Herpes simplex virus(HSV)is a ubiquitous enveloped virus containing double-stranded DNA. HSV-1 infection can cause inflammation of the lips,conjunctivitis and encephalitis,HSV-2 infection can cause genital herpes at many ages,and both viruses can establish lifelong latent infection in the body. Membrane fusion triggered by the interaction of various HSV membrane proteins is an important way for viruses to enter host cells. This review introduced the conserved core fusion mechanism of HSV composed of four viral glycoproteins gD,gH,gL and gB by analyzing the structure of glycoproteins and their interaction modes. Since there is currently no HSV vaccine approved for marketing in the world,it is of great significance to study the mode of action of HSV and host cells for the development of vaccines

Objective To investigate the influence of passive smoking to pregnant woman's and fetus's health by the detection of biomarker. Methods A questionnaires about passive smoking made by ourselves were answered by 236 pregnant women including quantity and the number of year of smoking in the family and working places. At the same time pregnant woman's saliva, venous blood, urine and umbilical cord blood were collected. The sulphocyanate in their saliva was determined with pyridine-barbiturate method; the cotinine in venous blood, urine and umbilical cord blood were determined with barbiturate method. Results The content of sulphocyanate in saliva was different upon the quantity of passive smoking of pregnant women; there were significant differences had been seen among groups of passive smoking in cotinine in venous blood, urine and umbilical cord blood. Conclusion The contents of cotinine in venous blood, urine and umbilical cord blood are biomarkers of pregnant woman subjected to passive smoking, and passive smoking of pregnant woman will influence the health of pregnant woman and fetus.

Objective To assess the efficacy and safety of different dosages of oxycodone plus acetaminophen for treating acute pain after oral surgery,in order to provide a reasonable dosage of combination in clinic. Methods Randomized controlled trials ( RCTs ) on effect of combination of oxycodone plus acetaminophen on pain relief after oral operation were searched from the following data-bases:PubMed,EMbase,MEDLINE ( Ovid) ,the Cochrane Library,CNKI,and WANFANG from the date of their establishment to January 2015. The data of RCTs meeting the inclusive criteria were extracted according to Cochrane methods by two reviewers independently,and after the quality was evaluated and cross-checked,meta-analyses were conducted using RevMan 5.2 software. Results A total of 11 studies in 10 literatures involving 1 028 patients were included and were designated to 3 different dosage groups (5 mg/325 mg,10 mg/650 mg,10 mg/1 000 mg,respectively). The results of Meta-analyses showed that pain remission rate was significantly higher in the 3 different dosages of oxycodone plus acetaminophen groups than in the placebo group (RR5 mg/325 mg=3.35,95%CI [1.74,6.45],I2=38%,P=0.000 3;RR10 mg/650 mg=6.88,95%CI [4.00,11.83],I2=0%,P<0.000 01;RR10 mg/1 000 mg=4.94,95%CI [3.23,7.56],I2=81%,P=0.005). In additional,the RR of oxycodone 10 mg/acetaminophen 650 mg and placebo groups for pain remission rate was higher than that of the other 2 dosages groups,moreover,more studies were enrolled and its low heterogeneity led to high reliability. Usage rate of remedial painkillers was significally lower in oxycodone plus acetaminophen groups than in the placebo group (RR5mg/325mg=0.71,95%CI [0.60, 0.85],P<0.000 01;RR10mg/650mg=0.50,95%CI [0.41,0.61],P<0.000 01;RR10mg/1000mg=0.77,95%CI [0.66,0.90],P=0.001) ,In addition, the RRs of usage rate in oxycodone 10 mg/acetaminophen 650 mg and placebo groups were significantly lower than the other 2 dosages groups. Incidence rates of adverse effects were similar in the 3 different dosages groups and higher than that of the placebo group. However,the adverse events were generally described as mild to moderate in severity and rarely led to drug withdrawal according to all reports in the studies ( only one event ) . Conclusion The present study showed that combination of oxycodone plus acetaminophen can provide better analgesia in acute pain after oral surgery with high safety. In addition,combination of oxycodone 10 mg plus paracetamol 650 mg may be better for acute pain relief after oral surgery.

