Objective: To study the relation among inducible nitric oxide synthase(iNOS), endothelial nitric oxide synthase(eNOS) and vascular endothelial growth factor (VEGF)in oral squamous cell carcinoma(OSCC) and their relation to clinical pathology and angiogenesis.Methods:OSCC tissue specimens were surgically obtained from 64 patients,the expression of iNOS,eNOS and VEGF in the samples were studied by immunohistochemistry technique. Microvessel density(MVD) was measured by counting the endothelial cells stained with anti-FⅧRAg antibody. Results: ①Positive VEGF and iNOS and eNOS immunostaining was detected in 39(60.94%),42(65.63%)and 45( 70.31%)of the cases respectively.②Expression of VEGF was significantly related to that of iNOS(P05).③MVD in OSCC tissue was positively correlated with the expression of VEGF and iNOS(P05).④VEGF expression was positively correlated to the pathological grade of OSCC(P0.05).Conclusion:iNOS,rather than eNOS, plays a positive role in OSCC development.iNOS and VEGF have a positive correlation in angiogenesis of OSCC.

This study examined the analgesic effect of diprospan in rats with trigeminal neuralgia. Rat model of trigeminal neuralgic pain was established by loosely ligating the left infraorbital branch of the trigeminal nerve. After allodynia developed, the rats were randomly divided into 2 groups (n=20 in each): diprospan group, in which the rats received diprospan (7 mg/mL, 0.1 mL) injected to the left infraorbital foramen area; control group, in which saline (0.1 mL) was administered as the same manner as the diprospan group. The pain threshold (PT) in the left infraorbital area was measured before and 2, 6, and 8 weeks after the administration. The expression of neuropeptides [substance P, preprotachykinin A (PPTA), calcitonin gene-related peptide (CGRP)] in the trigeminal nerve was detected at the same time points as the PT measurement by immunohistochemistry or in situ hybridization method. The results showed that in the diprospan group, the PT was 10.65±1.26, 10.77±1.19 and 14.13±1.34 g 2, 6, and 8 weeks after the administration respectively, significantly higher than that before the administration (PT value: 0.36±0.11) (P<0.05 for each). In the saline group, the PT was 0.37±0.13, 0.66±0.09, 4.45±1.29 and 13.72±1.72 g before and 2, 6, and 8 weeks after the administration respectively with differences being significant between before and 6, 8 weeks after the administration (P<0.01). No significant difference existed in the PT between the diprospan group and the saline group at pre-administration (P>0.05). The PT in the diprospan group was significantly greater than that in the saline group 2 and 6 weeks post-administration (P<0.05). In the diprospan group, the expression levels of neuropeptides were significantly reduced as compared with those in the saline group 2 and 6 weeks post-administration (P<0.05). It was concluded that diprospan has an obvious analgesic effect on the trigeminal neuropathic pain partly by reducing the expression of neuropeptides in the trigeminal ganglia.

Objective To observe the tumorigenicity of High Five insect cell line in Balb/c nude mice,and make sure the safety of the cells when used in vaccine production.Methods Balb/c nude mice were randomly divided into 5 groups:the basic cell bank of High Five group,the highest limited passages of High Five group,HEp-2 cell group as positive control,CEF cell group as negative control,and blank control.Except of the blank control,cell suspension was injected subcutaneously into the nude mice in the different groups,respectively.At 3 and 12 weeks after injection,anatomical observation and histopathologic examination were performed to detect the tumor formation.Results At 3 and 12 weeks after injection,the tumorigenicity study results showed that no tumor developed at the transplantation site in the blank control group,negative group,and High Five groups.Histopathological examinations also showed no abnormality in these groups.Otherwise,squamous cell carcinoma was developed in the positive group at 3 weeks after injection.Conclusions High Five cells of basic cell bank and highest limited passages are not tumorigenic,and can be used in vaccine production safely.

Objective To study the risk prediction for new intracerebral hemorrhage (ICH) with high sensitivity C-reactive protein ( hs-CRP) level. Methods In a retrospective, nested, case-controlled study, 323 cases of ICH were identified and matched with 646 controls. The hs-CRP levels at baseline were compared between the two groups. The relevance of different hs-CRP levels and the risk of ICH were analyzed. Results The ICH group had a higher median hs-CRP levels (1.10 mg/L) as compared with the control group (0. 66 mg/L) with significant difference ( P<0.01 ). In addition, the increase of risk associated with hs-CRP levels was primarily observed in the individuals with the highest quartile of hs-CRP levels(>2.12 mg/L). These patients had an increased risk of ICH (OR 2. 58, 95% CI 1. 77 to 3. 76) as compared with those in the lowest quartile(≤=0.30 mg/L). Individuals with basiline hs-CRP levels above the specified cut point of 3 mg/L ormore and those in the 80th percentile were at a markedly increased risk of ICH (for specified cut point of 3 mg/L,0R2.26, 95% CI 1.60-3.20, P<0.01; for 80th percentile, OR 2.24,95% CI 1.60-3.13, P <0.01, respectively). Conclusions Risk of ICH might be predicted with the level of hs-CRP. With the increase of hs-CRP level at baseline, the risk of ICH was increased.

