RESUMEN
Objective:To summarize the clinicopathologic features and clinical diagnosis and treatment experience of retroperitoneal paraganglioma.Methods:This study retrospectively analyzed the clinical, pathological and follow-up data of 39 patients admitted to the First Affiliated Hospital of Xi'an Jiaotong University from 1 Oct 2012 to 1 Oct 2022 for retroperitoneal paragangliomas undergoing resection.Results:There were 19 males and 20 females with tumor being functional in 11 cases (28%) and non-functional in 28 cases (72%). CT angiography showed that the tumors were distributed around the abdominal aorta and inferior vena cava in most cases. All 39 patients underwent tumor rescetion.Patients in laparoscopic group had shorter operation time and postoperative hospital saty compared with open sugery [(135±66)min vs. (194±67)min, t=-2.529, P=0.016; (6.6±2.2)d vs.(9.6±4.8)d, t=-2.096, P=0.043], while there was no statistically significant difference between the two groups in terms of intraoperative blood loss [(152±151)ml vs. (361±608)ml, t=-1.169, P=0.250]. There were no major postoperative complications in the laparoscopic group, and pulmonary infection in 1 case and intestinal obstruction in 1 case in the open group. Thrity-six cases were followed up, ranging from 2 to 115 months, 1 patient in the laparoscopic group died 1 year after surgery due to recurrence and metastasis. In the open group, 1 case recurred 2 years later and was discharged after the second operation, and 1 case died of recurrence 2 years after surgery. Conclusions:Surgery is indicated for retroperitoneal paraganglioma. Adequate perioperative management is the key to the success of the operation. Laparoscopic surgery is superior to open surgery in terms of operation time and postoperative recovery .
RESUMEN
【Objective】 To explore the application value of preoperative gastroscopic carbon nanoparticles labeling in patients undergoing laparoscopic radical gastric cancer surgery. 【Methods】 We included cases of laparoscopic radical gastric cancer surgery at The First Affiliated Hospital of Xi’an Jiaotong University from January 2017 to December 2019. Some cases received submucosal injection of carbon nanoparticles under the gastroscope before surgery. The effects of carbon nanoparticles labeling on the number of lymph nodes detected, operation duration and surgical complications were compared and analyzed. 【Results】 A total of 397 patients undergoing laparoscopic radical gastric cancer surgery were enrolled. Among them, 78 cases underwent gastroscopic carbon nanoparticles tracer labeling before operation. No complications were observed. The total number of lymph nodes detected by pathology after surgery in the carbon nanoparticles group significantly increased [(22.0(4.0) vs. 22.0(3.0), P=0.033)] while the operation time significantly reduced [(185.0±37.48)min vs. (213.4±23.66)min, P<0.001] compared with those in the control group. New gastric cancer lesions were revealed by gastroscopy in three cases (3.8%) of carbon nanoparticles labeling, and the original planned operation method was changed in two cases (2.6%). 【Conclusion】 Preoperative endoscopic carbon nanoparticles tracer labeling can not only help shorten the time of laparoscopic radical surgery for gastric cancer and increase the number of total lymph nodes detected for more accurate TNM staging, but also provide an opportunity for the discovery of synchronous multiple gastric cancer.

RESUMEN
Objective To evaluate the effects of probucol combined with atorvastatin medication on blood levels of oxidized low-density lipoprotein (ox-LDL), lipoprotein-associated phospholipase A2 (Lp-PLA2), and the correlation of their changes in patients with acute coronary syndrome (ACS) undergoing percutaneous poronary intervention (PCI). Methods A total of 97 patients with ACS and undergoing PCI were randomly divided into two groups according to the date of admission:single medication group (n=42),the patients were taken atorvastatin 20 mg/d; and combined medication group (n=55),the patients were taken atorvastatin 20 mg/d with probucol 500 mg/d. The plasma levels of ox-LDL and Lp-PLA2 were measured in both groups before and 6-8 weeks after the medication. Then the results were compared and analyzed between two groups. Results (1) Before treatment there were no significant differences in levels of ox-LDL and Lp-PLA2 between two groups (P>0.05). After the treatment, the ox-LDL level was significantly decreased in combined medication group (P<0.01). After the treatment, the levels of Lp-PLA2 were significantly decreased than those before treatment in both groups (P<0.01). Compared with single medication group, levels of ox-LDL and Lp-PLA2 were significantly lower in combined medication group (P < 0.01). (2) After treatment, the absolute value of Lp-PLA2 decline (ΔLp-PLA2) was positively correlated with the absolute value of ox-LDL decline (Δox-LDL) in combined medication group (r=0.314, P=0.020). Conclusion Probucol combined with statin therapy can reduce ox-LDL and Lp-PLA2 levels, and with a positive correlation between them. Probucol can further decrease the level of Lp-PLA2 by inhibiting ox-LDL production, which may be one of the mechanisms of its anti-atherosclerosis.

