OBJECTIVETo research on the protective effect of 3'-methoxy-puerarin (3'-mo-pue) on rat brain suffering from ischemia and to offer the experimental basis for widening the applied areas of Radix Puerariae.

METHODAll rats were randomly divided into sham operation group, control group, Pue group and 3'-mo-pue group. The influence of different dosage on relevant indexes were measured through cerebral artery occlusion (MCAO) model rat covered by Fecl3, and cerebral ischemia-reperfusion model rat after 2VO.

RESULTThe result showed that 3'-mo-Pue could reduce the scores of neurological deficit, cerebral infarcted zone to varying degrees and the water content of brain tissue in MCAO model. It could obviously increase the activity of CAT and GPx in the hippocampus and also increase the activity of CAT and GPx in the cortex in the ischemia field. Moreover, 3'-mo-Pue could decrease the content of LPO, LD in the brain tissue of cerebral ischemia-reperfusion model rat.

CONCLUSION3'-mo-Pue has favorable protective effect on brain suffering from ischemia. The mechanism is possibly related to its effect of anti-oxidation.

OBJECTIVETo study the difference and similarity between Hans and Uighurs in regard to Rhesus box and its significance.

METHODSThe sequence specific primers of upstream, downstream and hybrid Rhesus boxes were designed on the basis of RHD gene sequence. The upstream, downstream and hybrid Rhesus boxes were determined by polymerase chain reaction-sequence specific primer(PCP-SSP) and mismatched PCR.

RESULTSThe percentage of RHD-/RHD-, RHD+/RHD- and RHD+/RHD+ genotypes ascertained in the unrelated Hans with RhD(-) were 61.40%, 34.21% and 4.39% respectively, while those in the unrelated Chinese Uighurs with RhD(-) were 94.44%, 2.78% and 2.78% respectively. Furthermore, all 6 cases of some other minorities were RHD-/RHD- types. The percentage of RHD-/RHD- and RHD+/RHD- genotypes ascertained in the unrelated Chinese Uighurs were significantly higher than those in Chinese Hans (P < 0.01), whereas no statistically significant difference in the percentage of RHD+/RDH+ genotype between the two groups was observed (P > 0.05).

CONCLUSIONThe Rh blood group of Uighurs in Xingjiang possesses both Oriental and Caucasian characteristics, which embodies a special ethnical aspect of the Chinese nation and is in accord with the anthropologic research results.

OBJECTIVES: To explore the risk factors for hemorrhagic cystitis (HC) in children with β-thalassemia major (TM) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: A retrospective analysis was conducted on clinical data of 247 children with TM who underwent allo-HSCT at Shenzhen Children's Hospital from January 2021 to November 2022. The children were divided into an HC group (91 cases) and a non-HC group (156 cases) based on whether HC occurred after operation. Multivariable logistic regression analysis was used to explore the risk factors for HC, and the receiver operating characteristic curve was used to analyze the predictive efficacy of related factors for HC. RESULTS: Among the 247 TM patients who underwent allo-HSCT, the incidence of HC was 36.8% (91/247). Univariate analysis showed age, incompatible blood types between donors and recipients, occurrence of acute graft-versus-host disease (aGVHD), positive urine BK virus deoxyribonucleic acid (BKV-DNA), and ≥2 viral infections were associated with the development of HC after allo-HSCT (P<0.05). Multivariable analysis revealed that incompatible blood types between donors and recipients (OR=3.171, 95%CI: 1.538-6.539), occurrence of aGVHD (OR=2.581, 95%CI: 1.125-5.918), and positive urine BKV-DNA (OR=21.878, 95%CI: 9.633-49.687) were independent risk factors for HC in children with TM who underwent allo-HSCT. The receiver operating characteristic curve analysis showed that positive urine BKV-DNA alone or in combination with two other risk factors (occurrence of aGVHD, incompatible blood types between donors and recipients) had a certain accuracy in predicting the development of HC after allo-HSCT (area under the curve >0.8, P<0.05). CONCLUSIONS Incompatible blood types between donors and recipients, occurrence of aGVHD, and positive urine BKV-DNA are risk factors for HC after allo-HSCT in children with TM. Regular monitoring of urine BKV-DNA has a positive significance for early diagnosis and treatment of HC.

BACKGROUNDThe 2009 pandemic H1N1 (pH1N1) influenza showed that relatively young adults accounted for the highest rates of hospital admission and death. In preparation for pH1N1, the aim of the study is to identify factors associated with the mortality of patients with 2009 pH1N1 infection, especially for young patients without chronic medical conditions.

METHODSRetrospective observational study of 2151 severe or critical adult cases (≥ 14 years old) admitted to a hospital with pH1N1 influenza from September 1, 2009 to December 31, 2009 from 426 hospitals of 27 Chinese provinces. A confirmed case was a person whose pH1N1 virus infection was verified by real-time reverse-transcriptase polymerase chain reaction (rRT-PCR). Severe and critical cases were defined according to the H1N1 2009 Clinical guidelines (Third Edition, 2009) released by the Ministry of Health of China.

