The Effect of Female Sex on Short-Term Outcomes of Patients Undergoing Off-Pump Versus On-Pump Coronary Artery Bypass Grafting

ABSTRACT Introduction: According to the American Heart Association guideline for coronary artery bypass grafting (CABG), female patients undergoing on-pump CABG (ONCAB) are at higher risk of short-term adverse outcomes than male patients. However, whether off-pump CABG (OPCAB) can improve the short-term outcome of female patients compared to ONCAB remains unclear. Methods: We conducted a meta-analysis to study the effect of the female sex on short-term outcomes of OPCAB vs. ONCAB. A total of 31,115 patients were enrolled in 12 studies, including 20,245 females who underwent ONCAB and 10,910 females who underwent OPCAB. Results: The in-hospital mortality in female patients who underwent OPCAB was significantly lower than in those in the ONCAB group with (2.7% vs. 3.4%; odds ratio [OR] 0.76; 95% confidence interval [CI] 0.65-0.89) and without (OR 0.68; 95% CI 0.52-0.89) adjustment for cardiovascular risk factor. The incidence of postoperative stroke in female patients who underwent OPCAB was lower than in those in the ONCAB group (1.2% vs. 2.1%; OR 0.59; 95% CI 0.48-0.73) before cardiovascular risk factor adjustment but was not significant (OR 0.87; 95% CI 0,66-1.16) after adjustment. There was no significant difference in the incidence of postoperative myocardial infarction between women who underwent OPCAB and those in the ONCAB group (1.3% vs. 2.3%; OR 0.88; 95% CI 0.54-1.43). Conclusion: In contrast to the American Heart Association CABG guideline, female patients who had OPCAB don't have unfavorable outcomes compared with the ONCAB group.

OBJECTIVE@#To provide useful information for selecting the most appropriate peripheral nerve injury model for different research purposes in nerve injury and repair studies, and to compare nerve regeneration capacity and characteristics between them.@*METHODS@#Sixty adult SD rats were randomly divided into two groups and underwent crush injury alone (group A, n = 30) or transection injury followed by surgical repair (group B, n = 30) of the right hind paw. Each group was subjected to the CatWalk test, gastrocnemius muscle evaluation, pain threshold measurement, electrophysiological examination, retrograde neuronal labeling, and quantification of nerve regeneration before and 7, 14, 21, and 28 days after injury.@*RESULTS@#Gait analysis showed that the recovery speed in group A was significantly faster than that in group B at 14 days. At 21 days, the compound muscle action potential of the gastrocnemius muscle in group A was significantly higher than that in group B, and the number of labeled motor neurons in group B was lower than that in group A. The number of new myelin sheaths and the g-ratio were higher in group A than in group B. There was a 7-day time difference in the regeneration rate between the two injury groups.@*CONCLUSION@#The regeneration of nerve fibers was rapid after crush nerve injury, whereas the transection injury was relatively slow, which provides some ideas for the selection of clinical research models.

Current treatment landscape for obesity in Singapore

The rising prevalence of obesity in Singapore is a harbinger for a corresponding increase in obesity-related complications such as type 2 diabetes mellitus (T2DM) and coronary heart disease. Obesity is a complex disease driven by multiple factors, and hence, treatment cannot follow a 'one-size-fits-all' approach. Lifestyle modifications involving dietary interventions, physical activity and behavioural changes remain the cornerstone of obesity management. However, similar to other chronic diseases such as T2DM and hypertension, lifestyle modifications are often insufficient on their own, hence the importance of other treatment modalities including pharmacotherapy, endoscopic bariatric therapy and metabolic-bariatric surgery. Weight loss medications currently approved in Singapore include phentermine, orlistat, liraglutide and naltrexone-bupropion. In recent years, endoscopic bariatric therapies have evolved as an effective, minimally invasive and durable therapeutic option for obesity. Metabolic-bariatric surgery remains the most effective and durable treatment for patients with severe obesity, with an average weight loss of 25%-30% after one year.

The age ≥14 years, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers in patients, and oral hygiene was associated with the occurrence of bloodstream infection.

