ABSTRACT

The anterior cruciate ligament (ACL) reconstruction mostly relies on the experience of surgeons. To improve the effectiveness and adaptability of the tension after ACL reconstruction in knee joint rehabilitation, this paper establishes a lateral force measurement model with relaxation characteristics and designs an on-line stiffness measurement system of ACL. In this paper, we selected 20 sheep knee joints as experimental material for the knee joint stability test before the ACL reconstruction operation, which were divided into two groups for a comparative test of single-bundle ACL reconstruction through the anterolateral approach. The first group of surgeons carried out intraoperative detection with routine procedures. The second group used ACL on-line stiffness measurement system for intraoperative detection. After that, the above two groups were tested for postoperative stability. The study results show that the tension accuracy is (- 2.3 ± 0.04)%, and the displacement error is (1.5 ± 1.8)%. The forward stability, internal rotation stability, and external rotation stability of the two groups were better than those before operation (

ABSTRACT

The laparoscopic vision platform developed from the prototype of candlelight reflector device to HD, 3D and 4K ultra HD, which revolutionized surgery from open surgery to minimally invasive surgery. With the continuous application in gastric cancer surgery, the importance of laparoscopy in radical gastrectomy is gradually recognized. Radical gastrectomy mainly includes lymph node dissection and digestive tract reconstruction. The reconstruction of digestive tract after radical gastrectomy for distal gastric cancer has been a hot topic of discussion and research, which is directly related to the incidence of postoperative complications, nutritional status and quality of life. This paper mainly discusses the Roux-en-Y digestive tract reconstruction of radical gastrectomy for distal gastric cancer with 4K laparoscopic.

ABSTRACT

According to the current evidence-based medicine researches, the eastern and western countries have reached a consensus that D2 operation is a standardized procedure for advanced gastric cancer.However, the postoperative five-year survival rate is still not satisfactory. Professor Gong Jianping of Tongji Hospital, Tongji Medical Gollege of Huazhong University of Science and Technology proposed a theory of membrane anatomy (the third element of surgical anatomy) and the concept of cancer leakage—an epoch-making concept in surgical anatomy. The Department of Gastrointestinal Surgery, The Affiliated Hospital of Guizhou Medical University was honored to be selected as one of the first domestic replication units of 3D laparoscopic radical gastrectomy under membrane anatomy. Professor Gong Jianping has visited our hospital several times for surgical demonstration, explanation of membrane anatomy theory and replication training. Through the understanding of membrane anatomy theory, we found that 3D laparoscopic radical gastrectomy guided by membrane anatomy can achieve good results, e.g less bleeding, complete resection, complete lymph node dissection and avoidance of side damage, meanwhile the operation is simple and safe. At the same time, it can avoid the shedding of cancer cells, so as to reduce the iatrogenic leakage of cancer and improve the efficacy of radical gastrectomy. In addition, the standardized procedure of laparoscopic radical gastrectomy makes it scientific, reproducible and easy to be popularized.

ABSTRACT

OBJECTIVE To explore the possible role and mechanism of vitamin D on the pathogenesis of allergic rhinitis by adjuvant therapy with vitamin D3. METHODS A total of 60 allergic rhinitis patients and 30 healthy subjects were selected as the combination therapy group, standard treatment group and control group. Vitamin D3 nasal drops to nasal cavity and oral Desloratadine Citrate Disodium at the same time 8.8 mg once a day were given in combined treatment group patients. Standard treatment group patients received oral Desloratadine Citrate Disodium 8.8 mg once a day. The total course of treatment was 4 weeks and then to assess the changes of serum 25(OH)D concentration, eosinophils, IL-4 levels and the therapeutic effect before and after treatment. RESULTS The serum 25(OH)D levels before and after treatment in combination therapy group were(23.67±4.47)ng/ml and (47.57±2.83)ng/ml, the IL-4 levels were (14.576 ± 4.472)pg/ml and (10.381 ± 3.41l)pg/ml, and the eosinophils of peripheral blood counts were (0.71±0.14)× 109/L and (0.34 ± 0.09)×109/L. The total effective rate was 97%. The serum 25(OH)D levels before and after treatment in standard treatment group were (23.42±3.83)ng/ml and(31.51 ±2.95)ng/ml, the IL-4 levels were (15.187±5.144)pg/ml and (12.794 ±5.396)pg/ml, and the eosinophils of peripheral blood counts were (0.67±0.12)×109/L and (0.41 ±0.10)×109/L. The total effective rate was 84%. CONCLUSION Nasal vitamin D3 drops combined with antihistamines for allergic rhinitis can effectively improve the clinical symptoms and reduce the related inflammatory markers.

ABSTRACT

Objective To investigate the effect of Aurora-A kinase inhibitors VX-680 on the proliferation of thyroid carcinoma cell and to study their molecular mechanism. Methods The undifferentiated thyroid carcinoma cells were divided into groups of VX-680 with different drug concentration. Drug effect was observed by MTT method to measure the changes of cell proliferation. The gene expression of Aurora-A , Bcl-2 and Bax were tested by immunofluorescence assay. Results MTT results showed cell proliferation had been suppressed obviously with the of concentration increase of drug and the duration of administration (P 0.05). Conclusions Aurora-A and Bcl-2 protein expression of thyroid cancer are inhibited when VX-680 being used , at the same time , Bcl-2/Bax scale value loses balance to accelerate forming Bax/Bax homodimer. Thus cancer cell proliferation is blocked and cell apoptosis is induced. So VX-680 is a good target inhibitor for anaplasia thyroid cancer.

