Objective To investigate influence of hohstic nursing intervention on psychological state and gastrointestinal function of patients after abdominal operation. Methods 48 patients undergoing abdominal surgery with epidural anesthesia were divided into the intervention group and the control group. Holistic nursing intervention and routine nursing were given to the two groups respectively. Self-rating anxiety scale (SAS) and serf-rating depression scale (SDS) were used to evaluate the psychological state of all patients and gastrointestinal tract function were also measured. The result underwent t test. Results SAS and SDS scores were lower on the fifth day after operation and the time of borborygmus recovery, anal exsufflation and defecation was shorter in the intervention group when compared with those of the control group. Conclusions Hohstic nursing to patients after abdominal surgery can eliminate anxiety and depression and improve recovery of gastrointestinal tract function.

AIM:To investigate the differences of clinical signs and pathological structure of unilateral nasal pterygium and unilateral double pterygium.METHODS:Retrospective study.Totally 11 unilateral nasal pterygium and 11 unilateral double pterygium were collected to observe the size of the tissue area, the classification of blood vessels, the transparency and the break-up time of tear film.The 11 surgically excised double pterygia (11 eyes) and 6 samples of normal conjunctiva were collected for the study.With 40g/L paraformaldehyde fixation, paraffin sections were stained with Haematoxylin-Eosin, to observe the differences with nasal and temporal pathology under light microscope.RESULTS:In unilateral double pterygium, the tear break-up time was significantly shorter than that of unilateral nasal pterygium (t=3.410, P=0.003).In unilateral nasal pterygium, there was a significant negative correlation between tear film break-up time and tissue size(r=-0.927, P<0.01) and transparency(r=-0.764,P<0.01).In unilateral double pterygium, the tear break-up time was significantly negatively correlated with the growth time (r=-0.661, P<0.05), tissue size (r=-0.775, P<0.01) and transparency (r=-0.671,P<0.05).In unilateral double pterygium, compared with the temporal side, the quantity of the layers of corneal epithelial cells (t=-7.351, P<0.05), vessels (t=-7.400, P<0.05) and inflammatory cells (t=-7.481, P<0.05) increased.CONCLUSION:Compared with unilateral nasal pterygium, the tear film break-up time of unilateral double pterygium was poor.In unilateral double pterygium, with high activity, the degree of proliferation of squamous epithelium, hyperplasia and inflammatory reaction are significantly higher than those of the temporal side.

Objective To establish human choriocarcinoma JeG-3 cell line resistant to floxuridine (FUDR)and describe the characteristics of this FUDR-resistant subline.The thymidylate synthase (TS) expression level in FUDR-resistant subline was also discussed.Methods The FUDR-resistant sub-line JeG-3/FUDRA was established by intermitted exposure to grads increased FUDR.Reversed microscope was used to observe the morphological changes in FUDR-resistant sub-line.Population doubling time was calculated and compared based on the growth curve of these two cell lines,cell cycles and chromosomal ploidy were assayed with flow cytometry methods.The chemo-luminescence assay was used to detect the hormone secretion by two kinds of cell lines.The resistant index (RI) was measured by cell counting kit-8 (CCK-8)assay.Quantitative RT-PCR was used to detect the mRNA expression level of TS and we also detected the TS mRNA expression level in different doses exposed subline.Results The RI of JeG-3/FUDRA was 31.62.Compared with the JeG-3 cell,the FUDR-resistant cell line had gross changes in morphological,cell growth,cell cycles and chromosomal numbers.The ability of human chorionic gonadotrop(hCG) and progesterone secretion was lower in JeG-3/FUDRA subline.The trend of TS mRNA expression was:while exposed to low concentration of FUDR,the TS mRNA expression level was downregulated,then followed the increasing dose of the drug,the expression level of TS mRNA ascended gradually.When the terminal concentration was reached,the expression level of TS mRNA in JeG-3/FUDRA subline was higher than that of JeG-3 cell line (P＜0.05).Conclusions We established the FUDR-resistant subline of JeG-3 successfully.The TS mRNA expression level is stage-related to the different concentration and different phase in FUDR exposure.Our data suggested that TS mRNA expression level may not be used as a biomarker to predict the chemosensitivity in FUDR-based chemotherapy.

