Objective To report the experiences on the diagnosis and treatment of duplication of kidney ureter and bladder. Methods Nine cases of duplication of kidney ureter and bladder from 1996 to 2008 were reviewed.Six cases of duplicated kidney ureter occurred in the left side and 2 cases in the right side,1 case bilateral kidney ureteral duplication.Of 8 cases with unilateral duplicated,duplicated bladders were incompleteness.And the patient with bilateral duplicated,whose duplicated bladder was completeness,was diagnosed with duplication of urethra,uterine,bilateral ovary and oviduet tubes,and also suffered from duplicated uterine prolapse Ⅱ,vaginal anterior wall bulging and duplicated vesicocele.There were two cases whose duplicated kidney losed function because of severe hydronephrosis,and 7 cases existed kidney secretion function. Excision of duplicated kidney ureter and bladder were performed on 2 cases with non-functional duplicated kidney.6 cases had undergone duplicated bladder excision and duplicated ureteral bladder replantation.The special case had undergone duplicated urinary bladder urethra uterine and bilateral annexes excision,and duplicated ureteral bladder replantation. Results The operation was successful in all paients without leakage and ureter stump syndrome.Three months after operation,ureter bladder imaging showed no ureteral reflux in 7 cases of ureteral bladder replantation.IVU were reviewed 12 months after operation:2 cases undergoing duplicated kidney excision showed that the function of residual kidney were normal,7 cases of replantation that the shape and function of sick side kidney and duplicated kidney were good. The patient who suffered from duplicated uterine simultaneously got pregnancy 1.5 years after operation. Conclsions Image examinations may help to diagnose the duplication of kidney ureter and bladder. The main treatment is surgery. Understanding the function of duplicated kidney and the shape of kidney ureter and bladder should be considered before operation. The goal of surgery should be relieving pain,protecting the function of duplicated kidney and minimizing the risk of infection.

Objective To study the expression of kallikrein 7 (KLK7) in different prostate tissues and its clinical significance. Methods KLK7 mRNA levels in normal prostate epithelia (5 cases), benign prostat(ic) hyperplasia (BPH) epithelia (13 cases), prostate cancer and prostate cancer cell lines (8 cases) were analyzed by using semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). Western blot was used to analyze the protein levels of human kallikrein 7 (hK7) in benign prostate epithelia and prostate cancer cell lines, hK7 expressions were examined in 20 normal prostate tissue specimens, 50 BPH specimens and 103 prostate cancer specimens by immunohistochemical staining.Results The mRNA levels of KLK7 in normal prostate, BPH and prostate cancer were 0.59, 0.52 and 0.02 respectively, mRNA levels of KLK7 were significantly different among the three groups (F=13.03, P＜0.01). mRNA levels of KLK7 were decreased in prostate cancers compared with that in benign hyperplastic prostate epithelial cells (P＜0.01) and in normal prostate epithelial cells (P＜0.01). No significant difference of KLK7 mRNA levels was found between normal prostate and BPH. The protein levels of KLK7 in normal prostate, BPH, DU145, LNCaP, PC3,22RV1 and BPH1 was 0.22, O. 40, 0.01, 0.05, 0, 0.03 and 0.14 respectively, hK7 protein level was down-regulated in prostate cancer cell lines compared to benign prostate epithelial cells. The expression of bK7 was observed in benign prostate epithelial cells, whereas little or no staining was observed in prostate cancer cells in immunohistochemical study, hK7 protein was detected in 13 of 20 (65%)normal prostate specimens, 38 of 50 (76%) BPH specimens and 18 of 103 (17.5%) prostate cancer specimens. The difference between the normal prostate and prostate cancer was significant (Z=-4.43, P＜0.01). The difference between BPH and prostate cancer was significant (Z=-7.77,P＜0.01) as well. However, no significant difference of hK7 protein level was found between normal prostate and BPH (Z=-1. 52, P＞0.05). Conclusions KLK7 expression level is down regulated in prostate cancer. KLK7 may play an important role in prostate cancer progression.

