Objective To observe the effects of hot compress on oxaliplatin-induced neurotoxicity.Methods One hundred and twenty patients undergoing chemotherapy with oxaliplatin enrolled in this study were randomly assigned to the control group and expenment group.The control group was given routine health education and the experiment group was treated with hot compress.We compared the incidence of nerotoxocity after 2 and 4 treatment courses.Resulsts The incidence of neurotoxiticity was 75.0%in the experiment group and 91.7%in the control group after 2 treatment courses(P<0.01).The incidences were 86.7%in the experiment group and 98.3%in the control group after 4 treatment courses(P<0.001).Conclusion Hot compress can effectively reduce the incidence of neurotoxicity induced by chemotherapy with oxaliplatin.

Eubhorbia neriifolia L. is a plant of Euphorbia family.Five known lignans were isolated from the aerial parts of E. neriifolia L. by silica gel for column chromatography and preparative high-performance liquid chromatography (HPLC).Their potential antitumor activities were evaluated in vitro.Compound 2 exhibited proliferation inhibition and cytotoxicity against esophageal squamous cancer cells, especially KYSE-410 and KYSE-450 cells.Further analyses showed that compound 2 could significantly induce apoptosis through the activation of caspase 3/9 and down-regulation of the Bcl-2/Bax protein ratio.These results suggested that compound 2 had a significant inhibitory effect on the esophageal squamous cancer cells, especially KYSE-410, which deserves further research as a potential antitumor agent.

The cholinesterase(ChE)and lactate dehydrogenase(LDH)activities in blood smears of 37 patients were observed before and 20 minutes after electroacupuncture.Hegu and Zusanli were mainly chosen as the acupuncture points.Karnovsky method was used to demonstrate ChE,activity,and tetrazolium-formazan reaction for LDH activity. Before acupuncture,all formed elements of blood showed both ChE and LDH acti- vities.In red blood cells ChE and LDH activities were localized at the cell membrane, while in white blood cells they were found throughout the cytoplasm as colored granu- les.The granulocytes showed greater ChE and lesser LDH activities than the lymph- ocytes.The platelets also showed greater LDH and ChE activities,especially the former. On the whole,platelets and leucocytes,as compared with erythrocytes,showed greater activities for ChE and LDH. Under microscopic observation,according to the amount and color of granules,the degrees of GhE and LDH activities for each kind of blood formed elements before and after acupuncture were recorded as different markes,such as +、++、+++ and so on.The degrees of GhE or LDH activity in various formed elements of blood were compared by means of statistical tests.After acupuncture,both GhE and LDH activities of all blood formed elements were increased(p

70 patients including 60 cases under acupuncture anesthesia and 10 cases under drug anesthesia were observed. Before and 20 minutes after acupuncture the blood samples were taken from the patient ear lobes respectively, and in some patients taken once again 24 hrs after acupuncture. The electroacupuncture point Hegu or Zusanli was mainly adopted. As the method for detection of cell-mediated immunity(CMI) in vitro the improved microtechnique of whole blood for E-rosette (active and nonactive) and lymphocyte transformation tests was used. In performance of active rosetting the total leucocyte count and the differential lymphocyte count were done for calculation of absolute number of active rosette forming cells (RFC). The mean value of increase of active RFC was 12.7?1.43, the decrease was 6.8?1.77 after acupuncture. The increment of the absolute number of active RFC was 175?63.59. However no marked effect on the drug anesthesia group was found. In the lymphocyte transformation assay the increase was 12.7?1.49, the decrease was 7.0?2.19, and the enhancement effect still exhibited 24 hrs after acupuncture. In these tests an increase was mostly found in those with a lower or a usual CMI level; a decrease often found in those with a higher CMI level prior to acupuncture. The increase or decrease level in the results of three kinds of test (active, nonactive RFC and lymphocyte transformation) was similar, the increase range was 12～13%, the decrease range 6～7%. As the former compared with the latter, the promotion was prominent by all means.

