According to traditional Chinese medical theory"Qi in motion can normalize blood circulation". To study the therapeutic effect of herbs regulating Qi on inhibition of tumor metastasis,their influence on blood stasis was investigated. Results showed that the herbs could slow down platelet aggregation and normalize the balance between TXA2 and PGI2. Hence,the herbs could inhibit tumor growth and metastasis.

Objective To asses the value of fluorescence in situ hybridization (FISH) in diagnosis of transitional cell carcinoma of bladder in the urine using directly labeled DNA probes to the pericentromeric regions of chromosomes 3 , 7 and 17 and to the region of P16 tumor suppressor gene. Methods Chromosomal and gene abnormalities were detected using directly labeled DNA probes to the pericentromeric regions of chromosomes 3 , 7, and 17 and to the region of P16 tumor suppressor gene. The sensitivity of FISH and Cytology in diagnosing transitional cell carcinoma of bladder was also compared. Results The sensitivity of FISH and Cytology in diagnosing the disease was 85.5% and 34.2%, respectively. The sensitivity of FISH was prior to that of Cytology( P ＜0.05 ) and increased with increasing tumor pathologic grade but not clinical staging. Conclusions High sensitivity of FISH in diagnosing transitional cell carcinoma of bladder was obtained and it might be a potent method to diagnose bladder cancer in Chinese people in the future.

OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.

OBJECTIVETo compare the difference in the efficacy on thoracic facet joint disorder between the combined therapy of electroacupuncture and manual reduction and the simple manual reduction.

METHODSOne hundred and sixty patients were randomized into an electroacupuncture and manual manipulation group (group A) and a simple manual manipulation group (group B), 80 cases in each one. In the group A, Ashi points and three pairs of Jiaji (EX-B 2) bilateral to the painful sites were selected. The perpendicular puncture was used at Ashi points, the oblique puncture was used at Jiaji (EX-B 2) and connected with electric stimulation for 20 min, additionally, the corresponding manual reduction was adopted at the sites of facet joint disorder. In the group B, the simple manual reduction was applied to the affected sites. Acupuncture was given once every day, the manual reduction was applied once every 10 days. The treatment of 10 days made one session. The efficacy was analyzed statistically at the end of two sessions of treatment. Before and after treatment, McGill pain scale was adopted for the value statistical analysis. PRI score, VAS score and PPI score of patients were calculated before and after treatment and compared in the two groups. The efficacy was compared between the two groups.

RESULTSThe curative rate was 56.3% (45/80) in the group A, which was better than 18.8% (15/80) in the group B (P< 0.01). The total effective rate was 95.0% (76/80) in the group A, which was better than 76.3% (61/80) in the group B (P<0.01). The scores of PRI, VAS and PPI after treatment were all improved significantly in the two groups (all P<0.05), in which, the results in the group A were better than those in the group B (PRI: 4.00 +/- 0.97 vs 5.44 +/- 1.16, VAS: 3.29 +/- 0.72 vs 3.87 +/- 0.81, PPI: 1.07 +/- 0.74 vs 1.64 +/- 0.90, all P<0.05).

CONCLUSIONThe combined therapy of electroacupuncture and manual manipulation achieves the superior efficacy on thoracic facet joint disorder as compared with the simple manual manipulation. The combined therapy relieves the symptoms of thoracic facet joint disorder and reduces the severity of disorder.

Objective To evaluate the medium-term outcomes of minimally invasive percutaneous nephrolithotomy in patients with renal function impairment.Methods Data of 811 patients who underwent minimally invasive percutaneous nephrolithotomy between Jan.2009 and Dec.2011 were retrospectively collected.Seventy-eight patients had a preoperative estimated GFR of 30-59 ml/(min · 1.73m2).The minimum follow-up was 1 year.Patients were divided into group 1 (improved or stable disease) and group 2 (worsened disease).Patient age was (42.8 ± 16.3) and (45.3 ± 14.2) separately,with male patients 41 and 7,female patients 25 and 5 respectively.Body mass index were (24.3 ± 4.1) kg/m2 and (25.4 ±5.2) kg/m2,history of open surgery or ESWL were 19 and 4.Mild hydronephrosis were 22 and 4.Staghorn stone were 22 and 5.Multiple access were 13 and 2.Operative time was (78.2 ± 30.4) min and (80.3 ±32.3) min.Stone-free rate 1 month postoperatively were recorded.Multiple regression analysis was used.Results The stone free rate at 1 month postoperatively was 85％ by CT scan.Preoperative eGFR was (38.4±12.8) ml/(min · 1.73m2),and 1 ycar postoperative eGFR was (45.1 ±15.8) ml/(min · 1.73m2)in 78 patients.Renal function had improved in 31％ of patients,but it remained the same or deteriorated in 54％ and 15％,respectively at 1 year follow-up.On multivariate regression analysis,diabetes was associated with the deterioration of renal function.Conclusions At medium-term follow-up,renal function was maintained or improved in 85％ of patients with chronic kidney disease who underwent minimally invasive percutaneous nephrolithotomy.Minimally invasive percutaneous nephrolithotomy could be an effective and safe option for the patients with chronic renal function impairment.Diabetes mellitus was independent predictive factor of renal function impairment.Therefore,patients with diabetes should be followed up carefully.Medical management is needed if necessassry.

