Objective To explore the effects of standardized environmental enrichment(EE)on cognitive function and serum brain-derived neurotrophic factor(BDNF)levels in patients with post-stroke dementia.Methods A prospective study was conducted,including 80 patients with post-stroke dementia admitted to Department of Traditional Chinese Medicine Rehabilitation,910th Hospital of the Joint Logistics Support Force of Chinese PLA from January 2021 to May 2023.Patients were randomly divided into control group,cognitive training(COG)group,aerobic exercise training(AE)group and environmental enrichment(EE)group,with 20 cases in each group.All patients received routine treatment,with COG group receiving additional cognitive function training(30 minutes each time),AE group receiving additional aerobic exercise training(30 minutes each time),and EE group receiving both aerobic exercise and cognitive function training(15 minutes of aerobic exercise training and 15 minutes of cognitive training each time).The training was conducted once a day,5 days a week,for a total of 8 weeks.The patients'mini-mental state scale(MMSE),modified Barthel index(MBI),Hamilton depression scale(HAMD),stroke-specific quality of life(SS-QOL)score and serum levels of BDNF were assessed before treatment,at 4 weeks and 8 weeks of treatment,respectively.Results Before treatment,there were no significant differences in general information,MMSE,MBI,HAMD,SS-QOL scores,and serum levels of BDNF among the four groups(P＞0.05).After 4 and 8 weeks of treatment,the above indicators of the four groups were improved compared with those before treatment,with all differences being statistically significant(P＜0.05).Inter-group comparison showed that after 4 and 8 weeks of treatment,MMSE,MBI,SS-QOL scores,and serum BDNF levels in COG,AE and EE groups were significantly higher than those in control group,and HAMD scores were significantly lower than those in control group(P＜0.05).In addition,MMSE,MBI,SS-QOL scores and BDNF levels of group EE were better than those of other 3 groups,while HAMD scores were lower than those of other 3 groups,with all differences being statistically significant(P＜0.05).There was no significant difference in above outcome indicators between COG group and AE group after 4 and 8 weeks of treatment(P＞0.05).Conclusion Standardized enrichment environment can significantly enhance cognitive function,daily living abilities of post-stroke dementia patients,alleviate depression symptoms,and improve the quality of life,which may be related to the increase in serum BDNF levels.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

OBJECTIVE: Mental disorders of the elderly population in China deserve attention. Social health is significantly associated with depression. This study aimed to evaluate the rate of depressive symptoms and to test the relationships between social health and depressive symptoms among a large sample of community-dwelling elderly adults. METHODS: We conducted a cross-sectional study among community-dwelling adults aged 60 years or above in Zhejiang Province, China. Face-to-face interviews were used to complete a structured questionnaire for all participants. We used the Social Health Scale for the Elderly (SHSE) to evaluate social health status and used the short form of the Geriatric Depression Scale to evaluate depressive symptoms. Multivariate logistic regression was used to evaluate the association between social health status and depressive symptoms. RESULTS: Of the total of 3757 participants included, 1887 (50.23%) were female, and the mean±standard deviation (SD) age was (70.0±8.3) years. The rate of depressive symptoms was 25.92%. The social health score was higher in non-depressed participants than in depressed participants (raw score 50.7 vs. 48.3, P<0.001). Participants with "moderate" or "good" social health had a significantly lower risk of depressive symptoms than those with "poor" social health (odds ratio (OR)=0.55, 95% confidence interval (CI): 0.46-0.66 for moderate social health; OR=0.45, 95% CI: 0.35-0.60 for good social health). The association between social health and depressive symptoms was consistent across several subgroups. CONCLUSIONS Social health is significantly inversely associated with depressive symptoms. The SHSE may serve as an efficient screener to identify those elderly adults with social health deficits, but systematic assessment to guide intervention merits further investigation.

Objective To study the relationship among rs505802 in SLC22A12,rs6855911,rs737267,rs12498742, rs7442295, rs734553, rs16890979 in SLC2A9 genetic polymorphisms and hypouricemia in Ningxia.Methods 6 056 subjects were collected by multistage,stratified random cluster sampling method in October and November in 2011 in Ningxia Hui autonomous region, 98 subjects with hypouricemia were selected.According to gender and age,84 controls were selected.Physical examination and laboratory biochemical index test were conducted for the study population.T test was used to compare general clinical data and biochemical indexs between two groups. SNPs were detected by Sequenom Mass ARRAY technology.By x2test,we compared the frequencies of the geno-type and allele in each group.Samples representativeness was confirmed through the Hardy-Weinberg inspection. Results The levels of TC, LDLC, and Cr in the patients were lower than those in the control group(P<0.05). There were significant differences in the distribution of A,G allele frequencies of SLC2A9 gene rs7442295 between two groups.The risk of hypouricemia in patients with A/A genotype was lower than that of A/G genotype(Pc<0.05),indicating that A>G mutation was associated with hypouricemia.Conclusions Polymorphisms of SLC2A9 gene rs7442295 are significantly correlated with hyporuricemia in Ningxia.

OBJECTIVETo analyze chromosome aberration in a child with mental retardation and abnormalities and its parents.

METHODSChromosome G banding, multiplex ligation-dependent probe amplification, fluorescence in situ hybridization and single nucleotide polymorphisms array were employed for analysis.

