Network Meta-analysis of single Hirudo prescriptions in treatment of ischemic cerebrovascular disease / 中国中药杂志

This study intended to evaluate the efficacy and safety of single Hirudo prescriptions in the treatment of ischemic cerebrovascular disease(ICVD) by frequency network Meta-analysis and traditional Meta-analysis. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library databases were searched to collect the randomized controlled trial(RCT) of single Hirudo prescriptions for ICVD from the inception of the databases to May 2022. The quality of the included literature was evaluated by Cochrane risk of bias tool. Finally, 54 RCTs and 3 single Hirudo prescriptions were included. Statistical analysis was conducted by RevMan 5.3 and Stata SE 15. Network Meta-analysis showed that in terms of the clinical effective rate, the surface under the cumulative ranking curve(SUCRA) of intervention measures was as follows: Huoxue Tongmai Capsules+conventional treatment>Maixuekang Capsules+conventional treatment>Naoxuekang Capsules+conventional treatment>conventional treatment. Traditional Meta-analysis revealed that in terms of the safety of ICVD treatment, Maixuekang Capsules+conventional treatment had higher safety than conventional treatment alone. According to the network Meta-analysis and traditional Meta-analysis, it was found that conventional treatment combined with single Hirudo prescriptions improved the clinical efficacy of ICVD patients, and compared with that of conventional treatment alone, the incidence of adverse reactions of combined treatment was low and the safety was high. However, the methodological quality of the articles included in this study was generally low and there were large differences in the number of articles on the three combined medication. Therefore, the conclusion of this study needed to be confirmed by subsequent RCT.

Changes of intestinal flora in children with acute lymphoblastic leukemia before and after chemotherapy / 中国当代儿科杂志

OBJECTIVES@#To examine the changes of intestinal flora in children newly diagnosed with acute lymphoblastic leukemia (ALL) and the influence of chemotherapy on intestinal flora.@*METHODS@#Fecal samples were collected from 40 children newly diagnosed with ALL before chemotherapy and at 2 weeks, 1 month, and 2 months after chemotherapy. Ten healthy children served as the control group. 16S rDNA sequencing and analysis were performed to compare the differences in intestinal flora between the ALL and control groups and children with ALL before and after chemotherapy.@*RESULTS@#The ALL group had a significant reduction in the abundance of intestinal flora at 1 and 2 months after chemotherapy, with a significant reduction compared with the control group (P<0.05). Compared with the control group, the ALL group had a significant reduction in the diversity of intestinal flora before and after chemotherapy (P<0.05). At the phylum level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Actinobacteria at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05) and a significant increase in the relative abundance of Proteobacteria at 1 and 2 months after chemotherapy (P<0.05). At the genus level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Bifidobacterium at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05); the relative abundance of Klebsiella in the ALL group was significantly higher than that in the control group at 1 and 2 months after chemotherapy and showed a significant increase at 1 month after chemotherapy (P<0.05); the relative abundance of Faecalibacterium in the ALL group was significantly lower than that in the control group before and after chemotherapy and showed a significant reduction at 2 weeks and 1 month after chemotherapy (P<0.05). The relative abundance of Enterococcus increased significantly at 1 and 2 months after chemotherapy in the ALL group (P<0.05), and was significantly higher than that in the control group (P<0.05).@*CONCLUSIONS@#The diversity of intestinal flora in children with ALL is significantly lower than that in healthy children. Chemotherapy significantly reduces the abundance of intestinal flora and can reduce the abundance of some probiotic bacteria (Bifidobacterium and Faecalibacterium) and increase the abundance of pathogenic bacteria (Klebsiella and Enterococcus) in children with ALL.