Objective To investigate the epidemiologic and clinical features of human immunodeficiency virus (HIV)/hepatitis B virus (HBV)co-infected patients.Methods Patients who confirmed with HIV infection and received highly active anti-retroviral therapy (HAART)at Guangzhou Eighth People′s Hospital were enrolled.HIV/HBV co-infected patients and HIV mono-infected patients were screened and their epidemiological and clinical features were analyzed before HAART.Comparison of the levels of alanine transaminase (ALT),aspartate transaminase (AST),CD4 + T lymphocyte and HIV RNA between the two groups were conducted.The data were statistically analyzed by chi-square test and nonparametric test.Results One hundred and sixty-five out of 1 218 (13.5 %)patients were hepatitis B surface antigen positive.The median ALT and AST levels of HIV mono-infected patients were 29 U/L and 34 U/L respectively,which were both higher than HIV/HBV co-infected patients (22 U/L and 25 U/L, respectively)(Z = - 4.270 and Z = - 5 .780,respectively,both P = 0.000 ).The median CD4 + T lymphocyte count of HIV/HBV co-infected patients was significantly lower than that of HIV mono-infected patients (Z = -2.980,P =0.003 ).The CD4 + T lymphocyte count was lower in hepatitis B e antigen (HBeAg)positive patients than HBeAg negative patients (Z =-2.660,P =0.008).The median CD4 + T lymphocyte count in patients with HBV DNA≥5 lg copy/mL was significantly lower than those with HBV DNA<5 lg copy/mL (Z = -2.311 ,P =0.021 ).The proportions of positive HBV DNA, HBV DNA≥5 lg copy/mL,abnormal ALT and AST in 54 patiens with CD4 + T lymphocyte counts <50/μL were 81 .5 %,66.7%,44.4% and 53.7%,respectively.All were significantly higher than patients with CD4 + T lymphocyte count≥50/μL(χ2 =6.159,P =0.046 ;χ2 =6.618,P =0.037 ;χ2 =7.144,P =0.028 andχ2 =9.586,P =0.008,respectively).Conclusions The prevalence of HBV/HIV co-infection is high in this study.The CD4 + T lymphocyte counts in HIV/HBV co-infected patients are lower,especially in patients with HBeAg positive and high HBV DNA level.The CD4 + T lymphocyte counts are associated with HBV DNA replication levels.

Objective To explore whether the mitochondrial toxicity markers of peripheral blood mononuclear cells (PBMC)are of significance in monitoring mitochondrial toxicity during highly active antiretroviral therapy (HAART)in patients with acquired immune deficiency syndrome (AIDS).Methods Mitochondrial DNA (mtDNA),mitochondrial thymidine kinase (TK2 )and p53-inducible ribonucleotide reductase small subunit 2 (p53R2 )were selected as mitochondrial toxicity markers.The expression changes of theses markers of PBMC in 22 AIDS patients were detected by real time quantitative polymerase chain reaction (q-PCR)at baseline,48 weeks and 96 weeks after initiation of the treatment. All the patients received stavudine/zidovudine and lamivudine as the mainstay of the HAART regimen. Independent-samples t test was used.Results The relative expression level of mtDNA in patients before HAART was 3.27 ± 0.94,and decreased to 2.16±0.85 at week 48 and 1 .66±0.66 at week 96, respectively.The differences were both significant compared with the level prior to the treatment (t =-3.90,P <0.01 and t =-6.29,P <0.01 ,respectively).The relative expression level of TK2 before HAART was 0.37 ±0.13,and increased to 1 .01 ±0.25 at week 48 and 2.13 ±0.61 at week 96 of the treatment.After pairwise comparisons of the three pairs of data (pre-HAART vs week 48 of the treatment,pre-HAART vs week 96 of the treatment and week 48 vs week 96 of the treatment),the differences were all significant (t = 10.77,8.00 and 3.56,respectively;all P < 0.01 ).The relative expression level of p53R2 was 0.86±0.39 before HAART,but gradually increased to 2.36 ±1 .14 and 7.73±0.65 ,respectively,at week 48 and week 96 of the treatment.The differences in p53R2 levels among three groups after pairwise comparison were all significant (t=3.27,12.26 and 13.25,respectively;all P < 0.01 ).Conclusions The expression levels of mtDNA,TK2 and p53R2 in PBMC could change significantly during HAART in AIDS patients,which might be used as indexes for monitoring mitochondrial toxicity.

