ABSTRACT
OBJECTIVE@#To study the predictive value of procalcitonin as a serum biomarker in diagnosis of late periprosthetic joint infection(PJI) for providing theoretical reference basis for diagnosis of PJI.@*METHODS@#A total of 77 cases were retrospective included from January 2015 to December 2017 for revision of total hip arthroplasty and total knee arthroplasty, according to the diagnostic criteria of Musculoskeletal Infection Society(MISI). All cases were divided into infection group and non-infection group. Infection group included 21 cases, 7 cases for male and 14 cases for female, with an average age of (60.70±8.75) years old (ranged 43 to 75 years old). Non-infection group 56 included cases, 24 cases for male and 32 cases for female, with an average age (64.40±12.14) years old (ranged 43 to 85 years old). Concentration of preoperative serum procalcitonin was examined and the chi-square test was used to compare positive rate between the two groups.@*RESULTS@#Two cases in the infection group had positive serum procalcitonin, 0.06 ng/L and 0.10 ng/L respectively, with the positive rate of 9.52%; 4 cases in non-infected group had positive serum procalcitonin, 0.05 ng/L, 0.06 ng/L, 0.06 ng/L, 0.16 ng/L respectively, with the positive rate of 7.14%. No statistically significant difference was observed between the two groups (=0.662).@*CONCLUSIONS@#Most of PJI were low toxicity infection with little systemic inflammatory response, so the concentration of serum procalcitonin was normal or slightly higher level, had little clinical significance for diagnosis of PJI. But the cases of this retrospective study are not enough, more cases are needed for further study.

Background Trachoma is a common infectious eye disease,and its incidence is associated with region,economy and sanitary condition.To survey the prevalence status of an area is very important for the prevention and treatment of trachoma.Objective Aim of this study was to survey the prevalence of trachoma in primary and secondary school students of Chifeng Keshiketengqi,and to investigate the relationship between the prevalence of trachoma with age,gender,ethnicity and living environment.Methods This was a cross-sectional study.According to cluster random sampling method,2067 students were drawn from 10 primary and secondary schools,including 1061male and 1006 female.The age of students ranged from 6 to 17 years old,with the average age (12.53 ± 2.31)years.In the taken samples,Han students were 1768,and Mongolian students were 299;the agricultural and pastoral students were 1209,and the urban students were 858.The general life factors associated with trachoma were surveyed by questionnaire.Trachoma was diagnosed and graded based to 1987 WHO Simplified Trachoma Grading Standards.Eye examinations included visual inspection,eyelids,conjunctiva and cornea neovascularization under the slit lamp microscope,and the clinical data were recorded and collected.The results were statistically analyzed by SPSS13.0 software.Results According to the sampling proportion of 10.05％,2153 students were included and 2067 students participated in this study with the response rate 96％.Trachoma was diagnosed in 972 students with a morbidity 47.0％.The prevalence rate of trachoma was increased with the ageing,and a statistically significant difference was seen among the 6-8 years group,9-11 years group,12-14 years group and 15-17 years group (x2 =11.043,P =0.011),and the prevalence of trachomatous infiltration was significantly higher than that of trachomatous folliele (x2=11.493,P＜0.05).The prevalence rate of trachoma in Han and Mongolian students was 45.8％ and 54.5％,showing a significant difference between them (x2 =6.228,P =0.013).In addition,statistically significant differences also were found in the prevalence rate of trachoma between the pastoral areas students and urban students (56.1％ vs.39.7％,x2=30.226,P =0.000),but no significant difference was seen between male and female (47.0％ vs.46.9％,x2 =0.000,P =0.995).Conclusions The trachoma prevalence rate is relatively higher in the primary and secondary students in Chifeng Keshiketeng.These results offer a basis for the prevention and treatment of trachoma.
