Chinese medicine and rapamycin groups showed lower levels of total cholesterol， triglycerides， low-density lipoprotein cholesterol， MCP-1， and IL-6 （P<0.05）， higher level of high-density lipoprotein cholesterol （P<0.05）， inhibited expression of MOMA-2 and α-SMA （P<0.05， P<0.01）， higher protein levels of Beclin-1 and LC3Ⅱ （P<0.05， P<0.01）， and lower protein levels of PI3K， Akt， and mTOR （P<0.05， P<0.01） than the model group. Moreover， Chinese medicine and rapamycin groups showed only a small number of atherosclerotic plaques on the inner wall of the aorta， reduced infiltration of inflammatory cells and thickness of the blood vessel wall， and increased autophagosomes and autophagic lysosomes. ConclusionJiedu Huoxue prescription can improve lipid metabolism， enhance macrophage autophagy， and reduce AS-induced inflammation to improve the stability of vulnerable plaques in AS mice by inhibiting the PI3K/Akt/mTOR signaling pathway.

Objective The knowledge of cervical cancer prevention and control，the cognition of human papillomavirus (HPV) vaccine and the willingness to vaccinate HPV vaccine among college students in Xiangyang were investigated and analyzed to provide a reliable scientific basis for the primary prevention of cervical cancer prevention and control in Xiangyang. Methods By means of stratified sampling method and self-made questionnaire, this paper conducted a questionnaire survey among college students in 3 universities in Xiangyang. Results A total of 8 523 college students participated in the questionnaire survey, and 4 473 of them had sufficient knowledge of cervical cancer prevention and control and HPV vaccine, with the awareness rate of 52.48%. Male students, rural residents and non-medical majors were the influencing factors of insufficient knowledge of cervical cancer prevention and control and HPV vaccine. Among the 6 459 female college students who participated in the survey, 5,993 (92.79%) were willing to be vaccinated, and 859 (13.30%) were already vaccinated. Major, educational background, living expenses and cognitive scores were the influencing factors of HPV vaccination intention.
