Effects of laparoscopic hyperthermic intraperitoneal perfusion chemotherapy combined with intraperitoneal and systemic chemotherapy treatment in patients with untreated gastric cancer with peritoneal metastasis / 中华胃肠外科杂志

Objective: To investigate the efficacy of laparoscopic hyperthermic intraperitoneal perfusion chemotherapy combined with intraperitoneal and systemic chemotherapy (HIPEC-IP-IV) in the treatment of peritoneal metastases from gastric cancer (GCPM). Methods: This was a descriptive case series study. Indications for HIPEC-IP-IV treatment include: (1) pathologically confirmed gastric or esophagogastric junction adenocarcinoma; (2) age 20-85 years; (3) peritoneal metastases as the sole form of Stage IV disease, confirmed by computed tomography, laparoscopic exploration, ascites or peritoneal lavage fluid cytology; and (4) Eastern Cooperative Oncology Group performance status 0-1. Contraindications include: (1) routine blood tests, liver and renal function, and electrocardiogram showing no contraindications to chemotherapy; (2) no serious cardiopulmonary dysfunction; and (3) no intestinal obstruction or peritoneal adhesions. According to the above criteria, data of patients with GCPM who had undergone laparoscopic exploration and HIPEC from June 2015 to March 2021 in the Peking University Cancer Hospital Gastrointestinal Center were analyzed, after excluding those who had received antitumor medical or surgical treatment. Two weeks after laparoscopic exploration and HIPEC, the patients received intraperitoneal and systemic chemotherapy. They were evaluated every two to four cycles. Surgery was considered if the treatment was effective, as shown by achieving stable disease or a partial or complete response and negative cytology. The primary outcomes were surgical conversion rate, R0 resection rate, and overall survival. Results: Sixty-nine previously untreated patients with GCPM had undergone HIPEC-IP-IV, including 43 men and 26 women; with a median age of 59 (24-83) years. The median PCI was 10 (1-39). Thirteen patients (18.8%) underwent surgery after HIPEC-IP-IV, R0 being achieved in nine of them (13.0%). The median overall survival (OS) was 16.1 months. The median OS of patients with massive or moderate ascites and little or no ascites were 6.6 and 17.9 months, respectively (P<0.001). The median OS of patients who had undergone R0 surgery, non-R0 surgery, and no surgery were 32.8, 8.0, and 14.9 months, respectively (P=0.007). Conclusions: HIPEC-IP-IV is a feasible treatment protocol for GCPM. Patients with massive or moderate ascites have a poor prognosis. Candidates for surgery should be selected carefully from those in whom treatment has been effective and R0 should be aimed for.

Clinical characteristics of children with SARS-CoV-2 Omicron variant infection in Kunming / 中华儿科杂志

