Objective:To explore the clinical and genetic characteristics and follow-up status of pediatric patients with hepatic glycogen storage disease in order to further improve the prognosis.Methods:The clinical data of hospitalized children diagnosed with hepatic glycogen storage disease in the Department of Gastroenterology at the Children's Hospital of Capital Institute of Pediatrics from January 2010 to April 2023 were collected and retrospectively analyzed. The results of laboratory examination and gene sequencing were analyzed, and the number of cases that exceeded three (n) were grouped according to the genetic results: Group 1 was type Ⅰ ( n=8), Group 2 was type Ⅲ ( n=5), and Group 3 was type Ⅸa ( n=8).The growth, development and prognosis of the children were followed up. The related clinical characteristics of pediatric hepatic glycogen storage disease were summarized. Results:Twenty-five pediatric patients with hepatic glycogen storage disease were enrolled in this study, with fifteen males and ten females. The mean age of diagnosis was (29.1±13.5) months. There were twelve cases (48%) accompanied with varying degrees of hypoglycemia, and two cases (8%) with severe hypoglycemia.There were nineteen cases with stature retardation (76%), four cases with anemia (16%), three cases with proteinuria (12%), and one case with cholestasis (4%).The genetic results showed that there were four cases of type Ⅰa (16%), four cases of type Ⅰb (16%), one case of type Ⅱ (4%), five cases of type Ⅲ (20%), two cases of type Ⅳ (8%), one case of type Ⅵ (4%), and eight cases of type Ⅸ (32%).The three subgroups analysis showed that there were significant statistical differences in uric acid and triglycerides among the three groups ( P<0.05), while there were no statistical significant differences in transaminase levels, fasting blood glucose, lactate, cholesterol, and low-density lipoprotein levels ( P>0.05). The height-for-age Z scores of the three groups were -2.86±1.62, -1.46±1.06, and -1.83±0.98, respectively. The growth and development of groups 2 and 3 were significantly improved compared with group 1 ( P<0.05), with Z scores of -2.28±1.07, 0.20±1.54, and 0.10±1.44 after at least one year of follow-up. All pediatric patients with type Ⅸa had discontinued using raw corn starch after more than one year of follow-up and their transaminases had returned to normal. Four pediatric patients with type Ia were orally administered raw corn starch on a regular basis, and the aminotransferases, uric acid, and lactate were normal, with hypoglycemia being monitored. Among the four cases with type Ⅰb, one had recurrent respiratory tract and intestinal infections, two were combined with Crohn's disease, and one was monitored for hypoglycemia. In four cases of type Ⅲ, raw corn starch was discontinued, and a high-protein, low-carbohydrate diet was adopted, with the exception of the presence of high creatine kinase and normal aminotransferase. Liver failure resulted in the death of one type Ⅵ case, while two were type Ⅳ cases; one died, and one case recently had slightly elevated aminotransferase. Conclusion:When pediatric patients exhibit manifestations such as hepatomegaly, elevated transaminases, fasting hypoglycemia, and delayed growth and development, it is necessary to be alert to hepatic glycogen storage disease. Clinical manifestations and biochemical indicators combined with genetic testing are helpful for the diagnosis of hepatic glycogen storage disease. Simultaneously, targeted nutritional management should be carried out according to the metabolic characteristics of different subtypes, with attention on growth and development status.

Objective:To evaluate the effectiveness of entrustable professional activities (EPAs) in the general practice internship of undergraduate clinical medicine students, identify issues that need improvement in the internship, and enhance medical students' competence.Methods:A total of 75 students in the five-year (English class) clinical medicine program enrolled in 2018 and 2019 who participated in general practice internship in Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October 2021 to October 2023 were selected as study subjects. The design of core EPAs was adopted to assess the correlation among different EPA dimensions and to analyze the qualified rates.Results:The evaluation of EPAs showed that EPA2 (practicing respect, understanding and teamwork) had the highest mean score of 9.33, and EPA10 (chronic disease management and management of key populations) had the lowest mean score of 8.08. A supervision level of 3a and above was used as the criterion for qualification. The supervision levels of the students' EPAs were mostly concentrated at levels 3a and 3b. The highest qualified rate was for EPA2 (practicing respect, understanding and teamwork) at 85.33%, followed by EPA1 (complying with the rules of the profession and demonstrating professionalism) at 80.00% and EPA8 (reviewing information and solving clinical problems) at 72.00%. The lowest qualified rate was for EPA10 (chronic disease management and management of key populations) at 33.33%, followed by EPA4 (analyzing and interpreting test results) at 57.33%.Conclusions:EPAs concretize competency evaluation, which can effectively reflect the "competency-oriented" training objectives encompassing multiple elements such as knowledge, skills, values, and attitudes, while maintaining professional specificity. Undergraduates demonstrated strengths in professionalism and academics, but showed deficiencies in community chronic disease management and management of key populations. These findings suggest the need to strengthen the training in health and social care to better align with the competencies required during standardized residency training.

