Objective To investigate the effects of Xiaotan Sanjie Recipe (XTSJR) on the proliferation and apoptosis of colorectal cancer cell;To study its relevant mechanism. Methods The original XTSJR aqueous solution was lyophilized, weighted, and dissolved in cell culture and stored. HCT116 cell line was treated with different concentrations of XTSJR for 72 h, and the cell proliferation was detected by CCK-8 assay. XTSJR treated HCT116 cell line with the concentration of 0.94 mg/mL and 1.88 mg/mL for 24 h, 48 h, 72 h, and the cell proliferation was detected by CCK-8 assay. HCT116 cell line was treated with different concentrations (0.24, 0.47, 0.94, 1.88 mg/mL) of XTSJR for 72 h. The cell apoptosis was detected by TUNEL assay under the fluorescence microscope, and the post-intervention expression of Caspase3 protein was detected by Western blot. Results The inhibitory effects of XTSJR on the proliferation of HCT116 cell line was concentration-time dependent. The IC50 value at 72 h-time point was 0.94 mg/mL. Medicine concentration and the treated time have interactive contribution to the inhibitory effect. XTSJR induced the cell apoptosis. The apoptosis rate increased with the increasing medicine concentration. There was statistically significant difference compared with the control group ( P<0.01). After treatment the expression of Pro-Caspase3 decreased, while the expression Cleaved Caspase3 protein increased. Conclusion XTSJR inhibits the proliferation of HCT116 cell line and induce apoptosis. Its mechanism might be related to the activity of Caspase3 protein.

Objective To study the effects of diet and physical activity factors on blood pressure in nine provinces, using the multilevel model. Methods Data was collected in the China Health and Nutrition Survey (CHNS). A total of 6706 men and 7140 women aged above 18 who attended at least one of the surveys in the year of 1997,2000,2004 and 2006 were selected, and a two-level male and female random intercept-slope growth models were applied to estimate the relationship between the intake of daily salt, vegetable, fruit, fat, protein as well as the time spent on the moderate or heavy physical activity and blood pressure. Results After controlling for age,education, BMI, drinks and total energy intake, mean of the daily salt intake per person was positively associated with systolic blood pressure in women ( β= 0.0481, s-x= 0.0178, P<0.01 ). Mean of the daily vegetable intake per person was negatively associated with systolic blood pressure in men and women, with the regression coefficients as -0.0063,-0.0068 respectively, indicating that if mean of the daily vegetable intake per person increased by 100 g, the systolic blood pressure would decrease by 0.6 mm Hg (1 mm Hg=0.133 kPa) or more. In addition, the daily vegetable intake was also negatively associated with diastolic blood pressure (P<0.01). Daily fruit intake was negatively associated with systolic blood pressure both in men and women, with regression coefficients as -0.0029 and -0.0031 respectively. Time spent on the moderate or heavy physical activity was also negatively associated with systolic blood pressure in both men and women, and diastolic blood pressure in women (P<0.05). No relationship was found between daily fat, protein intake and blood pressure. Conclusion Daily salt, vegetable, fruit intake, time spent on the moderate or heavy physical activity were associated with blood pressure in both men and women. Programs on integrated lifestyle modifications including dietary salt reduction, eating more vegetable and fruits, increasing physical activity level, plus weight control were critical for the control of high blood pressure.

OBJECTIVETo investigate the expression and the subcellular localization of HDAC9 in different brain regions of mice after cerebral ischemic injury and explore the association between HDAC9 and ischemic stroke.
METHODSTwenty-one male C57BL/6 mice were randomly divided into sham-operated group (n=9) and operated group (n=12). In the latter group, the mice with Zea-Longa neurological deficit scores of 2 or 3 following middle cerebral artery occlusion (MCAO) were assigned into MCAO group (n=9). Immunofluorescence was performed to investigate the subcellular localization of HDAC9 in the brain tissues on day 3 after MCAO. Western blotting and qRT-PCR were used to analyze the expression of HDAC9 in different regions of the brain. Results Immunofluorescence showed more intense HDAC9 expressions in the brain tissues around the infarct focus, and in the cells surrounding the infarct, HDAC9 expression was obviously increased in the cytoplasm and reduced in the cell nuclei. Compared with the other brain regions, the ipsilesional cortex with MCAO showed more abundant HDAC9 expressions at both the mRNA and protein levels (P<0.05).
CONCLUSIONHDAC9 may be closely related to cerebral ischemic injury and participate in the pathophysiological process of ischemic stroke.

