ObjectiveTo explore the mechanism of Shenmai injection in improving cisplatin resistance in non-small cell lung cancer (NSCLC) based on the endoplasmic reticulum stress through protein kinase R-like endoplasmic reticulum kinase (PERK)/activated transcription factor 4 (ATF4)/C/EBP homologous protein (CHOP) signaling pathway. MethodsBALB/c nude mice bearing cisplatin-resistant human lung cancer cell line (A549/cisplatin) were randomly divided into four groups: Blank control group (0.9% sodium chloride), cisplatin group (5 µg·g-1cisplatin), Shenmai injection group (5.2 mg·g-1 Shenmai injection), and combination therapy group (5.2 mg·g-1 Shenmai injection +5 µg·g-1cisplatin). The drug intervention lasted for 4 weeks, and the changes in body weight and tumor volume were monitored. Hematoxylin-eosin (HE) staining was performed to observe tumor tissue pathology. Transmission electron microscopy (TEM) was used to assess the morphology of the endoplasmic reticulum. Immunohistochemical assay was conducted to measure the positive expressions of PERK, ATF4, and CHOP in tumor tissues. Western blot quantified the protein expression of immunoglobulin heavy chain binding protein (BIP), PERK, phosphorylated PERK (p-PERK), eukaryotic translation initiation factor 2α (eIF2α), phosphorylated eIF2α (p-eIF2α), ATF4, CHOP, B-cell lymphoma -2 (Bcl-2), and Bcl-2 Associated X protein (Bax). A549/cis cells were divided into blank group: Blank control group (normal culture medium), cisplatin group (23.3 µmol·L-1 cisplatin), Shenmai Injection group (20 g·L-1 Shenmai injection), and combination therapy group (20 g·L-1 Shenmai injection+23.3 µmol·L-1 cisplatin). Cell counting kit-8 (CCK-8) method was used to detect cell viability, TEM was used to observe the morphology of endoplasmic reticulum, and Western blot was used to detect endoplasmic reticulum stress and apoptosis-related proteins. ResultsCompared with the cisplatin group, the combination therapy group showed increased body weight (P<0.05), decreased tumor volume (P<0.05), and expanded endoplasmic reticulum in tumor cells. The positive expressions of PERK, ATF4, and CHOP increased (P<0.05). Western blot revealed elevated protein expression levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, ATF4, CHOP, and Bax (P<0.05), while Bcl-2 expression decreased (P<0.05). As shown in the in vitro experiment, compared with the cisplatin group, the combination therapy group exhibited a reduced cell survival rate (P<0.05). TEM revealed increased endoplasmic reticulum dilation and vesicular degeneration. Western blotting showed increased protein levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, ATF4, CHOP and Bax (P<0.05), with decreased Bcl-2 expression (P<0.05). ConclusionShenmai injection combined with cisplatin has a synergistic antitumor effect in NSCLC, which may be attributed to the activation of endoplasmic reticulum stress response mediated by the PERK/eIF2α/ATF4/CHOP signaling pathway and the induction of tumor cell apoptosis.

