Visual function, intraocular pressure and ocular blood flow were compared.?RESULTS:1, 2, 3 and 4wk after treatment, observation group during the day intraocular pressure, night intraocular pressure were significantly lower than that in control group, vision levels (0. 27±0. 03, 0. 36±0. 06, 0. 44± 0. 06, 0. 63 ± 0. 13 ) were significantly higher than that in control group; observation group peak systolic velocity (14. 41± 1. 73) cm/s, end diastolic velocity (4. 18 ± 0. 67) cm/s were significantly higher than that in control group;vascular resistance index ( 0. 58 ± 0. 07 ) was significantly lower than that in control group.? CONCLUSlON: Latanoprost combined with timolol treatment can reduce intraocular pressure, increase blood flow of central retinal artery, reduce vascular resistance, improve visual acuity.

OBJECTIVE: To investigate the influence of aluminum hydroxide adjuvant on a murine model of allergic rhinitis (AR) and to confirm an appropriate method of establishing a mouse model of AR. METHOD: Establishing two types of BALB/c mice models of AR, one was identified as Local group which was characterized through intranasal sensitization and challenge using ovalbumin (OVA), and the other Systemic group which was made by intraperitoneal sensitization with OVA plus aluminum hydroxide and intranasal challenge through OVA. Then the numbers of sneezing and nasal rubbing were counted after the last challenge and the eosinophils in the nasal mucosa of mice models were observed and counted though Luna stain. Furthermore, morphological hyperplasia was examined in intraepithelial goblet cells and submucosal glands with HE stain. In addition, interlukin (IL) -4, IL-5, OVA specific IgE (sIgE) and interferon (IFN)-gamma in nasal lavage fluid (NLF) and serum of mice were examined u sing enzyme linked immunosorbent assay (ELISA). RESULT: The counts of sneezing and nasal rubbing in local group were more than those in systemic group and eosinophilia in the nasal mucosa of former group was greater than that in the latter one. Morphological hyperplasia was stronger in intraepithelial goblet cells and submucosal glands in local group compared with that in systemic group. Furthermore, the contents of IL-4, IL-5 and sIgE increased in the NLF and serum of mice of local group compared to those of systemic one. However, the production of IFN-gamma of mice in local group decreased when compared with that in Systemic group. CONCLUSION OVA plus aluminum hydroxide adjuvant may promote Th1 type immune response as well as Th2 response. OVA intranasal sensitization and challenge locally is an appropriate way in the establishment of AR mice models.

AIM: To evaluate the therapeutic efficacy and safety of heavy silicone oil (HSO), Densiron 68, was used as internal tamponade to treat complex vitreoretinopathy.METHODS: A retrospective study of 30 patients (30 eyes) who underwent vitrectomy and HSO tamponade for complex retinal detachment between January 2015 and January 2016.The best corrected visual acuity (BCVA), intraocular pressure (IOP), retinal reattachment and complications after surgery were observed.RESULTS: There were statistical significances in both the BCVA difference between pre-operation and HSO tamponade, and the BCVA difference between pre-operation and the removal of HSO for 3mo (z=-2.198, P=0.028;z=-2.682, P=0.007).The average intraocular pressure of HSO tamponade group was 20.233±8.007mmHg, and the average intraocular pressure of pre-operation group was 16.067±4.025mmHg, showing significant difference(t=-2.913, P=0.005).Between the pre-operation group and the HSO removed group 14.933±3.423mmHg, there was no significant statistical difference in the analysis of IOP (t=2.635, P=0.430).Anatomical success was achieved in 90% of cases after the removal of HSO.Most common complications were cataract formation and oil emulsification.CONCLUSION: Densiron-68 is a safe and effective tamponade material for the treatment of complex vitreoretinopathy.However, most common complications are cataract formation and oil emulsification.So clinicians should strictly handle indications and usage during the clinical applications.

Circulating tumor cells(CTCs)are essential for establishing recurrence and metastasis in malignant tumors.Detecting CTCs can help for early detection of the cancer metastases and recurrences,and also can help for evaluating prognostic and guiding treatment.CTCs detection technique mainly include screening and separation technology which contains immune magnetic separation technology and reverse transcriptasepolymerase chain reaction and so on.With the development of technique,there is a new technique named ctcchip contains both screening and separation functions.

