ABSTRACT
Objective:To investigate the clinical effect of spousal kidney transplantation , and to explore the significance in today's society.Methods:We retrospectively collected the relevant clinical data from the transplantation department of the first hospital of jilin university, from October 2009 to December 2018. Receptors who accepted spousal, parental and compatriot donor kidney is respectively obtained.Then the postoperative efficacy of the three groups were compared.Results:The graft survival rates of spousal kidney transplantation were 94.1% at 3 years and 83.7% at 5 years, which were not significantly different from other types of living kidney transplantation ( P=0.260). There was no significant difference in creatinine at each time point within 3 years after operation between three groups. At 3 years and 5 years after operation, there was no significant difference in creatinine between spouse group and sibling group.But the creatinine of spouse group was lower compared with parent group ( P=0.014, 0.038). The incidence of rejection within 1 years after spousal renal transplantation was 25%, which was significantly higher than parent group and sibling group ( P=0.029). Age of donor, gender of recipient, D/R BMI and incidence of AR or not in recipient were independent predictors for 1-year creatinine in living kidney transplantation (correlation coefficient: 0.048、-26.03、-15.95、10.23; P=0.003、<0.001、0.021、0.013). Conclusions:Spousal kidney transplantation has same clinical efficacy compared with other types of living kidney transplantation, which can greatly improve the donor kidney resource.So it worth being further promotion, but compared with other types of living kidney transplantation, we should be more alert to the incidence of rejection reaction, so as to obtain better curative effect.
ABSTRACT
Objective To evaluate narrow?band imaging(NBI)for early esophageal cancer and pre?cancerous lesions. Methods A total of 170 patients ( 192 lesions) diagnosed as having superficial esophageal carcinoma and precancerous lesions by endoscopy were retrospectively analyzed. Clinical data of endoscopy, narrow?band imaging (NBI) and iodine chromoscopy were analyzed.Results The detection rates of early esophageal cancer were both 100?? 0% in NBI(13/ 13) and iodine staining (13/ 13), with no statisti?cally significant difference (P>0?? 05).The detection rate of high grade intraepithelial neoplasia in NBI and i?odine staining was 94?? 9% (94/ 99) and 100?? 0% (99/ 99) respectively with no statistically significant differ?ence (P>0?? 05); The detection rate of low grade intraepithelial neoplasia in iodine staining was 100?? 0%(80/ 80), significantly higher than that of NBI 78?? 8% (63/ 80) (P<0?? 01).Conclusion NBI and iodine staining endoscopy show better diagnostic value for early esophageal cancer and similar diagnostic value for high grade intraepithelial neoplasia in precancerous lesions. But for the low grade intraepithelial neoplasia, the diagnostic value of iodine staining endoscopy is better than that of NBI.
ABSTRACT
Objective To evaluate the effectiveness and safety of a transanal drainage tube(TDT) for decompression of acute left-sided obstruction of colorectum.Methods Fifty-seven patients with acute left-sided colorectal obstruction were enrolled in this study from January 2010 to December 2014.The obstruction location, property, success rate of insertion, one-procedure rate and complication rate were analyzed.Results There were 53 cases of primary colorectal cancer,among which lesions were located in the transverse colon in 1 case, in descending colon in 10, in sigmoid colon in 24,and in rectum in 18.There were 4other cases, one sigmoid colonic metastases of pulmonary cancer, 1 adhesive colonic obstruction after ovary surgery, 1 cervical cancer involved with rectum with stricture and obstruction, and 1 descending colonic obstruction caused by Crohn's Disease.TDT was successfully inserted in 55 cases(96.5％) without complications,in which 43 cases of primary colorectal cancer finally underwent surgery.TDT indwelled from 0 to 22days, for an average of (8.7± 4.4)d.Hartmann operation was performed in 9 patients,6 of which underwent sufficient lymphnode dissection.Among the 43 patients, one-stage operation was performed in 34 (79.1％),of which 30 cases underwent sufficient lymph node dissection, without stoma leakage.And the rest of 13 cases refused surgery because of poor prognosis and financial problems.One patient with Crohn's Disease refused surgery after TDT insertion and was discharged after palliation of distention.Conclusion TDT is safe and effective in decompressing acute left-sided benign obstruction with high success rate and low expenditure, and can achieve preoperative colonic lavage in one-stage operation for acute left-sided colorectal malignant obstruction.
ABSTRACT
Objective To explore the clinical significance of dynamic determination of serum procalcitonin(PCT)levels in judgment of infection and prognosis in patients with severe craniocerebral injury.Methods A total of 80 patients with severe craniocerebral injury were selected and they were divided into infection group and non-infection group.Infection group was divided into improved group and non-improved group.Acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and Glasgow coma scale(GCS)score was compared between infection group and non-infection group.The level of serum PCT,white blood cell count(WBC),C-reactive protein(CRP)and interleukin(IL)-6 was compared on the first,third,fifth day of admission in intensive care unit among these groups.Results Infection group in 48 patients,and non-infection group in 32 patients.There was no significant difference in age,sex and GCS score between two groups(P ＞0.05).APACHE Ⅱ score in infection group was higher than that in non-infection group [(21.71 ± 7.13)scores vs.(15.32 ± 6.17)scores],and there was significant difference (P＜ 0.05).The level of serum PCT on the first day of admission in intensive care unit in infection group was higher than that in non-infection group[(2.15 ± 1.79)ng/L vs.(0.56 ± 0.47)ng/L],and there was significant difference(P＜ 0.05).There was no significant difference in WBC,CRP and IL-6 between two groups(P＞0.05).The level of serum PCT,WBC,CRP,IL-6 on the third day of admission in intensive care unit in infection group was higher than that in non-infection group,and there was significant difference(P＜ 0.05).The level of serum PCT on the fifth day of admission in intensive care unit in infection group was higher than that in non-infection group [(3.09 ± 1.98)ng/L vs.(1.06 ± 0.63)ng/L],and there was significant difference (P＜0.05).WBC,CRP,IL-6 on the fifth day of admission in intensive care unit was(15.13 ±6.32)×109/L,(103.56 ±40.62)mg/L,(230.41 ± 121.83)ng/L in improved group(38 cases),and (18.62 ±8.89)× 109/L,(134.38 ± 34.16)mg/L,(268.73 ± 138.12)ng/L in non-improved group(10 cases),and there were significant differences between two groups(P ＜ 0.05).The level of serum PCT on the first,third,fifth day of admission in intensive care unit in improved group was lower than that in non-improved group,and there was significant difference(P ＜ 0.05).Conclusion The alteration of serum PCT level may be used as one of the effective predictors for infection in patients with severe craniocerebral injury and for their prognosis.
