Objective To investigate the effects of modified Simiao San combined with Metronidazole Tablets on immune factors,inflammatory factors,and oxidative stress in patients with bacterial vaginosis(BV).Methods Eighty BV patients treated at Dongguan Hospital of Guangzhou University of Chinese Medicine(Dongguan Traditional Chinese Medicine Hospital)from March 2023 to April 2024 were equally randomly divided into a control group(40 cases,treated with Metronidazole Tablets)and a study group(40 cases,treated with modified Simiao San plus Metronidazole Tablets).The treatment for the two groups lasted for 7 days.Serum immunologic factors[immunoglobulin(Ig)A,IgG,and IgM],inflammatory factors[C-reactive protein(CRP),tumor necrosis factor α(TNF-α),and interleukin-6(IL-6)],and oxidative stress markers[superoxide dismutase(SOD),malondialdehyde(MDA),and glutathione peroxidase(GSH-Px)]in the two groups were measured before and after treatment.After treatment,symptom resolution time,clinical efficacy,and the incidence of total adverse reactions were compared between the two groups.Results(1)After 7 days,the total effective rate was 95.00%(38/40)in the study group versus 77.50%(31/40)in the control group(tested by chi-square test,P＜0.05).(2)The study group showed significantly shorter time to the resolution of profuse or scanty leukorrhea,odor of leukorrhea,vulvar itching,vaginal pain,and vaginal mucosal hyperemia(all P＜0.01)than the control group.(3)After treatment,both groups exhibited increased IgA,IgG,and IgM(P＜0.05)compared to those before treatment,with greater improvements in the study group(P＜0.01).(4)After treatment,serum levels of inflammatory factors of CRP,TNF-α,and IL-6 in both groups decreased(P＜0.05),with superior reductions in the study group(P＜0.01).(5)After treatment,serum levels of oxidative stress markers of SOD and GSH-Px levels rose(P＜0.05),while MDA declined(P＜0.05)in both groups,and the study group demonstrated more pronounced improvements(P＜0.01).(6)Adverse reaction rates were 5.00%(2/40)and 15.00%(6/40)in the study group and control group,respectively,the differentce being no statistical significance between the two groups(P＞0.05).Conclusion Modified Simiao San combined with Metronidazole Tablets significantly alleviates BV symptoms,improves immune function,and inhibits inflammatory response and oxidative stress,demonstrating satisfactory efficacy and high safety.

Objective To explore the medication rules and therapeutic principles of Zhang Jingyue's miscarriage prevention therapies based on data mining technique and literature analysis.Methods The prescription data recorded in the chapter about pregnancy and fetal development from the volume of Women's Diseases in Jing Yue Quan Shu(Jingyue's Complete Works)were collected to establish a database.Frequency analysis,association analysis,and cluster analysis of the herbal medicines from the prescriptions for preventing miscarriage were performed using SPSS Modeler 18.0 and SPSS Statistics 26.0 to investigate Zhang's medication rules.Additionally,discussions on miscarriage prevention in the chapter about pregnancy and fetal development were systematically reviewed to summarize his therapeutic principles.Results A total of 76 miscarriage-prevention prescriptions involving 102 herbal medicinals were analyzed.Among them,26 high-frequency herbal medicinals(used≥5 times)were identified,and primarily belonged to the tonifying deficiency category(11 medicinals).Association analysis revealed 10 association rules with high support,such as"Atractylodis Macrocephalae Rhizoma→Ginseng Radix et Rhizoma"and"Glycyrrhizae Radix et Rhizoma Praeparata cum Melle→Ginseng Radix et Rhizoma,Atractylodis Macrocephalae Rhizoma".The network graph of drug association presented high-correlation herbs including Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Atractylodis Macrocephalae Rhizoma,Poria,Ginseng Radix et Rhizoma,and Angelicae Sinensis Radix.Cluster analysis yielded four core prescription groups:(1)Ziziphi Spinosae Semen,Polygalae Radix,Dioscoreae Rhizoma,and Corni Fructus;(2)Paeoniae Radix Alba,Chuanxiong Rhizoma,Rehmanniae Radix Praeparata,Atractylodis Macrocephalae Rhizoma,Ginseng Radix et Rhizoma,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Angelicae Sinensis Radix,Poria,and Citri Reticulatae Pericarpium;(3)Rehmanniae Radix,Glycyrrhizae Radix et Rhizoma,and Scutellariae Radix;(4)Pinelliae Rhizoma,Magnoliae Officinalis Cortex,Zingiberis Rhizoma Recens,and Jujubae Fructus.Zhang's therapeutic principles for preventing miscarriage were as follows:(1)treating primary diseases together by preventing miscarriage;(2)monthly-specific cultivation of the fetus to preemptively address deficiencies;(3)emphasis on maternal health to consolidate fetal vitality;(4)strict adherence to medication and dietary contraindications and lifestyle management during pregnancy.Conclusion Zhang Jingyue's miscarriage-prevention principles emphasize etiological diagnosis with dual focus on treating primary diseases and preventing miscarriage.His therapies prioritize replenishing qi and blood,skillfully regulating spleen-stomach function and qi movement by employing special and mild herbs and prescribing simplified and flexible formulas.These medication rules and therapeutic principles may provide valuable references for modern miscarriage-prevention strategies.