In order to investigate the antiviral effect of chinonin against Herpes simplex virus (HSV), the encephalitis model in mice and skin infection model in guinea pigs were established by HSV- I and HSV-II infection respectively. Acyclovir was used as the positive reference drug to evaluate the antiviral capacity of chinonin. Chinonin showed an obvious therapeutic effect on encephalitis in mice at doses of 25 and 50 mg/kg. At both dosages, chinonin demonstrated stronger protection than acyclovir (1 and 5 mg/kg) to the infected mice from death. It was also found that chinonin could treat the skin infection in guinea pigs effectively. The therapeutic effect of chinonin was similar to that of acyclovir (5 mg/kg) at 25 mg/kg but obviously better than that at 50 and 75 mg/ kg. In conclusion, chinonin is a potential candidate for the treatment against HSV.

Objective To examine the complement component 1 Q subcomponent-binding protein (C1QBP) gene expression in human resistance choriocarcinoma cell lines and its parental cell line JeG-3,and to investigate whether silence C 1QBP by small interference RNA could reverse the resistance of human resistance choriocarcinoma cell lines to its relevant chemotherapy drugs.Methods Expression of C1QBP mRNA and protein in cells were detected by real-time fluorogenic quantitative PCR and western blot,respectively.The difference of C 1QBP expression was compared between human resistance choriocarcinoma cell lines and its parental cell line JeG-3.Sub-cellular location was proved by confocal immunofluorescence microscopy.A lentiviral vector containing short hairpin RNA (shRNA) targeting C 1QBP was constructed and cotransfected with the packaging plasmid mixture into 293T cells by lipofectamine 2000.The human resistance choriocarcinoma cell lines were infected with the packaged lentivirus.Real-time fluorogenic quantitative PCR and western blot were used to validate whether the C 1QBP gene expression was silenced.The cell counting kit 8(CCK8)was used to determine the drug sensitivity.Results (1)The C1QBP mRNA expression levels among four human resistance choriocarcinoma cell lines[JeG-3/floxuridiuum (FUDR),JeG-3/methotrexate (MTX),JeG-3/etoposide (VP),JeG-3/dactinomycin (KSM)] were 2.520±0.680,1.770±0.230,1.940±0.090 and 1.740±0.350 folds compared to that in JeG-3 cells.The C1QBP protein was higher expression level in human resistance choriocarcinoma cell lines than that in JeG-3.The immunofluorescence methods and confocal analysis showed that C1QBP localized predominantly in the mitochondrial matrix.(2)The C1QBP mRNA expression in JeG-3/FUDR cells after infected with lentiviral vector were decreased by 93.1％ (P＜0.01).The protein expression of C 1QBP in JeG-3/FUDR cells after infected with lentiviral vector were almost completely suppressed.The resistance indexes of four human resistance choriocarcinoma cell lines(JeG-3/FUDR,JeG-3/MTX,JeG-3/VP,JeG-3/KSM) were respectively 86.3％,93.9％,92.8％ and 89.9％,which were decreased remarkably by knockdown the C 1QBP expression (P＜0.05).Conclusions C1QBP is overexpressed in human resistance choriocarcinoma cell lines compared with parental cell line JeG-3.Inhibition of C 1QBP by lentivirus-mediated small interference RNA could effectively reverses the resistance of human resistance choriocarcinoma cell lines to its relevant chemotherapy drugs.

