OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance （shorted for “medical alliance”） of Wanzhou District of Chongqing， and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units （5 leading units and 16 member units） of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use， pharmaceutical personnel team construction， the development of pharmaceutical care， and rational use of antibiotics. RESULTS Among the 21 constituent units， 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties， with a total compliance rate of 85.71%； 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount， with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively， and the proportions of personnel with senior professional titles were 8.56% and 1.63%， respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units， and 5 clinical pharmacy information service platforms were established； all 5 leading units were able to regularly carry out clinical pharmacy projects， while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units （4.81%， 5.21%） were significantly higher than those of the 5 leading units （2.80%， 4.00%）. CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However， the data on the allocation of pharmaceutical professionals and the number， qualifications， and job titles of clinical pharmacists in member units are generally low. Moreover， the pharmaceutical service projects and service quality in member units need to be further improved.

Lenvatinib, a second-generation multi-receptor tyrosine kinase inhibitor approved by the FDA for first-line treatment of advanced liver cancer, facing limitations due to drug resistance. Here, we applied a multidimensional, high-throughput screening platform comprising patient-derived resistant liver tumor cells (PDCs), organoids (PDOs), and xenografts (PDXs) to identify drug susceptibilities for conquering lenvatinib resistance in clinically relevant settings. Expansion and passaging of PDCs and PDOs from resistant patient liver tumors retained functional fidelity to lenvatinib treatment, expediting drug repurposing screens. Pharmacological screening identified romidepsin, YM155, apitolisib, NVP-TAE684 and dasatinib as potential antitumor agents in lenvatinib-resistant PDC and PDO models. Notably, romidepsin treatment enhanced antitumor response in syngeneic mouse models by triggering immunogenic tumor cell death and blocking the EGFR signaling pathway. A combination of romidepsin and immunotherapy achieved robust and synergistic antitumor effects against lenvatinib resistance in humanized immunocompetent PDX models. Collectively, our findings suggest that patient-derived liver cancer models effectively recapitulate lenvatinib resistance observed in clinical settings and expedite drug discovery for advanced liver cancer, providing a feasible multidimensional platform for personalized medicine.

Objective:To study the clinical manifestations, genetic profiles and treatment of Kagami-Ogata syndrome (KOS).Methods:A neonate admitted to our hospital was genetically diagnosed of KOS from amniocentesis sampling. The phenotype, genotype and treatment of the neonate were analyzed. Multiple databases were searched using key words including "Kagami-Ogata syndrome", "14q32 microdeletion syndrome", "coat-hanger ribs", "paternal uniparental disomy (pUPD)(14) " from the inception of the databases to Jan. 23th 2023. The clinical features, genotype and treatment of patients from the literature were summarized.Results:The neonate in our hospital was born at 30 weeks gestational age with a birth weight of 2 035 g. Prenatal ultrasound indicated overgrowth, bilateral fetal renal pelvis dilatation (FRPD), dilatation of intestines in lower abdomen, clenched hands with overlapping fingers and polyhydramnios. After birth, the neonate showed progressively worsening respiratory distress, distinct facial features (small jaw, short neck, flat nasal bridge, upward-facing nostrils, small and malformed ears with auricular deformity and narrow external auditory canals), bell-shaped thorax, diastasis recti and abnormal posture (overlapping fingers, clenched fists), as well as feeding difficulties, recurrent fever and dependence of respiratory support. Whole exome sequencing (WES) revealed a 268.2Kb deletion (101034306_101302541) in 14q32.2 region on both the neonate and the mother and the father was otherwise normal. The prognosis was poor and the parents refused further treatment. The neonate died at one month of age after two days of palliative care. A total of 36 articles were identified in the literature review, including 78 KOS cases with complete clinical data (a total of 79 cases adding our case).The primary clinical manifestations included distinctive facial and thoracic abnormalities (79/79, 100%), polyhydramnios (71/75, 94.7%), feeding difficulties (55/63, 87.3%), abdominal wall defects (57/72, 79.2%), joint contractures (39/70, 55.7%) and dependence of respiratory support (29/56, 51.8%). Long-term follow-up revealed 86.8% (59/68) experienced physical, movement and intellectual development delay, 39.7% (25/63) died or gave up treatments within five years. Genetic testing showed pUPD in 44 cases (55.7%), maternal deletions in 23 cases (29.1%), epimutations in 8 cases (10.1%) and unreported variations in 4 cases (5.1%).Conclusions:KOS is a genetic imprinting disorder affecting multiple organs. Prenatal screening can detect abnormalities such as polyhydramnios. Specific clinical signs, radiological findings and 14q32 gene analysis are helpful for the diagnosis of the disease.

