OBJECTIVETo compare the efficiency difference in chronic orchialgia between electroacupuncture and western medicine and explore the better therapy for chronic orchialgia.

METHODSEighty-six cases of chronic orchialgia were randomly divided into an electroacupuncture group (56 cases) and an Indomethacin group (30 cases). Except the conventional oral administration of Amitriptyline for anti-depression, electroacupuncture was applied at Shenshu (BL 23), Ciliao (BL 32), Sanyinjiao (SP 6), Taichong (LR 3) and others in electroacupuncture group, and Indometacin suppository anal therapy was used in Indometacin group. The session of treatment in two groups was 2 weeks. Before and after treatment, pain number assessment scale was adopted for the assessment of pain severity separately to compare the differences in pain score on 3rd, 7th, 10th and 14th days after treatment.

RESULTSThe pain score at each time point was improved remarkably as compared with that before treatment in two groups (P < 0.05, P < 0.01). In comparison on the 7th, 10th and 14th days of two groups, the pain scores in electroacupuncture group was lower than those in Indometacin group (all P < 0.05).

CONCLUSIONElectroacupuncture combined with Amitriptyline treatment is quite effective on chronic orchialgia, which is superior to the effect of Indo methacin combined with Amitriptyline treatment and deserves to be promoted in application.

Chronic orchialgia (CO) is a common complaint in urology or andrology. Due to its complicated pathogenesis, the diagnosis and treatment of CO are quite challenging. Based on different etiologies, CO can be idiopathic or secondary. Idiopathic CO accounts for approximately 50% of the cases and is probably associated with Wallerian degeneration in the spermatic cord nerves and peripheral sensitization. Secondary CO can be attributed to direct causes and its treatment focuses on the pathologic condition identified. The main methods for the treatment of CO include conservative and surgical strategies, among which microsurgical spermatic cord denervation ( MSCD) is an effective and minimally invasive option, while orchiectomy is but the last alternative when no other means is left.

OBJECTIVETo explore the clinical types, prevention and treatment of testicular and epididymal diseases in the Tibetan area.

METHODSWe retrospectively analyzed the clinical data of 105 cases of testicular or epididymal diseases treated in our department from 2007 to 2009. All the patients were permanent inhabitants in Tibet.

RESULTSAmong the 105 patients, the main types of testicular and epididymal diseases were tuberculosis (27 cases) and tumor (21 cases). And 99% of the patients were Tibetan farmers and herdsmen.

CONCLUSIONTibetan farmers and herdsmen have a poor knowledge about testicular and epididymal diseases and their prevention and treatment. Clinicians and related institutions need to strengthen health education on these diseases in Tibetan area to improve the early awareness, early diagnosis, early prevention and early treatment of testicular and epididymal diseases.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis and treatment of primary testicular yolk sac tumor (YST).

METHODSWe studied 8 cases of primary testicular YST by microscopy and immunohistochemistry.

RESULTSThe 8 cases of primary testicular YST, including 2 consultation cases, were confirmed from 1998 to 2013, accounting for 10.7% (8/75) of all the testicular germ cell tumors diagnosed in our hospital. The patients ranged in age from 7 to 43 years, 23.9 years on average. The main clinical manifestation of the patients was painless unilateral testis swelling. Microscopically, reticular tissues, schiller-duvaI (S-D) bodies, and eosin-stain transparent bodies were seen in the tumors. One of the cases was confirmed to be simple YST, while the other 7 mixed YST. AFP was a characteristic immunophenotype marker of the tumors.

CONCLUSIONPrimary testicular YST is a rare malignancyr with poor prognosis. Its diagnosis depends on preoperative AFP test and postoperative pathology. Comprehensive treatment, including orchiectomy, chemotherapy, and radiotherapy, can prolong the survival of the patients.

OBJECTIVETo investigate the preventive effect of antioxidant and calcium channel blockade on testicular fibrosis in rats, and to explore the ideal drug for preventing it.

METHODSEighty Wistar rats were divided into a control group (Group A, n = 10), a treatment group (Group B, n = 57) and a testicular fibrosis model group (Group C, n = 13). And the treatment group was further divided into a higher dosage group (Group a, n = 20), a medium dosage group (Group b, n =20) and a lower dosage group (Group c, n = 17). Testicular fibrosis was duplicated with altered Wang Tao's method. From the second day of the first immunization, the higher dosage group was given antioxidant vitamins 90 mg/(kg x d) and verapamil 50 mg/(kg x d), the medium dosage group antioxidant vitamins 90 mg/(kg x d) and verapamil 25 mg/(kg x d), and the lower dosage group antioxidant vitamins 90 mg/(kg x d) and verapamil 12.5 mg/(kg x d), all for 150 days. The control and the model groups received no treatment. The sperm count, sperm deformity rate, testis length and seminiferous tubule intradiameter were measured, and the changes of the testis interstitial substance and spermatogenic cells were observed by light microscope and transmission electron microscope.

