OBJECTIVE To investigate the establishment and promotion of a new standardized management model for anti- osteoporosis medication after fragility fracture surgery by resident clinical pharmacists， and provide references for resident pharmacists to carry out clinical pharmaceutical services. METHODS From July 2023 to March 2024，595 post-brittle fracture surgery patients were enrolled. Using the PDCA （plan-do-check-act） cycle，resident clinical pharmacists identified issues and conducted investigations in clinical practice. Through integrating clinical pharmacist intervention services before， during and after treatment， a medication treatment pathway was developed， thereby establishing a standardized management model for anti- osteoporosis treatment following fragility fracture surgery. Leveraging the National Brittle Fracture Big Data Platform （under the National Clinical Research Center for Orthopedics and Sports Rehabilitation）， a dedicated data module was constructed， providing big data support to evaluate the efficacy of this pharmaceutical care model. RESULTS Continuous PDCA cycle driven improvements significantly increased the proportion of osteoporosis diagnosis （from 9% before intervention to 81%） and proportion of drug treatment （from 4% to 75%）.The proportions of bone density and bone metabolism testing also rose markedly，positively impacting long-term patient outcomes. CONCLUSIONS The establishment of a standardized management model for anti- osteoporosis treatment following fragility fracture surgery by resident clinical pharmacists has enhanced clinicians’ diagnostic and therapeutic capabilities for osteoporosis， ensures rational medication use in osteoporosis patients， and demonstrates significant potential for widespread adoption and application.

Objective:To investigate the repair effect of bone marrow mesenchymal stem cells(BMSCs)on interferon gamma(IFN-γ)induced ovarian granulosa cell immune injury.Methods:A model of IFN-γ-induced ovarian granulosa cell immune injury was estab-lished.KGN cells after modeling were co-cultured with human BMSCs(hBMSCs)and divided into three groups:negative control(NC)group,IFN-γ group,and BMSC group.After co-culture,cell proliferation was determined by a cell counting kit 8 assay for 3 consecu-tive days.Cell apoptosis was determined using an Annexin V-FITC apoptosis detection kit and a CytoFLEX flow cytometer.The estra-diol level and the mRNA expression levels of aromatase CYP19A1 and FSHR were measured to evaluate the hormone synthesis ability.The level of lactate dehydrogenase(LDH),mRNA expression levels of NLRP3,caspase-1(CASP1),and interleukin-1β,and protein expression levels of NLRP3,CASP1,and gasdermin-D were determined to evaluate cell pyroptosis.Results:The proliferation rate of granulosa cells in the IFN-γ group and the BMSC group was lower than that in the NC group at 24 h,48 h and 72 h,and that in the IFN-γ group was lower than that in the BMSC group(P<0.001).The number of apoptotic granulosa cells in the INF-γ group and the BMSC group was higher than that in the NC group,and that in the INF-γ group was higher than that in the BMSC group(P<0.001).The estradiol level in the INF-γ group and the BMSC group was lower than that in the NC group,and that in the INF-γ group was lower than that in the BMSC group(P<0.001).Compared with the IFN-γ group,the mRNA expression of CYP19A1 and FSHR in the BMSC group decreased(P<0.001).Compared with the IFN-γ group,the BMSC group had significantly decreased LDH level,mRNA expression levels of NLRP3 and CASP1,and protein expres-sion level of CASP1.Conclusion:hBMSCs repair the immune in-jury of KGN cells induced by IFN-γ by restoring cell proliferation,inhibiting cell apoptosis,repairing endocrine function,and reducing pyroptosis.

Tracheostomy is a very common airway procedure in the treatment of critically ill neurological patients. At present, the traditional tracheal cannula fixation belt is easy to be contaminated, difficult to disinfect, and needs to be replaced regularly. It is prone to infection, skin injury, unplanned extubation and other adverse events, which cannot meet the clinical treatment effect and patient safety management. In order to overcome the above problems, the medical staff of the neurology intensive care unit of Henan Provincial People's Hospital designed a new type of tracheal cannula fixation belt to increase patient comfort and reduce complications, and obtained a National Utility Model Patent of China (ZL 2022 2 0855188.8). The main structure of the device includes a following shaped bending plate, a fastening belt, a locking pin, and a distance adjustment hole. The left and right sides of the shaped bending plate are equipped with fastening belts with breathable and anti-wear pads. The inner side of the left fastening belt is equipped with two sets of locking pins, and the outer surface of the right fastening belt and breathable and anti-wear pad is equipped with multiple sets of distance adjustment holes. Additionally, the back of the shaped bending plate is equipped with breathable buffer pads. The fastening belt can drive the following bending plate to stick tightly to the patient's neck. The operator installs the locking pin card into the distance adjustment hole according to the "one back" principle, and the fastening belts on both sides fix the device with the cooperation of the locking pin, greatly reducing the probability of excessive displacement of the tracheal tube during use, effectively improving the fixation effect of the device, strengthening the adaptability of the device to different personnel, and thus enhancing the practicality of the device. The new type of tracheal cannula fixation band is convenient, safe and efficient, which can increase patient comfort, reduce complications. It has certain clinical value and is suitable for clinical promotion.