Objective To investigate the clinical and biologic characteristics of acute myeloid leukemia (AML) with 6q deletions (6q-). Methods Two cases of with 6q deletions (6q-) were here described, and all the AML cases with 6q- found in the literature were reviewed. Results Two cases were diagnosed with AMLMt and AML-M2, respectively. Myloloid markers were positive on the leukemia cells in both cases, none of them expressing lymphocytic antigens. The karyotype of these patients were 46,XX,del(6)(q21q25),t(4; 7)(q10;q10)[3]/46,XX,del(6)(q21q25)[2]/46,XX[25], and 46,XX,del(6)(q23),t(7;11)(p15;p15)[5]/46,XX,t(7;11)' (p15;p15)[9]/46,XX [6]. Until now, 28 cases (including present 2 cases) of AML with 6q- have been documented in the world literature. Many of the AML patients with 6q -have additional chromosomal abnormalities. The breakpoints on 6q- were widely distributed from q12 to q27, mainly involved in the 6q21-23 region. Overall, the AML patients with 6q- were associated with an unfavorable clinical outcome, with a poor response to chemotherapy and a shorter duration. 6q-clone may itself confer a malignant clinical outcome. The 6q- found in some AML cases may associate with leukemogenesis via an activation of an oncogene other than myb or deletion of an antioncogene located in the long arm of chromosome 6. Conclusion Deletion of 6q is a very rare event in AML. AML with 6q- had distinct biologic features and a. poor clinical outcome.

Objective To isolate and study the phenotype and biological characteristics of chronic myelogenous leukemia-derived mesenchymal stem cells. Methods Cultivate the mesenchymal stem cells from chronic myelogenous leukemia in vitro, identify the immunophenotype by fluorescence-activated cell sorter (FACS), and detect the bcr-abl fusion gene by RT-PCR and FISH. Results The mesenchymal stem cells from chronic myelogenous leukemia can express the bcr-abl fusion gene. Conclusion These findings provide the evidence that the rearrangement of bcr-abl gene might happen at least more primitive than CD+34 CD-38 cells.

