BACKGROUND:At present,measurement osteotomy technique and gap balance technique are the two main surgical methods in total knee arthroplasty.Both methods have their advantages and disadvantages.By adjusting the osteotomy angle,the gap balance technique can reduce the release of soft tissue and obtain a more balanced flexion and extension space.The clinical efficacy of gap balance technique is superior,but this surgical method lacks tools and is easily influenced by the surgeon's surgical experience and subjective judgment,with more errors.Measurement osteotomy technique has a short learning curve,but it relies on anatomic markers and is prone to many complications due to inaccurate positioning.In recent years,many instrument companies have successively developed and launched tools that can improve the quality of surgery.However,there are still few reports about the tool. OBJECTIVE:To compare the clinical efficacy of gap balance technique and measurement osteotomy technique under Offset Repo-Tensor in total knee arthroplasty,and explore the value of Offset Repo-Tensor in total knee arthroplasty. METHODS:The medical records of 85 patients with total knee arthroplasty were collected and divided into two groups according to the operation method.Group A consisted of 44 patients who underwent total knee arthroplasty using a gap balance technique combined with Offset Repo-Tensor.Group B consisted of 41 patients who underwent total knee arthroplasty using measurement osteotomy technique.Surgical time,American Knee Society Score,knee range of motion,changes in lower limb alignment,and postoperative complications were compared between the two groups to evaluate the clinical efficacy of gap balance technique combined with Offset Repo-Tensors in total knee arthroplasty. RESULTS AND CONCLUSION:(1)All 85 patients were followed up.(2)Postoperative knee range of motion in both groups was higher than that before surgery(P<0.05),and the improvement in group A was more significant than that in group B(P<0.05).(3)American Knee Society Score in both groups after surgery was higher than that before surgery(P<0.05),and the American Knee Society Score in group A was higher than that in group B at 2 weeks,1,3 months,and the last follow-up(P<0.05).(4)The operation time of group A was slightly shorter than that of group B,but the difference was not significant(P>0.05).(5)The lower limb alignment in both groups was improved after operation,but there was no significant difference between the two groups(P>0.05).(6)The complication rate of group A(2%)was lower than that of group B(7%),but there was no significant difference between the two groups(P>0.05).(7)It is indicated that compared with the measurement osteotomy technique,the combination of Offset Repo-Tensor and gap balance technique can elevate the clinical effect and improve the function and motion range of the knee joint.

Objective :
To observe the effect of hydrogen sulfide( H2 S) on the expression of transforming growth factor⁃β1(TGF⁃ β1) , E ⁃cadherin (E⁃CAD) , Vimentin (VIM) , alpha⁃smooth muscle actin ( α ⁃SMA) during epithelial⁃mesenchymal transformation(EMT) , and to explore the anti⁃fibrosis mechanism of it.
Methods :
Sixty rats ( male SD) were randomly divided into control group, bleomycin group, NaHS + bleomycin group and prednisolone + bleomycin group , 15 rats per group. 5 rats of each group were sacrificed at random in 7th , 14th and 28th day. The degree of alveolitis and pulmonary fibrosis was observed . The expression of protein and mRNA of TGF⁃ β1 , E ⁃cad , VIM , α ⁃SMA were determined by Immunohistochemi stry and RT⁃PCR.
Results :
① HE and Masson staining showed that the lung tissue of fibrosis had the lowest degree in control group. and the most severe in bleomycin group. The lung tissue of NaHS + bleomycin group and prednisolone + bleomycin group also had alveolitis and fibrosis changes , but the degree Were significantly less than bleomycin group. ② The mRNA and protein expression levels of TGF⁃ β1 , VIM and α ⁃SMA in bleomycin group, NaHS + bleomycin group and prednisolone + bleomycin group were all higher than that in control group at 7th , 14th and 28th day ( P < 0. 05 ) , while the expression levels of them in NaHS + bleomycin group and prednisolone + bleomycin group were all lower than that in bleomycin groupat each time (P < 0. 05) , which was significant at 28th day in NaHS + bleomycin. ③ The mRNA and protein expression levels of E ⁃Cad in bleomycin group, NaHS + bleomycin group and prednisolone + bleomycin group were all lower than that in control group at 7th , 14th and 28th day(P < 0. 05) , but the expression levels of E ⁃Cad in⁃NaHS + bleomycin group and prednisolone + bleomycin group were higher than that in bleomycin group at each time(P < 0. 05) , which was significant at 28th day in NaHS + bleomycin.
Conclusion
H2 S can reduce the degree of pulmonary fibrosis in rats , its mechanism may be related to the down⁃regulation of TGF⁃ β1and the inhibition of the EMT , which can enhance the expression of E ⁃cad and reduce the expression of TGF⁃ β1 , VIM and α ⁃SMA.