Objective: To investigate the clinical characteristics of hospitalized children infected with the Omicron variant in Kunming after the withdrawal of non-pharmaceutical interventions (NPI) and analyze the risk factors of severe cases. Methods: Clinical data was retrospectively collected from 1 145 children with SARS-CoV-2 Omicron infection who were hospitalized in six tertiary grade A hospitals in Kunming from December 10th, 2022 to January 9th, 2023. According to clinical severity, these patients were divided into the general and severe SARS-CoV-2 groups, and their clinical and laboratory data were compared. Between-group comparison was performed using t-test, chi-square test and Mann-Whitney U test. Spearman correlation test and multivariate Logistic regression analysis were used to determine the risk factors of severe illness. Results: A total of 1 145 hospitalized patients were included, of whom 677 were male and 468 female. The age of these patients at visit was 1.7 (0.5, 4.1) years. Specifically, there were 758 patients (66.2%) aged ≤3 years at visit and 387 patients (33.8%) aged >3 years. Of these children, 89 cases (7.8%) had underline diseases and the remaining 1 056 cases (92.2%) had no combined diseases. Additionally, of all the patients, 319 cases (27.9%) were vaccinated with one or two doses of SARS-CoV-2 vaccine, 748 cases (65.3%) had acute upper respiratory tract infection (AURTI), and six cases died (0.5%). A total of 1 051 cases (91.8%) were grouped into general SARS-CoV-2 group and 94 cases (8.2%) were grouped into severe SARS-CoV-2 group. Compared with the general cases, the severe cases showed a lower rate of SARS-CoV-2 vaccination and younger median age, lower lymphocyte count, as well as proportions of CD8+T lymphocyte (36 cases (38.3%) vs. 283 cases (26.9%), 0.5 (2.6, 8.0) vs. 1.6 (0.5, 3.9) years, 1.3 (1.0, 2.7) ×109 vs. 2.7 (1.3,4.4)×109/L, 0.17 (0.12, 0.24) vs. 0.21 (0.15, 0.16), respectively, χ2=4.88, Z=-2.21,-5.03,-2.53, all P<0.05). On the other hand, the length of hospital stay, proportion of underline diseases, ALT, AST, creatine kinase isoenzyme, and troponin T were higher in the severe group compared to those in the general group ((11.6±5.9) vs. (5.3±1.8) d, 41 cases (43.6%) vs. 48 cases (4.6%), 67 (26,120) vs. 20 (15, 32) U/L, 51 (33, 123) vs. 44 (34, 58) U/L、56.9 (23.0, 219.3) vs. 3.6 (1.9, 17.9) U/L, 12.0 (4.9, 56.5) vs. 3.0 (3.0, 7.0) ×10-3 pg/L,respectively, t=-20.43, χ2=183.52, Z=-9.14,-3.12,-6.38,-3.81, all P<0.05). Multivariate regression analysis indicated that increased leukocyte count (OR=1.88, 95%CI 1.18-2.97, P<0.01), CRP (OR=1.18, 95%CI 1.06-1.31, P<0.01), ferritin (OR=1.01, 95%CI 1.00-1.00, P<0.01), interleukin (IL)-6 (OR=1.05, 95%CI 1.01-1.08, P=0.012), D-dimer (OR=2.56, 95%CI 1.44-4.56, P<0.01) and decreased CD4+T lymphocyte (OR=0.84, 95%CI 0.73-0.98, P=0.030) were independently associated with the risk of severe SARS-CoV-2 in hospitalized children with Omicron infection. Conclusions: After the withdrawal of NPI, the pediatric inpatients with Omicron infection in Kunming were predominantly children younger than 3 years of age, and mainly manifested as AURTI with relatively low rate of severe SARS-CoV-2 infection and mortality. Elevated leukocyte counts, CRP, ferritin, IL-6, D-dimer, and decreased CD4+T lymphocytes are significant risk factors for developing severe SARS-CoV-2 infection.

Methods:A total of 64 patients with isolated coronary artery muscular bridge angina pectoris with qi deficiency and blood stasis syndrome in Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University from April 2016 to January 2020 who met the inclusion criteria were divided into 2 groups by random number table method, with 32 patients in each group. The control group took diltiazem hydrochloride tablets orally, and the treatment group took Yiqi-Tongmai Decoction on the basis of the control group. Both groups were treated for 8 weeks. The TCM syndrome scores were observed before and after treatment, and Seattle Angina Questionnaire was assessed for patient's quality of life and functional status. The exercise ECG test was observed before and after treatment, and the cause of angina pectoris need to be recorded, including the movement time and plate movement caused by time of ST segment in electrocardiogram (ecg) and dynamic evolution. Results:The total effective rate of angina pectoris was 84.38% (27/32) in the treatment group, and 53.13% (17/32) in the control group, and the difference between the two groups was statistically significant ( χ2=8.09, P<0.05). After treatment, the degree of physical activity limitation (69.24 ± 14.21 vs. 59.42 ± 11.71, Z=-2.61), stable state of angina (82.25 ± 21.24 vs. 69.11 ± 19.52, Z=2.64), angina (80.24 ± 18.31 vs. 69.11 ± 15.54, Z=2.63), treatment satisfaction (86.16 ± 19.23 vs. 61.19 ± 17.35, Z=2.22), degree of disease cognition (74.41 ± 21.13 vs. 60.43 ± 19.42, Z=2.40) scores in the treatment group were significantly higher than those in the control group ( P<0.05). In the treatment group, the time of exercise-induced angina pectoris [(476.15 ± 62.15)s vs. (399.38 ± 78.42)s, Z=-2.08], the time of ST segment descending 1 mm after exercise [(394.54 ± 75.61)s vs. (309.64 ± 81.62)s, Z=-2.40] in the treatment group were significantly longer than those in the control group ( P<0.05). The total effective rate of TCM syndrome was 93.8% (30/32) in the treatment group and 65.6% (21/32) in the control group, and the difference was statistically significant ( χ2=7.96, P<0.05). The TCM syndrome scores of the treatment group (25.15 ± 6.15 vs. 36.38 ± 10.42, Z=-2.56) in the treatment group were significantly lower than that of the control group ( P<0.05). There were no obvious adverse reactions in both groups during treatment. Conclusion:Yiqi-Tongmai Decoction can improve the clinical symptoms of isolated coronary artery muscle bridge angina pectoris with qi deficiency and blood stasis syndrome, reduce the onset of angina pectoris, delay the time of exercise induced angina pectoris, and improve the clinical efficacy.

