Objective To explore the optimization and effect analysis method of rational drug use pre-prescription review rule base for traditional Chinese medicine(TCM).Methods The rules for the modules including indications,dosage range,incompatibility,administration route and repeated drug use of TCM decoction pieces and Chinese patent medicine were set to improve pre-prescription review rule base.The prescription rationality rate and intervention effectiveness rate to evaluate effect by χ2 test before and after the system optimization.Results After the optimization of pre-prescription review rule base for TCM,the rate of prescription rationality of the hospital increased from approximately 78.19%to 94.50%,and the rate of intervention effectiveness increased from approximately 82.80%to 97.15%.There were statistically significant differences in prescription rationality and intervention effectiveness rate between pre-and post-optimization groups(P＜0.05).Conclusion According to the current pre-prescription status of the hospital,optimizing pre-prescription review rules of TCM can improve the applicability of the review system for TCM prescriptions,and enhance the pre-prescription accuracy and the level of rational medication.However,rules optimization on other modules still needs to be further improved.

Objective:To analyze the epidemiological and clinical characteristics of respiratory pathogens in China.Methods:This study was a cross-sectional study, which encompassed 19 core units of the clinical pathogen network and established a three-tiered clinical pathogen surveillance system. Thirty respiratory samples were collected every two weeks from various units from January to December 2024, and the clinical and pathogen diagnostic information were gathered. A total of 11 864 samples were tested using this system. The tier-1 clinical pathogen surveillance system covered influenza A virus (Flu-A), influenza B virus (Flu-B), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The tier-2 clinical pathogen surveillance system focused on 18 key respiratory pathogens. The tier-3 clinical pathogen surveillance system further clarified whether any emerging infectious diseases had occurred.Results:The tier-1 clinical pathogen surveillance system showed Flu-A predominated in December, Flu-B predominated in January, SARS-CoV-2 peaked in March and August, whereas RSV circulated sporadically throughout the year. Geographic trends were broadly consistent across the seven major regions, although Flu-A detection in December was notably higher in Northeast China (48.1%(111/231)) and East China (36.2%(148/409)), and RSV detection was concentrated in the Northwest and South China from January to March. Data from the tier-2 clinical pathogen surveillance system indicated that Streptococcus pneumoniae, Mycoplasma pneumoniae, rhinovirus, and adenovirus were detected year-round, of these, Streptococcus pneumoniae and rhinovirus showed elevated positive detection rates from August to September, while adenovirus peaked in January. Legionella pneumophila was not detected throughout the year, and other pathogens fluctuated throughout the year without a consistent pattern. The predominant etiologic agents of pediatric pneumonia were Mycoplasma pneumoniae (35.0%(105/300)), rhinovirus (25.7%(77/300)), and adenovirus (17.3%(52/300)), whereas adult pneumonia was mainly caused by Streptococcus pneumoniae (10.5%(29/277)), Staphylococcus aureus (6.9%(19/277)), Mycoplasma pneumoniae (6.9%(19/277)), and Flu-A (6.1%(17/277)). The tier-3 clinical pathogen surveillance system did not identify any emerging respiratory pathogens. Conclusion:Respiratory pathogens in China in 2024 exhibit distinct temporal and spatial distribution patterns and vary among different populations.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Objective: To establish an autoregressive moving average model for the prediction of tuberculosis cases in students of Shanxi Province, and to provide scientific basic for the prevention and treatment of pulmonary tuerculosis among students. Methods: A optimized ARIMA model was set up based on reported monthly data of TB in students from January 2010 to September 2019 in Shanxi Province by SAS 9.3 software, and the incidence trend in the next two years was predicted. Results: The average reported rate of active TB in students of Shanxi Province was 23.52 per 100 000 from 2010 to 2019,showing an overall downward trend(χ2=999 980.46，P<0.01). The optimal model was SARIMA(0，1，1)(0，1，1)12,SBC=982.16. The fitted equation was (1-0.63B) (1-B12)Yt=(1-0.61B12)εt. The mean relative error was 19.35%,and the predicted incidence trend was consistent with the previous years,and the peak was from March to May. Conclusion Substantial progress has been made in student TB prevention of Shanxi Province. The ARIMA product season model is suitable for forecasting the TB incidence in students,so as to provide scientific guidance for its early prevention and control.

