Objective To study the effects of hypothermia therapy on inflammation level and safety of patients with severe nervous injury.Methods A total of 82 patients with severe nerve injury were divided into study group and control group by random digits table, 41 patients in each group.The patients in these two groups had no statistical dis-parities in inflammatory agent and intracranial pressure (p>0.05).The patients in the control group were treated by routine therapy and those in the study group were treated by cephalic hypothermia therapy additionally.The two groups were compared in terms of the level of TNFα, IL-6 and IL-8 in the cerebrospinal fluid, prognosis and safety.Re-sults Before treatment there was no significant difference in inflammation level between the two groups (p>0.05). After treatment, the TNFα, IL-6 and IL-8 levels in the study group were significantly lower than those in control group (p<0.01).Before treatment there was no significant difference in ICP between two groups (p>0.05).How-ever, after treatment there was a significant difference in ICP between the two groups in all time points (p<0.01). The GOS score in the study group was significantly lower than that in the control group.There was no statistical dis-parities in complications between the two groups (p>0.0).Conclusion The hypothermia therapy has a great clini-cal efficacy and safety on severe never injury patients, which makes it worth clinical application.

The degranulation of mast cells represents a pivotal e-vent in the allergic disorders.The Src family kinases(SFKs)are as a starting signal in the activation of mast cell.Lyn,Fyn and Syk play important regulatory role in the degranulation of mast cells.Regulating SFKs can reduce the degranlation process and inhibit the allergic disorders.Therefore,SFKs inhibitors can be potential drugs in the allergy.It is necessary to study the targeted medicine of SFKs,which will be a new direction of drug develop-ment.

Objective To investigate the effects of antidepressant therapy on whole regulating function of OPG/RANKL/RANK system in ovariectomized (OVX) rat model with depressive disorder.Methods Forty sexually mature female SD rats were used as subjects.The rats were randomly divided into 8 groups as following:sham group(Sn),depression group(Dn),the OVX group (On),the OVX with depression group(ODn),OVX with depression +sertraline group (ODs),and OVX with depression + citalopram (ODx),OVX with depression + reboxetine group(ODr),OVX with depression + venlafaxine group (ODw).Bilateral oophorectomy was applied to establish the ovariectomized rats model.Chronic unpredictable mild stress(CUMS) was used to estalish depression model.Open-field test and sugar consumption experiment were applied before the experiment and the 28th day of the experiment.Immunohistochemistry and Quantitative Real-time PCR were used to observe the expression of OPG,RANKL and RANK.Results After chronic unpredictable mild stress the scores of horizontal motion,vertical motion and percentage of sugar consumption experiment in Dn group were decreased contrast to the in control Sn group (P＜0.05)and the scores in ODn group were decreased in contrast to the On group (P＜0.05).The protein and gene expression of RANK in Dn group and On group were increased in contrast to the Sn group (P＜0.05).The protein and gene expression of RANKL in Dn group and On group were increased in contrast to the Sn group (P＜0.05).The gene expression of OPG in ODs group(5.94±0.79),ODw group(5.99± 1.08) and ODr group(6.59±0.69) was decreased in contrast to the ODn group (4.96±0.51) (P＜0.05).The gene expression of RANK in ODs group (2.82±0.23),ODx group(3.03±0.04) was increased in contrast to the ODn group(3.44±0.18) (P＜0.05).The gene expression of RANKL in ODs group(4.82±0.94),ODx group(5.00±0.82) and ODw group(5.23±0.88)was decreased in contrast to the ODn group (3.69± 0.69) (P＜0.05).Conclusion The expression of RANK and RANKL in femoral neck is increased both in depressive disorder model rats and ovariectomized model rats.The antidepressant can up-regulate the expression of RANK,and down-regulate the expression of OPG and RANKL in the OVX with depression group.Of the effect,sertraline is the strongest,however reboxetine mesylate is the poorest.

Objective To study the protection effect of acupuncture at acupoint ST 36 in rat with cold-restrainted stress-induced ulcer,and to observe the expression of NOS in hypothalamus and adrenal. Methods Ulcer Index in rats was used to study the protection effect of acupuncture, and and RT-PCR was employed to study the expression of NOS in hypothalamus and adrenal. Images were analyzed with semi-quantitative method. Results The ulcer Index was significantly decreased in rats with stress-induced ulcer by acupuncture as indicated by a comparison with those without acupuncture. The expression of NOS1 in hypothalamus was increased by acupuncture protect stress-induced ulcer. The increased expression of NOS2 was involved in stress-induced ulcer, and acupuncture decreased its expression. The expression of NOS3 in hypothalamus had the similar reaction to NOS2, but the decreased effect of acupuncture was limited. The expression of NOS1 and NOS3 in adrenal were increased by cold stress, only the expression of NOS1 could be repressed with acupuncture. There was no NOS2 expression in adrenal in stress-induced ulcer rats. Conclusion The protection effect in stress-induced ulcer exerted by acupuncture at acupoint ST 36 were mediated by increase of the physiological expression of NOS1 in hypothalamus as well as decrease of the expression of NOS2,NOS3 in hypothalamus and repress of the expression of NOS1 in adsenal.