ABSTRACT

Objective To evaluate the effect of external application therapy combined with chiropractic therapy on the pediatric asthma.Methods A total of 55 patients were randomly assigned into the treatment group (28 patients) and the control group (27 patients), The treatment group was treated with external application therapy combined with chiropractic therapyin the the hottest and coldest weather of each year; while the control group was only treated with chiropractic therapy. Both groups were treated for 3 years. After the treatment, the total effective rate, the clinical control rate, and the frequency of asthma attacks were detected.Results The total effective rate was 92.9% (26/28) and the clinical control rate was 64.3% (18/28) in observation group, which were better than those of 70.4% (19/27) and 22.2% (6/27) in the control group (χ2=4.073,P=0.044, andχ2=8.823,P=0.003). After 3 years’ treatment, the asthma grading distributionin the treatment group was significantly different from the control group (χ2=10.776,P=0.005). The frequency of asthma attacks in the treatment group after the first year treatment (4.5 ± 0.5 timesvs. 5.0 ± 0.5 times,t=3.708,P<0.01) was significantly lower than that in the control group; so did the second years after treatment (3.0 ± 0.5 timesvs.4.3 ± 0.5 times,t=9.728,P<0.01), and the third years (1.5 ± 0.5 times vs. 3.0 ± 0.5 times,t=11.225,P<0.01).ConclusionsThe external application therapy combined with chiropractic therapy could prevent asthma in children patients.

ABSTRACT

Objective: To investigate changes of quality of life [QOL] of patients with adenocarcinoma of the esophagogastric junction [AEG] after gastric tube anastomosis


Methods: From January 2009 to December 2011, eighty-seven patients with Types II and III AEG were selected for gastric tube reconstruction after proximal gastrectomy. The QOL of the patients was assessed using the Chinese versions of the EORTC QLQ-C30 and the EORTC QLQ-STO22 preoperatively, as well as one and two years postoperatively


Results: The QLQ-C30 showed that the global health of the respondents decreased at one year after the surgery [P=0.02]. The preoperative score for physical function was significantly better than the one- and two-year post-operation scores. The preoperative scores for pain, nausea and vomiting, and economic difficulties were worse than the one- and two-year post-operation scores [P < 0.05]. Diarrhea was worse at one year post-operation than during pre-operation [P = 0.00], but improved at two years after the operation. The QLQ-STO22 scales showed that the preoperative dysphagia score was better than one-year post-operation, and no significant differences were observed in terms of dysphagia between the preoperation and two-year postoperative periods. Preoperative reflux and taste scores were better than those after the operation [P < 0.05]. The hair loss score at one-year post-operation was worse than at either pre-operation or two-year post-operation


Conclusions: Most QOL scales worsened after surgery, particularly at postoperative year one. However, the scales can be gradually recovered to preoperative levels. The physical function, nausea and vomiting, reflux, taste, and financial difficulties did not fully recover two years after the operation

ABSTRACT

This study investigated the expression and clinicopathological significance of CD9 in gastrointestinal stromal tumor (GIST). Immunohistochemistry staining for CD9 was performed on tumor tissues from 74 GIST patients. The correlation with clinicopathological features, risk classification and prognosis was analyzed. CD9-positive staining comprised 59.5% (44/74) of the GIST patients. The CD9-positive expression rate of the sample was significantly associated with diameter (P = 0.028), mitotic counts (P = 0.035), risk classification (P = 0.018) and three-year recurrence-free survival (RFS) (P < 0.001). Cox proportional hazards regression (HR = 0.352; P = 0.015) showed that CD9 is an independent factor for post-operative RFS. The subgroup analysis showed that CD9 expression in gastric stromal tumor (GST) is significantly associated with diameter (P = 0.031), risk classification (P = 0.023) and three-year RFS (P = 0.001). The Cox proportional hazards regression (HR = 0.104; P = 0.006) also showed that CD9 is an independent factor for RFS of GST. However, CD9 expression does not have a statistically significant correlation with clinicopathological features, risk classification, and prognosis in non-GST. In conclusion, CD9 expression in GIST appears to be associated with the recurrence and/or metastasis of GIST patients, especially in GST, which may indicate the important role of CD9 in the malignant biological behavior and prognosis of GST.

ABSTRACT

Objective To study the protective function and the mechanism of Shenqi Dihuang decoction on the kidney of type 2 diabetes melltuds rats. Methods Type 2 diabetes mellitus rat models were set up by injection of small dose of streptozotocin (STZ). The SD rats were randomized into a control group, a model group and a treatment group. The treatment group was given Shenqi Dihuang decoction. The control group and the model group were given the same amount of water. After 24 weeks, renal morphology examination and biochemical indicator were examined. The levels of Ang-Ⅱ and endothelin (ET) in senum were tested by radioimmunoassay and the level of transforming growth factorβ1 (TGF-β1) in renal cortex were determined by immunohistochemistry. Results The kidney function and kidney lesions were significantly improved in the treatment group than in the model group. Ang-Ⅱ And ET levels in serum and renal cortex was reduced, and the expression of TGF-β1 in the treatment group was decreased. Conclusion Shenqi Dihuang Decoction has protective effect on the kidney of diabetic rats, the mechanism may be related to its inhibition on the over expression of Ang- Ⅱ, ET and TGF-β1.