Background It has not been reported that if the visual cortex M receptor changed during the development of myopia and how it changed if given acupuncture treatment.Objective The aim of this study was to observe the effect of electroacupuncture stimulation on the expression of acetylcholine receptors M1 (AchRM1) in visual cortex of guinea with lens-induced myopia (LIM).Methods Forty-eight three-week-old healthy guinea pigs were randomized into the normal control group,the LIM model group and the LIM electroacupuncture group.The right eyes of the guinea pigs were selected as the experimental eyes.LIM was created by monocularly wearing of-10 D lens for 4 weeks in the right eyes in the LIM model group and LIM electroacupuncture group,and then the acupuncture at the temple and hegu point was performed for 30 minutes per day for consequent 4 weeks,in the LIM electroacupuncture group.The fellow eyes of the guinea pigs were used as the self-control eyes.The refractive power and axial length were examined with retinoscopy and A-type sonography before and 4 weeks after modeling,respectively.The animals were sacrificed by excessive anesthesia at the fourth week after acupuncture and visual vertex tissue was obtained.The expression of M1 receptor mRNA in visual vertex was detected by fluorescence quantitative PCR,and the content of M1 receptor protein in visual vertex was assyed by ELISA.The study protocal was approved by Animal Ethic Committee of Shandong University of Traditional Chinese Medicine,and the use and care complied with Statement of the Association for Research in Vision and Ophthalmology.Results At the fourth week after modeling,the mean diopters were (-3.24±0.28) D and (-3.30±0.45) D in the LIM model group and the LIM eleetroacupuncture group,which were significantly higher than (0.83 ±0.86)D in the normal control group (both at P=0.000),and there was no significant difference in the diopter between the LIM model group and the LIM electroacupuncture group (t =0.200,P =0.659).The mean axial lengths were (8.67 ±0.14) mm and (8.60±0.06) mm in the LIM model group and the LIM electroacupuncture group,which were considerably increased in comparison with (8.33±0.08)mm in the normal control group (both at P＜0.05).The relative expression levels of AchRM1 mRNA in visual cortex were 0.79±0.18,1.36±0.23 and 1.13±0.13 in the normal control group,LIM model group and LIM electroacupuncture group,and the relative expression level of AchRM1 mRNA in the LIM electroacupuncture group was significantly higher than that of the normal control group and lower than that of the LIM model group (both at P＜0.05).In addition,the contents of AchRM1 receptor protein in the visual cortex were 248.00±33.31,455.17±42.40 and 396.17±47.57 in the normal control group,LIM model group and the LIM electroacupuncture group,with a similar pattern among the groups (both at P＜0.05).Conclusions A electroacupuncture stimmulation do not affect the myopic diopter and axial length in LIM model.The AchRM1 and AchRM1 receptor in the visual cortex up-regulate in LIM eyes,infering that electroacupuncture stimmulation can improve vision by decreasing the level of AchRM1 receptor in visual cortex in LIM eyes in guinea pigs.

Objective To investigate the antitumor therapeutic effect of combined therapy of magnetic induction heating by nano-magnetic particles, herpes simplex virus thymidine kinase gene(HSV-tk suicide gene) and internal radiation in mice bearing MCF-7 breast carcinoma. Methods The transfection reagents, plasmids heat shock protein-HSV-tk (pHSP-HSV-tk), ferroso-ferric oxide nano-magnetic fluid flow and 188Re-ganciclovir-bovine serum albumin-nanopaticles (GCV-BSA-NP) were prepared. The heating experiments in vivo were carried out using ferroso-ferric oxide nano-magnetic fluid flow. Sixty mice tumor models bearing MCF-7 breast carcinoma were established and randomly divided into six groups. Group A was the control group, B was gene transfection therapy group, C was hyperthermia group, D was gene transfection therapy combined with radionuclide brachytherapy group, E was gene therapy combined with hyperthermia group, and F was gene therapy, hyperthermia combined with radionuclide brachytherapy group. The tumor growth, tumor mass and histopathological changes were evaluated. The expression of HSV-tk in the groups of B, D, E and F was detected by RT-PCR. Poisson distribution and one-way analysis of variance (ANOVA) were used for statistical analysis by SPSS 10.0 software. Results In the animal heating experiments, the temperature of tumor increased up to 39.6 ℃, 43.2 ℃, and 48.1 ℃ quickly with different injected doses (2, 4 and 6 mg respectively) of nano-magnetic particles and maintained for 40 min. The temperature of tumor tissue reduced to 36.8 ℃, 37.5 ℃ and 37.8 ℃ in 10 min when alternating magnetic field (AMF) stopped. The tumor mass in Groups C ((452.50 ±30.29) mg), D ((240.98 ±35.32)mg), E((231.87 ±27.41) mg) and F ((141.55 ±23.78) mg) were much lower than that in Group A ((719.12±22.65) mg) (F=800.07, P＜0. 01), with the most significant treatment effect in Group F.The tumor mass in Group B((684.05 ±24.02) mg) was higher than that in Group D (t =32. 805, P ＜0. 05). Semi-quantitative RT-PCR analysis showed that the expression of HSV-tk in Groups B and D (0.33 ±0. 13 and 0. 46 ±0.12) was significantly different from that in Groups E and F (0.66 ±0.13 and 0.74 ±0. 11)(F = 21. 573, P ＜ 0.05). Conclusion Combined use of hyperthermia, gene therapy and radionuclide brachytherapy could effectively depress the growth of MCF-7 breast carcinoma, thus possessing treatment potential for this tumor.

