Differential metabolite analysis of the pharmacodynamic differences between different ratios of Dahuang ()-Taoren () herb pair.

OBJECTIVE: To explore the material basis of the difference of efficacy of Dahuang (Radix Et Rhizoma Rhei Palmati)-Taoren (Semen Persicae) (DT) drugs with different proportions. METHODS: Samples of different ratios of Dahuang (Radix et Rhizoma Rhei Palnati, DH) to Taoren (Semen Persicae, TR) (Group A 1:1, B 2:3, C 3:2) were analyzed based on gas chromatography time-of-flight mass spectrometry untargeted metabolomics technique. RESULTS: A total of 240 primary metabolites were detected. Forty-one differential metabolites involved nine differential metabolic pathways, of which four were closely related to the efficacy of DT in the treatment of heat and blood stasis syndrome. These pathways included the biosynthesis of amino acid (phenylalanine tyrosine and tryptophan), flavonoids, unsaturated fatty acids, and the glycolysis/glycogenesis pathway. CONCLUSION: There are significant differences in the efficacy of different ratios of DT drugs, and their optimal ratio for the treatment of heat and blood stasis syndrome should be 1:1.

Application of digital technology in the reconstruction of orbital fractures: research progress / 中华创伤杂志

Orbital fracture often leads to facial collapse, diplopia, enophthalmos, and even blindness. Traditional surgery relies on the experiences of physicians to achieve fracture reduction and orbital wall reconstruction, but the repair effect is not satisfactory. In recent years, with the development of digital technology, technologies such as computer-assisted surgery, 3D printing, surgical navigation systems, and intraoperative CT imaging have become increasingly widespread in the field of orbital reconstruction. Such techniques can avoid dependence on physicians′ experiences and make it easy for estimating and positioning the implantation sites, which subsequently contributes to better surgery efficiency and precise reconstruction of the orbit, improving aesthetics and visual function of patients. To this end, the authors reviewed the recent progress in application of digital technology for orbital fracture reconstruction, so as to provide reference and theoretical basis for clinical practice.

Seasonal Prediction of Omicron Pandemic

The ongoing coronavirus disease 2019 (COVID-19) pandemic has pushed the world in the face of another huge outbreak. In order to have a better understanding on the fast transmission of Omicron variant, we made seasonal predictions on the development of Omicron pandemic globally, as well as 11 key countries. The results demonstrated that the pandemic has an exponential-like growth rate at the initial stage of the outbreak, and will have small resurgences around April and June in north hemisphere countries and south hemisphere countries, respectively.

Efficacy of navigation-assisted cosmetic incision for reduction and internal fixation in treating unilateral type B zygomatic fracture / 中华创伤杂志

Objective:To analyze the clinical effect of navigation-assisted cosmetic incision for reduction and internal fixation in treating unilateral B-type zygomatic fracture.Methods:A retrospective cohort study was performed on clinical data of 35 patients with unilateral type B zygomatic fracture treated from January 2018 to December 2019 in First Affiliated Hospital of Fujian Medical University. There were 20 males and 15 females at age range of 5-62 years [(38.7±11.3)years]. Navigation-assisted cosmetic incision for reduction and internal fixation was performed for 17 patients (navigation group), and empirical incision to reduction and internal fixation was performed for 18 patients (convention group). The length of bony zygomatic process (zygomatic process) and width of zygomatic temporal point (frontal width) of the bilateral zygomatic bone were measured on the horizontal axis of CT at 1 week after operation. The absolute values of the difference of bony zygomatic process degree and frontal bony width between affected side and the healthy side were compared between the two groups. The patients′ satisfaction and occurrence of complications such as lower eyelid ectropion, incision infection and facial nerve injury were compared between the two groups at half a year after operation.Results:All patients were followed up for 6-24 months [(9.3±1.2)months]. The absolute difference of bony zygomatic process was 0.60(0.25, 0.85) mm in navigation group, and was 0.75 (0.20, 1.98)mm in convention group ( P>0.05). The absolute difference of frontal bony width was (0.37±0.11)mm in navigation group, and was (2.47±0.63)mm in convention group ( P<0.01). Satisfaction rates by both objective evaluation and subjective evaluation in navigation group were better than that in convention group at half a year after operation (both P<0.05). Navigation group showed lower eyelid ectropion in 1 patient and incision infection in 1 patient. Convention group showed facial nerve injury in 1 patient and incision infection in 2 patients. There was no significant difference in the incidence of complications between navigation group [12%(2/17)] and conventional group [17%(3/18)] ( P>0.05). Conclusion:For unilateral type B zygomatic fracture, navigation-assisted cosmetic incision for reduction and internal fixation can more accurately restore the frontal width, and improve satisfaction rate as compared with empirical reduction and internal fixation.

