Objective: To investigate the late identification of newly reported HIV/AIDS cases in Wuxing District of Huzhou City, Zhejiang Province from 2012 to 2021, and analyze the influencing factors, so as to provide the basis for improving AIDS prevention and control measures and promoting early identification of HIV/AIDS cases. Methods: Data pertaining to demographics, CD4+T lymphocyte counts, transmission routes and identification routes among newly reported HIV/AIDS cases in Wuxing District from 2012 to 2021 were collected through the HIV/AIDS Comprehensive Control System of Chinese Disease Prevention and Control Information System. The proportions of late identification of cases with different characteristics were descriptively analyzed, and factors affecting late identification were identified using a multivariable logistic regression model. Results: Totally 627 HIV/AIDS cases were reported in Wuxing District from 2012 to 2021, including 555 males (88.52%), and had a mean age of (40.30±15.98) years. There were a total of 212 cases with late identification, and the annual average proportion was 33.81%. The proportions of late identification ranged from 51.85% in 2012 to 28.00% in 2021, with no significant changing trend (χ2trend=1.152, P=0.283). Multivariable logistic regression analysis showed that higher proportion of late identification was more likely seen in the registered cases in Wuxing District (OR=1.651, 95%CI: 1.140-2.393), cases at ages of 40 years and older at diagnosis (OR=1.719, 95%CI: 1.068-2.766), and cases identified by medical institutions (OR=1.809, 95%CI: 1.136-2.881). Conclusion HIV/AIDS cases registered in Wuxing District, aged 40 years and older, and identified by medical institutions have higher proportions of late identification in Wuxing District from 2012 to 2021.

Background and purpose:Nowadays, about therapy of laryngeal carcinoma, people are paying more and more widely attention to ifnding out how to improve quality of patients’ life besides radical surgery. For glottic laryngeal carcinoma which invading anterior commissure or bilateral vocal cord, we performed modiifed frontolateral partial laryngectomy or modiifed cricohyoidoepiglottopexy, and contrastive analyzed the therapeutic efifcacy of the two ways. Methods:Sixty cases patients of glottic laryngeal carcinoma who treated in Hunan Provincial Tumor Hospital during 2005 to 2010, which invaded the anterior commissure or bilateral vocal cord, were randomly attributed to two groups as A and B;30 patients of group A were underwent modiifed frontolateral partial laryngectomy and repaired with bilateral sternohyoid muscle lfap, 30 patients of group B were treated by modiifed cricohyoidoepiglottopexy. Follow-up time of each patient was 5 years postoperation and clinical data were retrospectively analyzed. Results:The 5-year survival rate was 86.7%in group A as well as 83.3%in group B, and there was no statistical difference between two groups (P=0.718). Pronunciation function:22 cases in group A and 21 cases in group B whose pronunciation function can be competent in the noisy environment, and can pronounce“a”and“i”vowel;8 cases in group A and 9 cases in group B can pronounce only a“ha”,“hi”sound, that couldn’t communicate with others in a noisy environment. There was no statistical difference in pronunciation function between the two groups (P=0.774). Incidence of deglutition disorder 4 weeks postoperation:group A was 0 (0/30), group B was 16.7%(5/30), and the difference between the two groups was statistically signiifcant (P=0.026);average time of extubation postoperation:group A was (10±2.3) d, group B was (20±4.6)d, and the difference between the two groups was statistically signiifcant (P=0.0000);recurrence rate of dyspnea after extubation:group A was 16.7%(5/30), group B was 0 (0/30), and there was statistically signiifcant difference between the two groups (P=0.026). Conclusion: For the glottic laryngeal carcinoma which invading anterior commissure or bilateral vocal cord, there was no statistical difference in 5-years survival rate and function of pronunciation between modified frontolateral partial laryngenctomy and modified cricohyoidoepiglottopexy postoperation. The former had less postoperative deglution disorder, earlier extubation time, and to some extent, alleviated the suffering of the patients, but part of these patients needed secondary surgery due to dyspnea which resulted by radioactive tissue adhesion after extubation. The latter had more serious deglution disorder postoperation, longer recovery time, and relatively longer time to extubating, showed no again dyspnea after extubation, and had more extensive adaptation disease. In a word, each way of operation has its advantage respectively.

Objective To evaluate of the clinical effect of triple arthrodesis and bone grafting combined with plat screw internal fixation for treatment of necrosis of talus. Methods The clinical data of 24 patients with necrosis of talus who were treated by triple arthrodesis and bone grafting combined with plat screw internal fixation from April 2011 to January 2015 in Xiangya Second Hospital of Central South Univer-sity were retrospectively analyzed. And the clinical effect were measured by AOFAS Ankle Hind-foot Scale System. Results The 24 patients were followed up for 26 months averagely (12~36 months). According to AOFAS Ankle Hind-foot Scale System, there were 4 cases of mod-erate and 20 cases of bad before treatment, and there were 18 cases of excellent, 4 cases of good, and 2 cases of moderate after the treat-ment. Conclusion It can achieve good clinical results in treatment of necrosis of talus through triple arthrodesis and bone grafting combined with plat screw internal fixation.

