There were 47 kinds of main diseases and 14 kinds of dominant diseases such as fever, heartache and constipation. There were 138 acupoints, most of which were specific acupoints, mainly the spleen meridian, and the high frequency acupoints were Zusanli (ST36), Dadu (SP2), Gongsun (SP4) and so on. Clustering analysis obtained 8 kinds of acupoint combinations, which were potential prescriptions for Taibai (SP3).Conclusion:Taibai (SP3) was widely used in clinical practice in ancient times, with 8 kinds of diseases such as fever, constipation and abdominal pain as the main dominant diseases, and most of them were compatible with specific acupoints such as Zusanli (ST36), Dadu (SP2), Gongsun (SP4).

Objective:To analyze the ultrasonographic measurements of inferior vena cava (IVC) and abdominal aorta in healthy full-term neonates throughout the early postnatal period.Methods:Prospective observational study was conducted. A total of 132 healthy full-term neonates, who were born at the Kunshan First People′s Hospital between May 1 st and August 30 th, 2023, were enrolled as the study subjects. Two-dimensional and M-mode ultrasonography were used to measure the maximum and minimum diameters of the IVC and abdominal aorta in the early postnatal period. The IVC collapsibility index, the ratio of maximum IVC diameter to abdominal aorta diameter, and the ratio of minimum IVC diameter to abdominal aorta diameter were calculated. These neonates were stratified by gender, birth mode, gestational age and birth weight (<3 000 or ≥3 000 g), and independent sample t-test or Kruskal-Wallis H test was used to compare the ultrasonography measurements by different groups. Results:Among the 132 neonates, 81 were males, with a gestational age of (39.2±1.0) weeks, and a birth weight of (3 326±409) g. There were no significant statistical differences in the the maximum and minimum diameters of the IVC and abdominal aorta assessed by both two-dimensional and M-modes between the first and second days (all P>0.05). Additionally, no statistical differences were observed in the ultrasonographic measurements among neonates of different sexes, birth modes, and gestational ages (all P>0.05); but there were statistically differences between the group with birth weight of <3 000 g and the group with birth weight of ≥3 000 g (all P<0.05). There were no statistically differences in IVC collapsibility index, the ratio of the maximum diameter of IVC to the diameter of abdominal aorta, and the ratio of the minimum diameter of IVC to the diameter of abdominal aorta between the group with birth weight of <3 000 g and the group with birth weight of≥3 000 g (all P>0.05). Conclusions:The diameters of the IVC and abdominal aorta in healthy full-term neonates during the early postnatal period are correlated with birth weight. The IVC collapsibility index and the ratio of IVC diameter to abdominal aorta diameter are unrelated to birth weight and can be used to assess newborn blood volume or right cardiac preload.

Objective: To prepare a composite membrane by chitosan/β-sodium glycerophosphate(CS/β-GP) thermosensitive hydrogel combined with stromal cell derived factor-1(SDF-1) and observe its biological characteristics in vitro. Methods: Different doses of SDF-1 were added into CS/β-GP solution and then the thermosensitive gel time was measured. The SDF-1/CS/β-GP solution was membrane paved and dried to prepare composite membranes. The morphological characteristics were observed by scanning electron microscope(SEM). Composite membranes were placed into cell culture medium, and the supernatant(n=3) was extracted after standing at 6, 12, 24, 36, 48, 60 h, respectively. The concentration of SDF-1 in the solution was measured. Bone mesenchymal stem cells(BMSCs) were cultured in the Transwell room, and the composite membranes containing different concentrations of SDF-1 were placed in the lower chamber. There were four groups(n=3): Group M0 used CS/β-GP membrane(control group), Group M1, M2, M3 used SDF-1/CS/β-GP membrane(SDF-1 was 100, 200, 400 ng/mL respectively). After culture for 6, 12 and 24 h, the cells under the membrane were preserved and Giemsa stained and counted. The absorbance(OD) value was measured by MTT method to calculate the cell proliferation rate. SPSS 19.0 was used for multi-factor analysis of variance. Results : After adding a certain amount of SDF-1 into CS/β-GP solution, the gel time did not change significantly(P>0.05). The SDF-1/CS/β-GP membrane was translucent and porous at 37 ℃. In this experiment, the volumic mass of SDF-1 released by SDF-1/CS/β-GP composite membrane increased gradually with the experimental time(P<0.01). Transwell cell chemotaxis test showed that the number of BMSCs cells with directional migration increased with the prolongation of observation time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). In MTT test, the OD value of migration cell solution increased with the prolongation of time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). Conclusion The SDF-1/CS/β-GP composite membrane has a porous structure and biological activity of chemotactic BMSCs directional migration. It is a potential membrane for guided tissue regeneration.

