AIM: To evaluate the effect of He-Ne laser combined with TDP irradiation in the treatment of herpes zoster ophthalmicus.METHODS: Totally 22 patients (22 eyes) with herpes zoster ophthalmicus were treated by He-Ne laser irradiation combined with TDP (Group A).Another 22 patients (22 eyes) with herpes zoster ophthalmicus (Group B) were treated by medication.The duration of the disease, the incidence of complications, and the time of pain relief were compared between the two groups.RESULTS: The cure rate of Group A was 91%, that of Group B was 73%, there was no significant difference between the two groups (x2=1.375, P>0.05).The average cure time of Group A was 8±2.22d, Group B was 12±1.88d, the difference between the two groups was statistically significant (t=5.22, P<0.05).The complication rate of Group A was 18%, Group B was 59%, the difference between the two groups was statistically significant (x2=6.86, P<0.05).The average pain relief time of Group A was 5±1.23d, Group B was 10±1.34d, the difference between the two groups was statistically significant (t=11.17, P<0.05).CONCLUSION: He-Ne laser combined with TDP irradiation can shorten the treatment time of herpes zoster ophthalmicus, shorten the course of disease, reduce the incidence of complications, relieve pain, with no significant effect on the cure rate of herpes zoster ophthalmicus.

Objective:To observe the effect of acupoint massage plus acupoint sticking therapy for the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery.Methods:A total of 120 patients undergoing nasal endoscopic surgery were included,and all patients were under trachea intubation and general anesthesia.The patients were randomized into an observation group and a control group,with 60 patients in each group.Patients in the control group received conventional anesthesia resuscitation,while patients in the observation group received acupoint massage plus acupoint sticking therapy on the basis of conventional anesthesia resuscitation.Changes in the heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed at three time points including the end of the surgery (TO),the removal of the tracheal tube (T1) and 10 min after the removal of the tracheal tube (T2).The awakening and tube removal time,choking cough and restlessness,and adverse reactions (dizziness,nausea and vomiting) in 24 h post-surgery period were compared.Results:At T1 and T2,the comparisons of HR,SBP and DBP between the two groups showed statistical significance (all P＜0.05).Intra-group comparisons showed that the HR,SBP and DBP of the control group at T1 and T2 were significant different from those at TO (all P＜0.05).There were significant differences in the awakening time and tube removal time between the two groups (both P＜0.05).The incidences of choking cough and restlessness were 8.3％ and 3.3％ respectively in the observation group,versus 53.3％ and 30.0％ in the control group,and the between-group comparisons showed statistical significance (both P＜0.05).The incidences of dizziness,nausea and vomiting in 24 h post-surgery period were 3.3％,5.0％ and 0.0％ respectively in the observation group,versus 43.3％,33.3％ and 25.0％ in the control group,and the between-group comparisons showed statistical significance (all P＜0.05).Conclusion:Acupoint massage plus acupoint sticking therapy can effectively regulate the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery,and maintain a stable internal environment.

Objective To establish a method for rapidly detecting the G-protein ?3 subunit (GNB3) 825 site single nucleotide polymorphism (SNP) and to analyse the relationship between GNB3 825 site gene SNP and obesity. Methods The real-time fluorescent PCR was employed to analyse the GNB3 825 site gene SNP of 420 samples from 21 provinces and the the frequencies of genotypes were compared with those detected by gene sequencing. GNB3 825 site genotype, body weight, body mass index (BMI) and fat content were examined from 207 subjects and the correlation between GNB3 825 site gene SNP and obesity was analysed. Results The result by real-time fluorescent PCR showed that the frequencies of 825T and 825C haploid were 46.90% and 53.10%, respectively, and the frequencies of 825TT, 825TC and 825CC genotype were 22.38%, 51.42% and 28.10%, respectively, with no other genotype detected, which was consistent with the result by gene sequencing. BMI and fat content were significantly higher in subjects with GNB3 825TT than in subjects with other genotypes. Body weight was much higher in subjects with GNB3 825TT genotype than in subjects with 825CC genotype, but not significantly different with 825CT genotype. Conclusion A new rapid method for the detection of GNB3 825 site SNP has been successfully established. There existed significant correlation between GNB3 825TT genotype and obesity.