0.05),but the HPPT was dose-dependently increased in 25 and 50 mg?kg -1 groups(P0.05); on the contrary ,strychnine 0.5,0.75,1.0 ?g(it) decreased the HPPT of propofol-treated mice as doses increased(P0.05). CONCLUSION Propofol can induce antinociception in hot-plate test and acetic acid-induced writhing test of mice. Spinal glycine receptors may play a role in propofol's antinociceptive properties in hot-plate test of mice.

The 3T3-L1 preadipocytes were used as carriers in the investigation of total extract, n-butanol extract, CB-1 and CB-2 of Coreopsis tinctoria Nutt. on cell proliferation and differentiation. Three groups at different doses were set for each of the four extract regions of C. tinctoria Nutt., respectively. MTT assay was used to detect 3T3-L1cell proliferation by four extract regions of C. tinctoria Nutt. Oil Red O staining was used to analyze the formation and accumulation of cytoplasmic lipid during cell differentiation. The results showed that compared with the control group, there were significant inhibition on cell proliferation when thetotal extract of C. tinctoriaNutt. at 100 μg·mL-1, n-butanol extract at 0.5, 5, and 50 μg·mL-1, CB-1 and CB-2 at 50 μg·mL-1 (P< 0.01). N-butanol extract showed certain dose-dependent manner (r = -0.903). Oil Red O staining showed that compared with the control group, thetotal extract of C. tinctoria Nutt. at 1, 10, 100 μg·mL-1 can obviously inhibit cell differentiation, reduce the formation of cytoplasmic lipid (P< 0.01). N-butanol extract can inhibit cell differentiation in a dose-dependent manner (r= -0.779). CB-1 and CB-2 obviously inhibited cell differentiation at the concentration of 50 μg·mL-1 (P < 0.01). It was concluded that thetotal extract, n-butanol extract, CB-1 and CB-2 of C. tinctoria Nutt. can inhibit the proliferation and differentiation of 3T3-L1 preadipocytes and reduce the formation of cytoplasmic lipid.

OBJECTIVE: To review the clinical manifestations and management of nasal sinus mucoceles invaded the skull base and orbit. METHOD: Medical records for 30 patients of paranasal sinus mucoceles invaded the skull base and orbit were reviewed retrospectively. CT and MRI were important tools for diagnosing nasal sinus mucocele. The patients received endoscopic surgery to remove mucocele, some of them were operated auxiliary incision. Steroid therapies were given after the operations and routine examination with endoscopy were carried out during follow-up. RESULT: All cases were successfully performed surgery without complications after the surgeries, or the majority of symptoms. However, vision recovery was observed only in some patients. Recovery of vision depended on the timing of surgery and severity of initial visual loss. Delay treatment can seriously compromise the recovery of vision impairment. Moreover, the patients without light perception before surgery had poor visual recovery even when optic nerve decompressions were performed. CONCLUSION Endoscopic surgery has effect on nasal sinus mucocele with visual loss. Because visual recovery depends on prompt diagnosis and surgical intervention,a good understanding of the disease and prompt imaging studies are important.

Objective To establish a specific, sensitive and simple assay for the detection of Brugia malayi larva in Anopheles sinensis .Methods Using a new DNA purification technique (Microcon 100) and two pairs of oligonucleotide primers (p1, p2 and p3,p4) suitable for detecting B malayi in seven areas in our country, the mosquito vectors infected by B malayi were detected by polymerase chain reaction(PCR).Results This PCR method could amplify separately a 322 basepair(bp) and a 155 bp DNA fragment and detect as few as 1/64 of one L 1 in 1 mosquito,the detectable limit was nearly 4 pg DNA of filarial larvae, and it could also detect 1 infected mosquito with one L 3 of B malayi in pools of up to 200 mosquitoes. In contrast,no such specific 322 bp or 155 bp DNA band was detected in Dilofilaria immitis and normal mosquito.Conclusion This PCR techique established for supervision of mosquito vector in B malayi endemic areas is specific,sensitive,and simple.

OBJECTIVE: This article summarizes the matters warranting consideration in adult cochlear implants before and after operation with different deafness causes and investigates the impact of etiological variables that affect hearing and speech ability rehabilitation after cochlear implantation. METHOD: We retrospectively reviewed the preoperative data of 30 adults who have received cochlear implantation, switch on, and periodical post operative mapping. 'Nijmegen Cochlear Implant Questionnaire' was used for every patient during follow-up and test their hearing thresholds at one year after switched-on. The average score of every patient in the six aspects of questionnaire, along with the average hearing threshold, has been gathered. RESULT: The average hearing threshold of every patient is lower than 35 dBHL. The average score of 28 patients is more than or equal to 75 in the basic sound perception, advanced sound perception as well as self-esteem. The average score of 26 patients is more than or equal to 75 in capacity for action. Besides, as for sociability and speech ability, the average score of 22 patients is more than or equal to 75. CONCLUSION Auditory perception can be greatly improved regardless of deafness causes, on the premise that appropriate candidate is selected. The primary disease should be brought under control before and after the operation. The influence of various causes to the language ability rehabilitation largely depends on the development of the language center at deafness onset. Self-esteem and social identity can be significantly enhanced after cochlear implantation in adult patients, particularly those with acquired deafness.
