Through a compound induction method, combined with neurobehavioral, macroscopic characterization and objective pathological evaluation indicators, a murine depression model of liver depression transforming into fire syndrome was constructed and confirmed. The model was constructed using a combination of sleep deprivation, light exposure, and alternate-day food deprivation. Evaluation was conducted at three levels: face validity, constructs validity, and predictive validity. The establishment of the liver depression transforming into fire syndrome depression model was further validated through the counterproof of traditional Chinese medicine formulas. In terms of face validity, compared to the control group, mice in the model group exhibited typical depressive symptoms in neurobehavioral assessments; the general observation of the model group mice reveals disheveled and lackluster fur, along with delayed and easily agitated responses. Additionally, there is a substantial increase in water consumption. In the sleep phase detection of mouse, the model group showed a significant increase in the proportion of time spent in the wake phase during sleep, accompanied by a significant decrease in the proportions of time spent in both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep phases. There are significant differences in physiological indicators such as average blood flow velocity, blood flow rate, tongue, urine, and claw color (r values) in the internal carotid artery. Structural validity demonstrated that levels of 5-hydroxytryptamine (5-HT), dopamine (DA), and γ-aminobutyric acid (GABA) in the hippocampus of model mice decreased significantly, while acetylcholine (ACh), tryptophan (Try), and glutamic acid (Glu) levels increased significantly. Treatment with Danzhi Xiaoyao San led to varying degrees of restoration in the aforementioned neurotransmitters. In terms of predictive validity, the antidepressant paroxetine effectively ameliorated depressive behaviors in the model mice, and the classic formula Danzhi Xiaoyao San demonstrated varying degrees of improvement in depression-related indicators. In conclusion, this study has established a novel animal model of liver-stagnation with the fire depression, thereby expanding the repertoire of traditional Chinese medicine depression models. This development contributes to the diversification of melancholic syndrome models in Chinese medicine, offering a broader spectrum of options for scientific exploration, efficacy evaluation, and drug screening in the future prevention and treatment of depression with traditional Chinese medicine. Animal experiments were conducted with the approval and supervision of the Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine (ethics number: 20230313040).

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

The pursuit of cosmetic effects in post-surgical wounds has led to the development of ultra-minimally invasive techniques in surgery. Minimal invasive surgery has replaced open surgery and has become the new gold-standard for treating diseases. One such technique is the single incision triangulated umbilicus surgery (SITUS), which offers several advantages over traditional laparoscopic and other scarless surgeries, including reduced trauma, faster recovery, and better cosmetic outcomes. SITUS also has a short learning curve, aligns with conventional instrumentation operating habits, and can be used for whole abdominal surgeries. Chinese scholars have made further improvements to the SITUS technology, including expanding its applicability in intra-abdominal surgery and refining its incision closure methods to achieve superior cosmetic results. Currently, SITUS technology is experiencing rapid development in urology applications and has demonstrated satisfactory results in both domestic and international reports. This review aims to discuss the effectiveness and development of the SITUS technique in urology.

As an important model animal, fruit fly is characterized by outstanding genetic characteristics, relatively perfect nervous system, rapid reproduction, and low cost. Thus, it has been applied in the research on neuropsychiatric disorders in recent years, showing great potential in life science. The incidence of neuropsychiatric disorders has been on the rise, and the disorders have high disability rate and low case fatality rate. The global drug demand for such diseases is second only to cardiovascular and cerebrovascular diseases. At the moment, the demand of the drugs for the diseases have been rising, and it is an urgent task to develop related drugs. However, the research and development of the drugs are time-intensive and have a high failure rate. A suitable animal model can help shorten the time for drug screening and development, thereby reducing the cost and failure rate. This study reviews the application of fruit flies in several common neuropsychiatric disorders, which is expected to provide new ideas for the research and application of the model animals in traditional Chinese medicine.

