Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

OBJECTIVE: To investigate the long-term outcome of laparoscope-assisted transanal total mesorectal excision (taTME) for rectal cancer. METHODS: Clinicopathological data of 29 patients with mid-low rectal cancer undergoing laparoscope-assisted taTME at Department of Gastrointestinal Surgery, the First Affiliated Hospital of Guangzhou Medical University from May 2010 to December 2015 were collected for the retrospective case-series study. All the operations were performed with transabdominal and transanal procedure simultaneously or sequentially. Perioperative presentations, pathological examinations, and oncologic outcomes were retrospectively analyzed. Long-term recurrence, metastasis and survival were assessed during follow-up. Outpatient clinic and telephone survey were used for follow-up. The follow-up time ended in December 2018. The overall survival (OS) rate and disease-free survival (DFS) rate were calculated by the Kaplan-Meier method. RESULTS: The average intra-operative blood loss was (75.9±9.5) ml (range,20 to 200). The average operating time was (223.6±4.1) minutes (range, 165 to 280). The average number of harvested lymph node was 22.3±2.0. The average length of pathological specimen was (13.1±0.6) cm. The average distal resection margin was (2.9±0.2) cm. 89.7% (26/29) of specimens was complete and 10.3% (3/29) near complete. Two cases (6.9%) had positive cutting circumferential margin. Median follow-up was 56 (range, 22 to 91) months. Local recurrence rate, distant metastasis rate, 3-year OS rate, 3-year DFS rate, 5-year OS rate, 5-year DFS rate were 10.3% (3/29), 20.7%(6/29), 96.6%, 83.2%, 87.6% and 79.6%, respectively. No incisional hernia or adhesive intestinal obstruction was found. CONCLUSION Long-term outcomes of mid-low rectal cancer patients undergoing laparoscope-assisted taTME are satisfactory.

Objective To study the application value of endoscopic thyroidectomy via total membrane dissection. Methods One hundred and sixteen patients with benign thyroid nodules were given axillo-breast approach endoscopic thyroidectomy via total membrane dissection from January 2014 to December 2016. Results Endoscopic thyroidectomy was completed in all the patients without conversion to open surgery.The operation time was 45-125 min[mean,(65.6 ±36.7)min],the blood loss was 10-220 ml[mean,(43.2 ±22.7)ml],the postoperative drainage volume was 25-305 ml[mean,(95.3 ±53.8)ml], the postoperative drainage time was 2-4 d[mean,(2.3 ±0.7)d)],and the length of hospital stay was 3-6 d[mean,(4.1 ±1.1)d].Short-term twitch occurred in 1 case and seroma occurred in 2 cases.No other complications such as hoarseness,bucking or asphyxia occurred in this series. Conclusion Endoscopic thyroidectomy via total membrane dissection can effectively avoid the injury of recurrent laryngeal nerve and parathyroid gland.

Objective To evaluate the BALB/c murine infective effects in different concentrations and different aerosol challenge times by Bordetella pertussis.Methods Four experiment groups according to different concentrations and different aerosol challenge times were designed.BALB/c murines were challenged by aerosol way.Group 1: 1010cfu/mL Bordetella pertussis challenge 15 min, group 2: 1010cfu/mL challenge 30 min, group 3: 109cfu/mL challenge 30 min, group 4: 1011cfu/mL challenge 30 min, using the normal saline challenge 30 min as control.At 0d,3d,7d,14d and 21d after challenge, the WBCs of all groups were measured and lung tissues were homogenized to calculate the bordetella pertussis clone in lung.Results After 3 days of challenge, WBCs in all groups were slightly increased.The WBCs of group 1, group 2, group 3 and group 4 were significantly increased after 7 days, with the average numbers of 8.52×109 per/L, 1.74×1010per/L, 1.15×1010per/L and 5×1010per/L, respectively.After 14 days, they were 1.77×1010per/L, 1.67×1010per/L, 1.27×1010per/L and 3.84×1010per/L respectively.WBCs in all groups were dramatically declined after 21 days.The WBC of negative control group had no obvious change during the whole process with the stable number of 3.4~7.0×109per/L.Bordetella pertussis were detected in lung of all experimental groups in each sampling point.The CFU in lung wase at peak at 7d or 14d after challenge, which was obviously decreased at 21d.Conclusion This aerosol challenge method can establish a bordetella pertussis infection mouse model successfully.

A retrospective study was conducted based on the clinical data of 42 patients of portal hypertension and splenomegaly who underwent laparoscopic splenectomy.The patients were divided into two groups including pedicle priority group and conventional group by different operative method.The operation time and intraoperative blood loss in the pedicle priority group were significantly lower than those in the conventional group (both P ＜ 0.05),and there was no statistically significant difference on the conversion rate of laparotomy,active time postoperation,exhaust time,postoperative hospitalization stay and the incidence of complications (all P ＞ 0.05).Priority processing for splenic pedicle has obvious advantages in laparoscopic splenectomy for portal hypertension and splenomegaly,and it could reduce the difficulty of operation,shorten the operation time and reduce bleeding.

Objective:To systematic review the relationships between the expression of osteopontin (OPN) and esophageal squamous cell carcinoma and its clinicopathologic feature with meta-analyses.Methods: The published studies in the PubMed, the Cochrane Library, EMbase, CBM, CNKI, VIP and WanFang databases were searched, at the time, the documents retrospective method was adopted, and then a series researches about the relationships between the expression of OPN and esophageal squamous cell carcinoma and its clinicopathologic feature were collected. The Jan., 2017 was the deadline of search. The study arranged two researcher to screen documents as the standards of inclusion and exclusion, and extract data and evaluate the quality of methodology for these included documents. The RevMan 5.2 was applied to analyze these data in this Meta analysis.Results: A total of 12 case control studies were included, which included 782 cases of esophageal squamous cell carcinoma in case group and 700 persons in control group. The results of Meta analysis showed the OR of the expression of OPN between cases group and control group was 52.71, and its 95% confidence interval (CI) was 17.95-154.79. Besides, the OR of the expression of OPN between clinical Ⅰ-Ⅱ stage group and clinical Ⅲ-Ⅳ stage group was 0.20, and its 95% (CI) was 0.07-0.60. The OR of the expression of OPN between group with lymph node metastasis and group without lymph node metastasis was 6.37, and its CI was 3.64-11.15. The OR of the expression of OPN between T1+T2 group and T3+T4 group was 0.31, and its 95% (CI) was 0.15-0.64. The differences of the expression of OPN among various group had statistically significant.Conclusion:Current evidence indicates that the expression level of OPN is significantly correlated with esophageal squamous cell carcinoma and its clinicopathologic features. Due to the limited quantity of documents and quality of included studies, above conclusions need to be verified by conducting more high quality studies.
