Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Objective·To investigate the relation between urinary excretion of protein-bound uremic toxins(PBUTs)and upper urinary tract calculus.Methods·Residents aged 18?80 years in the community of Haitou,Danzhou city in Hainan Province were recruited.Basic information and diet for the last 3 d of the subjects were recorded.Their fasting sera and 24-hour urine samples were collected,and they also underwent ultrasound examination of kidneys and ureters.The subjects with upper urinary calculi detected by ultrasound or a clear history of upper urinary calculi were selected as the calculus group,and the others as the non-calculus group.The biochemical indicators related to the formation of calculus in blood and urine were detected,and the levels of PBUTs,including indoxyl sufate(IS),indole-3-acetic acid(IAA),and p-cresol sulfate(PCS)in blood and urine,as well as oxalic acid and citric acid in urine were detected by high-performance liquid chromatography.The related factors of upper urinary tract calculus formation were analyzed by multivariate Logistic regression.The correlations of urine PBUTs with urine uric acid,oxalic acid,and citric acid were analyzed by Spearman correlation test.Results·A total of 117 participants were screened out with 54 people in the calculus group and 63 people in the non-calculus group.There were no significant differences between the two groups in terms of gender,age,serum indicators,and prevalence of complications such as hypertension,diabetes,and hyperuricemia/gout.The 24-hour urine pH,calcium,uric acid,and chlorine in the calculus group were significantly higher than those in the non-calculus group(all P<0.05),while IS was significantly lower than that in the non-calculus group(P<0.05).Multivariate Logistic regression analysis showed that urinary IS(OR=0.929,95%CI 0.875?0.986,P=0.016)was related to the calculus formation independently,in addition to urinary calcium.The Spearman correlation analysis results showed that the levels of IAA(r=0.420,P=0.000)and PCS(r=0.307,P=0.001)in 24-hour urine were positively correlated with oxalic acid,PCS was positively correlated with uric acid(r=0.297,P=0.002),and IS was positively correlated with citric acid(r=0.289,P=0.002).Conclusion·In the population,a decrease in urinary excretion of IS may be an independent risk factor for the formation of upper urinary tract calculus,and PBUTs levels are correlated with levels of uric acid,oxalic acid,and citric acid.

Background: Prediabetes leads to declines in physical function in older adults, but the impact of prediabetes progression or regression on physical function is unknown. This study assessed this longitudinal association, with physical function objectivelymeasured by grip strength, walking speed, and standing balance, based on the Health and Retirement Study enrolling United States adults aged >50 years. Methods: Participants with prediabetes were followed-up for 4-year to ascertain prediabetes status alteration (maintained, regressed, or progressed), and another 4-year to assess their impacts on physical function. Weak grip strength was defined as <26 kg for men and <16 kg for women, slow walking speed was as <0.8 m/sec, and poor standing balance was as an uncompleted fulltandem standing testing. Logistic and linear regression analyses were performed. Results: Of the included 1,511 participants with prediabetes, 700 maintained as prediabetes, 306 progressed to diabetes, and 505 regressed to normoglycemia over 4 years. Grip strength and walking speed were declined from baseline during the 4-year followup, regardless of prediabetes status alteration. Compared with prediabetes maintenance, prediabetes progression increased the odds of developing weak grip strength by 89% (95% confidence interval [CI], 0.04 to 2.44) and exhibited larger declines in grip strength by 0.85 kg (95% CI, –1.65 to –0.04). However, prediabetes progression was not related to impairments in walking speed or standing balance. Prediabetes regression also did not affect any measures of physical function. Conclusion Prediabetes progression accelerates grip strength decline in aging population, while prediabetes regression may not prevent physical function decline due to aging.