Transsphenoidal surgery for prolactinomas in male patients: a retrospective study / 亚洲男科学杂志(英文版)

Male patients with prolactinomas usually present with typical hyperprolactinemia symptoms, including sexual dysfunction and infertility. However, clinical factors related to sexual dysfunction and surgical outcomes in these patients remain unclear. This study aimed to investigate the outcomes of male patients with prolactinomas after transsphenoidal surgery and the risk factors affecting sexual dysfunction. This study was conducted on 58 male patients who underwent transsphenoidal surgery for prolactinomas between May 2014 and December 2020 at the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China. We evaluated the sexual function of patients before and after surgery through International Index of Erectile Function-5 scores, libido, and frequency of morning erection. Of the 58 patients, 48 (82.8%) patients had sexual intercourse preoperatively. Among those 48 patients, 41 (85.4%) patients presented with erectile dysfunction. The preoperative International Index of Erectile Function-5 scores in patients with macroprolactinomas were significantly higher than those in patients with giant prolactinomas (17.63 ± 0.91 vs 13.28 ± 1.43; P = 0.01). Postoperatively, the incidence of erectile dysfunction was 47.9%, which was significantly lower than that preoperatively (85.4%; P = 0.01). Twenty-eight (68.3%) patients demonstrated an improvement in erectile dysfunction. Tumor size and invasiveness were significantly correlated with the improvement of erectile dysfunction. Preoperative testosterone <2.3 ng ml-1 was an independent predictor of improvement in erectile dysfunction. In conclusion, our results indicated that tumor size and invasiveness were important factors affecting the improvement of sexual dysfunction in male patients with prolactinoma. The preoperative testosterone level was an independent predictor related to the improvement of erectile dysfunction.

Radiomics based on biparametric MRI for the detection of significant residual prostate cancer after androgen deprivation therapy: using whole-mount histopathology as reference standard / 亚洲男科学杂志(英文版)

We aimed to study radiomics approach based on biparametric magnetic resonance imaging (MRI) for determining significant residual cancer after androgen deprivation therapy (ADT). Ninety-two post-ADT prostate cancer patients underwent MRI before prostatectomy (62 with significant residual disease and 30 with complete response or minimum residual disease [CR/MRD]). Totally, 100 significant residual, 52 CR/MRD lesions, and 70 benign tissues were selected according to pathology. First, 381 radiomics features were extracted from T2-weighted imaging, diffusion-weighted imaging, and apparent diffusion coefficient (ADC) maps. Optimal features were selected using a support vector machine with a recursive feature elimination algorithm (SVM-RFE). Then, ADC values of significant residual, CR/MRD lesions, and benign tissues were compared by one-way analysis of variance. Logistic regression was used to construct models with SVM features to differentiate between each pair of tissues. Third, the efficiencies of ADC value and radiomics models for differentiating the three tissues were assessed by area under receiver operating characteristic curve (AUC). The ADC value (mean ± standard deviation [s.d.]) of significant residual lesions ([1.10 ± 0.02] × 10-3 mm2 s-1) was significantly lower than that of CR/MRD ([1.17 ± 0.02] × 10-3 mm2 s-1), which was significantly lower than that of benign tissues ([1.30 ± 0.02] × 10-3 mm2 s-1; both P < 0.05). The SVM feature models were comparable to ADC value in distinguishing CR/MRD from benign tissue (AUC: 0.766 vs 0.792) and distinguishing residual from benign tissue (AUC: 0.825 vs 0.835) (both P > 0.05), but superior to ADC value in differentiating significant residual from CR/MRD (AUC: 0.748 vs 0.558; P = 0.041). Radiomics approach with biparametric MRI could promote the detection of significant residual prostate cancer after ADT.

