There are two systems as the red channel system and the white channel system carved or painted on the wooden figurine ofof Benque school. The two systems are horizontally staggered each other without overlapped. The red channel system, similar towooden figurine, have channels, but without points. For the white channel system, the running courses of channels result from the sensation distributions of the points after optional stimulation. Thewooden figurine focuses on the illustration of the white channel system, named as white channel figurine. Compared with thered channel figurine, together with examples, such as the running course of the white channel related to the meridian of heart-transfer-point, the white channel related to the belt vessel linking to lung-transfer-point, stomach-transfer-point and kidney-transfer-point, as well as the corresponding photographs. It is indicated that thewhite channel figurine is a training aid for testing the sensation marching along channel (SMC) caused by transfer-point stimulation. The white channel system is a flexible way of channel. The study aims to observe the/SMC reaching the affected area and contributes to clinical practice. This discovery is not related to the "intermediate link theory" in the Yellow Emperor meridian system.

Objective To investigate the correlation of previous hepatitis B virus (HBV) infection with the incidence risk of chronic pancreatitis (CP).Methods This was a case control study.Five hundred and seventy-one patients with CP admitted in the Department of Gastroenterology, Changhai Hospital, Second Military Medical University between January 2015 and October 2016 were enrolled, and 1216 sex and age matched health individuals were also enrolled as the control group.The 5 serum HBV markers(HBsAg,HBsAb, HBeAg, HBeAb and HBcAb) were detected and their correlation with CP incidence was analyzed.Results The positive rate of HBsAg in the CP group and the control group were 3.0% and 3.8%, respectively, and the difference was statistical significant.(OR=0.039, 95% CI 0.02~0.80, P<0.00), but in all the HBsAg positive models (HBVM) the difference of CP and control groups was not statistical significant.HBsAb positive rate in CP group and the control group were 51.8% and 75.0%, respectively, and the difference was statistical significant(P<0.000).HBeAg positive rate in CP group and the control group were 1.1% and 0.1%, the difference was statistical significant (P<0.05), but in all the HBeAg positive models, the CP group and the control group had no statistical difference (P>0.05).The positive rate of HBeAb in the CP group and the control group were 24.3% and 10.8%, respectively, and the difference was statistical significant(P<0.00).The positive rate of HBcAb in the CP group and the control group were 50.1% and 16.5%, respectively,and the difference was statistical significant(P<0.000).In the(HBsAb+, HBeAb+, HBcAb+), (HBsAb+, HBcAb+), (HBeAb+, HBcAb+), (HBcAb+) models, the positive rate in CP group was significantly higher than that of the control group(P<0.000).Multivariate regression analysis showed that the positivity of HBsAb and HBeAb were the protection factors for the occurrence of CP(P<0.05),and HBcAb positivity was the independent risk factor for CP (OR=6.931,P<0.000).Conclusions HBsAb and HBeAb poitivity were the protectors for CP, while HBcAb positivity could be considered as an independent risk factor for CP.

[ABSTRACT]OBJECTIVETo evaluate the diagnostic value and curative effect of keyhole neurovascular decompression with local anesthesia for vestibular paroxysmia.METHODSOf 40 patients with trigeminal neuralgia, hemifacial spasm and glossopharyngeal neuralgia, 8 of them combined with vestibular paroxysmia underwent keyhole neurovascular decompression under local anesthesia to explore the vascular compression of acoustic nerve root and have the neurovascular decompression. The evaluation of the vertigo after operation was performed with symptom report card. The patients were followed-up for 36 to 61 months. RESULTSThe vessels compressing the root zone of the vestibular nerve were found in 8 patients with vestibular paroxysmia, of whom 7 patients had the vascular compression vertigo induced during operation and the vertigo was disappeared after operation, moreover, one patient had no vascular compression vertigo induced during operation and the vertigo was not changed after operation. With the average follow-up of 57 months, of 8 patients with vestibular paroxysmia, 7 patients had no recurrence of the vertigo, and the effective control rate was 87.5%.CONCLUSION Local anesthesia keyhole neurovascular decompression was not only an effective way for treating vestibular paroxysmia and controlling the vertigo, but also had certain clinical significance in the diagnosis of vestibular paroxysmia.

