OBJECTIVETo investigate the clinical effect of microsurgical vasoepididymostomy and/or vasovasostomy in the treatment of obstructive azoospermia.
METHODSThis study included 76 patients with obstructive azoospermia, 53 treated by bilateral vasoepididymostomy (8 involving the epididymal head, 18 involving the epididymal body, 5 involving the epididymal tail, and 22 involving the epididymal head, body and tail), 14 by unilateral vasoepididymostomy, and the other 9 by unilateral vasoepididymostomy + unilateral vasovasostomy (including cross anastomosis). We followed up the patients for 2 to 16 months for the patency rate, routine semen parameters, and pregnancy outcomes.
RESULTSThe success rate of bilateral vasoepididymostomy, unilateral vasoepididymostomy, and unilateral vasoepididymostomy + unilateral vasovasostomy (including cross anastomosis) were 62.26% (33/53), 35.71% (5/14), and 77.78% (7/9), respectively. The average sperm concentrations in the three groups of patients were (27.9 +/- 5.74), (11.8 +/- 8.33), and (19.9 +/- 7.53) x 10(6)/ml, the average total sperm counts were (65.6 +/- 13.71), (28.0 +/- 15.86), and (69.2 +/- 28.59) x 10(6), and the mean rates of progressively motile sperm were (22.3 +/- 3.18), (11.0 +/- 9.77), and (15.8 +/- 5.05)%, respectively. The success rates of bilateral vasoepididymostomy that involved the epididymal head, body, tail, and all the three parts were 62.5, 72.22, 60, and 54.55%, respectively. Natural pregnancy was achieved in 8 (10.53%) of the total number of cases.
CONCLUSIONMicrosurgery is effective for the treatment obstructive azoospermia. Unilateral vasoepididymostomy + unilateral vasovasostomy is superior to the other procedures, followed by bilateral vasoepididymostomy. Bilateral vasoepididymostomy involving the epididymal body may achieve a slightly better effect than that involving the other epididymal parts.

OBJECTIVETo explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC).
METHODSThe complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on.
RESULTSThe TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05).
CONCLUSIONSCFC is featured as complex syndromes. The most common complex syndromes were qi deficiency complicated qi stagnation syndrome and qi deficiency complicated blood deficiency syndrome. Basic syndrome related factors such as age, engaged professionals, sleep quality, poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation were associated with the distribution of CFC syndromes.

This study is to investigate the antitumor activity of CIP-36 on multidrug resistant human oral squamous carcinoma cell line (KBV200 cells) in vitro and the possible anticancer mechanisms. MTT assay, Hoechst fluorescein stain, RT-PCR and immunohistochemistry were carried out on KBV200 and KB cells. The growth of many tumor cells was obviously inhibited by CIP-36, especially the multidrug resistant cells KBV200. Obvious apoptosis could be observed in the Hoechst 33342 staining experiments. The results of RT-PCR showed that the levels of p53, p21, caspase-3 and bax mRNA increased, and meanwhile the expression of mdr-1 and bcl-2 mRNA decreased in a dose-dependent manner. The data were significantly different from that of vehicle. The expression of P-gp significantly decreased with the increasing dosage of CIP-36 examined by immunohistochemistry. It can be concluded that CIP-36 could change resistance-related genes and proteins to overcome multidrug resistance in the KBV200 cell line.

OBJECTIVETo investigate the efficacy of the procedure for prolapse and hemorrhoids (PPH) combined with external hemorrhoids excision in the treatment of III or IV mixed hemorrhoids.
METHODSOne hundred and twelve patients with III or IV mixed hemorrhoids admitted for surgical treatment were randomly divided into three groups: PPH 1 group (34 cases), PPH2 group (36 cases), and Milligan-Morgan group (42 cases). PPH1 group received the standard PPH operation, PPH2 received PPH and external hemorrhoids excision, and Milligan-Morgan group received Milligan-Morgan hemorrhoidectomy. Postoperative 24 h-pain index, pain index when defecating, bleeding, anal discomfort feeling , wound edema, the ability of controlling feces, operating time, hospitalization time and charges were recorded. The change of anal dynamics was detected by anorectal manometry. All the patients were followed-up for 0.5-1 year.
RESULTSThere were no significant differences among the three groups in bleeding, anal discomfort feeling, the ability of controlling feces (P>0.05). The postoperative 24 h-pain index of PPH1 group was lower than those of the other two groups (P<0.05). PPH1 group and PPH2 group were better than Milligan-Morgan group in pain index when defecating, wound edema, operating time, and hospitalization time (P<0.05). Milligan-Morgan group was better than the other two groups in postoperative urinary retention and hospital charges (P<0.05). The change of anal duct pressure of Milligan-Morgan group was less than those of the other two groups (P<0.05). Within 0.5-1.0 year follow-up, 3 patients got thrombosed external hemorrhoid in PPH1 group, 2 patients recurred and 1 patient got thrombosed external hemorrhoid in Milligan-Morgan group, no recurred patients in PPH2 group.
CONCLUSIONPPH combined with external hemorrhoid excision is a safe and effective treatment for mixed hemorrhoids, which is suitable for mixed hemorrhoids with severe external hemorrhoids.