Objective To explore the influences of continued nursing care on the recovery of intra-articular fractures of joint function of limbs and the quality of life after operation. Methods A total of 493 intra-articular fracture of limbs postoperative patients,who were discharged from our department from January 2015 to December 2016,were randomly divided into observation group and reference group.After operation,the reference group used self-management mode to practice joint functional exercise,while the observation group uses continued nursing mode to guide physical therapy to recover joint functions.After they discharged 12 weeks,we compared these two groups of patients with satisfaction of nursing care,joint function recovery and quality of life. Results After 12 weeks of operation, in observation group, the patients' joint function recovery rate was close to 79.27%(195/246), which was significantly higher than the rates 55.47%(137/247)in reference group,the difference was statistically significant(χ2=32.947,P<0.01). Respectively, the physiological function score,vigor score, mental health score, physiology role score, body pain score, health condition score, social function score and health score of the observation group in the quality of life assessment were (72.66 ± 4.41), (89.27 ± 4.10), (93.01 ± 3.05), (88.03 ± 3.19), (91.68±3.99),(76.78±4.86),(79.11±4.68),(85.57±7.07).The scores of control groups were(65.71±3.41),(64.02±4.51),(61.43±4.29),(66.49±4.52),(64.24±4.30),(62.02±6.24),(62.94±4.50),(65.02±7.72).The comparative difference of the two groups has statistical significance (t=12.48- 60.15, P<0.05). Meanwhile,in the satisfaction rate of nursing care,the great satisfaction rate of observation group(70.73%, 174/246) was much higher than reference group (37.65%, 93/247), the difference was statistically significant (χ2=59.789, P<0.01). Conclusion Offered outside continued nursing care to the intra-articular fracture of limbs postoperative patients can effectively improve the joint function of patients,their qualities of life and can considerably increase satisfaction of nursing care. Thus,it should to be clinically promoted.

ABSTRACT:Objective To investigate the effects of ω-3 polyunsaturated fatty acids on the proliferation of human gastric cancer cell line AGS and the possible mechanisms.Methods Human gastric cancer line AGS and human microvascular epithelial cell HMEC-1 were treated with different concentrations of docosdhexaenoic acid (DHA)and eicosapentaenoic acid (EPA).The inhibition of cell proliferation was evaluated by MTT assay and cell morphology.Flow cytometry was used to detect the cell cycle change.The expressions of mitochondrial respiratory membrane protein complex Ⅰ,Ⅱ and V were analyzed with Western blot.Results DHA and EPA could markedly inhibit the proliferation of AGS in significant time-dependent and concentration-dependent manners (P 0.05).Conclusion ω-3 PUFAs can selectively inhibit the growth and proliferation of human gastric cancer cell line AGS.These effects may be as-sociated with arresting cell cycle in G0/G1 phase and inhibiting the energy metabolism of AGS cells.
RESUMEN
BACKGROUND:It is an important issue of alveolar ridge preservation after tooth extraction. Because of the limited treatment and geographical conditions, lack of awareness of oral health, many local people in frontier areas in Xinjiang have poor alveolar ridge that is not of timely repair after tooth extraction. Thus, it is important to find a suitable local and efficient way to save the residual ridge, which has a more practical clinical value. OBJECTIVE:To investigate the feasibility of nano-colagen artificial bone used for alveolar ridge preservation in the Kazakh in Xinjiang Tacheng Region, China. METHODS: Sixty-eight Kazakh patients with bilateral extraction from Tacheng region, Xingjiang Uygur Autonomous Region, China were selected in a self-controled trial. According to the principle of a minimum alocation imbalance index, the experimental side and control side of extraction patients were confirmed. In the experimental side, nano-colagen artificial bone was implanted; while, conventional treatment was done in the control side. Multi-slice spiral CT was used to scan the regions of extraction interest to measure the relative gray value of alveolar bone mineral density immediately and 3 months after implantation. RESULTS AND CONCLUSION:Immediately after implantation, tooth extraction sockets were visible on CT images both in the experimental and control sides; but after 3 months, the extraction sockets became unclear on the CT images, and CT values were close to those of the surrounding alveolar process, but bone tissues were ful of the bone graft area in the experimental side. The alveolar bone mineral density was higher in the experimental side than the control side at 3 months after implantation. These findings indicate that the nano-colagen artificial bone has good clinical achievement in alveolar ridge preservation in the Kazakh in Xinjiang Tacheng Region.