ABSTRACT
Background With the development of phacoemulsification surgery,the minimization of the size of the incision in order to reduce the damaging of eye tissue and postoperative complications becomes a focus.Objective This study aimed to assess the clinical efficacy of coaxial phacoemulsification type cataract surgery through a 1.8 mm microincision with foldable intraocular lens (IOL) implantation in eyes with age-related cataract.Methods Informed consent was obtained from each patient at the beginning of this study.A serial case observation study was designed.Thirty-two eyes of 32 patients with age-related cataract were enrolled in the Inner Mongolia Autonomous Region People' s Hospital from April 2012 to May 2012,including 8 eyes of grade Ⅱ hard nucleus cataract,16 eyes of grade Ⅲ hard nucleus cataract and 8 eyes of grade Ⅳ hard nucleus cataract.Ocular axial length was measured by an A-mode ultrasonic apparatus,and IOL diopter was calculated using the SRK-Ⅱ formula.Under ocular surface anesthesia,a 1.8 mm clear corneal tunnel incision was made at the 10-11 o' clock position,and then an auxiliary incision was made at the 2 o' clock position.The opaque lens was extracted by routine phacoemulsification.An Akreos MI60 IOL was implanted through the 1.8 mm incision.The time and level of ultrasonic power required for phacoemulsification,postoperative visual acuity and incidence of postoperative complication were assessed.Postoperative examinations were scheduled at 1 day,1 week and 1 month after the surgery.Results All the operations proceeded smoothly.The mean phaco-time was (7.0±3.6) seconds and the mean ultrasonic power level was (15.3 ±6.1)％ among the different grades of cataract groups.The number of eyes presenting an uncorrected distance visual acuity of ≥ 0.5 was 18 (56.25％),28 (87.50％) and 30 (93.75％) 1 day,1 week and 1 month after surgery,respectively.The number of eyes with a best corrected distance visual acuity of ≥ 0.5 and 0.8 were 31(96.88％) and 26 (81.25％),respectively,1 month after surgery.Negligible changes were detected in the anterior chamber depths,and no thermal damage was found at the incision during the operation.Conclusions Coaxial phacoemulsification and IOL implantation through a 1.8 mm microincision is safe and effective.Thorough planning and precise execution are necessary.
ABSTRACT
BackgroundCataract is a leading blinding eye disease,and the prevalence of cataract varies in different regions.ObjectiveThe present study was to investigate the incidence of cataract,surgical coverage rate of cataract and postoperative visual acuity,and to propose a strategy for blindness prevention in Chifeng Keshiketengqi.Methods This is a cross-sectional survey of research.A random cluster sampling method was performed in 12 populated areas in Keshiketengqi.Inhabitants over 50 years in the region were included in this survey.This study was approved by the Ethic Committee of Inner Mongolia People' s Hospital.Informed consents were obtained orally from all the subjects.Disease history,visual acuity,intraocular pressure and regular ophthamological examinations were performed.The inclusion criteria of a pilot study and detailed protocol were employed to calculate the incidence rate of cataract.The questionnaire survey was simultaneously adopted to analyze the cataract-related factors.The surgical coverage rate of cataract in this area was calculated.ResultsIn a total 4234 inhabitants,3826 subjects participated in the survey with a response rate of 90.36％.Cataract was found in 1200 participants with an incidence rate of 31.39％.Age,the female gender and illiteracy were identified as risk factors for cataract (x2 =101.005,P =0.000 ;x2 =58.853,P =0.000 ;x2 =12.037,P =0.007 ).The prevalence rates of cataract were 36.98％ and 33.56％ for illiterates and women,respectively.The incidence rate in the Mongol population was significantly higher than that of the Han population ( 34.83％ vs.29.76％ ) (x2 =9.734,P =0.001 ).The cataract surgery rate increased yearly since 1998.When the vision acuity of the fellow eye was ＜0.1,the surgery coverage rate was 20.60％,but the rates were lower in female,illiterates and the Mongol population (x2 =1.993,P =0.038 ;x2 =16.463,P =0.044 ;x2 =8.523,P =0.029).When a pinhole visual acuity of ＜0.05 was determined as the criteria of blindness,the surgical coverage rate was 28.36％.The cataract surgical coverage rates for Han and Mongolian were 30.67％ and 24.53％,respectively,with a significant difference between them (x2 =12.951,P=0.000).The social burden rate was 3.34％ in this area,with a majority of females,illiterates and the Mongol population ( P＜0.05 ).ConclusionsIn agricultural and pastoral areas of Chifeng Keshiketengqi,the ≥50 years old population has a high rate of cataract blindness and low surgery coverage rate.Surgery is still the preferred way for cataract treatment.