BACKGROUND: Repair of tendon interface is a difficulty in orthopedics and sports medicine, and the formation of new bone is conducive to its healing. Calcitonin gene-related peptide (CGRP) plays a critical role in tissue homeostasis and repair, but its effect on the bone-tendon interface repair is unknown. OBJECTIVE: To investigate the effect of CGRP on the expression of osteocalcin and to evaluate the effect of CGRP on the early healing of rotator cuff injury in a mouse model. METHODS: A mouse model of supraspinatus insertion-humerus injury was created. All model mice were then randomized into two groups, and given the injection of 5 nmol/kg CGRP (experimental group) or same volume of normal saline (control group) through the glenohumeral joint immediately after operation, thrice weekly, for 2 weeks. The mice were sacrificed at postoperative 4 and 6 weeks to remove the rotator cuff samples for hematoxylin-eosin staining and biomechanical test. The mRNA and protein expression levels of osteocalcin were surveyed by qRT-PCR, immunohistochemistry, and western blot assay. RESULTS AND CONCLUSION: At postoperative 4 and 6 weeks, the mRNA and protein expression of osteocalcin in the experimental group were significantly higher than those in the control group (P < 0.05). Compared with the control group, there were more fibrocartilages in the experimental group at 4 weeks postoperatively, and more new bone formation in the experimental group at 6 weeks postoperatively. At 4 weeks postoperatively, failure load in the experimental group increased slightly, but it was not significantly different from that in the control group (P > 0.05); at 6 weeks postoperatively, failure load in the experimental group was significantly higher than that in the control group (P<0.05). To conclude, local injection of CGRP can up-regulate the expression of osteocalcin and the formation of new bone at the injury site, which can enhance early healing the injured rotator cuff.

Objective:
Surgical procedures for patients with posttraumatic syringomyelia (PTS) remain controversial. Until now, there have been no effective quantitative evaluation methods to assist in selecting appropriate surgical plans before surgery.
Methods:
We consecutively enrolled PTS patients (arachnoid lysis group, n = 42; shunting group, n = 14) from 2003 to 2023. Additionally, 19 intrathecal anesthesia patients were included in the control group. All patients with PTS underwent physical and neurological examinations and spinal magnetic resonance imaging preoperatively, 3–12 months postoperatively and during the last follow-up. Preoperative lumbar puncture was performed and blood-spinal cord barrier disruption was detected by quotient of albumin (Qalb, cerebrospinal fluid/serum).
Results:
The ages (p = 0.324) and sex (p = 0.065) of the PTS and control groups did not differ significantly. There were also no significant differences in age (p = 0.216), routine blood data and prognosis (p = 0.399) between the arachnoid lysis and shunting groups. But the QAlb level of PTS patients was significantly higher than that of the control group (p < 0.001), and the shunting group had a significantly higher QAlb (p < 0.001) than the arachnoid lysis group. A high preoperative QAlb (odds ratio, 1.091; 95% confidence interval, 1.004–1.187; p = 0.041) was identified as the predictive factor for the shunting procedure, with the receiver operating characteristic curve showing 100% specificity and 80.95% sensitivity for patients with a QAlb > 12.67.
Conclusion
Preoperative QAlb is a significant predictive factor for the types of surgery. For PTS patients with a QAlb > 12.67, shunting represents the final recourse, necessitating the exploration and development of novel treatments for these patients.
