Objective To compare the clinical efficacy of multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage. Methods Sixty-six patients of basal ganglia hypertensive cerebral hemorrhage, with bleeding volume over 40 ml were divided into experimental group (36 cases) and control group (30 cases) by random digits table method. Patients in experimental group underwent multi-target puncture combined with routine intracerebroventricular treatment of intracranial pressure monitoring,and patients in control group underwent frontotemporal craniotomy and small hematoma decompressive craniotomy. The operation time, length of stay, hematoma evacuation rate, catheter drainage time, total amount of mannitol, Glasgow Coma Scale (GCS) scores 3 days after treatment, complication rate and 3-month Glasgow Outcome Scale (GOS) scores were recorded and compared between two groups. Results The operation time, length of stay, hematoma evacuation rate 1 day after treatment, and total amount of mannitol in experimental group were significantly lower than those in control group: (67.5±8.0) min vs. (109.3±9.6) min, (18.6±4.2) min vs. (23.3±5.9) min, (59.7±9.2)% vs. (80.4±11.6)%, (668.6±83.5) g vs. (1 430.4±107.1) g, P<0.01. The hematoma evacuation rate 3 days after treatment, catheter drainage time and GCS scores 3 days after treatment between two groups had no significant differences (P>0.05). The GOS scores in experimental group: 5 points (9 cases), 4 points (10 cases), 3 points (8 cases), 2 points(5 cases), and 1 point(4 cases). The GOS scores in control group: 5 points (4 cases), 4 points (4 cases), 3 points (7 cases), 2 points (9 cases), and 1 point (6 cases). Long curative effect in experimental group was better than that in control group (Z =2.318, P =0.020). The incidence of intracranial air in experimental group was significantly higher than that in control group: 27.8%(10/36) vs. 3.3%(1/30), P<0.05. Other complications had no significant differences between two groups (P>0.05). Conclusions Multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage has more advantages, including less trauma, wide surgical indications, short operation time and hospital stay, less postoperative mannitol, and decreased mortality rate. For older, patients with organ dysfunction, and patients who can not tolerate craniotomy, it is an effective treatment, and worthy of promotion.

Objective To study the effects of DHPs calcium antagonist Mn9202 and lacidipine on 5-HT、TH and 5-HTR of rat stomach fundus smooth muscle cells. Methods It's effects was investigated by using immunocytochemistry and image analysis of stom- ach fundus smooth muscle cells in culture and compared with cyprohetadine(antagonist of 5-HT). Results 5-HT、TH and 5-HTR im- munoreactive substances were existed in SFSMC. The results of image analysis indicated that the content of 5-HT. TH and 5-HTR were significantly lower when using Mn9202.lacidipine and cyprohetadine. Conclusion The results suggest that the rat stomach fundus smooth muscle cells possess 5-HT autocrine function, and DHPs calcium antagonist reduce the number of 5-HT receptor in the rat stomach fundus smooth muscle cells though the reduction of 5-HT sythesis, this results conform with cyprohetadine (antagonist of 5 - HT).

Aim To establish an allogenetic mouse skin trans-plant model,in order to provide a research model for immunosup-pressive drugs. Methods Skins from the ears of C57BL/6 mice were transplanted to the back of BALB/c mice and skin isografts ( BALB/c mice to BALB/c mice) were used as control. Cyclos-porin A( CsA) was used as a model compound to test the imm-nosuppresive effect on allogenetic graft rejection. Following the transplation and CsA treatment, the graft rejection score and graft skin survival rate were quantified. Four and nine days after transplantation,serum IL-4,IL-12 and IFN-γ levels were meas-ured using ELISA kits. Twelve days after transplantation, mice were sacrificed. The weight of spleen and thymus was obtained, and CD4 + and CD8 + population of spleenic T cells were ana-lyzed using flow cytometer. Histological features were assessed by hematoxylin-eosin( HE) staining of formalin-fixed, paraffin-em-bedded graft skins. Results After transplantion, the graft rejec-tion score increased and graft skin survival rate decreased gradu-allly. Serum IL-12 and IFN-γ levels of allograft mice increased markedly. Compared with those of isograft mice, mice with skin allograft displayed a significant increase in the percentage of the CD8 + T cell subpopulation. Remarkable inflammation, such as edema, inflammatory cell infiltration were observed in allograft mice. Compared with saline treated mice, CsA significantly re-duced the graft rejection score and improved survival rate of skin grafts. And also, CsA treated mice had smaller spleen and thy-mus. Mice that received high doses of CsA had significantly less CD8 + T cells than those treated with saline. Moreover, allograft skins in mice that received CsA had less inflammation. Conclu-sions Allogenetic mouse skin transplantation exhibits acute graft rejection. CsA can inhibit the rejection in a dose dependent manner.