Objective: To explore relationship between screen time and myopia in children aged 11-14 years in China. Methods: The data were extracted from "National Nutrition and Health Systematic Survey and Application for 0-18 Years Old Children". A total of 12 397 children aged 11-14 years old from 14 provinces and 28 districts/counties in seven regions of China were surveyed by using multi stage stratified random sampling method. Daily screen time and visual acuity information were collected through a questionnaire. Results: The myopia rate of 11-14 years old children in China was 45.0%, among which the rate of girls was higher than that of boys, and the rate of urban was higher than that of rural, and it increased with age ( χ 2=178.82,79.25, 495.96 , P <0.01). The daily screen time median of 12 397 children was 40.0 minutes, with boys(40.0 min) longer than girls( 35.0 min ) and urban children(40 min) longer than rural children(33.0 min) ( χ 2=20.86，102.68， P <0.01). The myopia rate of boys ( 42.5 %) with daily screen time greater than or equal to 60 minutes was higher than that of boys (36.4%) with daily screen time less than 60 minutes, and the myopia rate of girls (55.6%) with daily screen time greater than or equal to 60 minutes was higher than that of girls (48.0%)( χ 2=23.62，34.15， P <0.01). After adjusting for age, gender, region, time of medium and high intensity physical activity, intake of sugary food and sugary beverages, daily sleep time, multivariable Logistic regression model showed that girls with daily screen time greater than or equal to 60 minutes ( OR=1.14, 95%CI =1.03-1.27) had a higher risk of myopia than those with less than 60 minutes. After adjusting for confounding factors, there was no correlation between daily screen time and the degree of myopia in boys or girls( P >0.05). Conclusion Daily screen time greater than or equal to 60 minutes may be a risk factor for myopia in girls aged 11 to 14 years old. Given the complexity of the factors that affect vision, researches are needed to examine the relationship between screen time and myopia.

Objective:To explore the sex-based heterogeneity in demographic and pathological trends of lung cancer during the past 30 years.Methods:Patients with primary lung cancer who received surgical treatment in the Department of thoracic surgery, Shanghai Pulmonary Hospital Tongji University from 1989 to 2018 were retrospectively analyzed. The differences between male and female patients in age, smoking history, pathological stage and type were compared. Mann- Kendall trend test was performed for trend analysis. Results:A total of 58 433 patients were included in this study, encompassing 30 729(52.6%) men and 27 , 704(47.4%) women. Compared with male patients, female patients were younger(56.0 years old vs. 59.7 years old), and had a higher proportion of non-smokers(98.3% vs. 52.3%), stage Ⅰ lung cancers(60.6% vs. 49.3%), and adenocarcinoma(93.7% vs. 56.1%, all P-values <0.001). Trend analyses revealed that the proportion of female patients increased year by year, and surpassed males in 2015, with the current ratio of male to female being 1∶1.5. After 2013, the age of onset in females was getting younger, and the average age decreased from 58.7 years old to 54.7 years old( P=0.02). The decrease in the proportion of smoking patients was mainly reflected by male patients(from 68.5% to 31.1%, P<0.01). Stage Ⅰ lung cancers in male and females outnumbered advanced stage in 2012 and 2010, respectively, with a much higher proportion in female patients. Among male patients, adenocarcinoma has replaced squamous cell carcinoma as the most common pathological type since 2012, while in female patients adenocarcinoma remained the most common pathological type of lung cancer, and its proportion continued to increase reaching over 98%. Conclusion:A dramatic change in gender distribution was noticed during the past 30 years. Female patients became the primary population in surgically-treated lung cancers, with a trend of getting younger. The proportion of smokers and squamous cell carcinoma decreased significantly in male patients, and adenocarcinoma has become the most common pathological type of lung cancer. The proportion of stage Ⅰ lung cancers was on a dramatic rise, with the popularization of CT screening for lung cancer.

Objective:To compare the mid-term clinical efficacy of total hip replacement (THR) and closed reduction and external fixation (CREF) in treatment of intertrochanteric fractures in the elderly.Methods:A retrospective case-control study was conducted to analyze the clinical data of 155 elderly patients with unilateral intertrochanteric fractures admitted to Second Affiliated Hospital of Army Medical University from June 2011 to June 2019, including 63 males and 92 females, aged 70-98 years [(80.1±7.0)years]. According to Jensen-Evans classification, the type of fracture was type I in 2 patients, type II in 21, type III in 24, type IV in 36, type V in 67, and type R in 5. A total of 85 patients were treated by THR (THR Group) and 70 patients by CREF (CREF group). The operation time, intraoperative blood loss, blood transfusion rate, length of hospital stay, postoperative complication rate, Harris hip score at postoperative 1 year, excellent and good rate of hip joint function, and 12-item short form health survey (SF-12) physical component summary score (SF-12PCS) of postoperative quality of life, mortality rate within 1 year and survival rate were compared between the two groups.Results:The follow-up time was 1.0-9.5 years [(3.9±2.4)years]. A total of, 140 patients were followed up for more than one year, 2 patients were lost, 13 patients died within 1 year after surgery. The operation time [77(60, 100)minutes] and intraoperative blood loss [(290.6±182.3)ml] in THR group were significantly longer or more than those in CREF Group [55(50, 70)minutes, (30.5±25.0)ml] ( P<0.05). The blood transfusion rate [78%(66/85)] in THR group was significantly higher than that in CREF Group [21%(15/70)] ( P<0.05). The length of hospital stay and incidence of postoperative complications were similar between the two groups ( P>0.05). One year after operation, the Harris hip score [(84.4±15.1)points], excellent and good rate of hip joint function [76%(63/83)] and SF-12 PCS score [(16.2±1.0)points] in THR group were significantly higher than those in CREF group [(69.0±21.6)points, 43%(27/63), (14.1±2.2)points] ( P<0.05). The mortality within 1 year after operation was similar between the two groups ( P>0.05). The survival curve analysis showed that the survival status in THR group was better than that in CREF group ( P<0.05). Conclusion:Compared with CREF, THR has better joint function and quality of life, as well as a higher overall survival rate when applied to treat intertrochanteric fractures in the elderly patients.
