This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

OBJECTIVETo investigate the effect of multi-plane Hyaluronic acid (HA) injection for rhinoplasty.

METHODSThe HA was injected below or above the periosteum at the nasal bone, above the perichondrium at the cartilage portion of nose, and between the great alar cartilage at the nasal tip. The HA volume was 1-1.5 ml, according to the nose form and aesthetic assessment. Over-injection was not permitted. Touch-up injection could be performed one week after the first injection if need.

RESULTSFrom Jan. 2010 to Jan. 2012, 60 cases underwent rhinoplasty with HA injection. The patients were followed up for 10-13 months with satisfactory result. The effect lasted about 9 months with the longest period as 12 months and the shortest period as 6 months.

CONCLUSIONSGood results can be achieved with multi-plane HA injection for rhinoplasty.

OBJECTIVETo evaluate an enzymatic method for determining serum beta-hydroxybutyrate (beta-HB) with the National Committee for Clinical Laboratory Standards (NCCLS) projects, and to discuss its clinical values in diabetic ketoacidosis (DKA).

METHODSThe precision, accuracy, specificity, linearity and interference of the enzymatic method were analyzed. This method was used to determine serum beta-HB in 60 cases of normals, 50 cases of diabetes, and 34 cases of DKA by autochemistry analyzer.

RESULTSEnzymatic beta-HB assay was precise (within-run CV, day-to-day CV, and total CV < 5%). The linearity studies showed the method was linear up to 4 mmol/L. Recovery rate was 98.5%-104.1%. Hemolysis (Hemoglobin up to 18.2 g/L), icteric samples with total bilirubin up to 224 mumol/L, and lipemia up to triglyceride concentration of 2.28 mmol/L did not interfere with the beta-HB results in this method. Serum beta-HB levels were significantly elevated in DKA patients compared with DM patients and controls (P < 0.01). Positive rate of serum beta-HB in DKA patients was significantly higher than that of urinary ketone (P < 0.05).

CONCLUSIONSEnzymatic method is convenient and reliable, allows full automation, and is rapid enough to be used for both routine and urgent determinations of serum beta-HB. It can be used in diagnosing and monitoring treatment of DKA.

OBJECTIVESTo suggest the clinical classification of the far-lateral lumbar disc herniation and offer the considerations for clinical choice of different surgical procedures.

METHODSAccording to the locations of the herniated disc and relevant clinical symptoms, the far-lateral lumbar disc herniation was divided into three types: Type I: posterolateral and foraminal herniation(double herniations); Type II: foraminal disc herniation and Type III: extraforaminal herniation. From January 2002 to January 2007, 38 patients with far lateral lumbar disc herniation underwent surgery in the institute. The surgical options were decided by means of the classification. The surgical procedures included (1) discectomy by inter-TP (transverse process) approach, (2) discectomy with partial facetectomy and (3) discectomy with facetectomy and PLIF (posterior lumbar interbody fusion). Among the 38 patients, there were 25 males and 13 females. The mean age was 58.4 years old. The herniated discs located at L(3-4) in 17, L(4-5) in 13, and 8 cases at L(5)S(1). Twenty-three patients were simple disc herniation, 15 cases with concomitant lumbar spinal stenosis. The symptoms and signs of exiting root compression at herniated disc level were presented in all patients and passing root compression presented in 7 Type I cases as well; while intermittent claudication being presented in 15 and low back pain in 21 patients. The VAS (visual analog pain scale) of radicular leg pain was taken before and after the operation. The postoperative outcomes were evaluated through the MacNab's method in all the patients.

RESULTSBy using the new classification system, the 38 patient were divided into Type I 10 cases, Type II 19 cases and Type III 9 cases. The adopted surgeries included discectomy by intertransverse approach in 5, discectomy with partial facetectomy in 7, and discectomy with facetectomy and PLIF in the rest 26 cases. The mean follow-up period was ranging from 6 months to 4 years and 10 months, average 2 years and 11 months. The mean VAS scores of radicular pain was 7.4 preoperatively, 2.7 at 2 weeks after the operation and 3.1 at final follow-up. The final clinical outcomes by MacNab's method were as follow: excellent results in 20 cases, good in 12, fair in 5 and poor in 1 case. The overall improvement ratio was 84.2%. The postoperative complications included superficial wound infection in 1 case, insufficient decompression in 1 case and leakage of cerebrospinal fluid in 1 case respectively. No breakage and loosening of internal fixation were detected.

