Objective To analyze the clinical and immunological features of 45 pediatric patients with lupus nephritis (LN). Methods Forty-five LN patients were included in this study. Clinical, pathological data and immunological parameters were retrospectively analyzed. Results Forty-five LN patients had 6 males and 39 females, with the mean onset age of (10.9 ± 2.8) years. Acute nephritis was the most common type, accounting for 42.2%. Nephrotic syndrome accounted for 31.1%. Renal biopsy showed class II (17.8%), III (4.4%), IV (48.9%), V (2.2%), V+III (6.7%)and V+IV (13.3%)in 42 cases. The remis-sion rate reached 91.1%in the early therapeutic stage, and 15.0%patients recurred after 24-month follow-up. Conclusions The clinical manifestations of LN children are diverse. The renal pathology is complex. The clinical manifestations in part of the chil-dren are not consistent with renal pathology.

Objective To explore the clinical features of psoriasis vulgaris in patients with abnormal body mass index (BMI). Methods Three hundreds and ninety-seven patients with psoriasis vulgaris were investigated by questionnaire and physical examination, among them 245 patients at the progressive stage were selected for evaluating the degree of severity. The following items were compared between BMI≥25 group and BMI0.05). In the male patients, the average age in BMI≥25 group was higher than in BMI0.05). For the female patients, the subjects in BMI≥25 group had higher mean age and initial onset age, and longer diseace course than those in BMI0.05). Conclusion The psoriasis vulgaris patients with abnormal BMI always have higher average age and initial onset age, longer clinical history and severer symptoms, especially in the females.

Objective To evaluate the prevalence of metabolic syndrome(MS) in patients with psoriasis,and explore the clinical features of the patients with metabolic syndrome-associated psoriasis.Methods Two hundred and two patients with psoriasis were investigated by face-to-face questionnaire,physical and laboratory examinations.Information included age,sex,the age of onset,duration of the disease,disease severity,family history,education level,waistline,fasting plasma glucose(FPG),triglyceride(TC),high-density lipoprotein cholesterol(HDL-C) and blood pressure(BP).The diagnosis of MS was established according to the criteria of International Diabetes Federation(IDF).Results ① Of 202 patients with psoriasis,45 suffered from metabolic syndrome,accounting for 22.27%.② The patients with metabolic syndrome-associated psoriasis always had significantly higher average age and the age of onset,longer disease history and severer symptoms than those psoriasis patients without metabolic syndrome(P0.05).③ The patients with metabolic syndrome-associated psoriasis had significantly longer waistline,fasting plasma glucose,triglyceride,blood pressure and lower high-density lipoprotein cholesterol than the psoriasis patients without metabolic syndrome(P0.05).Conclusion Metabolic syndrome is highly prevalent among the patients with psoriasis,which might be associated with smoking and drinking.

Spotted fever caused by spotted fever group rickettsiae (SFGR) is found throughout China. During 2007—2008, 28 human SFGR isolates and 34 rat SFGR isolates including 15 isolates from Rattus fulvescens, 5 isolates from R.edwardsi, 7 isolates from Callosciurus erythraeus roberti and 7 isolates from Dremomys rufigenis) were obtained from L929 cell culture. Previous research indicated that the 62 strains of SFGR mentioned above shared not only the same serophenotype but also 100% of identity sequences of 16S rRNA, gltA, ompA, groEL and 17KD, which enabled us to apply multispacer typing (MST) to the 62 SFGR isolates in the study. Six primer pairs, which were used for typing of Rickettsia rickettsii and Rickettsia conorii, were chosen, and the results exhibited greater nucleotide polymorphisms among the 62 isolates tested. A total of 48 distinct genotypes were identified. The dominant genotype, represented by h3 isolates, accounted for 21.7% (13/60) of the isolates tested, and the remaining 47 genotypes were all unique. Phylogenetic analysis showed that all the 48 genotypes could be classified in the same clade, while the genetically related strain, R.heilongjiangensis, was close but not the same as the cluster. We concluded that the genetically diverse of spotted fever group rickettsiae strains are endemic in Chengmai County, Hainan Province, China.

