Objective:To analyze the early and middle term clinical effects of mitral valve repair in children with mitral insufficiency.Methods:From January 2012 to January 2019, a total of 202 cases of children with mitral insufficiency treated by mitral valve repair were selected from the department of cardiothoracic surgery of Nanjing Children's Hospital, patients with atrioventricular septal defect, single ventricle and ischemic mitral regurgitation were excluded. Echocardiography was used to compare the preoperative and postoperative left ventricular function and degree of regurgitation in children to evaluate the early and middle term efficacy of mitral valvuloplasty.Results:There were 5 cases of early death(5/202, 2.5%) and 3 cases of late death(3/202, 1.5%). The mean follow-up time was(19.49±17.48) months(1-68 months). Postoperative echocardiography showed that the left heart function and mitral regurgitation were significantly improved.Conclusion:Mitral valvuloplasty can significantly correct mitral insufficiency in children, and it has satisfactory mid-term efficacy and good clinical value.

Objective To investigate the clinical efficacy of intraluminal enucleation in transurethrat vapor- ization and electro-reesection of the prostate.Methods A retrospective analysis was reviewed in 62 case of prostatic hypertrophy,which were treated with intraluminal enucleation in vaporization of prostate.All pacients had a sucessful operation.There were 12 case in unipolar vaporization and 50 in plasmakenitic bipolar vaporization.Results Opera- tion time ranged from 50 to 162 minutes,with an average of 76min.Bleeding ranged from 40 to 200 ml,with an av- erage of 110ml.There was no blood transfusion.The weight of prostate was 62～138g,the catheter was maintained for 3～5 days postoperatively.The hospital stay was 7～10 days,average 8 days.All patients were cured.There was a fllow-up for 1～20 months,with an average of 8 months.The IPSS decreased by 22 points on average,and peak urine flow(Qmax)increasd to(16.8?3.3)ml/s.There wre no urethralstricture,permanent urinary incontinence, TURS,postoperative hemorrhage,retrograde ejaculation and recurrence.Conclusions Intraluminal enucleation in treatment of prostalic hypertroply is a new,safe,and effective method,which should be popularized in clinical prac- tice.

AIM:To understand the clinic effect of intravitreal anti-vascular endothelial growth factor(VEGF) drugs injection in the treatment of fundus disease in the real-world study (RWS).METHODS:The clinical cases treated with anti-VEGF drugs in our department from September 2012 to June 2015 were enrolled in this study.Retrospective investigation was reviewed to the kinds of diseases, frequency, usage, efficacy, adverse reaction, and the effects on visual acuity, fundus and macular thickness which were treated with intravitreal anti-VEGF drugs injection.RESULTS:In 305 patients (340 eyes) treated with anti-VEGF drugs, 53 patients (60 eyes, 17.6%) were wet age-related macular degeneration (AMD), polypoidal choroidal vasculopathy (PCV) 16 cases (18 eyes, 5.3%), diabetic macular edema (DME) 120 cases (134 eyes, 39.4%), branch retinal vein occlusion (BRVO) secondary macular edema 61 cases (68 eyes, 20.0%), central retinal vein occlusion (CRVO) secondary macular edema 29 cases (32 eyes, 9.4%), idiopathic choroidal neovascularization (ICNV) 16 cases (18 eyes, 5.3%), high myopia with choroid neovascularization 4 cases (4 eyes, 1.2%), neovascular glaucoma 4 cases (4 eyes, 1.2%), retinal angiomatous proliferation (RAP) 1 cases (1 eyes, 0.2%) and optic papillary neovascularization 1 cases (1 eyes, 0.2%).The minimum age was 16 years old, and the maximum age 90 years old.There were 247 cases (275 eyes, 80.9%) were treated with intravitreal ranibizumab injection, 58 cases (65 eyes, 19.1%) intravitreal conbercept injection.The time number of all patients accepted anti-VEGF drugs treatment was 465, with an average of 1.7 times per eye.Which, the 3 + PRN treatment method in 98 patients (109 eyes, 32.1%), 1 + PRN treatment in 207 patients (231 eyes, 67.9%).69 cases (77 eyes, 22.6%) were used alone to receive anti-VEGF drugs therapy, 10 cases (11 eyes, 3.2%) combined with intravitreal triamcinolone injection(TA), 35 cases (39 eyes, 11.5%) combined with vitrectomy, 26 cases (29 eyes, 8.5%) combined with photodynamic treatment (PDT), 165 cases (184 eyes, 54.1%) combined with simple laser treatment.After anti-VEGF drug treatment, majority of patients' the best corrected visual acuity (BCVA), fundus and central macular thickness(CMT) were significantly improved, compared with the pre-treatment, the difference is significant (P<0.05).So that anti-VEGF drugs can effectively improve visual function and ocular fundus for fundus diseses.There were no serious adverse reactions except 3 patients appearling skin redness, itching, rash, 1 patient low low-grade fever and 1 patient acute cerebral infarction during the treatment.CONCLUSION:Intravitreal anti-VEGF drugs injection can significantly improve the visual function and ocular fundus for patients with fundus diseases, but there are still some adverse events, which should be attached great importance to medical workers.

