1.Research progress on herpes simplex virus membrane fusion protein interactions
Chinese Journal of Biologicals 2024;37(1):92-98
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 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.

Objective To prospectively study the dynamic variation of vascular endothelial growth factor (VEGF),the short-term efficiency and the tolerability of the esophageal cancer patients treated by radiotherapy combined with thalidomide.Methods The serum samples of 86 esophageal cancer patients were collected before,during and after the radiotherapy.The VEGF levels were assayed by enzyme-linked immunosorbent assay (ELISA).3 patients interrupted the treatment because of intolerance radiotherapy.Based on the changes of VEGF level,32 esophageal cancer cases whose VEGF levels increased or remained were assigned to the group to which thalidomide was given during the whole course of radiotherapy.The rest 51 patients whose VEGF level decreased received radiotherapy without thalidomide during the whole course.In addition,30 healthy cases were included in control group.Then the efficiency and safety of the introduction of thalidomide in radiotherapy were investigated. Results The VEGF levels of 86 esophageal cancer cases were significantly higher than the 30 healthy control cases ( t =5.07,P < 0.01 ),which were also correlated with the primary tumor size ( t =4.55,P < 0.01 ),lymph node metastasis ( t =7.50,P <0.01 ),histological type( F =3.40,P < 0.01 ) and clinical stage ( t =2.52,P < 0.0 l ).However,it was irrelevant to the lesion site,distant metastasis,X-ray pathologic type,gender or age ( P > 0.05).For the thalidomide involved group, the VEGF level after radiotherapy was significantly lower than during radiotherapy (t =2.37,P <0.05 ) with an effective rate of 71.88%.For the rest 51 cases without using thalidomide,the effective rate was 78.43% yet there was no significant difference between the VEGF levels during and after radiotherapy ( t =0.18,P > 0.05 ).62.50% patients reported symptoms of dizzy and burnout after using thalidomide,while this incidence was 15.69% for the rest patients (x2 =19.28,P =0.000).For the groups with or without thalidomide combination,the sleepiness incidences were 18.75%and 1.96%,respectively (x2 =5.168,P =0.023 ); the Ⅲ - Ⅳ grade esophagitis incidences were 12.50% and 11.76%,respectively (x2 =0.061,P =0.806) ; the Ⅱ - Ⅳ grade leukocyte decrease incidences were 6.25% and 9.80%,respectively (x2 =0.026,P =0.872) ; the Ⅲ - Ⅳ grade platelet descend incidences were 3.13% and 5.88%,respectively (x2 =0.002,P =0.965 ) ; the Ⅲ - Ⅳ grade nausea and vomiting incidences were 9.38% and 27.45%,respectively (x2 =2.913,P =0.088 ). No anaphylaxis was observed. Conclusions Thalidomide can decrease the VEGF expression level of esophageal cancer patients.Patients treated with thalidomide show good tolerance and compliance.