Objective To investigate the changes and pathogenic significance of serum interleukin-12p70 (IL-12), intefferon-γ,(IFN-γ) and IL-4 in the course of hemorrhagic fever with renal syndrome(HFRS). Methods Twenty five eases were divided into mild group (14 eases) and severe group (11 cases) according to the severity of illness. Blood samples were collected in various stages(fever, hypotensian and oliguria,diuresis stage). Serum IL-12 and IFN-γ levels were determined by enzyme-linked immunoserbent assay(ELISA), IL-4 by radioimmunoassay (RIA), blood urea nitrogen (BUN) and platelet by automatic biochemical analyzer and blood analyzer. Results Serum IL-12 levels in mild and severe groups were significantly different during various stages of HFRS (F=5.765, P<0.01). The IL-12 level of both patient groups significantly increased(P<0.01) in fever[ (0.87±0.38), (1.08± 0.77)μg/L], hypotension and oliguria [ (0.77±0.21), (2.11±2.13)μg/L] ,and diuresis stage [ (1.42±1.10), (1.20±0.88)μg/L], compared with control group [(0.56±0.10)μg/L]. In various stages, IFN-γ levels of both case groups were respectively (8.04±13.05), (5.94±8.24), (15.95±18.05), (4.41±4.10), (1.09±1.24), (1.38±1.74), (1.12±1.26), (0.19±1.29)μg/L, and the difference was statistically significant compared with control [ (0.27±0.15)rig/L]. K,-4 levels did not change significantly in the stages(F=0.682, P0.05), while the ratios of IFN-γ and IL-4 contents in mild and severe cases were significantly higher than control [(0.36±0.26) μg/L] in fever[ (2.46±3.52), (16.92±22.77)p.g/L], hypotension and oliguria[(2.52±2.72), (1.77±2.06) μg/L],diuresis stage [(1.45±2.28), (2.32±3.98)μg/L], the difference had statically significant (P<0.05 or 0.01).The curve of IL-12 was similar to that of BUN, but was contrary to blood platelet count. Conclusions The elevated levels of IL-12 and IFN-γ, with the imbalance of Th1/Th2 might be the main cause of systemic inflammatoryresponse and involved in the pathogenesis of HFRS.

OBJECTIVETo discuss the changes of lymphocyte subsets in HCV children with different genotypes during treatment with pegylated interferon alfa-2b and ribavirin.

METHODSThe genotype of 45 HCV infected children were identified by real time PCR. The lymphocyte subsets were dynamically detected by BD FACSCalibur flow cytometer with four color MultiTEST IMK Kit during the treatment.

RESULTSFor the children with 1b genotype, after 24 weeks, the CD4+ T cells were higher than pre-treatment (P < 0.05). For the children with 2a genotype, after 12 weeks and after 24 weeks, the CD3+ T cells and CD4+ T cells significantly increased while the NK cells decreased than pre-treatment (P < 0.05).

CONCLUSIONSThe lymphocyte subsets of HCV children with 2a genotype were different from 1b genotype during trentment with pegylated interferon alfa-2b and ribavirin.

OBJECTIVETo study the effects of exogenous ER beta on the growth of breast cancer MCF-7 cells under different treatment.

METHODSAn eukaryotic expression vector containing 1.6 kb of human entire coding sequence of ER beta (pCDNA3-ER beta) was transfected into human breast cancer MCF-7 cells using lipofectamine 2000. The biological activity of ER beta was detected with the luciferase reporter containing estrogen responsive element (ERE) and the expression of ER beta protein by Western blot. The growth properties of MCF-7, pCDNA 3-transfected MCF-7 and pCDNA 3-ER beta-transfected MCF-7 cells under different treatment, including E2 (17beta-estradiol) and 4-OHT (4-hydroxytamoxifen), were observed.

RESULTSA stronger activation of the reporter by ER beta in the presence of E2 was observed in the pCDNA 3-ER beta-transfected MCF-7 cells than in the pCDNA 3-transfected MCF-7 and in MCF-7 cells. Western blot analysis showed that the protein level of ER beta in the pCDNA 3-ER beta-transfected MCF-7 cells was markedly increased. Exogenous ER beta expression did not change the growth properties and the morphology of MCF-7 cells under normal condition. The pCDNA 3-ER beta-transfected MCF-7 cells proliferated at the same rate as naive cells in the presence of 4-OHT, whereas a strong inhibition of the proliferation of the pCDNA 3-ER beta-transfected MCF-7 cells in the presence of E2 was observed.

