Objective:To comprehensively evaluate the clinical efficacy and safety of pulse radiofrequency therapy for knee osteoarthritis (KOA) with cardiovascular disease (CVD).Methods:A total of 132 patients with knee osteoarthritis (KOA) and cardiovascular disease (CVD) admitted to the First Affiliated Hospital of Xi′an Jiaotong University from March 2022 to February 2024 were randomly divided into two groups using a random number table method. Group A (65 cases) received ultrasound-guided pulse radiofrequency treatment of the hidden nerve, while group B (67 cases) received oral etoposide tablets and intra-articular injection of sodium hyaluronate. Basic data such as age, gender, height, weight, body mass index (BMI), knee joint function grading (K-L grading), and distribution of cardiovascular disease types were recorded between the two groups. The degree of knee joint pain [Visual Analog Scale (VAS) score] and Knee Joint Function Score (OKS), Athens Insomnia Scale (AIS) scores and incidence of complications. were compared between the two groups at 1 week, 1 month, 3 months, and 6 months after treatment.Results:The VAS score of group A showed a slow decreasing trend from 1 week to 6 months after treatment. The VAS score of group B decreased to the lowest level one week after treatment and gradually increased within 6 months after treatment. The VAS scores of both groups improved after 1 week of treatment and at 1, 3, and 6 months of treatment compared to preoperative levels ( F=703.955, P<0.001), and the degree of postoperative pain improvement in the group A was better than that in the group B ( F=106.575, P<0.001). The OKS of both groups decreased significantly after 1 week of treatment and at 1, 3, and 6 months of treatment, and the time effect was statistically significant ( F=2 233.447, P<0.001). The OKS of the group A was lower than that of group B after 1 week of treatment and at 1, 3, and 6 months of treatment, and the difference was statistically significant ( F=141.214, P<0.001). The AIS scores improved significantly after 6 months of treatment compared to preoperative levels ( F=1 044.424, P<0.001), and the group A had better AIS scores than the group B at 1, 3, and 6 months of treatment, with statistically significant differences ( F=124.864, P<0.001). There was no statistically significant difference in postoperative complications between the two groups ( P>0.05). Conclusions:Ultrasound guided pulsed radiofrequency treatment of KOA with CVD can significantly alleviate postoperative pain, improve joint mobility and sleep quality, and is more effective than traditional conservative treatment of oral etoposide tablets combined with intra-articular injection of sodium hyaluronate.

Objective To investigate the species,density and distribution of the overwintering adult mosquitoes in Taibaihu District,Jining City. Methods The overwintering adult mosquitoes were monitored by visual observation in Taibaihu District, Jining City from December 2015 to March 2016. The mosquitoes were collected and dissected to observe the body fat accumula?tion and ovarian development situation. Results Totally 1 677 mosquitoes were captured and all of them were Culex pipiens pal?lens. The highest positive rate of overwintering mosquitoes was in sweet potato cellars and greenhouses,with the positive rates of mosquitoes of 98.25%(56/57)and 81.36%(48/59)respectively. The accumulation of the fat body in the female mosquitoes plummeted from late February,and disappeared in middle March. Conclusions The adults of Culex pipiens pallens can over?winter in Taibaihu District,Jining City,and locate in sweet potato cellars and greenhouses mainly. The control work of adult mosquitoes should be strengthened in the overwintering period.