Objective:To study influence of cardiac rehabilitation exercise combined nutritional intervention on pa-tients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods:A total of 100 AMI patients treated in our hospital were randomly and equally divided into routine nursing group and combined intervention group(received cardiac rehabilitation exercise combined nutritional intervention mode based on routine nursing group)according to random number table method.Both groups were intervened for two months.General clinical data,anaerobic threshold(AT),maximal oxygen uptake(VO2peak),LVEF,6min walking distance(6MWD),scores of China questionnaire of quality of life in patients with cardiovascular diseases(CQQC)and gen-eral self-efficacy scale(GSES)before and after intervention and incidence rate of cardiovascular adverse events within three months were compared between two groups.Results:Compared with routine nursing group,after inter-vention,there were significant rise in AT[(10.14±2.81)ml·kg-1·min-1 vs.(14.85±3.80)ml·kg-1· min-1],VO2peak[(1.23±0.40)ml·kg-1·min-1 vs.(2.44±0.46)ml·kg-1·min-1],LVEF[(48.96± 3.73)％vs.(55.98±4.31)％],6MWD[(300.72±33.71)m vs.(340.47±31.86)m],scores of CQQC[(53.59 ±6.28)scores vs.(72.93±7.15)scores]and GSES[(21.21±2.39)scores vs.(32.28±5.44)scores]in com-bined intervention group(P=0.001 all).Incidence rate of cardiovascular adverse events in combine intervention group within three months was significantly lower than that of routine nursing group(10.0％vs.48.0％,P=0.001).Conclusion:Cardiac rehabilitation exercise combined nutritional intervention can observably improve quality of life,cardiopulmonary function,enhance self-efficacy and reduce incidence rate of adverse cardiovascular events in patients with acute myocardial infarction after percutaneous coronary intervention.