Objective To evaluate the effect of LEARNS[listen(L),establish(E),adopt(A),reinforce(R),name(N),strengthen(S)]model health education for patients with peripherally inserted central catheter(PICC)after discharge.Methods From June 2020 to June 2021,193 discharged patients with PICC were selected as the study objects.They were divided into observation group(95 cases)and control group(98 cases)according to random number table method.The control group received routine health education and continued follow-up for 3 months.In the observation group,health education was constructed and implemented at 2,4,8 and 12 weeks after discharge based on the control group and the basis of LEARNS model.The incidence of PICC-related complications and PICC-related adverse events were compared between the two groups,and self-management ability was evaluated using cancer patients PICC self-management scale(CPPSMS)score,strategies used by people to promote health(SUPPH)were used to evaluate self-efficacy.Results The incidence of PICC-related complications and adverse events in the observation group were significantly lower than those in the control group[11.58%(11/95)vs.40.82%(40/98)and 6.32%(6/95)vs.22.45%(22/98),both P＜0.05].There were no statistically significant differences in CPPSMS scores(daily catheter observation,maintenance compliance,management confidence,anomaly handling,information acquisition,tubeed exercise,and tubeed daily life)and SUPPH scores(positive attitude,self-stress reduction,and self-decision-making)in the two groups before intervention,and the above scores were higher than those before intervention.After intervention,the above scores in the observation group were significantly higher than those in the control group(CPPSMS total score was 131.37±27.20 vs.92.41±23.89,daily catheter observation score was 26.02±6.04 vs.18.27±5.43,maintenance compliance score was 18.45±4.36 vs.13.28±3.12,and management confidence score was 17.69±3.37 vs.13.81±3.65,anomaly processing score was 15.01±3.46 vs.10.25±2.74,information acquisition score was 11.98±2.56 vs.7.84±2.07,tube motion score was 15.94±3.46 vs.10.28±2.78,daily life with tubes score was 26.28±5.19 vs.18.68±4.46,all P＜0.05;SUPPH total score was 106.54±20.84 vs.93.93±18.50,positive attitude score was 56.89±11.45 vs.49.34±10.56,self-stress reduction score was 38.25±8.73 vs.34.76±6.28,the self-decision-making score was 11.40±2.57 vs.9.83±2.96,all P＜0.05).Conclusion The implementation of health education based on LEARNS model in discharged patients with PICC tube can improve their self-management ability and self-efficacy,and improve clinical prognosis.

Objective To study the effect and mechanism of endoplamic reticulum stress on the auditory cortex injury after focal cerebral ischemia-reperfusion injury in rats.Methods 30 healthy male adult SD rats were chosen and randomly divided into 2 groups,ischemia-reperfusion(I/R) group and sham operated control,with each group 15 rats.The rats in I/R group were operated for suture-occluded method to establish middle cerebral artery occlusionmodel(MCAO),with ischemia for 60 mins followed by reperfusion for 24 h.And the control group was only to be isolated cervical vessels,with no thread embolism inserted.The auditory brainstem response (ABR) was tested before operation and at 24 h post-operation respectively.The neurological deficits,ratio of infarct volume were evaluated.The pathological changes were observed by HE.Neurocyte apoptosis were observed by Tunel,and the AI were determined.The expression of GRP78,Caspase-12 were detected by immunohistochemistry and Western blotting.Results Compared with the sham group,the neurological function scores,the infarct volume of brain of I/R group increased significantly.The threshold of ABR elevated significantly and AI rised in I/R group.HE staining showed that the neurons in the sham group were arranged in order,the shape was normal,but in the I/R group the normal structure disappeared,the nuclei were condensed.The expression of GRP78,Caspase-12 protein were significantly up-regulated.All of the differences above have statistical significance(P＜0.05).Conclusion The mechanism of hearing loss after focal cerebral ischemia-reperfusion injury in rats is perhaps related to endoplamic reticulum stress,and GRP78,Caspase-12 participate in the process of neuron apoptosis on auditory cortex caused by ERS.

