Background The ocular nerve of trigeminus is the sensation and nutrition nerve of cornea.Whether trigeminal neuralgia affect the function of ocular surface and the morphology of corneal nerve plexus or not is below understanding.Confocal microscope is a non-invasive method for in vivo corneal examination.Objective This study was to analyze the ocular surface findings and observe the morphology and density of corneal nerve under the confocal microscopy in patients with trigeminal neuralgia.Methods Thirty-three eyes of 33 patients with trigeminal neuralgia were collected from the Department of Pain Management in Henan Provincial People's Hospital.The corneal perceptual sensitivity was examined using corneal aesthesiometer,and the function of lacrimal secretion (Schiemer Ⅰtest),tear break-up time (BUT) were performed to evaluate the influence of trigeminal neuralgia on ocular surface.The change of corneal nerve was observed under the confocal microscopy.The fellow eyes served as controls.The informed consent was obtained from the subjects before any examination.Results The fiber length of corneal perceptual sensitivity was (54.348±6.793)mm and (55.217±6.480)mm in trigeminal neuralgia group and control group without a significant difference between them (t=0.641,P=0.528).No significant differences were found in the mean value of Schiemer Ⅰtest (9.390±6.583mm vs 9.300±5.295mm) and BUT result (6.09±4.177s vs 6.13±4.799s) between trigeminal neuralgia and control group(t=0.070,P=0.945;t=-0.085,P=0.933).The densities value of corneal subepithelial nerve plexus at the nasal,temporal,superior,inferior and central area was insignificantly changed between trigeminal neuralgia group and control group(P=0.840,0.459,0.268,0.120,0.607).Tenuous,bending and circling nerve fibers were seen in corneal stroma under the confocal microscope,while the nerve fibers were strict in controls.Conclusion Trigeminal neuralgia does not dramatically affect eye surface function and corneal subbasal nerve plexus density,but corneal nerve fibers with trigeminal neuralgia are more bending than normal people.

OBJECTIVETo observe the effect of American Ginseng Capsule (AGC) on the liver oxidative injury and the Nrf2 protein expression in the liver tissue of rats exposed by 900 MHz cell phone electromagnetic radiation.

METHODSTotally 40 male SD rats were randomly divided into the normal control group, the model group, the Shuifei Jibin Capsule (SJC) group, and the AGC group,10 in each group. Rats in the normal control group were not irradiated. Rats in the rest three groups were exposed by imitated 900 MHz cellular phone for 4 h in 12 consecutive days. Meanwhile, rats in the SJC group and the AGC group were intragastrically administrated with suspension of SJC and AGC (1 mL/200 g body weight) respectively. Normal saline was administered to rats in the normal control group and the model group. The histolomorphological changes of the liver tissue were observed by HE staining. Contents of malonic dialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase (GSH-PX)were detected by colorimetry. The Nrf2 protein expression of hepatocytes was detected by immunohistochemical assay and Western blot.

RESULTSCompared with the normal control group, hepatocyte nucleus was atrophied or partially disappeared, the contents of liver MDA and Nrf2 protein obviously increased (P <0. 05, P <0. 01); contents of liver SOD and GSH decreased (P <0. 05) in the model group. Compared with the model group, karyopyknosis was obviously attenuated and approached to the normal level in the SJC group and the AGC group. The contents of liver MDA and Nrf2 protein expression decreased (P <0. 05), and the contents of liver SOD, GSH, and GSH-PX obviously increased (P < 0.05) in the SJC group. The contents of liver MDA and the Nrf2 protein expression decreased (P < 0.05), and contents of SOD and GSH obviously increased in the AGC group (P <0.01, P <0.05).

CONCLUSIONSThe electromagnetic radiation induced by 900 MHz cell phone could affect the expression of Nrf2 protein, induce oxidative injury, and induce abnormal morphology of liver cells. SJC and AGC could promote the morphological recovery of the liver cells. Its mechanism might be related to affecting the expression of Nrf2 protein and attenuating oxidative damage of liver cells.

Objectives To investigate the characteristics of changes in serum metabolic profile before and after resection of carcinoma tissues to establish a disease distinguishing model,to analyze the changing trend of characteristic metabolites,and to determine the molecular mechanism and potential clinical value of characteristic metabolic markers for HBV-related liver cancer.Methods Ultraperformance liquid chromatography-mass spectrometry (UPLC-MS) was used to analyze the serum metabolites of 15 patients with hepatocellular carcinoma (HCC) before and after partial hepatectomy and on 25 healthy volunteers.The pattern recognition method and nonparametric test analyzes were used to analyze the data and to identify the specific metabolites and their changes after resection of carcinoma tissues.Results We established the principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) disease distinguishing model for HCC patients before and after operation as against the healthy volunteers.To distinguish between the liver cancer group and the normal control group,27 characteristic metabolites were selected from the patients before and after resection of carcinoma tissues.Eight moved towards the normal control after resection of carcinoma tissues.This indicated that liver carcinoma was an important impacting factor for these metabolites.Finally,7 metabolites were identified,and these metabolites had high diagnostic value as shown on ROC curves.Conclusions Through serum metabolic profiling of patients before and after resection of carcinoma tissues,a high correlation between metabolism and hepatocellular carcinoma was found.Researches on endogenous metabolites and pathways in liver diseases will provide a better understanding of the molecular mechanisms and provide further directions for clinical diagnosis and treatment.