Objective To study the primiparas' sexual problems after delivery and the effect of in-dividualized nursing interventions on improvement of these problems in order to provide theoretic base-ment for sexual health education after delivery. Methods 248 primiparas after delivery in women's hos-pital were randomly divided into the intervention group and the control group with 124 cases in each group. All of them received self- designed questionnaires about sexual problems one year before pregnancy. The primiparas in two groups all receives routine care. Besides, the intervention group was given sexual health manual and received one-to-one individualized nursing intervention on sexual life after delivery according to their own conditions. The two groups were all received countercheck during 4 to 6 months after delivery and the results underwent X2 test. Results There was no significant difference between the sexual prob-lems one year before pregnancy for the two groups. But when calling back during 4 to 6 months after deliv-ery, compared with the control group, the intervention group had less sexual problems. Conclusions It is necessary to strengthen sexual health education in order to improve the sexual problems after delivery. Indi-vidualized nursing interventions can not only fulfill the sexual health demands of different primiparas after delivery, but also guarantee the women's privacy and safety.

Objective: To investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

Objective To investigate the significance of antibody to Ro-52 in patients with autoim-mune liver disease(AILD). Methods One hundred and fifteen patients with abnormal liver functions, who had anti-Ro-52 detection by immunological blotting, were reviewed retrospectively. According to types of AILD, the clinical features were compared between patients with and without anti-Ro-52, respectively, κ test of concordance was used to provide a chance-corrected valve for immune-serological results. Results The rates of anti-Ro-52 in autoimmune hepatitis( AIH), primary sclerosing cholangitis(PBC) and AIH/PBC o-verlap syndrome groups were 32.43%, 24.56% and 33.33%, respectively, there were no significant differ-enees among three groups ( x2 = 0. 949, P >0. 05). The rate of anti-soluble hver antigen/liver-pancreas ( an-ti-SLA/LP) in AIH patients with anti-Ro-52 (58.33%) was higher than AIH patients without anti-Ro-52 ( 16.00% ,P < 0.05 ). The rate of anti-SLA/LP in AIH/PBC overlap syndrome patients with anti-Ro-52 (85.71%) was also higher than that of control group (28.57% ,P <0.05). Anti-Ro-52 and anti-SLA/LP had concordance according to κ test( κ >0.40, P <0.05). The average level of IgG in AIH/PBC overlap syndrome patients with anti-Ro-52 was higher than patients without anti-Ro-52 ( t = 2. 508, P < 0.05 ). Conclusion The rates of anti-Ro-52 in AIH, PBC and AIH/PBC overlap syndrome were of no significant differences. Anti-Ro-52 may have correlation with anti-SLA/LP. AIH/PBC overlap syndrome patients with anti-Ro-52 shewed higher IgG level than patients without anti-Ro-52.

Objective: To observe the effectiveness and safety of electroacupuncture (EA) plus Luohua Anshen oral liquid for patients with perimenopausal insomnia. Methods: A total of 66 participants who met the inclusion criteria were enrolled in the randomized controlled trial and allocated to a treatment group and a control group at a ratio of 1:1, with 33 cases in each group. Both groups were given Luohua Anshen oral liquid as a basic treatment. The treatment group was additionally given EA every other day, three times a week. Both groups were treated for four weeks and a four-week follow-up was conducted. The scores of Pittsburgh sleep quality index (PSQI), Kupperman index (KI) and traditional Chinese medicine sleep syndrome scale (TCMSSS) were recorded at pre- and post-treatment, and at the follow-up. Meanwhile, adverse effects were monitored and recorded. Results: After four-week treatment, the global scores of PSQI, KI and TCMSSS in both groups declined significantly (all P<0.05), and the decreases in the treatment group were more significant than those in the control group (allP<0.05). The global scores of PSQI, KI and TCMSSS in both groups at the follow-up visit were significantly different from the corresponding baseline (allP<0.05), while insignificantly different from those assessed at post-treatment (allP>0.05). The total effective rate was 93.9％ in the treatment group, significantly higher than 72.2％ in the control group (P<0.05). No significant adverse event was reported in this trial excepted one patient experienced slight dizziness in the first acupuncture treatment. Conclusion: EA plus Luohua Anshen oral liquid is safe for perimenopausal insomnia with satisfactory short- and long-term effectiveness, and it shows certain advantage compared with using Luohua Anshen oral liquid alone.

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

AIM: To investigate the effects of prenatal stress (PS) on neurons and neuronal ultrastructure of hippocampus in offspring rats, and to explore the role of the overproduction of oxidants. METHODS: One month male offspring rats were obtained to observe the neuronal number, neuronal ultrastructure and the number of nNOS -positive cell in hippocampus. RESULTS: The neuronal number of CA1 and CA4 subregions in late gestation stress (LS) offspring decreases significantly. The neuronal ultrastructure of CA1 subregion in MS (stress in 7-13 days of gestation) and LS offspring appeared bulgy mitochondria, unclear membrane and irregular electron density. Lipofuscin pigments increased; The number of nNOS-positive cell in CA1, CA2, CA3 subregions and DG of MS group and the whole hippocampus of LS group increased significantly. CONCLUSION: PS damaged the neurons and neuronal ultrastructure of hippocampus of offspring rats. The damages were associated with the overproduction of oxidants.
