OBJECTIVE: To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET). METHODS: Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births. RESULTS: Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05). CONCLUSIONS Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

Objective:To study the clinical characteristics of congenital esophageal atresia (CEA) and risk factors of mortality associated with esophageal repair (ER) surgery.Methods:From January 2010 to December 2022, patients diagnosed of CEA using chest and abdomen X-ray and esophagography in our hospital were retrospectively reviewed. The patients were assigned into ER group and non-ER group according to the treatments. The ER group was subgrouped into survival group and death group according to the prognosis. Clinical data and outcomes were collected and compared between the groups.Results:A total of 553 cases were enrolled. According to Gross classification, 29 patients (5.2%) were type A, 2 patients (0.4%) were type B, 504 patients (91.1%) were type C, 6 patients (1.1%) were type D and 11 patients (2.0%) were type E. One patient had simple transluminal septal atresia of the esophagus. 406 patients were in ER group and 147 in non-ER group. Compared with ER group, non-ER group had significantly higher incidences of preterm birth, low birth weight and overall malformations (all P<0.05). In ER group, 152 patients (37.4%) received open thoracic surgery (OTS), 243 (59.9%) had video-assisted thoracoscopic surgery (VATS) and 11 (2.7%) were VATS converted to OTS. Postoperative anastomotic leakage (PAL) occurred in 92 patients (22.7%) and 15 patients (3.7%) died after surgery. The median length of hospital stay was 23 (17, 36) d. Compared with the survival group, the death group had higher incidences of preterm birth, low birth weight, VATS converted to OTS, mechanical ventilation after ER, and shorter length of hospital stay (all P<0.05). After adjusted for birth weight, VATS converted to OTS ( OR=9.585, 95% CI 1.899-48.374) and mechanical ventilation after ER ( OR=7.821, 95% CI 1.002-61.057) were risk factors of mortality in ER patients. Conclusions:Non-ER patients have higher incidences of preterm birth, low birth weight and overall malformations than ER patients. VATS is the method of choice for CEA. Preterm birth, low birth weight, VATS converted to OTS and mechanical ventilation after ER are risk factors of mortality in ER patients.

Bacterial biofilms gave rise to persistent infections and multi-organ failure, thereby posing a serious threat to human health. Biofilms were formed by cross-linking of hydrophobic extracellular polymeric substances (EPS), such as proteins, polysaccharides, and eDNA, which were synthesized by bacteria themselves after adhesion and colonization on biological surfaces. They had the characteristics of dense structure, high adhesiveness and low drug permeability, and had been found in many human organs or tissues, such as the brain, heart, liver, spleen, lungs, kidneys, gastrointestinal tract, and skeleton. By releasing pro-inflammatory bacterial metabolites including endotoxins, exotoxins and interleukin, biofilms stimulated the body’s immune system to secrete inflammatory factors. These factors triggered local inflammation and chronic infections. Those were the key reason for the failure of traditional clinical drug therapy for infectious diseases.In order to cope with the increasingly severe drug-resistant infections, it was urgent to develop new therapeutic strategies for bacterial-biofilm eradication and anti-bacterial infections. Based on the nanoscale structure and biocompatible activity, nanobiomaterials had the advantages of specific targeting, intelligent delivery, high drug loading and low toxicity, which could realize efficient intervention and precise treatment of drug-resistant bacterial biofilms. This paper highlighted multiple strategies of biofilms eradication based on nanobiomaterials. For example, nanobiomaterials combined with EPS degrading enzymes could be used for targeted hydrolysis of bacterial biofilms, and effectively increased the drug enrichment within biofilms. By loading quorum sensing inhibitors, nanotechnology was also an effective strategy for eradicating bacterial biofilms and recovering the infectious symptoms. Nanobiomaterials could intervene the bacterial metabolism and break the bacterial survival homeostasis by blocking the uptake of nutrients. Moreover, energy-driven micro-nano robotics had shown excellent performance in active delivery and biofilm eradication. Micro-nano robots could penetrate physiological barriers by exogenous or endogenous driving modes such as by biological or chemical methods, ultrasound, and magnetic field, and deliver drugs to the infection sites accurately. Achieving this using conventional drugs was difficult. Overall, the paper described the biological properties and drug-resistant molecular mechanisms of bacterial biofilms, and highlighted therapeutic strategies from different perspectives by nanobiomaterials, such as dispersing bacterial mature biofilms, blocking quorum sensing, inhibiting bacterial metabolism, and energy driving penetration. In addition, we presented the key challenges still faced by nanobiomaterials in combating bacterial biofilm infections. Firstly, the dense structure of EPS caused biofilms spatial heterogeneity and metabolic heterogeneity, which created exacting requirements for the design, construction and preparation process of nanobiomaterials. Secondly, biofilm disruption carried the risk of spread and infection the pathogenic bacteria, which might lead to other infections. Finally, we emphasized the role of nanobiomaterials in the development trends and translational prospects in biofilm treatment.

