Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

OBJECTIVETo analyze the effects of three surgical operations in the treatment of Pilon fracture of Rüedi-Allgower type III, and put forward the best therapeutic method.
METHODSThe clinical data of 33 patients with Pilon fracture who received surgical operations (plaster immobilization group, 10 cases; distal tibia anatomical plate group, 11 cases; external fixation with limited internal fixation group, 12 cases) from October 2009 to January 2012 were analyzed. There were 5 males and 5 females, ranging in age from 24 to 61 years in the plaster immobilization group. There were 7 males and 4 females, ranging in age from 21 to 64 years in the distal tibia anatomical plate group. There were 7 males and 5 females, ranging in age from 23 to 67 years in the external fixation with limited internal fixation group. The Ankle X-ray of Pilon fracture after operation, ankle score, early and late complications were collected. Bourne system was used to evaluate ankle joint function.
RESULTSAfter 8 months to 3 years follow-up, it was found that three kinds of treatment had significant differences in the outcomes and complications (P < 0.05): the external fixation with limited internal fixation group got the best results. The number of anatomic reduction cases in the external fixation with limited internal fixation group (7 cases) and the distal tibia anatomical plate group (8 cases) was more than the plaster immobilization group (2 cases). According to the ankle score, 8 patients got an excellent result, 3 good and 1 poor in the limited internal fixation group ,which was better than those of distal tibia anatomical plate group (5 excellent, 4 good and 2 poor) and the plaster immobilization group (3 excellent, 4 good and 3 poor). The number of early and late complications in the external fixation with limited internal fixation group was more than those in the plaster immobilization group and the distal tibia anatomical plate group (P< 0.05).
CONCLUSIONTreatment of external fixation with limited internal fixation in the treatment of Pilon fracture of Rüedi-Allgower type III is effective and safe.

OBJECTIVETo evaluate the feasibility and curative effect of thymectomy for myasthenia gravis (MG) by video-assisted thoracoscopic surgery (VATS) through right anterior-lateral approach.
METHODSFifty-six patients of MG were treated with thoracoscopic thymectomy and mediastinal fat dissection through right anterior-lateral approach from August 2001 to October 2007. The feasibility, safety, complication and remission for MG were retrospectively analyzed.
RESULTSFifty-five operations were completed by VATS. The mean operative time and blood loss were (96.2 +/- 52.1) min and (68.7 +/- 21.4) ml, respectively. The brachiocephalic vein injury by the electric coagulator occurred in two cases and one of them performed thoracotomy for homeostasis, the other performed ligation. The postoperative pathology showed hyperplasia in 38 cases, atrophy in 5 cases, thymoma in 12 cases and cyst of thymus in 1 case. And the operative complication included one myasthenia crisis (1.8%) at the third day and one death (1.8%) at the eighth day because of postoperative hemorrhage. The average length of stay was (7.9 +/- 2.9) d. All cases were followed up from one to seventy months. Eight (14.3%) of complete remission, 39 cases (69.6%) of partial remission and 7 cases (12.5%) of no change were found. The total effective rate was 83.9%.
CONCLUSIONSThoracoscopic thymectomy through right anterior lateral approach is technically feasible, safe and minimally invasive. It has a high remission rate for MG.

OBJECTIVETo better understand the clinical feature of viral gastroenteritis attributed to noroviruses and to summarize the experience on an outbreak of acute gastroenteritis through rapidly colleting and confirmation of related information regarding to noroviruses in hospitals.
METHODSInformation on an outbreaks involving 18 patients with acute gastroenteritis in one hospital regarding its epidemiological and clinical features and to perform bacteria culture for stool specimens on every patient. On 7 patients, rotavirus antigen were RNA tested together with norovirus nucleic acid were examined by ELISA and PAGE and RT-PCR.
RESULTS(1) Most of the patients were elderly with several chronic diseases. (2) Watery diarrhea (12/18, 66.67%) and few with mucous (3/18, 16.67%) were seen. Most stool examination was normal (10/18, 55.56%) but few stool specimen could be found with some leucocytes (3/18, 16.67%) and little occult blood (4/18, 22.22%). (3) All bacteria culture in stools showed negative. There was no rotavirus RNA identified but 3 specimen showed norovirus nucleic acid positive as 42.86% (3/7).
CONCLUSIONNorovirus was one of the important pathogens causing acute gastroenteritis outbreaks in hospitals attacking elderly with several chronic diseases in particular. Surveillance program targeting elderly inpatient with diarrhea should be enhanced, especially in autumn and winter.