Objective To investigate the efficacy and safety of different optimal therapy strategies for hepatits B e antigen (HBeAg) positive chronic hepatitis B (CHB) patients with suboptimal response to peginterferon-α-2a (peg-IFN-α-2a) at 24 weeks.Methods This open-label,single-center and prospective clinical observational study was conducted in Department of Infectious Diseases at Shanghai Changhai Hospital between January 2009 and December 2011.The cases of HBeAg-positive CHB with suboptimal response to peg-IFN-α-2a at week 24 were enrolled.Based on virological markers and patient preference,patients were treated with either peg-IFN-α-2a add-on adefovir dipivoxil (ADV) or switch-to telbivudine (LdT).Hepatitis B virus (HBV) virological and serological data were collected at week 12,24 and 48 after the initiation of optimal therapy.Adverse reactions were also monitored.Therapeutic efficacy was compared between two groups of patients before and after treatment by x2 test.Kruskall Wallis test and Mann-Whitney test were used for analysis of continuous variables.Results Among 193 HBeAg positive CHB patients treated with interferon,67 had suboptimal response and were enrolled.Forty five cases received peg IFN-α-2a add-on ADV treatment and 22 cases received switch-to LdT treatment.After 48 weeks of optimized therapy,the total tBeAg seroconversion rate was 25.3 ％.The rates of HBeAg loss,HBV DNA negative and alanine aminotransferase normalization were 26.8％,73.1％ and 83.5％,respectively.The peg-IFN-α-2a switch-to LdT strategy had better HBV DNA inhibition efficiency compared with the peg-IFN-α-2a add-on ADV strategy at week 12,24 and 48 (P=0.00,0.00 and 0.01,respectively).However,there was no significant difference of HBV DNA negative rate between two groups at week 48 (x2 =0.01,P=0.89).The obviously intolerable adverse reaction was not reported in two optimized strategy groups.Conclusions The 48-week optimized treatment for HBeAg positive CHB with suboptimal response to peg-IFN-α-2a at week 24 could achieve a higher HBeAg seroconversion rate.The switch-to LdT strategy may have better HBV DNA inhibition efficiency.Both strategies show satisfactory safety and tolerance.

Objective: To study the distribution of levofloxacin in the serum and ascites in patients with cirrhosis and to evaluate its efficacy in treatment of patients with spontaneous bacterial peritonitis(SBP). Methods:（1）Concentration of levofloxacin in the serum and ascites was detected with HPLC in 7 patients with cirrhosis at different time (in the serum: 0.5, 1, 1.5, 2 and 12 h;in the ascites:2, 4, 6 and 12 h). （2）The effects of levofloxacin were observed in treatment of 30 patients with SBP. Results:（1） Levofloxacin was determined in serum and ascites of patients with cirrhosis, whose concentration depended on the duration after oral administration. In serum: tmax was 1.5 h and cmax was (3.913±1.388) μg/ml. In ascites: tmax was 6.0 h and cmax was (2.520±1.213) μg/ml. The levels decreased gradually after reaching peak concentration, then stabilized from 12 h.（2）The symptoms and signs were significantly improved in patients with SBP treated with the levofloxacin. Conclusion: After the oral administration, levofloxacin can both distribute in serum and ascites, and it is efficient in the treatment of the patients with SBP.

ObjectiveTo investigate the effects of the imbalance between regulatory T cells (Treg) and T helper 17 cells (Th17) in patients with chronic hepatitis B virus (HBV) infection.MethodsThe serum concentration of Treg/Th17 differentiation-related cytokines in 34 patients with chronic hepatitis B (CHB),20 patients with HBV related acute on chronic liver failure (ACHBLF),and 20 healthy controls (NC) were measured by enzyme-linked immunosorbent assay (ELISA) and proportion of peripheral Th17 and Treg cells were analyzed by flow cytometry.Numeration data was analyzed by Fisher's exact propability method and measurement data was tested by one-factor analysis of variance or Turkey multiple comparison.Results The levels of Th17 differentiation-related cytokines,II-1β (3.97±2.85) pg/mL,IL-6 (12.75±-8.87) pg/mL,and IL-21 (360.0±335.7) pg/ mL in patients with ACHBLF were significantly increased than those in NC,which were (1.87 ±0.94) pg/mL(q=4.559,P＜0.01),(5.28±0.72) pg/mL(q=7.309,P＜0.01) and (46.68±20.17) pg/mL(q=6.946,P＜0.01 ),respectively.The proportion of Th17 increased markedly in patients with ACHBLF than that in NC(q=3.972,P＜0.05).However,compared to NC and patients with ACHBLF,the Treg differentiation-related cytokine,TGF-β,in patients with CHB,increased significantly (q=4.536 and 5.323,respectively; both P＜0.01).And the population of Treg also increased markedly in CHB patients.The level of IL-17A which was the characteristic effector cytokine of Th17 was the highest in patients with ACHBLF.The peripheral Th17 cell proportion was positively correlated with the level of serum total bilirubin in patients with ACHBLF (γ=0.74,P＜0.01).Conclusions Th17 and Treg imbalance including cytokine profiles and cell numbers exists in patients with chronic HBV infection.The Th17 are active in patients with ACHBLF and Treg are active in patients with CHB.

