Objective To observe the clinical efficacy and security of anti-tuberculosis combined with highdose methylprednisolone in treatment of advanced tuberculous meningitis.Methods 77 patients with advanced tuberculous meningitis in our department were randomly divided into the observation group(39 cases)and the control group (38 cases).All of the patients were given initiate antiphthisie treatment,the control group were added dexamethasone,20mg/d,iv drip,then was maintained after improved;the observation group were added high-dose methyprednisolone(500mg/d)by intravenous injection for five days,then was given methyprednisolone 80mg/d to maintain.Two groups were treated with hormone no more than three months.Then the clinical efficacy and adveme reaction were compared.Results The observation group:32 cases of healing,6 cases of effective,1 case of inefficient,the total effective rate was 97.4%and the control group were 22,8,8,78.9%;the difference of total effective rates in the two groups was statistically significant(x2=7.57,P＜0.05).The time of consciousness restoration and defevesence,the white blood cell count,protein chloride and glucose content of cerebrospinal fluid of the observation group were(2.7±1.3)d,(13±5)d,(112.37±27.57)×106/L,(3.04±0.82)g/L,(32.7±6.4)mmol/L and(1.67±0.65)mmol/L;and the control group were(5.2±2.4)d,(19±6)d,(93.74±20.18)×106/L,(1.92±0.64)g/L,(25.4 ±5.2)mmol/L and(1.04±0.34)mmol/L,the difference was statistically significant(t=5.70,4.77,3.88,6.67,5.48,5.31,P＜0.01);The difference of adverse reaction rate between the two groups was not statistically significant (P＜0.05).Conclusion The clinical efficacy of anti-tuberculosis combined with high-dose methylprednisolone in treatment of advanced tuberculous meningitis was better and had advantages in improving symptoms and signs without enhancing the rate of adverse reaction and it was worth to promote in clinical.

Objective To describe the status of resilience and self-care behaviors in chronic heart failure patients and to explore the relationship between resilience and self-care behaviors. Methods It was a cross-sectional survey. The Connor-Davidson Resilience Scale, the self-care behaviors with heart failure questionnaire and the demographic scale were delivered to 150 chronic heart failure patients in Shanghai Changhai Hospital. Results The score of self-care behaviors was (2.63 ± 2.01) points for chronic heart failure patients. The resilience score was (57.56 ± 8.51) points. The resilience was significantly related to the self-care behaviors(r=0.427, P<0.01), and which explained 32.4%of the total variation. Conclusions The chronic heart failure patients have poor self-care behaviors and resilience. More attention should be paid and more action be taken to improve the resilience, then improve the self-care behaviors of patients.

OBJECTIVE: To analyze the situation and the related problems of Chinese patent drugs including toxicity components used in pediatrics, and to provide the suggestion for the development of Chinese patent drugs for pediatrics. METHODS: 264 Chinese patent drugs which were used in pediatrics were collected from national drug standards, and compared with toxicity drug list. The utilization of toxicity drugs were analyzed statistically. RESULTS: About half of Chinese patent drugs for pediatric included toxicity components. Major problems are complex resource of toxicity components, overdose of toxicity components, single disease and pattern, unscientific determination of amount, etc. CONCLUSION: The in-depth study of Chinese patent drugs requires perfecting national drug standards, to developing more rigorous special approval requirements, to establishing the re-evaluation system and to eliminating unsuitable category of Chinese patent drugs.

RESULTS: The effectiveness rates of cardiac function improvement were 93.9 % and 76.7 % in milrinone group and dabutamine group, respectively (P

