Abstract: Objective The purpose of this study is to find out the epidemiological and clinical characteristics of male patients with condyloma acuminatum (CA) in Liaocheng area, as well as to improve the understanding of human papillomavirus (HPV) infection and put forward targeted prevention and treatment measures. Methods The clinical data of 159 male CA patients who admitted to Liaocheng People's Hospital from January 2021 to January 2022 were collected, and the epidemiological characteristics, clinical manifestations, infection sites, HPV gene subtypes and other information were analyzed retrospectively. Results Most of the 159 CA patients (range from 15 to 77 years old) were 31-40 years old (31.45%, 50/159), more than half of them had smoking history, and more than 60% had low income (<5 000 yuan/month), multiple sexual partners (≥2) and no condom use habit, 70.44% of the patients had prepuce long combined with prepuce balanitis. 91 cases (57.23%) were single infection, 102 cases (64.15%) were simple low-risk HPV infection. The analysis of risk factors between mixed infection and simple low-risk infection found statistically significant differences in age≤ 40 years old, unmarried, or less affected by education duration of 15 years or less, engaged in the business or service industry, the number of sexual partners or 2, knew not to clean and not to use condoms, while differences in smoking history, alcohol history, monthly income level, and age at first sexual intercourse were not statistically significant. Low-risk HPV6 and/or HPV11 were detected in 139 cases (87.42%). Fifty-seven patients (35.85%) were infected with at least one high-risk HPV. 72.33% of the patients had multiple warts, and the most common sites were around the coronal sulcus and frenulum of the penis Conclusions The incidence of multiple infections and high-risk subtypes is high in male CA patients in Liaocheng area, and most of the patients have low income, low education level and multiple sexual partners. Strengthening the treatment and education follow-up of this population may contribute to the treatment and prognosis of male CA in this area.

Objective To study the expressions of vascular endothelial growth factor (VEGF) and Ki-67 antigen and their correlation in human brain astrocytorna. Methods Immunohistochemistry with SP method was employed to detect the expressions of VEGF and Ki-67 in 60 human brain astrocytoma tissue (grade Ⅰ-Ⅱ 28 cases, grade Ⅲ 20 cases, grade Ⅳ 12 cases) and 30 normal tissues adjacent to the tumors. Results VEGF and Ki-67 were not expressed in the normal brain tissues adjacent to the astrocytoma, but their expressions were detected in all the astroeytoma tissues of different grades (P<0.05). High-grade astrocytomas showed significantly higher VEGF and Ki-67 expression than low-grade astrocytomas (P<0.05), and a positive correlation was noted between VEGF and Ki-67 expressions (r=0.310, P<0.05). Conclusion VEGF and Ki-67 expressions can provide important evidence for evaluating the malignancy and clinicopathologieal grading of human astrocytoma.

BACKGROUNDSuccessful treatment of gliomas in or adjacent to language areas constitutes a major challenge to neurosurgery. The present study was performed to evaluate the procedure of language mapping via intraoperative direct cortical electrical stimulation under awake anaesthesia when performed prior to resective glioma surgery.

METHODSThirty patients with gliomas and left-hemisphere dominance and, who underwent language mapping via intraoperative direct cortical electrical stimulation under awake anaesthesia before resective glioma surgery, were analyzed retrospectively. All patients had tumors in or adjacent to cortical language areas. The brain lesions were removed according to anatomic-functional boundaries with preservation of areas of language function. Both preoperative and postoperative functional findings were evaluated.

RESULTSIntraoperative language areas were detected in 20 patients but not in four patients. Language mapping failure for reasons attributable to the anaesthesia or to an intraoperative increase in intracranial pressure occurred in six cases. Seven patients presented with moderate or severe language deficits after six months of follow-up. Total resection was achieved in 14 cases, near-total resection in 12 cases and subtotal resection in four cases.

CONCLUSIONSIntraoperative cortical electrical stimulation is an accurate and safe approach to identification of the language cortex. Awake craniotomy intraoperative cortical electrical stimulation, in combination with presurgical neurological functional imaging to identify the anatomic-functional boundaries of tumor resection, permits extensive tumor excision while preserving normal language function and minimizing the risk of postoperative language deficits.

