Objective To study the relationship between the type of histopathology and prognosis of contained mucous adenocarcinoma(CMAC) of stomach and its clinical significance. Methods Eighty-seven cases of CMAC of stomach were observed by means of pathomorphology, histochemistry, immunohistochemistry and follow up etc. Results The malignant behavior of the cancer was significant difference according to the nature and quantity of the CAMC and the primary pathological type of the cancer.The clinical type in simple mucous carcinoma was mainly Borrmann type I;in tubular papilla mucous adenocarcinoma was mainly Borrmman type II; in signet-ring cell mucous carcinoma was mainly Borrmman type IV,and in mixed cell mucous carcinoma was mainly Borrmman type III. There was significant difference in the lymphatic metastasis and survival rate between the 4 groups. Conclusions Correct differentiation of the pathological type of contained mucous adenocarcinoma of stomach is important for guading the treatment and predicting the prognosis.Cathepsin D expression can help for understanding the biological behavior of CMAC of the stomach.

Objective To discuss the treatment of periprosthetic femoral fractures (PFF) with unstable prosthesis by replacement of long-stem femoral prosthesis and internal fixation.Methods From December 2005 to December 2014,15 PFF patients with unstable prosthesis (15 hips) following were treated at our department.They were 10 men and 5 women,aged from 64 to 89 years (mean,76.2 years).Their primary surgeries included total hip arthroplasty in 13 cases and biological bi-polar replacement of femoral head in 2.Two prostheses were cement and 13 biological.By Vancouver classification,9 cases were type B2,and 6 type B3.The unstable prostheses in the 15 cases were replaced by long-stem femoral ones,followed by internal fixation.At the last follow-ups,clinical outcome were evaluated by Harris scoring and images of PFF by Beals & Tower criteria.Complications were documented.Results One died 4 months after operation.The other 14 patients were followed up for an average of 4.5 years (from 6 months to 9 years).Fracture union was achieved in 12 cases after an average of 3.9 months (from 3 to 9 months).Nonunion occurred in 2 cases.Imaging evaluation revealed 9 excellent cases,3 good ones and 2 poor ones.The Harris scores at the last follow-up averaged was 82.3 points (from 50 to 100 points).Deep vein thrombosis occurred preoperatively in one case and posterior tibial vein thrombosis occurred in 2 cases respectively on day 3 and day 10 postoperatively.No such complications occurred as malunion,fixation failure,dislocation or prosthesis loosening.Conclusion Satisfactory outcomes can be achieved by replacement of long-stem femoral prosthesis combined with appropriate fixation for treatment of PFF with unstabrosthesis.

BACKGROUND:There are many complications of limb salvage surgery in patients with osteosarcoma of the middle tibia, and the limb salvage surgery is one of the current difficulties in clinical treatment. OBJECTIVE:To evaluate the clinical efficacy of reconstruction with massive al ograft bone for osteosarcoma of the middle tibia by retrospectively reviewing relevant cases. METHODS:Seven patients with osteosarcoma of the middle tibia were treated. And we analyzed their clinical data retrospectively. Al patients completed the formal preoperative adjuvant chemotherapy and we confirmed that there was no distant metastasis before surgery. Al patients received large al ogeneic bone transplantation and internal fixation, and the gastrocnemius muscle flap coveraged graft bone in surgery. The average length of al ogeneic bone was 12.5 cm. Five patients received postoperative adjuvant chemotherapy completely, and two patients received partly. RESULTS AND CONCLUSION:The fol ow-up period was 18-36 months. One patient had local tumor recurrence at 1 year after transplantation, and died of lung metastases after amputation. One patient survived after resection of lung metastases that occurred at 1.5 years after transplantation. One patient died of lung metastases at 2 years after transplantation. The rest four patients were tumor-free. The mean Musculoskeletal Tumor Society (MSTS) score was 26.5, the mean International Society of Limb Salvage (ISOLS) graft score was 31. Among four underage patients, one had leg length deformities, with limb shortening 2 cm. There were no postoperative infections and pathological fractures. Using large al ogeneic bone for the repair of bone defects after tumor surgery of the middle tibia can have a good clinical efficacy under the premise of strict indications. Using gastrocnemius muscle flap to cover the bone graft during surgery is an effective measure to reduce postoperative complications.

