Objective To st ud y the characteristics of clinical manifestations and laboratory findings in pati ents with adrenocorticotropin-independent macronodular adrenal hyperplasia (AIM AH). Methods The clinical and laboratory findin gs of 4 patients with AIMAH were described and analyzed. Results All the 4 patients had clinical features and biochemical evide nce of Cushing′s syndrome. Plasma ACTH level was undetectable in all 4 patients . Serum cortisol secretion rhythm was abnormal. Low-and high-dose dexamethason e suppression tests failed to suppress cortisol secretion. CT examination showed bilateral macronodular adrenal enlargement. Conclusion AIMAH is recognized as a rare subtype of Cushing′s syndrome with uniqu e clinical and pathological findings.

OBJECTIVE:To provide reference for clinical rational drug use.METHODS:The content of Levocarnitine Injection from two manufactories in 3 different dissolvants(5%Glucose,0.9%Sodium Chloride Injection,and Fructose Injection) within 6 h was determined by HPLC.The change of microparticle was measured by light blockage method in accordance with China Pharmacopeia(2005 edition),and the appearance and pH of the mixtures were observed as well.RESULTS: The changes in appearance,turbidance,pH value,content and microparticle were not significant.CONCLUSION: Levocarnitine Injections from two manufactories were stable within 6 h after mixing with 3 different dissolvants(5%Glucose, 0.9%Sodium Chloride Injection,and Fructose Injection).

Objective To evaluate the ischemic postconditioning on endoplasmic reticulum stress during cerebral ischemia/reperfusion (I/R) in rats.Methods Ninety adult male Sprague-Dawley rats,aged 350-450 g,were randomly divided into 3 groups (n =30 each) using a random number table:sham operation group (S group),I/R group,and ischemic postconditioning group (group P).Focal cerebral I/R was induced by electrocoagulation of left middle cerebral artery and 30 min occlusion of bilateral common carotid arteries followed by reperfusion.In group P,bilateral common carotid arteries were subjected to 3 cycles of 30 s reperfusion and 10 s ischemia at the beginning of reperfusion.At 24 h of reperfusion,neurological deficit was scored,and cerebral infarct size was detected by TTC staining.At 6,12 and 24 h of reperfusion,the expression of glucose-regulated protein 78 (GRP78),C/EBP homologous protein (CHOP) and caspase-12 in the ischemic area were measured (using immunohistochemistry).The neuronal apoptosis in the ischemic area was detected by TUNEL.Results Compared with S group,the neurological deficit score was significantly increased,cerebral infarct size was enlarged,the neuronal apoptosis was increased,and the expression of GRP78,CHOP and caspase-12 was up-regulated in I/R and P groups.The neurological deficit score was significantly lower,cerebral infarct size was smaller,the expression of GRP78 was higher at 12 and 24 h of reperfusion,the neuronal apoptosis was lower at 24 h of reperfusion,and the expression of CHOP and caspase-12 was lower in group P than in group I/R.Concluion Ischemic postconditioning can inhibit neuronal apoptosis mediated by endoplasmic reticulum stress during cerebral I/R,which dose not play a leading role in cerebral protection in rats.

Objective To explore the mediating effect of self-efficacy in family environment and mental health.Methods Using family environment scale (FES),general self-efficacy scale (GSES)and mental health scale (MHT)to investigate 360 junior high school students in a middle school by cluster random sampling.Results (1)There was a negative correlation between the family environment intimacy(6.60 ±2.12) and total score of knowledge (3.98±l.85)and mental health(44.56±12.93)(r=-0.170,P＜0.01;r =-0.116,P＜0.05),and a positively correlation on contradictions between the family environment(3.55±2.21) and mental health (44.56± 12.93) (r=0.183,P＜0.05).There was a positively correlation among family environment intimacy(6.60±2.12),the knowledge(3.98± 1.85) and general self-efficacy(2.51 ±0.50) (r =0.148,P＜0.05;r=0.222,P＜0.05).There was a negative correlation between general self-efficacy(2.51± 0.50) and mental health (44.56± 12.93) (r=-0.275,P＜0.05).(2)In the relationship between intimacy and mental health in the family environment,the general self efficacy played partial of intermediary effect,and the mediating effect was 30.83％.In the relationship between family environment and mental health,general self efficacy played intermediary effect.Conclusion The general self efficacy plays an intermediary role in the relationship between family environment intimacy and knowledge and mental health.