Objective To analysis the relationship between of waist-to-height ratio(WHtR) and the non-alcoholic fatty liver disease(NAFLD).Methods A total of 7 896 were selected as observed subjects from the Kailuan Group in 2011-2012 health physical examination.A questionnaire survey,blood biochemical and abdominal ultrasound examination were finished by trained medical staff.According to previous study recommended cut points the observed subjects was divided into two groups:abdominnal obesity group(WHtR≥0.5,n=3 185) and non-abdominnal obesity group(WHtR<0.5,n=479).According to the WHtR and its quartile,the observed subjects was divided into four groups(first(WHtR<0.47),second(0.47≤WHtR<0.51),third(0.51≤WHtR<0.55) and forth(WHtR≥0.55) quartile groups).NAFLD detection rate of the four groups were Compared.Multiple Logistic regression analysis was used to analyze the influencing factors of the NAFLD.Results (1)The detection rate of NAFLD in abdominnal obesity group was higher than that in non-obesity group(62.7% vs.21.5%,P<0.01).Along with increasing WHtR level in the 4 quartile groups,the incidence of NAFLD was progressively increased,being 12.6 %,38.1%,57.5% and 72.5% respectively in the total population.After stratified by gender,15.1%,40.6%,59.6% and 75.0% in male,7.8%,31.5%,48.3% and 63.8% in female.In the same WHtR group,the NAFLD detection rate of male was higher than female,the differences were statistically significant(P<0.01).(2)Multiple logistic regression analysis showed that compared with the first quartile group,the second,third and forth quartile groups had increased risk of NAFLD after adjusting age,gender and other risk factors,the OR value being 3.19,5.93 and 9.81 in the total population.After adjusting above factors,the OR value being 3.12,6.02 and 10.45 in male,3.32,5.37 and 7.57 in female,respectively.Conclusion The incidence of NAFLD is increased along with the increasing the WHtR.

Objective To investigate the effects of waist-to-hip ratio (WHR) on the formation of carotid plaque in the middle-aged and elderly people.Methods A total of five thousand and ninety-nine participants who have taken physical examination in Tangshan Kailuan Company from June 2010 to October 2011(above 40 years old,no previous history of ischemic stroke,transient ischemic attack,myocardial infarction) were enrolled in this study.Questionnaire survey,blood biochemical and carotid artery ultrasound examination were used to examine the subjects.According to WHR,quartile division was used to divide the subjects into four groups.The detection rates of carotid plaque among the 4 groups were compared.Multivariate logistic regression analysis was used to analyze the factors effecting carotid artery plaques.Results (1) The detection rate of carotid artery plaque increased with the increase of WHR,the rates of the first,second,third and fourth group were 20.7% (571/2 753),21.9% (604/2 753),27.5% (758/2 753) and 29.8% (820/2 753) respectively.The difference was statistically significant(P=0.000).(2) Logistic regression model was used to analyze multiple factors affecting the detection rate of carotid plaque.After the correction of other factors,compared with the first group,the carotid artery plaque detection rate in the second,third,fourth group were all increased,the OR values were 1.23(95%CI:1.10~1.54),1.65(95%CI:1.52~2.13),1.67(95%CI:1.54~2.17),respectively.Conclusion The increased WHR in the middle-aged and elderly population may increase the risk of carotid plaque formation.

Objective To examine the sleep status and relevant psychosocial factors in patients with colorectal cancer before surgery and improve their sleep quality. Methods A cross?sectional survey method was used. Participants were 107 cases of patients with colorectal cancer from the Department of Anorectal Surgery in The First Hospital ,which is affiliated with China Medical University. The Athens insomnia scale(AIS),Ham?ilton depression scale(HAMD),Hamilton anxiety scale(HAMA),perceived social support scale(PSSS),self?esteem scale(SES),medical cop?ing questionnaire(MCMQ),memorial University of Newfoundland scale of happiness(MUNSH),Eysenck personality questionnaire(EPQ),and Wong?Baker face scale were used to assess preoperative sleep in patients with colorectal cancer and related psychosocial factors. Results Among the 107 cases,there were 24 cases of insomnia,with an insomnia incidence of 22.43%. No statistical differences were found in demographic charac?teristics and clinical characteristics(P>0.05). According to the degree of insomnia,there were significant differences between groups(P<0.05) for depression,anxiety,social support,avoidance,yield,happiness,and EPQ?N. Before the surgery,the degree of depression,anxiety,and EPQ?P had a significant positive effect on the degree of insomnia (P< 0.05). Conclusion The degree of insomnia before surgery in patients with colorectal cancer is closely associated with depression,anxiety,coping styles,social support,and personality characteristics.
