Objective:To investigate the impact of geniposide(GE)on lung injury in rats with acute respiratory distress syn-drome(ARDS)by regulating AMP-activated protein kinase(AMPK)/silencing information regulator 1(SIRT1)/nuclear factor κB(NF-κB)signaling pathway.Methods:The ARDS rat model was established by tracheal instillation of lipopolysaccharide(LPS).Fifty rats after modeling were randomly group into ARDS group,GE low-dose(GE-L,12.5 mg/kg GE)group,GE medium-dose(GE-M,25 mg/kg GE)group,GE high-dose group(GE-H,50 mg/kg GE)group and GE-H+Compound C(AMPK inhibitor,50 mg/kg GE+250 μg/kg Compound C)group,another 10 normal rats were used as the control group.After the intervention,the bronchoalveolar la-vage fluid(BALF)and lung tissue of the rats in each group were taken out,respectively,and the ratio of lung wet to dry weight(W/D)was detected;ELISA was used to detect the levels of inflammatory factors IL-6,interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α)in BALF;the positive expressions of vascular cell adhesion factor(VCAM-1)and vascular endothelial cell growth factor(VEGF)in lung tissue were detected by immunohistochemistry;HE staining was used to observe the pathological changes of lung tissue;Western blot was used to detect the expression levels of AMPK/SIRT1/NF-κB pathway proteins in lung tissue.Results:The levels of W/D,IFN-γ,IL-6,TNF-α,p-NF-κB p65/NF-κB p65 and VCAM-1 in ARDS group were significantly higher than those in control group,the expressions of p-AMPK/AMPK,SIRT1 and VEGF were significantly decreased(P<0.05);after different doses of GE treatment,the levels of W/D,IFN-γ,IL-6,TNF-α,and the expressions of p-NF-κB p65/NF-κB p65 and VCAM-1 were gradually decreased compared with those in ARDS group;the expressions of p-AMPK/AMPK,SIRT1 and VEGF increased gradually(P<0.05);Compound C reversed the protective effect of GE-H on ARDS rats(P<0.05).Conclusion:GE can improve lung injury in ARDS rats and reduce levels of inflammatory factors,which may be related to activation of AMPK/SIRT1/NF-κB signaling pathway.

Objective To analyze the quality of 19 batches of Ginseng Formula Granules from 11 different manufacturers by using Ginseng water Extract reference substance(GWERS)as references.Methods Thin layer chromatography(TLC)identification and feature map detection were carried out according to the identification items and characteristic maps of Ginseng Formula Granules standard(YBZ-PFKL-2021186)issued by the National Medical Products Administration.Results The results of TLC analysis showed that the 19 batches of Ginseng Formula Granules-labeled samples could be divided into three categories.The overall pattern of the first type of samples was consistent with that of GWERS,and the similarity was high.Pseudoginsenoside F11,a unique component of American ginseng,was detected in the second type of samples.Four blue fluorescent spots were observed in the third type of samples compared to GWERS.HPLC results indicated that all 19 batches of Ginseng Formula Granules showed eight characteristic peaks at the same retention time as that of GWERS chromatogram.Two more chromatographic peaks were found in the chromatogram of three batches of samples from one manufacturer compared to the chromatogram of other samples,whose similarity to the GWERS chromatogram was less than 0.65.The similarity between the chromatogram of the remaining 16 sample and GWERS chromatogram was higher than 0.94.Conclusion At present,the quality of Ginseng Formula Granules on the market varies greatly.It was suspected that American ginseng might appear among them.The application of GWERS for quality analysis of Ginseng Formula Granules has better applicability to the control medicinal materials.

Objective: First-line bevacizumab plus carboplatin and paclitaxel (CP) is approved for stage III/IV ovarian cancer treatment following initial surgical resection, based on global phase III GOG-0218 and ICON7 trials. This study evaluated the efficacy and safety of bevacizumab + CP as first-line ovarian cancer therapy in Chinese patients. Methods: Patients with newly diagnosed, International Federation of Gynecology and Obstetrics (FIGO) stage III/IV epithelial ovarian, fallopian tube, or primary peritoneal cancer post-primary surgery were randomized 1:1 to receive 6 cycles of CP with bevacizumab/ placebo, followed by bevacizumab/placebo maintenance until unacceptable toxicity or disease progression. Primary endpoint was investigator-assessed progression-free survival (PFS). Stratification factors were FIGO stage and debulking status (stage III optimally debulked vs stage III suboptimally debulked vs stage IV) and Eastern Cooperative Oncology Group performance status (0 vs 1 or 2). Results: Of randomized patients, 51 received bevacizumab + CP and 49 received placebo + CP. Median PFS was 22.6 months with bevacizumab + CP (95% confidence interval [CI]=18.6, not estimable) and 12.3 months (95% CI=9.5, 15.0) with placebo + CP (stratified hazard ratio=0.30; 95% CI=0.17, 0.53). Treatment-related grade 3/4 adverse events occurred in 46 of 49 (94%) patients receiving bevacizumab + CP, and 34 of 50 (68%) receiving placebo + CP. Conclusion Bevacizumab + CP showed clinically meaningful improvement in PFS vs placebo + CP, consistent with GOG-0218 results. Safety data were aligned with the known bevacizumab safety profile. These results support first-line bevacizumab + CP therapy in Chinese patients with ovarian cancer.

