OBJECTIVE To investigate the mechanism of Zuogui pill in improving pancreatic β cell function in the offspring of rats with gestational diabetes mellitus （GDM）.METHODS Thirty-six pregnant rats were divided into normal group， model group， insulin glargine group （positive control）， and low-， medium- and high-dose Zuogui pill groups， with 6 rats in each group. The normal group and model group were given intragastric administration of equal-volume normal saline. The insulin glargine group was subcutaneously injected with insulin glargine at an initial dose of 1 U/kg， and the dosage was increased by 1 U per day until random blood glucose returned to normal. The low-， medium- and high-dose Zuogui pill groups were intragastrically administered with Zuogui pill solutions at 4.725， 9.45 and 18.9 g/kg once a day until the birth of offspring. On postnatal day 21 （12 offspring in each group）， body weight， fasting blood glucose （FBG） and oral glucose tolerance test were performed on the offspring. Pancreatic histopathological changes of 60-day-old offspring were observed. The insulin-positive expression area ratio in pancreatic tissue， serum levels of glycated serum protein （GSP）， high-density lipoprotein cholesterol （HDL-C） and low-density lipoprotein cholesterol （LDL-C）， as well as the mRNA and protein relative expression levels of wingless-type MMTV integration site family member 7a（Wnt7a）and glycogen synthase kinase 3β（GSK-3β） in pancreatic tissue were detected.RESULTS Compared with normal group， the body weight， insulin-positive expression area ratio in pancreatic tissue， serum HDL-C level， and the mRNA and protein relative expression levels of Wnt7a in pancreatic tissue were significantly decreased of the offspring in the model group （ P ＜0.05）. Meanwhile， FBG， blood glucose levels at 60， 90 and 120 min after intragastric administration of 20% glucose solution， serum GSP and LDL-C levels， as well as the mRNA and protein relative expression levels of GSK-3β in pancreatic tissue were significantly increased （ P ＜0.05）；mild degeneration and necrosis of islet cells were observed in pancreatic tissue. Compared with the model group， the above-mentioned indexes were significantly reversed in medium- and high-dose Zuogui pill groups （ P ＜0.05）， and pancreatic pathological injury was improved to varying degrees.CONCLUSIONS Zuogui pill may restore the homeostasis of Wnt7a/GSK-3β signaling axis， so as to improve pancreatic β cell function in the offspring of GDM rats.

Objective To establish a technical system for allogeneic kidney transplantation surgery in pigs using the Banna miniature pig inbred strain,and to evaluate it through routine blood tests,liver and kidney function tests,thus providing reference data for the preparation of allogeneic kidney transplantation models.Methods A total of 4 cases of allogeneic kidney transplantation surgeries were performed,including 1 case of single kidney transplantation in a healthy pig,2 cases of kidney transplantation after unilateral nephrectomy,and 1 case of kidney transplantation after bilateral nephrectomy.Before kidney transplantation,cross-matching and complement-dependent cytotoxicity(CDC)tests were used for matching between donor and recipient pigs.After kidney transplantation,peripheral blood samples were regularly collected from pigs for routine blood tests,liver function tests,and kidney function tests,and color Doppler ultrasound technology was used to detect blood supply to the transplanted kidneys.After reaching the experimental endpoint,both kidneys of pig DR1 and the left kidney of pig DR3 were collected and hematoxylin-eosin(HE)staining was performed to evaluate pathological changes in the transplanted kidneys.Results Recipient pigs DR1 and DR3 died at 17 days and 30 days after surgery respectively,while recipient pigs R and DR2 remained in good condition during the 30-day observation period.The results of liver and kidney function test showed that in pig DR1,alanine aminotransferase(ALT)levels increased on postoperative day 1(＞1 000 U/L),peaked on postoperative day 7(1 300 U/L),and aspartate aminotransferase(AST)levels peaked on postoperative day 1(＞3 000 U/L).On postoperative day 17,ALT and AST levels remained high(ALT,500 U/L;AST,700 U/L).In