The definition of rehabilitation should reflect the connotation and extension of rehabilitation medicine system,moreover,special attention should be paid to the process of translation,applications and promotion due to its derivation from Latin.The fourth edition of rehabilitation medicine textbook which published by People's Medical Publishing House described the definition of rehabilitation inaccurately,although integrated the foreign authority definitions.The definition of ‘ re-learning’has been described by the textbook without considering logical sequence,which caused difficulty in explaining and comprehending between teachers and students in class.Besides,application of another term of rehabilitation medicine in the textbook is imprudence.

Objective To study the relationship between serum hepatitis B virus covalently closed circle DNA (HBV cccDNA) as well as liver function and liver tissue pathological changes in children with chronic hepatitis B.Methods One hundred and twenty-four HBV-DNA positive children with hepatitis B were enrolled.Among 124 patients,65 cases were HBV carriers,59 cases were chronic hepatitis (mild in 31 cases,moderate in 18 cases and severe in 10 cases).HBV cccDNA in serum and liver function were detected,46 of which underwent liver biopsy and liver tissue inflammation and fibrosis grading classification was made.Results In moderate and severe cases,positive rates of serum HBV cccDNA (77.8％,100％) were higher than those of the HBV carriers and mild cases (32.3％,54.8％) (x2 =25.429,P ＜ 0.01),indicating more severe illness in children,detection rate of serum HBV cccDNA was higher.ALT,AST,and TBIL were higher in serum HBV cccDNA positive group than those of negative group[(95.6 ± 18.2) U/L vs (52.5 ± 17.7) U/L,(88.8 ±20.3) U/L vs (48.4 ±21.4) U/L,(68.4 ±24.6) μmol/L vs (28.3 ± 23.9) μmol/L](t =15.572,10.750,17.067,P ＜ 0.01).Serum HBV cccDNA and liver inflammatory activity and fibrosis showed no significant correlationship.Conclusion Serum HBV cccDNA is a sensitive indicator of viral replication,the more severe the disease situation,the peripheral HBV cccDNA detection rate is higher.But it is not entirely consistent with liver inflammation and fibrosis,so it can not completely reflect the degree of liver damage.

OBJECTIVETo observe the effect of electroacupuncture (EA) combined with ultraviolet therapy on herpes zoster at the acute stage and the impacts on serum interleukin 2 (IL-2), interleukin 6 (IL-6) and interleukin 10 (IL-10) in the patients.

METHODSThirty-four patients of herpes zoster were randomized into a medicine group and a combined therapy group, 17 cases in each one. In the medicine group, the intravenous drops with acyclovir injection, muscular injection with cobamamide and the topical with acyclovir ointment were applied. Additionally, TDP was radiated locally. In the combined therapy group, on the basis of the treatment as the medicine group, EA and ultraviolet therapy were supplemented. The duration of treatment was 10 days in the two groups. Before and after treatment, blister relief, incrustation time and the visible analogue scale (VAS) were recorded in the two groups. The clinical efficacy was assessed in the two groups and the levels of serum IL-2, IL-6 and IL-10 were determined in the two groups.

RESULTSIn the combined therapy group, the time of blister relief and incrustation was earlier apparently than that in the medicine group (both P<0.05). VAS score after treatment were reduced as compared with that before treatment in the two groups (both P<0.01), and the reducing amplitude in the combined therapy group was larger than that in the medicine group (P<0.01). The total effective rate was 94. 1% (16/17) in the combined therapy group, higher than 76.4% (13/17) in the medicine group (P<0.05). After treatment, IL-2 levels were increased as compared with those before treatment in the two groups (both P<0.05), the levels of IL-6 and IL-10 were reduced obviously as compared with those before treatment in the two groups (all P<0.01). After treatment, the levels of IL-6, IL-10 were reduced much more apparently in the combined therapy group as compared with those in the medicine group (both P<0.05).

CONCLUSIONEA combined with ultraviolet irradiation more rapidly and effectively relief the symptoms of herpes zoster, significantly relief pain, shorten the duration of sickness, improve the body immunity and reduce nerve injury.

Objective:Iris-fixed IOL implantation is a new and effective therapy for phakic eyes. Because the patients are young,they know very few about the operation,which mandated delicate pre-and postoperative nursing. This article discussed how to nurse the patients receiving iris-fixed IOL implantation operation in phakic eyes for super high myopia. Methods:Fifty eight eyes of 30 patients with super-high myopia received iris-fixed IOL (Verisyse IOL) implantation. Pre-and postoperative nursing course were summarized. Results:Focused education through preoperative visits,active cooperation in the operation and meticulous postoperative nursery were beneficial for the operation. Significant vision improvement was found after surgery. Conclusion:The planned,step by step,focused nursing course can improve the effects of operation and reduce the postoperative complication.

