The Strengths and Difficulties Questionnaire (SDQ) and Depression Anxiety and Stress Scale (DASS-21) were used to investigate preschool children s EBPs and maternal emotional symptoms, respectively.@*Results@#The detection rates of preschool children s emotional symptoms, conduct problems, hyperactivity, peer interaction problems, prosocial behavior and difficulty scores were 15.7%, 17.4%, 20.0%, 32.3%, 15.1% and 15.8%, respectively. The detection rates of mother s depression, anxiety and stress symptoms were 7.9%, 12.7% and 4.8%, respectively. Multivariate Logistic regression analysis showed that, compared with children of mothers with no depression, anxiety and stress symptoms, offspring of mothers reported depression, anxiety and stress symptoms had significantly higher risks of emotional symptoms, conduct problems, hyperactivity, peer problems and total difficulties ( OR=1.76-6.35, P <0.01). Maternal emotional symptoms had the most significant effect on children s emotional symptoms, and there was no significant correlation between maternal stress symptoms and children s prosocial behavior ( OR=1.40, P >0.05). There was no significant gender difference in the relationship between maternal emotional symptoms and children s emotional and behavioral problems ( ROR=0.73-1.07, P >0.05). For only children whose mothers reported stress symptoms showed a higher risk of emotional and behavior problems than non singleton children ( ROR=2.03, P <0.05).@*Conclusion@#Maternal emotional symptoms are related to preschool children s emotional and behavioral problems. Early identification and intervention of mother s negative emotional symptoms, are beneficial to the prevention of preschool children s emotional and behavioral problems.

Baicalin Ameliorates Corticosterone-Induced Depression by Promoting Neurodevelopment of Hippocampal via mTOR/GSK3β Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the role of hippocampal neurodevelopment in the antidepressant effect of baicalin.@*METHODS@#Forty male Institute of Cancer Research mice were divided into control, corticosterone (CORT, 40 mg/kg), CORT+baicalin-L (25 mg/kg), CORT+baicalin-H (50 mg/kg), and CORT+fluoxetine (10 mg/kg) groups according to a random number table. An animal model of depression was established by chronic CORT exposure. Behavioral tests were used to assess the reliability of depression model and the antidepressant effect of baicalin. In addition, Nissl staining and immunofluorescence were used to evaluate the effect of baicalin on hippocampal neurodevelopment in mice. The protein and mRNA expression levels of neurodevelopment-related factors were detected by Western blot analysis and real-time polymerase chain reaction, respectively.@*RESULTS@#Baicalin significantly ameliorated the depressive-like behavior of mice resulting from CORT exposure and promoted the development of dentate gyrus in hippocampus, thereby reversing the depressive-like pathological changes in hippocampal neurons caused by CORT neurotoxicity. Moreover, baicalin significantly decreased the protein and mRNA expression levels of glycogen synthase kinase 3β (GSK3β), and upregulated the expression levels of cell cycle protein D1, p-mammalian target of rapamycin (mTOR), doublecortin, and brain-derived neurotrophic factor (all P<0.01). There were no significant differences between baicalin and fluoxetine groups (P>0.05).@*CONCLUSION@#Baicalin can promote the development of hippocampal neurons via mTOR/GSK3β signaling pathway, thus protect mice against CORT-induced neurotoxicity and play an antidepressant role.

Successful treatment of CD 19 targeted chimeric antigen receptor T cells in 2 children with isolated testicular recurrence of acute B lymphoblastic leukemia and literature review / 中华实用儿科临床杂志

This study reports the diagnosis and treatment of 2 children with isolated testicular recurrence (ITR) of acute B lymphoblastic leukemia (B-ALL) treated with CD 19 targeted chimeric antigen receptor T (CD 19 CAR-T) cells in May and December 2019 in the Department of Hematology and Oncology, Children′s Hospital of Soochow University, and explores the efficacy of CD 19 CAR-T cells therapy versus conventional radiotherapy and chemotherapy through literature review.Both cases were diagnosed as B-ALL by the morphologic, immunologic, cytogenetic and molecular biology methods.ITR was diagnosed by testicular biopsy at 60 months and 38 months after initial diagnosis in 2 cases, respectively.After infusion of CD 19 CAR-T cells at 7.0×10 6/kg and 1.5×10 7/kg, respectively for 7-10 days, testicular leukemia cell infiltration disappeared and complete remission was obtained.Among them, case 2 developed cytokine release syndrome and immune effector cell-related neurotoxicity syndrome after treatment, which was improved after drug intervention.It is suggested that CD 19 CAR-T cells are effective in the treatment of ITR in children, which may be an alternative to orchiectomy or local radiotherapy for ITR in children with B-ALL.