The mechanisms of type 2 diabetic skeletal muscle atrophy and the effects of commonly used hypoglycemic drugs: a review / 药学学报

Type 2 diabetes is a hypermetabolic disease characterized with disorders of glucose/lipid metabolism, absolute or relative lack of insulin, and can induce skeletal muscle atrophy. Hyperglycemia, hyperlipidemia, insulin resistance, and abnormal release of inflammatory factors can lead to abnormal signal transduction in skeletal muscle, thus make protein synthesis and degradation imbalance and eventually causing muscle atrophy. Under normal conditions, insulin-like growth factor 1 (IGF-1)/insulin can activate phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT). AKT not only increases protein synthesis through mammalian target protein of rapamycin (mTOR), but also phosphorylates forkhead box O (FoxO) transcription factor and then inhibits the transcription of several ubiquitin ligases (such as MAFbx/atrogin-1 and MuRF1), or autophagy related genes. The weakened IGF-1/PI3K/AKT pathway in type 2 diabetes is an important factor leading to skeletal muscle atrophy. Studies have shown that the commonly used anti-type 2 diabetic drugs have different effects in regulating the synthesis and degradation of skeletal muscle protein. Studies reported that drugs with effect of anti-diabetic muscle atrophy include thiazolidinediones, glucagon-like peptide analogs, glucose-sodium cotransporter 2 inhibitors, etc.; drugs that are still in controversial or even promote skeletal muscle atrophy include metformin, and some sulfonylurea or non-sulfonylurea insulin secretagogues. This article overviewed and analyzed the currently commonly used drugs for type 2 diabetes and summarized the related mechanisms, with the aim to provide references for the rational applications of drugs for type 2 diabetes.

Knowledge about, attitude and acceptance towards, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China: A cross-sectional survey / 中西医结合学报

OBJECTIVE@#The coronavirus disease 2019 (COVID-19) pandemic has had a serious impact on health all over the world. Cancer patient, whose immunity is often compromised, faces a huge challenge. Currently, some COVID-19 vaccines are being developed and applied on general population; however, whether cancer patients should take COVID-19 vaccine remains unknown. Our study aimed to explore the knowledge, attitude, acceptance, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China.@*METHODS@#A cross-sectional study was conducted in Eastern China from June 17th to September 3rd, 2021. Patients were selected using a convenience sampling method. A self-report questionnaire was developed to assess knowledge about the COVID-19 vaccine, attitude towards the vaccine and acceptance of the vaccine; following a review of similar studies previously published in the scientific literature, multivariate logistic regression analysis was used to determine the predictors associated with COVID-19 vaccine acceptance.@*RESULTS@#A total of 2158 cancer patients were enrolled in this study. The rate of vaccine hesitancy was 24.05% (519/2158); further, among the participants of vaccine acceptance, 767 had taken COVID-19 vaccine (35.54%), and 872 were willing to get vaccinated (40.01%). A total of 24 variables including demographic characteristics, clinical status of cancer, impact of COVID-19 pandemic on study participants, patients' knowledge about the COVID-19 vaccine, and attitude towards the vaccine, had significant differences between the "vaccine hesitancy" population and "vaccine acceptance" population. Multivariate logistic regression analysis indicated that parameters including alcohol consumption (odds ratio [OR] = 1.849; 95% confidence interval [CI]: 1.375-2.488; P-reference [P-Ref] < 0.001 vs non-drinkers), income impacted by COVID-19 pandemic (OR = 1.930, 2.037 and 2.688 for mild, moderate, and severe impact, respectively; all P-Ref < 0.01 vs no impact), knowledge of how the vaccine was developed (OR = 1.616; 95% CI: 1.126-2.318; P-Ref = 0.009 vs unknown), believing in the safety of the vaccine (OR = 1.502; 95% CI: 1.024-2.203; P-Ref = 0.038 vs denying the safety of vaccine), willingness to pay for the vaccine (OR = 3.042; 95% CI: 2.376-3.894; P-Ref < 0.001 vs unwilling), and willingness to recommend families and friends to get vaccinated (OR = 2.744; 95% CI: 1.759-4.280; P-Ref < 0.001 vs do not recommend) were contributors to vaccine acceptance. While such as being retired (OR = 0.586; 95% CI: 0.438-0.784; P-Ref < 0.001 vs unemployed), undergoing multiple therapies of cancer (OR = 0.408; 95% CI: 0.221-0.753; P-Ref = 0.004 vs no ongoing treatment), and worrying that the vaccine might deteriorate the prognosis of cancer (OR = 0.393; 95% CI: 0.307-0.504; P-Ref < 0.001 vs might not) were contributors to vaccine hesitancy.@*CONCLUSION@#This study provided preliminary estimates of the rates of vaccine acceptance and vaccine hesitancy among cancer patients in Eastern China. The intention to receive the COVID-19 vaccine was impacted by factors such as patient occupation, alcohol consumption, and some parts of knowledge about and attitude towards COVID-19 vaccine. It is recommended to develop individualized vaccination plans that meet the healthcare needs of cancer patients.

