Objective To investigate the infection of human papilloma virus(HPV) and expression of serum squamous cell antigen (SCCAg) in the follow - up of 120 cervical squamous carcinoma patients who had received operation or operation combined with radiotherapy or only radiotherapy. Methods 120 cases of therapical cervical squamous carcinoma patients were detected HPV - DNA by HC - Ⅱ and serum SCCAg using immunohistochemical method. Results The positive rate of HPV - DNA and serum SCCAg was 49.17% and 17.50% , with a significant difference between them( P 0.05 ). Conclusion HPV - DNA test with HC - Ⅱ for follow - up of cervical squamous carcinoma patients was feasible. It was more sensitive than serum SCCAg. But it suggested that high risk type HPV -DNA test combined with serum SCCAg may be the independent prognostic factors.

OBJECTIVETo promote development and utilization of Ophiocordyceps gracilis in xinjiang and provide basic data for researching and sustainable developing medicine fungus related to O. gracilis.

METHODA white strain SFYT002 isolated from the sclerotium of O. gracilis in Xinjiang was researched by morphological observation, ITS and 18SrDNA sequencing. The ITS and 18SrDNA sequences of the strain were determined, BLAST was compared with the other sequences of Tolypocladium in GenBank. The phylogenetic trees of ITS and 18SrDNA sequences were analyzed in Tolypocladium. In addition, the filter paper method was used to study the antibacterial effects.

RESULTThe main morphological characters of this strain were white cotton-like colonies, phialide with inflated base, drastically sharping with partially bending tips, small and transparent budding spores with being always assemble to spearhead and globular, subglobular or ellipse conidiospores. The phylogenetic trees of ITS and 18SrDNA sequences were constructed and analyzed in Tolypocladium. It was resulted that Tolypocladium was confirmed to be monophyletic, and the strain SFYT002 was the same as the systematic position of others of T. inflatum. Meanwhile, the antibacterial test was performed against the 4 common pathogenic bacteria. It was showed that both fermentation and its extracts of different polar from this strain possessed good anti-bacteria capacities.

Objective To evaluate the therapeutic efficacy of hook plate and fascia lata graft in management of chronic acromioclavicular joint dislocation.Methods From May 2012 to March 2014,a total of 16 cases of chronic acromioclavicular joint dislocation (Rockwood type Ⅲ) were treated with hook plate and fascia lata graft.They were 10 men and 6 women,from 19 to 57 years of age (mean,34.7 years).Seven cases were at the left side and 9 at the right side.All injuries resulted from direct violence.The time from injury to surgery ranged from 8 to 54 weeks (mean,12.4 weeks).At the final follow-ups,the shoulder function was assessed using the Quick Version of the Disabilities of the Arm,Shoulder and Hand Score (DASH) and visual analogue scale (VAS),and the efficacy using Karlsson's evaluation system.Results All surgical wounds primarily healed.The dislocation of acromioclavicular joint was corrected,without any vascular or neural damage.The patients were followed up for an average of 12 months (from 6 to 18 months).No plate breakage,screw loosening or redislocation was observed.The DASH and VAS scores of the shoulder at the final follow-ups (25.42 ± 8.34 and 2.22 ± 1.70,respectively) were significantly improved,compared with the preoperative ones (43.72 ± 12.35 and 6.33 ± 1.37,respectively) (P ＜ 0.05).According to the Karlsson's criteria,10 cases were excellent,4 good and 2 moderate.Conclusion In management of Rockwood type Ⅲ chronic acromioclavicular joint dislocation,hook plate and fascia lata graft can restore dynamic balance and stability of the acromioclavicular joint,resulting in solid fixation,early joint motion and limited complications.

BACKGROUND:Rena gel and expansive sponge are two kinds of nasal packing materials, but there is stil a lack of comprehensive analysis on their filing effects.
OBJECTIVE:To compare the therapeutic efficacy of Rena gel and expansive sponge on nasal hemorrhage and postoperative nasal packing as wel as adverse reactions.
METHODS: A computer-based search of CBM, PubMed, EMBASE, Cochrane Library was performed for articles addressing randomized controled trials of Rena gel and expansive sponge as filing materials. The keywords were “Rena gel, randomized controled, expansive sponge” in Chinese and English, respectively. Then, aching feeling during filing and removal, sweling pain, bleeding, and bleeding control were compared and analyzed through a Meta-analysis.
RESULTS AND CONCLUSION:There were four randomized controled trials, involving 115 patients. The severity of pain was higher in the expansive sponge group than the Rena gel group when the filing materials were placed or removed (P < 0.05). However, there was no difference in the severity of pain between the two groups at 6 hours of filing (P > 0.05). The severity of sweling pain was higher in the expansive sponge group than the Rena gel group at 1 and 6 hours after filing (P < 0.05). When the filing materials were removed, the expansive group showed more severe bleeding than the Rena gel group (P < 0.05). No differences in the bleeding when filing and bleeding control were found between the two groups (P> 0.05). In addition, it was more difficult to fil or remove the expansive sponge from the nasal cavity (P < 0.05). These findings indicate that the Rena gel is superior to the expansive sponge in terms of pain, sweling pain, and bleeding when filing or removing the materials. But there is no difference in bleeding control between the two kinds of filing materials.

OBJECTIVE To investigate DNA hypermethylation of human 8-hydroxyguanine glycosy-lase(hOGG1 )gene and and the level of oxidative stress and DNA oxidative damage relations with arse-nic poisoning.METHODS In ende mic coal-pollution-borne arsenism area,Xinren county,Guizhou Province,according to the diagnostic criteria of ende mic arsenism(WS /T21 1 -2001 ),207 people with ende mic arsenism were selected and divided into four groups(The arsenic exposure group:46 cases, mild arsenism group:46 cases,moderate arsenism group:60 cases and severe arsenism group:55 cases).64 residents were selected as controls in a village about 12 km away fro m the ende mic arsenism area.With the informed consent principle,peripheral blood of all respondents was collected in order to analyze DNA methylation.Methylation-specific poly merase chain reaction were respectively performed to analyze hOGG1 Hypermethylation in arsenism respondents.Che mical methods were performed on the activity of super oxide dis mutase (SOD)and glutathione peroxidase (GSH-Px),while the contents of malondialdehyde (MDA)in the blood of patients were measured,and the contents of 8-hydroxy-2′-deox-yguanine(8-OHdG)urine of patients were measured and analysed.On the basis of methylation status are divided into hOGG1 gene methylation group (34 cases)and hOGG1 gene no methylation group (237cases).Analysis was performd on hOGG1 gene DNA methylation and the relationship between oxi-dative stress and arsenic poisoning.RESULTS The positive rates of hypermethylation of hOGG1 were associated with the degree of arsenic poisonin (co mpared with control group,χ2 =23.916,P <0.05, Co mpared with the Ende mic area normal group,χ2 =12.039,P <0.05 ).Co mparing with negative group,SOD〔(85 ±25)kU·L -1 〕,GSH-Px〔(70 ±26)kU·L -1 〕activity and 8-OHdG 〔(22.5 ±6.8)μg·L -1 〕contents were lower〔(1 18 ±41 )kU·L -1 ,(171 ±56)kU·L -1 ,(28.4 ±6.5)μg·L -1 ,P <0.05)〕in positive group.There was no significant difference between the MDA content(P>0.05).CONCLUSION Coal arsenic exposure can cause hOGG1 gene high methylation and oxidation and anti-oxidation system imbalance,causing DNA oxidative damage,it is one of the reasons to pro mote the develop ment of arsenic poisoning occurred.
