Objective To investigate the clinical value of the massive transfusion protocols (MTP) in abdominal surgical patients with traumatic shock.Methods An analysis was made on the clinical data of patients before and after the use of MTP,including the general condition,amount of blood transfusion,transfusion components and ratio,blood and coagulation function test,and blood transfusion related complications and mortality.Results Before implement of MTP,the average RBC transfusion in the first 24 hours was 19.5U,FFBwas 12.6U,and the ratio ofRBC ∶ FFB was 1.55 ∶ 1.After implement of MTP,the average RBC transfusion in the first 24 hours was 17.3 U,and the ratio of RBC:FFB was 1 ∶ 1.There were no significant statistical differences between the two groups about PT,APTT,Hb and PLT on admission.After 24 hours of admission,there was no significant difference in Hb between the two groups,there were significant differences of PT,APTT and PLT.Blood transfusion related complications were 11 (14.9％) in control group and 7 (11.9％) in MTP,group,and the mortality was 9.46％ and 6.78％ respectively.Conclusions MTP improves blood coagulation function,reduces blood transfusion and enhances survival rate of abdominal surgical patients with traumatic shock.

Objective To quantitatively analyze radiation-induced trismus in patients with nasopha-ryngeal carcinoma (NPC) treated by intensity modulated radiation therapy (IMRT), and evaluate tem-poromandibular joint (TMJ) damage. Methods Between February 2001 and October 2004, 211 NPC pa-tients were treated by IMRT, with a total dose of 68 Gy, 2.27 Gy per fraction within 31 -86 days (median, 43 days). The distances between two dens incisivus medialis (DDIM) were measured before and 6 months after IMRT and then annually thereafter. Results The overall survival at 1-, 3-, and 5-year were 97.1%, 90.7% and 79. 1%, respectively. The mean irradiation doses to TMJ were 6.18 -51.36 Gy. Grade 1 TMJ damage was observed in 5.2% patients, and grade 2 occurred in one patients who had received the second course radiotherapy because of local relapse . No grade 3 or 4 TMJ toxicity was observed . Conclusions IMRT can spare the TMJ from high dose irradiation and markedly reduce severe TMJ damage.

ObjectiveTo investigate the correlation between polymorphism of interleukin(IL)-1β genes and risk and pathological characteristics of gastric cancer in human.MethodsFrom January to December 2010,200 cases of gastric cancer(patient group) and 200 cases of chronic superficial gastritis (control group) were collected.DNA was extracted and IL-1β gene -511,-31,-1473,+3954 site were detected by gene chip technology.The correlation between IL-1β gene -511,-31,-1473,+3954 site and risk and pathological characteristic of gastric cancer was observed.ResultsThe genotype frequency of IL-1β gene -511,-31,-1473,+3954 site was 48.75％(195/400),55.25％(221/400),53.25％(213/400),50.75％ (203/400) in patient group,47.25％ (189/400),53.00％ (212/400),52.50％ (210/400),52.50％ (210/400) in control group,and there was significant difference between two groups (P ＜0.05).While IL-1β gene -511,-31 site T allelic with the lower degree of differentiation of gastric cancer,IL-1 β gene -511,-1473 site T allelic with the early age of gastric cancer.ConclusionsIL-1β gene -511,-31,-1473,+3954 site genotype increase the risk of gastric cancer.IL-1β gene -511,-31 site T allelic are related with the degree of differentiation of gastric cancer.IL-1β gene -511,-1473 site T allelic are related with age of gastric cancer patient.

Distant metastasis is the main cause of cancer death. Tetraspanins (transmembrane 4 superfamily, TM4SF) is capable of forming transmembrane complexes with integrin family participating in cell adhesion, migration and tumor metastasis. This review elucidates the structure of tetraspanins and its function in regulating metastasis as form of multimolecular transmembrane complexes with integrin.