RESUMEN
Objective To investigate the inhibitory effects of docosahexaenoic acid (DHA)and 5-fluorouracil (5-FU)in combination on human gastric cancer cell line AGS in vitro .Methods Human gastric cancer line AGS was treated with different concentrations of DHA and 5-FU alone or in combination.The inhibition of cell proliferation was evaluated by MTT assay.Dose of median (IC50 )of drugs (alone or in combination)and the combination index (CI)were calculated using the median-effect equation and the combination index equation of Chou-Talalay.Flow cytometry was used to detect the cell cycle distribution.The expression of mitochondrial respiratory membrane protein complex in AGS cells was analyzed with Western blot.Results DHA and 5-FU alone or in combination could markedly suppress the proliferation of AGS in significantly time-dependent and dose-dependent manners (P <0.05).IC50 values with DHA or 5-FU administered for 24 h and 48 h were 5 1.60 μg/mL (DHA:24 h),34.82 μg/mL (DHA:48 h),45.90 μg/mL (5-FU:24 h),and 1 6.86 μg/mL (5-FU:48 h), respectively.DHA remarkably strengthened the inhibitory effect of 5-FU and decreased IC50 of 5-FU by 3.56 -2.1 5 folds.The combination of DHA and 5-FU showed synergism.Flow cytometry showed that AGS cells treated with DHA and 5-FU were arrested in G0/G1 phase and the proportion of AGS cells in G0/G1 phase increased compared with that in the control group,DHA group and 5-FU group,while the proportion of the cells in S phase decreased significantly (P < 0.05 ).Western blot showed after treatment with DHA and 5-FU for 48 h,the expression of mitochondrial respiratory membrane protein complex was significantly decreased compared with control group,DHA group and 5-FU group (P <0.05).Conclusion DHA could act synergistically with 5-FU in inhibiting the growth of gastric carcinoma cells,and meanwhile decrease the dose of 5-FU.The mechanism may be associated with cell cycle arrest in G0/G1 phase and interference in the energy metabolism of AGS cells due to inhibition of the expression of mitochondrial oxidative respiratory chain complexes by the two compounds.

Objective To observe the outcomes of the modified multiple nerve transfer s combined with the late hand function reconstruction to restore the active pick-up function of the paralyzed upper extremity in patients with total brachial plexus avulsion injuries (TBPAI).Methods 33 patients suffered with TBPAI firstly underwent multiple nerve transfers,which including accessory nerve transfers to neurotize the suprascapular nerve to recover the shoulder abduction,contralateral C7 (CC7) nerve transfers via the modified pre-spinal route with direct coaptation to restore lower trunk function and the musculocutaneous nerve was also neurotized by the transferred CC7 nerve via a cutaneous nerve graft to restore the function of elbow flexion,as well as the phrenic nerve transfers to neurotize the posterior division of lower trunk to restore the function of elbow and finger extension.The patients with muscle recovery were selected to perform the hand function reconstruction at the second stage for restoring the active pick-up function.The patients were chosen as followcriterias:the degree of shoulder abduction attained 30°or more,the motor power of elbow,wrist,and finger flexion attained grade M4 or more,elbow and finger extension attained M3 or more.The methods of hand function reconstruction included wrist fusion and flexor carpal ulnaris opponensplasty,in addition to palmar capsulodesis of the metacarpophalangeal joint.Results The mean follow up was 41±7.7 (range,36-73 months) after the first procedure of multiple nerve transfers,the muscle strength of elbow and finger and wrist flexion attained M 4 as well as the elbow and finger extension achieved M3 or more in 10 patients,all of 10 patients achieved 40°-80°shoulder abduction.8 out of 10 patients had performed the second surgical procedure for hand functional reconstruction.6 of them had successfully recovered the active pick-up function.Conclusions The newly designed procedure of multiple nerve transfers could effectively restore the function of shoulder abduction,elbow,wrist,and finger flexion,as well as elbows and finger extension in patients with TBPAI,combined with the hand functional reconstruction,active pick-up function could be successfully reconstructed.
RESUMEN
Objective: To investigate the expression of α-B crystalline in triple-negative breast cancer (TNBC) and discuss its role in the prognosis and targeted therapy of TNBC by analyzing the correlation amongα-B crystalline and the clinico-pathological indi-ces of breast cancer. Methods:Immunohistochemistry SP assay was used to determineα-B crystalline expression in paraffin-embedded specimens of 30 cases of TNBC and 50 cases of non-TNBC tissues. The differences in protein expressions among tissues were com-pared, and correlation analysis was performed to determine the relationship between protein expression and clinico-pathological indi-ces. Results:The positive expression rate ofα-B crystalline was 66.67%in TNBC (20/30) and 42.00%in non-TNBC (21/50), which in-dicates that the expression is significantly higher in TNBC than in the non-TNBC tissues (χ2=4.566, P0.05), but exhibits a differ-ence in terms of lymph node metastasis and the number of metastasized lymph nodes [P53, Ki67 (P0.05). Conclusion:Significant differences were found inα-B crystalline expression between TNBC and non-TNBC.α-B crystalline is highly expressed in TNBC tissues, and the expression is signif-icantly higher in TNBC tissues than that in non-TNBC tissues.α-B crystalline is associated with poor prognosis of breast cancer. Conse-quently, the overexpression ofα-B crystalline in TNBC may be a reason for unfavorable TNBC prognosis.