CONCLUSIONSA new clinical classification of far lateral lumbar disc herniation was suggested, which is significant to understanding the relevant pathology and choosing the surgical procedures.

OBJECTIVESTo find possible factors correlated with combined loss of heterozygosity (LOH) of 1p and 19q.

METHODSThe status of 1p and 19q of 138 glioma specimen from January 2009 to December 2009 was evaluated by Fluorescence in situ hybridization (FISH) method, and the frequencies of combining LOH of 1p/19q were compared between different pathologies, brain sub-regions, genders and ages.

RESULTSThe frequencies of combined LOH of 1p and 19q of oligodendroglial (81.3%) and oligo astrocytic tumors (55.8%) were significantly higher than that of astrocytic tumor (22.2%) (P < 0.01), and the frequency of oligodendroglial tumor was significantly higher than that of oligo astrocytic tumor (P < 0.05). The frequency of combining LOH of 1p and 19q in frontal lobe (61.8%) was higher than that in temporal (31.8%) and insular lobes (34.6%) (P < 0.05).

CONCLUSIONCombining LOH of 1p and 19q has significant correlation with the pathologies and brain sub-regions.

BACKGROUND: MAVERIC (Mitral Valve Repair Clinical Trial) validates the safety and efficacy of the ARTO system. We here report the first two successful cases of utilizing the ARTO system in patients with symptomatic heart failure (HF) with functional mitral regurgitation (FMR) in Asia. METHODS: Two patients, aged 70 and 63, had severe HF with FMR. Transesophageal echocardiography confirmed that the left ventricular ejection fractions were less than 50% with severe mitral regurgitation (MR) in both patients. Optimizing drug treatment could not mitigate their symptoms. Therefore, we used the ARTO system to repair the mitral valve for these patients on March 5 and 6, 2019, respectively. RESULTS: Mitral valve repairs using the ARTO system were successfully performed under general anaesthesia for these two patients. MR was decreased immediately after the procedures in both patients. The 30-day and 3-month transthoracic echocardiography (TTE) revealed a moderate to severe MR in both patients, and the New York Heart Association (NYHA) scales were also partially improved. CONCLUSION The first two cases in Asia indicate that the ARTO system is feasible for patients with heart failure with FMR, and the patient selection appears to be crucial.

BACKGROUNDPosterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM). Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM.

METHODSForty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L) and hemilaminectomy (Group H). Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA), and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared.

RESULTSNeurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41%) than in Group H (62.72 ± 3.86%) (P < 0.01).

CONCLUSIONSBoth surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

OBJECTIVETo investigate the effects of surgery treatment on serious penile lesions and malformation.

METHODSSixty-two patients, aged from 19 to 63 years old (mean 35 ys), were included in the study. Among them, 4 patients suffered from penis partial defection were respectively treated with restoring defective penis, penis lengthening and urethroplasty; three patients with penis completely missing were treated with penis reconstruction surgery; 22 cases with serious penile curvature were treated with the 16-dot plication technique (Lue's procedure); 15 cases with penile fracture were treated with conservative treatment for 1 case and with patch penis, corpus spongiosum, and deep penile dorsal vein ligation for 14 cases; 5 cases with post-operative complications of 3-pieces of penile prosthesis, including the prosthesis perforating to the urethra, water pump failure, broken connection tube, erection angle < 60 degrees and failure to expansion the corpus cavernosum, were treated by taking out prostheses, urethral repair cracks, replacement of the prostheses, excision of fibrosis scar and re-implantation prostheses respectively. Four cases with penis complete amputation were treated with the penis replantation; three cases of avulsion injury were treated with the replantation and free flap skin; 6 with Paget's disease of penises were treated with the lesion free skin buried in the scrotum and penis.