Objective To observe the effect of electroacupuncture on corneal Toll-like receptor 4(TLR4)-mediated inflammatory signaling pathway in diabetic dry eye rats and to explore the mechanism of electroacupuncture in the treat-ment of diabetic dry eye.Methods A type 2 diabetic rat model was established in 32 healthy male Sprague-Dawley(SD)rats by intraperitoneal injection of streptozotocin(30 mg·kg-1)for 12 weeks after feeding with high-sugar and high-fat di-et for 4 weeks.Twenty-five successfully modeled diabetic dry eye rats were randomly divided into the model group(non-in-tervention),electroacupuncture group(the"Jingming","Cuanzhu","Sizhukong","Taiyang"and"Tongziliao"acupoints were treated with acupuncture,and then"Cuanzhu"and"Tongzilao"acupoints were treated with electroacupuncture,15 min for each time,once a day),sham acupuncture group(blunt-tip needle pricking was performed at the same acupoints as the electroacupuncture group),and fluorometholone group(1 g·L-1fluorometholone eye drops were used in both eyes at 8 o'clock,13 o'clock,and 18 o'clock,1 drop each time),with 6 rats in each group,lasting for 2 weeks.Another 6 healthy male SD rats were selected as a blank group.Random blood glucose,tear film breakup time(BUT),tear secre-tion,corneal fluorescein staining(FL)score,and corneal touch threshold(CTT)of rats in each group were detected be-fore modeling,after modeling,and after the intervention.Hematoxylin and Eosin(HE)staining was performed to observe the corneal morphologic changes in each group.Immunofluorescence histochemical staining was adopted to detect the cor-neal TLR4-positive expression in each group.The TLR4,phosphorylated nuclear factor-kappa P65(P-NF-KB P65),inter-leukin(IL)-1β,and IL-18 expression levels in the cornea were detected by Western blot.Results After modeling,com-pared with the blank group,BUT,tear secretion and CTT decreased and FL increased in all experimental groups,and the differences were statistically significant(all P＜0.01).After the intervention,compared with the model group,FL de-creased,and BUT,tear secretion and CTT increased in the electroacupuncture group,and the differences were statistically significant(all P＜0.05).Corneal HE staining showed that after the intervention,the corneal surface of rats in the model group and sham acupuncture group was not smooth,and the corneal epithelial cells were thickened and disorganized;the corneal surface of rats in the electroacupuncture group and fluorometholone group was smooth,and the corneal epithelial cells were arranged neatly.After the intervention,compared with the blank group,the corneal TLR4 expression of rats in all other groups was elevated,and the differences were statistically significant(all P＜0.05);compared with the model group,the corneal TLR4 expression of rats in the electroacupuncture group and fluorometholone group was reduced(both P＜0.01).Compared with the blank group,corneal TLR4,P-NF-κBP65,IL-1β and IL-18 protein expressions increased in the model group and sham acupuncture group(all P＜0.05);compared with the model group,these expressions decreased in the electroacupuncture group and the fluorometholone group(all P＜0.05).Conclusion Electroacupuncture can im-prove the ocular surface signs and inhibit the expressions of TLR4,P-NF-κB P65,IL-1 β,and IL-18 in the cornea of type 2 diabetic dry eye rats,and its mechanism of action may be related to the regulation of TLR4-mediated inflammatory signaling pathway,which inhibits ocular surface inflammation in diabetic dry eye rats.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Objective:To assess the prognostic impact of frailty on elderly inpatients with heart failure.Methods:This prospective cohort study enrolled 121 in elderly patients with heart failure from Beijing Hospital, the General Hospital of the People's Liberation Army, and Beijing Tsinghua Changgung Hospital between September 2018 and April 2019.Patients were assessed for frailty using the Fried frailty phenotype and categorized into frail and non-frail groups.Follow-ups were conducted at 3-, 6-, and 12-months post-enrollment through clinic visits or phone calls to record adverse events.Composite endpoints include all-cause mortality and rehospitalization duo to deterioration of heart failure.Results:The study included 121 patients with an average age of 78.0±7.4 years, of whom 71(58.7%)were male and 57(47.1%)were classified as frail.Compared to the non-frail group, the frail group had lower estimated glomerular filtration rates[49.5±20.7 ml/(min·1.73m 2) vs.(64.0±27.1)ml/(min·1.73m 2)], lower scores in Basic Activities of Daily Living[5.0(4.0, 6.0) vs.6.0(5.0, 6.0)], Instrumental Activities of Daily Living[2.0(1.3, 7.8) vs.7.0(5.0, 8.0)], and Mini-Mental State Examination[26.0(16.0, 28.0) vs.27.0(22.3, 29.0)], all P<0.05.They also experienced longer hospital stays[10.5(6.0, 18.8)days vs.8.0(6.0, 11.8)days, P=0.008].During the follow-up period, the incidence of composite endpoint events was significantly higher in the frail group(43.9% vs.25.0%, P=0.029).Kaplan-Meier survival analysis demonstrated that the one-year incidence of composite endpoint events was significantly higher in the frail group( P=0.013).Multivariable Cox regression analysisindicated that frailty was an independent risk factor for composite endpoint events( HR=2.201, 95% CI: 1.089-4.447, P=0.028). Conclusions:Frailty is an independent risk factor for poor outcomes in elderly hospitalized patients with heart failure and should be considered a crucial factor in clinical assessment and treatment strategies.

Volume electron microscopy (vEM) imaging technology was rapidly developed in recent years. It has been the advanced technology to solve high-resolution three-dimensional structures of biological samples. Much wonderful work has revealed the fine structure and interactions of intracellular organelles, the ultrastructure of tissues, and even the three-dimensional structure of entire small biological organisms. With the continuous improvement of resolution, scale and throughput, vEM is becoming more and more widely used in medicine, life sciences, clinical diagnostics and other fields. As a result, this technology has been rated by Nature as one of the seven most noteworthy frontier technologies to watch in 2023. However, the development and application of vEM-related technologies started late in China and need to be further promoted. We write this review to introduce all related vEM technologies, covering the development history of vEM, technology classification, sample preparation, data collection, image processing, etc., which is convenient for people in various fields to understand, learn, apply and further develop this technology.

The paper is to establish an UPLC-MS/MS method for the simultaneous determination of 19 components in Microctis Folium from different production areas. The 50% methanol was used as extraction solvent. The Agilent ZORBAX SB C18 (150 mm × 2.1 mm, 1.8 μm) column was used; mobile phase was acetonitrile - 0.1% acetic acid with gradient elution, flow rate was 0.3 mL·min^-1, colume temperature was 30 ℃, and the injection volume was 2 μL; electrospray ionizaton source was used and detected in negative ion mode. The results showed that the established UPLC-MS/MS method could well separate the 19 components, and the methodological investigation results of 19 components were good. By means of orthogonal partial least squares discriminant analysis (OPLS-DA), 28 batches of Microctis Folium samples from different production areas can be divided into three categories, Guangdong, Guangxi and Hainan are each classified into one category, and 10 signature compounds which affecting the quality differences of different production areas were screened out. The established method is accurate, reliable, sensitive and reproducible. It can provide a basis for the establishment of the quality standard of Microctis Folium, as well as for safety and quality research.