Application of Chinese medicine in enhanced recovery around surgery in perioperative period of laparoscopic anterior resection for rectal cancer patients / 国际中医中药杂志

Objective:To explore the application of enhanced recovery around surgery (CMERAS) by integrated Traditional Chinese Medicine & western medicine in perioperative period of laparoscopic anterior resection for rectal cancer patients.Methods:100 patients with rectal cancer who were treated by laparoscopic anterior resection in Shuguang Hospital from July 2017 to July 2019 were divided into two groups with random number table method, 50 patients in each group. The control group received enhanced recovery after surgery (ERAS) perioperative treatment and the observation group received CMERAS perioperative treatment. Both groups were treated for 7 days. The degree of intestinal cleansing during the operation and postoperative rehabilitation quality were observed of the two groups, including the time of first exhaust, hospitalization time and the incidence of complications. Serum CRP level was detected by immunoturbidimetry, serum IL-6 level was detected by chemiluminescence immunoassay and peripheral blood CD4, CD8 and CD4/CD8 were detected by flow cytometry. Adverse reactions were recorded for the two groups.Results:There was no significant difference in the degree of intestinal cleansing between the two groups during operation ( Z=-1.140, P=0.254). The first postoperative exhaust time in the observation group (29.7 ± 4.6 h vs. 36.1 ± 3.8 h, t=7.590) was earlier than that of the control group, the hospitalization time (4.2 ± 0.5 d vs. 4.7 ± 0.6 d, t=4.379) was less than that of the control group, and the incidence of complications [8.0% (4/50) vs. 30.0% (15/50), χ2=6.498] was lower than that of the control group ( P<0.01). On the third day after the operation, serum CRP (11.84 ± 4.69 mg/L vs. 23.63 ± 5.04 mg/L, t=12.106) and IL-6 (34.31 ± 5.93 ng/L vs. 44.39 ± 8.81 ng/L, t=6.714) in the observation group were lower than those in the control group ( P<0.05). CD4 levels [(37.74 ± 7.28)% vs. (33.55 ± 5.07)%, t=-3.344], CD4/CD8 ratio (1.36 ± 0.27 vs. 1.13 ± 0.22, t=-4.920) were higher than those in the control group ( P<0.01), and CD8 levels [(28.04 ± 4.68)% vs. (30.22 ± 4.04)%, t=2.487] was lower than that of the control group ( P<0.05). There were no adverse reactions in two groups during the treatment. Conclusion:CMERAS could promote the perioperative recovery of patients with rectal cancer if treated with laparoscopic anterior resection and fewer complications would occur.

Projecting the second outbreaks for global COVID-19 pandemic

COVID-19 is now in an epidemic phase, with a second outbreak likely to appear at any time. The intensity and timing of a second outbreak is a common concern worldwide. In this study, we made scenario projections of the potential second outbreak of COVID-19 using a statistical-epidemiology model, which considers both the impact of seasonal changes in meteorological elements and human social behaviors such as protests and city unblocking. Recent street protests in the United States and other countries are identified as a hidden trigger and amplifier of the second outbreak. The scale and intensity of subsequent COVID-19 outbreaks in the U.S. cities where the epidemic is under initial control are projected to be much greater than those of the first outbreak. For countries without reported protests, lifting the COVID-19 related restrictions prematurely would accelerate the spread of the disease and place mounting pressure on the local medical system that is already overloaded. We anticipate these projections will support public health planning and policymaking by governments and international organizations.