RESULTSAll these patients were followed up for 3 months to 4 years, with the average of 9 months. Among the 4 cases of penis partial defection, 2 patients were satisfied with the penile appearance and sexual function; 1 got some satisfactory and 1 was unsatisfied. Three cases with the loss of the penis completely were satisfied with both the postoperative appearance and urination, and 1 was not satisfied. Twenty-two cases of penile curvature deformities were corrected, and one case was recurrence. Fourteen of the 15 patients with penile fracture were followed, and all got the restoration of sexual function. Among them, 5 cases with post-operative complications, including mild bending, algopareunia, subcutaneous induration, poor hardness and poor sexual pleasure, were not further treated, and another case lost; Five cases with post-operative complications of three-pieces penile prosthesis were treated successfully, and 4 of their spouses were satisfied with their sexual function after operation, only 1 of their spouse not satisfied. Among four cases with complete amputation of penis, two cases of penis were replanted successfully while two necrosis. Three cases with avulsion were treated with skin grafting successfully. All 6 cases with penile Paget's disease were followed for 2 -4 years, and free skin grafts were all survival. One patient died of brain metastases 18 months after operation and five cases were disease-free survival.

CONCLUSIONThe patients should be treated based on the procedure of andrological and urological surgery, together with microsurgical, flap or skin graft technique. The urologist should design personalized surgical procedure. Most of the patient's penis shape and erectile dysfunction can be reconstructed by our procedures, but some patients can not achieve the desired appearance or function of penis. New approaches of the treatment ought to be developed to restore both of the shape and function for those severe injury of the penis.

Objective:To evaluate the safety and efficiency of robotic visualization system(RVS)-assisted microsurgical re-construction of the reproductive tract in male rats and the satisfaction of the surgeons.Methods:We randomly divided 8 adult male SD rats into an experimental and a control group,the former treated by RVS-assisted microsurgical vasoepididymostomy(VE)or vaso-vasostomy(VV),and the latter by VE or VV under the standard operating microscope(SOM).We compared the operation time,me-chanical patency and anastomosis leakage immediately after surgery,and the surgeons'satisfaction between the two groups.Results:No statistically significant difference was observed the operation time between the experimental and the control groups,and no anasto-mosis leakage occurred after VV in either group.The rate of mechanical patency immediately after surgery was 100％in both groups,and that of anastomosis leakage after VE was 16.7％in the experimental group and 14.3％in the control.Compared with the control group,the experimental group achieved dramatically higher scores on visual comfort(3.00±0.76 vs 4.00±0.53,P＜0.05),neck/back comfort(2.75±1.16 vs 4.38±1.06,P＜0.01)and man-machine interaction(3.88±1.55 va 4.88±0.35,P＜0.05).There were no statistically significant differences in the scores on image definition and operating room suitability between the two groups.Conclusion:RVS can be used in microsurgical reconstruction of the reproductive tract in male rats and,with its advantages over SOM in ergonomic design and image definition,has a potential application value in male reproductive system micosurgery.

Leiomyosarcoma of urinary bladder (LMS-UB) is a highly malignant mesenchymal tumor, accounting for less than 0.5% of all bladder malignancies, with a predominant clinical presentation of hematuria. Here we report a case of low-grade LMS-UB. A 44-year-old male patient was admitted to the hospital with urodynia for 2 weeks. The patient's pelvis CT showed a mass on the right part of the bladder. For this reason, he was initially diagnosed with bladder cancer. We performed a robot-assisted laparoscopic enucleation of the bladder tumor and low-grade LMS-UB was diagnosed with the histopathological examination. He underwent 5 cycles of adjuvant chemotherapy after surgery. At 19months postoperative follow-up, the patient had no symptoms, recurrence, or distant metastasis. There is no report on the treatment of LMS-UB with minimally invasive enucleation worldwide. This case provides a new comprehensive treatment method of enucleation combined with adjuvant chemotherapy for early low-grade LMS-UB to reduce complications and improve patients' quality of life after surgery.
