ABSTRACT
@#Abstract: Objective To investigate the correlation between persistent and non-persistent HPV infection and vaginal microecology and cervical lesions, and to provide the basis for HPV prevention and treatment. Methods In this prospective study, 229 female patients with high-risk type (HR-HPV) were selected for cervical cytology and vaginal microecological examination in the gynecological outpatient department of Baise Maternal and Child Health Hospital from January 2018 to June 2021. The patients were followed up for 1 year to detect persistent HR-HPV infection. The relationship between HR-HPV persistent infection and vaginal microecology and cervical lesions was analyzed using the HPV-negative group as a control. Results Among 229 patients with HR-HPV, there were 109 patients with persistent HR-HPV infection and 120 patients with non-persistent HR-HPV infection in 1-year follow-up, and the incidence of persistent HR-HPV infection was 47.6%. In the HR-HPV persistent and non-persistent infection and HPV-negative groups, the bacterial vaginal incidence was 20.2%, 15.0% and 8.6%, respectively; vulvovaginal candidiasis was 19.3%, 13.3% and 7.9%, respectively; trichomoniasis vaginitis was 12.8%, 9.2% and 4.5%, respectively; mixed infection was 10.1%, 6.7% and 2.7%; H2O2 detection rate was 24.8%, 18.3% and 12.0%,the positive rate of pH value was 52.3%, 40.8% and 36.4%, and microecological normal detection rate was 22.9%, 32.7% and 40.2%, respectively. There were significant differences among the three groups (χ2=10.634, 10.522, 9.010, 9.374, 10.054, 8.268, P<0.01). In the HR-HPV persistent and non-persistent infection groups, the rates of atypical squamous cell detection were 12.8% and 10.0%, and 8.3% and 4.2% for low-grade squamous cell lesions, and 4.6% and 1.7% for high-grade squamous cell carcinoma, 2.8% and 0 for squamous cell carcinoma, respectively. There was no significant difference in the composition of atypical squamous cells between the two groups (χ2=4.358, P>0.05), there were significant differences in the composition of low-grade, high-grade and squamous cell carcinoma (χ2=11.472, 12.685, 11.378, P<0.01). Spearman rank correlation analysis showed that the presence or extent of HPV infection was positively correlated with bacterial vaginosis, vulvovaginal candidiasis, trichomonal vaginitis and mixed infection (P<0.05), positively correlated with H2O2, sialdase, leucocyte esterase,pH positive and positive for all four items (P<0.05), negatively correlated with microecology (P<0.01), positively correlated with low grade, high grade and squamous cell carcinoma (P<0.01), and not significantly correlated with atypical squamous cell carcinoma (P>0.05). Conclusion Persistent cervical HPV infection is an important factor of dysregulation in vaginal microecology and aggravates the degree of dysregulation in vaginal microecology, which is related to the development of cervical lesions.

ABSTRACT
Objective To evaluate the evolution of the effective and safe diagnostic and surgical approaches for patients with cervical cancer of stage Ⅰ A1 during ten years.Methods A retrospective cohort study of 721 cases diagnosed with cervical cancer of stage Ⅰ A1 from 2005 to 2014 was conducted by reviewing the archived medical records.Results Of patients with cervical cancer of stage Ⅰ A1,396 cases (54.9％) had no symptoms and follow-up materials.The transformation of treatment and curative effect were evaluated with Pearson chi square test,Spearman correlation analysis as well as Fisher's exact probability.Pathology of biopsy clarified the diagnosis for 82 cases (11.4 ％),and pathologic results of conization made the definite diagnosis for 640 cases (89.9 ％) (P＜0.01).Laparoscopy grew to be the main trend of surgical approach for cervical cancer of stage Ⅰ A1 instead of laparotomy from 2010 to 2014 compared with 2005 to 2009 (P＜0.01).Non-radical surgery became more popular to the cohort from 2010 to 2014 (P＜0.01).Thirty-five cases (4.9％) were lost to follow-up.There was no dead case and a case of recurrence.Conclusions Conization was very important to clarify the diagnosis for cervical cancer of stage Ⅰ A1.Laparoscopic hysterectomy was a safe and effective treatment for cervical cancer of stage Ⅰ A1 patients.