OBJECTIVEThis study estimated the investment in child development from three aspects-public health, public education, and family investment to establish the level of investment, to provide reference information for government decision making and to provide international comparisons.
METHODSPublic investment in health was measured with macro data related to public health spending and child development in government expenditure. Public education investment was based on basic education data. Family investment evaluation was based on per capita family consumer spending data in different age groups to estimate the input for child development.
RESULTSBoth public health investment level and the proportion of GDP rose for all age groups over time, but the overall investment level was still insufficient. Public investment in children's education has increased year by year, but the trends in all age groups are unbalanced with much lower investment in early childhood education. Private investment in children has increased over the period, but has declined as a percentage of GDP. International comparisons show that Chinas investment in child development is much lower than OECD countries.
CONCLUSIONThe private investment in child development was the main way in China, with public finance contributing only a small proportion. Given the poor international comparisons, the government needs to review the balance of public investment to redirect more towards the development of children under the age of six to their health and education.

BACKGROUNDTo investigate the prognostic significance and role of coagulation factor V (CFV) levels in clinical diagnostic criteria for severe hepatitis.
METHODSThe CFV level and prothrombin activity (PTA) were tested by turbidimetry for 129 times in 58 patients with severe hepatitis. Comparative studies and clinical significance of CFV and PTA were analyzed by SPSS and SDAS softwares.
RESULTS1. The levels of CFV and PTA were 15.3%+/-9.7% and 23.5%+/-10.0%, respectively, at the onset of severe hepatitis. 2. The mortality of severe hepatitis gradually increased with the gradual decrease of CFV or PTA during the most severe stage of the illness (P=0.000). 3. The levels of CFV and PTA decreased continually and rapidly in patients who died but gradually increased in survivors. The decrease or increase of PTA preceded that of CFV on the exacerbation or convalescent stage. 4. Hepatic encephalopathy occurred in 14 cases (24.14%). In 10 cases, it occurred in the terminal stage of the illness, far later than the time of the decrease of CFV. 5. The level of CFV was closely related to PTA (the correlation coefficient was 0.812), the level of CFV was almost consistent with that of PTA.
CONCLUSION1. The level of CFV is an important prognostic indicator in severe hepatitis and is more specific than PTA. 2. Simultaneous determination of CFV and PTA may be helpful in earlier and more accurate diagnosis of severe hepatitis. 3. Possible use of CFV as one of the criteria for liver transplantation in patients with severe hepatitis should be studied.

OBJECTIVETo observe the influence of therapy with Chinese medicine Lirukang Granule (, LRKG) combined with psychological intervention on anxiety states and sex hormones in patients with cyclomastopathy and menoxenia.
METHODSA total of 470 subjects were randomly assigned to three groups by the net-central randomization system, the treatment group (161 patients, treated with LRKG and psychological intervention), the Chinese medicine group (157 patients, treated with LRKG), and the psychological intervention group (152 patients, treated with psychological intervention). The dose of LRKG was 12 g three times per day; psychological intervention included establishing relations, cognitive intervention and psychological persuasion, 30-40 min per session, once a week. The therapy duration for all groups was three months. The efficacy was compared and anxiety state/State-Trait Anxiety Invertory (STAI) scoring was measured before and after treatment. The serum estradiol (E2), progesterone (P), prolactin (PRL) and follicle stimulating hormone (FSH) levels of 60 patients selected randomly from each group during the luteal phase were measured before and after treatment, and a group of 20 healthy women were evaluated for comparison. A follow-up was arranged for one year after treatment.
RESULTSThirty subjects were lost to follow-up. (1) Comparison of efficacy: the markedly effective rate and the total effective rate of the treatment group were 86.67% (131/150) and 98.00% (147/150), respectively; of the Chinese medicine group, 64.58% (93/144) and 90.27% (130/144), respectively; and of the psychological intervention group, 0% (0/146) and 3.42% (5/146), respectively. The markedly effective rate and the total effective rate in the treatment group were significantly higher than those in the Chinese medicine and psychological intervention groups (P < 0.05). (2) Comparison of STAI scoring: STAI scoring was decreased dramatically in the treatment group after treatment compared with that of the Chinese medicine group (P < 0.01), but there was no significant difference compared with the psychological intervention group. (3) Comparison of levels of sex hormones: E2, P, PRL and FSH of the three patient groups were disordered before treatment, and significantly different from healthy women (P < 0.01). After treatment, the levels of P and FSH of the treatment group were significantly increased (P < 0.01), E2 and PRL were significantly reduced, which were also significantly decreased compared with the psychological intervention groups (P < 0.01). (4) FOLLOW-UP: the markedly effective rate and the total effective rate of the treatment group remained higher than those of the other two groups after one year of treatment (P < 0.05). (5) Adverse reactions: no obvious adverse reactions were found among the three groups.
CONCLUSIONSTherapy with Chinese medicine combined with psychological intervention was effective for short-term and long-term treatment of cyclomastopathy and menoxenia. The mechanism might be related to the regulation of sex hormones.