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.

Serum levels of soluble MHC class I-related chain A (sMICA) are related with the prognosis of various types of cancer; however, few studies on the prognostic value of sMICA in hepatocellular carcinoma (HCC) have been reported. In this study, we retrospectively investigated the relationship between sMICA levels and clinical features of advanced HCC, and we assessed the prognostic value of sMICA in advanced HCC. Furthermore, the relationship of serum sMICA levels and natural killer group 2, member D (NKG2D) expression on natural killer (NK) cells was also evaluated. We detected sMICA levels in the serum of 60 advanced HCC patients using enzyme-linked immunosorbent assay (ELISA) and measured expression levels of NKG2D on NK cells using flow cytometry. We found that serum sMICA levels in HCC patients were in the range of 0.10-6.21 ng/mL. Chi-square analyses showed that sMICA level was significantly related with only tumor size. Survival analysis showed that a high sMICA level was significantly related with poor prognosis among HCC patients. Multivariate analyses indicated that sMICA was an independent prognostic factor. In addition, the levels of CD56+NKG2D+ NK cells were within the range of 11.2%-55.4%, and correlation analyses indicated that sMICA level was negatively correlated with the level of NKG2D+ NK cells. Our results suggest that serum sMICA levels may be an independent prognostic factor for advanced HCC.

Objective To analyze the operation of long-term effect of edge to edge mitral repair for mitral vavle moderateto-severe insufficiency in children retrospectively.Methods Clinical dates of 102 patients who underwent edge to edge mitrel valve repair in Nanjing Children's Hospital from March 2003 to March 2015 were collected.Postoperative thoracic echocardiography was adopted to observe the effect of mitral valve forming and evaluate the follow-up results.Results The whole group of 2 patients died in hospital,Followed up for 1 months to 12 years,during the follow-up of 10 patients were lost.The early fol low-up,medium-term follow-up and long-term follow-up were completed 93,55 and 26 cases,respectively.In the early followup,6 patients had recurrent moderate mitral regurgitation(MR),and 5 patients had recurrent moderate-to-severe MR and reoperated during the follow-up period,a total of 2 cases died.In the medium-term follow up,moderate and severe MR were found in 6 and 4 cases,respectively.Three patients accepted reoperation,two patients died.In the long-term follow-up,1 case had recurrent severe MR,2 cases had re-operation and had no death.Early survival rate was 97.8 ％ (91/93),avoid reoperation rate was 94.6％ (88/93).The incidence of moderate or severe mitral regurgitation was 11.8％ (11/93).Midtcrm survival rate was 96.4％ (53/55),avoid reoperation rate was 94.6％ (52/55),moderate or severe mitral regurgitation rate was 18.2％ (10/55).Long-term follow-up have no death,avoid reoperation rate was 92.3 ％ (24/26),mitral valve moderate and above reflux rate was 7.7 ％ (2/26).The actuarial survival and freedom from MV reoperation rate was (92.4 ± 2.4) ％ and (77.7 ± 6.4) ％ at 10 years,respectively.Conclusion Edge to edge mitral repair in the treatment of children with moderate to severe mitral insufficiency had relatively stable curative effect,relatively fewer complications,and high long-term clinical effect.

The effects of a non-selective inhibitor of cyclo-oxygenase (COX) indomethacin, and exogenous prostaglandin E(2) (PGE(2)) on A(delta) units and C units in the saphenous nerve of diabetic hyperalgesic rats were studied. The results showed that the conduction velocity of A(delta) units and C units and their mechanical threshold in diabetic hyperalgesic rats were obviously decreased, and a small number of A(delta) units (4/24) and C units (2/18) produced increased spontaneous activities. Intraperitoneal injection of indomethacin in diabetic hyperalgesic rats significantly relieved mechanical hyperalgesia, and resulted in a decrease in spontaneous afferent activities of the A(delta) units and C units. Subcutaneous injection of exogenous PGE(2) into the diabetic hyperalgesic and control rats produced a significant decrease in mechanical threshold of the A(delta) units and C units, and elicited discharge from 3 A(delta) units (3/24) and 1 C unit (1/18) in diabetic hyperalgesic rats and from 2 A(delta) units (2/13) in control rats. The present data suggest that the synthesis and release of PGs are increased in diabetic neuropathy, PGs can sensitize and /or activate A(delta) units and C units and elicit hyperalgesia and allodynia in diabetic rats.

