Injury to peripheral nerves can lead to neuropathic pain, along with well-studied effects on sensory neurons, including hyperexcitability, abnormal spontaneous activity, and neuroinflammation in the sensory ganglia. Neuropathic pain can be enhanced by sympathetic activity. Peripheral nerve injury may also damage sympathetic axons or expose them to an inflammatory environment. In this study, we examined the lumbar sympathetic ganglion responses to two rat pain models: ligation of the L5 spinal nerve, and local inflammation of the L5 dorsal root ganglion (DRG), which does not involve axotomy. Both models resulted in neuroinflammatory changes in the sympathetic ganglia, as indicated by macrophage responses, satellite glia activation, and increased numbers of T cells, along with very modest increases in sympathetic neuron excitability (but not spontaneous activity) measured in ex vivo recordings. The spinal nerve ligation model generally caused larger responses than DRG inflammation. Plasticity of the sympathetic system should be recognized in studies of sympathetic effects on pain.

ObjectiveTo compare the clinical effects and postoperative complications of microsurgical subinguinal varicocelectomy (MSV) with or without delivery of the testis and ligation of gubernacular veins in the treatment of varicocele.

METHODSWe retrospectively analyzed the clinical data about 163 varicocele patients treated by MSV, 40 with (group A) and the other 123 without delivery of the testis and ligation of gubernacular veins (group B). We compared the operation time, postoperative complications, rate of recurrence, and semen parameters before and at 3 months after surgery between the two groups of patients.

RESULTSThe operation time was significantly longer in group A than in B (［81.1 ± 20.0］ vs ［62.3 ± 9.6］ min, P = 0.041). Sperm concentration, total sperm count per ejaculate, sperm viability, and the percentage of progressively motile sperm were significantly improved in both groups at 3 months after MSV as compared with the baseline (P < 0.05). There were no statistically significant differences in the above semen parameters between the two groups of patients with grade Ⅲ varicocele before and after surgery (P < 0.05). Scrotal edema developed in 5 cases in group A and wound infection in 2 cases in group B after MSV, but no postoperative testicular atrophy or recurrence was observed in either of the two groups.

CONCLUSIONSMSV with delivery of the testis and ligation of gubernacular veins showed no advantages over that without in reducing varicocele recurrence and improving semen parameters, but rather involved longer operation time and a higher incidence rate of postoperative complications.

Cardiac dysfunction, a common consequence of sepsis, is the major contribution to morbidity and mortality in patients. Sodium tanshinone IIA sulfonate (STS) is a water-soluble derivative of Tanshinone IIA (TA), a main active component of Salvia miltiorrhiza Bunge, which has been widely used in China for the treatment of cardiovascular and cerebral system diseases. In the present study, the effect of STS on sepsis-induced cardiac dysfunction was investigated and its effect on survival rate of rats with sepsis was also evaluated. STS treatment could significantly decrease the serum levels of C-reactive protein (CRP), procalcitonin (PCT), cardiac troponin I (cTn-I), cardiac troponin T (cTn-T), and brain natriuretic peptide (BNP) in cecal ligation and puncture (CLP)-induced) septic rats and improve left ventricular function, particularly at 48 and 72 h after CLP. As the pathogenesis of septic myocardial dysfunction is attributable to dysregulated systemic inflammatory responses, several key cytokines, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10) and high mobility group protein B1 (HMGB1), were detected to reveal the possible mechanism of attenuation of septic myocardial dysfunction after being treated by STS. Our study showed that STS, especially at a high dose (15 mg·kg), could efficiently suppress inflammatory responses in myocardium and reduce myocardial necrosis through markedly reducing production of myocardial TNF-α, IL-6 and HMGB1. STS significantly improved the 18-day survival rate of rats with sepsis from 0% to 30% (P < 0.05). Therefore, STS could suppress inflammatory responses and improve left ventricular function in rats with sepsis, suggesting that it may be developed for the treatment of sepsis.

