ObjectiveTo observe the effects of human IL-10 gene transfection on the mRNA and protein expressions of IL-1β and TNF-α in the penumbra area following focal cerebral ischemia-reperfusion injury in rats and to investigate its neuroprotective mechanism. MethodsRats were divided into four groups: normal control group, ischemic control group, empty plasmid group and human IL-10 gene transfected group. The mRNA and protein expressions of IL-1β and TNF-α in the penumbra area were detected by fluorescence real-time quantitative PCR and ELISA respectively. ResultsIn normal control group, ischemic control group, empty plasmid group and human IL-10 gene transfected group, the levels of protein expression of TNF-α in penumbra area were(0.66±0. 04) ,(1.16±0.26),(1. 155±0. 26)ng/g and(0. 84±0. 05)ng/g, and the levels of protein expression of IL-1βin penumbra area were(0.37±0.05), (1.25±0.39), (1.21±0.57) ng/g and(0.62+0.05)ng/g, respectively. Compared with normal control group, the levels of protein expression of TNF-α and 1L-1β were significantly higher in other three groups(all P＜0. 01), and lower in human IL-10 gene transfected group than in ischemic control group and empty plasmid group(all P＜0. 01). In normal control group, ischemic control group, empty plasmid group and human IL-10 gene transfectedgroup, the levels of mRNA expression of TNF-α in penumbra area were 1.00 ±0.53,9.42±1.83,9.69±1.96 and 3.53±1.09, and the levels of mRNA expression of IL-1β in penumbra area were 1.00 ±0.51,27. 81±4.84,23.96 ± 4.90 and 13.55± 4.45, respectively. Compared with normal control group, the levels of mRNA expression of TNF-α and IL-1β were significantly higher in other three groups(all P＜0. 01), and lower in human IL-10 gene transfected group than in ischemic control group and empty plasmid group(all P＜0. 01). ConclusionsThe human IL-10 gene transfection may play an protective effect on cerebral ischemia through inhibiting mRNA and protein expression of IL-1β and TNF-α in the penumbra area following focal cerebral ischemia-reperfusion in rats.

OBJECTIVETo compare clinical therapeutic effects of abdominal acupuncture and traditional acupuncture on cervical spondylosis (CS).

METHODSSixty-two cases of neck or nerve-root type CS were randomly divided into an observation group (n=32) treated by abdominal acupuncture at Zhongwan (CV 12), Guanyuan (CV 4) and others, and a control group (n=30) treated by traditional acupuncture at Fengchi (GB 20) and cervical Jiaji (EX-B 2), etc.. Simplified McGill Pain Questionnaire (MPQ) and clinical therapeutic effects were served as the objective indexes. Their clinical therapeutic effects were compared after the first session of treatment, at the end of therapeutic course and 3 months after the end of treatment.

RESULTSThe two groups had a same effective rate of 100.0%. All items of MPQ in these two groups after treatment and 3 months after the end of treatment significantly improved, and in the observation group the differences in the PRI feeling score before and after the first treatment, and the difference of the total PRI scores after the first treatment, at the end of therapeutic course and 3 months after the end of treatment significantly improved as compared with the control group (P < 0.05).

CONCLUSIONAbdominal acupuncture can better reduce the pain of the patient caused by CS, with transient pain-alleviating effect, but whether or not the clinical therapeutic effect of abdominal acupuncture is better than the traditional acupuncture still can not be proved.

OBJECTIVETo compare the long-term effect and safety of tacrolimus (FK506) and cyclosporine (CsA) in kidney transplant (KT) recipients carrying hepatitis B Virus(HBV).

METHODSA total of 109 patients with HBV were randomized into FK506 group (52 cases) and CsA group (57 cases) after KT, and a 2-year-long follow-up of the patients was conducted to record the patient and graft survival, incidence of acute graft rejection and postoperative liver function.