Objective To compare the effects of the left and right stellate ganglion resection on myocardial injury in rats with acute myocardial infarction(AMI).Methods According to the random number table method,30 healthy male Sprague Dawley rats were divided into the AMI group,left stellate ganglionectomy group,and right stellate ganglionectomy group,with 10 rats in each group.AMI models were prepared by ligation of the left anterior descending branch of the coronary artery in all the three groups.In the AMI group,the stellate ganglion was isolated(randomly left or right)without excision.The rats in the left and right stellate ganglionectomy groups underwent the left and right stellate ganglionectomy,respectively.At 24 hours after modeling,2 mL of subclavian venous blood was extracted from the three groups of rats.The serum levels of cardiac troponin Ⅰ(cTnⅠ),noradrenaline(NE),interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α),malondialdehyde(MDA),and superoxide dismutase(SOD)were detected by enzyme-linked immunosorbent assay.The left ventricular fractional shortening(LVFS),left ventricular ejection fraction(LVEF)and cardiac output(CO)of rats in the three groups were measured by echocardiography one week after modeling.Results The serum levels of NE,cTnⅠ and MDA in the left and right stellate ganglionectomy groups were significantly lower than those in the AMI group,and SOD level was significantly higher than that in the AMI group(P＜0.05);the serum levels of NE,cTnⅠ and MDA in the right stellate ganglionectomy group were significantly lower than those in the left stellate ganglionectomy group,and SOD level was significantly higher than that in the left stellate ganglionectomy group(P＜0.05).The levels of serum IL-1β,IL-6 and TNF-α in the left and right stellate ganglionectomy groups were significantly lower than those in the AMI group(P＜0.05);the levels of serum IL-1β,IL-6 and TNF-αin the right stellate ganglionectomy group were significantly lower than those in the left stellate ganglionectomy group(P＜0.05).LVEF,LVFS and CO in the left and right stellate ganglionectomy groups were significantly higher than those in the AMI group,and LVEF and LVFS in the right stellate ganglionectomy group were significantly higher than those in the left stellate ganglionectomy group(P＜0.05);there was no significant difference in CO between the left and right stellate ganglionectomy groups(P＞0.05).Conclusion Stellate ganglionectomy has a protective effect on AMI induced by ligation of the left anterior descending branch of the coronary artery,which may be related to reducing inflammatory reaction and oxidative stress damage.The right stellate ganglion resection has more protective effects on cardiac function than the left stellate ganglion resection.

Objective:To analyze the problems existing in the cases of hospitals infringing upon patients′ informed consent right after the promulgation of the Civil Code of the People′ s Republic of China, and to provide reference for improving the legal system of informed consent. Methods:Search for judgment documents published from January 1, 2021 to June 30, 2023 on the China Judgment Document Network using the keyword " liability dispute for infringing on patients′ informed consent rights", and conduct descriptive and textual analysis on the cases in the judgment documents.Results:68 judgment documents were included in total.There were 11 judgment documents on infringement of patients′ right to informed consent, and all related cases have undergone appraisal. The content of infringement mainly included infringement of patients′ right to know their condition (12/20), infringement of patients′ right to access their medical records (6/20), infringement of patients′ right to bodily integrity without consent (2/20). There were 15 judgment documents which judge that the right of informed consent of patients wasn′t infringed, and only one case in the document has been appraised. The main focus of controversy was the issue of the priority of the exercise of the right to informed consent (2/15), the fulfillment of the obligation to inform the right to informed consent (5/15), the issue of surgery without notification (1/15), and the issue of determining the authenticity of medical records and providing medical materials (7/15).Conclusions:The legal protection of patients′ right to informed consent still faces judicial difficulties such as unclear order of the exercise of rights subject, insufficient specificity of the scope of the exercise of the right, conflicts between the right to informed consent and medical intervention, and lack of unified identification methods for infringement liability. It is suggested to standardize the order of the exercise subject of the right to informed consent, clarify the content of the obligation of the medical party to inform, construct a system for medical intervention, and unify the identification methods for disputes related to the right to informed consent.