OBJECTIVETo analyze the capacity of personal protection on poison emergency items in Chinese disease control and prevention institutes.

METHODSEvaluation analysis based on data obtained from investigating personal protection equipments and professional knowledge quizzing about personal protection in poisoning control of 57 different level centers for disease control and prevention selected from China by a multi-stage stratified sampling.

RESULTSAll 80.70% of the institutes possessed the protection equipments, provincial, municipal, county level institutes were 100.00%, 95.24%, 66.67%, respectively, with significant statistical difference (H = 7.94, P < 0.05). The average level of the type of individual protective equipments in disease control and prevention institutes was (5.42 +/- 4.00) kinds, the average points in category of provincial, municipal, county level institutes were (11.33 +/- 3.67), (6.52 +/- 3.16), (3.47 +/- 3.10) kinds, being statistically significant (F = 17.30, P < 0.05); type difference counts of disease control and prevention institutes in economic development, secondary, less-developed regions were (6.41 +/- 4.03), (3.55 +/- 3.35), (6.45 +/- 4.07) kinds, with statistical significance (F = 3.70, P < 0.05). Protection equipments chiefly possessed were latex gloves, gauze masks and C-protective clothing. Protective clothing and respiratory protective equipments were insufficient evidently. The average points in testing personal protection basic knowledge were (71.39 +/- 12.52) points; there were no differences between different institutes with different economic regions, levels, technical posts and title degrees.

CONCLUSIONCertain advances have been achieved in recent years in personal protection capacity of institutes for disease control and prevention, but far from the actual demands, and maybe no enough effective response on emergency occurred.

BACKGROUNDOne of the major characteristics of the human immunodeficiency virus type 1 (HIV-1) is its unusually high degree of genetic variability, which involves in genetic diagnosis, subtyping, vaccine design, and epidemiology. HIV-1 CRF01_AE is a main prevalent HIV-1 recombinant strain in China. In this study, three full-length CRF01_AE genomes from Fujian Province, China were cloned, sequenced, and analyzed; and the further genetic diversity defining and epidemiologic analysis were carried out.

METHODSProviral DNA was extracted from non-cultured peripheral blood mononuclear cells, the near full-length HIV-1 genome was amplified and the PCR products were cloned into pCR-XL-TOPO vector and sequenced. 5'-long terminal repeat (LTR) and 3'-LTRs were amplified by additional independent PCR and cloned into pMD18T vector. Gene-based phylogenic tree was constructed and genetic distances were calculated by MEGA 3.1. Simplot was used for Bootscan analysis.

RESULTSThe phylogeny and genetic distance analysis of the three near full-length sequences confirmed that these three samples clustered with CRF01_AE isolates, more close to Thailand CRF01_AE strain CM240, and were distantly related to African CRF01_AE strain 90CF402. Analysis of their genomic organization revealed the presence of nine potential open reading frames. There were no major deletions, rearrangements, or insertions in the three sequences, but an in-frame stop codon was found in tat gene of Fj051. LTRs of the three sequences contained a few nucleotides mutation. We did not find new mosaic recombinant in the three sequences. The V3 motif was GPGQ in all the three sequences, and there were only few amino acids differences in all three V3 loop sequences.

CONCLUSIONThis report reveals the background of the three full-length CRF01_AE genomes, the most dominantly circulating HIV-1 strain in Fujian Province, China. The work is essential for the design and development of an effective AIDS vaccine for the region.

BACKGROUNDBlood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) plays an important role in identifying functional cortical areas of the brain, especially in patients with gliomas. This study aimed to assess the value of fMRI in presurgical planning and functional outcome of patients with gliomas in the motor cortical areas.