Objective To investigate the clinical value of ventricular intracranial pressure monitoring in treatment of severe craniocerebral trauma with high intracranial pressure.Methods A retrospective analysis was conducted on forty cases of severe craniocerebral trauma with GCS score of 3-5 undergone bilateral decompressive craniectomy from October 2010 to January 2012.The patients were divided into three groups:Group A (12 cases received craniotomy after the placement of ventricular intracranial pressure probe) ; Group B (15 cases had craniotomy ahead of the probe placement) ; control group (13 cases had probe placement alone).Intracranial pressure control,dose and duration of administration of dehydrator and prognosis were compared among groups.Results Groups A and B showed a better result in aspects of controlling intracranial pressure within 15 mm Hg,dose and duration of mannitol treatment,and prognosis,as compared with control group (P ＜ 0.05).Furthermore,Group A had seven cases of severe disability or in vegetable state,but only three cases in Group B (P ＜ 0.05).Conclusion Ventricular intracranial pressure monitoring can effectively reduce intracranial pressure,raise treatment success rate and decline the use of mannitol in management of severe craniocerebral trauma.

Intestinal microflora is an important part of the organ-ism, promoting digestion and absorption of nutrients, maintaining intestinal normal physiological function, regulating immune sys-tem. Intestinal microflora maintains steady state under normal conditions, but intestinal microbiota dysbiosis occurs when surrounding environment c hanges, such as age, diet, obesity and other metabolic diseases as well as antibiotics. Many recent studies have found intestinal flora could cause a variety of disea-ses, and colon cancer is closely related with intestinal microbiota dysbiosis. Some researches suggest improving the intestinal flora dysbiosis can reduce the incidence of colon cancer and inhibit the growth and the worsening of colon cancer. However, under-lying mechanisms remain unknown. So this article summarizes the research progress on the development of colon cancer and in-testinal microbiota dysbiosis, in order to provide reference for re-search on intestinal flora and colon cancer treatment.

Objective To investigate the effects of damage control surgery (DCS) in the treatment of severe craniocerebral injury patients combined with multiple extremity fractures.Methods The clinical data of 128 patients with severe craniocerebral injury[Glasgow coma scale (GCS) scored 3-8] combined with multiple extremity fractures admitted from May 2011 to August 2015 were retrospectively analyzed by case-control study.There were 81 males and 47 females,with an average age of 37.3 years (range,19-77 years).The patients were treated with intracranial pressure monitoring in addition to the common administration.The patients were subdivided into two groups:87 patients treated with DCS concept as damage control group and 41 patients treated with non-DCS routine concept as control group.The DCS group received craniotomy and fracture fixation operation in stage Ⅰ with selective operation of open reduction and internal fixation.The control group received craniotomy and open reduction and internal fixation in stage Ⅰ.The postoperative intracranial pressure,operation duration,intraoperative blood loss,hospital stay and prognosis [Glasgow outcome scale (GOS)] were analyzed statistically.Results No intracranial infection was found in all patients during the treatment process.In damage control group,the postoperative intracranial pressure was normal in 44 cases (51％),which was significantly better than that in control group [8 cases (20％)] (P ＜ 0.05).In damage control group,operation duration [(150.1 ± 12.4)minutes],intraoperative blood loss [(270.6 ± 15.3)ml],and hospital stay [(29.7 ± 9.3) days] were significantly shortened compared with control group,whose operation duration,intraoperative blood loss and hospital stay were (270.6 ± 9.8) minutes,(460.2 ± 17.5) ml,and (34.4 ± 6.2) days,respectively (P ＜ 0.05).The GOS rating of damage control group (70％) was notably higher than that in control group (42％) (P ＜ 0.05).Conclusion For severe craniocerebral injury patients combined with multiple extremity fractures,the application of DCS contributes to control of postoperative intracranial pressure,which can also shorten the duration of hospitalization and improve prognosis.

OBJECTIVETo observe the effects of oral administration of guanxin II decoction (GX II) on cardiovascular function, especially on the dynamics of coronary blood flow in healthy males.

METHODSChanges of heart rate, diastolic pressure, systolic pressure, left ventricular ejection fraction (LVEF), E peak, A peak, E/A value of mitral flow, diastolic peak velocity (Vmax) and diastolic flow velocity time integrals (VTI) of left anterior descending coronary artery (LAD) in 11 healthy male subjects were measured before and after oral administration of GX II, using non-invasive echocardiogram.

RESULTSCompared with those before GX II administration, the changes after administration in heart rate, systolic pressure, diastolic pressure, LVEF, E peak, A peak and E/A value, were insignificantly different (P>0.05), but the Vmax and VTI significantly increased at 30 min, 60 min, 90 min and 120 min after GX II administration (P<0.05).

CONCLUSIONTo increase the coronary blood flow is possibly one of the mechanisms of GX II in treating coronary heart disease and angina pectoris.