Objective To investigate ecological isolation between Oncomelania hupensis snail populations in hilly regions and marshland and lake regions in Yuanjiang valley, Changde City, Hunan Province, and to unravel its underlying mechanisms. Methods Taoyuan County, Shimen County, Linli County and Lixian County in Changde City were selected as snail sampling sites in hilly regions, and Lixian County, Jinshi City, West Lake Administration District, Hanshou County and Dingcheng District were selected as snail sampling sites in marshland and lake areas. Cytochrome C oxidase 1 (cox 1) gene was amplified in snail samples and sequenced. The genetic sequences of O. hupensis snails were aligned using the software MEGA 11, and the haplotypes of O. hupensis snails were determined using the software DNASP 5.10.01. The phylogenetic tree was generated using Bayesian inference with the software MrBayes 3.2, and analysis of molecular variance (AMOVA) was performed to analyze the source of genetic divergence and estimate the genetic divergence index (F_ST) among snail populations with the software Arlequin 3.5.2.2. The genetic barrier among 11 O. hupensis snail populations was estimated using the Monmonier algorithm of adegenet toolkit in R package. The settings with “land in winter and water in summer” in the Yuanjian River section were divided into two categories according to the upstream and downstream, and the areas with “land in winter and water in summer” in the upstream and downstream were transformed into raster data, and then loaded into the software Fragstats 4 for analysis of landscape indicators. The trends in changes of digital elevation were extracted from the Yuanjiang River section based on the digital elevation model, and made three-dimensional visualization using the R package. Results The mitochondrial cox 1 gene were amplified in 165 O. hupensis snais from 11 sampling sites and sequenced, and a total of 152 valid gene sequences were obtained, with 46 haplotypes or 9 populations determined. No haplotype was shared in snails between Taoyuan County and Dingcheng District and Hanshou County along the downstream of the Yuanjiang River. The total area of settings with “land in winter and water in summer” was 617.66 hm² in the upsteram of the Yuanjiang River, which consisted of 473 patches, with each patch measuring 1.31 hm², the largest area index of 0.735 2, the landscape division index of 0.999 9, and the landscape shape index of 45.293 7. The total area of settings with “land in winter and water in summer” was 9 956.92 hm² in the downstream of the Yuanjiang River, which consisted of 771 patches, with each patch measuring 12.91 hm², the largest area index of 97.839 9, the landscape division index of 0.042 7, and the landscape shape index of 7.249 6. The area of settings with “land in winter and water in summer” was much larger in the downstream than that in the upstream of the Yuanjiang River, and the stronger landscape connectivity and non-remarkable alteration of riverbed elevation provided suitable habitats for snail breeding. Conclusion The hydrological and environmental characteristics of the upstream of the Yuanjiang River restrain the breeding and spread of O. hupensis, resulting in ecological isolation between Oncomelania hupensis in Taoyuan County and those in the downstream of Yuanjiang River.

Objective:To evaluate the effect of superior cervical ganglion block (SCGB) on cardiac function and nucleotide like receptor protein 3 (NLRP3) signaling pathway in a rat model of myocardial ischemia-reperfusion (I/R).Methods:Sixty healthy SPF male Sprague-Dawley rats, weighing 250-300 g, aged 2-3 months, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (sham group), myocardial I/R group (IR group), myocardial I/R + normal saline group (IR+ NS group), and myocardial I/R + SCGB group (IR+ SCGB group). Myocardial I/R model was developed by ligation of the left anterior descending branch of the coronary artery for 45 min followed by restoration of blood flow in anesthetized aninals. IR+ SCGB group received SCGB (0.25% ropivacaine 0.1 ml) at 10 min before reperfusion once a day for 2 consecutive weeks, while 0.9% sodium chloride was given instead of ropivacaine in IR+ NS group. Blood samples were collected at 24 h and 14 days of reperfusion for determination of serum concentrations of norepinephrine (NE), troponin T (TnT), tumor necrosis factor-alpha (TNF-α), interleukin-18 (IL-18) and IL-1β by enzyme-linked immunosorbent assay. Echocardiography was performed before ischemia and at 14 days of reperfusion, and left ventricular short axis shortening rate (FS), ejection fraction (EF), and cardiac output (CO) were measured. The rats were sacrificed at 14 days of reperfusion and the hearts were taken for determination of the contents of norepinephrine (NE) in myocardial tissues in the infarction area (by enzyme-linked immunosorbent assay), percentage of myocardial fibrosis area (by Masson staining), M1 macrophage marker CD68 + cell count in the infarction area (by immunohistochemical method), and expression of NLRP3 and gasdermin D (GSDMD) in myocardial tissues (by Western blot). Results:Compared with Sham group, the serum concentrations of TnT, TNF-α, IL-18 and IL-1β, percentage of myocardial fibrosis area, and NE levels in serum and myocardial tissues were significantly increased, the expression of NLRP3 and GSDMD in myocardial tissues was up-regulated, CD68 + cell count was increased, and EF, CO and FS were decreased in IR group ( P<0.05). Compared with IR group, the serum concentrations of TnT, TNF-α, IL-18 and IL-1β, percentage of myocardial fibrosis area, and NE levels in serum and myocardial tissues were significantly decreased, the expression of NLRP3 and GSDMD in myocardial tissues was down-regulated, CD68 + cell count was decreased, and EF, CO and FS were increased in IR+ SCGB group ( P<0.05), and no statistically significant changes were found in the parameters mentioned above in IR+ NS group ( P>0.05). Conclusions:SCGB can improve the cardiac function in a rat model of myocardial I/R, and the mechanism may be related to the inhibition of NLRP3 signaling pathway.
