OBJECTIVETo observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.

METHODSWe treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.

RESULTSStapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).

CONCLUSIONCircumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.

Background/Aims: The incidence of gastroesophageal reflux disease (GERD) is increasing annually. Studies have suggested that psychosocial disorders may be linked to the development of GERD. However, studies evaluating the association between psychosocial disorders and GERD have been inconsistent. Thus, we conducted a systematic review and meta-analysis of observational studies that evaluated the association between psychosocial disorders and GERD. Methods: We systematically searched the PubMed, Embase, Cochrane, and Web of Science databases until October 17, 2020. Pooled OR with 95% CI and subgroup analyses were calculated using a random-effects model. Subgroup analyses were performed to identify thesources of heterogeneity. Sensitivity analysis by one-study removal was used to test the robustness of our results. Results: This meta-analysis included 1 485 268 participants from 9 studies. Studies using psychosocial disorders as the outcome showed that patients with GERD had a higher incidence of psychosocial disorders compared to that in patients without GERD (OR, 2.57; 95% CI, 1.87-3.54; I2 = 93.8%; P < 0.001). Studies using GERD as an outcome showed an association between psychosocial disorders and an increased risk of GERD (OR, 2.23; 95% CI, 1.42-3.51; I2 = 97.1%; P < 0.001). The results of the subgroup analysis showed that the non-erosive reflux disease group had a higher increased risk of anxiety than erosive reflux disease group (OR, 9.45; 95% CI, 5.54-16.13; I2 = 12.6%; P = 0.285). Conclusion: Results of our meta-analysis showed that psychosocial disorders are associated with GERD; there is an interaction between the two.

Objective To summarize our experience with endovascular treatment of vertibrobasilar aneurysms. Methods The clinical data of 21 patients with vertibrobasilar aneurysms admitted between October, 2003 and July, 2007 were retrospectively analyzed. All the 21 patients received endovascular embolization, of whom 11 patients had embolization with Guglielmi detachable coils (GDC), 9 had GDC embolization with Neuroform stent placement, and 1 patient was managed with covered stent placement in the parent artery. Results After the operations, 19 patients were clinically cured with good prognosis, 1 patient was severely disabled, and 1 died due to heart failure. Four patients underwent ventriculo-peritoneal shunting for postoperative hydrocephalus. Conclusions Endovascular embolization with GDC and placement of Neuroform stent and covered stent are effective options for management of vertibrobasilar aneurysms, and most of the vertibrobasilar aneurysms can be treated effectively by these approaches.

OBJECTIVETo evaluate the effect of hypoxia-inducible factor-1 alpha (HIF-la) on angiogenesis in human prostate cancer cells.

METHODSHuman prostate cancer cells of the line LNCaP were cultured and transfected by the recombinant plasmid pcDNA3. 1(-)/HIF-1alpha containing the gene HIF-1alpha with the Lipofectamine 2000 system. The positive clone cells were selected by G418 and confirmed by Western blotting and immunofluorescence (LNCaP/HIF-1alpha cells). The expressions of VEGF, iNOS and Ang-2 were detected by Western blotting.

RESULTSThe expression of HIF-1alpha in the LNCaP/HIF-1alpha cells was distinctly higher than that in the LN-CaP cells. Compared with the LNCaP cells, the expressions of VEGF and iNOS were up-regulated, whereas Ang-2 remained unchanged in the LNCaP/HIF-1alpha cells.

CONCLUSIONThe over-expression of HIF-1alpha can induce an increase in angiogenesis proteins and improve the angiogenesis potency of prostate cancer.

OBJECTIVETo observe the therapeutic effect of Zhenggan Recipe (ZGR) in treating liver cirrhosis with abnormal Alpha-fetoprotein (AFP), and to explore its mechanism.