Objective To investigate the prevalence and risk factors of highly active antiretroviral therapy (HAART)-associated lipodystrophy syndrome (LD) in patients with acquired immunodeficiency syndrome (AIDS) treated with HAART in China.Methods A total of 137 AIDS patients treated with HAART for more than 2 years were analyzed.Sixteen clinical parameters (including gender,age,baseline body mass index,baseline human immunodeficiency virus [HIV] viral load,stage of disease,routes of HIV transmission,baseline CD4+ T lymphocyte count,white blood cell count,fasting plasma glucose level,serum triglycerides level,serum cholesterol level and other laboratory results,and HAART regimens) that might be associated with HAART-LD occurrence were evaluated using Cox proportional hazards models.Results HAART regimens were significantly correlated with HAART-LD (P=0.031),while the remaining 15 factors were not associated with the risk of HAART-LD (all P＞0.05).Patients who received stavudine d4T)-containing regimen was 2.684 times more likely to develop HAART-LD than patients who received zidovudine (AZT)-containing regimen (95 ％ CI:1.302-5.531,P=0.007) ; HAART-LD prevalence rates were gradually increased with treatment duration in both groups.First HAART-LD was seen at 24 weeks in both d4T group and AZT group,and the prevalence rates were 2.7％,1.6％ at 24 weeks,27.0％,7.9％ at 48 weeks and 37.8％,15.9％ at 96 weeks respectively.The prevalence of HAART-LD in d4T group was much higher than that in AZT group and the difference was statistically significant (x2 =8.285,P=0.004).Conclusions HAART regimen is an independent predictor of HAART-LD.HAART-LD tend to occur more frequently in patients treated with d4T or AZT,especially d4T.Our study recommends to avoid the use of d4T-contained HAART regimen.

Objective To investigate the clinical efficacy of a needle knife in treating knee meniscus injury. Methods One hundred patients with knee meniscus injury (112 knee joints) were randomly allocated to treatment and control groups, 50 cases each. The treatment group received needle knife therapy and the control group, an injection of sodium hyaluronate injectio into knee joint cavity. The main clinical symptoms and signs around the knee joint were observed and the knee function score was recorded in the two groups before and after treatment. the clinical therapeutic effects were evaluated in the two groups. Results There were statistically significant differences in pre-/post-treatment main clinical symptom and sign index (pain score, swelling score, activity score and tenderness index score) difference values between the two groups (P<0.05). There were statistically significant differences in the main clinical symptom and sign index difference values at follow-up compared with before treatment between the two groups (P<0.05). There was a statistically significant differences in the knee function score after treatment and at follow-up compared with before treatment in the two groups (P<0.01,P<0.05). There was a statistically significant differences in the knee function score between the treatment and control groups after treatment and at follow-up (P<0.05). Post-treatment excellence rate and total efficacy rate were 94.0%and 100.0%, respectively, in the treatment group and 72.0%and 98.0%, respectively, in the control group. There was a statistically significant differences in post-treatment excellence rate between the two groups (P<0.05). Follow-up excellence rate and total efficacy rate were 96.0% and 100.0%, respectively, in the treatment group and 76.0% and 98.0%, respectively, in the control group. There was a statistically significant differences in follow-up excellence rate between the two groups (P<0.05). Conclusion Needle knife therapy is an effective way to treat knee meniscus injury.

BACKGROUND:The mechanism underlying Wal erian degeneration fol owing peripheral nerve injury is complex. Immune regulation on Wal erian degeneration is beneficial for early repair of perpheral nerve injury.
OBJECTIVE:To investigate the effects of Tol-like receptor 4 (TLR4) antagonist on Wal erian degeneration and axonal regeneration after early peripheral nerve injury in rats.
METHODS:Fifty male Wistar rats were recruited and randomly divided into treatment group (n=20), model group (n=20) and sham group (n=10). The right sciatic nerves of rats in treatment and model groups were cut and sutured end-to-end, while the sciatic nerves of rats in sham group were only exposed. In the treatment group rats were intravenously injected with 0.15 mg/kg TAK-242 via tail vein 1 hour preoperatively and 7 days postoperatively, and the rats in the other two groups were given intravenous injection of the same volume of normal saline. The sciatic nerves were removed at 24 hours, 3, 4 and 7 days after surgery.
RESULTS AND CONCLUSION:Real-time PCR indicated that the mRNA expressions of interleukin-1βand monocyte chemoattractant-1 were significantly increased in the model group compared with the sham group at 24 hours after surgery (both P<0.001), while the expressions were significantly decreased after TAK-242 injection (both P<0.001). Immunofluorescence showed that compared with the model group, down-regulated expression of CD68+and iba1+cel s appeared in the treatment group at 3 days after surgery (P<0.01, P<0.05). Luxol fast blue staining revealed that demyelination at the sciatic nerve stump appeared in both model and treatment groups at postoperative 7 days, but myelin debris clearance in the treatment group was significantly reduced compared with the model group (P<0.05). Hematoxylin-eosin staining showed that a lot of inflammatory cel s, Schwann cells and regenerated nerve fibers at the sciatic nerve stump were found in the model group, while there were few inflammatory cells, Schwann cel s and regenerated nerve fibers in the treatment group at 7 days after surgery. Immunohistochemistry found that the expression of growth-associated protein-43 in the treatment group was significantly lower than that in the model group at 4 days postoperatively (P<0.05). Besides, compared with the model group, a significantly decreased sciatic functional index was found in the treatment group at 20, 30 and 40 days after surgery (P<0.05). These results show that TLR4 antagonists delay early nerve regeneration in rats after sciatic nerve injury probably by inhibiting the TLR4 signaling pathway.