Objective To observe the distribution and influence factors of serum high sensitivity C-reactive protein (hs-CRP) in general population. Methods In a cross-sectional population survey, a total of 101 510 subjects who were employed by Kailuan Group had been carried out a healthy examination in the period of 2006 to 2007. In the statistical analysis, we observed 91 123 subjects (males 72 805, females 18 318) who had full information and met the inclusion criteria of the study. Results ( 1 ) The geometric means of hs-CRP were 0. 70 mg/L, 0. 70 mg/L and 0. 73 mg/L in all subjects, males and females,respectively, the 95th percentiles were 6.28 mg/L, 6.20 mg/L and 6.49 mg/L, respectively. The concentrations of hs-CRP increased with age in both males and females (P trend = 0. 001 ). Serum hs-CRP geometric mean was 0. 54 mg/L and the 95th percentile was 5.40 mg/L in health group, while the geometric mean was 0. 80 mg/L and the 95th percentile was 6. 57 mg/L in non-health group. (2) Multiple linear regression analysis showed that concentrations of hs-CRP were positively associated with gender, age,systolic blood pressure, body mass index, total cholesterol, triglycerides, fasting blood glucose, smoking history, history of coronary heart disease and stroke history, but concentrations of hs-CRP were inversely related with diastolic blood pressure, high-density lipoprotein cholesterol and alcohol history. Conclusion Serum concentrations of hs-CRP level increased with age, concentrations of hs-CRP were higher in females than males; a variety of cardiovascular factors effected the concentrations of hs-CRP.

Objective: To investigate the impact of improved AHA cardiovascular health behavior score (CHS) on short-time systemic blood pressure variability (SBPV) in elder population.
Methods: A total of 2464 participants ≥ 60 years from 3 hospitals of Kailuan area were taken for cohort study. The participants had no cardiovascular disease, not taking anti-psychotic drug, Parkinson treatment drug, anti-depression drug and analgesic drug within 2 weeks. All participants received 24-hour ambulatory blood pressure monitoring (ABPM) and the 24-hour, day-time, night-time SBPV were deifned by the standard deviation of 24-hour, day-time, night-time systolic blood pressure. The influence of CHS on SBPV was studied by multi-linear regression analysis. Improved cardiovascular health behavior and factors implied as changing the vegetable intake amount to salt amount by American Humane Association, 2010; boundary of BMI based on《Guidelines for prevention of overweight and obesity in Chinese adults》; status of exercise was deifed as the ideal status: ≥80 min/week, general status: < 80 min/week and bad status: no exercise.
Results: Finally, 1812 participants were recruited for survey and they were divided into 3 groups according to improved CHS: Group①, CHS (0-4) points,n=56, Group②, CHS (5-9) pointsn=1600 and Group③, CHS (10-14) points,n=156. The 24-hour SBPV in Groups①,②and③were 16.02 mmHg, 14.91 mmHg and 13.18 mmHg; day-time SBPV were 15.42 mmHg, 14.50 mmHg and 13.22 mmHg; night-time SBPV were 12.68 mmHg, 11.44 mmHg and 10.16 mmHg, allP<0.05. Multi-linear regression analysis indicated that with adjusted confounding factors, with 1 point of CHS elevation, the 24 hour-, day-time, night-time SBPV would reduce for 0.20 mmHg, 0.19 mmHg and 0.37 mmHg respectively, allP<0.05.
Conclusion: CHS was negatively related to short-time SBPV in elder population.

Primary angle-closure glaucoma(PACG)is a common cause of blindness, and angle closure is a fundamental pathologic process in PACG. With the development of ophthalmic equipment, the pathogenesis of PACG has been better understood. In addition to the traditional mechanisms of pupillary block and plateau iris, it has been found that its pathogenesis is not only related to abnormal ocular anatomy, but also more closely related to ocular dynamics, genetic factors, and psychophysiologic stressors. This article summarizes the pathogenesis and risk factors of PACG in conjunction with literature reports, with a view to providing guidance for clinical work and useful theoretical support for early diagnosis and treatment options for glaucoma.

Objective:To explore the function of temperature difference stimulation oral nursing for the patients with mild to moderate dysphagia after oral cancer operation.Methods:A total of 64 patients with mild to moderate dysphagia after oral cancer surgery admitted to our hospital from January 2019 to June 2021 were selected as the research subjects by convenient sampling method, and divided into control group ( n=32) and observation group ( n=32) according to random number table method. The grouping method was random number table method. The control group was treated with traditional ice-water stimulation rehabilitation training, and the observation group was treated with temperature difference stimulation oral care. The degree of dysphagia, nutritional status, postoperative complications and quality of life were analyzed and compared between the two groups. Results:After the intervention, the degree of dysphagia in the observation group (water swallow test) fromⅠto Ⅳ degree were 2, 11, 13 and 6 cases, while in the control group were 9, 17, 4 and 2 cases, the difference was significant ( Z=-3.41, P<0.05). After the intervention, the serum albumin of the observation group was (38.74 ± 4.87) g/L, which was significantly higher than that of the control group (35.81 ± 5.14) g/L. there was significant difference between the two groups ( t=2.34, P<0.05). After the intervention, the self scores of chewing, swallowing, anxiety, emotion and quality of life in the Chinese version of the University of Washington quality of life scale in the observation group were 70.28 ± 10.39, 68.20 ± 9.43, 72.39 ± 12.28, 65.30 ± 15.33 and 78.05 ± 9.47, which were significantly higher than those in the control group 64.29 ± 9.26, 61.42 ± 12.38, 64.50 ± 10.43, 58.08 ± 11.62 and 72.92 ± 10.40, The difference was statistically significant ( t values were 2.06-2.77, all P<0.05). Conclusions:Oral nursing with temperature difference stimulation can effectively improve the swallowing disorder of patients after oral cancer surgery, reduce the incidence of aspiration and malnutrition, and improve the quality of life of patients.