OBJECTIVE:
To investigate the current status of long-term quality of life in patients with severe acute pancreatitis (SAP) who have been cured and discharged, and to analyze the influencing factors affecting long-term quality of life in SAP cured patients after discharge.
METHODS:
A retrospective collection was conducted. Patients who were received standardized treatment before being cured and discharged from the hospital admitted to the first department of critical care medcine of the Second Affiliated Hospital of Anhui Medical University from January 2017 to December 2023 were enrolled. According to the 36-item short form health survey scale (SF-36) score, patients were divided into high score group (high quality of life, the top 50% of patients with total SF-36 score) and low score group (low quality of life, the bottom 50% of patients with total SF-36 score). The gender, age, history of hypertension and diabetes, etiology of pancreatitis, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), CT severity index (CTSI), laboratory indicators such as C-reactive protein (CRP), procalcitonin (PCT), blood glucose, and triglycerides upon admission, use of vasoactive drugs, non-invasive/high-flow ventilation, invasive ventilation, retroperitoneal puncture and drainage, open pancreatic surgery treatment and secondary infection during hospitalization were collected, as well as the retention of abdominal drainage tubes at discharge from hospital. Distribute follow-up questionnaires or telephone follow-up surveys through WeChat and Question Star programs to investigate the pancreatic secretion function, chronic abdominal pain, and recurrence of pancreatitis of patients after discharge. Multivariable Logistic regression was used to analyze the relevant factors affecting the long-term quality of life of cured patients with SAP.
RESULTS:
A total of 86 patients were ultimately enrolled. There were 43 patients in both the high and low score groups. Among 86 patients, 20 experienced acute pancreatitis recurrence, with a recurrence rate of 23.26%. Twenty-two (25.58%) experienced chronic abdominal pain after discharge, and 5 patients (5.81%) needed medication to relieve pain. Thirty-three patients (38.37%) had pancreatic exocrine dysfunction after discharge, characterized by abdominal distension, constipation or diarrhea. Twenty-two patients (25.58%) suffered from pancreatic endocrine dysfunction, and were diagnosed with diabetes. Univariate analysis showed that compared with the high score group, the low score group had more patients with hypertension, initial renal dysfunction, initial severe metabolic acidosis, initial serum calcium < 2.0 mmol/L, blood glucose > 11.1 mmol/L and cultured Gram positive bacteria (from blood/body fluid/pancreatic necrotic tissue) during treatment (48.84% vs. 16.28%, 60.47% vs. 32.56%, 18.60% vs. 4.65%, 88.37% vs. 62.79%, 55.81% vs. 30.23%, 34.88% vs. 13.95%), had higher CTSI score (6.60±1.61 vs. 5.77±1.32), lower hemoglobin level at discharge (g/L: 102.30±18.78 vs. 110.72±16.68), and a lower proportion of etiological interventions after discharge (34.88% vs. 67.44%), the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that hypertension [odds ratio (OR) = 4.814, 95% confidence interval (95%CI) was 1.196-19.378], initial serum calcium < 2.0 mmol/L (OR = 6.688, 95%CI was 1.321-33.873) and initial blood glucose > 11.1 mmol/L (OR = 6.473, 95%CI was 1.399-29.950) were risk factors for long-term quality of life in cured SAP patients (all P < 0.05), while post discharge prophylactic intervention was a protective factor for long-term quality of life (OR = 0.092, 95%CI was 0.020-0.425, P < 0.01).
CONCLUSIONS
Cured SAP patients have varying degrees of impaired secretion function and the possibility of recurrence of acute pancreatitis. Hypertension, initial serum calcium < 2.0 mmol/L and blood glucose > 11.1 mmol/L are independent influencing factors for low long-term quality of life in cured SAP patients. Prevention and intervention targeting the etiology of pancreatitis after discharge can improve the long-term quality of life of cured SAP patients.

Objective To evaluate the value of imaging quantification parameters in artificial intelligence (AI) assisted diagnosis systems in clinical decision-making for lung nodules≤2 cm and the diagnostic efficacy of AI. Methods Lung nodule patients admitted to Affiliated Zhongshan Hospital of Dalian University from 2020 to 2023 were included. Imaging parameters of lung nodules were extracted using AI assisted diagnosis systems. Multifactor analysis was used to screen predictors for distinguishing benign and malignant nodules and high-risk predictors for recurrent invasive adenocarcinoma, and a diagnostic model was established and its performance evaluated. The diagnostic efficacy of the AI system was judged according to pathological results. Results A total of 594 patients with lung nodules were included, including 202 males and 392 females, with an average age of (58.75±11.55) years. Volume, average CT value, and 3D maximum diameter of non-solid nodules were independent predictors of malignant nodules, with thresholds of 287.4 mm3, −491 HU, and 12.0 mm, respectively. The area under the curve (AUC) for diagnostic efficacy was ranked from high to low as combined model (0.802), volume (0.783), average CT value (0.749), and 3D maximum diameter (0.714). The average CT value and 3D long diameter of solid nodules were independent predictors of malignant nodules, with thresholds of −81 HU and 17.5 mm, respectively, and AUC values of 0.874 and 0.686, respectively, with the combined prediction AUC of 0.957. The mass of cystic nodules was an independent predictor of malignancy when the mass>180.7 mg. Independent predictors of high recurrence risk of invasive adenocarcinoma in non-solid nodules were consolidation-tumor ratio (CTR), average CT value, 3D long diameter, and volume, with thresholds of 0.14, −386 HU, 15.6 mm, and 1018.9 mm3, respectively, and diagnostic efficacy was ranked from high to low as combined model (0.788), 3D long diameter (0.735), volume (0.725), average CT value (0.720), and CTR (0.697). The accuracy of AI in predicting benign and malignant target nodules was 87.4%, with positive predictive value of 96.6% and negative predictive value of 58.9%. Conclusion In clinical decision-making for lung nodules ≤2 cm, AI assisted diagnosis systems have high application value.