Objective To explore the diagnostic significance of differential cell count in induced sputum to chronic cough and assessment of airway inflammation.Methods The sputum of 335 chronic cough patients were induced.Differential cell counts were measured in these samples.The side effects were observed during the induced procedure.The final diagnosis was made based on clinical manifestation and examination findings including pulmonary function tests,provocation test,induced sputum cell differentials, etc.Results The cause of chronic cough was defined in 322 patients.The six most important causes of cough were typical asthma(TA,n=84),eosinophilic bronchitis (EB,n=62),atopic cough (AC,n= 42),cough variant asthma (CVA,n=40),gastroesophageal reflux cough(GERC,n=37),rhinitis and/ or paranasal sinusitis (PNDs,n=32),and others and indefinite cause (n=25,13).Percentage of eosinophils were significantly increased in the induced sputum of AC,EB,CVA,and GERC patients (0.005,0.052,0.059,0.234) compared with those in other causes and the healthy controls (0) (P

Objective To explore the feasibility and safety of the posterior approach of robotassisted laparoscopic radical prostatectomy and to the approach.Methods From November 2001 to April 2017,32 patients underwent posterior approach of robot-assisted laparoscopic radical prostatectomy.Patients aged 53 to 81 years,with mean of 66.9 years old.Their prostate volumes were 12.0-73.7 ml with an average of 32.9 ml.All patients were diagnosed by prostate biopsy before surgery.The operation time,blood loss and length of hospital stay were recorded.Results All the operations were completed by robotic assisted laparoscopy with no transition to open surgery.The surgery time was 129-210 minutes with an average of 163.6 minutes.The estimated blood loss was 20-200 ml with an average of 59.3 ml.The hospital stay was 8-21 days with an average of 12.8 days.The postoperative hospital stay was 3-13 days with an average of 6.9 days.The time of postoperative catheter removal was 4-14 days with an average of 7.5 days.Postoperative follow-up was 1-6 months.Twenty-four (75％) patients had early recovery of continence,and all (100％) patients regained continence 3-month postoperatively.Conclusion The posterior approach of robotic assisted laparoscopic radical prostatectomy was a safe and effective surgical technique,which was beneficial in early continence recovery.

The incidence of renal cell carcinoma (RCC) is increasing. Radical cure by surgery can only be achieved in patients with early stage tumors. How to precisely use antineoplastic agents after surgery is an important problem to be solved. Most metastatic RCCs are pathologically identified as clear cell RCC (ccRCC), thus to develop agents targeting ccRCC is critical. Most clinically available targeted therapies are based on targeting some spots in specific pathways; or based on targeting new anti-tumor mechanisms, such as programmed death-1(PD-1), antibody-drug conjugates (ADC) and stem cells. There is still no targeted therapy having definite effect to most RCC patients. Only von Hippel-Lindau (VHL) pathway so far has been confirmed to be related to ccRCC development and progression; the inactivation of VHL gene causes many significant downstream gene changes. The key proteins involved in VHL pathway may be potential therapeutic targets for ccRCC. In this article, we review the current progress of targeted therapy for RCC, focus on the molecular characteristics of ccRCC, its relation to VHL pathway, the potential therapeutic targets and future clinical application for metastatic ccRCC.

INTRODUCTIONA meniscal deficient knee is at risk of early degenerative osteoarthritis. Allograft meniscal transplantation has been used to treat the meniscus deficiency to alleviate pain symptoms and to delay progression to arthritis. This case series aims to assess the postoperative outcomes of patients who have undergone meniscal allograft transplantation in our hospital.

MATERIALS AND METHODSThis is a prospective clinical review of prospectively collected data of our Meniscal Transplantation Programme from 2004 to 2007. Twelve meniscal allografts were implanted in 12 males with symptomatic knees, using arthroscopically assisted techniques. Preoperative and postoperative assessments were conducted using the Visual Analogue Scale (VAS), Tegner Activity Level Scale, Lysholm Knee Scoring Scale, and 2000 International Knee Documentation Committee (IKDC) scoring systems.

RESULTSThe mean age was 26.7 years with a mean follow-up of 17 months (range, 5 to 37). The VAS score for pain improved from 5.5 (3- 10) to 1.4 (0-2) [P <0.05], Tegner from 3 (2-5) to 5.9 (3-9) [P <0.05], Lysholm from 62.5 (27-88) to 88.6 (70-100) [P <0.05], IKDC Subjective Score from 50 (24-79) to 79.5 (56-95) [P <0.05]. Overall IKDC Knee Examination Grades revealed 10 nearly normal and 2 abnormal scores.

CONCLUSIONSThis is the first series of allograft meniscal transplantation from Southeast Asia. Patient outcome evaluation via VAS, Tegner Activity Level Scale, Lysholm Knee Scoring Scale and 2000 IKDC Knee Evaluation Form showed improvement in symptoms and knee function after implantation.