RESULTSAmong the 2151 patients, the mean age was 34.0 years. Two hundred and ninty-three (13.6%) died during hospital stay. One thousand four hundred and forty-two patients (67.0%) had no comorbidities and 189 (13.1%) of them died. Pregnancy (OR 8.03), pneumonia (OR 8.91), dyspnea (OR 3.95), central nervous system (CNS) symptom (OR 1.55), higher APACHE (Acute Physiology and Chronic Health Evaluation) II score (OR 1.06), Alanine aminotransferase (ALT) (OR 1.002), and the lactate dehydrogenase (LDH) level (OR 1.001) were independent risk factors for death among adults without chronic medical conditions. Higher APACHE II score (OR 1.08) and age (OR 1.06) were independent risk factors for death among adults with respiratory diseases. A multivariate analysis showed an association between mortality and CNS symptoms (OR 2.66), higher APACHE II score (OR 1.03), ALT (OR 1.006), and LDH level (OR 1.002) in patients with cardiovascular diseases. Dyspnea (OR 11.32) was an independent risk factor for patient death in patients with diabetes mellitus.

CONCLUSIONClinical knowledge of identified prognostic factors for mortality may aid in the management of adult influenza infection.

Objective To understand the epidemic situation and the source of infection of the reemerge human rabies in Qinghai. Methods We collected the data on human rabies and the data on the cases of multi- victims bitten by the identical dog, and also the laboratory data of the nucleoprotein ( N) gene of rabies virus from the samples which were detected by reverse transcription-polymerase chain reaction (RT-PCR) and direct immunofluorescence assay (DFA) from 2012 to 2017, to describe the epidemiological characteristics of human rabies and the prevalence of rabies virus in host animals, and to explore the source of infection of reemerge human rabies. Results A total of 7 human cases were reported in 2012-2017 in Qinghai province, among which 1 was bitted by wolf, 2 were bitted by stray dogs, 3 were bitted by domestic dogs which injured by stray dogs or wolfs. A total of 892 canine brain tissue samples were collected, from which 46 positive samples were detected with the positive rate of 5.16% (95% CI：3.70%-6.61%). The positive samples were collected from the nomadic region, which were consistent had the location of the human rabies. The samples collected from the cases of multi-victims bitten by the identical dog/animal had the positive rate of 73.08%, and 4 out of 7 human rabies were exposed to the cases of multi-victims bitten by the identical dog/animal. Genetic sequencing of the rabies virus detected from canine brain tissue samples were belong to China IV lineage, which was closely related to the Arctic clade. Conclusions The reemerging rabies happened in nomadic region of Qinghai province could be a consequence of spillover from wildlife especially from wolfs. The better surveillance system covering the human, livestock and wildlife should be set up to mitigate the rabies virus spread from the wildlife.

BACKGROUNDUnregulated commercial blood/plasma collection among farmers occurred between 1992 and 1995 in central China and caused the second major epidemic of human immunodeficiency virus type 1 (HIV-1) infection in China. It is important to characterize HIV-1-infected former blood donors and to study characteristics associated with disease progression for future clinical intervention and vaccine development.

METHODSA cross-sectional study was performed on HIV-1-infected former blood donors (FBDs) and age-matched HIV-seronegative local residents. Demographic, epidemiologic, clinical and key laboratory data were collected from all study participants. Both unadjusted and adjusted multivariate linear regressions were employed to analyze the association of the decrease of CD4(+) T-cell counts with other characteristics.

RESULTSTwo hundred and ninety-four HIV-1-infected FBDs and 59 age-matched HIV-seronegative local residents were enrolled in this study. The unregulated blood/plasma collection occurred more than a decade (10.8 - 12.8 years) ago, which caused the rapid spread of HIV-1 infection and the high prevalence of co-infection with hepatitis C virus (HCV, 89.5%); hepatitis B virus (HBV) co-infection was observed in only 11 HIV(+)participants (3.7%). Deterioration in both clinical manifestation and laboratory parameters and increase of viral loads were observed in parallel with the decrease of CD4(+) T-cell counts. The decrease of total lymphocyte counts (P < 0.001) and hemoglobin levels (P < 0.001) and the appearance of dermatosis (P = 0.03) were observed in parallel with the decrease of CD4(+) T-cell counts whereas viral loads (P < 0.001) and CD8(+) T-cell counts (P = 0.01) were inversely associated with CD4(+) T-cell counts.

CONCLUSIONSCo-infection with HCV but not HBV is highly prevalent among HIV-1-infected FBDs. CD4(+) T-cell counts is a reliable indicator for disease progression among FBDs. Total lymphocyte counts, hemoglobin level and appearance of dermatosis were positively associated with CD8(+) T-cell counts and viral loads were inversely associated with the decreased CD4(+) T-cell counts.