Objective: To control the quality of Fici Hirtae Radix by establishing quality standards. Methods: The origin mistakes of Fici Hirtae Radix in Chinese Pharmacopoeia (1977 edition) were modified by searching and mining plant morphology characters, distribution of origin, historical evolution, clinical efficacy and modern research, medicinal standards in different regions on Ficus hirta Vahl and Ficus simplicissima. Morphological identification, microscopical characteristics based on transverse section and powder, and thin layer chromatography were adopted to identify commercial medicinal materials of Fici Hirtae Radix from different sources. The content of psoralen and bergapten was determined by HPLC. Moisture content, total ash, acid-insoluble ash, and ethanol-soluble extractives were determined by methods described in appendices of Chinese Pharmacopoeia (2010 edition). Results: The origin of Fici Hirtae Radix was not F. simplicissima Lour., but F. hirta Vahl. This study collected 20 Fici Hirtae Radix commercial medicines mixed 40% non-medicinal parts samples. TLC data, morphological characteristics and microscopic characteristics, both showed obvious distinction. The concentration of psoralen and bergapten showed the content of psoralen range from 0.00848% to 0.150%, and the content of bergapten range from 0.00587% to 0.026 3%, and the contents of two index components of Fici Hirtae Radix were significantly higher than the non-medicinal parts samples. The moisture content ranged from 4.73% to 8.27%, total ash ranged for 2.58% to 4.37%, acid insoluble ash ranged for 0.054% to 0.710%, ethanol-soluble extracts ranged for 6.23% to 8.34%. Conclusion: This paper revised the origin error of Fici Hirtae Radix of Chinese Pharmacopoeia (1977 edition) that its specification medicinal part should be the roots of F. hirta, and established quality standards of Fici Hirtae Radix, and these methods could comprehensively and effectively control the quality of commercial medicinal materials of Fici Hirtae Radix. This study could provide evidence for rational, safe, and effective clinical application of Fici Hirtae Radix.

OBJECTIVETo investigate the type 2 diabetic patient's periodontal condition and to analyze the influencing factors of periodontitis.

METHODSA total of 182 type 2 diabetic patients were included in the survey and requested to fill out a questionnaire, and their periodontal status was evaluated by measuring probing depth (PD), attachment level (AL), sulcus bleeding index (SBI), simplified oral hygiene index (OHI-S).

RESULTSThe prevalence of periodontitis in this group of patients was 96.7% (176/182), including 20 patients with mild periodontitis, 156 with moderate to advanced periodontitis. The mean PD and AL of the 182 patients were (2.92 +/- 0.67) mm and (2.87 +/- 1.31) mm. At least one tooth was lost in 57.1% (104/182) of the patients. The factors related to periodontitis were age, gender, smoking, living in town or country, and 2 h plasma glucose of oral glucose tolerance test (OGTT). There was no relationship between the severity of periodontitis and education level. The majority of patients did not receive any periodontal therapy.

CONCLUSIONSPeriodontal status was bad in patients with type 2 diabetes. It is important to develop an education program on oral health for type 2 diabetic patients.

OBJECTIVETo observe monocyte (Mo) development in wild type C57BL/6 mice and apoE gene knockout (apoE(-/-)) mice, and to evaluate the immuno-regulatory effect of Huanglian Jiedu Decoction (HJD) on peripheral Mo development in apoE(-/-) mice.

METHODSFour, 8, 12, and 16 weeks old female C57BL/6 mice were set up as control groups of different ages, while 4, 8, 12, and 16 weeks old female apoE(-/-) mice were set up as hyperlipidemia groups of different ages. Four-week old female C57BL/6 mice were recruited as a blank group. Four-week old female apoE(-/-) mice were randomly divided into the control group, the Western medicine group, and the Chinese medicine group by paired comparison, 5 in each group. Equivalent clinical dose was administered to mice according to body weight. Mice in the Western medicine group were administered with Atrovastatin at the daily dose of 10 mg/kg by gastrogavage, while those in the Chinese medicine group were administered with HJD at the daily dose of 5 g/kg by gastrogavage. Body weight was detected each week. After 4 weeks blood lipids levels (such as TG, TC, LDL-C, and HDL-C), and the proportions of Mo and Ly6c(hi) were detected.

RESULTSCompared with 4-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05). Levels of TC and TG, and the proportion of Ly6c(hi) subtype increased, but the proportion of Mo de- creased in 8-week-old apoE(-/-) mice (P <0. 05). Levels of TC, TG, and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05). Levels of TC, TG, LDL-C, and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with 8-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05); levels of TC and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05); levels of TC and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with C57BL/6 mice of the same age, TC and TG increased, HDL-C decreased (P < 0.01) in 4-and 8-week-old apoE(-/-) mice (P < 0.01); levels of TC, TG, LDL-C increased, and HDL-C level decreased in 12- and 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01); the proportion of Mo increased in 4-week-old apoE(-/-) mice (P < 0.05); proportions of Mo and Ly6c(hi) increased in 8-week-old apoE(-/-) mice (P < 0.05). Compared with the blank control group, levels of TC, TG, and LDL-C, proportions of Mo and Ly6c(hi) increased (P < 0.01, P < 0.05), but HDL-C level decreased (P <0. 01) in the control group after intervention. Compared with the control group, body weight gained less in the Western medicine group and the Chinese medicine group (P < 0.05); the proportion of Ly6c(hi) subtype decreased in the Chinese medicine group (P < 0.05).

CONCLUSIONSIn development process blood lipids levels in apoE(-/-) mice are not only associated with age. Blood lipids levels induced growth changes in natural immune system are also correlated with age. In early stage of lipids development HJD intervention could correct this special immune disorder in apoE(-/-) mice.