Aim To explore the roles of miRNA-132 and its related proteins(Mecp2, CREB)in the mechanism of methamphetamine(MA)-induced neurotoxicity and dependence.Methods The rats were intraperitioneally injected(ip)with MA(10 mg·kg-1·d-1)to establish methamphetamine dependence model with different dependent time courses of 1 week, 2 weeks, and 4 weeks respectively.The miRNA-132 and Mecp2 mRNA were detected by RT-qPCR, and the Mecp2, p-Mecp2, CREB and p-CREB proteins were detected by Western blot in the tissues of frontal cortex and hippocampus.Results In the frontal cortex, the miRNA-132 and Mecp2 mRNA were up-regulated in MA-dependent groups(P<0.05 and P<0.01), while the Mecp2 protein were down-regulated(P<0.01).MA could promote the phosphorylation of Mecp2 protein in the frontal cortex(P<0.01).In hippocampus, the miRNA-132 was down-regulated in the MA-dependent groups, but Mecp2 mRNA was up-regulated(P<0.05).Mecp2 protein increased in MA-dependent 1 week group(P<0.05), and then recovered with the prolonged time of MA dependence, then decreased in MA-dependent 4 weeks groups(P<0.05)in hippocampus.The phosphorylation level of Mecp2 was significantly decreased in the 1 week group(P<0.01), and then increased in the 2 weeks group(P<0.01)in hippocampus.Conclusions MA could induce an abnormal expression of miRNA-132 in the frontal cortex and hippocampus, and miRNA-132 might inhibit the translation of Mecp2 mRNA and induce the decrease expression of Mecp2 protein in the frontal cortex.But in hippocampus, miRNA-132 does not show the correlation with the Mecp2 expression trend of the frontal cortex.And miRNA-132 regulation does not depend on the expression of Mecp2 in hippocampus.

Objective To evaluate the effectiveness of the integrated schistosomiasis control measures in Changzhou City from 2015 to 2020, so as to provide insights into the formulation of the strategy used to consolidate the schistosomiasis elimination achievements. Methods The annual schistosomiasis control working report and integrated schistosomiasis control data were collected in Changzhou City from 2015 to 2020, and the prevalence of Schistosoma japonicum infections in humans and livestock and snail status were analyzed to evaluate the effectiveness of the integrated schistosomiasis control measures. Results During the period from 2015 to 2020, a total of 112 061 person-time individuals received serological tests for S. japonicum infections in Changzhou City, and the sero-prevalence was 0.15% to 1.09% during the 6-year period, with a significant difference seen among years (χ² = 288.11, P < 0.05). From 2015 to 2020, a total of 13 435 person-time individuals received stool examinations, with no egg-positives identified; among 5 840 herd-time livestock receiving schistosomiasis examinations, no positives were detected, while a 100% coverage of fencing livestock was seen each year. During the 6-year period, a total of 38.40 hm² snail habitats were found, including 8.97 hm² emerging snail habitats, and among the 2 344 snails dissected, no S. japonicum infection was found. Chemical treatment covered an area of 385.71 hm², and environmental improvements covered an area of 200.39 hm². The mean density of living snails was less than 0.1 snails/0.1 m² in snail habitats found in Changzhou City each year from 2015 to 2020, and the coverage of harmless toilets was 100% in 2020. During the 6-year period, a total of 3.740 6 million person-time individuals were given schistosomiasis health education in Changzhou City. Conclusions Changzhou City is now at the post-elimination surveillance stage; however, there are still factors affecting schistosomiasis transmission. The schistosomiasis surveillance system remains to be improved to consolidate the schistosomiasis elimination achievements in Changzhou City.