Investigation on the pharmacological mechanisms of Shirebi granules in treating gouty arthritis with damp-heat syndrome based on crosstalk of Wnt/β-catenin signaling / 药学学报

Gouty arthritis is a type of metabolic rheumatic disease caused by autoimmune abnormalities. Currently, the use of Western medicine in the clinical treatment of gouty arthritis has been associated with a high risk of adverse reactions. Therefore, there is a growing interest in exploring therapeutic drugs from traditional Chinese medicine as a potential alternative. According to the theory of traditional Chinese medicine, gouty arthritis has been classified as damp-heat arthralgia syndrome. Shirebi granules has been found to have good clinical efficacy in treating gouty arthritis. However, its underlying pharmacological mechanisms remain unclear. To address this problem, the study first established the interaction network of candidate targets for Shirebi granules, which is used to treat damp-heat syndrome of gouty arthritis. Then, the key candidate targets of Shirebi granules for treating gouty arthritis with damp-heat syndrome were screened by calculating the topological features of the network nodes. Then, the functional mining of the key candidate targets revealed that the candidate targets of Shirebi granules may intervene in the biological process of inflammatory response and lipid metabolism through the crosstalk of Wnt/β-catenin signaling. To verify the effectiveness of Shirebi granules in treating gouty arthritis with damp-heat syndrome, a rat model was established. The results demonstrated that the granules significantly improved the severity of arthritis in rats with this condition, reduced joint inflammation, gait score, swelling index, increased mechanical pain threshold (P < 0.05), and reduced the content of serum inflammatory factors IL-1β, IL-6, and TNF-α in gouty arthritis rats with damp-heat syndrome (P < 0.01) gouty. It was also found that Shirebi granules effectively alleviated the symptoms of dampness heat syndrome such as local joint fever and dry mouth by reducing the temperature of the joints in acute gouty arthritis with damp-heat syndrome (AD) rats, increasing the threshold of heat pain, increasing water intake (P < 0.01), and inhibiting abnormal changes in the content of fatty acid oxidation related enzymes (P < 0.01). Western blot analysis showed that Shirebi granules increased the protein expression levels of Wnt and β-catenin (P < 0.01) while decreasing the protein expression of p65, p-p65 and PPARγ (P < 0.01) in rats with gouty arthritis and damp-heat syndrome. The results showed that Shirebi granules may reverse the "inflammation-immune" imbalance and lipid metabolism disorder by regulating the crosstalk of Wnt/β-catenin signaling, and play a role in alleviating the severity of the disease. This study provides a methodological reference for elucidating the pharmacological mechanisms of traditional Chinese medicine formulas. It also presents research ideas for the appropriate clinical use of Chinese patent medicines and the development of new clinical drugs for gouty arthritis therapy. The animal welfare and experiment procedures of this study were performed in accordance with the regulations of the Experimental Animal Ethics Committee of Experimental Research Center, China Academy of Chinese Medical Sciences (grant No. ERCCACMS11-2302-08).

Curcumin Inhibits Viability of Clear Cell Renal Cell Carcinoma by Down-Regulating ADAMTS18 Gene Methylation though NF-κ B and AKT Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the effect of curcumin on viability of clear cell renal cell carcinoma (ccRCC) and analyze its possible mechanism.@*METHODS@#In cell lines of A498 and 786-O, the effects of curcumin (1.25, 2.5, 5 and 10 μ mol/L) on the viability of ccRCC were analyzed at 24, 48 and 72 h by MTT assay. The protein expression levels of ADAMTS18 gene, p65, phosphorylation p65 (pp65), AKT, phosphorylation AKT (pAKT) and matrix metallopeptidase 2 (MMP-2) before and after curcumin (10 μ mol/L) treatment were examined by Western blotting. Real-time PCR and methylation specific PCR (MSP) were applied to analyze the expression and methylation level of ADAMTS18 gene before and after curcumin treatment (10 μ mol/L).@*RESULTS@#Curcumin significantly inhibited the viability of A498 and 786-O cell lines in a dose- and time-dependent manner (P<0.01). Up-regulation of ADAMTS18 gene expression with down-regulation of ADAMTS18 gene methylation was reflected after curcumin treatment, accompanied by down-regulation of nuclear factor κ B (NF-κ kB) related protein (p65 and pp65), AKT related protein (AKT and pAKT), and NF-κ B/AKT common related protein MMP-2. With ADAMTS18 gene overexpressed, the expression levels of p65, AKT and MMP2 were downregulated, of which were conversely up-regulated in silenced ADAMTS18 (sh-ADAMTS18). The expression of pp65, pAKT and MMP2 in sh-ADAMTS18 was down-regulated after being treated with PDTC (NF-κ B inhibitor) and LY294002 (AKT inhibitor).@*CONCLUSIONS@#Curcumin could inhibit the viability of ccRCC by down-regulating ADAMTS18 gene methylation though NF-κ B and AKT signaling pathway.