ABSTRACT
The accuracy and sensitivity of prostate-specific antigen (PSA) for prostate cancer diagnosis is often poor; however, the reasons for its inaccuracy have rarely been investigated, especially with respect to age. In this study, 476 healthy males, aged 10-89 years, were stratified into eight age groups, and levels of seven markers were determined: total PSA (tPSA), free PSA (fPSA), %fPSA, isoform [-2]proPSA (p2PSA), p2PSA/tPSA, %p2PSA, and the prostate health index (PHI). Both tPSA and fPSA levels increased with age. The tPSA level was highest (1.39 ng ml-1) at 70-79 years; %fPSA was highest (0.57 ng ml-1) at 10-19 years; and %p2PSA was lowest (18.33 ng ml-1) at 40-49 years. Both p2PSA and p2PSA/tPSA had relatively flat curves and showed no correlation with age (P = 0.222). PHI was a sensitive age-associated marker (P < 0.05), with two peaks and one trough. The coverage rates and radiance graphs of PHI and %p2PSA were more distinctive than those of tPSA and the other markers. In subjects older than 69 years, PHI and %p2PSA both began to decrease, approximately 10 years earlier than the decrease in tPSA. Our results suggest that the clinical diagnosis of prostate cancer using PSA should be investigated more comprehensively based on patient age. Moreover, %p2PSA and PHI could be considered as earlier markers that may be more suitable than PSA alone.
ABSTRACT
Objective To investigate the significance of the expression of serum LDH and β2-MG in predicting survival of NHL patients and there correlations with clinical parameters. Methods The serum levels of LDH and β2-MG of 429 patients with NHL were measured by rate method and immunoturbidimetry.Besides,the clinical reference of the patients such as gender,age,B symptoms,clinical stages,extranodal sites and Karnofsky evaluation were summarized and grouped.All patients' survival status were achieved via phone and letter. All statistical analyses were performed using the SPSS program for Windows (version 16.0).Results The levels of LDH and β2-MG in age,B symptom,the advanced stage,extranodal sites≥2,Karnofsky evaluation were obviously higher than their counterpart and the difference was significant (P＜0.001). The median of LDH and β2-MG lever in age group was 229 U/L,190 U/L, 2.4 mg/L,1.7 mg/L. In B symptom was 260 U/L,192 U/L,2.3 mg/L, 1.7 mg/L. In clinical stage was 252 U/L, 175 U/L, 2.5 mg/L, 1.6 mg/L. In extranodal sites group was 278 U/L,195 U/L,2.4 mg/L,1.8 mg/L.In Karnofsky evaluation group was 250 mg/L,195 mg/L,2.2 mg/L,1.8 mg/L.LDH level of invasive lymphoma was significantly higher than that of indolent ones (median 211U/L,175 U/L,P=0.002),but there were no difference in the 32-MG level (P=0.937). There were no statistical significance about LDH and β2-MG levels in gender and cell type (P＞0.05).Overall survival rates were different between the abnormal LDH group and the normal LDH group (χ2=119.029, P＜0.001).Overall survival rates were different between the elevated β2-MG group and the normal β2-MG group (χ2 =104.733,P＜0.001).Overall survival rates of the abnormal LDH/β2-MG group was significantly lower than that of normal group (x2=192.326,P＜0.001).Multivariate analysis in Cox regression showed that LDH,β2-MG,age,clinical stages, extranodal sites, Karnmofsky evaluation and aggressive were independent prognostic factors.Conclusion The level of serum LDH and β2-MG can be taken as an auxiliary clinical index to evaluate the prognosis of the NHL patients.