pigs R,DR2,and DR3,ALT and AST levels returned to normal around day 17.Serum creatinine(Crea)levels in pig R remained stable without postoperative increase.Crea levels in pigs DR1 and DR2 showed transient elevation on postoperative day 1,then gradually returned to normal(＜100 μmol/L).Crea levels in pig DR3 remained below 500 μmol/L from postoperative days 2-10,but increased between days 11-28,reaching up to 1 500 μmol/L,indicating gradual loss of kidney function.Ultrasound results showed that the preoperative resistive index(RI)of recipient pig R was 0.91.On postoperative day 24,renal cortex and medulla showed abundant blood flow signals with RI value of 0.88,which was close to the pre-transplantation RI value.For pig DR2,the RI value on postoperative day 17 was 0.89,with poor renal cortex blood flow and relatively good renal medulla blood flow.In pig DR1 on postoperative day 17,no blood flow signals were detected in the transplanted kidney.HE staining results showed that the non-transplanted healthy right kidney of pig DR1 had normal structure,while the transplanted left kidney showed blurred glomerular structure and nuclear dissolution,indicating that the left kidney had lost function before removal.In the transplanted left kidney of pig DR3,large numbers of red blood cells and lymphocyte infiltration were observed in glomeruli and renal tubules,indicating possible coagulation dysfunction and rejection reactions after kidney transplantation.Conclusion Banna miniature pig inbred strain is used as experimental animals to perform four cases of allogeneic pig-to-pig kidney transplantation.The physiological parameters of the recipient pig and the function of the transplanted kidney are monitored after surgery using routine blood tests,liver and kidney function tests,color Doppler ultrasound,and pathological examinations.The allogeneic pig-to-pig kidney transplantation technical system established in the study can provide a foundation for clinicians to conduct kidney transplantation surgeries.

Follicular lymphoma(FL)is a type of non-Hodgkin's lymphoma,and its treatment options face many challenges.This paper discusses the pathogenesis and treatment of FL based on the clear-turbid theory in traditional Chinese medicine(TCM)."The clear and the turbid being related,and the rise and fall of qi being disorderly"is the basic pathogenesis of FL.As the disease progres-ses,"evil qi being blocked inside,and turbid evil harming the clear"aggravates,and finally"evil qi is strong and the disease progres-ses,and evil poison is generated inside".Based on this theory,the method of raising the clear and lowering the turbid and the method of dispersing the clear and removing the turbid are proposed to treat FL.The emphasis of raising the clear and lowering the turbid is to take raising and lowering as the key,movement and stillness as the pivot,and to treat the middle jiao;the emphasis of dispersing the clear and removing the turbid is to clear the triple jiao,warm the yang and invigorate the qi,and harmonize the spleen and kidney.Ca-ses are attached to illustrate,providing new ideas for the TCM treatment of FL.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal hematopoietic stem cell disease caused by abnormal expression of glycosylphosphatidylinositol (GPI) on the cell membrane due to mutations in the phosphatidylinositol glycan class A(PIGA) gene. It is commonly characterized by intravascular hemolysis, repeated thrombosis, and bone marrow failure, as well as multiple systemic involvement symptoms such as renal dysfunction, pulmonary hypertension, swallowing difficulties, chest pain, abdominal pain, and erectile dysfunction. Due to the rarity of PNH and its strong heterogeneity in clinical manifestations, multidisciplinary collaboration is often required for diagnosis and treatment. Peking Union Medical College Hospital, relying on the rare disease diagnosis and treatment platform, has invited multidisciplinary clinical experts to form a unified opinion on the diagnosis and treatment of PNH, and formulated the Expert Consensus of Multidisciplinary Diagnosis and Treatment for Paroxysmal Nocturnal Hemoglobinuria (2024), with the hope of promoting the standardization of PNH diagnosis and treatment.