Efficacy of Chimeric Antigen Receptor T Cell in the Treatment of Refractory/Recurrent B Acute Lymphocytic Leukemia in Children / 中国实验血液学杂志

OBJECTIVE@#To observe the efficacy of chimeric antigen receptor T cell (CAR-T) in the treatment of children with refractory/recurrent B acute lymphocytic leukemia (B-ALL).@*METHODS@#Thirty-two patients with r/r B-ALL were treated by CAR-T, the recurrence and death respectively were the end point events to evaluate the efficacy and safety of CAR-T.@*RESULTS@#The median age of the patients was 7.5 (2-17.5) years old; 40 times CAR-T were received in all patients and the median number of CAR-T was 0.9×107/kg; efficacy evaluation showed that 2 cases died before the first evaluation. Thirty patients showed that 3, 6, and 9-moth RFS was (96.3±3.6)%, (81.4±8.6)% and (65.3±12.5)%, respectively, while 3, 6, and 9-month OS was all 100%, and 12, 24-month OS was (94.7±5.1)% and (76±12.8)%. BM blasts≥36% before reinfusion and ferritin peak≥2 500 ng/ml within two weeks of CAR-T cell reinfusion were associated with recurrence. Adverse reactions mainly included cytokine release syndrome (CRS) and CART-cell-related encephalopathy syndrome (CRES), CRS appeared in 26 patients within a week of CAR-T cell reinfusion. CRES reaction was detected in 12 patients. Eighteen patients received intravenous drip of tocilizumab, among them, 12 combined with glucocorticoid. CRS and CRES reactions were relieved within one week after treatment. Hormone dosage was related to the duration of remission in patients, and the cumulative dose of methylprednisolone≥8 mg/kg showed a poor prognosis.@*CONCLUSION@#CAR-T is a safe and effective treatment for r/r B-ALL, most CRS and CRES reactions are reversible. BM blasts ≥36% before reinfusion and cumulative dose of methylprednisolone ≥8 mg/kg after reinfusion both affect the therapeutic effect. Ferritin≥2 500 ng/ml within two weeks after reinfusion is related to disease recurrence and is an independent prognostic risk factor.

Objective@#To investigate the origin of infection and risk factors of a case with SARS-CoV-2 infection associated with overseas countries in the Ningbo-Zhoushan Port, Zhejiang Province, so as to provide the evidence for improving the COVID-19 control measures at ports.@*Methods@#Ningbo Center for Disease Control and Prevention ( CDC ) and Beilun CDC conducted case finding and epidemiological surveys immediately after being informed. The general information, history of vaccination and the travel during the latest 14 days were collected from the positive case, and all close contacts were tracked. Saliva samples were collected for SARS-CoV-2 nucleic acid testing and whole-genome sequencing, and the sequencing results were aligned with the GISAID's EpiCoV database. The origin of infection and transmission route of the positive case was investigated.@*Results@#A case was identified positive for SARS-CoV-2 nucleic acid during company M's routine screening in the Ningbo-Zhoushan Port on August 10, 2021, and was confirmed positive for SARS-CoV-2 nucleic acid by Beilun CDC and Ningbo CDC on August 11. Whole-genome sequencing showed SARS-CoV-2 B.1.617.2 ( Delta ) variant, which shared the highest homology with the virus sequence uploaded by Russia on June, 2021 ( Russia/MOW-RII-MH27356S/2021 ). The case was a bundling worker for overseas container ships, and reported communicated with foreign boatmen and contacted materials without protected interventions on the SINOKOR AKITA Container Ship between August 4 and 5, 2021. This ship anchored at Vladivostok, Russia from July 27 to 29, anchored at Ningbo Harbor on August 4, and departed on August 5. Then, 11 boatmen from this ship were tested positive for SARS-CoV-2 nucleic acid on August 8. One asymptomatic case was reported in this epidemic; 254 close contacts and 617 secondary close contacts were identified, and all were tested negative for SARS-CoV-2 nucleic acid. No new cases with SARS-CoV-2 infections were detected until August 25, 2021, and the emergency response was therefore terminated.@*Conclusions@#The infection was a sporadic COVID-19 epidemic associated with overseas countries, which was caused by Delta variant infection through contacts with foreign boatmen or materials by a bundling worker in Ningbo-Zhoushan Port; fortunately, no epidemic spread occurred. Intensified closed-loop management and increased frequency of SARS-CoV-2 nucleic acid test among high-risk populations, and improving the precision and rapid emergency treatment of COVID-19 epidemics are required for the containment of COVID-19 at ports.

