ObjectiveTo observe the clinical efficacy of acupuncture combined with bloodletting and cupping in the treatment of chronic spontaneous urticaria（CSU） and to explore its potential mechanisms of action. MethodsSeventy CSU patients were randomly divided into loratadine group and acupuncture + bloodletting group， with 35 patients in each group. The loratadine group received oral loratadine tablets， 10 mg once daily in the evening. The acupuncture + bloodletting group received acupuncture at Zhongwan （CV 12）， Guanyuan （CV 4）， Tianshu （ST 25）， Zusanli （ST 36）， Sanyinjiao （SP 6）， Xuehai （SP 10）， Quchi （LI 11）， Hegu （LI 4）， Taichong （LR 3）， Baihui （GV 20）， and Shenting （GV 24）， once daily，along with bloodletting and cupping at Dazhui （GV 14） and Geshu （BL 17）， every other day. Both groups were treated for 4 weeks. The 7-day urticaria activity score（UAS7） was assessed before and after the treatment， and levels of serum immunoglobulin E （IgE）， interleukin-4 （IL-4）， interleukin-5 （IL-5）， eosinophil cationic protein （ECP）， plasma tissue factor （TF）， activated factor Ⅶ （FⅦa）， prothrombin fragment 1+2 （F1+2）， D-dimer （D-D） and complement component 5a （C5a） were detected. ResultsA total of 65 patients were included in the final analysis， 32 in the loratadine group and 33 in the acupuncture + bloodletting group. Before treatment， there was no significant difference in UAS7 score， serum IgE， IL-4， IL-5， ECP levels， or plasma TF， FⅦa， F1+2， D-D， C5a levels between groups （P＞ 0.05）. After treatment， both groups showed significant reductions in UAS7 score， serum IgE， IL-4， IL-5， and plasma TF， FⅦa， F1+2， D-D， and C5a levels compared to those before treatment （P＜0.01）. However， after treatment， there was no significant difference in UAS7 score and serum ECP， IgE， IL-4， IL-5 levels between groups （P＞0.05）. The acupuncture + bloodletting group showed lower plasma TF， FⅦa， F1+2， D-D and C5a levels compared to the loratadine group （P＜0.05 or P＜0.01）. ConclusionAcupuncture combined with bloodletting and cupping can effectively improve the skin symptoms of CSU patients and reduce the levels of inflammatory factors. The potential mechanism of action may involve the regulation of the coagulation-complement-mast cell activation axis， thereby inhibiting mast cell degranulation.

It is believed that the cause of recurrent trigeminal neuralgia is mainly physical injuries and emotional distress. The core pathogenesis lies in the blockage of meridians and disharmony between the body and mind. Therefore， it is proposed that the treatment should focus on simultaneously regulating the body and the mind， with the therapeutic methods of unblocking the meridians and collaterals， soothing the liver and moving qi， and regulating the mind to relieve pain. In clinical practice， liver-soothing and mind-regulating acupuncture combined with para-nerve acupuncture are commonly used， and puncturing upto the bone is applied to strengthen the analgesic effect， providing a new diagnosis and treatment idea for clinical treatment of recurrent trigeminal neuralgia with acupuncture.

Guideline of model-informed drug de-velopment was published by National Medical Products Administration in 2020,which provided technical guidance for the application of modeling and simulation in the process of new drug develop-ment.In July 2022,Center of Drug Evaluation con-ducted a questionnaire survey on the practical abili-ty of pharmaceutical industry to apply model-in-formed drug development(MIDD)in the process of new drug development,in order to investigate the practice of MIDD in China.Based on the feedback data collected from enterprises,this paper analyzes the practice of MIDD in domestic pharmaceutical industry,and briefly discusses several problems that still exist at present.

The incidence of coronary heart disease is increasing year by year,with the mortality rate rank-ing first.Early prevention,diagnosis,and treatment are crucial to reduce the mortality rate.Coronary angiography is the gold standard for diagnosing coronary heart disease and is widely used in clinical practice,but it cannot accu-rately reflect the degree of coronary artery disease.Blood flow reserve fraction(FFR)is currently the reference standard for evaluating coronary artery stenosis function.However,it is an invasive examination that is limited in clinical application due to factors such as complex operation,high cost,multiple side effects related to vasodila-tors,and poor reproducibility.In recent years,non-invasive blood flow reserve scores related to imaging have been increasingly applied in clinical practice.Quantitative flow fraction(QFR)and optical coherence tomography based flow reserve fraction(OCT based optical flow ratio OFR)have become research hotspots.OFR,as a relatively new technology,has received increasing attention.Therefore,this article will describe the basic principles,clinical value,and research progress of the above-mentioned technologies.