RESULTSTesticular fibrosis was significantly prevented by the higher- and medium-dosage treatment in the rats. In the higher dosage group, the intradiameter of the seminiferous tubules and the thickness of the limiting membrane were almost the same as in the control. In the lower dosage group the thickness of the limiting membrane was thicker and the damage to the spermatogenic cells was heavier than in the control, but the pathological changes of the testis structure was lighter than in the model group, in which Hyperplasia and fibroblast increase in the interstitial substance were significant, interstitial mast cells and peritubular mast cells increased, the thickness of the limiting membrane of the seminiferous tubules seriously thickened, and the damage to the spermatogenic cells was severe.

CONCLUSIONTesticular fibrosis in rats can be significantly prevented by antioxidant and calcium channel blockade.

OBJECTIVETo investigate the action of nitric oxide (NO) on testicular dysfunction in cirrhotic rats.

METHODSCirrhotic rats were induced by bile duct ligation (BDL). Concentration of NO in the serum and homogenates of the testicular tissue in biliary cirrhotic rats, L-NAME rats, and sham operated rats were measured by assay of nitrate reductase. Concentrations of testosterone in the serum of 3 groups were measured by radioimmunoassay. Sperm density and percent of motive sperm in the epididymis of the rats were determined.

RESULTSConcentrations of NO in the serum and homogenates of the testicular tissue of cirrhotic rats were significantly greater than those of sham operated rats (4.165 micromol/L 1.162 micromol/L, and 1.305 micromol/g 0.087 micromol/g vs 0.535 micromol/L 0.237 micromol/L and 0.720 micromol/g 0.063 micromol/g). Concentrations of testosterone in the serum, the sperm density and percent of motive sperm in the epididymis were significantly lower in cirrhotic rats than sham operated rats (0.049mug/L 0.020 microgram/L, 16.46% 4.84%, and 86.89 10(6)/ml 33.17 10(6)/ml vs 2.680 microgram/L 0.403 microgram/L, 62.45% 9.21%, and 299.43 10(6)/ml 53.85 10(6)/ml). By contrast, the administration of a low dose of L-NAME (0.5 mg/kg per day) for one week to cirrhotic rats was associated with a significant reduction in concentration of NO (1.975 micromol/L 0.406 micromol/L and 0.950 micromol/g 0.057 micromol/g) and a significant increase in concentration of testosterone in the serum, the sperm density and percent of motive sperm in the epididymis (0.993 microgram/L 0.179 microgram/L, 33.85% 4.93%, and 188.94 10(6)/ml 38.34 10(6)/ml).

CONCLUSIONSNO is associated with testicular dysfunction in cirrhosis. The testicular dysfunction induced by cirrhosis can obtain improvement by using low dose of L-NAME.

OBJECTIVETo study the effect of resveratrol on spermatogenesis after 2,5-hexanedione(2,5-HD)-induced testicular injury.

METHODSForty male SD rats were randomly divided into 5 groups. Group A were normally raised and Group B, C, D and E exposed to 1% 2,5-HD for 5 weeks, followed by administration of resveratrol of different concentrations (20, 40 and 80 mg/[ kg x d], respectively) to Group C, D and E for 9 weeks. Then the rats were killed, their physical signs, body weight gain and testis weight were assessed, and immunohistochemistry and Western blot analysis used to investigate the numbers and diameters of seminiferous tubules and the expression of c-kit protein of spermatogenic cell membrane.

RESULTSThe rats exposed to 2,5-HD showed weak body, lax skin, dim color pattern, tardy body weight gain, and emaciated testis. Immunohistochemistry revealed emaciated seminiferous tubules, stagnant obsolete spermatogonia and negative expression of c-kit protein. After resveratrol administration, the 2,5-HD-induced physical signs were improved and close to normal. Compared with those of the 2,5-HD injured group, the body weight and testis weight of the resveratrol treated group increased obviously (P < 0.01); and the aliquots of the seminiferous epithelia began to differentiate and the spermatogenesis and expression of c-kit protein partly resumed (P < 0.01). With increasing dose of resveratrol, the diameters and numbers of seminiferous tubules (P < 0.01) and the expression levels of c-kit protein (P < 0.01) were gradually and significantly restored almost to normal.

CONCLUSIONResveratrol could promote the recovery of spermatogenesis after 2,5-HD-induced testicular injury.