ObjectiveTo measure the expression of divalent metal transporter 1 (DMT1) in hepatocellular carcinoma (HCC) and to explore its clinical and pathological significance. MethodsFifty-seven liver cancer specimens collected from patients with HCC and preserved in paraffin in Second Affiliated Hospital of Shantou University Medical College from July 1999 to July 2011 were established as HCC tissue group, and 7 specimens of normal liver tissues from autopsy and 8 specimens of liver tissues from patients with intrahepatic bile duct stones and preserved in paraffin were established as normal control group. SP immunohistochemistry was applied to measure the expression of DMT1 in 15 specimens of normal liver tissues and 57 specimens of HCC tissues. One-way analysis of variance was applied to analyze the difference in expression of DMT1 in HCC tissues with varying degrees of differentiation, and χ2 test was applied for the comparison of rates; the correlation between expression of DMT1 and tumor size was analyzed by Pearson correlation analysis. ResultsDMT1 in the liver tissues in normal control group was negative or weakly positive, with a positive rate of 20% (3/5); in HCC tissue group, the positive rate was 789% (45/57), with a strong positive rate of 15.8% (9/57); the two groups showed a significant difference in positive rate (P＜0.05). The expression of DMT1 varied significantly between patients with varying degrees of differentiation in HCC tissues (F=4.011, P＜0.05), while the positive rate of DMT1 showed no significant differences between patients with different clinical stages and with or without blood vessel infiltration (all P＞0.05). Correlation analysis did not find the correlation between expression of DMT1 and tumor size (r=-0.047, P＞005). ConclusionThe positive expression rate of DMT1 increases significantly in HCC tissues and is closely related to the degree of tumor differentiation, which is potentially valuable for clinical and pathological grading of liver cancer.

Objective To detect the feasibility and safety of applying all-seeing needle in transurethral seminal vesiculoscopy.Methods Retrospective analysis was made with clinical data of 32 patients of hemospermia treated with transurethral seminal vesiculoscopy using all-seeing needle from March 2016 to January 2018.The patients'age was (38.8 ± 8.7) years (27-60 years) and the course of disease was (7.1 ±3.3) months (2-15 months).Ultrasound before operation showed heterogeneous echo,or expansion of the seminal vesicle.MRI showed hemorrhage of the seminal vesicle,or abnormal signal of the seminal vesicle.Patients had levofloxacin or mosisasin anti-infection therapy more than one month and remained uncovered.The operation was performed under subarachnoid anesthesia,and the patients took the lithotomy position.The F4.8 all-seeing needle entered the posterior urethra,the verumontanum was found,and the saline was slowly pushed with a syringe to maintain a clear view.Then,the ejaculatory duct opening was searched on both sides of the verumontanum.If the ejaculatory duct opening cannot be found in the normal position,we entered the needle into the prostatic utricle to find the possible ectopic opening.If the ejaculatory duct opening was still not found,at the 5 and 7 o'clock positions in the prostatic utricle,the needle was probed and punctured into the side wall of the ejaculatory duct.Visible puncture with all-seeing needle can effectively avoid penetrating blood vessels and reduce damage to tissues during puncture.In this study,the ejaculatory duct opening got accessed on the verumontanum in 14 cases,through ectopic openings within the prostatic utricle in 2 cases,and through artificial establishment in 5 and 7 o'clock positions within prostatic utricle in 16 cases.After entering the ejaculatory duct and seminal vesicle,we explored the cavities of the seminal vesicles.For stones or polyps,after replacing the outer sheath to F8,F1.9 stone retrieval basket was applied to remove stones or polyps,followed by rinsing the seminal vesicles with normal saline,0.02％ nitrofurazone,and then 160,000 units of gentamicin into each seminal vesicle.For hemorrhage,after clearing up the blood,seminal vesicles were also washed with normal saline,nitrofurazone,and perfused with gentamicin.In the operation,prostatic utricle stone was found in 5 cases,and seminal vesicle stone was found in 7 cases.One case of seminal vesicle polyp was observed,and in 19 cases,seminal vesicle hemorrhage was seen.Results All the operations were accomplished successfully,the operation time was (55.0 ± 11.3) min (35-82 min).There was no rectal injury or urethral injury during operation.The postoperative catheter was removed at 2 days postoperatively and the patients discharged on the 4th day after surgery.The length of hospital stay was (6.3 ± 0.7) days (5-7 days).One patient had mild hematuria after removal of the urethral catheter and got improved spontaneously;one case developed epididymitis,which improved after anti-infective treatment.6 cases made stone analysis,with 5 cases of magnesium ammonium phosphate hexahydrate,and 1 case of calcium oxalate dihydrate,calcium oxalate monohydrate and carbonate apatite mixed stones.One case of polyp was diagnosed by pathologists to be an inflammatory polyp.Follow-up was performed at 4,6,8,and 12 weeks after surgery.Hemospermia was cured in 24 cases,relieved in the other 8 cases at 8-week follow-up,who received oral antibiotic treatment afterwards.At the 12-week follow-up,the rest 6 cases in 8 got hemospermia recovered,with 2 cases still uncovered.Conclusions All-seeing needle is user-friendly and safe in transurethral seminal vesiculoscopy,with reliable short-term efficacy.
