Cathepsin S is one of the cathepsins that distributes generally at lysosomes of histiocyte in humans body.It has variety of actions when it is unbalancing,including promote inflammation,atherosclerosis,diabetes and obesity,etc.Studies in recent years have demonstrated that there are certain correlations of adiponectin with vascular risk factor and cerebrovascular disease.

Objective To explore the expressions and significances of apoptotic modulating genes Fas and Bcl-2 mRNA in peripheral blood monocytes(PBMC)of patients with myasthenia gravis (MG). Methods The levels of Fas and Bcl-2 mRNA in PBMC were detected by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) in 44 patients with MG as well as 30 healthy donors served as a normal control (NC).Results (1) The level of Fas mRNA in MG group was no significantly difference compared with NC group. The level of Bcl-2 mRNA in MG group was higher than that in NC group(P

Objective To determine whether rapid and delayed tolerance to focal cerebral ischemia can be induced by pretreatment with single electroacupuncture (EA) at the Baihui acupoint in rats. Methods Forty-eight healthy male SD rats weighing 280-320 g were randomly divided into 6 equal groups with 8 animals in each group: (1) control group received no pretreatment before focal cerebral ischemia; (2) electroacupuncture group was further divided into 5 groups in which EA was performed at Baihui acupoint and electric stimulation was maintained for30min0.5 h(EAl),1 h(EA2),2 h(EA3),3 h(EA4) or 24 h(EA5) before focal cerebral ischemia. The animals were anesthetized with isoflurane and spontaneous respiration was maintained. Middle cerebral artery occlusion (MCAO) was performed using a nylon thread with a rounded tip inserted into internal carotid artery and thread cranially until resistance was felt. MCAO was maintained for 2 h, then the nylon thread was withdrawn to allow reperfusion . After MCAO the animals were observed for 24 h for neurological deficits which were assessed by a 0-5 grade scoring system (0 = no deficit, 5 = death) . The animals were then sacrificed and brain was immediately removed for estimation for the size of cerebral infarction. Results There were significantly less neurological deficits and the size of infarction was smaller in group EA3 and EA5 than those in control group. There were no significant differences in neurological deficits and size of infarction between group EA1,EA2,EA4 and control group. Conclusion Pretreatment with single electroacupuncture stimulation for 30 min at Baihui acupoint can induce rapid and delayed tolerance to focal cerebral ischemia. Rapid tolerance develops 2 h after pretreatment while delayed tolerance develops 24 h after pretreatment.

Objective To evaluate the effective treatment for and prevention of complications. Methods The diagnosis and treatment of 32 patients with acute arterial ischemia of the lower extremity were analyzed (retrospectively). 4 cases were treated with thrombolytic therapy, 28 cases underwent emergency operation, of which 3 cases underwent amputation after embolectomy, and 25 cases were treated by arteriotomy of femoral artery and embolectomy with Fogarty catheter(7 cases underwent concomitant arterioplasty).Results One (patient) in the nonoperative group died; but there was no mortality in the operated group. Limb amputation was done in 3 cases, and limbs were saved in 28 cases. Conclusions For acute arterial ischemia of the lower (extremity), emergency arteriotomy of femoral artery plus embolectomy is the treatment of choice. This (therapeutic) approach can lower mortality and limb amputation rate.

OBJECTIVE: To discuss the influences of the concentrations of sodium cholate, cholesterol and drug, preparation temperature, ultrasonic time and power on the particle size and encapsulation efficiency of Flos Magnoliae volatile oil nano-liposome through film-ultrasonic wave technique together with membrane filter method. METHODS: The nano-liposomes were prepared by film-ultrasonic wave technique together with membrane filter method. The drug content in liposomes was determined by gas chromatography and the particle size was determined by laser light scattering granularity equipment. RESULTS: By film-ultrasonic wave technique together with membrane filter method, the liposomes in the range of 30-40 nm were prepared. The prepared nano-liposomes demonstrated good decentralization and homogeneity, and the encapsulation efficiency was (91.7+/-3)%. CONCLUSION: Film-ultrasonic wave together with membrane filter method is a simple method to fabricate nano-magnoliae liposome.