Objective More and more research shows microangiopathy may occur in the early stage of diabetes. The purpose of this study was to observe the relationship between OGTT 1-hour hyperglycemia (1hPG) and 2-hour hyperglycemia (2hPG) levels and urinary albumin creatinine ratio (UACR).Methods We retrospectively analyzed 408 patients with primary hypertension of grade 2 or above who were eligible for 2015 World Health Organization (WHO) outpatient and inpatient visits from September 2015 to April 2018 in our hospital for a course of up to 10 years. All selected participants underwent an OGTT test (1 and 2 hour post-sugar glucose) and records were made on fasting plasma glucose (FPG), OGTT1-hour blood glucose (1 hPG), OGTT 2-hour blood glucose (2 hPG). All the patients were divided into 4 groups according to blood glucose levels: NGT group (n=100), 1 h PG group(n=102), 2h PG group(n=104), 1h PG/2h PG group (n=102). Records were made on the clinical data of 408 patients, including height, weight, BMI, gender, age, history of hypertension, smoking history, blood pressure, blood lipids, creatinine and other general clinical data, and the calculation of glomerular filtration rate (eGFR) values was based on creatinine values and age values to analyze the relationship between 1 hHPG and 2 hHPG levels with ACR.Results No significant difference was found among the four groups in the aspects of hypertension course, age, gender, body mass index (BMI), diastolic blood pressure, lipid metabolism index and fasting blood glucose(P>0.05). There were significant difference in systolic blood pressure, serumcreatinine, eGFR, and ACR among different levels of increased blood glucose(P<0.05). ACR in 1h PG group, 2h PG group and 1h PG/2h PG group were significantly higher than NGT group(P<0.01), ACR in 1h HPG/2hHPG was significantly higher than 1h PG group(P<0.05) and ACR in 1h PG group was significantly higher than 2h HPG group(P<0.05). The logistic regression analysis showed that 1h PG(OR=2.461, 95%CI:1.947-3.112), creatinine (OR=1.071, 95%CI:1.027-1.117) and 2h PG(OR=2.016, 95%CI:1.500-2.710) were risk factors for microalbuminuria(P<0.01).Conclusion The abnormalities of 1h PG and 2h PG are associated with ACR, which may become the key index for predicting early kidney damage.

Pathological changes of livers were observed by hematoxylin-eosin staining of paraffin section.</p><p><b>RESULTS</b>Compared with the model group, the serum levels of TC, TG, FFA, FBG, FINS, IRI, ISI, and the liver levels of TC and TG in CHSG-H, CHSG-M, CHSG-L groups showed significant declines (P<0.01 or P<0.05); the serum levels of HDL-C, HOMA-IS were significantly increased (P<0.01 or P<0.05); the expression of leptin mRNA was dramatically decreased and the expression of adiponectin mRNA was increased in the hepatic tissue (P<0.01 or P<0.05). The fatty deposition of liver cells could also be alleviated.</p><p><b>CONCLUSION</b>CHSGS could up-regulate the expression of adiponectin mRNA and down-regulate the expression of leptin mRNA on the liver, suggesting the CHSGS had positive therapeutic effect on NAFLD in rats with IR.</p>

Tuberous sclerosis and Langerhans cell histiocytosis combined with secondary hemophagocytic lymphohistocytosis in infancy: a case report / 临床儿科杂志

Objective To explore the diagnosis of tuberous sclerosis (TSC) combined with Langerhans cell histiocytosis (LCH) and secondary hemophagocytic lymphohistocytosis (HLH).Methods One case diagnosed of TSC combined wiht LCH and secondary with HLH in infancy was retrospectively analyzed.Results One year and 4-month-old Uyghur boy when he was 4-month-old,there was onset of infantile spasm.Gene detection was performed when he was one year old and showed the absence of the exon 3 to 10 ofTSC2 gene.The diagnosis of TSC was confirmed.Meanwhile,the boy also suffered with skin rash all around,fever,hepatosplenomegaly,and bone defect.The diagnosis of LCH was confirmed by skin biopsy.In addition,the boy was complicated HLH.Conclusions It is rarely seen that TSC combined with LCH,and secondary HLH in one case.The clinical features were complex and need to be differetiate.