ABSTRACT
Objective To explore the diagnostic values of bile cytology obtained in endoscopic retrograde cholangiopancreatography (ERCP) and blood tumor markers for malignant bile duct obstruction.Methods From August 2005 to April 2009, bile cytology and blood tumor markers measurement were performed in 47 cases with bile duct obstruction, in which 39 cases were confirmed to be malignant and 8 were benign. Results Malignant cells were found in bile from 26 of 39 malignant obstruction (66. 7% ), and serum CA19-9 was positive in 28 (71.8%). No malignant cells were detected in bile cytology from 8 cases with benign obstruction (with a specificity of 100% ) and serum CA19-9 was negative in 7 (87.5%). In 26 patients with cholangiocarcinoma, serum CA19-9 was positive in 18 (69. 2% ). For bile cytology and blood tumor markers test, sensitivity of parallel combination was 89. 7%, and the specificity of serial combination was 100. 0%. Conclusion Bile cytology testing during ERCP can provide the pathological evidence for malignant bile duct obstruction. The sensitivity is improved by combination tests of bile cytology and blood tumor markers.

Objective To establish the platelet antigen panel for identifying the specificity of platelet antibodies which cause platelet transfusion refractoriness and neonatal alloimmune thrombocytopenia and provide evidence for clinical therapy and platelet genotyping research.Methods Based on the frequency distribution of human platelet alloantigen (HPA)-1 to HPA-16 gene in China, the frequencies of HPA-1 to HPA-6,HPA-15 alleles in blood group O donors were genotyped by the polymerase chain reaction with sequence-specific primers (PCR-SSP) method, and suitable donors were chosen to establish platelet-specific antigen panel.Using the established platelet-specific antigen panel, the specificity of platelet antibodies caused by alloimmune reaction was identified by using simplified sensitized erythrocyte platelet serology assay (SEPSA).Results Eleven ptatelet donors with blood group O were chosen to establish platelet-specific antigen panel which can identify specificity of HPA-1 to HPA-6, HPA-15 antibodies.One case of HPA-4b (Penb) and two cases of HPA-15a (Govb) platelet specific antibodies were detected in 1 120 samples.Conclusion Identifying the specific platelet antibodies using platelet specific antigen panel has profound significance on increasing the safety and effectiveness of clinical platelet transfusion and prevention of neonatal alloimmune thrombocytopenia.
ABSTRACT
Objective To investigate the genetic polymorphism of the transmembrane region of the MICA locus in Guangdong Han population,and to protract the genetic distance in different populations.Methods DNA samples from 106 unrelated Han individuals were genotyped by PCR to analyze the frequencies of MICA alleles.The genetic distance was estimated and the phylogenetic tree was protracted by DISPAN Software.Results In total,5 alleles of MICA-TM were observed,they were A4,A5,A5.1,A6 and A9.MICA-TM A5 was the dominant allele(0.2877),whereas A4 was the least popular one(0.1321).From genetic distance and phylogenetic tree we made,the preliminary finding is that Chinese Hans may have migrated from southwest China to northern and southern China.Conclusion MICA-TM locus has high genetic polymorphism and obvious variance in different populations.Since the genetic distance could be estimated effectively through MICA-TM locus,it could serve as the genetic marker in human migration and evolution research.
ABSTRACT
AIM: To explore the effects of uremic serum on proliferation and trans-differentiation of human renal tubular epithelial cells. METHODS: Human renal tubular epithelial cell line (HK-2) was cultured in RPMI-1640 medium. The proliferation effects of uremic serum at different concentrations were evaluated by methylene blue assay (MTT method) and flow cytometry. The positive cells percentage of ?-smooth muscle actin(?-SMA)in different concentration uremic serum medium was also measured by flow cytometry in vitro. RESULTS: Absorbance 490 (A 490) was increased in 5%-20% uremic serum groups compared with that in normal controls with the use of MTT. Cells in G 1 phase were decreased, but proliferation index (PI) was increased in 10%-20% uremic serum groups compared with that in normal controls with the use of flow cytometry. No significant difference of cell proliferation index was found among uremic serum groups. The positive percentage of ?-SMA cells was increased significantly in uremic serum groups compared with that in normal controls, and increased in parallel with the increasing of uremic serum concentration. CONCLUSION: Uremic toxin may accelerate renal tubulointerstitial fibrosis through promoting renal tubular epithelial cell proliferation and trans-differentiation in patients with chronic renal failure.