Proteomics Uncovers Immunosuppression in COVID-19 Patients with Long Disease Course

Little is known regarding why a subset of COVID-19 patients exhibited prolonged positivity of SARS-CoV-2 infection. Here, we present a longitudinal sera proteomic resource for 37 COVID-19 patients over nine weeks, in which 2700 proteins were quantified with high quality. Remarkably, we found that during the first three weeks since disease onset, while clinical symptoms and outcome were indistinguishable, patients with prolonged disease course displayed characteristic immunological responses including enhanced Natural Killer (NK) cell-mediated innate immunity and regulatory T cell-mediated immunosuppression. We further showed that it is possible to predict the length of disease course using machine learning based on blood protein levels during the first three weeks. Validation in an independent cohort achieved an accuracy of 82%. In summary, this study presents a rich serum proteomic resource to understand host responses in COVID-19 patients and identifies characteristic Treg-mediated immunosuppression in LC patients, nominating new therapeutic target and diagnosis strategy.

Environmental indicator for effective control of COVID-19 spreading

Recently, a novel coronavirus (COVID-19) has caused viral pneumonia worldwide, spreading to more than 200 countries, posing a major threat to international health. To prevent the spread of COVID-19, in this study, we report that the city lockdown measure was an effective way to reduce the number of new cases, and the nitrogen dioxide (NO2) concentration can be adopted as an environmental lockdown indicator. In China, after strict city lockdown, the average NO2 concentration decreased 55.7% (95% confidence interval (CI): 51.5-59.6%) and the total number of newly confirmed cases decreased significantly. Our results also indicate that the global airborne NO2 concentration steeply decreased over the vast majority of COVID-19-hit areas based on satellite measurements. We found that the total number of newly confirmed cases reached an inflection point about two weeks after the lockdown. The total number of newly confirmed cases can be reduced by about 50% within 30 days of the lockdown. The stricter lockdown will help newly confirmed cases to decline earlier and more rapidly. Italy, Germany and France are good examples. Our results suggest that NO2 satellite measurement can help decision makers effectively monitor control regulations to reduce the spread of COVID-19.

Long period dynamics of viral load and antibodies for SARS-CoV-2 infection: an observational cohort study

OBJECTIVETo investigate the dynamics of viral RNA, IgM, and IgG and their relationships in patients with SARS-CoV-2 pneumonia over an 8-week period. DESIGNRetrospective, observational case series. SETTINGWenzhou Sixth Peoples Hospital PARTICIPANTSThirty-three patients with laboratory confirmed SARS-CoV-2 pneumonia admitted to hospital. Data were collected from January 27 to April 10, 2020. MAIN OUTCOME MEASURESThroat swabs, sputum, stool, and blood samples were collected, and viral load was measured by reverse transcription PCR (RT-PCR). Specific IgM and IgG against spike protein (S), spike protein receptor binding domain (RBD), and nucleocapsid (N) were analyzed. RESULTSAt the early stages of symptom onset, SARS-CoV-2 viral load is higher in throat swabs and sputum, but lower in stool. The median (IQR) time of undetectable viral RNA in throat swab, sputum, and stool was 18.5 (13.25-22) days, 22 (18.5-27.5) days, and 17 (11.5-32) days, respectively. In sputum, 17 patients (51.5%) had undetectable viral RNA within 22 days (short persistence), and 16 (48.5%) had persistent viral RNA more than 22 days (long persistence). Three patients (9.1%) had a detectable relapse of viral RNA in sputum within two weeks of their discharge from the hospital. One patient had persistent viral RNA for 59 days or longer. The median (IQR) seroconversion time of anti-S IgM, anti-RBD IgM, and anti-N IgM was 10.5 (7.75-15.5) days, 14 (9-24) days, and 10 (7-14) days, respectively. The median (IQR) seroconversion time of anti-S IgG, anti-RBD IgG, and anti-N IgG was 10 (7.25-16.5) days, 13 (9-17) days, and 10 (7-14) days, respectively. By week 8 after symptom onset, IgM were negative in many of the previously positive patients, and IgG levels remained less than 50% of the peak levels in more than 20% of the patients. In about 40% of the patients, anti-RBD IgG levels were 4-times higher in convalescence than in acute phase. SARS-CoV-2 RNA coexisted with antibodies for more than 50 days. Anti-RBD IgM and IgG levels, including anti-RBD IgM levels at presentation and peak time, were significantly higher in viral RNA short persistence patients than in long persistence patients. CONCLUSIONThis study adds important new information about the features of viral load and antibody dynamics of SARS-CoV-2. It is clear from these results that the viral RNA persists in sputum and stool specimens for a relatively long time in many patients. Anti-RBD may also serve as a potential protective antibody against SARS-CoV-2 infection, as viral persistence appears to be related to anti-RBD levels. Earlier treatment intervention also appears to be a factor in viral persistence. WHAT IS ALREADY KNOWN ON THIS TOPICThere are several reports about the serum antibodies against SARS-CoV-2. However, most of them evaluate diagnostic accuracy. Only two articles report dynamics of SARS-CoV-2 viral RNA and antibodies with serial samples, but the observation periods are within 30 days. None of the studies investigate the profiles of SARS-CoV-2 viral load and antibodies in a long period. Three reports investigate profiles in respiratory samples, but there are no reports on the dynamics of the viral load in stool samples. WHAT THIS STUDY ADDSIn both sputum and stool, SARS-CoV-2 RNA persists for a long time. The anti-RBD antibodies may involve in the clearance of SARS-CoV-2 infection. After eight weeks from symptom onset, IgM were negative in many of the previously positive patients, and IgG levels remained less than 50% of the peak levels in more than 20% of the patients. In about 40% of the patients, anti-RBD IgG levels increased 4-time higher in convalescence than in acute phase. Long persistence of SARS-CoV-2 viral RNA in sputum and stool presents challenges for management of the infection. The IgM/IgG comb test is better than single IgM test as a supplement diagnostic tool. Anti-RBD may be a protective antibody, and is valuable for development of vaccines.