Objective To study the mechanism of endoplamic reticulum stress(ERS)pretreatment induced by 2-DG on the auditory cortex injury after focal cerebral ischemia-reperfusion injury in rats. Methods The SD rats were randomly divided into 3 groups,sham group,I/R group,and ERS pretreatment group. Tread occlusion was used to prepare the model of MCAO in the mice for 60 min followed by reperfusion for 24 h. Neurological assessment was exercised and brain infarction volume was evaluated. The auditory brainstem response was tested. The pathological changes were observed by HE staining. Neurocyte apoptosis was observed by Tunel ,and the apop-tosis index(AI)was determined. Expression of GRP78 and Caspase-12 were detected by immunohistochemistry. Results Compared with the sham group,the neurological scores,ratio of infarct volume and the hearing thresh-olds in I/R group increased significantly. HE staining showed the normal structure disappeared ,and apoptotic index increased significantly. Expression of GRP78 and Caspase-12 protein significantly up-regulated. Compared with I/R group,the indicators above showed improvement to some degrees. Conclusions The ERS pretreatment can alleviate the ischemia-reperfusion injury and neuron apoptosis in auditory cortex ,and reduce the possibility of hearing loss.

Acute myocardial infarction (AMI) remains a leading cause of morbidity and mortality worldwide. The exploration of new biomarkers with high sensitivity and specificity for early diagnosis of AMI therefore becomes one of the primary task. In the current study, we aim to detect whether there is any heart specific long noncoding RNA (lncRNA) releasing into the circulation during AMI, and explore its function in the neonatal rat cardiac myocytes injury induced by H2O2. Our results revealed that the cardiac-specific lncRNA MHRT (Myosin Heavy Chain Associated RNA Transcripts) was significantly elevated in the blood from AMI patients compared with the healthy control (*p<0.05). Using an in vitro neonatal rat cardiac myocytes injury model, we demonstrated that lncRNA MHRT was upregulated in the cardiac myocytes after treatment with hydrogen peroxide (H2O2) via real-time RT-PCR (qRT-PCR). Furthermore, we knockdowned the MHRT gene by siRNA to confirm its roles in the H2O2-induced cardiac cell apoptosis, and found that knockdown of MHRT led to significant more apoptotic cells than the non-target control (**p<0.01), indicating that the lncRNA MHRT is a protective factor for cardiomyocyte and the plasma concentration of MHRT may serve as a biomarker for myocardial infarction diagnosis in humans AMI.

In recent years , there are increasing articles concerning Epstein-Barr virus associated lymphoproliferative disorder (EBV+LPD), and the name of EBV +LPD is used widely.However,the meaning of EBV+LPD used is not the same , which triggered confusion of the understanding and obstacles of the communication.In order to solve this problem.Literature was reviewed with combination of our cases to clarify the concept of EBV +LPD and to expound our understanding about it .In general, it is currently accepted that EBV +LPD refers to a spectrum of lymphoid tissue diseases with EBV infection , including hyperplasia , borderline lesions , and neoplastic diseases .According to this concept , EBV+LPD should not include infectious mononucleosis ( IM ) and severe acute EBV infection ( EBV +hemophagocytic lymphohistiocytosis, fatal IM, fulminant IM, fulminant T-cell LPD), and should not include the explicitly named EBV+lymphomas ( such as extranodal NK/T cell lymphoma , aggressive NK cell leukemia , Burkitt lymphoma, and Hodgkin lymphoma , etc.) either.EBV +LPD should currently include: ( 1 ) EBV +B cell-LPD:lymphomatoid granulomatosis , EBV +immunodeficiency related LPD , chronic active EBV infection-B cell type, senile EBV +LPD, etc.(2) EBV +T/NK cell-LPD:CAEBV-T/NK cell type, hydroa vacciniforme, hypersensitivity of mosquito bite, etc.In addition, EBV+LPD is classified, based on the disease process , pathological and molecular data , as 3 grades:grade1, hyperplasia ( polymorphic lesions with polyclonal cells ); grade 2, borderline ( polymorphic lesions with clonality ); grade 3, neoplasm (monomorphic lesions with clonality).There are overlaps between EBV +LPD and typical hyperplasia, as well as EBV+LPD and typical lymphomas .However , the most important tasks are clinical vigilance , early identification of potential severe complications , and treating the patients in a timely manner to avoid serious complications , as well as the active treatment to save lives when the complications happened .

OBJECTIVE: To investigate the effective method in treatment of pediatric chronic sinusitis. METHOD: Two hundred and ten children were clinically diagnosed as chronic sinusitis and randomly divided into three groups as pulmicort, rhinocort and routine treatment group, respectively. All the patients in different group were systemic treated by corresponding method for two weeks. RESULT: The effective rates were 84% for pulmicort treatment group, 61% for rhinocort treatment group and 48% for routine treatment group, so the effective rate for the patients treated with pulmicort were significantly higher than that with either rhinocort or routine treatment. CONCLUSION Pulmicort can be used to treat pediatric chronic sinusitis with higher effective rate.
