Total 150 patients with chronic pelvic pain syndrome were randomly divided into three groups with 50 cases in each group. Patients were treated with tamsulosin, Qianlie'an Shuan and tamsulosin plus Qianlie'an Shuan for 12 weeks, respectively. Patients were assessed with the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) before and after treatment. The score of NIH-CPSI decreased from 25. 1 ± 2. 2 to 19. 5 ± 1.7 after treatment in tamsulosin group; 25.0 ± 2. 2 to 19. 1 ± 1.7 in Qianlie'an Shuan group, and 24. 8 ± 1.7 to 16. 8 ± 1.4 in combined therapy group, all P ＜0. 01. The results indicated that tamsulosin, Qianlie' an Shuan or combined therapy were all effective in alleviating the symptoms and improving the quality of life, and the combined therapy was superior to single therapy in relief of symptoms.

Objective To explore the diagnosis of tuberous sclerosis (TSC) combined with Langerhans cell histiocytosis (LCH) and secondary hemophagocytic lymphohistocytosis (HLH).Methods One case diagnosed of TSC combined wiht LCH and secondary with HLH in infancy was retrospectively analyzed.Results One year and 4-month-old Uyghur boy when he was 4-month-old,there was onset of infantile spasm.Gene detection was performed when he was one year old and showed the absence of the exon 3 to 10 ofTSC2 gene.The diagnosis of TSC was confirmed.Meanwhile,the boy also suffered with skin rash all around,fever,hepatosplenomegaly,and bone defect.The diagnosis of LCH was confirmed by skin biopsy.In addition,the boy was complicated HLH.Conclusions It is rarely seen that TSC combined with LCH,and secondary HLH in one case.The clinical features were complex and need to be differetiate.

OBJECTIVE To examine expression and distribution of fibronectin (FN) in hepatic tissues from patients with hepatitis or cirrhosis, and its correlation with serum hyaluronic acid (HA) contents. METHODS The expression and distribution of FN were detected with immunohistochemical and pathological methods in liver tissues of 66 cases, among which there were 8 cases of normal liver tissues, 58 cases of various types of hepatitis. The levels of HA in patients with liver disease were detected with radioimmunological method. RESULTS Positive cellular rate of FN in hepatocytes and endothelial cells of chronic active hepatitis (CAH) was apparently higher than those in acute hepatitis (AH) group and chrouic persistent hepatitis (CPH) group(P

BACKGROUND:Currently, cellular composition and the features of the nucleus pulposus are stil not to be clarified.
OBJECTIVE:To establish the in vitro culture system of rat nucleus pulposus-derived mesenchymal stem cells and to identify their multi-lineage differentiation potential.
METHODS:Mesenchymal stem cells from the nucleus pulposus tissues of Sprague-Dawley rats were cultured in vitro. Then, cells at passage 3 were induced to differentiate into osteoblasts, adipocytes and chondrocytes as experimental group. cells cultured with basic culture medium served as controls.
RESULTS AND CONCLUSION:cells isolated from rat nucleus pulposus could form the sunflower-like colonies and exhibit clone-like growth when they cultured at a low density. cells at passage 3 became homogeneous and exhibited fibroblast-like morphology. After 28 days of osteogenic induction, arizarin red positive signals were detected in the experimental group. The mRNA expressions of RunX2, osteopontin and osteocalcin were significantly increased in the experimental group, compared to the control group (P<0.05). After 21 days of adipogenic induction, oil red-O positive cells were detected in the experimental group. The mRNA expressions of C/EBPαand PPARγ2 were significantly increased in the experimental group, compared to the control group (P<0.05). After 21 days of chondrogenic induction, safranin O/fast green staining was positive in the experimental group. The mRNA expressions of aggrecan and Col2a1 were significantly increased in the experimental group, compared to the control group (P<0.05). Our findings in this study suggested that nucleus pulposus-derived mesenchymal stem cells could be isolated from the Sprague-Dawley rat nucleus pulposus and exhibited clonal-like growth when they were cultured in vitro. These cells were confirmed to have the potential to differentiate into adipocytes, osteoblasts and chondrocytes in vitro.