The relationship between physical activity and incident hypertension in rural Chinese / 中华预防医学杂志

Objective@#To investigate the relationship between physical activity (PA) and the risk of incident hypertension among population in rural areas of China.@*Methods@#The Community Intervention of Metabolic Syndrome in China & Chinese Family Health Study (CIMIC) was conducted in 2007-2008. Data on PA, smoking, drinking, blood pressure and other variables were obtained at baseline. Then the follow-up study of incident hypertension was performed during 2012-2015. A total of 41 457 participants aged ≥18 years and free from hypertension at baseline were included in the final analyses. PA was calculated as metabolic equivalent (MET) for each participant. Cox proportional hazard models were used to explore the relationship of PA with incident hypertension according to the quartiles of PA.@*Results@#A total of 6 780 participants developed hypertension during an average follow up of 5.8 years. The annual incidence of hypertension was 2.80%. Compared to participants in the first quartile of PA, HR (95%CI) of incident hypertension decreased with the level of PA of 0.92 (0.86, 0.99), 0.72 (0.67, 0.77) and 0.70 (0.65, 0.75) for the 2nd, 3rd and 4th quartile, respectively (Ptrend<0.001). In subgroup analyses, compared to the first quartile, hazards of hypertension among normotensive participants (systolic blood pressure less than 120 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure less than 80 mm Hg) in the 2nd, 3rd and 4th quartile were 0.82 (0.70, 0.95), 0.73 (0.63, 0.85) and 0.78 (0.67, 0.90), respectively (Ptrend=0.002). Among participants with prehypertension (systolic blood pressure from 120 to 139 mmHg and/or diastolic blood pressure from 80 to 89 mmHg), similar trend for the relationship of PA and incident hypertension was also found with HR (95%CI) of 0.94 (0.87, 1.01), 0.71 (0.65, 0.77) and 0.66 (0.61, 0.71) for the 2nd, 3rd and 4th quartile, respectively (Ptrend<0.001).@*Conclusion@#There was linear trend association between PA and incident hypertension. Increased PA in daily life may be a protective factor against hypertension.

Construction of death early-warning model for patients with septic myocardial depression: a retrospective analysis of 129 patients / 中华危重病急救医学