RESULTSThe 2-year patient/graft survival was 86.0%/73.7% and 94.2%/90.3% in CsA and FK506 groups, respectively (P<0.05), with incidence of acute rejection of 10.5% and 9.6% (P>0.05), and rate of abnormal liver function of 26.3% and 15.4% (P<0.05), respectively. Eight patients (14.4%) in CsA group required a drug conversion but none in FK506 group. The drug conversion resulted in significant reduction of ALT/AST level from 255.13+/-31.38/201.88+/-21.25 U/L to 31.25+/-11.50/25.13+/-9.68 U/L (P<0.01).

CONCLUSIONFor HBV-carrying renal transplant recipients, FK506 as the primary choice of immunosuppressant can be more effective and safer than CsA.

[Objective]To explore the distribution and expression changes of tight junctional protein JAM-1 in rat models after intracerebral hemorrhage (ICH) and their significance.[Methods]One hundred and twenty-eighty healthy male SD rats were randomly divided into normal control group (n=16) and ICH group (n=112),and the ICH models were induced by stereotactically injecting 75 uL autologous blood into the right caudate nucleus.Seven time points after ICH (6,12,24 and 48 h,and 3,7 and 14 d after ICH,16 rats for each time point) were chosen.BBB permeability was evaluated by Evans blue dye extravasation.The distribution and expression of JAM-1 were detected by immunofluorescence and real-time quantitative PCR.[Results] As compared with that in the normal control group,BBB permeability in the ICH group significantly increased at 24 and 48 h,and 3 and 7 d after ICH (P＜0.05).JAM-1 expression decreased at blood vessels at 12,24 and 48 h after ICH,and JAM-1 expressed at the circulatingleukocytes3 dafterlCH,and abundant JAM-1 positive cells around hematoma were noted in the ED-l-positve macrophages 7 d after ICH.JAM-I mRNA significantly decreased at 12,24 and 48 h after ICH,and significantly increased 7 d after ICH as compared with that in the normal control group (P＜0.05).[Conclusion] JAM-1 experssion changes not only participate in regulation of BBB permeability but also play roles in inflammatory insult after ICH.

To evaluate the inhibitory effects of long antisense RNA on HBV replication in HepG2.2.15 cells. The coding region of HBV S gene was cloned into pTARGET vector in sense and antisense orientations and the recombinant plasmids were transfected into HepG2.2.15 cells which were divided into HBS2 (antisense RNA) group, HBS4 (sense RNA) group and control group. HBsAg and HBeAg in the culture supernate were detected by ELISA. The HBV DNA in the supernate was quantified by real-time PCR. After treatment, the levels of HBsAg in HepG2.2.15 cell supernatants of three groups were 0.621+/-0.027, 3.399+/-0.018 and 2.232+/-0.187 respectively; the levels of HBeAg were 0.749+/-0.019, 1.548+/-0.025 and 1.570+/-0.044 respectively and the levels of HBV DNA were 1.597+/-0.082, 3.381+/-0.297 and 3.610+/-0.063 respectively. The expressions of HBsAg and HBeAg and the HBV DNA level in HBS2 group were remarkably reduced as compared to the control (Z = -2.309, P value is less than 0.05); whereas the sense plasmid transfection (HBS4) did not affect HBeAg (Z = -0.866) and HBV DNA (Z = -1.155) levels in the culture supernate but slightly increased the HBsAg level (Z = -2.309). Antisense RNA might be a useful tool to repress HBV replication.

OBJECTIVETo study the pathology, diagnostic and therapeutic method of primary pigmented nodular adrenocortical disease (PPNAD).

METHODSThe data of 5 cases of PPNAD were analyzed retrospectively. Among the 5 cases, 2 were male and 3 were female. The range of age was from 12 to 53 years. All the 5 cases had symptoms of Cushing syndrome. The diagnose depended on the results of endocrine exams, ultrasound, CT, MR and pathological reports. All patients received operation of unilateral adrenalectomy. The therapeutic effects were determined by post-operative results, which concluded clinical symptoms and endocrine exams.