CONCLUSIONExogenous ER beta expression does not increase the resistance to 4-OHT, and a strong inhibition of the proliferation may occur in the presence of E2.

OBJECTIVETo observe the effect of ginsenoside Rg1 on behavior and hippocampal amino acids in depressive-like rats.

METHODSD rats were randomly divided into 5 groups: control, model, fluxetine, low dose ginsenoside Rg1 and high dose of ginsenoside Rg1. The chronic unpredictable mild stress (CUMS) was performed to induce depressive-like animal model. Fluxetine group was orally given fluxetine in dose of 10 mg x kg(-1) for 21 days, low dose ginsenoside Rg1 group was orally given ginsenoside Rg1 in dose of 20 mg x kg(-1) for 21 days, high dose ginsenoside Rg1 group was orally given ginsenoside Rg1 in dose of 40 mg x kg(-1) for 21 days. The control and model group was orally given saline for 21 days. The sucrose consumption was detected before and after the CUMS procedure. The horizontal and vertical activities of rats were determined by open-field test. HPLC was adopted to detect the contents of amino acids in hippocampus.

RESULTThe sucrose consumption, horizontal and vertical activities in CUMS rats were decreased compared with those in control group. Compared with control group, the contents of glutamate (Glu) and aspartate (Asp) in hippocampus of CUMS group were increased, while the gamma amino butyric acid (GABA) and taurine (Tau) were decreased. Ginsenoside Rg1 treatment significantly increased the CUMS-induced decrease in sucrose consumption, horizontal and vertical activities. Administrated with ginsenoside Rg1 also decreased Glu and Asp and increased the GABA and Tau in hippocampus in a dose dependent manner.

CONCLUSIONGinsenoside Rg1 could alleviate the behavior changes of depressive-like rats, which might be related to regulate the levels of amino acids in hippocampus during CUMS and prevent the neuro-toxicity of excitatory amino acids.

Estrogen receptor alpha (ERalpha) has been a primary target of treatment as well as a prognostic indicator for breast cancer. The level of human X-box binding protein 1 (XBP-1) mRNA was related with that of ERalpha in breast tumors and was over-expressed in some breast tumors. These previous studies suggested that XBP-1 may interact with ERalpha. XBP-1 has two isoforms, XBP-1S and XBP-1U, as the result of unique splicing. GST pull-down assay showed that both XBP-1S and XBP-1U bound to ERalpha in vitro. The binding of XBP-1S to ERalpha was stronger than that of XBP-1U to ERalpha. Co-immunoprecipitation revealed that the binding was in a ligand-independent manner. XBP-1S and XBP-1U interacted with the region of ERalpha that contains a DNA-binding domain. The ERalpha-interacting regions on XBP-1S and XBP-1U have been mapped to two regions, the N-terminal basic region leucine zipper domain (bzip) and the C-terminal activation domain. These findings suggest that XBP-1S and XBP-1U may participate in ERalpha signaling pathway through the mediation of ERalpha.

OBJECTIVETo investigate the clinicopathologic feature, immunophenotype and differential diagnosis of cutaneous Rosai-Dorfman disease (CRDD).

METHODSClinical manifestation, morphologic features and immunohistochemical staining were studied in 8 cases of CRDD.

RESULTSAll 8 patients presented with multiple papules, nodules and/or coalescent patches or plaques distributing over the extremities or trunk, without lymphadenopathy or other systemic abnormalities. Microscopically, the lesions were located intradermally and/or subcutaneously. CRDD was characterized by the presence of S-100 positive histiocytic cells exhibiting emperipolesis, accompanying with infiltration of mixed inflammatory cells. Fibrosis, somewhere in vague storiform pattern due to stromal responses, with distribution of individual neutrophil microabscess was seen in cases with a long course of illness. Dilated vascular spaces in dermis containing numerous large typical histiocytes were seen in 2 cases.

CONCLUSIONSCRDD is a benign, persistent proliferative disease of histiocytes. Systemic involvement is rare, outcome favorable. It should be differentiated from other types of histiocytosis, dermatofibrosarcoma protuberans, xanthoma and lymphoproliferative disorders. Immunohistochemical staining for S-100 protein and CD68 is helpful in making a correct diagnosis.