Objective: To determine the feasibility and short-term effect of single scrotal-incision orchidopexy (SSIO) without ligation of the processus vaginalis (PV) in the treatment of palpable undescended testis (PUDT). METHODS: This retrospective study included 109 cases of PUDT (125 sides) and 15 cases of impalpable undescended testis (IUDT). The former underwent SSIO without PV ligation (group A, n = 53) or standard inguinal orchidopexy with PV ligation (group B, n = 56) while the latter received laparoscopic exploration (group C). We analyzed the success rate of SSIO in the management of PUDT, postoperative complications, and incidence rates of hernia and hydrocele, and compared the relevant parameters between groups A and B. RESULTS: The median age of the PUDT patients was 1.4 (0.6－11.0) years. Group A included 24 cases of left PUDT (2 with hydrocele), 20 cases of right PUDT (1 with hydrocele), and 9 cases of bilateral PUDT, the success rate of which was 95.1%. Group B consisted of 27 cases of left PUDT, 22 cases of right PUDT (3 with hernias), and 7 cases of bilateral PUDT. The rate of PV patency in the PUDT patients was 80.8% (101/125). Laparoscopic exploration of the 15 IUDT patients revealed 2 cases of congenital testis absence, 6 cases of testis dysplasia, all treated by surgical removal, 3 cases of staying around the inner ring, descended by inguinal orchidopexy, and the other 4 treated by laparoscopic surgery. The incisions healed well in all cases, with no testicular atrophy, inguinal hernia or hydrocele. CONCLUSIONS Single scrotal-incision orchidopexy without PV ligation is a safe and feasible procedure for the treatment of palpable undescended testis, which avoids the risk of inguinal hernia or hydrocele.

Ischemic neurological injury is the most feared complication of spinal deformity surgery.In recent years, more attention has been paid to ischemic neurological injury during spinal deformity surgery including causes, risk factors, and prevention. The direct and indirect causes of ischemic neurological injury contains ligature of the segmental arteries, perioperative bleeding and excessive stretching or shortening of the spinal cord.Those patients at greatest risk for paraplegia following diagnosis of thoracic kyphosis or kyphoscoliosis, unilateral vessel ligation, perioperative hypotension, and extensive anterior and posterior surgery. Keeping reasonable mean arterial pressure and multimodal intraoperative monitoring may effectively prevent ischemic neurologic injury during surgery for spinal deformity.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.

METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.

RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).

CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.

OBJECTIVETo study the safety, effectiveness and feasibility of suprapubis-assisted umbilical laparoendoscopic mini-dual-site surgery (SAU-LEMDS) in the treatment of varicocele.

METHODSThis study included 80 varicocele patients aged 24 - 44 (mean 28.5 +/- 2.6) years, 25 cases of grade I, 45 cases of grade II and 10 cases of grade III, 58 cases in the left side, 6 in the right and 16 in both sides, and all with asthenospermia. The patients were treated by SAU-LEMDS under subarachnoid anesthesia combined with general anesthesia in a supine position with a head-down-feet-up slope of 15 degrees. Two 5 mm trocars were inserted bilaterally at the umbilical edge, one with a 5 mm 30 degrees laparoscope placed in it, and another into the abdominal cavity below the pubic hairline with a 5 mm laparoendoscopic clipper placed in it. The operation procedure was similar to that of standard laparoscopic ligation of spermatic veins, with reservation of the spermatic artery and double-ligation of spermatic veins. And the procedure was repeated for the contralateral lesion in the bilateral cases. Postoperative follow-up was conducted for the incidences of orchiatrophy and testicular hydrocele and changes of seminal parameters.

RESULTSAll the operations were successful, with the mean operation time of (10 +/- 5.0) min (range 8 to 25 min) for the unilateral cases and (18 +/- 6.5) min (range 15 to 30 min) for the bilateral cases, the mean blood loss of (1.5 +/- 0.5) ml (range 1 to 2 ml), and the mean postoperative hospital stay of (2 +/- 0.5) d (range 1.5 to 3 d). The patients were followed up for 6 -24 (12 +/- 2.5) months, which showed significant improvement in sperm motility as compared with the baseline ([28.53 +/- 5.21] vs [19.62 +/- 3.56]%, P < 0.05), with 28 cases (35.0%) restored to normal. Recurrence was found in 4 cases (5.0%). Testicular hydrocele occurred in 7 cases (8.75%), but orchiatrophy in none. The scars in the umbilicus and suprapubis were invisible because of the wrinkles and pubic hair.