RESULTSThe follow-up time was from 4 months to 3 years. All patients' symptoms of Cushing syndrome were relieved in 6 months after operation. The endocrine exam was normal in one case and obvious improved in the other four cases. Up to now, one patient drop out of the follow-up, the other 4 cases had no evidence of recurrence.

CONCLUSIONPPNAD is a rare type of Cushing syndrome. Diagnose depends on endocrine exams and pathological results. Operation is the effective method for the disease.

OBJECTIVETo compare the hemodynamic responses to nasotracheal intubation with Glide Scope video-laryngoscope (GSVL), Macintosh direct laryngoscope (MDLS), and fiberoptic bronchoscope (FOB).

METHODSSixty patients, with American Society of Anesthesiologists (ASA) physical status I - II, aged 18- 50 years, and scheduled for elective plastic surgery under general anesthesia requiring nasotracheal intubation, were randomly allocated equally to GSVL group, MDLS group, and FOB group. After the routine anesthesia induction, nasotracheal intubation was performed with the GSVL, MDLS, and FOB, respectively. Noninvasive blood pressure (BP) and heart rate (HR) were recorded before (baseline values) and after anesthesia induction (postinduction values), at intubation, and subsequently at an interval of every 1 minute for a total of five minutes. The maximum and minimum values of BP and HR during the observation period were also noted. The rate pressure product (RPP) at each measuring time point was calculated. The areas under effect-time curve (AUE) of hemodynamics were calculated by time as X-axis and changes of BP and HR during the observation as Y-axis.

RESULTSAll the three groups were similar in the demographic data and intubation time. After anesthesia induction, BP and RPP in all the three groups decreased significantly compared to baseline values (P < 0. 05), while HR had no significant change. After nasotracheal intubation, BP, HR, and RPP in all three groups were significantly higher than the postinduction values (P < 0.05). In the FOB group, BP, HR, and RPP at intubation significantly increased when compared with the baseline values (P < 0.05). In the MDLS group, HR at intubation, and maximum values of diastolic blood pressure (DBP), mean arterial pressure (MAP), HR, and RPP during the observation were significantly higher than the baseline values (P < 0.05). In the GSVL group, all hemodynamic parameters at intubation and after intubation were not significantly different from the baseline values. BP, HR, and RPP at intubation, and the incidences of HR more than 100 bpm during the observation were significantly higher in the FOB group than in the other two groups (P < 0.05). BP was not significantly different during the observation between the MDLS and GSVL groups, but HR and RPP at intubation and after intubation as well as AUE(HR) were significantly higher in the MDLS group than in the GSVL group (P < 0.05). AUE(HR) and AUE(SBP) were significantly lower in the GSVL group than in the FOB group (P < 0.05).

CONCLUSIONThe hemodynamic responses to nasotracheal intubation are most severe with FOB, followed by MDLS, and then GSVL.

The objective of study was to evaluate the efficiency and safety of bortezomib for the treatment of multiple myeloma. Bortezomib in combination with dexamethasone was administered as first-line treatment in all 7 newly diagnosed patients with multiple myeloma. The patients with refractory myeloma were treated with bortezomib in combination with dexamethasone or with other traditional agents such as mitoxantrone and thalidomide. The results showed that according to the EMBT criteria, out of 7 patients one achieved complete response (CR), five achived partial response (PR) and one achived minor response (MR). The 3 patients with refractory/relapsed myeloma achieved PR (2/3) and MR (1/3). The overall response rate (CR + PR) was 80%. The most frequent adverse events observed were thrombocytopenia in three patients, diarrhea and peripheral neuropathy in one respectively. In conclusion, bortezomib demonstrates efficiency in the treatment of new-diagnosed and refractory/relapsed multiple myeloma, and the side effects from treatment are acceptable and manageable.