Primary hyperoxaluria(PH)is a rare autosomal recessive disorder,with PH type 1(PH1)being the most common.It is primarily characterized by recurrent renal calculi,renal calcification,and can lead to acute renal failure.In infants,PH1 often results in early end-stage renal disease(ESRD)with a high mortality rate.This paper reports a case of an infant with acute renal failure in the Second Hospital of Shandong University who was diagnosed as PH1 using whole-exome sequencing,revealing a homozygous mutation in the AGXT gene(c.596-2A＞G),which is reported here for the first time in the Chinese population.Previous literature indicates that urinary oxalate levels and stone composition can suggest PH1,with the gold standard for diagnosis being liver biopsy combined with alanine-glyoxylate aminotransferase(AGT)enzyme activity assessment.However,due to its convenience,AGXT gene sequencing has increasingly become the preferred diagnostic method.Conservative treatments for PH1 include adequate fluid intake,citrate,vitamin B6,and continuous renal replacement therapy,while liver transplantation is the only curative treatment.Infants with unexplained acute renal failure should be evaluated for PH1,with early detection of the level of urine oxalate and screening for genetic testing recommended.

Allergic rhinitis is a common allergic disease in children.Its pathogenesis is complex and it is difficult to achieve radi-cal cure or effective and stable long-term treatment goals.Chinese medicine has obvious advantages in preventing and treating allergic rhinitis in children due to its wide range of targets,long-lasting effects and few adverse reactions.This paper proposes that the onset of allergic rhinitis is mostly caused by the dysfunction of the lung,spleen and kidney,the external wind triggering the latent wind,and the combination of the two winds.A staged prevention and treatment strategy of Chinese medicine should be adopted,which includes dispersing external wind,suppressing latent wind,and promoting lung-qi and clearing nasal orifice during the attack period to treat its symptoms,and preventing external wind,calming down latent wind,and regulating and tonifying the lung,spleen,and kidney during the remission period to treat its root cause;meanwhile,attention should be paid to avoiding the adverse effects of congenital endowment factors and the induction of acquired environmental factors,strengthening the body's health to protect against the evil wind,preventing the transformation of existing diseases and the recurrence of allergic rhinitis in children at all stages.

[Objective]To explore if the enhanced recovery after surgery (ERAS) protocol for pregnant women with gestational diabetes mellitus (GDM) who are undergoing elective cesarean delivery could cause perioperative glycemic abnormalities and heighten the risk of neonatal hypoglycemia.[Methods]A retrospective analysis was conducted on a cohort of pregnant women with singleton pregnancies who underwent elective cesarean sections and received ERAS between May 1,2022,and October 31,2023,at the Third Affiliated Hospital of Sun Yat-sen University. A total of 150 patients were included in this study,comprising the GDM group (n=75) and the non-GDM group (n=75). The study included pregnant women with good glycemic control (GDM) and maternal age (18-30 years;30-35 years;35-40 years;>40 years),BMI (<18.5 kg/m2;18.5-24.9 kg/m2;25-30 kg/m2;>30 kg/m2),and gestational age (within 7 days). We used these criteria to match 1∶1 non-GDM women as the control group. After administering preoperative oral carbohydrates,we observed the trends of maternal glycemic changes,including hyperglycemia and hypoglycemia,at any time of the day. We also evaluated the incidence of hypoglycemic low Apgar scores in newborns,abnormal pH values in blood gases,and the rate of transfer to the pediatric unit immediately after delivery.[Results]No significant difference was observed in fasting blood glucose levels on the day of surgery between the two groups of pregnant women[(4.4±0.5) mmol/L vs. (4.3±0.5) mmol/L,t=1.395,P=0.165]. The blood glucose peak was reached 30 minutes after consuming 300 mL (42.6 g of low-dose carbohydrate) of a light drink[(7.2±0.9) mmol/L vs. (6.4±0.8) mmol/L,t=5.773,P<0.001],with a subsequent decline in blood glucose levels. At the 120-minute mark,blood glucose had returned to the pre-oral carbohydrate level. The blood glucose levels in GDM groups was significantly higher than those in the non-GDM group (P<0.005). Although the incidence of hyperglycemia was significantly higher in the GDM group than in the non-GDM group at the 30-minute peak blood glucose level after oral carbohydrate intake,and the difference was statistically significant (17.3％ vs. 1.3％,x2=11.354,P<0.001),severe hyperglycemia (≥10 mmol/L) did not occur. The incidence of hypoglycemia was not significantly higher in neonates in the GDM group than in the non-GDM group (22.7％ vs. 28％,x2=0.564,P=0.453). The incidence of neonatal hypoglycemia in the GDM group was not significantly elevated in comparison to the non-GDM group after adjusting for age and BMI (Model 1),primiparity and gestational week of delivery (Model 2),hypertensive disorders of pregnancy (Model 3),cesarean section indications,time of cesarean section,and intraoperative hemorrhage (Model 4),and neonatal weight (Model 5).[Conclusion]In GDM patients with excellent glycemic control,an ERAS regimen with a low oral dose of carbohydrates prior to elective cesarean section does not increase the risk of preoperative serious hyperglycemia in mothers,nor does it increase the incidence of neonatal hypoglycemia.