Effects of polyol excipient stability during storage and use on the quality of biopharmaceutical formulations / 药物分析学报

Biopharmaceuticals are formulated using a variety of excipients to maintain their storage stability.However,some excipients are prone to degradation during repeated use and/or improper storage,and the impurities generated by their degradation are easily overlooked by end users and are usually not strictly monitored,affecting the stability of biopharmaceuticals.In this study,we evaluated the degra-dation profile of polyol excipient glycerol during repeated use and improper storage and identified an unprecedented cyclic ketal impurity using gas chromatography with mass spectrometry(GC-MS).The other polyol excipient,mannitol,was much more stable than glycerol.The effects of degraded glycerol and mannitol on the stability of the model biopharmaceutical pentapeptide,thymopentin,were also evaluated.The thymopentin content was only 66.4％in the thymopentin formulations with degraded glycerol,compared to 95.8％in other formulations after the stress test.Most glycerol impurities(i.e.,aldehydes and ketones)reacted with thymopentin,affecting the stability of thymopentin formulations.In conclusion,this work suggests that more attention should be paid to the quality changes of excipients during repeated use and storage.Additional testing of excipient stability under real or accelerated conditions by manufacturers would help avoid unexpected and painful results.

Mechanism of rhein inhibition of colorectal cancer through arginine metabolism based on protein chip / 药学学报

Rhein is an anthraquinone compound extracted from rhubarb, aloe vera, Polygonum multiflorum. In this study, we screened the potential targets of rhein through protein chip technology and investigated the underlying mechanism of its inhibition of colorectal cancer. Colony formation assay and scratch assay were used to examine the effect of rhein on the proliferation and migration abilities of HCT116 cell; KEGG and protein interaction analyses of rhein specific binding proteins by screening rhein binding proteins using protein chip; qRT-PCR and Western blot assays were used to determine the effect of rhein on the expression levels of BCL-2-associated X protein (BAX), B-cell lymphoma-2 (BCL-2) and argininosuccinate synthetase 1 (ASS1) in HCT116 cell. The antitumor effect of rhein was verified by azoxymethane combined with dextran sodium sulfate (AOM/DSS) induced colorectal cancer model. Experimental animal procedures were performed in accordance with animal welfare and the standards of the Laboratory Animal Ethics Committee of South China Agricultural University, with approval from the ethics committee. In vivo and in vitro results indicate that rhein specific binding proteins are mainly involved in amino acid anabolism, especially the arginine anabolic signaling pathway. Rhein inhibited the proliferation and migration of HCT116 cell in a concentration-dependent manner. Treated with rhein for 24 h significantly enhanced the expression of BAX and ASS1 in HCT116 cells, as well as the level of nitric oxide (NO) metabolism. In a mouse model of colorectal cancer, rhein significantly alleviated AOM/DSS induced weight loss and reduced fecal occult blood score. Meanwhile, rhein enhanced BAX and ASS1 expression in colon tumor tissue, as well as increased arginine and NO in serum. IHC and HE stain indicated that rhein alleviated Ki67 expression and macrophage infiltration in the colonic tissue of mice with AOM/DSS and delayed tumor formation. In conclusion, rhein can exert antitumor activity by regulating arginine and NO metabolism through ASS1.

Role of interaction between reactive oxygen species and ferroptosis pathway in methylglyoxal-induced injury in mouse embryonic osteoblasts / 南方医科大学学报

