Objective To study the prevention and cure effect of immunoregulation therapy on postoperative infectious complications of calculous obstructive jaundice.Methods Prospective,randomized,blind and controlled clinical analysis of 40 patients conforming to the standard of calculous obstructive jaundice was carried out.The patients were divided into two groups at random.One was control group (n=20) with regular therapy,and the treatment group (n=20) with ulinastatin plus thymosin-α1 on the base of regular therapy for 1 week.The immunological indexes were determined before and after therapy on the 1st,3rd,5th、7th and 14th day,including the changes in lymphocyte count,CD14+ monocytes human leukocyte antigen (locus) DR (HLA-DR),and the incidence of postoperative infection were observed.Results The incidence of postoperative infectious complications in treatment group (10％) was remarkable lower than that in control group (30％,P＜0.01).There was significant difference between two groups (P＜0.05).After the 3rd,up to 14th day of therapy,the counts of lymphocyte and CD14+ monocytes HLA-DR were significantly higher than those in control group (all P＜0.05).Conclusions Immunoregulation therapy can improve the prognosis of obstructive jaundice patients in a period of 14 days of observation,and lymphocyte counts and CD14+monocytes HLA-DR were increased significantly,showing that immuno suppression can be ameliorated.Immunoregulation therapy could effectively prevent infectious complications of calculous obstructive jaundice.

To summarize and analyze literature about acupuncture and moxibustion embodied in Medline Database from 2000 to 2007, the articles in Medline PubMed Database were retrieved by different retrieval tactics on line, in combination with artificial statistical analysis on the literature data. Results indicate that among a total of 4 041 articles about acupuncture and moxibustion retrieved from Medline in the 8 years, 628 were published in Chinese and 3071 in English. These articles were involved in 836 journals, including 31 Chinese Journals. Eight hundred and forty-one articles were from China mainland, Beijing (176), Shanghai (136) and Tianjin (43) were the top 3 provinces and cities of literature numbers. It is showed that most acupuncture and moxibustion articles embodied in Medline are published in many foreign publications in English as main, but this situation has greatly changed after Zhongguo Zhenjiu and other journals were cited by Medline since 2006.

OBJECTIVETo explore the methods of isolation, cultivation, purification, identification of the fetal mice testis Leydig cell and to observe its biological characteristics in vitro.

METHODSLeydig cells were isolated by 0.03% collagenase (type I) from fetal mice testis and cultured in DMEM/F12 medium. The identity and purity of Leydig cell were assessed by 3beta-hydroxysteroid dehydrogenase delta4-delta5 isomerase (3beta-HSD). Cell viability was measured by trypan blue. Testosterone level in the medium of cultured Leydig cells was measured in various culture phases and cell density by radioimmunoassay.

RESULTSThe purity of Leydig cell was (45.10 +/- 1.66)% before culture, and (81.17 +/- 2. 32)% 72 h after culture. The level of testosterone secreted by Leydig cells could be detected in the medium and its level was associated with the density and time of cultured Leydig cells. The secretion capacity of testosterone by single Leydig cell decreased gradually during the culturing period.

CONCLUSIONThe fetal Leydig cells isolated from fetal mice testis have high purity. It can be cultured and kept the secretion ability of testosterone for a few days in vitro. This system can provide a valuable model for further study on the cellular function of the Leydig cells of fetal mice.

OBJECTIVETo explore the effect of dexmedetomidine combined electrical stimulation on cognitive function of neurosurgical diseases patients treated by extracerebral intervention.

METHODSTotally 122 patients with neurosurgical diseases who underwent selective intervention were randomly assigned to the observation group and the control group, 61 cases in each group. Patients in the control group recieved anesthesia by dexmedetomidine. Those in the observation group received electrical stimulation at Baihui (DU20), Yintang ( EX-HN3), and Neiguan (PC6) before dexmedetomidine anesthesia. The cognitive function of patients at preoperative day 1 and postoperative day 1 was respectively evaluated by Mini-Mental State Examinations (MMSE). Serum NSE, S-100β, IL-1β, IL-6, and TNF-α levels were detected in the two groups before intervention and immediately after intervention using ELISA.

RESULTSMMSE scores of two groups were significantly reduced at post-intervention day 1, as compared with one day before intervention. MMSE score of the observation group at post-intervention day 1 was (23.15 ± 1.87) points, significantly higher than that of the control group [ (19.34 ± 1.64) points , (P < 0.05)]. The postoperative cognitive dysfunction (POCD) incidence rate of the observation group was 16.4% (10/61), significantly lower than that of the control group [39.3% (24/61); P < 0.05]. Compared with before intervention, NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels of the two groups increased (P < 0.05). Post-intervention NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels were significantly lower in the observation group than in the control group (P < 0.05).

CONCLUSIONDexmedetomidine combied electrical stimulation could effectively prevent the occurrence of postoperative cognition, and reduce levels of NSA, S-100β, IL-1β, IL-6 and TNF-α.

OBJECTIVETo investigate the effects of Liuweidihuang Decoction on the proliferation and melanin synthesis of cultured human melanocytes in vitro.

METHODSMTT assay was used to assess the proliferation of cultured human melanocytes after treatment with Liuweidihuang Decoction, and NaOH assay was employed to determine melanin synthesis.

RESULTSLiuweidihuang Decoction at the concentration of 5%-15% did not affect the proliferation of the melanocytes (P>0.05), and the decoction at 20%-30% significantly inhibited the cell proliferation, especially at the optimal concentration of 30% (P<0.01). The decoction promoted melanin synthesis in the melanocytes at the concentration of 10%-15% with the optimal concentration of 15% (P<0.01) but failed to produce such an effect at 20%-30%.

CONCLUSIONLiuweidihuang Decoction exert a two-way regulation on the proliferation and melanin synthesis of cultured human melanocytes in vitro.

The implantation of an intravascular stent has become a widely used minimally invasive treatment for coronary heart diseases due to its minimal invasiveness and high efficiency.But the long-term outcomes are often compromised by in-stent restenosis (ISR),which severely restricts its practical effectiveness.In this paper,the formation mechanism of ISR was discussed,and the effects of mechanical environment on ISR were analyzed from the view of solid mechanics.The research progress of stent expansion in vessels with 4 different shapes,including straight vessel,tapered vessel,bifurcation vessel and curved vessel was reviewed.Moreover,the correlations between vessel stress and vessel shape change caused by stent expansion and ISR were reviewed.Finally,based on the influence of different vessel shapes on stent expansion,a multi-objective optimization design method was proposed to improve the stent expansion performance and reduce the occurrence of ISR.

The rate of antenatal corticosteroid application in extremely preterm infants is generally increasing.Although a large number of clinical trials have demonstrated that antenatal corticosteroids significantly reduce mortality and improve prognosis in extremely preterm infants, their application rates still vary widely among different countries and gestational age groups, and the applicability and safety of the clinical applications are controversial.In the treatment of extremely preterm infants in China, the clinical application of antenatal corticosteroids is not widespread.The current situation of antenatal corticosteroid application in extremely preterm infants at home and abroad is reviewed to provide a theoretical basis for the application of antenatal corticosteroid in extremely preterm infants in China.