BackgroundPostpartum depression (PPD) is a prevalent postpartum complications that significantly compromises women's psychological and physical well-being. Repetitive transcranial magnetic stimulation (rTMS), a conventional neuromodulation technique, has been increasingly used in the treatment of PPD. However, high-quality evidence regarding its efficacy and safety remains limited. ObjectiveTo evaluate the efficacy and safety of rTMS in the treatment of PPD, thereby providing references for clinical treatment. MethodsDatabases including Cochrane Library, PubMed, Embase, CNKI, Wanfang, VIP and China Biology Medicine disc (CBM) were electronically searched for randomized controlled trials (RCTs) on rTMS for PPD, with the search spanning from database inception to February 8, 2025. Study quality was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1, and the certainty of evidence was graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Meta-analysis was conducted using RevMan 5.3 and Stata 12.0. The outcomes of the Meta-analysis included the total effective rate, Edinburgh Postnatal Depression Scale (EPDS) score, Hamilton Depression Rating Scale (HAMD) score, and adverse reactions (dizziness, headache, nausea, diarrhea, and the overall incidence of adverse reactions). ResultsA total of 11 studies involving 729 patients with PPD were included. Meta-analysis results showed that the total effective rate in the study group was significantly higher than that in the control group (OR=5.54, 95% CI: 3.07–10.01, P<0.01). Both EPDS score (SMD=-2.38, 95% CI: -3.39–-1.37, P<0.01) and HAMD score (SMD=2.53, 95% CI: 1.21–3.85, P<0.01) in the study group were significantly lower than those in the control group, with statistically significant differences. Comparisons between the study group and control group reveal no significant differences in the incidence of dizziness and headache (RR=1.47, 95% CI: 0.63–3.43, P>0.05), nausea (RR=1.46, 95% CI: 0.55–3.86, P>0.05), diarrhea (RR=0.71, 95% CI: 0.23–2.20, P>0.05), and overall adverse reactions (RR=1.30, 95% CI: 0.79–2.15, P>0.05). GRADE assessment rated the four indicators of dizziness and headache, diarrhea, overall incidence of adverse reactions, and EPDS score as "moderate-certainty evidence", and rated the total effective rate, nausea, and the HAMD score as "low-certainty evidence". ConclusionrTMS demonstrates certain therapeutic efficacy for PPD, with a safety profile comparable to conventional treatment.

Chinese Journal of School Health 2024;45(2):277-282
Objective:
To evaluate the performance of four simplified screening methods of elevated blood pressure commonly used among children and adolescents according to Chinese guidelines for prevention and treatment of hypertension (revised in 2018), so as to provide a reference for the early detection of the elevated blood pressure among children and adolescents.
Methods:
Stratified cluster random sampling method was used to monitor the physical fitness of 5 211 children and adolescents in a city of Shanxi Province from October to November 2021. Chinese guidelines for prevention and treatment of hypertension was considered as gold standard, and sensitivity, specificity, area under the curve (AUC) and Kappa value were calculated to evaluate the screening effectiveness of formula method, height specific method, age group specific method, sex and age specific method for screening elevated blood pressure.
Results:
The detection rates of elevated blood pressure among children and adolescents screened by gold standard, formula method, height specific method,age group specific method, sex and age specific method were 21.9%, 24.0%, 21.1%, 24.5% and 20.2%, respectively. There was no significant difference between prevalence of elevated blood pressure screened by formula method, sex and age specific method and gold standard( χ 2=1.21, 1.41, P >0.05), whereas height specific method and age group specific method had significant differences with gold standard ( χ 2=20.39, 67.09, P <0.05). AUC was the largest for height specific method [0.94(95% CI =0.93-0.95)], and the smallest for age group specific method [0.87(95% CI = 0.86 -0.88)]. The Kappa values of height specific method (0.89) and sex and age specific method (0.89) were both greater than 0.85 , which were more consistent with the screening effectiveness of gold standard. When comparing by sex, age and body mass index (BMI), the screening effectivenesses were consistent with the overall in boys, 6-11 years and normal body weight groups, while the screening effectivenesses were different in girls, 12-17 years, overweight and obese groups. The AUC (0.87), Kappa value (0.71) and sensitivity (82.33%) of age group specific method were the lowest and the screening effectiveness was the worst.
Conclusion
Height specific method is more effective and can be used for early identification and self detection of blood pressure abnormalities among children and adolescents.