OBJECTIVE@#To explore the interaction between reactive oxygen species (ROS) and ferroptosis in methylglyoxalinduced injury of mouse embryonic osteoblasts (MC3T3-E1 cells).@*METHODS@#MC3T3-E1 cells were treated with methylglyoxal to establish a cell model of diabetic osteoporosis. CCK-8 assay was used to detect the viability of MC3T3-E1 cells. Rhodamine 123 staining followed by photofluorography was used to examine mitochondrial membrane potential (MMP). The intracellular ROS level was detected by 2', 7'-dichlorodihydrofluorescein diacetate staining with photofluorograph. Alkaline phosphatase (ALP) activity in the cells was detected using an ALP kit, the number of mineralized nodules was determined with alizarin red S staining, and the level of iron ions was detected using a detection kit. The expression level of glutathione peroxidase 4 (GPX4, a marker protein that inhibits ferroptosis) in the osteoblasts was determined using Western blotting.@*RESULTS@#Treatment of MC3T3-E1 cells with 0.6 mmol/L methylglyoxal for 24 h significantly inhibited the expression level of GPX4 (P < 0.001), increased intracellular iron ion concentration, decreased the cell viability, increased the loss of MMP and intracellular ROS level, decreased both ALP activity and the number of mineralized nodules in the cells (P < 0.001). Co-treatment of MC3T3-E1 cells with 2 mmol/L N-acetylcysteine (NAC, a ROS scavenger) and methylglyoxal significantly increased the expression level of GPX4 (P < 0.01); co-treatment with 4 mmo/L FER-1 (a ferroptosis inhibitor) and methylglyoxal obviously decreased the intracellular ROS level (P < 0.001). Co-treatment of the cells either with NAC and methylglyoxal or with FER-1 and methylglyoxal attenuated methylglyoxal-induced injuries in the osteoblasts (P < 0.001).@*CONCLUSION@#The interaction between ROS and ferroptosis pathway plays an important role in methylglyoxal-induced injury of mouse embryonic osteoblasts.

Diagnosis and management of polycystic ovary syndrome: Perspectives of clinicians in Singapore

INTRODUCTION@#To harmonise the diagnostic processes of polycystic ovary syndrome (PCOS) and enable clinicians to provide better patient care, it is critical to understand the knowledge gaps in PCOS diagnosis. We evaluated how clinicians in endocrinology, family medicine, general practice and gynaecology diagnose PCOS.@*METHODS@#This cross-sectional survey involved 208 clinicians from specific subspecialties across various healthcare settings in Singapore.@*RESULTS@#A total of 160 responses were included in the final analysis. Among all the diagnostic criteria, the Rotterdam 2003 criteria was most frequently used (66.3%). More than half of the gynaecologists reported having a standardised workplace protocol while the majority from other specialties reported otherwise. A large percentage of respondents (60.5%) were unable to identify the correct PCOS clinical features, which is concerning. Only 8.8% of respondents used clinical and biochemical hyperandrogenism, menstrual disturbances and pelvic ultrasound to diagnose PCOS without performing unnecessary and incorrect investigations. Most clinicians recognised insulin resistance/type 2 diabetes mellitus and fertility problems as complications while only a few recognised psychological complications. Many clinicians (37.3%) sought standardisation of PCOS diagnosis and management guidelines for improvement in PCOS care and 81.9% of respondents would appreciate standardised educational materials.@*CONCLUSION@#This is the first study to the best of our knowledge that gives an insight into the diagnostic and management processes of PCOS among various healthcare institutions in Singapore. This study calls for greater harmonisation of diagnostic processes and holistic evidence-based management of patients with PCOS through standardised workplace protocols and patient education resources.

Effects of Shaolin Neigong on the strength and stability of the forearm Rou-Kneading manipulation / 针灸推拿医学（英文版）

Objective: To collect, compare and analyze the changes in the strength and stability of the forearm Rou-Kneading manipulation before and after the training in Shaolin Neigong (internal Qigong). Methods: Ninety first-year undergraduates were randomized into three groups using the random number table method, with 30 people in each group. The Gongfa (Qigong method) group received training in both Shaolin Neigong and forearm Rou-Kneading manipulation. The manipulation group only received training in forearm Rou-Kneading manipulation. The control group only received training in forearm Rou-Kneading manipulation for one week. The ZTC-1 intelligent Tuina (Chinese therapeutic massage) manipulation parameter detection system was used to collect the wave crest, wave trough, and crest-trough difference of the strength and frequency of the forearm Rou-Kneading manipulation on the Z-axis (up and down), X-axis (left and right) and Y-axis (backward and forward) at weeks one, five and ten from the three groups. The collected data were then processed and analyzed. Results: The intra-group comparisons showed statistical significance in the Gongfa group and manipulation group (P<0.05). The strength and stability shown on the axes Z, X, and Y constantly grew with the increase of training time in the Gongfa group. The wave crest on the axes Z and Y steadily rose in the manipulation group, as well as the frequency on the axes Z, X and Y. The control group failed to show statistical significance in any of the three times of intra-group comparisons (P>0.05). The between-group comparisons showed statistical significance among the three groups at weeks five and ten (P<0.05). At week five, the wave crest on the axes Z, X, and Y, and the crest-trough difference on the axes X and Y were more prominent in the Gongfa group than in the manipulation group, showing statistical significance (P<0.05). At week ten, the wave crest, wave trough, and crest-trough differences on the axes Z, X, and Y were more prominent in the Gongfa group than in the manipulation group, presenting statistical significance (P<0.05). Conclusion: Practicing Shaolin Neigong can help the trainees reach the level of strength and frequency of Tuina clinicians in a shorter time in the forearm Rou-Kneading manipulation training. It can advance the efficiency in studying the forearm Rou-Kneading manipulation and promote the quality of the manipulation.

