AIM: To observe clinical curative efficacy about Fushu Granule(Radix Angelicae Sinensis,Pollen Typhae,etc.) on extravasated-blood diseases such as women's lochia can't go or go but can't end,abdominal pain,menoxenia,dysmenorrhoea and amenorrhoea. METHODS: 400 cases were divided into two groups.250 cases of which were treated with Fushu Cranule and remaining 150 cases were treated with Motherwort Paste.A course of treatment was seven days for both. RESULTS: The effective rate of the treatment group was(92.8%),and the control one was(82.0%).Compared with the two groups,the difference was quite distinct(P

AIM: To investigate the influence of Ginkgo biloba extract (EGb761) on c-jun expressions and motoneurons survival following root avulsion. METHODS: One hundred and eighty adult Sprague-Dawley female rats were randomly divided into control and EGb761 groups. Immediately after avulsion of C5-T1 nerve roots, the rats were injected ip with either 1 mL of EGb761 25 mg?kg~(-1)?d~(-1) or the same volume of normal saline, and the treatment repeated everyday. At 4 h to 6 weeks following avulsion, the C7 spinal segments of all rats were collected and prepared for c-jun immunocytochemistry and neutral red stain. The numbers of (c-jun) positive and survival motoneurons were counted and compared between two groups at each time point. RESULTS: In control rats following avulsion, c-jun positive motoneurons appeared at 4 h, reached its maximum at 1 d and declined to 2 weeks. Avulsion-induced motoneurons death started at 2 weeks, climbed to its maximum at 4 weeks-6 weeks. In EGb761 treated rats, both numbers of c-jun positive and survival motoneurons were more than that in control group at each time point. CONCLUSION: EGb761 attenuates avulsion-induced motoneurons death, and this effect may be related to up-regulation of c-jun gene in avulsed motoneurons. [

AIM: To investigate the influence of EGb761 on NOS expression and survival of motoneurons after spinal root avulsion.METHODS: Eighty adult SD female rats were randomly divided into control and EGb761 groups. The C5-T1 nerve roots of right brachial plexus were avulsed and injection of 1 mL of either EGb761 25 mg?kg -1 ?d -1 or normal saline (ip) was performed everyday. The treated rats were killed 1 week, 2 weeks, 4 weeks and 6 weeks following avulsion. The cryostat sections of C7 segment of every rat were collected and carried with NADPH-d histochemistry plus neutral red counterstain. The difference of the numbers of both NOS-positive and survival motoneurons were quantitatively studied. RESULTS: Following avulsion, NOS was expressed in avulsed motoneurons at 1 week, reached to its maximum at 2 weeks and then decreased gradually from 4 weeks to 6 weeks. Motoneurons died from 4 weeks to 6 weeks. With EGb761 treatment, the number of NOS-positive motoneurons were decreased at each time point and the number of survival motoneurons was increased at each time point compared to control rats.CONCLUSIONS: EGb761 protected the spinal cord motoneurons from avulsion injury. This effect may be related to inhibition of NOS expression.

Objective: To analyze the HIV detection results through different detection routes in Jiading District, Shanghai Municipality from 2009 to 2023, so as to provide the reference for improving HIV detection measures. Methods: Data pertaining to HIV detection in Jiading District from 2009 to 2023 was collected through the HIV/AIDS Comprehensive Control System of Chinese Disease Prevention and Control Information System. The number of HIV detection and HIV positive rates through detection routes including voluntary counseling and testing (VCT) clinics, sexually transmitted disease (STD) clinics, pre-operation and blood transfusion (products), premarital and antenatal periods, other clinical outpatients and other populations were described. Results: A total of 1 729 347 HIV tests were conducted in Jiading District from 2009 to 2023, with an average annual growth rate of 7.55%. A total of 1 125 HIV positive cases were confirmed, with an HIV positive rate of 6.51/104. The number of HIV detection conducted in VCT clinics, STD clinics, pre-operation and blood transfusion (products), premarital and antenatal periods, other clinical outpatients and other populations were 11 516, 112 880, 692 609, 635 770, 196 315 and 80 257, respectively. The main detection routes were pre-operation and blood transfusion (products) as well as premarital and antenatal periods, accounting for 40.05% and 36.76%, respectively.