Young Children's Family Sex Education in Rural Areas of Sichuan Province and Its Influencing Factors / 中国医学科学院学报

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

Regulatory effect of polar extract of Poria cocos on neurotransmitter and circadian rhythm disorder in CUMS rats / 中草药

Objective: To explore the regulation of polar extract of Poria cocos on neurotransmitter and circadian rhythm metabolic pathway. Methods: Male SD rats were randomly divided into blank group, chronic unpredictable mild stress (CUMS) model group, positive drug venlafaxine hydrochloride group (35 mg/kg), and polar extract of P. cocos group (15 g/kg). Rats were modeled and ig administrated for 28 d simultaneously, and the body weight, sugar preference rate, and opening behavior were observed dynamically after administration. The levels of tryptophan (Trp), 5-hydroxytryptophan (5-HT), and 5-hydroxyindole acetic acid (5-HIAA), noradrenaline (NE), dopamine (DA), acetylcholiner (Ach), γ-aminobutyric acid (GABA), glutamic acid (Glu), the proportion of GABA/Glu in serum were measured by LC-MS. The expression of key genes in the circadian rhythm pathway in liver tissue was detected by using qRT-PCR. Results: Polar extracts of P. cocos significantly improved the abnormality of the sugar preference rate and opening behavior. And polar extracts of P. cocos significantly restored the levels of 5-HT, 5-HIAA, Trp, NE, Ach, GABA, the proportion of GABA/Glu in serum and regulated the gene expression levels of Arntl, Per1, Per2, Per3, and Nr1d1 in hepatocyte. Conclusion: The polar extract of P. cocos could improve neurotransmitters and circadian rhythm disorders in CUMS rats through enhancing the 5-HT metabolic pathway, regulating Ach-NE signaling interaction and the equilibrium of proportion of amino acids neurotransmitter and restoring the expression levels of Arntl, Per1, Per2, Per3, and Nr1d1 involved in the circadian rhythm.

Antidepressant-like effects of the petroleum ether fraction of Xiaoyaosan in the CUMS rat model of depression / 药学学报

This study aimed to investigate the effect of the petroleum ether fraction of Xiaoyaosan (XY-A) in a rat depression model with consideration of an underlying mechanism based on gut microbiota and metabolomics. All procedures involving animal treatment were approved according to the Committee on the Ethics of Animal Experiments of Shanxi University. A rat model was established using the chronic unpredictable mild stress (CUMS) procedure and XY-A and venlafaxine (positive control) were used as intervention drugs. Sequencing of the 16S rRNA gene combined with LC-MS metabolomics was used to investigate the effects of XY-A on gut microbiota and metabolites in CUMS-induced depression, and Pearson correlation analysis was carried out on gut microbiota and metabolites. The results showed that XY-A significantly improved the depression-like behavior of CUMS rats and restored the level of brain-derived neurotrophic factor (BDNF) in the hippocampus. Gut microbiota analysis revealed that XY-A can increase the diversity of microbial species in CUMS rats and significantly restored the relative abundance of intestinal Rothia [Prevotella], with effects on intestinal inflammation and the production of short-chain fatty acids. Cecal content metabolomics identified twenty biomarkers that were altered by depression, whereas administration of XY-A ameliorated the changes in seventeen metabolites, with the most strongly affected metabolic pathways being linoleic acid metabolism, taurine and hypotaurine metabolism, primary bile acid biosynthesis, and arginine and proline metabolism. Correlation analysis further showed that there was a strong relationship between the gut microbiota and the cecal content metabolites. In summary, XY-A may exert antidepressant effects by regulating the composition of the gut microbiota and the metabolites and pathways of the cecum. The results provide a reference for the potential molecular mechanism of antidepressant action of XY-A.

