Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To systematically assess the effectiveness and safety of acupuncture for spastic hemiplegia after ischemic stroke. Methods:Randomized controlled trials(RCTs)of acupuncture treatment for spastic hemiplegia after ischemic stroke meeting the inclusion criteria in Cochrane Library,Medline,Excerpta Medica Database(EMBASE),PubMed,China National Knowledge Infrastructure(CNKI),SinoMed,Chongqing VIP Database(VIP),and Wanfang Data Knowledge Service Platform(Wanfang)published from each database's inception to February 2023 were retrieved by computer.Two reviewers independently extracted data and evaluated the risk of bias using Cochrane's risk of bias tool.Review Manager 5.4 was used for data analysis.Continuous data were evaluated using mean difference(MD)with a 95%confidence interval(CI),and dichotomous data were analyzed using risk ratio(RR). Results:A total of 24 trials,including 1 970 participants,were included in the study.The meta-analysis of 7 trials showed that compared to the rehabilitation therapy,acupuncture therapy was more effective in improving the simplified Fugl-Meyer assessment score after 1-month treatments[MD=10.52,95%CI(7.81,13.23),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.18,95%CI(11.34,27.02),P<0.001],and the 6-month treatment course resulted in better outcomes than the 1-month course.The meta-analysis of 8 trials showed that acupuncture had a better improvement on the Barthel index score than rehabilitation therapy after 1-month treatments[MD=10.78,95%CI(8.91,12.64),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.94,95%CI(19.02,20.87),P<0.001],and the 6-month course was better than the 1-month course.The meta-analysis of 2 trials showed that the effective rate of the modified Ashworth scale score improvement was more notable in the acupuncture group after 1-month treatments[RR=1.20,95%CI(1.02,1.40),P=0.020].One trial reported no adverse event,and 1 trial reported 3 adverse events without severe influence. Conclusion:Acupuncture might be an effective and safe therapy for spastic hemiplegia after ischemic stroke,but more high-quality,large-sample objectively-evaluated RCTs are needed to validate the conclusion.

Malignancies are diseases resulting from an imbalance of cell growth and proliferation， endangering human health and life. Currently， there is no clinically effective treatment for tumors. Tumor cells may alter cell adhesion and tumor cell migration and movement by degrading the extracellular matrix， generating vascular factors， affecting epithelial-mesenchymal transformation， or altering the tumor microenvironment. The mechanisms which lead to multidrug resistance （MDR） are the regulation of membrane proteins， apoptosis-regulated gene expression， enzyme-mediated multidrug resistance， DNA damage repair， and epithelial-stromal transformation， resulting in ineffective treatment of tumors. Therefore， the search for natural， safe， and effective chemosensitizers has become a critical part in tumor research. Due to the increasing use of Chinese medicine in cancer treatment， researchers have conducted more extensive studies on its monomers and compounds. In addition， the mechanisms of Chinese medicine in inhibiting tumor invasion and metastasis and reversing drug resistance are gradually unraveled. The monomers and compounds of Chinese medicine may inhibit tumor invasion， metastasis， and drug resistance by enhancing the sensitivity of chemotherapy drugs and adjuvant properties. Furthermore， they can also improve the tolerance of patients to chemotherapy drugs， relieve side effects of chemotherapy， reduce the chance of recurrence， and prolong the life of patients. The development of traditional Chinese medicine plays an important role in reducing tumor recurrence and metastasis， reversing drug resistance， prolonging the prognosis of cancer patients， improving their quality of life， and prolonging their survival time. Currently， various types of Chinese medicines have been proven to be capable of reducing tumor invasion and metastasis， and reversing drug resistance. The present article reviewed development and findings of Chinese medicine as an anti-tumor invasion， anti-metastasis， and anti-tumor resistance therapy in recent years， in order to provide ideas for future research on anti-tumor effect of active components in Chinese medicine.