To detect cadmium ions, we constructed a specific microbial sensor and screened detecting cassettes and different fluorescence proteins. Blue fluorescence protein mTagBFP2 was selected as a reporter and a double-promoters model was used in the construction of the fusion reporter vector Pmer::merR-m-Pmer::mTagBFP2-pMD19-T. The reporter vector was then transformed into Escherichia coli MC4100 wild type strain. The medium, incubation time, initial density for induction, and the optimal detection range were determined. The specificity of the biosensor was also checked. The biosensor responded specifically to cadmium irons with low background, and the linear concentration range detection ranged from 0.1 to 75 μmol/L at the initial OD600 = 0.1 with 2 h incubation in IHMM medium. Thus we successfully constructed a specific biosensor to detect cadmium irons and provided useful strategies for development and optimization of microbial sensors to detect heavy metals.

To explore the general clinical features and treatment outcomes of patients with AIDS-related diffuse large B-cell lymphoma (AIDS-DLBCL) and provide a theoretical basis for diagnosis and treatment, survival prognosis, prevention and management of AIDS-DLBCL patients. AIDS-DLBCL patients who received combined antiretroviral therapy (cART) at Changsha First Hospital from January 2017 to January 2020 were selected in this study. The survival curves were plotted using the Kaplan-Meier method, and the Cox proportional hazards regression model was used to analyze the association between AIDS-DLBCL specific variables and progression-free survival and overall survival. Correlation analysis was conducted based on the clinical features of the patients. A total of 50 AIDS-DLBCL patients were included. Their median age ( Q 1, Q 3) was 52 (44, 59) years, of whom 46 (92%) were male. About 20 (40%) patients received treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), while 23 patients (46%) received treatment with rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP). Survival curve analysis showed that the 2-year progression-free survival rate and overall survival rate of AIDS-DLBCL patients were 56.9% and 61.6%, respectively. Patients with RCHOP protocol combined with EBV-DNA≥1 000 copies/ml had higher progression-free survival rate (χ 2=3.844, P=0.043) and overall survival rate (χ 2=4.662, P=0.031) than those with CHOP protocol combined with EBV-DNA≥1 000 copies/ml. A multivariate analysis showed that male ( HR=2.70, 95% CI:1.10-6.80), EB viral load≥1 000 copies/ml ( HR=1.75, 95% CI:1.12-2.84), HIV-RNA≥200 copies/ml ( HR=4.64, 95% CI: 1.73-12.15), ECOG PS score of 2 to 4 points ( HR=3.54, 95% CI:1.62-7.33), and international prognostic index (IPI) score of 3 to 5 points ( HR=5.21, 95% CI:1.39-20.14) were at a higher risk of disease progression. Patients with EB viral load≥1 000 copies/ml ( HR=0.07, 95% CI:0.05-0.93) on the RCHOP regimen had a small risk of disease progression. Males ( HR=2.87, 95% CI:1.65-9.17), EB viral load≥1 000 copies/ml ( HR=1.61, 95% CI:4.02-9.36), HIV-RNA≥200 copies/ml ( HR=1.19, 95% CI:1.58-2.74), ECOG PS score of 2 to 4 ( HR=6.42, 95% CI:2.55-14.33), IPI score of 3 to 5 points ( HR=2.78, 95% CI:1.41-12.96) had a high risk of mortality. Patients with EB viral load≥1 000 copies/ml ( HR=0.24, 95% CI:0.64-0.90) on the RCHOP regimen had a low risk of mortality. In summary, males, ECOG physical status score of 2 to 4 points, IPI score of 3 to 5 points, EB viral load≥1 000 copies/ml and HIV viral load≥200 copies/ml are risk factors affecting progression-free survival and overall survival of AIDS-DLBCL patients. RCHOP regimen combined with EB viral load≥1 000 copies/ml is a protective factor affecting progression-free survival and overall survival in AIDS-DLBCL patients.

Objective To study the characteristics and follow-up results of 94 people with indeterminate Western blot (WB) results of HIV antibody. Methods A retrospective analysis was conducted on the characteristics and outcome of 94 patients with indeterminate WB results of HIV antibody from AIDS confirmation laboratories in Jiading District from 2016 to 2019. Results The 94 subjects came mainly from clinical diagnostic tests, accounting for 68.09% of the total, followed by counseling tests and maternal examinations, accounting for 12.77% and 10.64%，respectively. Follow-up testing was performed on 48 patients with indeterminate HIV antibodies, with a follow-up detection rate of 51.06%. Among them, 25.00% turned positive during the follow-up, and 39.58% turned negative. There was no significant difference in the follow-up rate between different population groups and WB band-types. The positive conversion rate of counseling test samples was the highest, accounting for 55.56% of all positive conversion cases. There was a total of 14 WB band types, mainly in p24, gpl60 and p24pl60, accounting for 54.26%, 17.02% and 9.57%, respectively. There was a significant difference in the positive conversion rate of antibodies with different patterns of WB bands. The positive conversion rate of WB band type gp160gp41p24 was 100%, while the positive rate of gp160p24, gp160, and p24 was 66.67%, 37.5% and 11.54%, respectively. Conclusion The samples with indeterminate WB results of HIV antibody were mainly from medical institutions, and the follow-up retest rate was low. Follow-up tests of specific populations and samples with specific patterns of WB bands should be strengthened to confirm HIV infection status as soon as possible.