Objective To analyze the therapeutic effects and survival benefits of sintilimab combined with albumin-bound paclitaxel chemotherapy in the treatment of patients with advanced gastric cancer.Methods Patients with advanced gastric cancer were divided into the treatment group and the control group by cohort method.The control group was treated with albumin-bound paclitaxel-based chemotherapy[intravenous infusion of albumin-bound paclitaxel at 125 mg·m-2 from day 1 to day 8,for a cycle(21 days as a cycle);Tiggio capsule 40 mg·m-2·d-1 was taken orally for 1-14 days for 1 consecutive cycle;Trastuzumab was administered once every 3 weeks at an initial loading dose of 8 mg·kg-1,followed by maintenance treatment at a dose of 6 mg·kg-1 every 3 weeks].On this basis,the treatment group was treated with intravenous infusion of sintilimab injection at a dose of 200 mg·time-1 on the first day of each cycle,with 21 d as a cycle.After 6 cycles of continuous treatment,both groups were given maintenance treatment and were followed up for 8 months.The two groups were compared in terms of clinical efficacy,the levels of serum tumor markers[carbohydrate antigen 242(CA242),carbohydrate antigen 724(CA724),carcinoembryonic antigen(CEA),tissue polypeptide-specific antigen(TPS),soluble intercellular cell adhesion molecule-1(sICAM-1)and E-cadherin],survival and evaluated the safety.Results In this study,39 and 41 patients were enrolled in the control group and the treatment group,respectively.At the end of treatment,the objective response rates(ORR)in the treatment group and the control group were 56.10％and 33.33％;the disease control rates(DCR)were 78.05％and 48.71％.The differences were statistically significant(all P＜0.05).After treatment,serum CA242 levels in the treatment group and the control group were(57.64±5.82)and(68.95±7.23)mg·L-1;CA724 levels were(36.58±3.79)and(43.65±4.48)U·mL-1;CEA levels were(17.33±1.78)and(20.16±2.35)ng·mL-1;TPS levels were(21.35±2.44)and(37.65±3.84)U·L-1;sICAM-1 levels were(216.77±22.53)and(275.34±28.63)ng·mL-1;E-cadherin levels were(12.15±1.36)and(9.87±1.45)ng·mL-1.The differences were statistically significant(all P＜0.05).The average progression free survival(PFS)of the treatment group and the control group was 7.55 months and 7.17 months;PFS rates were 65.78％and 56.42％.The differences were statistically significant(P＜0.05).The adverse drug reactions in the treatment group and the control group were mainly bone marrow suppression,nausea and vomiting,liver function damage,peripheral nerve paresthesia,and hypothyroidism.There was no statistically significant difference in the above adverse drug reactions between the treatment group and the control group(all P＞0.05).Conclusion Sintilimab combined with albumin-bound paclitaxel chemotherapy is effective in the treatment of patients with advanced gastric cancer,which can significantly improve serum tumor markers and prolong PFS,with good safety.

The aim of this study was to investigate and evaluate the antitumor effects of a novel poly(ADP-ribose) polymerase (PARP) 1/2 inhibitor, YHP-836, in combination with temozolomide (TMZ) for the treatment of glioblastoma (GBM). The cytotoxicity of YHP-836 was tested alone or in combination with TMZ using MTT assay. Immunoblotting and flow cytometry were also employed to assess the combination activity of YHP-836 and TMZ in multiply GBM cell lines. Further, the antitumor activity of YHP-836 and TMZ was evaluated using subcutaneous and orthotopic mice xenograft tumor models. All procedures were approved by the Ethics Committee for Animal Experiments of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College and conducted under the Guidelines for Animal Experiments of Peking Union Medical College. The approval number is 00009138. It was demonstrated that the combination of YHP-836 and TMZ increased the cytotoxicity against GBM cells and upregulated histone H2AX phosphorylation (γH2AX) expression levels compared to TMZ treatment alone. The combination also led to the S-phase cell cycle arrest. Moreover, YHP-836 significantly enhanced TMZ antitumor effects without significantly increasing chemotherapy drug toxicity in vivo, whereas YHP-836 alone showed limited therapeutic efficacy against GBM. In conclusion, the novel PARP1/2 inhibitor, YHP-836, sensitizes TMZ and provides a basis for further investigation into its mechanism of action. These findings suggest that YHP-836 may be a potential candidate for combination therapy with TMZ in patients with TMZ resistance.