Effect of Sinisan on BDNF/TrkB， 5-HT/5-HT1AR， and HPA axis in Depression Model Rats / 中国实验方剂学杂志

Objective:To observe the effect of Sinisan on the brain-derived neurotrophic factor （BDNF）/tyrosine kinase receptor B （TrKB）， 5-hydroxytryptamine （5-HT）/5-HT1A receptor （5-HT1AR）， and hypothalamus-pituitary-adrenal （HPA） axis in depressed rats， and explore the antidepressant mechanism of Sinisan based on BDNF/TrKB， 5-HT/5-HT1AR， and HPA axis. Method:A total of 120 male Wistar rats were randomly divided into a normal group， a model group， a fluoxetine （0.01 g·kg^-1） group， and low- （1.25 g·kg^-1）， medium- （2.5 g·kg^-1）， and high-dose （5 g·kg^-1） Sinisan groups， with 20 rats in each group. The depression model was induced by isolation combined with chronic unpredictable mild stimulation（CUMS） in rats except for those in the normal group for 21 days. Rats were then treated correspondingly once a day for 21 days by gavage. Those in the normal group and the model group received an equal volume of normal saline. During the intervention， the model rats were stimulated continuously. The depressive state of CUMS model rats was evaluated by sucrose preference test and open field test. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of corticotropin-releasing hormone （CRH）， adrenocorticotropic hormone （ACTH）， and corticosterone （CORT） in the plasma and BDNF and 5-HT levels in the hippocampal homogenate. The mRNA expression of hippocampal TrKB， 5-HT1AR， glucocorticoid receptor （GR）， and mineralocorticoid receptor （MR） was detected by real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR）. The protein expression of hippocampal TrKB， 5-HT1AR， GR， and MR was detected by Western blot. The histomorphological changes of the hippocampus were observed by hematoxylin-eosin （HE） staining. Result:Compared with the normal group， the model group showed decreased sucrose preference rate （<italic>P</italic><0.01）， reduced horizontal and vertical scores in the open field test （<italic>P</italic><0.01）， increased plasma content of CRH， ACTH， and CORT （<italic>P</italic><0.01）， declining content of BDNF and 5-HT in the hippocampus （<italic>P</italic><0.01）， dwindled mRNA and protein expression levels of TrKB， 5-HT1AR， and GR （<italic>P</italic><0.01）， elevated mRNA and protein expression of MR （<italic>P</italic><0.01）， and damaged hippocampal neurons revealed by HE staining. Compared with the model group， the groups with drug intervention showed increased sucrose preference rate （<italic>P</italic><0.01） and horizontal and vertical scores in the open field test （<italic>P</italic><0.05， <italic>P</italic><0.01）， decreased content of plasma CRH， ACTH， and CORT （<italic>P</italic><0.05， <italic>P</italic><0.01）， elevated content of hippocampal BDNF and 5-HT （<italic>P</italic><0.05， <italic>P</italic><0.01）， elevated mRNA and protein expression levels of hippocampal TrKB， 5-HT1AR， and GR （<italic>P</italic><0.05， <italic>P</italic><0.01）， reduced mRNA and protein expression levels of hippocampal MR （<italic>P</italic><0.05， <italic>P</italic><0.01）， and recovered hippocampal neurons as revealed by HE staining. Conclusion:Sinisan can exert a significant antidepressant effect by increasing hippocampal BDNF and 5-HT content， up-regulating TrKB， 5-HT1AR， and GR mRNA and protein expression， down-regulating MR mRNA and protein expression， inhibiting HPA axis hypertrophy， and enhancing the regeneration and repair of hippocampal neurons.