Background In recent years gut microbiota has been found to play an important role in the occurrence and development of various chronic diseases, and diet is an important factor influencing gut microbiota. However, the effects of maternal high-fat diet in pre-pregnancy and pregnancy-and-lactation periods on offspring gut microbiota are still unclear. Objective To investigate the effects of maternal high-fat diet in pre-pregnancy and pregnancy-and-lactation periods on gut microbiota of offspring mice. Methods C57BL/6J female mice were divided into four groups according to the diet patterns (high-fat diet, HFD; control diet, CD) given before and after conception, namely the pre-pregnancy control diet and post-pregnancy control diet group (CD-CD group), the pre-pregnancy control diet and post-pregnancy high-fat diet group (CD-HFD group), the pre-pregnancy high-fat diet and post-pregnancy control diet group (HFD-CD group), and the pre-pregnancy high-fact diet and post-pregnancy high-fat diet group (HFD-HFD group). Female mice were conceived in the same cage with male mice after 6 weeks of feeding, and the successfully conceived females continued to be randomly divided into two groups receiving either high-fat or control diet, and when the offspring mice were born, they were breastfed directly by the mothers, with each mother nursing only one offspring mouse. The number of offspring mice in each group was 6, with half males and half females. The body weight of offspring mice were recorded and body weight gain was compared between the four groups. After the lactational period, fresh feces of the offspring were collected, and the fecal DNA was extracted. Specific primers were designed according to the bacterial 16S rDNA(V3+V4) sequence and then the sequencing was performed using the Illumina HiSeq 2500 platform. Species annotation and operational taxonomic unit (OTU) analysis of sequencing data were conducted using QIMME, USEARCH and R software. In alpha diversity analysis, ACE and Chao1 indices were used to evaluate species richness, Shannon and Simpson indices considered both species richness and evenness. In beta diversity analysis, principal coordinates analysis (PCoA) and analysis of similarities (Anosim analyses) were used to find the differences in composition of gut microbiota between four groups, and line discriminant analysis effect size (LefSe) was conducted to identify which specific taxa contributed to the significant differences between groups. Results A greater effect of post-pregnancy diet on offspring body weight was observed, and the lowest body weight was recorded in the HFD-CD group during the whole experimental period. The results of OTU analysis showed that high-fat diet during post-pregnancy period reduced the number of OTUs in offspring mice, and the results of alpha diversity analysis showed that high-fat diet during post-pregnancy period reduced the richness of intestinal flora (ACE, P<0.05; Chao1, P<0.05), whereas differences in the α-diversity indices did not show statistical significance in the offspring mice with pre-pregnancy high-fat diet. The high-fat diet at different periods also led to changes in the dominant intestinal flora of the offspring. The high-fat diet during post-pregnancy period increased the abundance of Tenericutes (P<0.05), and decreased the abundance of Bacteroides, Epsilonbacteraeota, Cyanobacteria, and Deferribacteres (all Ps<0.05). At the genus level, high-fat diet during both pre-pregnancy and post-pregnancy periods decreased the abundance of Lactobacillus (P<0.05), and high-fat diet during pre-pregnancy period increased the abundance of Alistipes (P<0.05), while high-fat diet during post-pregnancy period increased the abundance of Lachnospira and Ruminococcus, and decreased the abundance of Muribaculaceae and Helicobacter (all Ps<0.05). The results of beta diversity analysis showed that the CD-CD group had a similar flora composition to the HFD-CD group, and the CD-HFD group had a similar flora composition to the HFD-HFD group, and the results of Anosim analysis showed statistically significant differences between groups (R=0.743, P<0.01). The LEfSe analysis counted all species with an effect on the differences between groups greater than the set value, which were Lactobacillus in the CD-CD group, Clostridiales in the CD-HFD group, Bacteroidetes and Helicobacters in the HFD-CD group, and Blautia, Ruminococcaceae, and Roseburia in the HFD-HFD group. Conclusion It is found that varied effects of high-fat diet in different periods on the flora of the offspring mice. The high-fat diet during pre-pregnancy and post-pregnancy periods could reduce the abundance of Lactobacillus, but show different effects on the abundance of other intestinal flora such as Muribaculaceae, Lachnospiraceae, and Helicobacter differed. Diet during post-pregnancy period has a greater influence on modeling the offspring gut microbiota.