METHODSSixty-four patients of liver cirrhosis with abnormal AFP were randomly divided into the treated group and the control group. All the patients received conventional combined Western medicinal treatment. Besides, additional ZGR was given to the patients in the treated group, one dose every day for orally taken in two times, 6 months as a therapeutic course. Changes in liver function (ALT, GGT, TBIL and ALB), AFP, T-lymphocyte subsets (CD4, CD4/CD8) and iconological examination were observed in the two groups before and after treatment to compared the efficacy.

RESULTSZGR could effectively lower the AFP level (P < 0.01), and improve the levels of CD4 and CD4/CD8 (P < 0.01 or P < 0.05).

CONCLUSIONZGR can effectively lower the level of AFP, its mechanism might be related to the improving of cellular immune function of the patients.

BACKGROUNDThe treatment of high-grade developmental spondylolisthesis (HGDS) is still challenging and controversial. In this study, we investigated the efficacy of the posterior reduction and monosegmental fusion assisted by intraoperative three-dimensional (3D) navigation system in managing the HGDS.

METHODSThirteen consecutive HGDS patients were treated with posterior decompression, reduction and monosegmental fusion of L5/S1, assisted by intraoperative 3D navigation system. The clinical and radiographic outcomes were evaluated, with a minimum follow-up of 2 years. The differences between the pre- and post-operative measures were statistically analyzed using a two-tailed, paired t-test.

RESULTSAt most recent follow-up, 12 patients were pain-free. Only 1 patient had moderate pain. There were no permanent neurological complications or pseudarthrosis. The magnetic resonance imaging showed that there was no obvious disc degeneration in the adjacent segment. All radiographic parameters were improved. Mean slippage improved from 63.2% before surgery to 12.2% after surgery and 11.0% at latest follow-up. Lumbar lordosis changed from preoperative 34.9 ± 13.3° to postoperative 50.4 ± 9.9°, and 49.3 ± 7.8° at last follow-up. L5 incidence improved from 71.0 ± 11.3° to 54.0 ± 11.9° and did not change significantly at the last follow-up 53.1 ± 15.4°. While pelvic incidence remained unchanged, sacral slip significantly decreased from preoperative 32.7 ± 12.5° to postoperative 42.6 ± 9.8°and remained constant to the last follow-up 44.4 ± 6.9°. Pelvic tilt significantly decreased from 38.4 ± 12.5° to 30.9 ± 8.1° and remained unchanged at the last follow-up 28.1 ± 11.2°.

CONCLUSIONSPosterior reduction and monosegmental fusion of L5/S1 assisted by intraoperative 3D navigation are an effective technique for managing high-grade dysplastic spondylolisthesis. A complete reduction of local deformity and excellent correction of overall sagittal balance can be achieved.

OBJECTIVETo investigate the short-term therapeutic effectiveness of body gamma-knife in patients with advanced pancreatic carcinoma.

METHODSForty-eight patients with advanced pancreatic carcinoma were treated by body gamma-knife therapy. The dosage distribution and other radiotherapeutic plans were established on the basis of the carcinoma position, clinical target volume, and patient health condition. The isodose curve was 50%-60% and covered about 95% of the target volume. The single dose was 350-450cGy. The radiation was performed once every one or two days for 10-12 times.

RESULTSThere were 33 patients with back pain. 63.6% of the patients got completely controlled, 30.3% pain remitted, and 6.1% ineffective after 2 to 18 months of therapy. The analgesic effective rate was 93.9%. Among 28 patients with obstructive jaundice, 21 patients (75.0%) recovered. Among 42 patients who received CT, tumor disappeared in 5 patients (11.9%), tumor size decreased in 30 patients (71.4%), remained unchanged in 5 patients (11.9%), and enlarged in 2 patients (4.8%). The 6-month, 12-month, and 18-month overall survival rates were 77.1%, 37.5%, and 10.4%, respectively. The whole process was tolerable for all patients and no severe side-effect was observed.

CONCLUSIONSBody gamma-knife can achieve a high local control rate and survival rate. Its short-term therapeutic effectiveness is satisfactory. Body gamma-knife is a safe and reliable treatment option for patients with locally advanced pancreatic carcinoma.