Objective: Breast augmentation by polyacrylamide hydrogel(PAHG) injection has resulted in a series of adverse events in many female patients.This article summarizes the authors' experience in the diagnosis and treatment of lactational infection after breast augmentation by PAHG injection and discusses related preventive measures.Methods: This study included 2 patients who had developed infection during lactation 5 years after breast augmentation with PAHG.We identified the exact position of the PAHG and vomica by color Doppler,computerized tomography and magnetic resonance.We made incisions in the submammary fold or mammary areola to take out the PAHG,drain the pus and place the vacuum pressure tube,followed by application of pressure bandages.Results: One of the patients healed without any complication,while the other developed latex leak in both breasts,but finally cured after milk regurgitation and repeated changing of dressings.Conclusion: Lactational infection after breast augmentation by PAHG injection is detrimental to female patients.Preventive measures should be taken as early as possible.For patients with this infection,operation should be performed to take out the PAHG and drain the pus.Sufficient draining and milk regurgitation are necessary to avoid latex leak.

Objective To take Ebola virus disease (EVD) as an example and analyze the capability of responding to emerging infectious diseases among medical university students in Chongqing city.Methods Medical university students of 2 094 in Chongqing were selected and investigated by cluster sampling.Questionnaire content includes social demographic information,knowledge,attitude,practice (KAP) and related factors about EVD.The variables of the respondents were described using mean and standard deviation for continuous variables and frequency distributions for categorical variables.Influencing factors were analyzed by using multiple-linear regression model.Results The average scores of KAP regarding EVD were 9.51 ±-3.97,5.93± 1.85,3.35 ±1.43,respectively.Multiple-linear regression analysis showed that the influencing factors of KAP regarding EVD were gender (x2 =0.773,P=0.000),residence (x2 =0.886,P=0.014) and health habits (x2 =0.316,P=0.008);gender (x2 =0.474,P=0.000),grade (x2 =0.118,P=0.024),residence (x2 =0.401,P=0.016) and health habits (x2 =0.307,P=0.000);gender (x2 =0.223,P=0.001),major (x2 =0.152,P=0.000) and health habits (x2 =0.231,P=0.000).Conclusion The capability of responding to emerging infectious diseases is not optimistic among medical university students.Medical universities should perform effective intervention according to the characters of different clusters.

Objective To investigate the preventive effects of epigallocatechin gallate (EGCG) on growth and metastases of orthotropic colonic cancer. Methods Forty BALB/C male nude mice were prepared for model of colonic cancer and then divided into control group and low-, medium- and high-dose of EGCG groups with 10 each. Except control group, the mice in other three groups were treated with 5, 10 and 20 mg·kg~(-1)·d~(-1) of EGCG. The effect of EGCG on growth and metastases of colonic cancer was observed. The histopathologic changes of liver and lung were observed with HE, and protein expression of NF-E2-related factor 2 (Nrf2) in cancerous tissue was detected by immunohistochemistry. RT-PCR was used to examine mRNA levels of Nrf2, UDP-glucuronosyhrans-ferase (UGT)1A, UGT1A8 and UGT1A10. Results In comparison with control group [(564±130) mg], the average weight of the tumor in low-, medium- and high-dose groups was (152±63) mg, (76±42) mg and (18±10)mg, respectively, with tumor inhibitory rate of 73.0%, 86.5% and 96.8%, respectively (all P value<0.05). There was a positive correlation between tumor inhibitory effect and dosage of EGCG (P<0.05). The protein expression of Nrf2 and the mRNA levels of Nrf2, UGT1A, UGTIA8 and UGTIA10 in three EGCG treated groups were increased significantly compared with control group (P<0.05), and there was a phenomenon of nuclear transcription of Nrf2. Conclusions EGCG can prevent local growth and metastases of orthotopic colonic cancer in a dose-dependent manner in nude mice. The inhibitory effect may be caused by inducing the expressions of Nrf2, UGT1A, UGT1A8 and UGT1A10 genes.

A new organic-soluble co-reactant of N,N,N’,N’-tetrakis(propyl)-pentanediamine (TPPD) was synthesized and co-immobilized with tris ( 2, 2’-bipyridine ) ruthenium ditetrakis ( 4-chlorophenyl ) borate ([Ru(bpy)3][4-(Clph)4B]2) on an indium tin oxide (ITO) electrode for electrochemiluminescent (ECL) study. The hydrophobicity of TPPD prevented its leakage from the electrode surface, thus the long-term stability of the ECL electrode was enhanced. The TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode exhibited strong, stable and reproducible ECL signal. The ECL signal could be quenched efficiently by phenol with a quenching efficiency of 95. 4% in the presence of 0. 1 mmol/L phenol, demonstrating the potential of the modified electrode in determination of phenolic compounds. The transient-state of the electrogenerated chemiluminescence reaction was also investigated, which revealed that the TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode had a longer lifetime than conventional TPA-Ru(bpy)2+3 co-reactant system.
