Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective To analyze the correlation between the prevalence of chronic non-communicable diseases (NCDs) and fall incidence among the elderly in urban and rural areas in Chongqing, and to provide evidence for targeted intervention. Methods In 2019, a questionnaire survey was conducted among the elderly aged 65 and over in four districts and counties using multistage stratified cluster random sampling. The difference of NCDs prevalence and fall incidence was compared by Chi-square test. The correlation between NCDs and fall incidence was analyzed by multivariate logistic regression. Results A total of 806 and 801 elderly people aged 65 and above in urban and rural areas，respectively, were investigated The fall incidence among the elderly in rural areas (12.98%) was higher than that in urban areas (7.94%) (χ2=10.916, P=0.001). The multivariable logistic regression analysis showed that the prevalence of heart disease (OR=2.988, 95%CI:1.544-5.785), osteoporosis (OR=2.696, 95%CI:1.527-4.760) and vestibular dysfunction or deafness (OR=3.180, 95%CI:1.142-8.861) was associated with fall incidence among urban elderly people. Factors including need for care (OR=2.315，95%CI：1.130-4.744), diabetes (OR=3.067，95%CI:1.634-5.756), osteoporosis (OR=1.972, 95%CI:1.210-3.214), and arthritis (OR=2.975, 95%CI:1.901-4.657) were associated with fall incidence among rural elderly people. Conclusion The fall incidence among the elderly in rural areas is higher than that in urban areas in Chongqing. The prevalence of NCD is high among the elderly. Timely treatment of NCDs should be provided to reduce fall incidence among the elderly.

OBJECTIVE To establish the estimation model for the exposure of mycophenolic acid （MPA） in early renal transplant recipients [calculated by the area under the plasma concentration-time curve with 12 h （AUC0－12 h）]. METHODS Twenty kidney transplant recipients， who received triple immunosuppressive therapy of mycophenolate mofetil （MMF）+tacrolimus+ methylprednisolone， were selected and given MMF dispersible tablets （750 mg， q12 h） on the 15th day after the operation； the blood samples were collected from the patients before and 0.5， 1.0， 1.5， 2.0， 3.0， 4.0， 6.0， 8.0， 12.0 hours after the administration， respectively. The blood concentration of MPA was determined， and the pharmacokinetic parameters of MPA were calculated. The multivariate linear stepwise regression analysis method was used to fit an estimation formula for the finite sampling method suitable for MPA-AUC0－12 h of the recipients. Bland-Altman analysis was used to evaluate the agreement between the estimation formula and the classical pharmacokinetic method. RESULTS The main pharmacokinetic parameters of MPA in 20 renal transplant recipients： c0 was （1.53±0.84） μg/mL， cmax was （12.07±5.97） μg/mL， t1/2 was （5.41±3.67） h， tmax was （1.58±0.75） h， and the average AUC0－12 h calculated by the classical pharmacokinetic method was （33.95±13.40） μg·h/mL. MPA-AUC0－12 h was estimated with sampling points of “4.0， 8.0， 12.0 h”； the simplified calculation formula was AUC0－12 h＝12.058+2.819c4.0+7.045c8.0+ 3.879c12.0 （R 2＝0.934）. The predicted value had a good correlation and consistency with the measured value， and 95.0% of predicted values did not exceed the x±1.96SD （standard deviation） range. CONCLUSIONS The estimation model is established successfully for the exposure of MPA in early renal transplant recipients； the model has better prediction accuracy and fewer sampling points.

