OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.

METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.

RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.

CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.

OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.

OBJECTIVE: To investigate the relationship between platelet activating factor (PAF) and occurrence of hepatorenal syndrome (HRS). METHODS: A total of 57 cases of patients with liver cirrhosis or hepatitis gravis were enrolled. The serum concentrations of PAF, lipopolysaccharide (LPS) and prothrombin activity (PTA), total bilirubin, and serum creatinine were detected in patients combined with HRS and in patients without HRS in hospital at the term. The correlations among the PAF, LPS, and the function of liver and kidney were analyzed. RESULTS: The concentrations of PAF and LPS in the patients combined with HRS were significantly higher than those patients without HRS. There were linear correlations between the PAF and LPS level, the total bilirubin level and PAF level, the PAF level and serum creatinine level. CONCLUSION The PAF associates with the occurrence of HRS. The PAF may mediate the occurrence of HRS induced by LPS. The PAF level may forecast whether patients with liver failure will take place HRS.

OBJECTIVETo observe the effect of Pinggan Qianyang Recipe (PQR) on inhibiting angiotensin II (Ang II) induced proliferation and migration of vascular smooth muscle cells (VSMCs) and changes of DNA methylation.

METHODSVSMCs were cultured using tissue explant method, and PQR containing serum was prepared. Primarily cultured VSMCs were divided into four groups, the normal group, the model group, the folate group (folic acid intervention) , and the PQR group. The proliferation and migration of VSMCs was duplicated by Ang II. After 24-h Ang II induced culture, 40 microg/mL folic acid was added to the folate group for 48 h, while 5% PQR containing serum was added to the PQR group for 48 h. The cell growth curve of VSMCs was drawn by using Cell Counting Kit (CCK-8). The proliferative activity of VSMC was determined by MTT assay. The migration of VSMCs was measured by Millicell chamber. The general level of cytosine methylation in cell nucleus was detected via 5-mC antibodies immunofluorescence, and mRNA expression levels of DNA methyltransferase 1 (DNMT1) were measured by Real-time q-polymerase chain reaction (q-PCR).

RESULTSVSMCs were promoted by Ang II at 10(-6) mol/L for 24 h. Compared with the normal group, the proliferative activity and migration quantity of VSMCs obviously increased, and DNA methylation level obviously decreased (P < 0.05, P < 0.01). Compared with the model group, the cell growth, proliferative activity and migration quantity of VSMCs obviously decreased and the general DNA methylation level increased in the folate group and the PQR group (P < 0.05, P < 0.01). Compared with the normal group, the mRNA expression of DNMT1 decreased in the model group (P < 0.01). Compared with the model group, mRNA expression of DNMT1 in Ang II induced VSMCs was obviously enhanced in the folate group and the PQR group (P < 0.01).

CONCLUSIONSPQR could inhibit Ang II induced proliferation and migration of VSMCs, and cause high genomic DNA methylation level. Changes of DNA methylation might be associated with DNMT1 expression.

OBJECTIVETo introduce the procedure of the 1st ray stabilization combined with resection of the lesser metatarsal heads for patient with severe forefoot deformity caused by rheumatoid arthritis (RA) and evaluate the short to mid-term clinical results.

METHODSFrom Oct. 2006 to Aug. 2010,97 patients (129 feet) aged from 36 to 67 years (average 54), with forefoot deformity caused by rheumatoid arthritis were reviwed. There were 88 males and 9 females,65 single lateral involved and 32 bilateral involved, the average duration of disease was 17 years (6 to 32 years). The 1st ray instability and lesser metatarsophalangeal (MTP) joint stiff dislocation were found in all cases. The first ray stabilization combined with resection of the lesser metatarsal head procedure were performed for all cases. The radiographic Hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measurde and the JSSF (Japanese Society for Surgery of the Foot) score were evaluated before operation and every follow up.

RESULTSThe average followed-up was 37 months (6 to 52 months) for all patients except 5 (7 feet) and 1 died for acute cardiac infarction 1 year after operation. The average JSSF score improved from (33.2 +/- 8.2) points preoperative to (67.3 +/- 3.1) points at final followed-up (P < 0.01); the average HVA was corrected from (50.0 +/- 11.8) degrees preoperative to (21.2 +/- 3.2) degrees at final follow up (P < 0.01); the average IMA was corrected from (15.5 +/- 3.6) degrees preoperative to (9.7 +/- 6.6) degrees at final follow up (P < 0.01). MTP joint nonunion was found in 4 feet. A radiographic high density mass was found in the 1st cuneiform bone during 8 to 11 months followed-up in 3 feet; delayed wound healing was happened in 9 feet; MTP joint infection was happened in 2 feet; tarsometatarsal joint infection was happened in 1 foot; lesser MTP joints deformity recurrence were found in 16 feet.

CONCLUSIONThe characters of forefoot with RA in later stage are the 1st ray deformity and instability compound with the lesser toes deformity. The 1st ray stability procedure which include the 1st MTP arthrodesis and the Lapidus procedure can correct the 1st ray deformities and rebuilt its stability. The lesser toes metatarsal head resection is effective in correct their deformity. This combined procedure is reliable. It is suitable for patients with severe Hallux valgus, increased IMA, tarsometatarsal joint instability and the lesser MTP joint stiff dislocation.

OBJECTIVETo study the effects of desmopressin (DDAVP) on coagulation factor Ⅷ (FⅧ) and activated partial thromboplastin time (APTT) in children with mild hemophilia A.

METHODSEighteen children with mild hemophilia A were enrolled. DDAVP (0.3 μg/kg•d) was injected intravenously for 5 days. Plasma FⅧ levels and APTT were measured before and after DDAVP treatment.

RESULTSIn 16 of 18 children with mild hemophilia A, the bleeding symptoms, including the articular or musclar hematoma, were significantly alleviated as a result of DDAVP treatment. The plasma FⅧ levels increased significantly to (27±4)% and APTT was shortened to (66±10)s 60 minutes after the first dose of DDAVP treatment. The plasma FⅧ remained at the levels of 25%-30% during 3-4 days of DDAVP treatment. Five days after DDAVP treatment, the plasma FⅧ levels decreased [(21±3)%], and APTT was prolonged when compared with 1-4 days of DDAVP treatment.

CONCLUSIONSDDAVP treatment can increase plasma FⅧ levels and shorten APTT in children with mild hemophilia A. DDAVP is effective in the treatment of mild hemophilia A. The duration of DDAVP therapy for mild hemophilia A is recommended as 3 to 4 days.