Objective To detect COX-2 mRNA in cervical cancer and normal cervix, and explore the pathogenesis of adenocarcinoma of the uterine cervix. Methods COX-2 expression was detected by RT-PCR to explore the relationship between COX-2 and the adenocarcinogenon of cervical cancer in 36 cases of adenocarcinoma of the uterine cervix and 15 cases normal cervical tissue. Results The positive rate of COX-2 mRNA in adenocarcinoma of the uterine cervix tissues (55.6%) was higher than that of normal tissues ( 20. 0% ), the difference was significant ( P ＜ 0. 05). The expression of COX-2 mRNA was associated with stages and clinical grading of tumor ( P ＜ 0. 05), but no significant difference was found between stages and clinical grading of uterine cervix adenocarcinoma( P ＞ 0. 05). Conclusion The hyper expression of COX-2 mRNA in uterine cervix adenocarcinoma took part in the carcinogenesis of tumor.

Objective To explore the effect of a training based on instructional video modeling designed from the mirror neuron theory on executive dysfunction after stroke. Methods 40 stroke inpatients with executive dysfunction from July, 2014 to July, 2015 were divided into control group (n=20) and observation group (n=20). The control group accepted executive rehabilitation training, while the observation group were asked to see the video of executive rehabilitation task before training. They were assessed with Behavioral Assessment of the Dysexecutive Syndrome (BADS) before and after intervention. Results The total score and scores of subtests except Rule Shift Cards and Key Search increased more in the observation group than in the control group (t>2.9, P<0.05). Conclusion Rehabilitation video as a visual stimulus for exercise training based on the mirror neuron theory could improve executive function recovery of stroke patients with executive dysfunction.

Objective To evaluate the effect of hypothermia on the pharmacokinetics of rocuronium in the pigs with hemorrhagic shock.Methods Thirty-two Bama mini pigs of both sexes,aged 4-6 months,weighing 22-25 kg,were randomly divided into 4 groups (n=8 each) using a random number table:normal temperature control group (group NC),normal temperature+hemorrhagic shock group (group NH),hypothermia control group (group HC),and hypothermia+hemorrhagic shock group (group HH).NC and NH groups were put in the normal temperature environment,and HC and HH groups were put in a freezer at-15 ℃.In NC and HC groups,rocuronium 3.78 mg/kg was injected via the auricular vein after the animals were awake.In NH and HH groups,hemorrhagic shock was then induced by removing 40％ of blood volume from the right femoral artery at a constant speed within 15 min (30 ml/kg),and rocuronium 3.78 mg/kg was injected via the auricular vein at 30 min after the model was successfully established.At 0 (T0),2 (T1),4 (T2),7 (T3),10 (T4),15 (T5),20 (T6),30 (T7),60 (T8),120 (T9),180 (T10),240 (T11) and 300 min (T12) after rocuronium injection,blood samples were collected from the internal jugular vein for determination of the blood concentration of rocuronium by high performance liquid chromatography-tandem mass spectrometry method.The maximum concentration (Cmax),elimination half-life (t1/2),plasma effect-site equilibration rate content (Ke0),area under concentration curve,and mean residence time (MRT) of rocuronium were calculated.Results Compared with group NC,the blood concentration of rocuronium was significantly decreased at T5-T12 in group NH,the blood concentration of rocuronium was significantly increased at T5-T12 in group HC,and t1/2 was significantly prolonged,Ke0 was decreased,and MRT was prolonged in NH and HC groups (P＜0.05 or 0.01).Compared with group HC,the blood concentration of rocuronium was significantly increased at T4-T12,t1/2 was prolonged,Ke0 was decreased,and MRT was prolonged in group HH (P＜0.05).Compared with group NH,the blood concentration of rocuronium was significantly increased at T5-T11,t1/2 was prolonged,Ke0 was decreased,and MRT was prolonged in group HH (P＜ 0.05).Conclusion Hypothermia can reduce the pharmacokinetics of rocuronium in the pigs with hemorrhagic shock.

MicroRNA are endogenous non-coding small RNA composed of approximately 18 - 23 nucleotides, mainly participating in post-transcription gene regulation.