Objective To investigate effects of α-crystallin on proliferation of lipopolysaccharide (LPS)-activated retinal microglia and bioactivity of iNOS.Methods The retinal microglial cells cultured in vitro were analyzed and their purity was identified by cell immunofluorescence and flow cytometry.After microglia cells being intervened using LPS and α-crystallin at various concentrations,influence of α-crystallin on activity of LPS-activated retinal microglia was detected by MTT method and level of NO was measured by RT-PCR to observe changes of iNOS expression in microglia.Results Purity of primary cultured microglial cells was 94.15％ by GSA-IB4 immunohistochemical identification and 93.34％ by CD11b flow cytometry.α-crystallin of 10-4g/L awakened activity of microglia induced by 10-6g/L LPS (P ＜ 0.01).Expressions of iNOS protein and mRNA showed significant decrease in combined treatment group (P ＜ 0.05).Conclusion In clinical condition,α-crystallin decreases the harm of microglial cells on retinal ganglial cells (RGCs) after optical nerve injury by inhibiting the microglia cells to produce NO and iNOS.

Background and purpose:Cancer is a common disease. Multidisciplinary approach is the best model for cancer treatment. Cancer staging is the basis for diagnosis, treatments and prediction of prognosis.The survey is to give an overview of the current application of cancer multidisciplinary approach and UICC or other international cancer staging in mainland China. We made inquiries to our Chinese oncologists’ experience of using these staging and share their comments and recommendations. For those cancers common in China, Chinese oncologists and academic societies should provide more information of staging, therapies, outcome, prognostic predictors of prognosis, etc. to make international stage systems, like UICC or AJCC, a more appropriate, accurate and acceptable guide to individual patients’ staging and treatment, to predict outcome and to facilitate clinical trials better. Methods: This survey was done from 2012 to 2013 by questionnaires. The questions were answered for 10 major cancers in China (liver cancer, esophageal cancer, nasopharyngeal carcinoma, lung carcinoma, breast cancer, gastric cancer, colorectal cancer, gynecologic cancer, prostate cancer and lymphoma). Thirty-three questionnaires have been answered by national wide hospitals including provincial cancer hospitals, district cancer hospitals and departments of oncology in general hospitals. We also site visited 7 grade B hospitals. Results:Multidisciplinary approach is not widely used in the hospitals. UICC or AJCC stages have been widely used for 10 cancers, but for cancers that were uncommon in the West;while common in China (nasopharyngeal carcinoma, liver cancer) the staging proposed by Chinese society have also been used to replace UICC/AJCC. Conclusion:We suggest a wild implementation of multidisciplinary approach. For those cancers common in China Chinese oncologists and academic societies should provide more information of staging, therapies, outcome, prognostic predictors of prognosis etc. to make international stage systems, like UICC or AJCC, a more appropriate, accurate and acceptable guide to individual patients’ staging and treatments, to predict outcome and to facilitate clinical trials better.