Objective To study the feasibility of a novel probe 99Tcm-HYNIC-2(poly-(ethylene glycol),PEG) 4-Dimer (Dimer:E-[c (RGDfK) 2]) as a potential imaging agent for integrin αv β3 positive tumors,and also to observe the influence of an angiogenesis inhibitor,endostar,on the biodistribution and tumor uptake of the tracer in tumor bearing nude mice.Methods The expression of integrin αv β3 in human glioma cells U87MG was determined with immunofluorescence staining before and after treatment with endostar.99Tcm-HYNIC-2PEG4-Dimer was prepared and administered in U87MG tumor bearing mice in 6 h after either administration of endostar (200 μl) or saline (control group) and then biodistribution study was performed.Other 16 mice were divided into endostar treated group (20 mg/kg) and control group (saline) and then gamma imaging was performed in the two groups.Statistical significance of differences between the two groups was assessed using two-sample t test.Results Radiochemical purity of 99Tcm-HYNIC-2PEG4-Dimer was exceeded 95％.The expression of integrin αvβ3 in U87MG cell was high and gradually decreased after treatment with endostar.There was a negative dose-effect relationship between the dose of endostar and the expression of integrin αvβ3 with the peak effect at the dose of 400 μg/ml.The distribution study in vivo showed that the tracer uptake of U87MG tumors was high,but it decreased after injection of endostar.At 90 min,the ％ID/g of endostar and control groups were 1.50±0.08 and 6.27±0.33,respectively (t =40.23,P＜0.05).The average T/NT ratios of 99Tcm-HYNIC-2PEG4-Dimer uptake in the endostar and control groups were 1.02±0.11 and 2.58±0.36,respectively (t =10.25,P＜0.05).The integrin αv β3 positive expression ratios of tumor in endostar and control groups were (33.1 ±2.7) ％ and (81.5±3.2) ％,respectively (t =32.60,P＜0.05).Conclusions The novel probe 99Tcm-HYNIC-2PEG4-Dimer may be a promising radiotracer for integrin αvβ3-positive tumor imaging.It may be used for monitoring the therapeutic effect of endostar and may be potentially used for screening the candidates of anti-angiogenesis therapy.

Objective:To explore the clinical characteristics, diagnosis and treatment of acute leukemia patients during pregnancy.Methods:The clinical data of 16 cases with acute leukemia during pregnancy from January 2009 to December 2018 in the First Affiliated Hospital of USTC were retrospectively analyzed. The diagnosis and treatment regimens, pregnancy outcome, the early fetus and survival status of patients were also analyzed.Results:All 16 leukemia cases were confirmedly diagnosed and classified by bone marrow puncture, including 13 cases of acute myeloid leukemia (5 cases of non-acute promyelocytic leukemia and 8 cases of acute promyelocytic leukemia) and 3 cases of acute lymphoblastic leukemia. At the time of confirmed diagnosis, 6 patients were in first trimester, 6 cases in second trimester and 4 cases in late trimester. As for pregnancy outcome, 1 patient had natural birthing, 5 patients underwent cesarean operation, 9 patients underwent artificial abortion and 1 patient had spontaneous abortion. Chemotherapy was performed in 15 patients during pregnancy, 11 patients received chemotherapy for treatment of primary disease after pregnancy, 3 patients died during the treatment. During the follow-up of 13 cases, 8 patients survived and 5 patients lost follow-up.Conclusions:Early diagnosis of acute leukemia during pregnancy is very important. Bone marrow puncture should be performed timely to make clear diagnosis when blood routine result is abnormal during antenatal care. Multidisciplinary consultation should be initiated in time, and the best treatment plan should be worked out to guard against serious complications during pregnancy.

Objective:To assess whether air-charged urodynamic(ACC)can replace water-filled urodynamic(WFC)and the value of ACC for the diagnosis of benign prostatic hyperplasia(BPH)in these patients.Methods:In this prospective study, 27 male patients with BPH(aged 60-90 years)were randomly selected for WFC and ACC examinations during the same period to compare the values of urodynamic pressure parameters recorded for the two groups.Pressure values were compared using Bland-Altman plots and the paired sample t-test, and differences in abdominal pressure changes in the two groups were compared using the chi-square test. Results:Changes in WFC and ACC pressure values showed the same trends, but at the three points where data were recorded and compared, the mean abdominal pressure(Pabd), end of bladder filling pressure(Pves.fill)and maximum detrusor pressure(Pdet.void)were(25.3±8.5)cmH 2O(1 cmH 2O=0.098 kPa), (26.0±8.08.4)cmH 2O and(98.8±32.8)cmH 2O for WFC and(32.5, 5.5±5.3)cmH 2O, (32.6±5.0)cmH 2O and(95.3±36.3)cmH 2O for ACC, respectively, The pressure values of the two methods were significantly different( P<0.05). WFC pressure values were unstable, with 74.07%(20/27)showing a marked decrease during bladder filling, significantly different from those measured by ACC( P<0.001). Band-Altman plots illustrated high consistency between pressure values measured via WFC and ACC. Conclusions:The pressure measured by ACC does not represent that measured by WFC, suggesting a clinical need to establish standard reference data for ACC.The abdominal pressure instability measured by WFC may be one of the factors leading to different detrusor pressures from the two methods.The high consistency between pressure values from ACC and WFC indicates that the former can also be used to assess changes in bladder function in elderly BPH patients.

Hypothyroidism is a common adverse reaction in clinical multi-target tyrosine kinase inhibitor (TKI) and may be used as a predictor of efficacy of TKI drugs.Studies show that hypothyroidism is significantly associated with good prognosis in patients with renal cell carcinoma treated with multi-target TKI,which may be related to inhibition of vascular endothelial growth factor receptor pathway,potential off-target effects and inhibition of cell proliferation.Whereas in the patients with hepatocellular carcinoma who received multi-target TKI therapy,hypothyroidism is an indicator of poor prognosis,which is related to the T3/TR pathway regulating liver cancer growth and invasion.The predictive function and mechanism of thyroid hormone levels in different tumor patients receiving multi-target TKI drugs are different,and further research is still needed.