BACKGROUND: Studies indicated that lipid peroxidation due to increase of free radical is the key factor of ischemia/reperfusion injury.Shinyleaf pricklyash root extracts, rutaceae plant, is bitter in taste, no stimulation, which has the effects of promoting qi, relieving pain, promoting blood circulation by removing blood stasis, dispelling wind and dredging collaterals and antioxidation.OBJECTIVE: To observe the influence of nitidine chloride on myocardial ischemia/reperfusion injury in rats and analyze its mechanism.DESIGN: Randomized controlled study.SETTING: Departmentof Pharmacology and Department of Chemistry,Guangxi Medical University.MATERIALS: A total of 60 healthy Wistar rats were selected, half male and half female, with the body mass of 250-300 g. Nitidine chloride was provided by Department of Chemistry, Guangxi Medical University, batch number 20050609. MS4000U biological signal quantitative record analysis system, 722N evident spectrophotometer, hydrochloric acid verapamil (batch number 020701, 2 mL in each), malondialdehyde (MDA) and superoxide dismutase (SOD) kit were purchased from Guangzhou Longfeida Technology Co., Ltd., Shanghai Precision Scientific Instruments Corporation, Shanghai Harvest Pharmaceutical Co, Ltd. and Nanjing Jiancheng Bioengineering Institute, respectively. Hitachi 7170A full automatic biochemistry analyzer was also applied.METHODS: The experiment was performed at the Department of Pharmacology and Department of Chemistry, Guangxi Medical University between June 2004 and May 2006. ①Totally 60 healthy Wistar rats with normal ECG (half male and half female) were randomly divided into 6 groups:sham operation group, model group, 2, 1, 0.5 mg/kg nitidine chloride groups, positive control group with 10 rats in each group. The rats in the sham operation group received threading without deligation, and 90 minutes later the experiment was accomplished. Other 50 rats received left anterior descending branch of coronary artery deligation, ischemia for 30 minutes reperfusion for 60 minutes. 2 mg/kg verapamil, 2,1,0.5 mg/kg, 5 mL/kgnitidine chloride, saline of the same volume were injected into femoral vein in rats of the positive control group, different doses nitidine chloride groups and model group, respectively 10 minutes before deligating left anterior descending branch of coronary artery. ②Monitoring was conducted successively with standard limb Ⅱ lead ECG when performing reperfusion. Type,incidence rate and duration of cardiac arrhythmia were recorded within 60minutes. Change of ST segment was also recorded after reperfusion for 15minutes and 60 minutes. ③At the end of experiment, serum myocardial enzymology indexes were measured wi th full automatic biochemistry analyzer.MDA content and SOD activity in myocardial tissues were examined with thiobarbituric acid(TBA) method and xanthine oxidase (XOD) method, respectively. ④Measurement data and enumeration data between two groups were compared with t test and x2 test. MAIN OUTCOME MEASURES: Occurrence of cardiac arrhythmia, ECG ST segment elevation, change of serum myocardial enzymology indexes, MDA content and SOD activity of myocardial tissues in rats of each group.RESULTS: A total of 60 rats were involved in the result analysis. ①Degree of cardiac arrhythmia and ECG ST segment elevation of rats: The emergency time of cardiac arrhythmia in 1 and 2 mg/kg nitidine chloride groups was significantly later than that in the model group (P ＜ 0.05,0.01). The duration of cardiac arrhythmia in the 1 and 2 mg/kg nitidine chloride groups and positive control group was obviously shorter than that in the model group (P ＜ 0.05-0.01). The incidence rates of various kinds of cardiac arrhythmia were markedly less than those in the model group (P ＜ 0.01). The degree of ST segment elevation at reperfusion for 15 and 60 minutes was remarkably lower than that in the model group (P ＜ 0.05-0.01). ②Serum myocardial enzyme level: It was significantly higher in the model than the sham operation group after 60-minute myocardial ischemia and reperfusion (P?.01). Activity of myocardial enzyme in the 1 and 2 mg/kg nitidine chloride groups was remarkably lower than that in the model group (P ＜ 0.01,P ＜ 0.05). The level of myocardial enzyme decreased with the increase of nitidine chloride. It was lower significantly in the positive control group than the model group (P ＜ 0.05-0.01 ). ③SOD activity of myocardial tissues: It was markedly lower in the model group than the sham operation group after 60-minute myocardialischemia and reperfusion (P ＜ 0.01); It was dramatically higher than in the 1 and 2 mg/kg nitidine chloride groups than the model group (P ＜ 0.01). The activity also increased with the increase of nitidine chloride. ④MDA content of myocardial tissues: It was distinctly higher in the model group than the sham operation group after myocardial ischemia reperftsion for 60 minutes (P ＜ 0.01). It was remarkably lower in the 1 and 2 mg/kg nitidine chloride groups than the model group (P ＜ 0.01). The content decreased with the increase of nitidine chloride. It was obviously lower in the positive control group than the model group (P ＜ 0.05 ).CONCLUSION: ①1 and 2 mg/kg nitidine chloride can reduce the incidence rate of cardiac arrhythmia in rats with myocardial ischemia and reperfusion, postpone the emergence time of cardiac arrhythmia and shorten its duration, decrease the degree of ST segment elevation after reperfusion for 15 minutes and 60 minutes, which have similar effect with verapamil.② 1 and 2 mg/kg nitidine chloride can reduce the release of myocardial enzyme, relieve the severity of oxygen-derived free radicals injury, and has the effect of protecting myocardial injury during ischemia-reperfusion, in which represents a dose-dependent effect.