Risk factors for stress urinary incontinence during pregnancy and postpartum period / 中华围产医学杂志

Stress urinary incontinence (SUI) is closely related to pregnancy and delivery. With the implementation of the three-child policy and the increasing number of pregnant women at advanced age or with obesity, the prevalence of SUI during pregnancy and the postpartum period is increasing gradually. Risk factors of SUI that are associated with pregnancy and childbirth include delivery mode, advanced maternal age, overweight/obesity, macrosomia, prolonged second stage of labor, epidural anesthesia, and breastfeeding. Identification of such risk factors is crucial for early intervention for high-risk patients, which would be conducive to reducing the risk of long-term SUI.

Comparison of the characteristics of NK cells after two different methods of expansion and observation of the clinical efficacy in patients who relapsed post allogeneic hematopoietic stem cell transplantation / 中华血液学杂志

Objective: To explore the differences in the biological effects of different expansion systems on natural killer (NK) cells, as well as the safety and preliminary clinical efficacy in the treatment of patients with recurrence after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: Peripheral blood cells from healthy donors were stimulated with either CD3 combined with CD52 or K562 feeder cells loaded with IL-21/4-1BB to induce NK cell expansion. Changes in the NK cell phenotype, cytokine secretion, and cytotoxicity before and after expansion were detected. We also evaluated the safety and clinical efficacy of two different expansion strategies for patients received NK infusion. Results: Compared with the CD3/CD52 monoclonal antibody amplification system, the feeder cell expansion group had a higher purity of NK cells and higher expression ratios of NK cell surface activation receptors such as DNAM-1 and NKp30, while inhibitory receptor CTLA-4 expression was low and NKG2D/CD25/CD69/ Trail/PD-1/TIM-3/TIGIT had no statistically significant differences between the groups. Further functional results showed that the expression level of KI67 in NK cells after expansion in the two groups increased significantly, especially in the feeder cell expansion group. Simultaneously, the perforin and granzyme B levels of NK cells in the feeder cell expansion group were significantly higher than in the CD3/CD52 expansion group. A retrospective analysis of eight patients who received monoclonal antibody-expanded NK cell reinfusion and nine patients with trophoblast cell-expanded NK cell reinfusion was done. The disease characteristics of the two groups were comparable, NK cell reinfusion was safe, and there were no obvious adverse reactions. Clinical prognostic results showed that in the CD3/CD52 monoclonal antibody amplification group, the MRD conversion rate was 50% (2/4) , and the feeder cell expansion group was 50% (3/6) . After 5 years of follow-up from allo-HSCT, three patients in the monoclonal antibody expansion group had long-term survival without leukemia, and the remaining five patients had died; two patients died in the feeder cell expansion group, and the other six patients had long-term survival. Six cases had GVHD before NK cell reinfusion, and GVHD did not aggravate or even relieved after NK cell reinfusion. Conclusions: Preliminary results show that the biological characteristics of NK cells with diverse expansion strategies are significantly different, which may affect the clinical prognosis of patients with recurrence or persistent minimal residual disease after HSCT. The two groups of patients treated with NK cells from different expansion strategies had no obvious adverse reactions after NK cell infusion, but efficacy still needs to be further confirmed.

Clinical analysis of ureteral endometriosis complicated with hydronephrosis:92 cases series / 中华妇产科杂志

Objective:To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis.Methods:A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021.Results:The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before.Conclusion:Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Compared with CUMS group, sugar preference rate in FLU group ((81.90±1.19) %), BA-H group (77.86±2.51)%) and BA-L group ((67.98±2.56)%) increased ( t=24.83, 11.68, 3.00, all P<0.05). The results of water maze test showed that compared with CON group, the number of crossing platform ((6.33±0.82), (1.83±0.75), t=9.93, P<0.05) and the target quadrant residence time ((46.83±4.78)s, (24.25±6.12)s, t=7.13, P<0.05) of mice in CUMS group were decreased, but the the escape latency was prolonged ((14.88±3.00) s, (70.70±4.77) s, t=24.26, P<0.05). Compared with CUMS group, the number of crossing platform ((5.00±0.89)times, (5.17±0.75)times and (3.33±0.82) times, t=6.64, 7.67, 3.31, all P<0.05), and the residence time in the target quadrant ((36.80±2.66) s, (36.82±5.62) s, (33.28±3.56) s, t=4.61, 3.71, 3.13, all P<0.05) in FLU group, BA-H group and BA-L group increased, but the escape latencies were shortened ((23.37±4.86) s, (34.83±4.72) s, (62.15±5.30) s, t=17.02, 13.10, 2.94, all P<0.05). WB results showed that compared with CON group, the expression of ERK protein ((1.00±0.15), (0.36±0.10), t= 6.26, P<0.05) and CREB protein((1.00±0.12), (0.29±0.03), t=10.32, P<0.05) in hippocampus of mice in CUMS group decreased.Compared with CUMS group, ERK protein in hippocampus of mice in FLU, BA-H and BA-L groups increased ((0.87±0.05), (0.77±0.08), (0.67±0.03), t=8.25, 5.7, 5.39, all P<0.05), and CREB protein in FLU, BA-H and BA-L groups were also increased ((0.90±0.12), (0.84±0.14), (0.62±0.04), t=8.94, 6.59, 12.25, all P<0.05). qPCR results showed that compared with CON group, ERK mRNA ((1.00±0.03), (0.41±0.10), t=9.78, P<0.05) and CREB mRNA ((1.00±0.08), (0.61±0.12), t=4.62, P<0.05) were decreased in CUMS group.Compared with CUMS group, ERK mRNA in hippocampus of mice in FLU, BA-H and BA-L groups were increased ((0.71±0.08), (0.69±0.03), (0.59±0.04), t=4.15, 4.65, 2.84, all P<0.05), CREB mRNA in FLU group and BA-H group were increased ((0.87±0.08), (0.86±0.07), t=3.14, 3.19, all P<0.05). Conclusion:BA can improve the depression-like behavior of CUMS model mice.The mechanism of action may be related to the regulation of ERK and CREB proteins.