Objective To explore the expressions and significance of miRNA - 101,enhancer of ZESTE homo-log 2(EZH2)and transforming growth factor(TGF)- β1 in the kidneys with complete uniateral ureteral obstruction (CUUO). Methods Thirty male SD rats,(6 ± 1)weeks old,weighted(150 ± 10)g,were divided into sham group, 7 - day group with CUUO and 14 - day group with CUUO by using random number table method,10 rats in each group. The obstructed kidney samples were collected in 7 and 14 days,respectively,for detecting the expression of miRNA -101 by real time - polymerase chain reaction(RT - PCR)and TGF - β1 and EZH2 protein by Western blot,immuno-histochemistry and hematoxylin - eosin staining. Their correlated expressions were analyzed. Results RT - PCR results showed that the expressions of miRNA - 101 in sham group and 7 - day group with CUUO were(12. 69 ± 1. 60)times and(3. 74 ± 1. 24)times which were higher than those of 14 - day group with CUUO,respectively,there was a signifi-cant difference among these 3 groups(P ﹤ 0. 05). The expressions of TGF - β1 and EZH2 proteins were 1. 14 ± 0. 12, 1. 04 ± 0. 14,0. 76 ± 0. 18 and 1. 04 ± 0. 04,0. 89 ± 0. 03,0. 73 ± 0. 02 in 14 - day group with CUUO,7 - day group with CUUO and sham group,respectively. There was a negative correlation between miRNA - 101 with EZH2( r =- 0. 92,P ﹤ 0. 05),and negative correlation with TGF - β1(r = - 0. 63,P ﹤ 0. 05),and positive correlation between EZH2 and TGF - β1(r = 0. 67,P ﹤ 0. 05);the expressions of miRNA - 101,EZH2 and TGF - β1 were associated with each other in obstruction renal in different time periods. Conclusions With the extension of obstruction time, miRNA - 101 expression decreased,EZH2 and TGF - β1 expression increased,evidently,which indicates that the de-velopment of renal interstitial fibrosis may be affected through regulating EZH2 expression of renal obstruction through miRNA - 101 in the young rats.

Objective To observe any effect when eye acupuncture is combined with computer-assisted cognition training to ameliorate cognitive dysfunction after stroke.Methods Stroke patients with cognitive impairment were randomly divided into an eye acupuncture group (n=30),a computer group (n=30) and a combination group (n=30).The eye acupuncture group was given eye acupuncture,the computer group was given rehabilitative cognition training with specialized equipment and the combination group was given both eye acupuncture and the computeraided training.The treatment lasted 2 months.The Loewenstein occupational therapy cognitive asessment (LOTCA)and the modified Barthel index were used to evaluate the patients' cognitive function and daily life ability before and after treatment.Results Before training there was no significant difference in average LOTCA and MBI results among the three groups.After 2 months of training,all three groups had significantly higher scores in both evaluations.Moreover,the combination group's average score on organization ability,perceptual ability,thinking operation ability and concentration,and also their average total score and MBI score were significantly better than those of the other two groups.Conclusions Eye acupuncture combines synergistically with cognitive rehabilitation training to ameliorate cognitive dysfunction after stroke.Together they promote cognition,ADL ability and an early return to normal family and social life better than either alone.

Objective To optimize immunodominant protein combinations for serological screening for Cblamydia trachomatis (Ct) infection.Methods Both serum and genital swab samples were collected from 50 patients with Ct infection confirmed by colloidal gold immunochromatographic assay (GICA),and 30 GICA-negative clients without Ct infection at a sexually transmitted disease (STD) clinic in Tianjin Medical University General Hospital.The 30 serum samples from GICA-negative clients were also negative for microimmunofluorescence (MIF) assay.Eight Ct immunodominant proteins,including Pgp3,CPAF,CT143,CT101,CT694,CT875,CT813 and IncA,were selected as antigens to detect corresponding antibodies in the serum samples by enzyme-linked immunosorbent assay (ELISA) with the Ct proteins Hsp60 and major outer membrane protein (MOMP) as references.The results of ELISA were compared with those of the traditional gold standard method MIF assay to determine the immunodominant protein combination with the highest sensitivity and specificity.Results Of the 50 serum samples from patients with Ct infection,44 were positive and 6 negative by MIF.The results of ELISA with the combination of immunodominant proteins Pgp3,CT694 and CT875 as antigens were 97.73％ (43/44) consistent to those of MIF assay.Of the 30 serum samples from GICA-negative clients,all were negative by MIF.Meanwhile,no antibody was detected against any of the immunodominant proteins Pgp3,CT694 and CT875 in any of the serum samples from GICA-negative clients.Conclusions The ELISA with the combination of immunodominant proteins Pgp3,CT694 and CT875 as antigens has good sensitivity and specificity for serological screening for Ct infection,and is simple to operate and easy to popularize.

Objective To investigate the effect of C-erbB-2 shRNA on chemosensitivity of mouse lung adenocarcinoma cells and its mechanism,and to find new therapy method for non-small cell lung cancer,especial lung adenocarcinoma.Methods The mouse lung adenocarcinoma Lewis cells were cultured regularly and divided into non-transfected group, pGPU6/RFP/Neo-shNC group and pGPU6/RFP/Neo-erbB-2 group. The plasmids were synthesized and transfected into Lewis cells in each group by Lipofectamine 2000.The expression levels of C-erbB-2 mRNA and protein in the cells in various groups were tested by RT-PCR and Western blotting method, respectively. The Lewis cells were divided into non- transfected group, pGPU6/RFP/Neo-shNC group, carboplatin group, pGPU6/RFP/Neo-erbB-2 group, pGPU6/RFP/Neo-shNC+carboplatin group and pGPU6/RFP/Neo-erbB-2+ carboplatin group. The apoptotic rates of the cells in each group were detected by flow cytometry;the expression levels of Bcl-2 and Bax proteins in each group were determined by Western blotting method.Results The expression levels of C-erbB-2 mRNA and protein in pGPU6/RFP/Neo-erbB-2 group were lower than those in non-transfected group and pGPU6/RFP/Neo-shNC.The apoptotic rate of the cells in pGPU6/RFP/Neo-erbB-2+carboplatin group was the highest in all of the groups (P<0.01);compared with the others, the expression of Bax protein in pGPU6/RFP/Neo-erbB-2+carboplatin group was increased, while the expression level of Bcl-2 protein was decreased.Conclusion C-erbB-2 shRNA can increase the Lewis cells’sensitivity to carboplatin.The mechanism may be that it can enhance the Lewis cells’apoptosis induced by carboplatin through increasing the expression of Bax protein and decreasing the expression of Bcl-2 protein.

