Systematic review and Meta-analysis of efficacy and safety of Kushen Gelatum combined with antibiotics in treatment of bacterial vaginosis / 中国中药杂志

This study aims to systematically evaluate the clinical efficacy and safety of Kushen Gelatum combined with antibiotics for treating bacterial vaginosis. The randomized controlled trial(RCT) of Kushen Gelatum for treating bacterial vaginosis were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, and Cochrane Library with the time interval from inception to January 2023. Data were extracted from the included RCT by 2 investigators, including the sample size, characteristics of patients, interventions and controls, outcome indicators, and adverse effects. The Cochrane collaboration network's bias risk assessment tool was used for methodolo-gical quality evaluation of the included trials. RevMan 5.4 was employed to perform the Meta-analysis. A total of 19 RCTs were inclu-ded, involving 1 980 patients with bacterial vaginosis. Meta-analysis showed that, compared with nitroimidazoles alone, Kushen Gelatum + nitroimidazoles improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.24, 95%CI[1.13, 1.36], P<0.000 01), laboratory tests(RR=1.16, 95%CI[1.06, 1.26], P=0.000 9), and clinical symptoms(RR=1.26, 95%CI[1.08, 1.46], P=0.003), and reduced the leukocyte esterase positive rate(RR=0.29, 95%CI[0.17, 0.48], P<0.000 01) and the recurrence rate(RR=0.37, 95%CI[0.23, 0.58], P<0.000 1). Compared with lincomycin antibiotics(clindamycin) alone, Kushen Gelatum + lincomycin antibiotics(clindamycin) improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.06, 1.31], P=0.003) and laboratory tests(RR=1.27, 95%CI[1.04, 1.54], P=0.02), reduced the recurrence rate(RR=0.20, 95%CI[0.05, 0.75], P=0.02), and shortened the time to relief of burning sensation(MD=-1.70, 95%CI[-2.15,-1.26], P<0.000 01), vaginal itching(MD=-0.82, 95%CI[-1.30,-0.34], P=0.000 8), and abnormal leucorrhea(MD=-1.52, 95%CI[-1.98,-1.06], P<0.000 01). Compared with nitroimidazoles + probiotics, Kushen Gelatum + nitroimidazoles + probiotics improved the total response rate in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.02, 1.36], P=0.03) and reduced the recurrence rate(RR=0.27, 95%CI[0.09, 0.76], P=0.01). Kushen Gelatum combined with antibiotics demonstrates a potential therapeutic effect on bacterial vaginosis, whereas the number and quality of the relevant clinical studies remain to be improved. The process of clinical trial should be standardized to improve the quality of evidence, so as to provide strong evidence to guide the application of Kushen Gelatum in clinical practice.

Different Compatibility Ratio and Clinical Application of Shenfutang / 中国实验方剂学杂志

Shenfutang is a famous prescription used in clinic. It has been used for more than one thousand years, and currently is still widely used in clinic, with a significant effect. Shenfutang was first recorded in the Shengji Collection. It consists of two herbs, namely Ginseng Radix Et Rhizoma and Aconiti Lateralis Radix Praeparata. It can be used to mainly treat syncope and collapse due to sudden collapse of Yang Qi, and the symptoms include disfigurement of the extremities, cold sweats, cold limbs, umbilical and abdominal pain, weak breathing, and slight desire. Ginseng supports healthy Qi, and comforts five organs. Aconitum is good at activating twelve meridians and collaterals. With the effect of returning the yang to rescue the enemy, aconitum can also support yang. Different ratios of ginseng and aconitum are combined for reinforcing Yang of heart, kidney and spleen, so as to treat various syndromes. However, the occurrence and development of diseases are complicated and changeable. Different ratios of Shenfutang may increase the efficacy due to the synergistic effect, or weaken or even lose the original efficacy due to mutual antagonism. Different ratios of ginseng and aconitum can be used for different diseases, such as cardiovascular disease, various types of inflammation, respiratory diseases. In the existing literatures on Shenfutang, there is a lack of systematic summarization for how to adjust the ratios. This paper introduces the effect and mechanism of the combination, and summarizes different ratios of the two herbal ingredients, so as to provide certain reference for the clinical application.