OBJECTIVE: To investigate the short-term clinical effect of the cervical anterior Hybrid surgery in the treatment of two-segment and three-segment cervical spondylosis. METHODS: From January 2018 to January 2019, 108 patients who were performed anterior Hybrid surgery with cervical degenerative diseases were collected. The patients were divided into a two-segment group with 52 patients and a three-segment group with 56 patients according to surgical segments. In two-segment group, there were 24 males and 28 females, aged from 35 to 67 years old with an average of(45.94±14.67) years old. In three-segment group, there were 23 males and 33 females, aged from 32 to 65 years old with an average of (47.54±15.34) years old. The outcome indicators of the two groups were compared. Clinical indicators:neck disability index(NDI) was used to evaluate daily life ability, Japanese Orthopedic Association(JOA) score was used to evaluate neurological function improvement, visual analogue scale(VAS) was used to evaluate pain intensity, and general clinical results were graded according to Odom's score. Cervical range of motion (ROM), fusion and complications were measured by X-ray, CT and MRI. RESULTS: All operations were successfully completed and all patients were followed up for more than 12 months. The operation time of two-segment group and three-segment group were 95 to 180 min with an average of(152.30±44.74) min and 110 to 210 min with an average of (165.18±45.86) mins, the blood loss were 20 to 100 ml with an average of (32.88±8.75) ml and 20 to 150 ml with an average of(34.64±10.63) ml respectively which has no statistical differences between the two groups (P>0.05). Compared with those before surgery, NDI, JOA, VAS and Odom's scores between two groups were significantly improved at 12 months after operation(P<0.05). However, there was no significant difference in the NDI, JOA and Odom's scores between two groups (P>0.05), and VAS in three-segment group was higher than that in two-segment group. There was no significant difference in C₃-C₇ cervical mobility between two groups. Surgical incisions healed smoothly in all patients without complication such as spinal cord injury and cerebrospinal fluid leakage. The bone fusion of the two groups were 43 cases (82.69%) and 45 cases(80.35%) respectively. In two-segment group, there were 2 cases of adjacent segmental hyperosteogeny, and there were 3 cases of adjacent segmental hyperosteogeny and 1 case of adjacent posterior longitudinal ligament ossification in the three-segment group. In addition, in three-segment group, there was 1 case of looseness of implants with no obvious clinical symptoms. CONCLUSION The anterior Hybrid surgery in treating multi-level cervical spondylosis could not only improve clinical symptoms of patients but also preserve mobility. Meanwhile, the efficacy and safety of Hybrid surgery in different multi-level cervical disc diseases are confirmed, proving its value in clinical practice.

Hypoxemia is a common complication of pneumonia, asthma, and bronchopulmonary dysplasia in children.Rapid identification of hypoxemia is of great significance for the disposal and management of critical children.Pulse oximetry is recognized by the World Health Organization as the best way to monitor hypoxemia in children, and it can monitor pulse oxygen saturation noninvasively and continuously.Based on the related literature at home and abroad, combined with the clinical needs of pediatrics, the " Expert consensus on clinical application of pulse oximetry in children" is formulated to improve the understanding of pediatricians and nurses on the application in pediatric clinical practice, principle, operation techniques, and limitations of pulse oximetry.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

OBJECTIVE: To investigate the clinical effect of anterior cervical Hybrid surgery in the treatment of cervical degenerative diseases (CDD) and observe the incidence of heterotopic ossification of disc replacement segment at 1 year after surgery. METHODS: From January 2015 to April 2018, 35 patients who received anterior cervical hybrid surgery met the inclusion and exclusion criteria and the complete clinical follow up data were analyzed retrospectively. Complete imaging follow-up data were obtained from 24 patients. There were 15 males and 20 females, aged from 39 to 70(55.57±7.73) years old. The amount of bleeding was for 20 to 100 (40.29±18.39) ml, and the hospitalstay was for 4 to 28(11.03±4.63) days, and the follow-up time was(12.97±1.36) months. Clinical outcomes were assessed by the Tanaka Yasushi cervical spondylitis symptom scale 20 score (YT20), and Japanese Orthopaedic Association (JOA) score. The occurrence of heterotopic ossification after Hybrid surgery was evaluated by X-ray according to McAfee standard one year after operation. Patients with or without heterotopic ossificationwere divided into two groups and their clinical effects were compared. RESULTS: At the final follow up, the mean YT20 score and JOA score were significantly higher than those before operation (P <0.05), and the average improvement rate of JOA was (70.66 ±0.44)%. One year after operation, the heterotopic ossification occurred in 10 of 24 segments, with incidence of 41.70%(10/24), including 29.20% in gradeⅠand 12.50% in gradeⅡ. The results of clinical efficacy comparison between patients with and without heterotopic ossification were as follows:there was no significant difference in JOA score before and after operation ( CONCLUSION The short-term clinical effect of Hybrid surgery is satisfactory for cervical degenerative diseases, and the cause of heterotopic ossification still needs tobe further explored.