In order to study the effect of chronic noise exposure on auditory center, seven guinea pigs were .exposured to 105 dB A noise 8h daily for 45 d. Then the animals were killed by decapitation. The superior olive and inferior colliculus were taken immediately to make the samples of electron microscope. The mitochondria swelling, membrane rupture, cristae breaking, ballooning degeneration were found. The rough surfaced endoplasmic reticulum was swollen and expanded. The lysosome and secondary lysosome were increased. The cell interstitial edema and synaptic besicle decrease were observed. The nuclear chromatid was decreased and nucleolus was kept to the side. The laminae of neurilemma of nerve fibers were dissociated, swollen and broken. The results indicate that the ultrastructure, neural cells and fibers in the auditory center are damaged by chronic noise exposure and most of these damages are irreversible.

The changes of hair cells after acute radiation injury to cochlea were studied with scanning electron microscope in guinea pigs. Outer hair cell cilia were disordered, fused, and lost in the early stage after 40Gy ?-ray irradiation of the bullae of guinea pigs. From 15 to 30d after radiation, reconstruction of cilia besides early changes, and ball shape materials on the side of inner hair cells were found. The possible mechanism of these changes is also discussed

The effects of different doses of r-ray on cochlea are reported in this paper. Significant hearing loss and severe cochlea hair cells injury were found while radiation dose was more than 80 Gy. With 40 Gy to 60 Gy, slight hearing loss, but cochlea hair cells and support cells impairment were observed. With 20 Gy, no hearing loss and no hair cell damage were found. The results indicated that the damage increases with a dose of radiation and there is a delay effect of radiation on cochles.

Objective To sequence follicle stimulating hormone receptro (FSHR) promoter of the ovarian granulocyte and initially research the molecular mechanism of the poor ovarian response. Methods To study the relationship between FSHR promoter mutation of ovarian granulocyte and ovarian respone. The 263 bp DNA fragments before FSHR 5'initiation site in 70 cases of patients with poor ovarian respone and 88 cases of patients with ovarian normal respone who were in the cycle of IVF-ET were sequenced, Results There were 63 cases which occurred 29th site G → A point mutation in 158 women and the mutation rate was 40. 0%. Mutation rate [ 60. 0% ( 42/70 ) ] of 29th site G → A in group of poor ovarian respone was significantly higher(χ2 = 21. 450,P < 0. 01 ) than normal response group [ 23.9% ( 21/88 ) ]. There was no obviously variability ( t = 0. 457, P 0. 05 ) of basic FSH values between two groups [ G/G group was (7.2 ± 2. 3) U/L, G/A & A/A group was (7. 1±2. 0) U/L];there was obviously variability (t = 35. 81 ,P < 0. 05 ) in the number of follicles sinus between two groups ( G/G group was 14. 2±1.3, G/A & A/A group was 4. 5±0. 8 ) ;there was obviously variability ( t = 40. 35, P < 0. 05 ) in the number of ovum pick-up between two groups ( G/G group was 14. 0±1.2, G/A & A/A group was 4. 5±1.1 ) ;there was obviously variability (t =25. 80,P <0.05) of FE2-peak value between two groups [G/G group was (2 865±557) pmol/L, G/A & A/A group was (880±211 ) pmol/L] ;there was obviously variability (t =40. 22 ,P <0. 05) in the number of mature eggs ( G/G group was 13.6±1.2, G/A&A/Agroupwas4.3±0. 9).Conclusion The 29th site of FSHR promoter significantly affect the activity of FSHR promoter. Mutation of G→A can weaken promoter activity, so that ovarian granulocyte poor respone to FSH.

Objective To explore the clinicopathological features and diagnosis of adenoid cystic carci noma of the breast (ACCB).Methods Clinical data of 3 cases of ACCB were collected and followed up to observe the clinical pathological features.Immunohistochemistry was used to determine the immune phenotype.Results All the 3 cases were female,aging from 55 to 72 years old (61 years old as the average).The tumors were found in subareolar region well-circumscribed.ACCB was characterized by the presence of a dual cell population of luminal and basaloid cells arranged in cribriform and tubular-trabecular patterns.On immunohistochemical staining,the myoepithelial cells expressed SMA,CK5/6,P63,CD117 and the glandular epithelium cells were mostly positive for CK18,EMA,CK7,while no expression of ER,PR,HER-2,CD10 was observed.Conclusions ACCB is a rare neoplasm with a triple-negative,basal-like phenotype,but exhibits an indolent clinical behavior.The diagnosis can be worked out by evaluation of clinical characterstics,histological and immunohistochemical features.