Objective:It is yet to be clarified whether pylorus-preserving gastrectomy (PPG) for early gastric cancer will bring the risk of radical tumor resection, whether it will increase the incidence of postoperative complications, and how much is the benefit of the quality of life for patients after surgery, these issues are not clear. This meta-analysis aims to evaluate the efficacy and safety of pylorus-preserving gastrectomy (PPG) for early middle gastric cancer.Methods:The Chinese and English literatures about PPG and distal gastrectomy (DG) for early gastric cancer were searched from PubMed, Embase, The Cochrane Library, Web of Science, CNKI net and Wanfang database. Literature inclusion criteria: (1) Prospective or retrospective cohort study of PPG and DG for early middle-third gastric cancer published publicly; (2) Patients with early middle-third gastric cancer; (3) The enrolled literatures include at least one of the following outcome indicators: the efficacy indicators include gallstone, residual gastritis, bile reflux, delayed gastric emptying, dumping syndrome, reflux esophagitis and overall complication; the long-term prognostic indicators include 5-year survival rate and 5-year tumor recurrence. Literature exclusion criteria: (1) Reviews, case reports, conference summaries and other non-control studies; (2) Repeated published studies, incomplete studies and unextractable studies; (3) The depth of tumor invasion exceeding submucosa. The search time ended in July 2020. The basic information and evaluation indicators included in the article were extracted. The retrospective study was evaluated using Newcastle-Ottawa literature quality evaluation scale. The prospective randomized controlled study was evaluated using Jadad modified scale. Meta-analysis was performed using Review Manager 5.3. Publication bias was assessed using funnel map. Publication bias was tested using Egger tools.Results:A total of 717 literatures were retrieved, and 17 literatures were enrolled finally, including 2 randomized controlled trials and 15 retrospective studies. A total of 2427 patients were enrolled, including 948 in PPG group and 1479 in DG group. The meta-analysis of the efficacy indicators showed that there were significant differences in gallstones incidence (OR=0.42, 95% CI: 0.28-0.65, P<0.001), residual gastritis incidence (OR=0.50, 95% CI: 0.32-0.77, P=0.002), bile reflux incidence (OR=0.30, 95% CI: 0.20-0.45, P<0.001), delayed gastric emptying incidence (OR=2.40, 95% CI:1.67-3.45, P<0.001), and postoperative dumping syndrome incidence (OR=0.28, 95% CI: 0.15-0.51, P<0.001), while there were no significant differences in postoperative overall complications (OR=0.97, 95% CI: 0.69-1.35, P=0.840), reflux esophagitis incidence (OR=0.79, 95% CI: 0.39-1.61, P=0.520) between the two groups. The meta-analysis of the long-term prognostic indicators showed that no significant differences of 5-year survival (OR=1.02, 95% CI: 0.61-1.71, P=0.940) or 5-year tumor recurrence (OR=0.77, 95% CI: 0.36-1.68, P=0.520) were observed between the two groups. Conclusion:The incidences of gallstone, residual gastritis, dumping syndrome, bile reflux are lower after PPG in early gastric cancer, while the postoperative overall complications and long-term survival are comparable between PPG and DG, indicating that PPG is quite safe and feasible.

OBJECTIVETo assess the feasibility of chromosomal microarray analysis(CMA) for studying the correlation between birth defects and chromosomal aberrations.

METHODSA total of 2000 patients with birth defects were recruited for the CMA testing.

RESULTSFive hundred twenty two patients (26.1%) were found to have chromosomal abnormalities. These included 24 cases with numerical abnormalities, 11 with mosaicisms, and 11 with uniparental disomies. The remaining 476 cases were of well-known microdeletion or microduplication syndromes. The advantage of CMA over conventional karyotyping was demonstrated in many cases.

CONCLUSIONAs a powerful tool for patients with birth defects, CMA can produce a higher diagnostic yield compared with conventional karyotyping.

Objective To explore the safety and feasibility of guiding catheter passing through spasmodic vessels in patients undergoing percutaneous coronary intervention (PCI) via radial artery access by the aid of PCI guiding wire and balloon .Methods The clinical data of 33 coronary artery disease (CAD) patients undergoing PCI via radial artery access with radial artery or (and) brachial artery spasm ( group A ) were retrospectively analyzed .Among all these patients , guiding catheters were delivered through the spasmodic vessels successfully by the aid of PCI guiding wires and balloons .The clinical data of other 38 CAD patients having PCI during the same period performed by other operators via radial artery or ( and ) brachial artery approach and experienced vessel spasm were anlysed as the control ( group B ) .All patients in group B received conventional anti-spasm management during PCI .All vessel spasm was identified by angiography.For patients in group A , a diameter of 0.014 inch guiding wire was chosen to pass through the spasmodic vessel segment carefully and gently .The diameter of balloon should be chosen according to the diameter of guiding catheter .A balloon diameter of 2.0 mm and 2.5 mm was corresponded to 6F and 7F guiding catheter respectively .The balloon was advanced to the tip of guiding catheter , keeping a half in catheter and a half in vessel followed by inflating the balloon with a pressure of 8 atm.The balloon was kept inflated the guiding catheter was pushed in vitro carefully and slowly until the catheter passed through the spasmodic vessel segment .Then the balloon was deflated and pulled out together with PCI guiding wire . Exchanged a diameter of 0.035 inch wire and completed the positioning of guiding catheter .After finishing the PCI, radial or ( and) brachial angiography was performed again to observe if spasm disappeared and to determine if there any contrast medium exudation .For patients in group B , routine approach was applied including administration of nitroglycerine , diltiazem or nitroprusside etc . to relieve vessel spasm. Results The location of vessel spasm was similar in group A and group B ( P=0.150 ) , and the incidence rate of spasm in brachial artery was higher than that in radial artery in both groups .The chance of guiding catheter crossing the spasmodic vessel segment was significantly higher in group A than in group B ( 100%vs.39.5%, P=0.00).In patients whose guiding catheter could pass through the spasmodic vessel segment successfully , time spent in group A was shorter than in group B ( P=0.000 ) .The patient number which time spent was less than five minutes , five to 15 minutes and more than 15 minutes was 30 and 2 ( 90.1%vs.13.3%) , 3 and 7 ( 9.9% vs.46.7%) and 0 and 6 ( 0% vs.40.0%) in group A and in group B respectively.The incidence of forearm hematoma was lower in group A than in group B without statistical difference [6.1%(2/33) vs.18.4%(7/38), P =0.113].Conclusions It is safe and feasible for passing guiding catheter through spasmodic vessels during PCI via radial artery access by the aid of PCI guiding wire and balloon .