BACKGROUNDInterleukin 16 (IL-16) can be detected by ELISA in pleural effusion (PE) and its concentration is higher than in serum. This study investigated the cellular sources of IL-16 in PE.

METHODSThe samples of PE were collected from 34 patients who were newly diagnosed having PE in the pleural cavity. We performed cell culture to purify the pleural mesothelial cells (PMC), Wright staining to count the purity and immunocytochemical stain to identify the cultured cells. The intracellular IL-16 expression was detected by flow cytometry (FCM). The different cells in PE were first separated by magnetic cell sorting (MCAS) then the separated cells were cultured in RPMI1640 with 10% fetal calf serum (FCS). We extracted the supernatant and detected IL-16 concentration by ELISA. The IL-16 protein was detected by immunohistochemistry and double immunofluorescence staining.

RESULTSThe percentages of cells which secreted IL-16 were: CD3(+)CD8(-) cells ((74.27 ± 15.56)%, n = 34); CD3(+)CD8(+) cells ((69.86 ± 18.55)%, n = 34); CD19(+) cells ((45.30 ± 18.77)%, n = 15); CD14(+) cells ((16.91 ± 16.69)%, n = 15); and PMC ((2.05 ± 1.85)%, n = 7). The concentrations of IL-16 in the supernatant from cultured cells were: CD4(+) cells ((102.50 ± 42.51) ng/L, n = 5); CD8(+) cells ((92.58 ± 18.34) ng/L, n = 5); CD19(+) cells ((79.85 ± 5.62) ng/L, n = 5); CD14(+) cells ((58.51 ± 25.38) ng/L, n = 5); and PMC ((18.14 ± 8.37) ng/L, n = 5). In lymphocytes, monocytes/macrophages and PMC, we could observe the cells that expressed IL-16 protein. In paraffin-embedded sections, we also could observe by immunohistochemistry the CD4(+)IL-16(+) cells, CD8(+)IL-16(+) cells, CD19(+)IL-16(+) cells, and CD14(+)IL-16(+) cells.

CONCLUSIONSIL-16 in PE is mainly secreted by T lymphocytes, including CD3(+)CD8(-) cells and CD3(+)CD8(+) cells. CD19(+) cells and CD14(+) cells can also secrete IL-16, but the percentage of PMC that can secrete IL-16 is very low.

OBJECTIVETo investigate the clinical characteristics, surgical treatment and prognosis analysis of localized retroperitoneal Castleman disease (CD), and to improve the level of diagnosis and treatment of retroperitoneal Castleman disease with paraneoplastic pemphigus (PNP).

METHODSThe clinical data of retroperitoneal CD with PNP from January 1993 to May 2009 were compared with CD without PNP retrospectively, including clinical features, tumor site, lab examination, surgical treatment, pathologic subtype and results of surgery.

RESULTS(1) Retroperitoneal Castleman disease more likely originated in para-kidney and iliac fossa with middle age of 36 years old, especially in left retroperitoneum. Of the 20 cases, 18 tumors (90%) were hyaline vascular variants and 2 were mixed variants. There was no statistical difference in gender, age, tumor site and pathological subtype between two groups. (2) Retroperitoneal CD with PNP more likely complicated with bronchiolitis obliterans (BO) and high level of serum CEA/CA242. (3) Retroperitoneal Castleman tumors had clear margin, intact envelop and were easily resectable, however the biological behavior of CD with PNP might tend malignant changing, invade adjacent blood vessel or seed locally, and eventually relapse after operation. (4) The 5-year survival rate of retroperitoneal CD with PNP was 42.8%, significantly lower than those without PNP. The average survival time was 30 months. Bronchiolitis obliterans and radical resection were the key effect in prognosis of retroperitoneal CD.

CONCLUSIONSRetroperitoneal CD with PNP has distinctive clinical features. Early diagnosis, prompt removal of tumor and termination secretion of causative antibody are critical to the management of this disease.