Objective: To identify the main metals involved in cognitive impairment in the Chinese oldest old, and explore the association between these metal exposures and cognitive impairment. Methods: A cross-sectional study was conducted on 1 568 participants aged 80 years and older from Healthy Aging and Biomarkers Cohort Study (2017 to 2018). Fasting venous blood was collected to measure the levels of nine metals (selenium, lead, cadmium, arsenic, antimony, chromium, manganese, mercury, and nickel). The cognitive function of these participants was evaluated by using the Chinese version of the Mini-Mental State Examination (CMMSE). The random forest (RF) was applied to independently identify the main metals that affected cognitive impairment. The multivariate logistic regression model and restricted cubic splines (RCS) model were used to further verify the association of the main metals with cognitive impairment. Results: The age of 1 568 study subjects was (91.8±7.6) years old, including 912 females (58.2%) and 465 individuals (29.7%) with cognitive function impairment. Based on the RF model (the out-of-bag error rate was 22.9%), the importance ranking of variables was conducted and the feature screening of five times ten-fold cross-validation was carried out. It was found that selenium was the metal that affected cognitive function impairment, and the other eight metals were not included in the model. After adjusting for covariates, the multivariate logistic regression model showed that with every increase of 10 μg/L of blood selenium levels, the risk of cognitive impairment decreased (OR=0.921, 95%CI: 0.889-0.954). Compared with the lowest quartile(Q₁) of blood selenium, the ORs (95%CI) of Q₃ and Q₄ blood selenium were 0.452 (0.304-0.669) and 0.419 (0.281-0.622) respectively. The RCS showed a linear dose-response relationship between blood selenium and cognitive impairment (P_nonlinear>0.05). Conclusion: Blood selenium is negatively associated with cognitive impairment in the Chinese oldest old.

Objective: To analyze the global epidemiology of renal cell carcinoma (RCC) in 2020. Methods: The incidence and mortality data of RCC in the cooperative database GLOBOCAN 2020 of International Agency for Research on Cancer of WHO and the human development index (HDI) published by the United Nations Development Programme in 2020 were collated. The crude incidence rate (CIR), age-standardized incidence rate (ASIR), crude mortality rate (CMR), age-standardized mortality rate (ASMR) and mortality/incidence ratio (M/I) of RCC were calculated. Kruskale-Wallis test was used to analyze the differences in ASIR or ASMR among HDI countries. Results: In 2020, the global ASIR of RCC was 4.6/100 000, of which 6.1/100 000 for males and 3.2/100 000 for females and ASIR was higher in very high and high HDI countries than that in medium and low HDI countries. With the rapid increase of age after the age of 20, the growth rate of ASIR in males was faster than that in females, and slowed down at the age of 70 to 75. The truncation incidence rate of 35-64 years old was 7.5/100 000 and the cumulative incidence risk of 0-74 years old was 0.52%. The global ASMR of RCC was 1.8/100 000, 2.5/100 000 for males and 1.2/100 000 for females. The ASMR of males in very high and high HDI countries (2.4/100 000-3.7/100 000) was about twice that of males (1.1/100 000-1.4/100 000) in medium and low HDI countries, while the ASMR of female (0.6/100 000-1.5/100 000) did not show significant difference. ASMR continued to increase rapidly with age after the age of 40, and the growth rate of males was faster than that of females. The truncation mortality rate of 35-64 years old was 2.1/100 000, and the cumulative mortality risk of 0-74 years old was 0.20%. M/I decreases with the increase of HDI, with M/I as 0.58 in China, which was higher than the global average of 0.39 and the United States' 0.17. Conclusion: The ASIR and ASMR of RCC presented significant regional and gender disparities globally, and the heaviest burden was in very high HDI countries.

Extensive research supported the therapeutic potential of curcumin, a naturally occurring compound, as a promising cytokinesuppressive anti-inflammatory drug. This study aimed to investigate the synergistic anti-inflammatory and anti-cytokine activities by combining 6-shogaol and 10-shogaol to curcumin, and associated mechanisms in modulating lipopolysaccharides and interferon-ɣ-induced proinflammatory signaling pathways. Our results showed that the combination of 6-shogaol-10-shogaol-curcumin synergistically reduced the production of nitric oxide, inducible nitric oxide synthase, tumor necrosis factor and interlukin-6 in lipopolysaccharides and interferon-γ-induced RAW 264.7 and THP-1 cells assessed by the combination index model. 6-shogaol-10-shogaol-curcumin also showed greater inhibition of cytokine profiling compared to that of 6-shogaol-10-shogaol or curcumin alone. The synergistic anti-inflammatory activity was associated with supressed NFκB translocation and downregulated TLR4-TRAF6-MAPK signaling pathway. In addition, SC also inhibited microRNA-155 expression which may be relevant to the inhibited NFκB translocation. Although 6-shogaol-10-shogaol-curcumin synergistically increased Nrf2 activity, the anti-inflammatory mechanism appeared to be independent from the induction of Nrf2. 6-shogaol-10-shogaol-curcumin provides a more potent therapeutic agent than curcumin alone in synergistically inhibiting lipopolysaccharides and interferon-γ induced proinflammatory mediators and cytokine array in macrophages. The action was mediated by the downregulation of TLR4/TRAF6/MAPK pathway and NFκB translocation.