Effect of Cesarean Section on the Severity of Postpartum Hemorrhage in Chinese Women: The Shanxi Study / 华中科技大学学报（医学）（英德文版）

Postpartum hemorrhage (PPH) is one of the most adverse obstetric outcomes.Our aim is to detect the risks of multilevel PPH in different cesarean section (CS) groups [including nulliparous CS with indications,nulliparous CS without indications,repeat cesarean (RC),vaginal birth after cesarean (VBAC),cesarean after vaginal birth (CAVB)].We conducted a retrospective cohort study,and the data on 127 145 women collected from January 2014 to May 2016 and from 35 tertiary hospitals in Shanxi province,China,were reviewed.Based on the measuring results of PPH,an ordered logistic regression model was used to analyze the adjusted PPH risks for each of the CS groups,and comparisons were drawn between them.Finally,a total of 99 066 nulliparous (77.92％) and 28 079 multiparous (22.08％) women were observed.The number of CS cases was 61 117,and the rate for CS was 48.07％.A total of 10 029 women did not show indications for CS and accounted for 16.41％ of the CS parturient,whereas 9103 women underwent a repeated cesarean,with a CS frequency of 14.89％.The number of VBAC cases was 989,whose rate was 9.88％ in prior CS women.The number (proportions) of PPH was 3658 (2.88％) in LI (PPH volume:≥900 and ＜1500 mL),520 (0.41％) in L2 (PPH volume:≥1500 and＜2100 mL),and 201 (0.16％) in L3 (PPH volume:≥2100 mL).The Ln (n=1,2,3,etc.) represented the increasing order of PPH severity.In the adjusted results,compared with spontaneous vaginal delivery (SVD) as the reference group,in the adjusted result for nulliparous,there was a decreased PPH risk in CS with indications (OR:2.32;CI:2.04-2.62),which was lower than that of CS without indications (OR:2.50;CI:2.01-2.96).The highest PPH risk in all subgroups (i.e.nulliparous and multiparous groups) was observed in the RC (OR:3.61;CI:3.16-4.17),which was nearly twice higher than that of the VBAC (OR:1.82;CI:1.33-2.52).CAVB (OR:1.03;CI:0.65-1.62) showed no significant difference with the reference group.Thus,we deemed that CS should be avoided in nulliparous pregnancies unless indicated,to prevent or reduce the rates for the use of RC or VBAC which are high risks of severe PPH to the parturient women.

Assessment of schistosomiasis transmission risk after flood damage in Wuhan City / 中国血吸虫病防治杂志

To assess the schistosomiasis transmission risk after flood damage in Wuhan City.Schistosomiasis epidemic villages in Wuhan City were selected by using probability proportional to size sampling (PPS). The field investigations of Oncomelania hupensis snails, the activity of people and cattle on marshland, water infectivity of schistosome, reservoir host infection and wild feces contamination were conducted. I–III levels of risk environments were assessed and treated with appropriate measures.A total of 90 schistosomiasis epidemic villages and 170 environments were monitored. Totally 9 811 snails were dissected but no Schistosoma japonicum infected snails were found. There were significant decreases in the density of snails and the survival rate of living snails after the flood (χ2 = 102.517, t = 4.724, both P < 0.01). Totally 289 pieces of wild feces were captured, and no eggs of S. japonicum were detected. A total of 11 surveillance and forecast sites were detected on water systems, and 221 sentinel mice were placed. After breeding, 219 sentinel mice survived (99.10%), and no schistosome infection was detected. In addition, 1 720 mouse traps were placed in 3 survey sites, and 66 Apodemus agrarius were captured, and no schistosome-infected ones were found. All of the environments were assessed as Grade III. Meanwhile, 5 key schistosomiasis control areas were determined, and no emergency happened after the implementation of comprehensive control interventions.The risk of schistosomiasis transmission remains low in Wuhan City after the flood, but the potential epidemic risk cannot be ignored.