RESULTSKaryotype analysis revealed that the child was 46,XX and the father was 46,XY, while the mother was 46,XX, add (12)(p13). Subtelomeric region analysis with MLPA displayed that the child has reduced ACP1 gene copy number in 2p25 region and increased SLC6A12,KDM5A gene copy numbers in 12p11 region. SNP-array has fine mapped the duplication to 12p13.33-p12.3, a 15.142 Mb region, and a deletion to 2p25.3 for 3.194 Mb, which resulted in duplication of 9 genes including SLC6A12 as well as deletion of 11 genes including SNTG2, respectively. FISH analysis revealed that the child was 46,XX,ish,der(2),t(2;12)(p25;p13)mat, or partial monosomy 2p25 and partial trisomy 12p13. In addition,the mother was a carrier with cryptic balanced translocation chromosome, 46,XX,isht(2;12) (p25;p13). Mental abnormalities and retardation of the child may be attributed to heterozygous deletion of SNTG2, MYT1L genes and duplication of SLC6A12 gene.

CONCLUSIONCombined use of MLPA, FISH and SNP-array can facilitate accurate diagnosis of cryptic rearrangement at genomic level.

OBJECTIVETo observe the anti-virus effects of andrographolide (AD) on the retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs) signaling pathway when immunological cells were infected with H1N1.

METHODSLeukomonocyte was obtained from umbilical cord blood by Ficoll density gradient centrifugation, and immunological cells were harvested after cytokines stimulation. Virus infected cell model was established by H1N1 co-cultured with normal human bronchial epithelial cell line (16HBE). The optimal concentration of AD was defined by methyl-thiazolyl-tetrazolium (MTT) assay. After the virus infected cell model was established, AD was added into the medium as a treatment intervention. After 24-h co-culture, cell supernatant was collected for interferon gamma (IFN-γ) and interleukin-4 (IL-4) enzyme-linked immunosorbent assay (ELISA) detection while immunological cells for real-time polymerase chain reaction (RT-PCR).

RESULTSThe optimal concentration of AD for anti-virus effect was 250 μg/mL. IL-4 and IFN-γ in the supernatant and mRNA levels in RLRs pathway increased when cells was infected by virus, RIG-I, IFN-β promoter stimulator-1 (IPS-1), interferon regulatory factor (IRF)-7, IRF-3 and nuclear transcription factor κB (NF-κB) mRNA levels increased significantly (P<0.05). When AD was added into co-culture medium, the levels of IL-4 and IFN-γ were lower than those in the non-interference groups and the mRNA expression levels decreased, RIG-I, IPS-1, IRF-7, IRF-3 and NF-κB decreased significantly in each group with significant statistic differences (P<0.05).

CONCLUSIONSThe RLRs mediated viral recognition provided a potential molecular target for acute viral infections and andrographolide could ameliorate H1N1 virus-induced cell mortality. And the antiviral effects might be related to its inhibition of viral-induced activation of the RLRs signaling pathway.

OBJECTIVETo study the therapeutic efficacy of manipulative reduction and percutaneous pin fixation for the treatment of severely displaced distal tibial fractures in children.

METHODSFrom May 2009 to December 2012,56 children with severely displaced distal tibial fractures were analyzed, who had been treated with manipulative reduction and percutaneous pin fixation. Preoperative fractures were confirmed as severely displaced fractures by X-ray apparatus. There were 33 boys and 23 girls,ranging in age from 3 to 14 years, with an average of 10.1 years. All the fractures were closed without vascular or nerve injuries. According to the bone fracture type, under C-arm fluoroscopy, functional reduction was achieved by manipulative reduction. The fractures were fixed with percutaneous pins. Postoperative X-ray confirmed the functional reduction. Follow-up indexes were recorded: intra-operative and postoperative complications,postoperative radiographic examination, lower extremity length and range of ankle motion. Ankle score system of Teeny was used to evaluate ankle function.

RESULTSAll the patients were followed up, and the duration ranged from 3 to 46 months, with an average duration of 19.4 months. According to the Teeny score standard, 35 patients got an excellent result, 7 good and 3 fair. Pin track reaction was found in 4 cases. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. All the patients could participate in the normal physical activities, having a normal range of motion and excellent strength of the ankle joint.

CONCLUSIONThe method of manipulative reduction and percutaneous pin fixation is a safe and convenient treatment for severely displaced distal tibial fractures in children. It has several advantages as follow: micro-trauma, tiny tissue damage, firm fixation, and the patients can exercise the function of ankle early, suggesting that it is an effective treatment method.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

OBJECTIVETo recognize the importance of analyzing the result of immunohistochemical staining correctly.

METHODReview of the three misdiagnosed cases lymphoma and exploring the causes of misdiagnosis through reviewing their clinics, histopathology and immunohistochemistry.

RESULTSCase 1 of lymphocyte rich classical Hodgkin's lymphoma (LRCHL) was misdiagnosed as follicular lymphoma (FL) initially, the RS cells were overlooked morphologically and wrongly determined BCL-2 and CD20-positive cells as tumor cells immunohistochemically; also once misdiagnosed as nodular lymphocyte predominant Hodgkin's lymphoma (NLPHL) because the CD20-negative RS misjudged cells as the positives. Case 2 of AML tumor cells expressed TdT, CD7 and CD43 unspecifically, which misdiagnosed as T-cell lymphoblastic lymphoma (T-LBL). Case 3 of type B1 thymoma was misdiagnosed as T-LBL, because CK wasn't expressed satisfactorily resulting in neglecting neoplastic epithelial cells, and lymphocytes in the background were TdT and CD99-positive.

CONCLUSIONThe diagnosis of lymphoma should be based on morphology, immunohistochemistry, clinics, and genetics. Moreover, the correct judgment of immunohistochemical staining is essential to make right diagnosis.