Objective To explore the pathogenesis of ovarian cancer by investigating the function of Toll-like receptor 1 (TLR1),TLR2 and TLR6 in peripheral blood mononuclear cell(PBMC) from patients with ovarian cancer.Methods PBMC,SK OV 3 co culture system and anti-TLR1,anti-TLR2,anti-TLR6 mAb blocking experiment were used to explore the relationship between TLR1,TLR2 or TLR6 signaling and inflammation in ovarian cancer.Quantitative real time PCR was used to measure interleukin(IL)-1β,IL-6,IL-8,and tumor necrosises factor(TNF)-α in the PBMC.MyD88,TRAF6,TANK,NF-κB and P-NFκB were observed by Western blotting.Results In the PBMC and SK-OV-3 coculture system,we found the activation of TLR signaling pathways,including significantly increased MyD88,TRAF6,TANK and P-NF-κB levels following cocultured with SK-OV-3 in PBMC from ovarian cancer patients.PBMC derived from ovarian cancer patients led to a increase in IL-1β,IL-6 and IL-8 mRNA levels after 24 hours of co-incubation with SK-OV-3 (Fold=1.74,Fold=1.92,Fold=1.65,P＜0.05),though there was no difference of TNF-a mRNA expression.In contrast to the ovarian cancer patients,coculture of PBMC derived from benign diseases controls and healthy normal controls decreased IL-1β at the mRNA level (Fold=0.71,P＜0.05;Fold=0.72,P＜0.05),furthermore the expression of MyD88,TRAF6,TANK,P-NF-κB,and NF-κB showed no changes.PBMC which treated with anti-TLR1,anti-TLR2 or-TLR6 mAb could inhibite inflammatory IL-1β (Fold=0.16,Fold=0.31,Fold=0.29,P＜0.05) and IL-6 (Fold=0.14,Fold=0.20,Fold=0.28,P＜0.05).Conclusion TLR1/TLR2/TLR6 in PBMC of ovarian cancer patients participate in the recognition of the factors.

Objective:To explore the effective method for treatment of small and short penis after hypospadias surgery.Method:s From November 2017 to November 2018, 57 children aged 4 to 14[mean age(7.91±2.89)years] with hypospadias who met the diagnostic criteria of small penis were reexamined at the First Affiliated Hospital of Xin-xiang Medical University.They were randomly divided into the physical treatment group and the drug treatment group according to the order of visits, and the untreated patients were included in the control group.Among them, 21 patients in the physical treatment group were treated with penile rehabilitation therapy apparatus, supplemented by Salvia mil-tiorrhiza bath (30 minutes/time, once/day, 10 days), and 20 patients in the drug treatment group were treated with Testosterone cream topically (3 times/day, 10 days). Penile relaxation length, stretch length, transverse and longitudinal diameters of glans in 2 groups before and after the treatment were measured.The relevant indexes of 16 patients in the control group measured before and after 10 days and compared with those in the treatment group.Result:s (1)The penile relaxation length in the physical treatment group increased from (25.48±6.13) mm to (30.72±6.49) mm, the length of stretch increased from (34.90±7.71) mm to (41.08±8.43) mm, the transverse diameter of glans increased from (14.81±3.40) mm to (16.57±3.42) mm, and the longitudinal diameter increased from (13.94±3.15) mm to (15.82±3.52) mm, and the differences were statistically significant (all P<0.05). (2)The penile relaxation length in the drug treatment group increased from (21.07±4.26) mm to (31.32±4.72) mm, the length of stretch increased from (31.94±7.96) mm to (45.39±7.24) mm, the transverse diameter of glans increased from (13.38±1.77) mm to (16.64±2.10) mm, and the longitudinal diameter increased from (13.09±1.77) mm to (16.62±1.86) mm, and the differences were statistically significant (all P<0.05). (3)There was no significant difference in penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans before and after 10 days in the control group (all P>0.05). (4) Compared with the control group, the penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans in the physical treatment group increased significantly, and the differences of growth values between the two groups were statistically significant (all P<0.05). (5) Compared with the control group, the penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans in the drug treatment group also increased significantly, and the difference of growth values between the two groups were statistically significant (all P<0.05). (6) The growth of penile relaxation length, the length of stretch and transverse and longitudinal diameters in the drug treatment group were higher than those in the physical treatment group, and the difference of growth values were statistically significant (all P<0.05). Conclusions:Both the negative pressure suction method and topical application of Testosterone cream are effective in the treatment of small and short penis after hypospadias surgery.However, Testosterone cream is difficult to obtain, and the treatment of negative pressure suction is simple, noninvasive, painless and free of adverse reactions.