Biological assay in quality control of animal medicines / 中国中药杂志

Animal medicine is a unique part of traditional Chinese medicine. They have strong effects, but their effective compounds are not entirely known. The efficiency and safety of animal medicines can't be effectively controlled by current quality assurance system and evaluation method, which has deeply influenced the development of animal medicines. Biological assay does not focus on efficacy of single component, but directly reflects the pharmacodynamics and safety of animal medicines by biological effect. With the development of biotechnology, many new technologies have emerged, such as biochip and high content analysis. Based on the related targets, pathways and key biochemical factors, the field of biological assay has been expanded. With advantages of pharmacology andoverall controllability, as well as the characteristics of in line with the quality control of Chinese Medicine, biological assay will become one of the important development directionsfor quality standardization of animal medicines.

Improved Fertility Following Enucleation of Intramural Myomas in Infertile Women / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The relationship between intramural myomas and fertility remains unclear. The main debate rests on whether cavity-distorting intramural myomas (CDMs) adversely affect fertility more than non-CDMs. We aimed to compare the effects of enucleating non-CDMs and CDMs on fertility improvement in females with unexplained infertility.</p><p><b>METHODS</b>We prospectively recruited 83 women undergoing myomectomy for unexplained infertility with intramural myomas between June 2008 and November 2012 and classified them into non-CDMs group (n = 45) and CDMs group (n = 38). We then compared postoperative infertility rates, spontaneous pregnancy rates, pregnancy outcomes, live birth rates, and obstetric complications. For continuous variables, we calculated the mean ± standard deviation, median and interquartile range, and analyzed the data using Student's t-test and the Mann-Whitney U-test. For categorical variables, the Pearson's Chi-square test, the continuity correction test, and Fisher's exact test were used.</p><p><b>RESULTS</b>Patients' demographics and myoma characteristics were comparable between the two groups. The overall spontaneous pregnancy rate increased from 0% to 68.42% following myomectomy. The postoperative infertility rate was significantly higher in the non-CDMs group than that in the CDMs group (50.00% vs. 23.53%, t = 5.579, P = 0.018), whereas the postoperative spontaneous pregnancy rate was significantly lower in the non-CDMs group than that in the CDMs group (47.62% vs. 70.59%, t = 4.067, P = 0.044). Compared with the enucleation of non-CDM, the enucleation of CDM patients was a protective factor for the fertility restoration (risk ratio [RR] = 3.717, 95% confidence interval [CI]: 1.284-10.753, P = 0.015), although postoperative fertility restoration declined with age (RR = 1.141, 95% CI: 1.005-1.295, P = 0.041).</p><p><b>CONCLUSIONS</b>Intramural myomas are associated with impaired fertility. Women experiencing unexplained infertility, and possessing intramural myomas, have a better chance of conception following myomectomy, and these benefits are more obvious for younger patients and patients with CDM.</p>

Comparative Analysis of 2000～2010 Epidemiological Survey of Childhood Asthma in Kunming City, China / 昆明医科大学学报

Objectives To investigate the prevalence of childhood asthma in 2000～2010,to find the changes of childhood asthma in distribution characteristics,precipitating factors,diagnosis and treatment status,and to provide scientific data for the improvement of the prevention and management of asthma in children in Kunming city,China.Methods Children were selected by random cluster sampling.Standardized preliminary questionnaire was used for screening out possible patients in the two surveys of 2000 and 2010.Diagnosis of asthma was confirmed by diagnostic criteria in suspected asthmatic children.Asthmatic children were further asked for past diagnosis and treatment with the questionnaire of asthma in children.Double entry and validation were adopted for all data and analysis was carried out using Epi-Info software.Results Compared with 2000,the total asthma incidence rate increased significantly from 0.88％ to 1.40％ (x 2=12.52,P＜0.05),the coincidence rate of final diagnosis and previous diagnosis increased from 22.8％ to 51.3％ (x2 =19.23,P ＜0.05) and the proportion of acute exacerbation of asthma reduced from 40.2％ to 19.3％ (x 2 =12.54,P＜0.05) in 2010.Compared with 2000,Antibiotics use rate reduced from 97.8％ to 80.0％ (x 2=14.28,P ＜0.05) and the proportion of inhaled corticosteroid increased from 12.0％ to 64.0％ (x 2=60.53,P＜0.05).Conclusion Compared with 10 years ago,the total asthma incidence of childhood asthma aged 0 ～ 14 year old in Kunming city was significantly increased.The coincidence rate of final diagnosis and previous diagnosis increased and the proportion of acute exacerbation of asthma reduced.Antibiotics use rate reduced and the proportion of inhaled corticosteroid increased.The treatment and management of asthma in children awaits improvement as well,especially in reducing the rate of missed diagnosis in children with asthma and regulating the use of corticosteroids and bronchodilators inhaling treatment and reduces the use of the proportion of antibiotics.