Objective To explore the death risk factors of septic myocardial depression (SMD) and their predictive effect, and to set up a death early-warning model. Methods A retrospective analysis was conducted. The patients with SMD admitted to emergency department and rescue room of Beilun Branch of the First Affiliated Hospital of Zhejiang University Medical College from January 2015 to November 2017 were enrolled. The patients were divided into survival group and non-survival group according to 28-day outcome, and the gender, age, and the initial examination parameters [white blood cell (WBC) count, neutrophil (Neut) count, activated partial thromboplastin time (APTT), procalcitonin (PCT), D-dimer, C-reactive protein (CRP), cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left atrium diameter (LAD)] of both groups were compared. Binary logistic regression analysis was conducted on the factors with statistically significant difference analyzed in univariate analysis, and death early-warning model was set up subsequently. For parameters in early-warning model after variable screening, receiver operating characteristic curve (ROC) was applied to evaluate the predictive effect of death. Results A total of 129 patients were enrolled, 34 patients died within 28 days with the mortality of 26.4%. Univariate analysis showed that the PCT, cTnI and NT-proBNP in non-survival group were significantly higher than those of the survival group. However, there was no statistical difference in gender, age, WBC, Neut, APTT, D-dimer, CRP, LVEF, LVEDD or LAD between the two groups. Logistic stepwise regression analysis showed that PCT and cTnI were the independent factors influencing the death of patients with SMD [PCT: odds ratio (OR) =1.495, 95% confidence interval (95%CI) = 1.192-1.876, P = 0.001; cTnI: OR = 11.154, 95%CI = 5.709-17.264, P = 0.004], and the death early-warning model was logP =-3.737+0.402×PCT+2.412×cTnI. According to the statistics of Homser-Lemeshow, the effect of this model was good (χ2= 6.258, P = 0.617). The analysis of ROC displayed that the area under ROC curve (AUC) of the combination of PCT and cTnI for predicting the prognosis of SMD patients was 0.851, and it was significantly higher than that of PCT and cTnI alone (0.738 and 0.719, respectively, both P < 0.05). When the combination of PCT and cTnI was 0.26, the sensitivity was 79.97%, the specificity was 87.01%, the positive predictive value was 71.3%, and the negative predictive value was 91.7%. Conclusions PCT and cTnI are independent factors influencing the death of SMD patients. The combination of PCT and cTnI has predictive value for the prognosis of SMD patients. The death early-warning model of SMD patients can be used to predict the prognosis of SMD patients.

Objective To investigate the expression of serum 25(OH)D,vitamin D receptor (VDR)and vitamin D1-α hydroxylase (CYP27B1) in intestinal mucosa tissues of patients with inflammatory bowel disease (IBD).Methods From January 1st to December 31st in 2014,105 patients with IBD were enrolled,among them there were 49 cases of ulcerative colitis (UC) and 56 cases of Crohn's disease (CD);there were 20 cases in remission,26 cases in mild active phase,37 cases in moderate active phase and 22 cases in severe active phase;and 50 cases with lesions located in the left colon and 55 cases with lesions located in the right colon.At the same period,45 healthy individuals were also recruited as controls,whom were suspected as IBD but at last proved healthy.The lactulose and mannitol absorption ratio (LMR),serum endotoxin,tumor necrosis factor-α (TNF-α) and 25(OH)D levels,and the expressions of VDR and CYP27B1 in the intestinal mucosa tissues were detected in all the subjects.T test,one-way analysis of variance and chi square test were used for statistical analysis.Results The LMR,endotoxin and TNF-α levels of UC group were (63.2 ± 13.9)％,(118.9 ± 19.7) EU/mL,and (109.6 ± 18.4) ng/L,respectively,which were higher than those of the healthy control group ((3.3 ± 1.2)％,(34.2 ±5.6) EU/mL,and (0.6±0.3) ng/L);the level of 25 (OH)D was (36.6± 9.7) nmol/L,which was lower than that of healthy control group ((49.6± 10.9) nmol/L),and all the differences were statistically significant (t =28.796,29.284,27.817 and 6.118,all P＜0.05).LMR,endotoxin and TNF-α levels of CD group were (52.9±11.3)％,(96.4±10.6) EU/mL and (83.0±16.1) ng/L,respectively,which were higher than those of the healthy control group,25(OH)D level was (44.4±9.4) nmol/L,which was lower than that of healthy control group,and all the differences were statistically significant (t=34.555,39.716,34.293 and 0.012,all P＜0.05).The differences in LMR,endotoxin,TNF-α and 25 (OH)D levels among healthy control group,remission group,mild active group,moderate active group and severe active group were statistically significant (F=286.731,385.690,657.830 and 18.932,all P＜0.01) which was dependent on the disease activity.Compared with those of the healthy controls,the levels of LMR,endotoxin and TNF-α of the left colon group and the right colon group increased,and 25(OH)D levels decreased.The high expression rates of VDR in UC group and CD group were 36.7％ (18/49) and 55.4％ (31/ 56),respectively,which were both lower than that of healthy control group (80.0％ (36/45)),and the differences were statistically significant (x2 =38.574 and 13.837,both P＜0.05).The high expression rates of CYP27B1 of UC group and CD group were 26.5％ (13/49) and 35.7％ (20/56),respectively,which were both higher than that of healthy control group (22.2％ (10/45)),and the differences were statistically significant (x2=6.499 and 4.430,both P＜0.05).The differences in the high expression rates of VDR and CYP27B1 among healthy control group,remission group,mild active group,moderate active group and severe active group were statistically significant (F=33.470 and 27.142,both P＜0.01),which was dependent on the disease activity.Compared with that of the healthy control group,the high expression rates of VDR of the left colon group and the right colon group decreased,and the high expression rates of CYP27B1 increased.Conclusion There is vitamin D metabolic imbalance in IBD patients,as well as low serum 25(OH)D level,low rate of high VDR expression in colonic mucosa tissues and high rate of high CYP27B1.