<p><b>OBJECTIVE</b>To evaluate the effect of long-term therapy with entecavir and Fufang Biejia Ruangan tablet in patients with chronic hepatitis B (CHB)-associated fibrosis and explore the synergistic therapy that accelerates the reversion of liver fibrosis.</p><p><b>METHODS</b>A total of 197 patients with CHB-associated fibrosis were recruited from Nanfang Hospital between June, 2010 and June, 2015. The patients were divided into two groups after matching for age, gender and liver stiffness measurement (LSM), namely group A (n=98) treated with Fufang Biejia Ruangan Tablet plus entecavir, and group B (n=99) to receive entecavir only. HBV DNA quantification, HBV serological indicators, blood biochemical indexes, and results of abdominal ultrasound and FibroScan were recorded every 12 weeks. FibroScan values were converted to Metavir staging.</p><p><b>RESULTS</b>Both groups showed significant decreases in serum levels of HBV DNA, alanine aminotransferase (ALT), and LSM value from baseline (all P<0.05). The median time to achieve Metavir fibrosis staging improvement were 72 weeks in group A and 96 weeks in group B (P<0.05), and the median time to achieve ALT and AST normalization were 12 and 24 weeks in Group A, respectively, significantly shorter than the time in group B (P<0.05). No significant difference was found between the two groups in HBV DNA undetectable rate and HBeAg seroconversion rate.</p><p><b>CONCLUSION</b>The combination therapy with Fufang Biejia Ruangan tablet and entecavir produces a stronger efficacy than entecavir alone in the treatment of chronic hepatitis B patients with liver fibrosis, and Fufang Biejia Ruangan tablet shows an obvious hepatoprotective effect in these patients.</p>

Preliminary observation on hepatic arterial infusion under temporary hepatic circulation occlusion in rabbits / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To explore the advantages, feasibility and limitations of hepatic arterial infusion under temporary hepatic circulation occlusion.</p><p><b>METHODS</b>Twelve rabbits were randomly divided into two groups: hepatic artery infusion group (HAI group) and hepatic artery infusion under temporary hepatic circulation occlusion group (HAI-THCO). Microcatheters were separately inserted into the proper hepatic artery and right hepatic vein. For the HAI group, 5-Fu (10 mg/ml and 100 mg/kg) was infused into the common hepatic artery with a high pressure injector for 10 minutes. For the HAI-THCO group, the common hepatic artery and hepatic portal vein were temporarily occluded for 15 minutes using artery clamp when 5-Fu was being infused. For the two groups, at 2, 5, 10, 15, 20 and 30 min after the start of infusion, blood samples of the hepatic flow were collected from the right hepatic vein and of the systemic blood flow from the inferior vena cava, 1 ml at each time point. The blood drug concentration of these blood samples was determined by high performance liquid chromatography (HPLC).</p><p><b>RESULTS</b>Except that at 20 and 30 min after infusion, in the HAI group, the blood drug concentration of hepatic circulation was significantly higher than that of systemic circulation (P < 0.05). But in the HAI-THCO group, the blood drug concentration of hepatic circulation was significantly higher than that of systemic circulation at all the time points (P < 0.05). The hepatic circulation blood drug level of the HAI-THCO group was always significantly higher than that of the HAI group (P < 0.05), but the systemic circulation blood drug concentration of the HAI-THCO group was always lower (P < 0.05). The hepatic circulation maximum concentration (Cmax) of blood drug concentration of the HAI-THCO and HAI groups was (23.057±3.270) µg/ml and (4.408±1.092) µg/ml, respectively, and the Cmax of HAI-THCO group was significantly higher (P < 0.001), being 5.23 times of that of HAI group. The systemic circulation Cmax of the two groups was (1.456±0.217) µg/ml and (2.335±0.669) µg/ml, respectively, and the Cmax of HAI group was 1.60 times higher than that of the HAI-THCO group (P = 0.022). The hepatic circulation AUC of HAI-THCO and HAI groups was (368.927±52.416) µg·min·ml(-1) and (65.630±14.928) µg·min·ml(-1), respectively. The AUC of HAI-THCO group was 5.62 times higher than that of the HAI group (P < 0.001). The systemic circulation AUC of the two groups was (27.193±3.948) µg·min·ml(-1) and (45.301±12.275) µg·min·ml(-1), respectively. The AUC of HAI group was 1.67 times higher than that of the HAI-THCO group (P = 0.014).</p><p><b>CONCLUSIONS</b>HAI-THCO is a simple and effective regional hepatic infusion chemotherapy technique. It can be performed through occluding the common hepatic artery and the hepatic portal vein by balloon catheter. HAI-THCO can not only increase the blood drug concentration in the hepatic circulation, but also decrease the blood drug concentration in the systemic circulation, therefore, distinctly lowering the systemic toxicity.</p>