METHODSTwenty-six patients with gliomas in the motor cortex were recruited in the study. Before operation, fMRI was performed in each patient to obtain the mapping of bilateral hands area on the primary sensorimotor cortex. This examination was performed on a 3.0T scanner with a bilateral hands movement paradigm. During microsurgery under awake anesthesia, the motor area was identified using direct electrical stimulation and compared with preoperative mapping. Finally the tumor was resected as much as possible with the motor cortex preserved in each patient. Karnofsky performance status (KPS) was evaluated in all patients before and after operation.

RESULTSTwenty-three patients showed a successful fMRI mapping. Among them, 19 were classified to be grade III; 4, grade II; 3, grade I. The operation time was about 7 hours in the 23 patients, 8.5 hours in the other 3. The pre- and postoperative KPS score was 82.3 +/- 8.6 and 94.2 +/- 8.1, respectively.

CONCLUSIONSPreoperative fMRI of the hand motor area shows a high consistency with intraoperative cortical electronic stimulation. Combined use of the two methods shows a maximum benefit in surgical treatment.

OBJECTIVETo explore the prevalence of vision, mental, audibility, language, psychiatry, extremity, and influence factors in the 0 - 7 year olds.

METHODSA total number of 77,727 0 - 7 year old children living in Shenzhen city were tested with tree phase screening under the Chinese standard of evaluation in disabilities.

RESULTSThe prevalence of all disabilities was 5.59 per thousand (adjusted rate was 8.49 per thousand with a false negative of 3.1 per thousand ). The prevalence of mental disease was the highest (1.88 per thousand, with adjusted rate 3.43 per thousand ), the prevalence of language disability was 1.88 per thousand (including retarded language development, with adjusted rate 3.43 per thousand ). The prevalence rates of psychiatry, extremity and audibility disability were 1.59 per thousand, 1.56 per thousand, 1.11 per thousand respectively with of vision the lowest (0.37 per thousand ). The prevalence of all disabilities, audibility, language and mental was on the increase with age. The difference was statistically significant. Among all different age groups regarding psychiatric disease, the highest fell in the 2 - 4 year olds. The prevalence of extremity was not statistically different among age groups. The suspected agents of disease which occurred before or during pregnancy took up 45.7%.

CONCLUSIONThe prevalence of six kinds disabilities in Shenzhen was about 10 per thousand lower than that of the samples of the nation in 1989, but two times higher than that of similar studies in Japan. The prevalence rates of language and psychiatric disease were higher than that of the nation in 1989. The causation should be further studied.

Objective: To investigate the current status of antithrombotic strategy for elderly patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) after stent implantation in Beijing area and to study the safety and efficacy of different therapeutic strategy. Methods: A total of 467 relevant patients were enrolled by re-travelling electronic medical records from 12 hospitals in Beijing area. The patients' mean age was (78.70±3.32) years and they were divided into 2 groups by antithrombotic therapy condition: Triple therapy group, n=17 (3.64％), Double therapy group, n=450 (96.36％). The incidence of major adverse cardiac and cerebral events (MACCE) including all-caused death, non-fatal myocardial infarction, stent thrombosis, target vessel revascularization (TVR), stoke and bleeding was compared between Triple therapy group and Double therapy group.Results: The medication in Double therapy group included aspirin+ticagrelor, aspirin+clopidogrel, clopidogrel+warfarin and cilostazol+clopidogrel; in Triple therapy group was aspirin+clopidogrel+warfarin. Patient with HAS-BLED score≥3 was defined as high risk of bleeding and they were all treated by double therapy; HAS-BLED<3 was defined as low risk of bleeding, only 5.03％ patients were treated by triple therapy. 3 patients in Triple therapy group and 33 in Double therapy group suffered from gastrointestinal bleeding, P=0.338; 6 patients in Triple therapy group and 128 in Double therapy group had MACCE, P=0.589; 3 and 80 patients died in Triple therapy group and Double therapy group, P=0.766. Conclusion: Triple therapy was rarely used in elderly AF and ACS patients after stent implantation, double therapy was the main strategy; the incidence of MACCE and mortality were similar between triple and double therapies; patients with triple therapy had the higher incidence of gastrointestinal bleeding.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.
