OBJECTIVETo improve the X-ray diagnosis of cervical spondylosis of vertebral artery type (VCS).

METHODSA blinded design research. The X-ray signs both 60 patients with VCS and 60 patients with cervical spondylotic radiculopathy were collected from January 2011 to November 2012. There were 36 males and 84 females, aged from 25 to 65 years old with an average of (48.4 ± 12.3) years old. Cervical curvature, atlanto-occipital joint angle, atlanto-axial joint angle, C2/C3 joint angle and lower cervical instability condition and segmental distribution were measured and recorded by X-rays. These data were analyzed and compared between the two groups after unblended. Combined with clinical manifestations,the X-ray imaging features of VCS were further analyzed.

RESULTSThere was significant difference in cervical curvature between two groups in anteflexion X-ray films (P < 0.05). There was significant difference in extension degree of atlanto-occipital joint angle between two groups (P < 0.01). There was significant difference in atlanto-axial joint angle between two groups in lateral X-ray films (P< 0.05). There was significant.difference in anteflexion degree of atlanto-axial joint angle between two groups (P < 0.05). There was no significant difference in C2/C3 joint angle between two groups. There was no significant difference in the lower cervical instability condition and segmental distribution between two groups. In VCS group, the mild and moderate dizziness was main symptom, flexion and extension activities of neck was most common cause in the dizziness; and always accompanied with headache; tenderness mostly concentrated in the upper cervical area.

CONCLUSIONBoth X-ray signs and clinical manifestations can prompt the abnormalities of the upper cervical structure or function in patients with VCS. Anteflexion activities of neck observed by functional position of X-ray films should be emphasized in diagnosis of VCS.

Objective To investigate the effect of Ulinastatin on the delivery of cytokines in patients with septic shock.Methods It was a prospective and controlled clinical study.Seventy-eight patients with septic shock were randomly divided into control group and treatment group and thirty-nine in every group.Patients in treatment group received Ulinastatin 200 000 units intravenous everyday for 3 days,while those in control group received equal volume of normal saline as placebo.At different time points (at 24 th,48 th,72 th hour after start of treatment),the levels of tumor necrosis factor-alpha (TNF-?),interleukin-1 (IL-1),interleukin-6 (IL-6 ),interleukin-8 (IL-8) and superoxide dismutase (SOD) in serum were assayed.Results In comparison with control group,the levels of TNF-?,IL-1,IL-6,IL- 8 of treatment group decreased markedly (P＜0.05,P＜0.01) at different time points,whereas the level of SOD was higher markedly (P＜0.05,P＜0.01) at various time points.Conclusion Ulinastatin has protective effect on patients with septic shock through decreasing the levels of TNF-?,IL-1,IL-6,IL-8 and increasing in the level of SOD.

The purpose of this study was to investigate how Zuogui pills from the Kidney-tonifying and Nourishing Yin formula, in combination with the gonadotrophin-releasing hormone antagonist cetrorelix, affected the ovarian local oxidative stress response in decreasing ovarian reserve (DOR) mice. All animal experiments were carried out in accordance with the guidelines and standards established by Jinan University's Experimental Animal Management Committee. Cyclophosphamide (CTX)-treated DOR mice were given Zuogui pills, cetrorelix, or a combination of the two drugs intragastrically. After treatment, there were changes in the estrous cycle, serum sex hormone levels, oxidative stress-related indexes, growth biochemical factor levels, and SIRT1/P53/P21 expression. In comparison to the model group, the Zuogui pills and the cetrorelix+Zuogui pills group had significantly prolonged estrous periods and shortened interestrous periods, and the cetrorelix+Zuogui pills group had a significantly shortened cycle length. Follicle-stimulating hormone (FSH) decreased and estradiol (E₂) increased in all treatment groups compared to the model group, oxidative stress indexes nitric oxide synthase (NOS), nitric oxide (NO), and reactive oxygen species (ROS) decreased, growth biochemical factors brain derived neurotrophic factor (BDNF) and growth differentiation factor 9 (GDF-9) concentrations increased significantly, and leukemia inhibitory factor (LIF) showed no significant change. SIRT1/P53/P21 immunohistochemical results revealed that, when compared to the model group, the expression of SIRT1 increased while the expression of P53 and P21 proteins decreased in all treatment groups, with the cetrorelix+Zuogui pills group having the largest decrease, with significant differences in all indicators. We conclude that cetrorelix combined with Zuogui pills for kidney nourishing and Yin recipe improved the oxidative stress response in the follicle by regulating the SIRT1/P53/P21 pathway, reducing peroxide product production, protecting ovarian function, and regulating ovarian hormone secretion, and its efficacy is superior to that of cetrorelix or Zuogui pills alone.

OBJECTIVE: To explore the change of brain cognition function in severe head injury and the correlation between P300 in event-related potential (ERP) and intelligence quotient (IQ). METHODS: Auditory P300 was measured and intelligence quotient was tested by Wechsler Adult Intelligence Scale Revised in China (WAIS-RC) in 40 severe head injury patients. Auditory P300 was measured in 40 normal healthy people as control group. RESULTS: The latencies of P300 in severe head injury patients group were longer than in control group. There was a significant difference between the two groups (P< 0.01). There were significant negative correlations between P300 latency and VIQ and FIQ respectively (r=-0.335,-0.344, P<0.05). CONCLUSION ERP might be taken as an objective index for measuring the change of the brain cognition function in patients with severe head injury.

Sixty healthy Sprague-Dawley male rats were used and divided randomly into control group (group C), cadmium loading group with medium dose (group M) and cadmium loading group with high dose (group H). Groups C, M and H were orally dosed daily with 0, 5 and 10 mg/kg of cadmium for over 6 weeks. Effects of cadmium loading on testis and endocrine function of reproduction in male rats were studied. The results showed that the zinc content decreased slightly in testis and plasma, and the cadmium concentration increased significantly in the testis of groups M and H; while the plasma levels of cadmium and zinc had no obvious difference as compared with those of group C; daily sperm production in the testis of group H decreased markedly during week 3 of cadmium loading, and was significantly lower in groups M and H as compared to that in group C during week 6; alkaline phosphatase (ALP) in group H and lactate dehydrogenase-X (LDH-X) in groups M and H were markedly lower compared to those of group C; plasma testosterone (T) level in both cadmium loading groups decreased and was low or significantly lower than that in group C; follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels had no apparent difference between the three groups. It is suggested that the gradual accumulation of cadmium in testis tissue induced by chronic cadmium loading results in changes in some enzyme activity, a decrease in sperm production, and defect of endocrine function activity in the testis.
