Objective To observe the efficacy of self-made Wenshen Jianpi Formula in the treatment of polycystic ovary syndrome(PCOS)with deficiency of spleen and kidney type,and to explore its mechanism of regulating glucose-lipid metabolism and intestinal flora.Methods A total of 105 PCOS patients with deficiency of spleen and kidney type who attended the clinic at Kunshan Hospital of Chinese Medicine from October 2020 to October 2023 were selected as the study object.According to the treatment methods,the patients were divided into the observation group(53 cases)and the control group(52 cases).The control group was treated with metformin and ethinylestradiol and cyproterone,while the observation group was treated with self-made Wenshen Jianpi Formula on the basis of treatment for the control group,and the course of treatment lasted three months.The changes of traditional Chinese medicine(TCM)syndrome scores,number of follicles,ovarian volume,glucose-lipid metabolism indicators and intestinal flora in the two groups before and after treatment were observed.After treatment,the clinical efficacy and the total incidence of adverse reactions of the patients in the two groups were compared.Results(1)After three months of treatment,the total effective rate of the observation group was 96.23%(51/53),while that of the control group was 76.92%(40/52),and the intergroup comparison(by chi-square test)showed that the clinical efficacy of the observation group was significantly superior to that of the control group(P＜0.01).(2)After treatment,the scores of TCM symptoms such as soreness and weakness in the waist and knee,physical intolerance of cold,vertigo and dizziness,lassitude and weakness in the two groups were decreased when compared with those before treatment(P＜0.05),and the decrease of the scores in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the number of follicles in the two groups was reduced(P＜0.05)and the volume of the left and right ovaries were reduced when compared with those before treatment(P＜0.05),and the reduction of follicles number as well as the bilateral ovarian volume in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the levels of total cholesterol(TC),triglycerides(TG),fasting plasma glucose(FPG),2-hour postprandial glucose(2hPG),and glycosylated hemoglobin(HbA1c)in the two groups were decreased when compared with those before treatment(P＜0.05),and the decrease of the above glucose-lipid metabolism indicators in the observation group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the levels of Bifidobacteria and Lactobacilli in both groups were higher(P＜0.05)and the levels of Enterococci and Enterobacteria were lower than those before treatment(P＜0.05),and the observation group had higher levels of Bifidobacteria and Lactobacilli and lower levels of Enterococci and Enterobacteria than the control group after treatment,the differences being statistically significant(P＜0.01).(6)The total incidence of adverse reactions in the observation group was 5.66%(3/53)and that in the control group was 7.69%(4/52),and the intergroup comparison showed that the difference was not statistically significant(P＞0.05).Conclusion Self-made Wenshen Jianpi Formula can significantly enhance the clinical efficacy of PCOS patients with deficiency of spleen and kidney type,reduce the volume of ovaries,decrease the number of follicles,and regulate the imbalance of glucose-lipid metabolism and gut microflora homeostasis effectively,without serious adverse reactions,which is safe and effective.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.

Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

Environmental exposure to heavy metals has been linked to a wide range of human health hazards. We detected the levels of 15 metals in urine samples from 500 representative sub-samples in an ongoing occupational cohort study (Jinchang Cohort) to directly evaluate metal exposure levels. Fifteen metals, namely As, Ba, Be, Cd, Cs, Cr, Co, Cu, Pb, Mn, Ni, Se, Tl, U, and Zn, were detected by inductively coupled plasma quadruple mass spectrometry. The results showed that median creatinine adjustment and geometric mean urinary metal levels were higher in the heavy metal-exposed group, except Se and Zn, than other reported general or occupational populations. Further studies should address the effects of heavy metals on human health.

