OBJECTIVETo investigate the short-term clinical outcome of unicompartmental knee arthroplasty for the treatment of spontaneous osteonecrosis of the knee.

METHODSFrom September 2013 to April 2014,5 patients with spontaneous osteonecrosis of the knee underwent unicompartmental knee arthroplasty, included 3 males and 2 females, aged from 65 to 80 years old with an average of 74 years. The courses of disease was from 1 to 6 years with the mean of 3 years. According to the radiographic staging criteria of Koshino, 1 case was stage II, 2 cases were stage III, 2 cases were stage IV. Clinical effects were assessed by VAS score, HSS score, and knee range of motion, tibiofemoral angle before and after operation.

RESULTSAll the patients were followed up from 6 to 7 months with an average of 6.4 months. All incisions obtained primary healing, and there were no complications such as infection, thrombosis, fracture of lower limbs. All 5 patients' pain relieved and their knee function improved significantly after operation, but knee range of motion had no obviously improved. Postoperative HSS scores, VAS scores, tibiofemoral angle were significantly improved than that of preoperative.

CONCLUSIONThe short-term effect of unicompartmental knee arthroplasty in treating spontaneous osteonecrosis of the knee is satisfactory.

Objective To explore the mechanism of anti-tumor effects of transferring tumor-specif-ic lymphocytes obtained from pre-immunized BALB/c mice with inactive rolL-21 tumor vaccine (mIL-21-Sp2/0)to syngeneic mice, associated with mIL-21 tumor vaccine immunization, in the condition of cyclo-phosphamide (Cy)-induced lymphopenia. Methods Activated lymphocytes of spleen and lymph nodes ob-tained from pre-immunlzed syngeneic mice with irradiated mIL-21-Sp2/0 cells were infused into BALB/cmice treated with Cy 2 days before, subsequently vaccinated with mlL-21 tumor vaccine, after 7 days, chal-lenged with Sp2/0 tumor cells, observed the growth of tumor of mice. T lymphocyte subsets differentiation was measured by flow cytometry (FCM) analysis. The proliferation and cytotoxie activities of activated lym-phocytes were analyzed by FCM, respectively, staining with CFSE and 7-AAD. The number of IFN-γ-secre-ting cells was evaluated by ELISPOT. Results The lymphopenic mice were transferred with activated lym-phocytes and inoculated with raiL-21 tumor vaccine might provide superior anti-tumor immunoprotection, re-tard tumor growth of the mice. The proliferating capabilities and killing rate of transferred tumor Ag-specific lymphocytes enhanced obviously, the number of IFN-γ-secreting cells was significantly higher compared with the control groups. Conclusion Under Cy-induced lymphopenia condition, tumor Ag-specific lymphocytes sensitized by raiL-21 tumor vaccine were transferred to mice and immunized with mlL-21 tumor vaccine at the same time, benefit the proliferation of transferred effective cells and immune cells itself, assist to form and sustain special anti-tumor effects.

Objective To investigate the effect of carotid artery stenting (CAS) on cognitive function in patients with asymptomatic severe carotid artery stenosis.Methods The patients with asymptomatic severe carotid stenosis (stenosis ≥ 70％) were enrolled in the study.The cognitive function evaluation was performed before CAS,1 and 3 months after procedure respectively with mini-mental status scale (MMSE),digital span (DS),Chinese auditory learning test (CALT),judgment of line orientation test (JLOT),and verbal fluency test (VFT),including attention,memory,visual spatial function,and frontal fluency function.Results A total of 26 patients with asymptomatic severe carotid artery stenosis who performed CAS were enrolled,18 were males and 8 were females (aged 52 to 79 years,mean 64.19 ±6.76 years),and the years of education was 9.84 ± 3.29 years.Eighteen patients had left carotid artery stenosis and 8 had contralateral carotid artery stenosis.CAS was performed successfully in all patients,and no complications occurred.Compared with the CAS before procedure,all the cognitive functions were improved significantly at 1 and 3 months after procedure (all P ＜0.01),however,there was no significant difference between 1 and 3 months after procedure (all P＞ 0.05).Conclusions CAS may improve cognitive function in patients with asymptomatic severe carotid artery stenosis,and it was more obvious in the early postoperative period.

Objective To explore the short-term effect of totally laparoscopic radical total gastrectomy with D2 lymph node dissection for treatment of local advanced upper gastric cancer. Methods Clinical data of 112 patients with local advanced upper gastric cancer who underwent totally laparoscopic or open radical total gastrectomy with D2 lymph node dissection in Affiliated Cancer Hospital of Shanxi Medical University from June 2016 to June 2018 were analyzed. The patients were divided into totally laparoscopic radical total gastrectomy with D2 lymph node dissection group (totally laparoscopic gastrectomy group, 54 cases) and open surgery radical total gastrectomy with D2 lymph node dissection group (opening gastrectomy group, 58 cases). The perioperative conditions and postoperative pathological conditions between the two groups were compared. Results All the 112 operations were technically successful. Compared with the opening gastrectomy group, the operating time of the totally laparoscopic gastrectomy group was longer [(240 ±47) min vs. (203 ±30) min], and the estimated blood loss was reduced [(103±21) ml vs. (260±34) ml], and the length of operative incision on body surface was shorter [(4.3±0.8) cm vs. (17.0±1.3) cm], and the differences between the two groups were statistically significant (all P< 0.05). There were no significant differences in the distance between the upper incision edge and tumor and the number of excised lymph node between the two groups (both P> 0.05). Compared with the opening gastrectomy group, the pain degree in 3-5 d after operation was slighter in the totally laparoscopic gastrectomy group, and the ratio of postoperative complications was lower, and the time of intestinal recovery and postoperative hospital stay was shorter, and the differences between the two groups were statistically significant (all P<0.05). Conclusion Totally laparoscopic radical total gastrectomy with D2 lymph node dissection for local advanced upper gastric cancer has advantages in operation safety, the time of postoperative recovery and the number of postoperative complications, and the effect of lymph node dissection can reach the level of open surgery.

OBJECTIVE: To compare the symptoms and lower airway inflammatory factors of patients with allergic rhinitis (AR), and to observe the effect of nasal irrigation in the treatment of allergic rhinitis. METHOD: Sixty-one cases diagnosed as AR after skin prick test (SPT)were selected and randomly divided into three groups: 17 patients in group A used nasal steroid spray; 21 cases in group B used nasal irrigation; 23 patients in group C combined ir rigation with nasal steroid. Before and after 3 months treatment, nasal visual analogue scale (VAS) score, rhino conjunctivtis quality of life questionnaire (RQLQ) score, fractional exhaled nitric oxide (FENO) values were observed and compared in each group. RESULT: Before treatment, there is no statistically difference between three groups (P > 0.05). After 3 months of treatment, VAS, RQLQ, FENO of all patients was significantly decreased (P < 0.05); VAS, RQLQ score was not significantly different among the three groups (P > 0.05), FENO value has no statistically significant difference between group A and group B (P > 0.05), but were less than that in group C (P < 0.05). CONCLUSION Nasal irrigation can ameliorate nasal symptoms, improve quality of life, decrease lower airway inflammation of allergic rhinitis patients. Nasal irrigation is an effective treatment of allergic rhinitis. Nasal irrigation combined with nasal steroid can achieve more significant efficacy.