ObjectiveTo observe the clinical effect of Jieyu Qingxin formula granules combined with remote interactive cognitive behavioral therapy for insomnia (CBT-I) on chronic insomnia of liver depression and fire-turning type. MethodThis study was a prospective randomized controlled trial. 120 patients with chronic insomnia of liver depression and fire-turning type in Lu'an traditional Chinese medicine Hospital from January 2022 to June 2023 were selected as objects. They were randomly divided into two groups,with 60 cases in each group. The control group received remote interactive CBT-I. The observation group was treated with Jieyu Qingxin formula granules on the basis of the control group. Intervention treatment lasted for four weeks,and observation lasted for six weeks. Comparison of data of each group:clinical efficacy,changes in traditional Chinese medicine (TCM) syndrome score before and after treatment,changes in insomnia severity index (ISI) score,self-rating depression scale (SDS) and self-rating anxiety scale (SAS) score changes,total sleep time,wake time,sleep latency,sleep efficiency, Actigraphy sleep parameter value changes,serum neuron specific enolase (NSE) ,adenosine,dopamine (DA), 5-hydroxytryptamine (5-HT) level changes,and adverse reactions. ResultThe total effective rate in the observation group (92.45%,49/53) was higher than that in the control group(76.92%,40/52), and the difference was statistically significant(χ2=4.711 1,P<0.05). After treatment,TCM syndrome score,ISI score,SAS score, and SDS score were decreased in all groups. The total sleep time was extended,and wake time and sleep latency were shortened. The sleep efficiency was increased,but the NSE and DA levels were decreased. Adenosine and 5-HT levels were increased in all groups(P<0.05). After treatment,compared with the control group,the observation group had lower TCM syndrome score,ISI score,SAS score, and SDS score,longer total sleep time,higher sleep efficiency,shorter wake time and sleep latency,lower NSE and DA levels, and higher adenosine and 5-HT level (P<0.05). There was one case of nausea in the observation group and no adverse reaction in the control group during treatment. There was no significant difference between the two groups. ConclusionBy reducing NSE and DA and increasing the levels of 5-HT and adenosine,the anxiety (SAS score) and depression (SDS score) of patients can be improved, so as to improve their sleep and effectively treat chronic insomnia of liver depression and fire-turning type.

Chinese Medical Ethics 2023;36(5):561-567
【Objective:】 To explore the current situation and problems of village-level health human resource allocation based on the theory of policy change, and to help rural revitalization and healthy rural construction from the perspective of "consolidating the basic level foundation as fundamental policy". 【Methods:】 a) Information census method. A round-the-box survey on the distribution of health human resources at village-level in 14 rural towns and villages in H district was conducted. b) In-depth interview method. Based on the principle of information saturation, three township and villages clinics and community stations were selected for field observation, and in-depth personal interviews were conducted with key insiders. 【Results:】 The health policy environment changed significantly with the spatiotemporal changes. "Hollow village" and "inverted village" coexisted. The change of registered population and permanent resident population accelerated, old village doctors and new village doctors continued on the same hand, village clinics and community station were in "double track" of management progress. With the change of internal and external environment of the above-mentioned policies, the allocation of health human resources at village level needs to be studied urgently. 【Discussion:】 Under the dual function of external and internal environment, the policy change is inevitable. The health human resource distribution at village-level should be integrated with the system in terms of policy. The career development mechanism is connected up and down. Team construction revolves around suitable and applicable for batch training.

Chinese Journal of Hospital Administration 2023;39(3):230-233
As the " bottom" of the rural three-level medical and health network, the village clinic is the closest medical and health institution to the villagers. Through field research on H District of Beijing, the author found that the government implemented the management responsibility of village clinics by issuing health policies to carry out the standardization construction, strengthened the practice management of village doctors, and stabilized the income source of rural doctors, so that village doctors could better assume the functions of village level public health and prevention and treatment of common diseases. However, the unclear ownership relationship of village clinics and the labor relationship of village doctors, the differences in hardware configuration and the convergence of post responsibilities under different management systems affected the government′s implementation of the management responsibility of village clinics. Therefore, it could be necessary to pay attention to the change of policy environment, timely reform and mechanism integration of village clinics, and establish a career development mechanism connecting counties and villages. The bottleneck in the construction of village clinics will be broken, and the goal of " quality medical and health services nearby" for rural residents will be realized.