Background:Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course,and available treatments for delaying the progression to end-stage renal disease are limited.This study aimed to assess the efficacy and safety of the traditional Chinese medicine,Niaoduqing particles,for delaying renal dysfunction in patients with stage 3b-4 CKD.Methods:The present study was a prospective,randomized,double-blind,placebo-controlled,multicenter clinical trial.From May 2013 to December 2013,300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml,min-1· 1.73 m-2,aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces.Patients were randomized in a 1∶1 ratio to either a test group,which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks,or a control group,which was administered a placebo using the same methods.The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment.The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test.The present study reported results based on an intention-to-treat (ITT) analysis.Results:A total of 292 participants underwent the ITT analysis.At 24 weeks,the median (interquartile range) change in Scr was 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the test and control groups,respectively (Z =2.642,P =0.008),and the median change in eGFR was-0.2 (-4.3-2.7) and-2.2 (-5.7-0.8) ml·min-1.1.73 m-2,respectively (Z =-2.408,P =0.016).There were no significant differences in adverse events between the groups.Conclusions:Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD.This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

The prevalence of metabolic syndrome (MS) was investigated in Chinese nickel-exposed workers. A total of 35 104 subjects were enrolled in this study. The age-adjusted prevalence of MS, BMI⋝25, diabetes, hypertension, and abnormal lipid was 13.9%, 29.5%, 12.8%, 27.5%, and 47.1%, respectively. The prevalence of BMI⋝25, hyperglycemia, and hypertension increased with the age of males and females, and was higher in males than in females (37.1% vs 21.5%, 15.9% vs 12.1%, 35.0% vs 24.3%, 54.3% vs 40.4%).

BACKGROUNDA multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis (PD) solutions. Some researchers believe that 6 L/d is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution (Changfu) and its difference between 6 L and 8 L dosage.

METHODSAdult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices.

RESULTSChanges of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate (Ccr). Normalized protein catabolic rate (nPCR) from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume (nUF) and estimated glomerular filtration rate (eGFR). Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L×1.73 m(-2)×w(-1). More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that.

CONCLUSIONSThe domestic PD solution (Changfu) was proven to be as effective as Baxter dialysis solution. During 48-week period, a dosage of 6 L/d was enough for these patients to reach adequate PD. Clinical study promotes technological optimization, further helps to improve the safety indices of the medical products.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

OBJECTIVETo establish an inductively coupled plasma mass spectrometry(ICP-MS) method for determination of 30 trace elements including As, Ba, Be, Bi, Ni, Cd, Co, Cr, Cs, Cu, Ga, Mn, Pb, Sr, Tl, V, Ge, Mo, Nb, Ti, W, Te, Se, Zr, In, Sb, Hg, Ce, La, and Sm in human blood.

METHODThe blood samples were analyzed by ICP-MS after diluted 1/10 with 0.01% Triton-X-100 and 0.5% nitric acid solution. Y, Rh and Lu were selected as internal standard in order to correct the matrix interference of Cr, As, Se, and Hg by a hex pole-based collision-reaction cell. Other elements were determined with standard method. The limits of detection, precision and accuracy of the method were evaluated. The accuracy was validated by the determination of the whole blood reference material.

RESULTSAll the 30 trace elements have good linearity in their determination range, with the correlation coefficient > 0.9999. The limits of detection of the 30 trace elements were in the range of 1.19 - 2.15 µg/L and the intra-precision and inter-precision (relative standard deviation, RSD) were less than 14.3% (except Hg RSD < 21.2%, and Ni RSD < 15.4%). The spiked recovery for all elements fell within 59.3% - 119.2%. Among the 13 whole blood reference materials, V, Cr, Mn, Co, Ni, Cu, As, Se, Cd, Te, and Pb (1.45, 1.19, 18.40, 0.18, 1.57, 591.00, 2.97, 61.00, 0.35, 1.86, and 9.70 µg/L respectively) fell within the acceptable range and the detection results of Hg (0.59 µg/L) and Mo (1.59 µg/L) were slightly beyond the range.

CONCLUSIONThis method was simple, fast and effective. It can be used to monitor the multi-elementary concentration in human blood.