Multidisciplinary and Comprehensive Chinese Medicine for Advanced Non-Small Cell Lung Cancer Patients: A Retrospective Study of 855 Cases / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of multidisciplinary and comprehensive Chinese medicine (CM) treatments on progression-free survival (PFS) and median survival time (MST) in patients with advanced non-small cell lung cancer (NSCLC) and identify factors that influence progression and prognosis.@*METHODS@#Clinical data of 855 patients with advanced NSCLC who received multidisciplinary and comprehensive CM treatments at Longhua Hospital from January 2009 to December 2018 were retrospectively analyzed. Univariate analysis was performed by the Kaplan-Meier method and log-rank sequential inspection. Multivariate analysis of significant variables from the univariate analysis was performed with Cox regression modeling. Key factors correlated to progression and prognosis were screened out, and a Cox proportional hazard model was established to calculate the prognostic index.@*RESULTS@#The PFS and MST of 855 advanced NSCLC patients were 9.0 and 26.0 months, respectively. The 1-, 2-, 3-, and 5-year survival rates were 79.2%, 54%, 36.2%, and 17.1%, respectively. Gender, pathologic type, and clinical stage were independent prognostic risk factors; surgical history, radiotherapy, treatment course of Chinese patent medicine, intravenous drip of Chinese herbal preparation, duration of oral administration of Chinese herbal decoction (CHD), and intervention measures were independent prognostic protective factors. Gender was an independent risk factor for progression, while operation history and oral CHD administration duration were independent protective factors (all P<0.05). Women with stage IIIb-IIIc lung adenocarcinoma had the best outcomes.@*CONCLUSIONS@#Female patients have lower progression risk and better prognoses than male patients, younger patients have higher progression risk but better long-term prognoses than the elderlys, and patients with lower performance status scores are at lower risk for progression and have better prognoses. Comprehensive CM treatments could significantly reduce progression risk, improve prognosis, and prolong survival time for patients with advanced NSCLC. This treatment mode offers additional advantages over supportive care alone.

A cross-sectional survey of patients with diabetic foot in Jinyang Community of Shanghai / 上海预防医学

Objective:To determine the current situation of patients with diabetic foot and influencing factors in Jinyang community of Shanghai. Methods:A total of 1400 patients with diabetes registered in community management from January 2019 through December 2019 were randomly selected for survey. All patients completed the screen for diabetic foot and then were divided into control group （n=159） and observation group （n=1 241） according to the occurrence of diabetic foot. Patient's demographics and medical history were recorded， including gender， age， history of long-term smoking， course of disease， history of trauma infection， fasting blood glucose， 2 h postprandial blood glucose （2hPG）， glycosylated hemoglobin （HbAlc）， blood lipid level， history of hyperglycemia， diabetic nephropathy， and diabetic retinopathy. Univariate and multivariate logistic analyses were performed with these possible influencing factors. Results:Univariate analysis showed that the incidence of diabetic foot was not significantly associated with gender， age， history of trauma infection， course of disease or blood lipid level （P>0.05）， whereas had statistical significance with long-term smoking history， fasting blood glucose and 2-hour diabetes mellitus PG， HbAlc， history of hypertension， diabetic nephropathy and diabetic retinopathy （P<0.05）. Multivariate logistic analysis showed that the incidence of diabetic foot was not statistically associated with gender， age， history of trauma infection， course of disease or blood lipid level （P>0.05）； it was significantly associated with long-term smoking history， fasting blood glucose and 2-hour diabetes mellitus PG， HbAlc， history of hypertension， diabetic nephropathy and diabetic retinopathy （P<0.05）. Conclusion:There are multiple influencing factors of diabetic foot in Jinyang community. We should take corresponding measures to control the blood glucose level of diabetic patients and reduce the incidence of diabetic foot.