Effects and mechanism of Chinese medicine Jiawei Yupingfeng in a mouse model of allergic rhinitis / 中西医结合学报

OBJECTIVE@#Chinese medicine has the potential to modulate allergic rhinitis (AR). There have been studies investigating the treatment efficacy of Yupingfeng San, alone or in combination with other ingredients, in AR, though few have studied the potential mechanisms of these drugs. In the present study, we measured the effects of Jiawei Yupingfeng (JWYPF), a traditional Chinese medicine formula, on mice with ovalbumin-induced AR and explored its underlying mechanism of action.@*METHODS@#Forty BALB/c mice were randomly divided into normal control, allergy control and two treatment groups of ten mice each. In the normal control group, mice were sensitized and challenged with saline. The mice in the allergy control and treatment groups were sensitized and challenged with ovalbumin and aluminum hydroxide gel. The treatments of JWYPF and Nasonex were administered intranasally in the AR mice for one week. Several signs of allergic inflammation, such as nasal eosinophils and inflammatory cytokines, were measured to determine the underlying mechanisms.@*RESULTS@#Mice in the JWYPF and Nasonex groups had significantly lower AR symptom scores than those in the allergy control group (the mean differences between JWYPF and the allergy control, and Nasonex and the allergy control were -2.00 ± 0.35 and -2.40 ± 0.32). After treatment with JWYPF and Nasonex, the levels of ovalbumin-specific IgE and histamine were significantly reduced, as were the levels of interlukin-4 and transforming growth factor-β, while interferon-γ levels were increased (all P < 0.0001, vs. allergy control). These two treatments also significantly inhibited eosinophil and mast cell infiltration into the nasal cavity but were not statistically different from one-another.@*CONCLUSION@#JWYPF has a potential therapeutic effect on AR via adjusting the rebalance of T helper 1 and T helper 2.

Construction and strategies of disease prevention and control system in the new era in Shanghai / 上海预防医学

After the epidemic of novel Coronavirus Disease 2019(COVID-19), construction of disease prevention and control has become a top priority. As a pioneer in the recovery of global economy and society, Shanghai should play a fundamental role in building a comprehensive system of public health and advanced disease prevention and control in the new era. In this article, we systematically categorize the requirements for the construction of disease prevention and control system in the new era, identify the weakness and challenges during and after the epidemic, and then make suggestions. It is proposed that we should utilize the important window period of the"14th Five-Year Plan", with the"Healthy China"strategy and municipal"20 Tasks for Public Health Construction"as the starting point, to make substantial contribution to the functional orientation, investment of resources, capacity building, operational mechanism and team building, which may provide scientific evidence for the reform and development of disease prevention and control system.

Current financing in disease control and prevention institutions in China / 上海预防医学

Objective To analyze the current situation of financing in disease control and prevention constitutions in China, to identify existing problems, to explore potential reasons, and to make policy recommendations accordingly. Methods Financial related indicators, including revenue and expense of disease control and prevention institutions, were collected through questionnaire survey. Moreover, some disease control and prevention institutions were selected for on-site survey. Results The proportion of public health institutions in the Total Health Expenditure had fallen from 7.0% in 2014 to 5.6% in 2018. The proportion of financial compensation in the operation of disease control and prevention institutions was less than 50%. The gap between revenue and expenditure had not been covered completely after the cancellation of three categories of administrative charges. In addition, financing mechanism of public health service funds remained unclear. Conclusion We recommend the strategies, including optimizing financing structure, increasing investment in disease control and prevention, increasing the level of financial guarantee, improving the mechanism of public health service funds, and multi-channel financing.