BACKGROUND: There are no effective methods to cure Alzheimer disease (AD). Now, researches have shown that panax notoginseng saponins (PNS) play an important role in improving AD, but its mechanism is unclear.OBJECTIVE: To observe the protective effect of PNS characterized by removing blood stasis to stop bleeding and promoting blood circulation to relieve pain on pathological lesion of cholinergic neuron in rat with AD.DESIGN: Completely randomized grouping design and controlled study.SETTING: Neuroscience Institute of Guangxi Traditional Chinese Medical University.MATERIALS: This experiment was completed in the Chinese Herb Pharmacodynamic Laboratory of Guangxi Traditional Chinese Medical University between June 2003 and April 2005. A total of 90 health Wistar rats of clean grade and half gender were selected in this study. Among them, there were 75 old rats with 15 months old and 15 young rats with 3 months old. METHODS: This experiment was completed in the Chinese herb Pharmacodynamic Laboratory (Key Laboratory) of Guangxi Traditional Chinese Medical University between June 2003 and April 2005. ① A total of 90 healthy Wistar rats of clean grade and half gender were selected in this study. Among them, there were 75 old rats with 15 months old and 15 young rats with 3 months old. Fifteen young rats with 3 months old were regarded as young control group, and other 15 selected from 75 rats with 15 months old were regarded as old control group. The rest 60 rats were modeled on the basis of subacute injury induced by intravenous injection of D-galactose and bilateral cerebral Meynert basal nuclei injured by ibotenic acid. Parallel control was performed with saline on rats in young control group and old control group under the same condition. ② Two weeks later,survival modeling rats were divided randomly into 4 groups: model group,high-dosage PNS group, low-dosage PNS group and huperzine A group with 12 in each group. Rats in high-and low-dosage PNS groups were perfused with 200 and 100 mg/kg PNS (provided by Yunnan Yuxi Weihe Pharmaceutical Factory), respectively, once a day; rats in huperzine A group were perfused with 0.3 mg/kg huperzine A once a day for 4 weeks; rats in model group, young control group and old control group were perfused with the same volume of saline for 4 weeks. ③ After administration, pathological sections of brain tissue were cut, and immunologic-reaction activity of choline acetyltransferase (ChAT), morphological changes and numbers of positive neuron in cerebral sections were determined by immunohistochemistry analysis. ChAT immuno-positive neurons were analyzed with IBAS imaging analysis system to assay average area of section and average absorbance (A), and amount of ChAT immuno-positive neurons was calculated with microscope micrometer. ④ Measurement data were compared with single-factor analysis of variance.MAIN OUTCOME MEASURES: Effect of PNS on distribution of cholinergic neuron and ChAT content in cerebral tissue of AD rat models.RESULTS: A total of 75 old rats and 15 young rats entered the final analysis. ① Amount of ChAT immuno-positive neurons was the most, and the color was the deepest in young control group; amount of ChAT immuno-positive neurons was higher in high-dosage PNS group than that in huperzine A group and model group; ChAT immuno-positive neurons were smaller in model group than those in other goups, and the amount was decreased obviously. Axis-cylinder and dendrite of soma were shortened remarkably. ② Amounts of ChAT immuno-positive neurons in basal forebrain were less in model group than those in other groups (P ＜ 0.05), less in lowdosage PNS group, huperzine A group and model group than those in old control group (P ＜ 0.05), less in huperzine A group and model group than those in high- and low-dosage PNS group (P ＜ 0.05), and less in young control group than those in other groups (P ＜ 0.05). The mean A value of ChAT immuno-positive neurons in basal forebrain was similar to amounts in each group. Average area of section of ChAT immuno-positive neurons in basal forebrain was smaller in low-dosage PNS group and model group than that in young control group (P ＜ 0.05), and differences in other groups were not significant (P ＞ 0.05).CONCLUSION: PNS plays a protective role in pathological lesion of cholinergic neuron in AD rat models. PNS can also increase survival amount and quality of cell and increase content and activity of ChAT so as to protect and improve central cholinergic system, and inhibit aging and dementia through improving and repairing injured cholinergic neurons.

[Objective] To observe the anti-aging actions of total saponins of Radix Notoginseng, i.e., Panax Notoginseng saponins (PNS) on rats with Alzheimer's Disease (AD). [Methods] Among 90 Wistar rats, 15 rats aged 3 months were allocated to the youth group, 15 aged 15 months to the aged group, and other 60 aged 15 months were given with intraperitoneal injection of D-galactose and injection of ibotenic acid into bilateral Meynert nucleus basalis to establish the models of AD. After then, the surviving model rats were randomized into four groups: model control, high-dose PNS (200mg?kg-1?d-1), low-dose PNS (100 mg?kg-1?d-1) and huperzine A (0.3 mg?kg-1?d-1). Except the model group, the youth group and the aged group were given the same amount of normal saline by gavage, the other groups were treated with the designed drugs respectively for 4 weeks. After treatment, serum levels of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), triglyceride (TG) and cholesterol were detected. [Results] High- and low-dose PNS increased the serum levels of SOD, GSH and CAT, the differences being significance as compared with the model group (P

OBJECTIVE:To study the protective effect of Yulangsan polysaccharide(YLSPS) on acute alcoholic hepatic injury in mice.METHODS:50% alcohol at a dose of 10 mL?kg-1 was administered (ig) to mice to establish acute alcoholic hepatic injury model.The activities of serum transaminase and superoxide dismutase(SOD) and the triglyeride(TGL) level were determined and a pathohistological study was performed. RESULTS:The activity of serum transaminase and the content of triglyceride in mice were significantly down-regulated by different doses of YLSPS,but the activity of superoxide dismutase in YLSPS-treated groups was significantly up-regulated and the number of fat droplets was reduced. Fatty degeneration in acute alcoholic hepatic injury model mice was significantly abated by high-dose and middle-dose YLSPS.CONCLUSION:The protective effect of YLSPS on alcohol-induced acute hepatic injury in mice was attributed to its action in lessening the effect of alcohol on lipometabolism.