Objective To investigate the effect of soybean isoflavone on histology and uhrastructure of benign prostatic hyperplasia in rats.Methods Male SD rats were injected subcutaneously testosterone propionate for 28 d to induce prostatic hyperplasia,and the rats were divided into 5 groups:control group,model group,and 3 test groups with SI in a dose of 60 mg/(kg·d),120 mg/(kg·d) and 240 mg/(kg·d),respectively.The wet prostate weight,prostatic index,morphological,uhrastmetural and morphometrie changes of the prostatic shndular and interstitial tissues were observed.Results The prostate wet weight,prostatic index and prostatic volumes in all dose groups were significantly lower than those in the models.In comparison with the model group,height of prostatic epithelial cells,glandular average diameters,volumes and surface areas in unit volume,as well as glandular circumferences,glandular relative total volumes and interstitial relative total volumes were all significantly decreased.Glandular counts,density,ratio of glandular surface area to volume,and glandular average curvature were all increased.Conclusions Soybean isoflavone can inhibit prostatic hyperplasia in rats.

ObjectiveTo study the special effect of oxytocin and vasopressin mRNA expression by acupuncturing acupoint ST36.Methods78 SD male rats were divided into four groups, acupuncturing ST36 group, acupuncturing para-acupoint ST36 group, bondage group and control group. RT-PCR was used to observe the oxytocin and vasopressin mRNA expression in 2,4,6,8 hours after acupuncture, semi-quantitative result was obtained by using image analysis system.ResultsOxytocin mRNA expression in hypothalamus in 2,4 hours was the statistically significant different in acupuncturing para-acupoint ST36 group contrast with other three groups, while there was not statistically different between all groups on oxytocin mRNA expression in 6,8 hours. Vasopressin mRNA expression in hypothalamus in 2,4,6,8 hours was statistically depressed in acupuncturing acupoint ST36 contrast with other three groups.ConclusionOxytocin mRNA expression in hypothalamus increases for short time after acupuncturing para-acupoint ST36. Vasopressin mRNA expression in hypothalamus decreases for long time after acupuncturing acupoint ST36.

ObjectiveTo investigate effects of electroacupuncture(EA) of Zusanli(ST36) on changes of substance P(SP) mRNA expression in rat brain stem.Methods78 SD rats were evenly randomized into Zuanli-EA group, non-acupoint group, bondage groups(at the end of 2h,4h,6h,8h after 30 minute EA stimulation in each group) and control group. RT-PCR and image processing were used to study the change of SP mRNA level in brain stem.ResultsIn control groups,there was SP expression. An increase of SP mRNA expression was seen in Zusanli group and non-acupoint group comparing with control group at the end of 2h after 30min EA stimulation(P<0.05).There was difference between above two groups at the end of 6h and 8h(P<0.05).ConclusionEA stimulation elicited an accelerated expression of SP gene. Zusanli-EA stimulation can increased this expression, which may constitute one of the mechanisms for gastrointestinal motility and eletroacupuncture analgesia.

Atherosclerosis is a complex metabolic cardiovascular disease. such inflammatory phenomena as the invasion of lipid into the arterial intima and accumulation, the increase of foam cells, the exacerbation of inflammatory lesions, plaque necrosis and disintegration, ulcer bleeding and thrombosis, fibrosis and calcification, etc, are basic pathological characteristics of ather-osclerosis. In this process, macrophages and T lymphocytes play an important role. In recent years,atherosclerosis pathology re-search mainly focuses on the role of macrophage polarization.
Basically,macrophage can be divided into two subtypes: classi-cal activation macrophage M1 and alternative activation macro-phage M2. Therefore to paper reviews the meaning of M1 and M2 macrophage polarization during atherosclerosis, regulatory pathways and drug targets research status to provide new direc-tion for innovative drugs and disease treatment.

OBJECTIVETo analyze the clinical characteristics, diagnosis and treatment of pseudohypoparathyroidism (PHP).

METHODSThe clinical data of 15 patients with pseudohypoparathyroidism (including 9 male and 6 female patients) admitted in our hospital between January, 1990 and July, 2011 were reviewed.

RESULTSThe disease course of the patients ranged from 3 days to 21 years, and such symptoms of tetany and fatigue were found in all the patients. Most of the patients had a history of seizures. Laboratory tests suggested commonly low serum calcium, hyperphosphatemia, and parathyroid hormone (PTH) elevation. Head CT indicated multiple intracranial calcifications in 9 cases, and abnormal thyroid function was found in 4 cases. No specific treatment was available for this disease, and life-long calcium and vitamin D supplementation was advised to prevent acute attacks and disease progression.

CONCLUSIONPHP is a rare genetic disease with a high rate of misdiagnosis in initial diagnosis. For repeated tetany and epileptic attacks and children with congenital developmental defects, examinations of blood calcium, phosphorus, and PTH and brain CT should be ordered as soon as possible. Long-term calcium and vitamin D supplementation is suggested for the treatment, and the presence of concomitant thyroid dysfunction or hypogonadism necessitates corresponding treatments.