Objective:To describe the characteristics, etiology and patterns of outpatients and inpatients patients with moderate or severe valvular heart disease (VHD).Methods:This is a cross-sectional study. Outpatients and inpatients with moderate or severe VHD who underwent transthoracic echocardiography for first examination from 1 st January 2001 to 1 st January 2020 in Southwest Hospital, Army Medical University were enrolled. Data were collected from medical records and big data platform of Southwest Hospital. Characteristics of age and gender, etiology and types of VHD were descriptively analysed. Results:A total of 68 354 patients with moderate or severe VHD were enrolled. The age was 63 (50, 72) years. And 35 706 (52.24%) patients were female. (1) Age characteristics: There was similar age trend between male and female patients with moderate or severe VHD. The number of patients increased firstly and then decreased and reached its peak in the age group of 65-69 years old. The peak age of mitral stenosis patients was 45-49 years, which was earlier than that of whole patients with moderate or severe VHD. The median age of patients with bicuspid aortic valve was 42 years. (2) Gender characteristics: The proportion of tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, mitral stenosis and valve surgery in female patients with moderate or severe VHD were higher than those in male patients. The proportion of aortic regurgitation, aortic stenosis and bicuspid aortic valve in male patients with moderate or severe VHD were significantly higher than those in female patients (all P<0.05). (3) Etiology: The proportion of rheumatic VHD was 13.07% (8 934/68 354), which was higher than that of degenerative VHD (0.67% (458/68 354)). (4) Types of VHD: Tricuspid regurgitation made contribution to the largest proportion with 60.72% (41 503/68 354), followed by mitral regurgitation, aortic regurgitation, mitral stenosis, pulmonary regurgitation and aortic stenosis. Conclusions:There are certain regional characteristics in the prevalence of moderate or severe VHD in southwest China, suggesting different attention should be paid on the whole process of refined management of moderate or severe VHD.

With the advancement of comprehensive treatment and minimally invasive technology, patients with originally unresectable gallbladder cancer are expected to undergo surgical treatment after transformational therapy, which can achieve the effect of increasing R0 resection rate and improving long-term prognosis. Conversion therapy as a new option for patients with gallbladder cancer who are difficult to undergo radical surgery is still subject to much debate. Patients with locally progressive gallbladder cancer at the initial diagnosis may be the target population for conversion therapy. Gemcitabine+ cisplatin is still used as the standard first-line chemotherapy regimen. The use of multiple chemotherapeutic agents in combination also shows new vitality. High-throughput sequencing and the use of precision targeting drugs will become new trends in the future. The use of immune drugs is still needed. And the use of immunotherapy drugs is still in demand. High-throughput sequencing and the use of precision-targeted drugs will become a new trend in the future, the use of immunologic drugs still needs more evidence-based medical support, and the use of post-translational minimally invasive techniques may bring benefits to patients.

The National Health Commission's Implementation Plan for the Development of Women and Children in China(2021-2030),released in 2022,has set a clear goal that:by 2030,we should train 1.12 pediatrician practitioners and add up to 3.17 hospital beds for every 1 000 children.Achieving the goal on schedule presents a significant challenge for children's hospi-tals,particularly in terms of attracting and retaining pediatric medical professionals to ensure the health of children.This paper addresses this issue by applying the 4 Ps model of employer branding theory,drawing on the experience of pediatrician recruit-ment and retention in Tianjin.The exploration encompasses several key areas:the work demands of pediatricians,employer brand positioning,human resource offerings,and employer brand promotion.It aims to enhance the appeal of pediatric medical institutions to pediatricians,thereby achieving effective recruitment and retention of talent within these institutions.Furthermore,by reviewing theoretical literature at home and abroad,this paper also proposes systematic ideas and approaches to improving employer branding.The proposed employer branding strategy in the paper is designed to enhance the effectiveness of employer branding for pediatric medical institutions,enabling them to secure a competitive edge in the attraction and retention of talent.Additionally,the paper of-fers a guidance for similar medical institutions,contributing to the advancement and expansion of pediatric medical institutions.