OBJECTIVE: To investigate the influence of signal transducer and activator of transcription 3 (Stat3) and hypoxia-inducible factor-lα (HIF-1α) on the resistance effect of laryngeal squamous cell carcinoma to radiation therapy and chemotherapy under the hypoxia circumstances. METHOD: Western blot was used to test the expression of p-Stat3 and HIF-1α in the Hep-2 cells under the hypoxia conditions. MTT assay was used to test the proliferation of Hep-2 cells after radiation therapy and chemotherapy; the Hep-2 cells were suppressed expression of Stat3 and/or HIF-1α. RESULT: (1) AG490 induced significant proliferation inhibition on Hep-2 cells and Hep-2HIF-1α-/- cells in vitro underthe hypoxia environments (P < 0.05); (2) Suppressing expression of Stat3 reduced the expression of HIF-1α protein (P < 0.05); (3) Combined inhibition of Stat3 and HIF-1α enhanced radio- and chemo-sensitivity in laryngeal squamous carcinoma cells under hypoxia. CONCLUSION Combined inhibition of Stat3 and HIF-1α can further enhance radio- and chemo-sensitivity in laryngeal squamous carcinoma cells under hypixia compare than inhibiting Stat3 or HIF-1α alone. Effectively blocking of HIF-1α pathway and suppressing the expression of Stat3, would be an effective method to enhance radio- and chemo-sensitivity in laryngeal squamous carcinoma cells, which provides a new thought to reduce the resistance to treatment.

Objective To study the anti-fatigue function of black currant extracts in mice. Method Kunming mice (SPF) were randomly divided into black currant extracts high, middle, low dose group, black currant natural juice dose group and control group according to their body weights. Mice were administered ig daily for 30 d. The loaded-swimming time ,hepatic glycogen ,blood urea nitrogen were measured. Results Black currant extracts high, middle, low dose groups could increase the time of loading swimming,and the hepatic glycogen content,and decrease blood urea nitrogen in mice. All indices above were more than those in black currant natural juice except the blood urea nitrogen content was lower. Conclusion Black currant extracts could alleviate physical fatigue in mice, and be better than black currant natural juice.

Abtract: Acute coronary syndrome is a common clinical and frequently occurring disease, belonging to the chest discomfort, heartache, and true heart pain of TCM category. The clinical observation shows that the heat and blood stasis, and poison damage heart nutrient is one of the important mechanisms of triggering coronary syndrome. Therefore, the method of promoting blood circulation to remove meridian obstruction and the Qing Ying detoxication was established as the basic treatment, and Danshen Tongluo Jiedu Decoction is applied as the main formula. According to the different types of disease and syndrome differentiation, flexible modification can achieve good efficacy. It is expected that these will provide new ideas and methods for clinical treatment of acute coronary syndrome.

Objective To improve the recognition of treatment of adult T lymphoblastic lymphoma (TLL) with Hyper-CVAD regime.Methods The turnovers of 7 cases treated with Hyper-CVAD regime were summarized.Results Among the 7 cases,1 case died after the first unfinished chemotherapy,1 case gained complete remission before autologous stem cell transplantation but relapsed after transplantation,3 cases gained complete remission until now,2 cases without transplantation relapsed and then gave up following treatments after treating with ICE regime or the virgin regime,but the therapeutic effects were poor.Conclusions Adult TLL should get early chemotherapy treatments,and some special characteristics should be noted,the treatment does not relate to the stage,the chemotherapy treatment should be carried out regularly and enough,radiation of mediastinum mass can be applied after 4 cycles of Hyper-CVAD regime,choose suitable transplantation method.