OBJECTIVESome research has shown that learning and memory function impairments in rats with hypothyroidism are associated with triiodothyronine (T3) deficiency in neurons. This study aimed to investigate the effects of L-T3 administration on learning and memory behaviors in neonatal mice with excitotoxic brain damage.
METHODSSeventy-one 5-day-old ICR neonatal mice were randomly assigned to five groups: controls that received intracerebral and intraperitoneal injections of phosphate buffered saline (PBS) (n=14); a group that received intracerebral injections of ibotenic acid (IA) and intraperitoneal injection of PBS (n=14); 3 groups that received intracerebral injections of IA and intraperitoneal injection of L-T3 at 0.2, 0.5, and 1 microg/kg, respectively (n=14-15). Intraperitoneal injections were done 1, 24, 48, 72 and 96 hrs after intracerebral injections. Learning and memory functions were evaluated by the Y-maze discrimination learning test on postnatal days 33-34.
RESULTSThe learning and memory functions in the highest L-T3 dose group were significantly better than those in the IA, and the lower L-T3 dose groups, presenting with decreased number of trials to criterion[15.8 + or - 4.5 vs 21.3 + or - 6.3 (IA group), 20.5 + or - 6.0 (0.2 microg/kg L-T3 group) or 21.0 + or - 6.5 (0.5 microg/kg L-T3 group); P<0.05], and achieving a higher correct percentage [91.4+ or - 9.5% vs 79.3 + or - 10.0% (IA group), 77.9 + or - 14.2% (0.2 microg/kg L-T3 group) or 80.7 + or - 12.2% (0.5 microg/kg L-T3 group); P<0.05].
CONCLUSIONSHigh-dose L-T3 (1 microg/kg) may improve learning and memory functions in mice following excitotoxic brain damage.

This study is to investigate the effect of ferulic acid on learning and memory impairments of vascular dementia (VD) rats and its mechanism of action. VD rats model was replicated by permanent bilateral common carotid artery occlusion (2VO). The learning and memory capability of VD rats was evaluated by Morris water maze. The activity of acetylcholinesterase (AChE) and superoxide dismutase (SOD) and the content of glutamic acid (Glu) and malondialdehyde (MDA) in hippocampus of VD rats' brain were determined, separately. The results showed that ferulic acid could alleviate learning and memory deficits of VD rats significantly. Ferulic acid was found to inhibit the activity of AChE and increased the activity of SOD in rat hippocampus. In addition, ferulic acid could also decrease the content of Glu and MDA in rat hippocampus. These results suggested that ferulic acid could alleviate VD rats' learning and memory deficits, which might be due to antioxidation, the improvement of cholinergic system in brain, or the inhibitory of nerve injury by excitatory amino acids.

This work was performed to determine the role of delta-opioid receptor (DOR) in protection against acute ischemia/reperfusion injury. Transient (1 h) focal cerebral ischemia was induced by middle cerebral artery occlusion (MCAO). DOR agonist TAN-67 (30 nmol, 60 nmol, 200 nmol), DOR antagonist naltrindole (20 nmol, 50 nmol, 100 nmol) or artificial cerebral spinal fluid (aCSF) was injected respectively into the lateral cerebroventricle of the rat 30 min before the induction of brain ischemia. Neurological deficits were assessed by the five-grade system (Longa's methods). The brain infarct was measured by cresyl violet (CV) staining and infarct volume was analyzed by an image processing and analysis system. The expression of DOR was detected by Western blot. The results showed that 60 nmol TAN-67 significantly reduced the infarct volume (P<0.05), attenuated neurological deficits (P<0.05) and tended to increase the expression of about 60 kDa DOR protein (P>0.05), while 100 nmol naltrindole aggravated ischemic damage and decreased about 60 kDa DOR protein expression (P<0.05). These results suggest that DOR activation protects the brain against acute ischemia/reperfusion injury in rat.