ObjectiveTo observe andanalyze the clinical efficacy of needle knife treatment for knee meniscus injury from improving knee biomechanical balance and to provide a therapeutic basis and method for clinical practice.MethodOne hundred patients (112 knees) with knee meniscus injury meeting the inclusion criteria were allocated, in order of visits, to observation and control groups, 50 cases each. They were treated with a needle knife and an injection of sodium hyaluronate injectio into knee joint cavity, respectively. Changes in the indices were observed and assessed in the two groups by recording the plantar pressure analysis score and the knee function score before and after treatment and at follow-up. The clinical therapeutic effects were evaluated in the two groups.ResultThemaximum load, time integral difference value and load ratio around the knee joint decreased significantly in both observation and control groups after treatment and at follow-up (P<0.05). The regulating effect on knee joint force balance was better in theneedle knife group than in the control group (P<0.05). The improving effect on knee joint function was significantly better in the observation group than in the control group (P<0.01). The excellence rate was significantly higher in the observation groupthan in the control group after treatment and at follow-up (P<0.05).ConclusionNeedle knife treatment restores the function of the knee joint by loosing focal soft tissues around the knee joint, improving knee joint load imbalance and correcting the mechanical equilibrium around the knee joint in patient with knee meniscus injury. It has a definite curative effect on the disease.

OBJECTIVE: To explore the molecular basis for a pedigree affected with coagulation factor V (FV) deficiency. METHODS: Clinical data of the patient and his family members was analyzed. Targeted capture and next-generation sequencing (NGS) and Sanger sequencing were carried out to detect potential variant of the FV gene. RESULTS: The patient presented with jaundice and prolonged prothrombin time (PT) and activated partial thromboplastic time (APTT). V factor activity measured only 0.1% of the normal level, though the patient had no sign of bleeding. A paternal heterozygous variant c.653T>C (p.F218S) and a maternal heterozygous variant c.3642_3643del (p.P1215Rfs*175) were identified in the FV gene of the patient. His elder brother was a heterozygous carrier of the c.653T>C (p.F218S) variant. c.653T>C(p.F218S) was a known pathogenic variant, while the c.3642_3643del (p.P1215Rfs*175) variant was unreported previously. CONCLUSION Mutations of the FV gene probably underlie the hereditary coagulation factor V deficiency in this patient. NGS combined with Sanger sequencing has detected potential variant with efficiency and provided a reliable basis for clinical and prenatal diagnosis for this family.

Objective:To explore the protective effect of nerve plane-oriented laparoscopic total mesorectal excision (NPO+ LTME) for postoperative urinary and sexual function in patients with rectal cancer.Methods:Retrospective analysis was performed on rectal cancer patients who received surgical treatment at Renmin Hospital of Wuhan University from Jan 2016 to Dec 2018, including 114 patients in the NPO+ LTME group and 92 patients in the laparoscopic TME combined with pelvic autonomic nerve preservation (LTME+ PANP) group. Surgical and tumor-related indicators were recorded and compared between the two groups, and postoperative urination and sexual function were followed up.Results:There was no significant difference in baseline indicators between the two groups ( P>0.05). The operative time of the two groups was (150±7) min and (154±7) min, respectively ( t=3.585, P<0.05). Intraoperative bleeding was (9±3) ml and (15±6) ml ( t=7.654, P<0.05), respectively.Three months after surgery, the rate of urinary dysfunction in the NPO+ LTME group was lower than that in the LTME+ PANP group ( Z=2.549, P<0.05), but there was no difference between the two groups 6 and 12 months after surgery ( Z=0.814, P>0.05 and Z=1.275, P>0.05). At 3, 6 and 12 months after surgery, the erectile function in NPO+ LTME group was better than that in LTME+ PANP group ( Z=4.917, P<0.05; Z=4.947, P<0.05 and Z=4.081, P<0.05); The rate of ejaculation dysfunction was also lower than that of the LTME+ PANP group ( Z=4.464, P<0.05; Z=4.948, P<0.05 and Z=4.434, P<0.05); In addition, postoperative female sexual function was superior to LTME+ PANP group ( Z=2.532, P<0.05; Z=2.364, P<0.05; Z=2.076, P<0.05). Conclusion:NPO+ LTME has good surgical safety and also has certain advantages for patient sexual function and early urinary function protection.