Analysis on health risk behaviors and their influencing factors of 404 undergraduates / 医学研究生学报

Objective The health risk behaviors of undergraduates exist universally, which can induce other social problems. The aim of this study was to describe the present situation and analyze the influencing factors of health risk behaviors of 404 undergradu-ates. Methods Adolescent Health Related Behaviors Questionnaires were conducted in 404 undergraduates chosen from a University in Nantong by stratified cluster sampling method.Logistic regression and multiplicative interactive effects were adopted to analyze the influ-encing factors. Results Health risk behaviors were common among college students.In the past 30 days, 33.4%of students had rule-breaking behaviors in bicycle riding and 45.3%had rule breaking behaviors in walking.In the past 12 months, 2.7%of students had in-tentionally hurt themselves, 2.5%had suicidal inclination, 19.8%had smoking history, 69.3%had drinking history, 7.4%participa-ted in the gambling, 7.7%and 11.9%played video games and surfed online over 4 hours everyday, respectively, and 4.5%of students have had sex.In the past 30 days, 94.3% of students lost their weight through the unhealthy way, and 37.8%of students participated physi-cal exercise over 60 minutes for at least 3 days in the past 7 days.Lo-gistic regression indicated that male, higher grade and higher education level of the student′s mother were the risk factors of some health risk behaviors.Interactive effect was not found between the different influencing factors. Conclusion Health risk behaviors exist widely a-mong college students and more attention should be paid to risk behaviors of college students.Health behaviors should be trained among adolescents to improve their overall health level.

Clinical efficacy of medicinal treatment in 15 children with Dent disease / 中华实用儿科临床杂志

Objective To investigate the drug effect of children with Dent disease who received therapy of po-tassium citrate and thiazide diuretics and angiotensin -converting enzyme inhibitors(ACEI),and to provide the refe-rence for the clinical treatment.Methods Dent disease patient who were followed -up in Bayi Children′s Hospital Af-filiated to Beijing Military Region General Hospital during the period of July 2006 and March 201 4 were selected.The patients were administered a therapy of potassium citrate associated with thiazide diuretics and ACEI according to the level of proteinuria and calciuria and serum potassium.The underlying changes before and after the treatment were com-pared and analyzed.Results In 1 5 children with Dent disease,they were all male cases,onset age ranged from 3 months to 1 1 years old[(2.62 ±3.1 1 )years old],and the disease duration ranged from 0.50 to 9.50 years old [(2.81 ±2.34)years].The patients were followed up for 0.50 to 7.50 years[(3.61 ±2.62)years].There was a sig-nificantly statistical difference in calcium/creatinine and daily Ca -creat ratio in contrast to before treatment[(0.41 ± 0.1 9)mg/mg vs(0.26 ±0.1 2)mg/mg,t =2.603,P =0.021 ;(6.76 ±2.0)mg/kg vs (4.34 ±1 .97)mg/kg,t =5.265,P =0.000],there was no significantly statistical difference in 24 -hour urinary protein quantity in contrast to before treatment[(0.96 ±0.62)g/24 h vs (0.87 ±0.44)g/24 h,t =1 .01 6,P =0.327].One case with kidney stone and 5 cases with nephrocalcinosis had a negative result of renal ultrasound after treatment.Conclusions Treatment of potassium citrate combination with thiazide diuretics and ACEI can significantly decrease urinary calcium excretion, make a disappearance of kidney stone and nephrocalcinosi,and it may have a role in protecting renal function.Treat-ment of benazepril can not significantly decrease the proteinuria and has no substantial improvement in low molecular weight protein urine.