Protective effects of miR-34a on brain function of mice with sepsis by regulating Notch-1/NF-κB signaling pathway / 中华急诊医学杂志

Objective To observe the dynamic changes of TNF-α,IL-1β,IL-6,IL-10,and expressions of Notch-1,NF-κB mRNA and their protein levels in the brain tissue of septic mice and intervention effects of intrathecal injection of lentiviral vector of miR-34a gene for regulating Notch-1/NF-κB signaling pathway.Methods A total of 54 mice of clean grade were divided randomly (random number) into four groups,namely sham group (n =9),in which sham-operated laparotomy was performed;CLP group (n=15),in which the cecum ligation operation (CLP) was performed;NC group (n =15),in which intrathecal injection of lentivirus 5 μL (concentration 5 × 108 TU/mL),one time per day,for 3 days,then CLP was performed on the seventh day;intervention group (n =15),in wihch intrathecal injection of miR-34a lentivirus 5 μL (concentration 5 × 108 TU/mL),one time per day,for 3 days,then CLP was performed on the seventh day.The mice of four groups were sacrificed 24 h after modeling or operation.The changes of behavior of mice was observed and the neurological scores were assessed 24 h after CLP.The levels of TNF-α,IL-1β,IL-6 and IL-10 in the brain were measured by ELISA method.The mRNA expression and protein levels of Notch-1 and NF-κB in the brain tissue were measured by real-time PCR and Western blot method,respectively.Pathological changes of brain tissue were observed under light microscope.Results The neurological scores,the cerebral TNF-α,IL-6 levels,the mRNA expression and protein level of NF-κB (P＜0.01),and IL-1β levels (P ＜0.05) in CLP group 24 h after modeling were higher than those in sham group.The cerebral IL-10 level and the mRNA expression and protein level of Notch-1 (P ＜ 0.01) in CLP group 24 h after modeling were lower than those in sham group.The neurological scores,the cerebral TNF-α and IL-1β levels,and the protein level of NF-κB (P ＜0.01),and IL-6 (P ＜ 0.05) in NC group 24 h after modeling were higher than those in sham group.The cerebral IL-10 level,the mRNA expression and protein level of Notch1 in NC group 24 h after modeling were lower than those in sham group.There were no significant difference in neurological socres,IL-1β and IL-6 levels between intervention group and CLP group (P ＞ 0.05).The IL-10 level (P ＜ 0.05) and the mRNA expression (P ＜ 0.05) and protein level (P ＜ 0.01) of Notch-1 in intervention group 24 h after modeling were lower than those in CLP group.There were no significant difference in biomarkers between NC group and CLP group (P ＞ 0.05).The degree of cerebral damage found under light microscope was also ameliorated in intervention group compared with CLP group 24 h after modeling.Conclusions The effects of miR-34a via regulating Notch-1/NF-κB signaling pathway on brain function exerts cerebral protective effects in septic mice.

Application of He-Ne laser combined with TDP irradiation in the treatment of herpes zoster ophthalmicus / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the effect of He-Ne laser combined with TDP irradiation in the treatment of herpes zoster ophthalmicus.METHODS: Totally 22 patients (22 eyes) with herpes zoster ophthalmicus were treated by He-Ne laser irradiation combined with TDP (Group A).Another 22 patients (22 eyes) with herpes zoster ophthalmicus (Group B) were treated by medication.The duration of the disease, the incidence of complications, and the time of pain relief were compared between the two groups.RESULTS: The cure rate of Group A was 91%, that of Group B was 73%, there was no significant difference between the two groups (x2=1.375, P>0.05).The average cure time of Group A was 8±2.22d, Group B was 12±1.88d, the difference between the two groups was statistically significant (t=5.22, P<0.05).The complication rate of Group A was 18%, Group B was 59%, the difference between the two groups was statistically significant (x2=6.86, P<0.05).The average pain relief time of Group A was 5±1.23d, Group B was 10±1.34d, the difference between the two groups was statistically significant (t=11.17, P<0.05).CONCLUSION: He-Ne laser combined with TDP irradiation can shorten the treatment time of herpes zoster ophthalmicus, shorten the course of disease, reduce the incidence of complications, relieve pain, with no significant effect on the cure rate of herpes zoster ophthalmicus.