CONCLUSIONSAU-LEMDS is safe, effective and feasible for the treatment of varicocele. It is superior to umbilical laparoendoscopic single-site surgery (U-LESS) for its less invasiveness, simpler operation, and better cosmetic appearance.

OBJECTIVETo investigate the prevention and treatment of complications during and after endoscopic mucosal band ligation (EMBL) for precancerous lesions and early cancer in the esophagus.

METHODSClinical data of 47 patients with esophageal precancerous lesions and early cancer undergoing EMBL in our center from June 2011 to August 2013 were reviewed retrospectively. Complications and associated treatment during operation, after operation and during follow-up were analyzed.

RESULTSComplications during operation included 7 cases of bleeding (14.9%) and 1 case of perforation (2.1%), who received hot biopsy forceps and argon plasma coagulation to stop bleeding successfully, and titanium clamp to suture wound surface. No cutaneous emphysema and pneumothorax occurred. Complications after operation included 1 case of delayed bleeding (2.1%) who received blood stopping under gastroscope, 2 cases of mediastinal and subcutaneous emphysema (4.3%), 6 cases of pleural effusion (12.8%), and 5 cases of minor inflammation or segmental atelectasis of pulmonary (10.6%), who all received successful conservative treatment. Seven cases of esophageal stricture occurred during follow-up, who were improved by balloon dilatation and metal-film stent placement. No deaths associated with EMBL occurred. All the complications were cured through conservative treatment. No additional surgery associated with the complications was needed. Post-operative pathology revealed 1 case was chronic inflammatory hyperplasia, 11 were low-grade intraepithelial tumor, 15 were high-grade intraepithelial tumor, 8 were carcinoma in situ, 12 were squamous cancer (8 with invasion into mucous muscular layer, 4 into submucous layer). Only 1 case of submucous cancer needed transthorax esophageal cancer radical operation because of dangerous margin. No relapse case was found during followed-up.

CONCLUSIONEMBL can treat the esophageal precancerous lesions and early esophageal cancer effectively and its complications can be managed with conservative therapy usually.

OBJECTIVETo compare the outcomes of the three microsurgical strategies, inguinal high ligation (IHL), retroperitoneal high ligation (RHL) and low ligation (LL) of internal spermatic veins, in the treatment of varicocele.

METHODSWe retrospectively analyzed 120 cases of varicocele, which were equally divided into groups I , II and III to be treated by IHL, RHL and LL of internal spermatic veins, respectively. We compared the operation times, post-operative complications, recurrence rates and results of pre- and post-operation semen analysis among the three groups.

RESULTSThe mean operation time was significantly longer in group III ( [55 +/- 6 ] min) than in I ([35 +/- 10] min) and II ([42 +/- 12] min) (P<0.05), while the rate of post-operative complications remarkably higher in group I (4 cases of hydrocele [10% ] and 3 cases of epididymitis [7.5%]) than in II (2 cases of hydrocele [5%] and 2 cases of epididymitis [5%]) and III (1 case of hydrocele [2.5%] and 1 case of epididymitis [2.5%]) (P<0.05). Six to 12 (mean 9) months of follow-up visit found 2 cases (5% ) of recurrence in group I, 1 case (2.5%) in group II and none in group III, with no statistically significant difference among the three groups (P>0.05). At 12 months after surgery, group III showed significantly higher sperm concentration, grade a +b sperm and the sperm motility than the other two (P<0.05), but no significant differences were observed in these parameters among the three groups preoperatively.

CONCLUSIONAs a microsurgical approach to the treatment of varicocele, LL is better than IHL and RHL of internal spermatic veins in improving the seminal parameters of the patients.