373 adult cases with type Ⅱ diabetes mellitus were treated with, Shenqi Jiung Tang (SJT) Tablet and 108 cases with phenformin as control. The result showed that the symptoms were remarkably alleviated after treatment with SJT tablet.

Seventy-four patients aged 26-63 yr who had suffered cervicogenic headache for 3 months-21 yr were treated with puked radiofrequency applied to C2 dorsal root ganglion, which is located in the middle of the posterior side of lateral atlantoaxial joint. A trochar was introduced percutaneously under the guidance of X-ray aiming at the target point. As it was inserted through the deep fascia, the stylet was withdrawn and a 10 cm long 22 gauge curved blunt electrode was inserted into the trochar and advanced until the patients felt radiating pain from the point of puncture to occiput. Lateral radiograph was obtained to verify the placement of electrode. The tip of the electrode was usually located in front of spinal canal at the atlantoaxial joint level. Sensory stimulation was performed with 50 Hz and 0.1-0.5 V and the patients could feel radiating pain at occiput. Motor stimulation was performed with 2 Hz and 0.4-1.0 V and regular pulsation of the patient's muscle of occiput could occur. Pulsed radiofrequency was applied at 42 ℃7 for 240 s and was performed twice on each side. VAS scores and disturbances of daily activity, mood and sleep were recorded before operation and at 1 week and 1, 3, 6, 12 and 18 months after pulsed radiofrequency treatment. Complications and recurrence within 12 and 18 months were recorded. Follow-up was lost in 22 patients. VAS scores and disturbances of daily activity, mood and sleep significantly decreased after procedure. All of the patients responded without complications like infection, spinal cord and vertebral artery injury. Some patients had transient occipital neuralgia which was usually relieved within 24 h. The recurrence rate in 12 and 18 months after operation was 19% and 31% respectively.

From November 2003 to May 2010, intrathecal drug delivery system (IDDS) was implanted in 18 patients with chronic intractable pain. Analgesia was provided with morphine. Thirteen patients suffered from late stage cancer and 5 from diseases other than cancer. VAS score was used to measure intensity of pain in all 18patients. QLQ-C30 score was used to evaluate quality of life in cancer patients. The patients were followed up for 3-62 months in 5 non-cancer patients. All 13 cancer patients died at 57 days-10 months after operation. VAS scores were significantly decreased and QLQ-C30 scores increased by intrathecal administration of morphine. Side effects developed in all patients to some extent including nausea, vomiting, constipation, urinary retention, pruritus and over-sedation and vanished in a week. Intrathecal catheter was cut while being pulled out of the needle in 1 patient. Two patients developed low intracranial pressure after operation. Cerebrospinal fluid leakage occurred in 1 patient. One patient developed neuropathic pain in the posterolateral side of right leg.