Objective To explore the effects of home rehabilitation manual on rehabilitation of patients undergoing anterior cruciate ligament reconstruction. Methods A total of 118 cases of patients with anterior cruciate ligament reconstruction were randomly divided into the intervention group and the control group from May 2014 to May 2015, with 56 cases in the intervention group and 62 cases in the control group. Patients in the control group received routine discharge guidance and follow-up, while patients in the intervention group, received an assessement on nursing problems by Omaha system 1 d before discharge. We made home rehabilitation manuals according to problems, and provided systemic professional guidance from their diet and activities, use of crutch and leg holder, the intervention of pain and swelling, the neuro-musculo-skeletal function training, and the nursing management of anxiety and sleeping disorders. The rehabilitation effect in two groups before surgery and 12 weeks after surgery were compared by Lysholm score. The improving effect of main nursing problems in knowledge, behavior and situation 1 d before discharge, and 2 weeks, 4 weeks, 8 weeks, 12 weeks after surgery between two groups were compared. Results There was no significant difference in the knee joint Lysholm score before surgery ( P>0.05) . 12 weeks after surgery, the Lysholm score of the intervention group was (72.83±1.95), and it was (71.35±2.13) of the control group (t=3.792,P<0.05). After surgery, the score of knowledge, behavior, situation about the problems of pain, neuro-musculo-skeletal function, personal care, physical activity, sleep and rest patters were all increaseing with the prolonged of time, and the score of the intervention group was higher than that of the control group ( P<0. 05 ) . Conclusions Home rehabilitation manual can improve the score of knowledge, behavior and situation about the main nursing problems of patients with anterior cruciate ligament reconstruction. It also can raise the Lysholm score of patients, and promote the rehabilitation.

Objective:To determine whether amoxicillin had an effect on the enamel mineralization of SD rats.Methods:Eighteen SD rats were randomly divided into three groups. The rats in the control group were given distilled water. The rats in two experimental groups were administered 50 or 100 mg/kg amoxicillin by intragastric administration from day 3 to day 17 after birth. The general condition, the structure of liver and kidney, the enamel surface changes of mandibular first molars and incisors were observed. The changes of Ca/P ratio on enamel surface were analyzed by X-ray energy dispersive spectrometer (EDS). The surface morphology after phosphoric acid treatment was examined by scanning electron microscopy (SEM). Histological changes in the ameloblasts of mandibular incisors were analyzed by hematoxylin and eosin (HE) staining.Results:Compared with the control group, the general conditions as well as liver and kidney structures of SD rats in 50 and 100 mg amoxicillin groups had no significant differences. There was no obvious chalky changes on the first mandibular molars of SD rats in each group. All the incisors in 50 and 100 mg groups showed different degrees of chalkiness in the labial incisal 1/3 enamel. X-ray EDS analysis showed that the Ca/P ratios of occlusal and incisal 1/3 enamel in 50 and 100 mg groups (occlusal 1/3 of mandibular first molars: 1.51±0.03 and 1.52±0.02, incisal 1/3 of mandibular incisors: 1.46±0.01 and 1.43±0.01) was significantly lower than that in the control group (occlusal 1/3 of mandibular first molars: 1.67±0.41, incisal1/3 of mandibular incisors: 1.73±0.07) ( P<0.05). However, there was no significant differences in the cervical 1/3 Ca/P ratio of mandibular first molars and incisors among the three groups (mandibular first molars: 1.56±0.04 for control group, 1.59±0.05 for 50 mg group and 1.57±0.04 for 100 mg group; incisors: 1.52±0.02 for control group, 1.47±0.01 for 50 mg group and 1.51±0.03 for 100 mg group) ( P>0.05). SEM observation showed that the enamel rods of the first molars and incisors in the 50 and 100 mg group varied in size and arranged disorderly. The spaces between the enamel rods were larger than that in the control group and some areas even appeared large pits. HE staining showed that the gaps between ameloblasts in 50 and 100 mg groups were significantly wider than that in the control group. Conclusions:Intake of amoxicillin during the period of enamel development of SD rats might affect enamel mineralization.