The concentration-time curve fitted two-compartment open model which was linear kinetics elimination after a single intravenous injection of TAT-haFGF(14-154) in rat at the dose of 300 microg x kg(-1). The half life time was 0.049 +/- 0.03 h for distribution phase and 0.55 +/- 0.05 h for elimination phase, and the weight was 1/C2. The result showed that TAT-haFGF(14-154) could be detected in the brain by ELISA and immunohistochemistry, the elimination of TAT-haFGF(14-154) in rat was swift, and TAT-haFGF(14-154) could penetrate across the blood-brain barrier, distribute in pallium and hippocampus and locate in the nucleus.

Genetic recombinant prokaryotic expression of augmenter of liver regeneration and preparation of polyclonal antibodies in rats / 中国组织工程研究

BACKGROUND:An abroad study repoRed the distribution and expression of augmenter of liver regeneration(ALR)in the central nervous system.There are few literatures on how to prepare and evaluate ALR protein polyclonal antibody in recombinant rats,and how to construct prokaryotic expression vector.There are no repots concerning ALR in the central nervous system in China.OBJECTIVE:TO express ALR fusion protein in E coli BL21 and prepare and identify polyclonal antibody.METHODS:RNA was extracted from the hippocampus of Sprague Dawley rats.The prokaryotic expression plasmid pET28a-ALR was constructed and the positive recombinant plasmid was transformed into BL21.Protein ALR was expressed by inducing transformed BL21 with Isopropyl-β-D-thiogalactopyranoside(IPTG)and purified by Ni~(2+)affinity chromatography column after immune the rabbit for 4 times.the serum of rabbits was extracted from hear as polyclonal antibody.The titer and specificity of the rabbit's antiserum was respectively measured by ELISA and Western blotting The following parameters were measured:construction of prokaryotic expression plasmid pET26a-ALR;pET28a-ALR recombinant enzyme digestion evaluation;results of ELISA and Western-blotting.RESULTS AND CONCLUSION:Expecting bands were obtained by double enzyme digestion electrophoresis,respectively 5.3 kb and 0.4 kb.Nucleotide sequence analysis verified that prokaryotic expression vector pET28a-ALR was successfully constructed.The 19 ku fusion protein was successfuIly expressed.The titer of the antiserum measured by ELlSA could achieve 1:2 000 This indicated that antibody and purified recombinant ALR had a good reaction.and high titer.could meet the experimental require.Western blotting analysis proved that the antibody could identify the prokaryotic expression product of ALR.Prokaryotic expression system expressed ALR fusion protein,prepared and purified polyclonal antibody of ALR protein,and could meet the experimental require of ALR immunoblotting.

Analysis of oral and maxillofacial malignant tumors implanted with 125I radioactive seeds under guidance of ultrasound / 中华医学超声杂志（电子版）

Objective To retrospectively analyze 45 cases of oral and maxillofacial malignant tumors and to assess the efficacy and feasibility of oral and maxillofacial malignant tumors implanted with 125I radioactive seeds under guidance of ultrasound.Methods A total of 47 focuses in these 45 patients were determined with the size of these tumors by imaging study,the section was planed by ultrasound,the number and distribution of radioactive seeds were determined with the help of the particle treatment planning system,and were percutaneously implanted particles under guidance of ultrasound.The number and the distribution of particles were assessed by CT.Efficacy endpoints were reexamined and evaluated regularly by ultrasonic and CT according to the standards of WHO.Results The total percentage of efficacy was 70.2% (including complete remission,partial remission).The treatment effect of metastatic carcinoma of lymph node is superior to the parotid tumor.There was no serious complication during the period of implanting and 2 patients with oral ulcers were found after operation.Conclusion The oral and maxillofacial malignant tumor treated implanted with 125I radioactive seeds under guidance of ultrasound is very effective and safe,which is deserved to popularize.The ultrasound is the first choice as a guided method for oral and maxillofacial malignant tumors.
