ObjectiveTo investigate the expressions of folate receptor alpha (FOLR1) in 40 esophageal cancerous tissues and its relevance of ABO blood group.MethodsABO blood groups were analyzed in 40 patients.Immunohistochemistry (IHC) and real-time quantitative reverse transcription PCR detection were used to detect the expression of folate receptor in cancer and adjacent tissues.Results20％of esophageal cancer was suspected positive (+), 50％ of cancer adjacent tissue was suspected positive (+), 10％ were positive (+), the difference was statistically significant (x2 = 14.48, P ＜0.01).Real Time RT-PCR analysis showed FOLRI low expression in esophageal cancer and adjacent tissues, compared to normal esophageal mucosa, the differences were statistically significant (F1 =53.247, F2 = 116.500, P ＜0.01).ABO blood type and FOLRi in esophageal cancer patients were not significant correlated (P =0.647, P ＞0.05).ConclusionsFOLRI expression was decreased in the esophageal lesions compared with adjacent tissues.Detection of FOLRl expression level in esophageal cancerous tissues and the paired adjacent tissues was helpful for judging the extent of disease and guiding surgery treatment.The FOLRI expression level in esophageal carcinoma tissues had no relationship with ABO blood types.

OBJECTIVE: To review the technical details of retroperitoneoscopic ureterolithotomy and evaluate the clinical effect. METHODS: Between June 2004 and December 2008, 69 patients (55 males and 14 females) with upper ureteral calculus received retroperitoneal laparoseopic ureterolithotomy (40 left sides and 29 right sides). The stone size ranged from 1.5 to 3.1 cm [(2.2±0.6) cm]. RESULTS: All the patients underwent retroperitoneoscopic ureterolithotomy. The operation time was 40-295 (63.1±19.8) min,and the blood loss was 30-150 (57.2±23.0) mL.The hospital stay was 5-8 (6.7±1.3) d. During the followup, there was neither ureteral stricture nor recurrent calculus. CONCLUSION Retroperitoneoscopic ureterolithotomy is safe, effective and minimally invasive, which may replace the conventional open surgery.

Objective To explore the mechanism of immediate effect regulated by acupuncture on acupoints in patients with migraine without aura(MwoA)during the interictal period.Methods A total of 28 MwoA patients were enrolled and resting-state functional magnetic resonance imaging(rs-fMRI)were performed at baseline and after acupuncture for 30 minutes.Paired t test was used to compare the differences of regional homogeneity(ReHo)and voxel-mirrored homotopic connectivity(VMHC)between two groups.Additionally,the correlation between the changes of rs-fMRI indexes and clinical scores was analyzed.Results In MwoA patients after acupuncture for 30 minutes,the mean regional homogeneity(mReHo)was decreased in the right lingual gyrus and right cere-bellum and was increased in the right middle frontal gyrus,while the z transformation voxel-mirrored homotopic connectivity(zVMHC)was significantly decreased in the bilateral cuneus compared with baseline.There was no significant correlation between imaging data and clinical scales.Conclusion Patients with MwoA after acupuncture for 30 minutes show abnormal ReHo and VMHC in multiple brain regions,which suggest that the mechanism of immediate effect may act through regulating pain-related brain regions.

ObjectiveTo investigate the mechanism of acupuncture in the treatment of chemotherapy-related cognitive impairment （CRCI） of breast cancer based on resting-state functional magnetic resonance imaging （rs-fMRI）. MethodTwenty-five patients with CRCI of breast cancer were included and treated with the acupuncture based on the method of regulating qi and blood， nourishing mind and benefiting intelligence； the selected acupoints included Zusanli （ST 36， bilateral）， Xuehai （SP 10， bilateral）， Tanzhong （CV 17）， Zhongwan （CV 12）， Qihai （CV 6）， Baihui （GV 20）， Fengfu （GV 16， bilateral）， Xinshu （BL 15， bilateral）， Tongli （HT 5， bilateral）， Zhaohai （KI 6， bilateral）， Yixi （BL 45， bilateral） twice a week， each time interval of 2-3 days， for 8 weeks. The scores of Montreal Cognitive Assessment （MoCA）， Mini-mental State Examination （MMSE）， European Cancer Research and Treatment Organization Quality of Life Questionnaire （EORTC QLQ-C30） were compared before and after acupuncture， and the effectiveness were evaluated by MoCA scale. The patients received rs-fMRI before and after treatment， and used low-frequency oscillation amplitude and functional connectivity （FC） analysis to extract the mean zALFF values of regions of interest such as bilateral anterior cingulate gyrus， bilateral hippocampus， bilateral amygdala， bilateral temporal pole middle temporal gyrus， and bilateral temporal pole supramarginal gyrus for comparison， and used the brain regions with statistically significant differences in the pre- and post-treatment zALFF values as the seed points for the seed-point-based FC Analysis. Correlation analyses were performed between the imaging metrics and the clinical scales. ResultsTwenty-four patients with CRCI of breast cancer completed treatment and follow-up. The zALFF values of the left hippocampus， left amygdala， and left temporal pole temporal gyrus in patients' rs-fMRI decreased after treatment （P＜0.05 or P＜0.01）， and left temporal pole temporal gyrus and right posterior cerebellar lobe FC were elevated （t = -5.169）， and MoCA scale total scores and visuospatial and executive， naming， and delayed recall cognitive scores， MMSE scale total scores， and EORTC QLQ-C30 scale mood scores were significantly higher （P＜0.05 or P＜0.01）. The total effective rate of MoCA was 58.33%. The difference in zALFF values of the left temporal pole middle temporal gyrus before and after treatment was negatively correlated with the MoCA total score （r= -0.499， P = 0.015）， as well as the difference in abstract function （r = -0.498， P = 0.016）. ConclusionThe acupuncture method of regulating qi and blood， nourishing mind and benefiting intelligence can improve the cognitive function of breast cancer patients with CRCI， and its mechanism may be related to improving the functional activities of hippocampus， amygdala and temporal lobe， as well as the functional connections of left temporal pole-temporal middle gyrus and right posterior cerebellar lobe.

【Objective】 To study the changes in erythrocyte osmotic fragility(EOF) in patients with hypercythemia, polycythemia and anemia under a high altitude environment. 【Methods】 A total of 174 outpatients, inpatients and people undergoing physical examination in Tibet Autonomous Region People′s Hospital in October 2020 were enrolled and divided into four groups according to hemoglobin levels: the polycythemia group(n=42), the physiologic increase group(n=48), the anemia group(n=29) and the healthy control group(n=55). They were compared with 67 anemia patients and 67 healthy people in the laboratory of Peking Union Medical College Hospital in the same period as the plain control group. The classic EOF test method was used to compare the results of each group′s EOF. The concentrations of NaCl solution for starting hemolysis (STH) and NaCl solution for complete hemolysis (CTH) were included, and the data were statistically analyzed by SPSS software. 【Results】 There was a significant difference in CTH between Zang and Han healthy people (P<0.05). STH in high altitude polycythemia group(0.52) was higher than that in high altitude healthy control group(0.48) (P<0.001). Compared with plain, the median CTH of plateau anemia group(0.36) and plateau health control group(0.36) was significantly higher than that of plain anemia group(0.28) and plain control group(0.28) (P<0.001). Multivariate logistic regression analysis showed that plateau region, female polycythemia and anemia were risk factors for STH elevation. 【Conclusion】 This study finds that the EOF increases in the plateau population and patients with polycythemia, which provides reference for studying red blood cell disorders and blood transfusion strategy in the plateau region.