Objective To analyze the incidence and risk factors of hypocalcemia after total parathyroidectomy without autotransplantation. Methods A total of 783 maintenance hemodialysis patients who underwent TPTX in the Second Affiliated Hospital of Nanjing Medical University from September 2008 to September 2017 were included in the study. The preoperative blood biochemical examination, preoperative iPTH, total mass of parathyroid gland (M) and postoperative iPTH and electrolyte results were collected. The incidence of severe hypocalcemia after TPTX were analyzed retrospectively. Binary logistic regression model was used to analyze the risk factors of severe hypocalcemia after TPTX. Results The age of 783 patients with TPTX was (46.90±10.78) years old, and the average dialysis age was (91.36±41.75) months. Postoperative severe hypocalcemia occurred in 235 cases (30.01％). Binary logistic regression analysis showed that higher preoperative blood iPTH (OR=7.56, 95％CI: 1.55-36.79, P=0.01), higher blood alkaline phosphatase (OR=36.71, 95％CI:14.75-91.36, P<0.01), blood phosphorus (OR=1.74, 95％CI: 1.11-2.71, P=0.02) and greater mass of resected glands (OR=1.18, 95％ CI: 1.06-1.31, P<0.01) were the risk factors for post-hypocalcemia. The higher preoperative serum calcium can reduce the risk of postoperative hypocalcemia (OR=0.02,95％CI: 0.01-0.07, P<0.01). Conclusions The incidence of hypocalcemia after TPTX treatment for SHPT is very high. Blood iPTH, alkaline phosphatase, phosphorus, and total mass of intraoperative parathyroid gland excision are the independent risk factors for severe hypocalcemia after surgery.

Objective: To investigate the incidence and pathogen distribution of ventilator-associated pneumonia (VAP) among preterm infants admitted to level Ⅲ neonatal intensive care units (NICU) in China. Method: A prospective study was conducted in 25 level Ⅲ NICU, enrolling all preterm infants <34 weeks gestational age admitted to the participating NICU within the first 7 days of life from May 2015 to April 2016. Chi-square test, t test and Mann-Whitney U test were used for statistical analysis. Result: A total of 7 918 patients were enrolled, within whom 4 623(58.4%) were males. The birth weight was (1 639±415) g and the gestational age was (31.4±2.0) weeks; 4 654(58.8%) infants required non-invasive mechanical ventilation and 2 154(27.2%) required intubation. Of all the mechanically ventilated patients, VAP occurred in 95 patients. The overall VAP rate was 7.0 episodes per 1 000 ventilator days, varying from 0 to 34.4 episodes per 1 000 ventilator days in different centers. The incidence of VAP was 9.6 and 6.0 per 1 000 ventilator days in children′s hospitals and maternity-infant hospitals respectively, without significant differences (t=1.002, P=0.327). Gram-negative bacilli (76 strains, 91.6%) were the primary VAP microorganisms, mainly Acinetobacter baumannii (24 strains, 28.9%), Klebsiella pneumonia (23 strains, 27.7%), and Pseudomonas aeruginosa (10 strains, 12.0%). Conclusion The incidence of VAP in China is similar to that in developed counties, with substantial variability in different NICU settings. More efforts are needed to monitor and evaluate the preventable factors associated with VAP and conduct interventions that could effectively reduce the occurrence of VAP.

OBJECTIVETo correlate sperm nucleoprotein transition (SNT) with sperm morphology, DNA damage and embryo development, and assess its value for assisted reproductive technology (ART).

METHODSThe SNT of 437 infertile men underwent ART were assayed, and its correlation with sperm morphology, DNA damage, fertilization rate, normal fertilization rate, cleavage rate, available embryo rate, D3 high quality embryo rate, blastocyst formation rate and high quality blastocyst rate were analyzed.

RESULTSThe normal morphology rate of sperms, DNA damage, fertilization rate, normal fertilization rate, cleavage rate, embryo transfer rate (ETR), D3 high quality embryo rate, blastocyst formation rate (BFR) and high quality blastocyst in normal males (Group A, abnormal rate≤30%, 135 subjects) did not significantly differ from those with an abnormal rate between 30% and 60% (Group B, 170 subjects) (P>0.05). For those with an abnormal rate of above 60% (Group C, 132 subjects), the sperm normal morphology rate, DNA damage, normal fertilization rate, ETR, D3 high quality embryo rate, high quality blastocyst rate were significantly lower compared with Group A (P<0.01), while no significant difference was found in fertilization rate, cleavage rate and BFR between groups A and C (P>0.05).

CONCLUSIONSNT is related with sperm morphology rate, DNA damage and embryo development, and should be assessed before ART.