OBJECTIVE To explore and establish an analysis method for sulfamethoxazole blood concentration in patients with heart transplantation to guide clinical rational drug use. METHODS A new two-dimensional liquid chromatograph (2D-LC-UV) based on column switching technology was used. The on-line solid-phase extraction of sulfamethoxazole in serum was performed using a one-dimensional column Aston SC2(3.5 mm×25 mm, 5 μm), then it was intercepted and retained through the middle column Aston SBR(3.5 mm×10 mm, 5 μm), and the target analytes were completely separated and detected by transfer to the second-dimension column Aston SNX4(4.6 mm×130 mm, 5 μm). The chromatographic conditions were obtained by optimization. The one-dimensional mobile phase was acetonitrile-methanol-H2O(10:10:70), the flow rate was 0.8 mL·min-1; the two-dimensional mobile phase ratio was BPI-1 basic mobile phase-API-3 acidic mobile phase-methanol(20:40:40) the flow rate was 1.2 mL·min-1. The UV detection wavelength was 240 nm. RESULTS The correlation coefficient between the concentration of sulfamethoxazole and peak area was in the range of 9.96‒200.04 μg·mL-1 with R2=0.999 6, it showed a good linear relationship. The intra-day and inter-day precisions(RSD) at low, medium and high concentrations were <15%, and the relative recoveries were between 85%‒115%. The blood concentration of 56 patients in the hospital was measured, and only 30 patients(53.57%) had the blood sample sulfamethoxazole concentration of 100‒150 μg·mL-1, and the rest were not comfortable about the concentration treatment window; there were 0 cases of grade III-IV adverse reactions in the urinary system/blood system/liver, etc. CONCLUSION This method has a simple pre-treatment, high automation, can be sampled in large volumes, and has high accuracy and sensitivity. It can meet the requirements of clinical applications. The research results can provide a methodological reference for clinical therapeutic drug monitoring..

Objective To investigate the current situation of animal injury among children in Chongqing, and to provide a scientific basis for relevant departments to formulate and implement strategies and measures to prevent and control animal injury to children. Methods According to the method of multi-stage stratified cluster sampling, 14,056 children in grades 4-12 in four districts of Chongqing were selected as the investigation subjects, and the occurrence of animal injuries in the past 6 months was investigated. Results The incidence of animal injury among school children in Chongqing was 0.35% and the incidence of person-time was 0.36%. The incidence rate in males (0.48%) was higher than that in females (0.31%). The incidence rate in urban children (0.43%) was higher than that in rural children (0.30%). The incidence of animal injury was the lowest in nuclear families (0.25%), and the highest in single-parent families (0.82%). There were statistically significant differences in the incidence of animal injuries in children among different fathers' occupational types, family types and parents' parenting styles (P<0.05).  The main place of child animal injury was home (57.14%). Recreational activities were the main cause of animal injury (51.02%). The main injuries were lower limbs (42.86%), upper limbs (24.49%) and head (10.20%). Conclusion The prevention and control of children's animal injury in Chongqing should focus on boys and families. It is suggested to take targeted and comprehensive interventions to prevent animal injuries in children.

Objective: PS128 is a novel psycho biotic strain, it has been reported to play an important role in neuropsychiatric disorders. This study investigated the clinical effect of PS128 supplementation on patients with anxiety. Methods: A total of 200 patients with anxiety were recruited, and divided into two groups (n = 100/group). The control group received oral treatment with citalopram, and the PS128 group received PS128 capsules based on citalopram treatment. Hamilton Anxiety Scale (HAMA) and Self-Rating Anxiety Scale (SAS) were used to evaluate the anxiety levels.After 2 months of continuous administration, clinical efficacy was evaluated according to HAMA score. Results: There was no significant difference in HAMA and SAS scores between the two groups before treatment. With the treatment prolonged, the HAMA and SAS score decreased gradually in both control and PS128 groups, and the decrease rate of PS128 group was significantly greater than that of the control group. The clinical effective rates of PS128 group were higher than those in the control group, high levels of clinical cure rate were also detected in the PS128 group. Compared with the control group (22%), the incidence of adverse reactions was significantly reduced for patients in the PS128 group (4%). Conclusion The treatment effect of citalopram combined with PS128 against anxiety is satisfactory clinically. It can greatly improve the anxiety symptoms of patients, increase the cure rate, reduce adverse reactions.