Objective To analyze the 10-year survival outcome and failure patterns for patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT),aiming to provide reference for optimized treatment for NPC.Methods Clinical data of 866 patients with NPC receiving IMRT from January 2001 to December 2008 were retrospectively analyzed.Survival analysis was performed using the Kaplan-Meier estimator.Univariate analysis was carried out by log-rank test and multivariate analysis was performed using Cox proportional hazards model.Results The median follow-up time was 132 months.The 10-year local recurrence-free survival (LRFS),distant metastasis-free survival (DMFS),progression-free survival (PFS) and disease specific survival (DSS) were 92.0%,83.4%,75.7% and 78.6%,respectively.A total of 210 patients died including 124 patients (59.0%) from distant metastasis,which was the primary cause of death,and 47 (22.3%) from local regional recurrence.Independent negative factors of DSS included age>50 years (P=0.00),LDH ≥ 245 IU/L (P=0.00),Hb< 120 g/L (P=0.01),T2-T4 staging (P=0.00),N1-N3 staging (P=0.00) and GTV-nx>20 cm3(P=0.00).The 10-year LRFS,DMFS and DSS of stage Ⅱ NPC patients did not significantly differ after IMRT alone and chemoradiotherapy (P=0.83,0.22,0.23).For patients with stage Ⅲ NPC,the 10-year LRFS and DSS in the chemoradiotherapy arm were significantly higher than those in the IMRT alone (P=0.01,0.01),whereas no statistical significance was observed in the DMFS between two groups (P=0.14).The overall survival of stage Ⅳa+Ⅳb NPC patients is relatively poor.Conclusions IMRT can improve the long-term survival of NPC patients.Distant metastasis is the primary failure pattern.Patients with stage Ⅰ-Ⅱ NPC can obtain satisfactory survival outcomes after IMRT alone.The addition of chemotherapy can further enhance the LRFS and DSS of stage Ⅲ NPC patients.However,the optimal therapeutic strategy remains to be urgently investigated for stage a+ Ⅳb NPC patients.

PURPOSE: The microRNA-34 (miR-34) family is important in tumor regulation. This study aimed to investigate the association of circulating miR-34 family proteins with clinicopathological features and their prognostic value in triple-negative breast cancer (TNBC) patients. MATERIALS AND METHODS: In this cohort study, 173 TNBC patients admitted to First People's Hospital of Shunde from May 1, 2009 to April 30, 2013 were enrolled. Meanwhile, 75 age-matched healthy women volunteers were identified as healthy controls (HCs). We examined the expression of miR-34 family (miR-34a/b/c) proteins in plasma collected from TNBC patients before any treatment was performed and from age-matched HCs using qPCR methods. RESULTS: The expressions of miR-34a/34b/34c were significantly lower in TNBC patients than in HC (p<0.001, p=0.027, p<0.001, respectively). miR-34a was correlated with tumor grade (p=0.038), lymph node positive (p=0.027), distant metastasis (p=0.004), and surgery (p=0.023); miR-34b was correlated with lymph node positivity (p=0.027); and miR-34c was correlated with tumor grade (p=0.017) and distant metastasis (p<0.001). Kaplan-Meier curve analysis displayed low expression of miR-34a as associated with worse overall survival (OS) (p=0.011), as well as miR-34c low expression (p=0.002). In addition, univariate and multivariate Cox proportional hazards regression was performed, and low expression of miR-34c (p=0.011) was found to be an independent risk factor for OS, as well as tumor grade (p=0.013), lymph node positive (p=0.050), and distant metastasis (p=0.021). CONCLUSION: In conclusion, this study demonstrated reduced miR-34a/c expression is highly associated with tumor progression and indicated worse prognosis. Also, miR-34c was an independent risk factor for OS in TNBC patients.

5."Discussion on the ""Four Mental Attitudes"" of Medical Practitioners"
Chinese Medical Ethics 2017;30(4):480-483
The construction of a harmonious hospital-patient relationship requires a sound medical system as a basis,but also the quality of both doctors and patients.For the medical practitioners,the following four medical attitudes is of great significance.The first is equanimity,which is taking the patient-doctor exchanges as equal relationship with choice and being chosen,providing services and accepting services.The second is responsibility,that is able to understand the dialectical relationship between rights and obligations correctly,and take the obligation they should take initiatively.The third is benevolence,that is full of mercy or sympathy towards the patients.The fourth is the heart of fear,that is able to respect their patients and treat the disease with fearand cautiousness because of knowing its ignorance.

Objective To establish an external quality assessment ( EQA) system of genitourinary tract secretions routine testing in Guizhou Province and improve the overall testing level.Methods From 2009 to 2011, more than 50 clinical laboratories in different grade hospitals from Guizhou Province were enrolled as participating units every year.EQA was carried out twice a year.Each time, five slides of high quality Wright′s or Gram stain smear of the genitourinary tract secretions or photographs obtained from these smears were selected to send to the participating laboratories for testing, and the feedback results from each laboratory were analyzed.The qualification was judged by the coincidence rate equal to or more than 80%. The average coincidence rates of each time and each year were statistically analyzed by Chi-squared test. Results From 2009 to 2011, the number of EQA participating units increased from 55 to 96, with an average return rate of >80%.Coincidence rates <80%of the 6 EQA results in the 3 years were as follow:four times for coccobacteria (73.7%,77.8%,61.1%,77.1%), twice for bacillus (75.6%,79.3%) and coccobacillus (64.3%,52.1%), once for infusorian (79.7%), epithelial cells (76.1%), neutropenia (75.7%) and cleanliness (71.3%).There were six batches of 30 quality assessment controls (accounting for 20.0%) in the six EQAs had the coincidence rate of <80%.Eleven items of 30 quality assessment controls with 1 to 15 batches were unqualified ( average coincidence rate of<80%) respectively.The item with the highest total average coincidence rate was suspected gonococcus (94.2%), and two items with the lowest total average coincidence rates were coccus and coccobacillus ( 77.0%, 75.2%, respectively ) . Conclusions This EQA program carried out within a certain range of clinical laboratories achieved good results:participating units increased significantly;the total score of all the items showed an obviously upward trend;the quality awareness of clinical lab technicians has enhanced to a certain extent.In this study, EQA system of genitourinary tract secretion routine testing were preliminarily established in Guizhou province, which provided a reference model of internal quality control ( IQC ) and EQA for clinical laboratories and higher authorities, and will be bound to have a positive impact on improvement of the overall level of genitourinary tract secretion routine testing.