Objective To assess the safety and efficacy of a novel technology referred to as percutaneous ureteroscopic laser deroofing in the management of renal cysts.Methods From November 2014 to August 2016,59 patients having surgical indications with renal cysts were enrolled and evaluated by ultrasound and CT scan.Of all the 59 patients,36 were males and 23 were females.Their mean age was 46 years (ranging 35-64 years).41 patients complained about the reported flank and abdominal pain.18 patients were found by imaging examination.Their mean diameter of cyst was 6.3cm(ranging 4.9-9.1cm).In regards to the 59 patients,include 6 patients suffered with parapelvic cysts and 4 patients suffered with renal cyst complicated with ipsilateral renal calculi.Their mean stone surface area was 5.7 cm2 (ranging 3.4-9.8 cm2).All of the patients received combined spinal and epidural analgesia or paravertebral nerve block anesthesia.Patients were placed in the prone position for percutaneous puncture and tract dilation.Under ultrasound guidance,an eighteen gauge needle was placed inside the cyst cavity percutaneously,a metal guidewire was introduced followed by sequential dilation up to F26-28.9.8F rigid ureteroscope was inserted through the Amplazt access sheath and advanced into the cyst cavity.Then sheath and ureteroscope both returned to the exterior cyst together.Cyst wall was dissociated from perirenal adipose tissue by used ureteroscope.A majority of the collapsed cyst wall was grasped and gently pulled towards the Amplazt sheath interior using grasping forceps and incised using either Thulium (Power 40 ～50W) or Holmium laser(Power 60 ～70W) and was taken for pathological examination.Nephrostomy tube was left in place for 2-3 days and removed before discharge.For parapelvic cysts patients,ureter stent was inserted into the renal pelvis i n the dorsal lithotomy position firstly.Patients were then placed in the prone position for percutaneous puncture and tract dilation.Laser was used to incise cyst wall towards identified pelvis to create a permanent communication between the cyst and adjacent renal collecting system.F6 double-J stent was inserted into the cyst cavity at the end to prevent auto-closure for at most two months.F22 nephrostomy tube was left in renal pelvis for two weeks.For renal cyst complicated with ipsilateral renal calculi patients,a puncture was created targeting the stone through the cyst,after fragmenting and extracting the stone,the same laser was used to deroof the cyst.More than 50％ reduction in cyst volume was considered a success.The perioperative complications,hospitalization days and the effective rate of surgery were evaluated.Results All operations were conducted without intraoperative complications such as bleeding,urinary leakage or injury of the renal parenchyma and the adjacent organs.The hospital stay after the surgery was 2-4 days (mean 2.5 days).After 3-12 months follow-up (mean 8.1 months),patients underwent imaging examinations.42 out of 59 cases were completely resolved,15 were reduced to less than 50％,the total effective rate for the operation is 96.6％ (57/59).4 patients with ipsilateral renal calculi were completely clear.However,two cases failed probably due to incomplete resection and follow treated with laparoscopic renal cyst deroofing.Conclusions Percutaneous ureteroscopy renal cyst laser deroofing is a safe,effective,less invasive,which can be performed in any endourological center without the need of special instruments and training.

Objective To study the effects of a synthetic miR3619-5p mimics on bladder carcinoma cell lines of EJ and T24 in vitro.Methods EJ and T24 cells were cultured in vitro and treated with three different processing:negative control group(tinfection with dsControl),positive control group(infection with dsP21-322) and the experimental group(infection with miR-3619-5p)during October 2015 to March 2016.Real-time fluorescent quantitative PCR (qPCR) was performed to detect the expression of p21 mRNA,cell cycle protein D1 (CyclinD1) and cell cycle-dependent kinase (CDK4 and CDK6) mRNA.Western Blot method was conducted to evaluate the expression of p21,CyclinD1 and CDK4 and CDK6 proteins;the change of cell cycle was displayed by flow cytometric analysis.Colony formation assay was used to test the ability of single cancer cell clone proliferation.Cell proliferation assay(MTS) was implemented to observed the inhibitive effect of cell proliferative potential.Results qPCR results showed that miR-3619-5p upregulated p21 mRNA expression (P ＜ 0.05),while the expression of CyclinD1,CDK4 and CDK6 were a little lower(P ＜ 0.05) in EJ and T24cells,respectively.Western Blot analysis testified that the expressions of p21,CyclinD1,CDK4 and CDK6 were difference among groups.Flow cytometry displayed that,the G0/ G1 phase increased significantly after transfected with miR-3619-5p and dsP21-322,compared with dsControl group(P ＜ 0.05),indicating that the cell cycle block in G0/G1 phase.Cell colony formation assay certified that the colony formation rates were less in the groups of miR-3619-5p and dsP21-322 than in that of dsControl group(P ＜ 0.05).Cell proliferation assay demonstrated that,cell proliferation ability decreased obviously when transfected with miR-3619-5p and dsP21-322 (P ＜0.05),compared with dsControl group.Conclusions miR-3619-5p could up-regulate the expression of p21 by RNA activation pathway and remarkably induced cell cycle arrest in G0/G1 phase,inhibiting the proliferation of bladder cancer cells.