Objective The objective of this study was to analyze the incidence and mortality of female breast cancer in canc-er registration areas of Gansu province in 2019 and the change trend of female breast cancer incidence and mortality from 2010 to 2019,so as to provide data support for the prevention and treatment of breast cancer.Methods The incidence and mortality data of breast cancer and related demographic data in all cancer registration areas in Gansu province from 2010 to 2019 were collected.The incidence,mortality,age-standardized incidence by Chinese standard population(ASIRC),age-standardized mortality by Chinese standard population(ASMRC),age-standardized incidence by World standard population(ASIRW)and age-standardized mortality by World standard population(ASMRW),cumulative incidence and other key indicators of female breast cancer in each cancer registra-tion area were calculated according to urban and rural distribution and age groups.Joinpoint linear regression was used to analyze the annual change trend of incidence and mortality of female breast cancer in cancer registration areas in Gansu province from 2010 to 2019.Results In 2019,the number of new cases from female breast cancer in the cancer registration areas of Gansu province was 1,502 cases,accounting for 13.14%of all new malignant tumors in women.The incidence was 33.00/100,000,ASIRC and ASIRW were 23.83/100,000 and 23.81/100,000,respectively,and a cumulative rate of 0-74 years old was 2.34%.The incidence of breast cancer in urban and rural areas was 22.25/100,000 and 26.59/100,000,respectively.In 2019,the number of female breast cancer deaths in the cancer registration areas of Gansu province was 254,accounting for 5.61%of all female malignant tumor deaths.The crude mortality was 5.58/100,000,ASMRC and ASMRW were 3.70/100,000 and 3.90/100,000,respectively.The cumulative rate of 0-74 years old was 0.39%.The ASMRC of breast cancer in urban and rural areas was 3.63/100,000 and 3.79/100,000,respec-tively.The annual change trend in the ASIRC of female breast cancer in the province from 2010 to 2019 was not statistically significant(APC=-0.35%,P=0.81),while ASMRC decreased by an average of 9.85%per year(APC=-9.85%,P=0.03).Conclusion Breast cancer is a high incidence malignant tumor that threatens the physical and mental health of female residents in Gansu province,and it is a kind of cancer that women focus on.We should actively screen the risk group of women.

Hearing loss is one of the most common neurosensory disorders in humans,severely affecting pa-tients'quality of life with lack of ideal treatments.Its pathogenesis is related to oxidative stress,inflammation and apoptosis in the inner ear.Recent studies have demonstrated that members of the signal transducer and activator of transcriptions(STATs)family are involved in regulating gene expression in auditory cells during inner ear develop-ment and physiological activities such as apoptosis,oxidative stress,inflammation and autophagy during auditory disorders.In this paper,we review the research on STATs in inner ear development and hearing loss,and elucidate their specific molecular mechanisms,aiming to provide theoretical guidance and direction for the prevention and treatment of hearing loss.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To analyze the impact of patients ages on propofol dosage in painless gastroscopy.Methods A retrospective analysis was conducted on the clinical data of 158 painless gastroscopy patients from January 2017 to June 2020.They were divided into the young group(18～44 years old,n = 57),the middle-aged group(45～59 years old,n = 51),and the elderly group(≥60 years old,n = 50)based on their age.The anesthesia status and safety of each group were compared.Results The results showed that the dosage of propofol,average total dosage of propofol,MAP,HR,RR,SpO2 levels in the young group were higher than those in the middle-aged and elderly groups when consciousness disappeared,and the middle-aged group was higher than the elderly group;The onset time,anesthesia recovery time,orientation recovery time,and departure time in the young group of patients were shorter than those in the middle-aged and elderly groups,and the middle-aged group was shorter than the elderly group(P<0.05).The incidence of airway obstruction,hypoxemia,mandible support,mask ventilation,adverse cardiovascular events,sedation related adverse events,and incidence of obstructed endoscopy in the elderly group were higher than those in the young and middle-aged groups.The incidence of smooth endoscopy was lower than that in the young and middle-aged groups(P<0.05).Conclusion Aging may increase the dosage of propofol in patients underwent painless gastroscopy under anesthesia,prolong the onset time,anesthesia recovery time,orientation recovery time,and departure time,increase stress reactions and adverse reactions,and strengthen monitoring for elderly patients in clinical practice.

