OBJECTIVETo investigate the safety, medium-term and long-term efficacy of transradial percutaneous coronary intervention for unprotected left main coronary artery lesions with 6 French guiding catheter.

METHODSSixty-one patients with unprotected left main coronary artery lesions were treated by 6 French transradial percutaneous coronary intervention between January 2008 and December 2009. The mean age of patients was (66.03 ±10.02)years (44-87). Among 61 cases, 40 had hypertension and 14 had diabetes mellitus; 22 had a history of smoking. The average left ventricle ejection fraction was (62.96 ±12.15)% (range: 28-86) and the average plasma creatinine level was (82.92 ±18.30)μmol/L (range: 44-130). The major adverse cardiac events (MACE) after the procedure were evaluated.

RESULTSProcedural success was achieved in all cases. A total of 67 stents were implanted. No in-hospital death occurred. Mean clinical follow-up period was (26.25 ±5.92) months (range: 19-44 months). MACE developed in 6 cases (9.8%) during the follow-up period, including 2 death (3.3%) and 4 case of target lesion revascularization (6.6%). Compared with low-risk group (SYNTAX score<33), MACE was increased in the high-risk group (SYNTAX score>32).

CONCLUSION6 French transradial percutaneous coronary intervention for patients with unprotected left main coronary artery lesions is safe and feasible procedure with desirable medium-and long-term outcomes.

OBJECTIVETo study the effect and mechanism of ginsenoside Rg1 on the spatial learning-memory ability in rats with Alzheimer's disease after transplanted with bone marrow mesenchymal stem cells (BMSCs).

METHODSUsing digital randomization table method, seventy-five male SD rats were divided into the bilateral FF transection model group (as the model group: ambi-hippocampal fimbria-fomix transected), the sham-operative control group (the SOC group: receiving the same modeling process as the model group, but without ambi-hippocampal fimbria-fomix transected), the ginsenoside Rg1 treatment group (as the treatment group: Two weeks after modeling ginsenoside Rg1 was peritoneally injected at the dose of 5 mg/kg, once daily for four weeks in total), the BMSCs transplanted treatment group [as the control group: Two weeks after modeling every rat received transplantation of BMSCs (10 microL, 1 x 10(6) cells)], and the ginsenoside Rg1 + BMSCs treatment group (as the combination group: They received both transplantation of BMSCs and peritoneal injection of ginsenoside Rgl). The spatial learning-memory ability of rats was detected by Morris water maze and the escape latency (s) was recorded, mRNA expression of nerve growth factor (NGF) was detected using Real-time PCR.

RESULTSSix weeks after the hippocampal fimbria-fomix (FF) transection, the escape latency o feach medication group was obviously shorter than that of the model group, and the spatial learning-memory ability of dementia rats was somewhat improved. The spatial learning-memory ability of rats in the combination group was (29.95 +/- 2.03) and the mRNA expression level of NGF was (1.13 +/- 0.15), better than those in the BMSCs group (44.36 +/- 1.43, 0.78 +/- 0.09, P<0.05).

CONCLUSIONSGinsenoside Rg1 could strengthen the spatial learning-memory ability in dementia rats after transplanted with BMSCs. Its mechanism might be possibly correlated with up-regulating mRNA expression of NGF in basal forebrain after BMSCs transplantation.

Objective To investigate the better regimen of combined cyclophosphamide pulse therapy with corticosteroids in the treatment of Pemphigus. Methods Intravenous cyclophosphamide was given weekly in a dosage of 600 mg to those Pemphigus patients whose conditions couldn't be improved by corticosteroids (oral prednisone 1.2～1.5 mg/kg/d) alone. Results Ten patients with Pemphigus received weekly cyclophosphomide therapy in addition to corticosteroid. Patients conditions improved quickly, without side effects. Conclusions Cyclophosphamide weekly pulse therapy combined with corticosteroids is a good regimen in the treatment of Pemphigus.

OBJECTIVETo explore the role of macrophage colony-stimulating factor (MCSF) in the pathogenesis of preeclampsia.

METHODSBy ELISA method, MCSF concentrations were determined in serum samples obtained from 39 patients with preeclampsia and 40 normal pregnant women as controls. The concentrations of serum MCSF were compared between preeclampsia and normal pregnancy, and between early-onset and late-onset preeclampsia.

RESULTSerum MCSF concentrations were significantly higher in preeclamptic women than those in controls (431.0 kIU compared with 179.1 kIU, P<0.001). There were no significant differences in serum MCSF levels between early-onset and late-onset preeclampsia (P>0.05). Serum MCSF was not correlated with maternal age, gestational age, and placenta weight (P>0.05 for all).

CONCLUSIONIncreased level of serum MCSF is an important indicator of preeclampsia and it may play a role in the pathogenesis of the disease.

OBJECTIVEIn order to compare the efficacy of two kinds of membrane plasma separator on the treatment of patients with severe hepatitis B.

METHODS63 cases suffering from chronic severe hepatitis B were divided into two groups, 25 cases were treated with plasma exchange using Evacure-4A membrane plasma separator (A group) or 38 cases were using PS-06 membrane plasma separator (B group). Both of them also were treated with similar basic medical treatment. The level of serum total bilirubin, non-conjugated bilirubin, prothrombin time and albumin were tested at baseline and the end of the treatment with PE.

RESULTSEvacure-4A and PS-06 membrane plasma separators can effientively remove bilirubin, the levels of serum total bilirubin, non-conjugated bilirubin of all patients were significantly decreased after treated with PE. In A group, the level of serum total bilirubin, non-conjugated bilirubin decreased from (464.2+/-193.8)micromol/L to (279.4+/-158.7)micromol/L, (293.5+/-129.1)micromol/L to (175.5+/-106.7)micromol/L (t=5.45, 10.36, P<0.01) respectively. In B group, the level of serum total bilirubin, non-conjugated bilirubin decreased from (493.2+/-126.9)micromol/L to (299.7+/-96.5)micromol/L, (300.2+/-74.3)micromol/L to (171.5+/-53.1)micromol/L (t=5.17, 12.04, P<0.01) respectively. The level of serum albumin increased after treated with PE in A and B groups, to contrast with PS-06, the increasing percentage of albumin was higher when the patients were treated with PE using Evacure-4A membrane plasma separator [(8.3+/-0.7) % vs. (3.4+/-9.3) %, t = 2.76, P<0.01].

CONCLUSIONEvacure-4A membrane plasma separator may be better than PS-06 membrane plasma separator on the treatment of patients with chronic severe hepatitis B.

OBJECTIVETo observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.

METHODSA total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.

RESULTSThe total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).

CONCLUSIONCDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.