Triple-negative breast cancer (TNBC) is a subtype of breast cancer known for the poor prognosis due to its strong invasiveness, high recurrence rate, and lack of effective treatment. Therefore, there is an urgent need to find targeted therapy for TNBC. Cathepsin A (CTSA) is an acidic serine carboxypeptidase that is highly expressed in various tumor tissues. However, the role and molecular mechanism of CTSA in TNBC are still unclear. This study found that the expression of CTSA was upregulated, and the high expression of CTSA was positively correlated with the poor prognosis of TNBC. The results further showed that knocking down CTSA inhibited the proliferation, invasion, and colony formation of TNBC cells, improved drug sensitivity of cells, and inhibited the progression of TNBC. Mechanistically, CTSA inhibited the ubiquitination and degradation of the promyelocytic leukemia protein (PML) protein by blocking the interaction between PML and its E3 ubiquitin ligase RNF4, thus maintaining the stability of PML nuclear bodies (PML-NBs). The inhibitor of CTSA had a positive therapeutic effect on inhibiting the characteristics of TNBC stem cells. In conclusion, this study demonstrates that inhibiting CTSA to decrease the stability of PML protein may be a promising therapeutic strategy for TNBC. All animal experiments in this experiment were approved by the Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences and Peking Union Medical College (approval number: IMB-20240326D502).

OBJECTIVETo investigate the effect of allicin in inhibiting insulin-induced vascular smooth muscle cell (VSMC) proliferation and migration.

METHODThe tissue explant method was adopted to culture rat's aVSMCs, and the immunofluorescence method was used to identify α-SMA. Cells from the third to fifth generations were selected in the experiment The insulin-induced VSMC model was established. The experiment was carried out in five groups: the control group, the insulin group, the allicin group, the ERK inhibitors PD98059 group (20 μmol · L(-1)) and the PD98059 + allicin group. VSMCs' proliferation was determined by CCK8 colorimetric method, while its migration was detected by cell counting; The western blotting was used to detect total ERK, Phospho-ERK, PCNA protein's expression.

RESULTPrimary cultured VSMCs grew well in the spindle shape under the lightmicroscope, with peak and valley. α-SMA immunofluorescence results showed that the cultured cells had typical VSMCs' features. Insulin could stimulate VSMCs' proliferation and migration, with the best effect at the concentration of 100 nmol · L(-1). The pretreatment with allicin could significantly inhibit VSMCs' proliferation and migration induced by insulin in a dose-dependent manner. The pretreatment with PD98059 and allicin + PD98059 could inhibit VSMCs' proliferation and migration induced by insulin remarkably as well. Insulin could significantly accelerate VSMCs' expression of such proteins as p-ERK, PCNA. Contrarily, allicin could notably inhibit VSMCs' expression of such proteins as p-ERK, PCNA in a dose-dependent manner.

CONCLUSIONAllicin could significantly inhibit VSMCs' proliferation and migration induced by insulin, which may be related to the inhibition of the activation of ERK signal path.

Objective To investigate the changes of cesarean section rate and indications in different level hospitals of different areas in China during 2000 to 2009. Methods Literatures published in Chinese journals on variation of cesarean section rate and indications from 2000 to 2009 were analyzed. Cochran-Armitage test was used to analyze the trend. The differences of cesarean section rate between different areas or different level hospitals were analyzed by chi-square test.Results Forty-nine papers were enrolled in this study.Cesarean section rate had risen from 2000 (32.1％,10 353/32 258) to 2009 (52.5％,3674/6992)(Z=-20.8267,P＜0.01).During 2000 to 2008,the average cesarean section rate of level one grade A hospital was 45.7％ (3754/8214),which was higher than 34.5％(25 015/72 507) in level three grade A hospital and 32.3％(28 140/87 121) in level two grade B hospital (P＜0.05,respectively).Except for level three grade A hospital,cesarean section rate had risen in the other two level hospitals during 2003 to 2008. The average cesarean section rate was 58.6％ (4982/8502) in northeast area during 2000 to 2007,which was higher than that of other areas (P＜0.01); and the average cesarean section rate was 27.5％ (12 264/44 595) in central China and 33.0％ (23 239/70 421) in southern China,which were lower than that of other areas (P＜ 0.01 ). Social factor,instead of dystocia,became the most important indication for cesarean section,and its proportion kept rising annually,from 11.3％ (1170/10 353) in 2000 to 27.1％(2094/7726) in 2008 and remained above 20.0％(5159/24 691) since 2004.The proportion of scar uterus rose from 6.7％(694/10 353) in 2000 to 12.5％ (459/3674) in 2009. Conclusions Cesarean section rate rises fast and its major indications had changed in China. It is suggested that special method should be taken to control the current situation.