Objective To compare the performances of 3D MERGE sequence and 3D SPACE STIR sequence in detecting lumbar disc herniation(LDH).Methods The clinical data and MRI data of 135 LDH patients admitted between January 2020 and November 2022 were analyzed retrospectively.All patients were examined using conventional MRI,3D MERGE sequence and 3D SPACE STIR sequence.The consistency of 3D MERGE sequence and 3D SPACE STIR sequence in measuring the diameter of nerve root was analyzed,and the image quality parameters[signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR)]and image definition score of the two sequences were evaluated.Results There were no statistically significant differences in L3-S1 nerve root diameters measured by 3D MERGE sequence and 3D SPACE STIR sequence(P＞0.05),and the diameters of L3,L4,L5 and S1 measured by the two sequences showed high correlations(r=0.957,0.986,0.975,0.972,P＜0.05).Compared with 3D SPACE STIR sequence,3D MERGE sequence had higher SNR and CNR,scored better on image definition,and displayed nerve root more clearly(P＜0.05).Conclusion 3D MERGE sequence and 3D SPACE STIR sequence have high consistency in the measurement of LDH nerve root diameter.3D MERGE sequence can display the anatomical morphology of nerve root more clearly as compared with 3D SPACE STIR sequence,and the former one has higher image quality.

Objective:To investigate the relationship between oral health and mild cognitive impairment(MCI)by using indicators that evaluate oral hypofunction.Methods:The study was conducted using a cross-sectional design.Participants were recruited from three communities(Shizi Ling, Wenyi Xincun, and Yaoling in Furong District)in Changsha in July 2021, using convenience sampling.Cognitive and oral functions were evaluated using the simple mental state examination, version 2(MMSE-2)and seven indicators of oral hypofunction, which included oral hygiene, oral dryness, occlusal force, tongue and lip movement, tongue pressure, mastication, and swallowing function.Results:A total of 144 subjects were included in this study, with 72 males.Except for education level, there were no statistically significant differences between the MCI group and the normal cognitive group in terms of demographic information and self-reported and measured oral functions(all P>0.05).There was a correlation between the subjects' self-reported oral function and the actual measured oral function.Multiple linear regression analysis revealed no significant correlation between the MMSE score and the seven indicators used to measure oral hypofunction(all P>0.05).The MMSE score of the female group showed a negative correlation with mastication( β=-0.003, P=0.043), while the MMSE score of subjects with elementary school education also showed a negative correlation with mastication( β=-0.022, P=0.016).Additionally, the MMSE score of subjects with middle school education showed a positive correlation with the number of residual teeth( β=0.090, P=0.030). Conclusions:The self-reported oral function can serve as an initial assessment of overall oral function.However, among elderly individuals who do not show significant decline in oral function, there was no significant correlation between oral function and MCI.To accurately identify individuals with MCI, a more detailed sub-analysis with a larger sample size is required.

Objective:To compare the efficacy of pecto-intercostal fascial plane (PIFP) block versus transversus thoracic muscle plane (TTP) block under ultrasound guidance in coronary artery bypass grafting with general anesthesia.Methods:Ninety American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ patients of either sex, aged 50-79 yr, scheduled for elective coronary artery bypass grafting, were divided into 3 groups ( n=30 each) using a random number table method: PIFP block combined with general anesthesia group (PG group), TTP block combined with general anesthesia group (TG group), and general anesthesia group (G group). After anesthesia induction, bilateral PIFP block was performed under ultrasound guidance in group PG, TTP block was performed under ultrasound guidance in group TG. Three groups used the same general anesthesia method and patient-controlled intravenous analgesia after surgery. Visual analog scale scores (cough, position change, etc) at rest and during activity were recorded at 6, 12, 18 and 24 h after operation. The total consumption of intraoperative sufentanil, extubation time, length of stay in intensive care units, rate of rescue analgesia, effective pressing times of patient-controlled analgesia, incidence of postoperative nausea and vomiting, skin pruritus and nerve block-related adverse events were recorded. The operation time of nerve block was recorded and ultrasound-guided needle visibility score was assessed in PG group and TG group. Results:Compared with group G, the total consumption of intraoperative sufentanil was significantly reduced, the extubation time and length of stay in intensive care units were shortened, visual analog scale scores at rest and during activity were decreased at 6, 12 and 18 h after operation, the rate of rescue analgesia was decreased, and the effective pressing times of patient-controlled analgesia were decreased in group PG and group TG ( P<0.05), and no significant change was found in the aforementioned parameters in PG and TG groups ( P> 0.05). Compared with group TG, the operational time of nerve block was significantly shortened, and the ultrasound-guided needle visibility score was increased in group PG ( P<0.05). No nerve block-related adverse events were found in PG and TG groups. There was no significant difference in the incidence of postoperative nausea and vomiting and skin pruritus among the three groups ( P>0.05). Conclusions:PIFP block can provide good perioperative analgesia and promote the rapid recovery in the patients undergoing coronary artery bypass grafting with general anesthesia. Although the analgesic effect of PIFP blockade is similar to that of TTP blockade, PIFP blockade is more clinically valuable due to its simpler operation and less relative risk.