ABSTRACT
<p><b>OBJECTIVE</b>To search for a simple surgical procedure for the treatment of concealed penis that may have better effect and less complications.</p><p><b>METHODS</b>We used a modified surgical method in the treatment of 58 patients with concealed penis aged from 3 to 15 (mean 6.8) years. The operation was simplified and involved the following steps: wholly unveiling the penis glans, half-degloving the foreskins, cutting off all the adhesive fibers up to the penile suspensory ligaments, and liberating the external penis.</p><p><b>RESULTS</b>The operation was successful in all the patients, with the operative time of 15 -45 (mean 33) minutes, hospital stay of 2 - 5 (mean 3.5) days, but no complications except mild foreskin edema in 5 cases. The external penis was prolonged from 0.5 - 2.8 (mean 1.4) cm preoperatively to 3.2 - 8.5 (mean 3.9) cm postoperatively. The patients were followed up for 1 -3 years, all satisfied with the length and appearance of the penis, and their sexual and reproductive functions were normal.</p><p><b>CONCLUSION</b>The modified surgical procedure for concealed penis is simple and effective, with desirable outcomes, few postoperative complications and no damage to sexual and reproductive functions.</p>

<p><b>OBJECTIVE</b>To survey the prevalence of hyperuricacidemia and serum uric acid (SUA) changes and electrolyte changes after 6 weeks antihypertensive treatment with thiazide diuretics, losartan or losartan+hydrochlorothiazide (Hyzaar) in patients with essential hypertension (EH).</p><p><b>METHODS</b>A total of 1080 consecutive EH patients [662 males, mean age (60.9 +/- 12.3) years] who seeked for medical consultation in study hospitals in Fuzhou city during October 2004 and October 2006 were included in this study. The blood pressure before and after antihypertensive treatments were obtained in 1000 patients, and the renal function and electrolyte before and after antihypertensive treatments were obtained in 600 patients. Patients with SBP > 140 and/or DBP > 90 mm Hg 2 weeks after initial antihypertensive agents were cotreated with felodipine, patients with SBP > 140 and/or DBP > 90 mm Hg 4 weeks after initial antihypertensive agents were cotreated with beta and/or alpha blockers.</p><p><b>RESULTS</b>The prevalence of hyperuricacidemia in EH patients was 25.83% (279/1080). Body mass index (BMI) and creatinine were significantly higher while creatinine clearance rate (Ccr) calculated by Cockcroft-Gault equation was significantly lower in EH patients with hyperuricacidemia than EH patients without hyperuricacidemia (all P < 0.05). Similar antihypertensive effects were observed in EH patients treated with thiazide diuretics (n = 200), losartan (n = 324) or losartan + hydrochlorothiazide (Hyzaar, n = 476) and SBP was lower than 140 mm Hg in 69.40% and DBP was less than 90 mmHg in 85.30% EH patients 6 weeks after antihypertensive treatments. SUA was significantly increased (43.81 micromol/L +/- 71.79 micromol/L) low dose diuretics group (P < 0.01 vs. pretreatment), significantly reduced (44.96 micromol/L +/- 90.63 micromol/L) in losartan group (P < 0.0001 vs. pretreatment) and remained unchanged in Hyzaar group (7.46 +/- 84.72 micromol/L, P > 0.05 vs. pretreatment). Serum potassium was significantly decreased (0.30 +/- 0.44 mmol/L) in diuretic group (P < 0.01 vs. pretreatment) and remained unchanged in losartan group (+0.06 +/- 0.43 mmol/L) and Hyzaar group (-0.04 +/- 0.44 mmol/L, all P > 0.05 vs. pretreatment).</p><p><b>CONCLUSION</b>Hyperuricacidemia prevalence was 25.83% and associated with higher BMI and abnormal renal function in examined EH patients. The low dose thiazide diuretics could further aggravate hyperuricacidemia and induce hypopotassemia while losartan could reduce hyperuricacidemia in EH patients.</p>