ObjectiveTo determine thallium in whole blood by atomic absorption detection method, and to investigate the eliminating effect of hemoperfusion (HP) for thallium in blood.Methods The blood of Beagle dogs which had not exposed to thallium before were obtained for preparation of thallium nitrate (TlNO3)-containing solution in three concentrations according to the conversion formula based on animal weight and volume of blood. HP was performed in the simulated in vivo environment. The content of TlNO3 in blood of the next group was determined on the amount of TlNO3 for the last HP of the former dose group. Thallium quantity in different samples was measured with atomic absorption spectrometer blood samples before and after HP. Finally, the thallium concentration in blood was analyzed statistically.Results Thallium concentrations showed a good linear relationship in the range of 0-200μg/L (r = 0.998 4). The intra-day precision (RSD) was lower than 4.913%, the intra-day recovery rate was 96.2%-111.9%; the inter-day precision (RSD) was lower than 7.502%, the inter-day recovery rate was 89.6%-105.2%. The concentration of thallium in blood was significantly reduced after HP per time in high, middle, and low dose groups [(453.43±27.80) mg/L to (56.09±14.44) mg/L in high dose group,F = 8.820,P = 0.003;(64.51±13.60) mg/L to (3.19±0.23) mg/L in middle dose group,F = 36.312,P = 0.000; (5.40±0.98) mg/L to (0.38±0.25) mg/L in low dose group,F = 46.240,P = 0.000]. The adsorption rate of four times of HP in high, middle and low dose group were (87.63±2.48)%, (95.06±1.54)% and (92.76±4.87)%, respectively, without significant difference (F = 4.231,P = 0.070 ).Conclusions The method for measuring thallium was established, and it shows a very stable, simple, sensitive for determination of thallium. HP can effectively remove thallium from blood. Thallium concentration can be reduced by 90% after four times of HP. HP is also effective even when thallium concentration is not high.

OBJECTIVEThis study was to evaluate the effects of prevention and control regarding programs on typhoid fever and paratyphoid fever, in Guizhou province, from 2007 to 2012, to provide evidence for the improvement of related programs.

METHODSData on typhoid fever and paratyphoid including information on epidemics, individual, cases, measures for prevention and control programs taken and relative government documents were collected and analyzed in Guizhou province, from 2007 to 2012. Information related to the average annual incidence, nature of outbreaks, time span before confirmed diagnosis was made, unit which carried the case report, proportion of laboratory confirmed diagnosed cases and case-management were compared between 2007-2009 and 2010-2012 descriptively while chi-square test with Excel and EpiInfo software were used for data analysis.

RESULTSIn the period of 2007-2009, a total of 5 978 typhoid fever and paratyphoid fever cases were reported in Guizhou province with the average yearly incidence as 5.29/100 000. In the period of 2010-2012, 2 765 cases were reported with the average yearly incidence as 2.57/100 000. When compared to the former, data from the latter period showed that the average yearly incidence had declined 51.31% in all the prefectures. There were still some outbreaks appeared but the total number of cases involved reduced 87.50%. The time span before the confirmation of diagnosis became shorter but the difference was not statistically significant (χ² = 0.08, P = 0.99). Number of cases reported by hospitals at county or above had 11.51% of increase while those cases reported at the township hospitals or below decreased for 61.47% . The proportion of laboratory diagnosed cases increased 23.63%. Rates of timeliness on cards being filled in, input and audited showed increase of 8.44%, 6.76% and 2.40% respectively.

CONCLUSIONSuccessful measures for prevention and control on typhoid fever and paratyphoid fever had been remarkably taken in Guizhou province, but the potential risk of outbreaks still existed in some areas, suggesting that health education and surveillance programs including laboratory diagnosis, should be strengthened.

OBJECTIVETo examine the flora samples from the tongue dorsum of the atrophic glossitis group and to discuss the relationship so as to provide a thinking pattern for therapy and a clue for deeper research.

METHODSTo collect personal information on 60 cases of atrophic glossitis and 40 cases of volunteers as control. The main items include general status, oral examination, salivary flow rate, pH value and bacteria test. All data were analyzed statistically.

RESULTS1) Among the 60 cases, 75.00% were female patients. Glosso-pain, dry mouth and taste loss were the most common symptoms. 2) In regard to the pathogenic factors, the systematic diseases were often visible, i.e. gastritis, coronary disease and anemia. 3) Oral hygiene of the patients was worse than that of the control group, the saliva flow rate and pH value were lower than that of the control. 4)The statistic analysis showed that the quantity of some bacteria of tongue dorsum and their detectable rate were different between the glossitis group and the control one, between the patients with atrophic glossitis who also suffered from different systematic diseases and the control group, and between the complete type and the partial type. These bacteria included Streptococcus sanguis, Stomatococcus, Staphylococcus aureus, Saccharomyces, etc.

CONCLUSIONAtrophic glossitis is the consequence co-affected by host, circumstances of oral cavity and bacteria. The tangible relationship between atrophic glossitis and micro-ecological changes on glossal dorsum has not been confirmed yet, however, flora change on dorsum may have relations with occurrence, and development of the disease.