ABSTRACT
<p><b>OBJECTIVE</b>To explore the impacts of traditional Chinese medicine (TCM) on CD4 + T cell counts and human immunodeficiency virus (HIV) viral loads during the course of structured treatment interruption (STI) in highly active antiretroviral therapy (HAART).</p><p><b>METHODS</b>Nineteen HIV/ADIS patients were treated for 14 months as follows: initiated with zidovudine/lamivudine + efavirdine for 6 months, then discontinued the therapy and treated with TCM instead for 2 months. HAART was then reinitiated for another 3 months, and then discontinued and replaced with TCM for another 3 months. The changes of CD4 + T cell counts and HIV viral loads were measured.</p><p><b>RESULTS</b>During the first STI of HAART, 43.8% of patients had no viral rebounds one month later, and 62.6% had stable or increased immune functions; 18.8% had no viral rebounds two months later, and 43.8% had stable or increased immune functions. Changes of viral loads were not significantly different between these two months (P = 0.097), while CD4 + T cell counts significantly decreased two months later compared with one month later (P = 0.043). During the second STI of HAART, 33.3% of patients had no viral rebounds one month later, and 64.3% had stable or increased immune functions; 13.3% had no viral rebounds 3 months later and 46.6% had stable or increased immune functions. Changes of viral loads had significant difference (P = 0. 017), while CD4 + T cell counts at month 12 elevated significantly compared with the baseline (P = 0.014).</p><p><b>CONCLUSIONS</b>TCM can suppress the viral rebounds during STI-HAART, maintain immune functions. However, this effect may decrease along with the prolongation of STI-HAART.</p>

<p><b>OBJECTIVE</b>To study on the dynamics of peripheral blood lymphocytes and their subpopulations in patients with severe acute respiratory syndrome.</p><p><b>METHODS</b>Using flow cytometry, the absolute numbers of peripheral blood lymphocytes and their subpopulations in 240 SARS patients (696 specimens) and 51 individuals as controls, were counted and compared.</p><p><b>RESULTS</b>The absolute numbers of peripheral blood lymphocytes and their subpopulations (CD45, CD3, CD4, CD8) were 1298 +/- 785, 897 +/- 606, 510 +/- 372, 362 +/- 263/mm(3), respectively, significantly lower in SARS patients as compared to the normal controls (2024 +/- 423, 1391 +/- 289, 795 +/- 129, 551 +/- 183/mm(3)). Of SARS patients, severe group (1095 +/- 740, 740 +/- 562, 419 +/- 346, 304 +/- 244/mm(3)) had lower counts than that of mild group (1404 +/- 788, 991 +/- 612, 564 +/- 378, 396 +/- 267/mm(3)), and in group with deaths (587 +/- 493, 369 +/- 371, 204 +/- 191, 150 +/- 130/mm(3)) was lower than that of recovery group (1355 +/- 776, 948 +/- 603, 539 +/- 375, 382 +/- 263/mm(3)). There were significant differences (P < 0.01) for CD45, CD3, CD4, CD8, but with no significant difference (P > 0.05) for CD4/CD8 ratio between severe and mild, recovery and death groups. The lymphocytes and their subpopulations (CD45, CD3, CD4, CD8) declined in the 1st week and to the lowest level (977 +/- 579, 641 +/- 466, 360 +/- 275, 270 +/- 216/mm(3)) in the 2nd week. Then the lymphocytes and their subpopulations gradually increased during the recovery of the disease.</p><p><b>CONCLUSION</b>The absolute numbers of peripheral blood lymphocytes and their subpopulations in SARS patients might be used as one of the methods for diagnosis on the severity and prognosis of the disease.</p>