Objective:To investigate the effects of tranexamic acid on the drainage duration after primary unilateral total knee arthroplasty (TKA).Methods:From June 2017 to December 2018, a total of 182 patients (42 males and 140 females) who underwent primary TKA were included. The age of patients was 68.1±7.1 years (60-76 years). According to the random number table, the subjects were divided into four groups: 45 cases in tranexamic acid group 1 (TXA1), 46 cases in tranexamic acid group 2 (TXA2), 46 cases in tranexamic acid group 3 (TXA3) and others in none tranexamic acid group (NTXA). The patients in TXA1-3 groups received intravenous infusion combined with local application of tranexamic acid. The patients in NTXA group were locally perfused in the joint cavity with 100 ml normal saline after surgery. The drainage volume, total blood loss, invisible blood loss, degree of postoperative joint swelling, Hospital for Special Surgery (HSS) and visual analogue scale (VAS) of pain were compared among the four groups.Results:The postoperative drainage volume of TXA1-3 groups was 85.5±34.3 ml, 189.4±72.3 ml and 215.3±93.4 ml, respectively, which were less than that of the NTXA group (351.3±113.5 ml) with significant difference ( F=11.5, P=0.005). The postoperative drainage volume of TXA1 group was less than that of TXA2-3 groups. The total postoperative blood loss was 699.0±255.7 ml, 710.4±296.1 ml, and 715.8±248.2 ml in the TXA1-3 groups, respectively, which were less than that of the NTXA group (1 130.5±354.2 ml) with significant difference ( F=13.1, P=0.001). At the 4th day after TKA, the knee swelling degree of TXA1-3 groups was 1.25±0.07, 1.13±0.12, and 1.12±0.13, respectively, which were less severe than that of the NTXA group (1.43±0.22) with significant difference ( F=8.23, P=0.015). There were 2 cases with positive bacterial culture in NTXA group and TXA3, 3 cases with hematoma and 1 case with delayed wound healing in the NTXA group. Conclusion:The application of tranexamic acid after TKA can reduce postoperative drainage volume, latent blood loss and total blood loss. The removal of the drainage at 18 h after the operation can not only drain completely, relieve pain and promote knee joint function, but also effectively reduce the risk of infection associated drainage.

Objective:To establish a colon cancer cell line which overexpressing LINC01018 stably and study its biological characteristics.Methods:The expression of LINC01018 in HCoEpiC and HT-29 cells were detected by real time fluorescence quantitative polymerase chain reaction (qRT-PCR). HT-29 cells were infected with LINC01018 overexpression lentivirus to screen and establish HT-29 cell lines which overexpressing LINC01018 stably. The effect of LINC01018 on the proliferation, invasion and migration of HT-29 cells were detected by cell counting kit-8 (CCK-8) assay and Transwell assay separately. The expression of CDK6 and matrix metalloproteinase-2 (MMP-2) in HT-29 cells was detected by Western blot.Results:The expression of LINC01018 in HT-29 cells was significantly lower than that in the human colonic epithelial cells (HCoEpiC). HT-29-L18 cell lines which overexpressing LINC01018 stably was screened successfully. Overexpression of LINC01018 significantly inhibited the cell proliferation, invasion and migration, and reduced the protein expression of CDK6 and MMP-2 in HT-29 cells.Conclusions:The expression of LINC01018 was decreased abnormally in colon cancer cells. Up-regulation of LINC01018 expression can inhibit the proliferation, invasion and migration of colon cancer cells, which may be related to CDK6 and MMP-2.

Drug therapy is a common method to cure diseases and relieve symptoms.The value of patient-reported outcome(PRO)in evaluating the effect of drug therapy has been increasingly paid attention.The PRO scale is a standardized questionnaire,which can scientifically evaluate the experiences and subjective effects of drug use from a patient-centered perspective,and help patients and clinicians make more reasonable medication decisions.By reviewing and sorting out relevant global literature,this paper found that the content of the PRO scales relevant to drug therapy focused on five fields:"medication satisfaction""medication adherence""drug treatment burden""medication-related quality of life"and"adverse drug reactions".This paper described the basic information,measurement characteristics and application of common scales in recent years respectively,and summarized and analyzed the problems and enlightenment of scale development,aiming to provide theoretical reference for the selection,application and development of PRO scales.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.

Objective: To verify the safety and efficacy of IONTRIS particle therapy system (IONTRIS) in clinical implementation. Methods: Between 6.2014 and 8.2014, a total of 35 patients were enrolled into this trial: 31 males and 4 females with a median age of 69 yrs (range 39-80). Ten patients had locally recurrent head and neck tumors after surgery, 4 cases with thoracic malignancies, 1 case with hepatocellular carcinoma, 1 case with retroperitoneal sarcoma, and 19 cases with non-metastatic prostate carcinomas. Phantom dose verification was mandatory for each field before the start of radiation. Results: Twenty-two patients received carbon ion and 13 had proton irradiation. With a median follow-up time of 1 year, all patients were alive. Among the 16 patients with head and neck, thoracic, and abdominal/pelvic tumors, 2, 1, 12, and 1 cases developed complete response, partial response, stable disease, or disease progression, respectively. Progression-free survival rate was 93.8% (15/16). Among the 19 patients with prostate cancer, biological-recurrence free survival was 100%. Particle therapy was well tolerated in all 35 patients. Twenty-five patients (71.4%) experienced 33 grade 1 acute adverse effects, which subsided at 1 year follow-up. Six (17.1%) patients developed grade 1 late adverse effects. No significant change in ECOG or body weight was observed. Conclusions IONTRIS is safe and effective for clinical use. However, long term follow-up is needed to observe the late toxicity and long term result.