Objective To explore the dynamic changes in cerebral hemodynamics in patients with unilateral middle cerebral artery(MCA)occlusion after superficial temporal artery(STA)-MCA bypass surgery.Methods One hundred and nine patients diagnosed with unilateral MCA occlusion by DSA who underwent STA-MCA bypass surgery were retrospectively included in the Department of Neurosurgery of the First Affiliated Hospital of Soochow University.Clinical data of patients were collected within 24 hours after admission,including age,sex,body mass index,stroke risk factors including hypertension,hyperlipidemia,diabetes,smoking,drinking history and atrial fibrillation,clinical manifestations(within the last 6 months;nonspecific symptoms[dizziness,memory loss,unresponsiveness,etc.],transient ischemic attack,and stroke),blood biochemical markers(low density lipoprotein cholesterol,high density lipoprotein cholesterol,triglyceride,total cholesterol,fasting blood glucose,and hypersensitive C-reactive protein),and National Institutes of Health stroke scale(NIHSS)score at admission.Color Doppler ultrasound(CDU)and transcranial color coded Doppler(TCCD)ultrasound were used to evaluate the hemodynamic parameters of STA before and at different periods after surgery(4-7 days and 1,3,6,12 months after surgery)to analyze the patency of bypass arteries and intracranial hemodynamic changes,and to check the consistency of the results of the bridge artery patency at 12 months postoperatively by CDU and DSA,consistency test was performed.According to the results of the DSA examination 12months after surgery,the patients were divided into the bypass artery patency group and the non-patency group(stenosis or occlusion).The hemodynamic parameters at the trunk of STA,namely the extracranial segment,transcranial,and intracranial part of the bypass arteries,were compared between the two groups.It included inner diameter(D),peak systolic velocity(PSV),end-diastolic velocity(EDV),resistance index(RI),pulsation index(PI),time-averaged mean velocity(TAMV),time-averaged peak velocity(TAPV),and calculated flow of the STA trunk including TAMV flow and TAPV flow.Head CT,CT angiography(CTA)above the aortic arch,and CT perfusion(CTP)of the whole brain were performed 1 to 3 days before surgery and 12 and 18 months after surgery to observe the changes in cerebral perfusion.Head CT was performed 1 to 2 days after the operation to observe whether there were new hemorrhagic and ischemic lesions in the operative area.the CTP parameters of the two groups were compared including 12 and 18 months after the operation with 1 to 3 days before the surgery,and the differences in CTP parameters between the two groups were compared.The modified Rankin scale(mRS)was used to evaluate the neurological function prognosis of the patients at 12 and 18 months after surgery.The mRS score 2 was divided into a good prognosis and mRS score≥3 was a poor prognosis.NIHSS score of the patients was recorded 7 days,12,and 18 months after surgery.Results(1)Consistency analysis of CDU and DSA:the consistency of the assessment of bypass artery patency was excellent at 12 months after surgery,and the Kappa value was 0.94(95％CI 0.81-1.00,P＜0.01).According to DSA,101 cases(92.7％)were in bypass artery patency group,while 8 cases(7.3％)in the non-patency group(no case of occluded bridge vessel was found),and the sites of stenosis in the bypass arteries were all located in the transcranial segment.(2)Hemodynamic parameters:compared with the preoperative results,the D of the extracranial segment increased on 4-7 days and 1,3,6,and 12 months after the operation(Wald x2=30.438).Hemodynamic parameters included increased blood velocity such as PSV,EDV,TAMV,and TAPV(Waldx2 was 12.117,29.310,31.075 and 17.525,respectively)and blood flow including TAMV flow and TAPV flow(Wald x2 was 54.503 and 34.986,respectively)increased,while RI and PI values were decreased(Waldx2 was 112.568 and 103.629,respectively),and the differences were statistically significant(all P＜0.05).However,there was no significant difference in hemodynamic parameters in the non-patency group at 12 months after operation(all P＞0.05).Compared with 4-7 days after surgery,PSV(252.0[206.8,315.3]cm/s vs.102.5[84.0,119.0]cm/s)and EDV(119.5[106.3,159.8]cm/s vs.43.5[36.8,52.0]cm/s)in the non-patency group were significantly higher at the cranial entrance 12 months after surgery(both P＜0.05),but there was no significant difference in RI and PI values(both P＞0.05).Compared with 4-7 days after surgery,the blood flow parameters of STA intracranial segment,including PSV(29.4[24.8,41.4]cm/s vs.111.5[63.3,120.0]cm/s),EDV(19.7[15.2,22.2]cm/s vs.58.5[28.3,70.0]cm/s)and PI(0.55[0.42,0.63]vs.0.83[0.61,0.90])values in the non-patency group at 12 months after surgery were significantly decreased(all P＜0.05).