Objective: To compare the prevalence of dental caries and periodontal disease in patients with end-stage renal disease treated with maintenance hemodialysis with that in healthy controls and to investigate the relationship between end-stage renal disease, dental caries and periodontal disease. Methods : A total of 82 maintenance hemodialysis patients who met the inclusion criteria were selected as the case group, and 86 healthy persons who underwent oral examination in the physical examination center were selected as the control group. Dental caries and periodontal conditions were examined in the two groups. The dental caries examination was conducted by determining the number of decayed-missing-filled teeth, which was recorded as recommended by the World Health Organization. The periodontal condition parameters included the plaque index, calculus index, bleeding on probing, periodontal pocket depth and clinical attachment loss. Results: The prevalence of dental caries in the case group and healthy control group was 87.8% and 81.4%, respectively, and there was no statistically significant difference between the two groups (P > 0.05). The periodontal indexes, including the plaque index, calculus index, probe bleeding index, periodontal pocket depth and clinical attachment level, in the case group were significantly higher than those in the control group (P < 0.05), and the prevalence of periodontitis in the case group was significantly higher than that in the control group (97.6% vs 88.4%, P < 0.05). Conclusion The dental caries conditions were comparable between the case group and the control group, but the prevalence and severity of periodontitis were significantly higher in the case group than in the control group.

Objective To observe the effect of ultrasound-guided transversus abdominis plane block combined with diclofenac sodium suppository in anus on postoperative analgesia and early recov-ery after laparoscopic hysterectomy.Methods Sixty-six patients of laparoscopic hysterectomy,aged 40-60 years,were randomly divided into group T and group D,33 cases in each group.Group T used ultrasound-guided bilateral transversus abdominis plane (TAP)block after surgery.Group D used TAP block and diclofenac sodium suppositories in anus.All patients received PCIA.Postoperative 24 h sufentanil dosage out of analgesia pump and the effective press times were recorded.The incidence of dysphoria,nausea and vomit within postoperative 24 h,the time of first out-of-bed activity,the time of first anal exhaust and the time of removing urine tube were measured.The plasma concentra-tion of interleukin-6(IL-6),C reactive protein (CRP)and cortisol (Cor)were recorded at the follow-ing four time points:before anesthesia,just postoperative moment,8 and 12 h after surgery. Results Compared with group T,the sufentanil dosage [(18.6±3.2)μg vs (40.8±5.1)μg]and the effective press times [(9.3±2.2)times vs (20.4±3.5)times]were fewer in group D (P<0.05).The incidence of dysphoria,and nausea and vomit were less in group D compared with group T (P<0.05).The IL-6,CRP and Cor of group D at 12 h were lower than those of group T (P<0.05). But the times of first out-of-bed activity,anal exhaust and removing urine tube in two groups were not significantly different.Conclusion Transversus abdominis plane block combined with diclofenac sodium suppositories in anus can provide safe and effective postoperative analgesia for laparoscopic hysterectomy,and promote the early fast recovery.

Objective To compare the effect of oxycodone,sufentanil and fentanyl on immune function in patients with colon cancer under postoperative analgesia,provide guidance and basis for clinical medication.Methods Ninety patients 49 males and 41 females,aged <65 years,ASA physi-cal status Ⅰ or Ⅱ,were enrolled and randomly divided into 3 groups using a random number table (n=30):oxycodone group (group O),sufentanil group (group SF)and fentanyl group (group F).All patients underwent the same way to maintain anesthesia.The PCIA pump recipe were as follows:group O,oxycodone 2 mg/kg+granisetron 3 mg,added normal saline to 100 ml;group SF,sufen-tanil 0.002 mg/kg+granisetron 3 mg,added normal saline to 100 ml;group F,fentanyl 0.02 mg/kg+granisetron 3 mg,added normal saline to 100 ml;The background volume of PCIA electronic pump was 2 ml/h,the amount of each press was 2 ml,the lock time was 1 5 min,the pump time lasted for 24 h and maintained for 2 days after operation.The percentage of CD4+,CD8+and NK cells in venous blood were recorded at the end of surgery,6 h,12 h,24 h and 48 h after surgery.Results In CD4+,in the time points of 6 h,12 h,24 h after surgery,it was significantly higher in group O than that in groups SF and F (P<0.05);CD8+in group O was higher than that of group F,and CD8+in group F was higher than group SF at the time of 6 h after surgery.The group O was significantly higher than that of the groups SF and F at the times of 12 h,24 h after surgery (P<0.05);In NK cells,at the time points of 12 h,24 h and 48 h after surgery,it was significantly higher in group O than in groups SF and F (P<0.05).Conclusion Three analgesic drugs caused decline in immune function.Sufentanil and fentanyl have the similar effects on immunity,but oxycodone have a relatively small effect on immunity.Oxycodone is a more appropriate analgesic drug for colon cancer under postoperative analgesia.