(3)CTP parameters:the relative cerebral blood flow(rCBF)of the patency group increased at 12 and 18 months after surgery compared to preoperative levels,while relative cerebral blood volume(rCBV),relative peak time(rTTP)and relative mean transit time(rMTT)decreased,with statistical significance(all P＜0.05).At 12 and 18 months after operation,rCBF increased,while rMTT decreased in the non-patency group(both P＜0.05),but there was no significant difference as for rCBV and rTTP.The rTTP of the patency group at 12 and 1 8 months was lower than that of the non-patency group(12 months after surgery:1.14[1.06,1.15]vs.1.20[1.14,1.28],P=0.024;1 8 months after surgery:1.14[1.06,1.15]vs.1.20[1.14,1.28],P=0.023),but there was no statistical significance for other parameters between the two groups(all P＞0.05).(4)NIHSS score and prognosis:clinical follow-up results 18 months after the operation showed that no new stroke occurred during the follow-up period.The NIHSS scores in the patency group and the non-patency group were remarkably lower at 7 days,12,and 18 months after surgery than at admission(patency group:2[0,4],1[0,2],0[0,2]vs.3[0,6],respectively;the non-patency group:3[1,5],3[1,6],2[1,6]vs.4[1,7],respectively),with significant differences(all P＜0.05);However,the NIHSS scores in the patency group were significantly lower than that in the non-patency group at 12 and 18 months after surgery,and the proportion of patients with good prognosis in the patency group was substantially higher than that in the non-patency group(12months:87.1％[88/101]vs.4/8,P=0.039;18 months:90.1％[91/101]vs.4/8,P=0.025).Conclusion CDU can quantitatively evaluate the hemodynamic changes of bypass arteries after the STA-MCA bypass procedure,which can be applied to the long-term dynamic follow-up after the surgery.

Objective:To analyze the research progress of family psychological education in schizophrenia population, in order to understand the elements and current situation of family psychological education application, and provide guidance for future research in this field.Methods:According to the basic idea of scoping review, research on family psychological education for schizophrenia patients was systematically searched in PubMed, Embase, CINAHL, Web of Science, Cochrane Library, China National Knowledge Infrastructure, WanFang Data, and China Biology Medicine. The search period was from database establishment to March 15, 2023.Results:A total of 15 articles were included, including 11 completely randomized controlled trials, 2 semi-randomized controlled trials, and 2 follow-up studies. The content consisted of the evaluation and intervention forms of family psychological education, and the development and implementation of specific intervention plans.Conclusions:There is limited research on family psychological education for patients with schizophrenia, and the implementation efforts around the world are insufficient. In the future, relevant research can be conducted to develop cost-effective education programs that are in line with China's culture and environment, so that schizophrenia patients and their families can receive evidence-based treatment to improve patient and family outcomes.

The peroxisome proliferator-activated receptor gamma(peroxisome proliferator-activated receptor gamma,coactivator 1 beta,PPARGC1B)gene is an intranuclear receptor transcription fac-tor responsible for regulating the expression of target genes.To comprehend the characteristics and mutations of the PPARGC1B gene within the Sichuan yak population,the SNP loci of the PPARGC1B gene were identified through direct sequencing of PCR products.Additionally,the cod-ing region of the PPARGC1B gene was obtained via PCR amplification and sequencing.Bioinforma-tics analyses were conducted to predict protein-coding and mRNA secondary structure.This study identified four exon SNP mutation sites(E9-189A→C,E9-387G→A,E9-542C→T,and E9-554T→C)based on the single nucleotide polymorphism analysis of the PPARGC1B gene in Sichuan yaks.Notably,the E9-387G→A and E9-554T→C loci exhibited significant correlations with shear force and backfat thickness in Sichuan yaks.Subsequently,bioinformatics analysis of the four mutation sites revealed that the PPARGC1B protein is an acidic,unstable,non-transmembrane,and non-secretory hydrophilic protein with a coiled helix structure.It lacks a signal peptide and transmembrane region,predominantly functions in the nucleus,and features 106 phosphorylation sites,one glycosylation site,and one conserved RRM structure.The secondary structure comprises mainly α-helix and random coils.Although the protein structure of the PPARGC1B gene remained unchanged post-mutation,there were significant differences in mRNA secondary structure.These findings suggest that the polymorphic loci of the PPARGC1B gene in Sichuan yaks could serve as a theoretical basis for enhancing meat quality traits through molecular biological methods,presen-ting practical applications in breeding.
