Two patients with coexistence of thyroid disease and suspected Gitelman's syndrome underwent SLC12A3 gene analysis. The results confirmed that both patients were compound heterozygotes of SLC12A3 gene mutation. Three novel variants of SLC12A3 were found in this study. This report suggests that Gitelman's syndrome may coexist with other disorders associated with hypokalemia, such as Graves' disease.

Background Studies showed that macophenolic acid (MPA)down-regulates and inhibits the expression and secretion of tissue growth factor and inflammatory factor,and further impacts the proliferation and inflammation process.Pterygium is an inflammatory and proliferative lesion.Whether MPA has an inhibitory effect on pterygium is unclear.Objective This study was to investigate the antifibrotic effects of macophenolic acid on pterygium fibroblasts(PFBs) in vitro and discuss its mechanism.Methods Pterygium tissue was obtained from pterygium patient during the surgery.PFBs were cultured using explants and identified with vimentin immunohistochemisty.0,0.125,0.250,0.500,1.000 μmol/L MPA were added into the culture medium,respectively,and the cells were cultured in the medium without MPA as the control group.MTT colorimetry was used to find the optimization effective concentration of MPA and evaluate their inhibitory effect on PFBs,and BrdU fluorescence staining was used to assess the growth statue of PFBs.Expressions of nuclear factor-κB(NF-κB),p65 and inhibitor of NF-κB-α(IκB-α) in the cells were detected by Western blot.Results The cells was spindle in shape 3 days after cultured and showed the vortex and radial arrangement with the positive response to vimentin.With the increase of MPA,the proliferative value of PFBs (A560)showed gradually decline,with a significant difference among the five groups (F =42.874,P＜0.01).In addition,the proliferative value of PFBs (A560) significantly lowed as the prolong of MPA active time(F=26.038,P＜0.01).BrdU fluorescence staining showed a significant decrease of DNA synthesis of PFBs with the elevation of MPA dose among the five groups(F=175.279,P＜0.05),and the A560of PFBs DNA synthesis in different concentrations of MPA groups was lower than that of the control group (all at P＜0.05).No apoptotic and necrotic cell was found after MPA action by DAPI staining.The expression level of p65 in the PFBs was 0.886±0.072 and 1.542±0.124 in the MPA group and the control group,indicating a declined value in the MPA group(P＜0.05).However,the expression value of IκB-α in the cytoplasm PFBs was significantly higher in the MPA group compared with the control group(2.141 ±0.305 vs.1.559±0.267) (P＜0.05).Conclusions MPA has an inhibitory effect on the growth of PFBs,which probably is related to the arresting of NF-κB pathway.

Objective To study the clinicopathologieal features and expression of cyclin D1 and p53 in epithelial ovarian tumors,and to investigate the correlation between pathogenesis of ovarian cancer and epithelial borderline tumors.Methods Fifty four cases of ovarian borderline tumors and 45 cases of ovarian carcinomas from the People's Hospital,Peking University were reviewed retrospectively.The clinical data and pathological findings were analyzed.Immunohistochemical study of cyclin D1 and p53 was performed in all 99 cases.Results(1)In borderline tumors,the age of patients ranged from 14-82 (mean age=42.5)years.International Federation of Gynecology and Obstetrics(FIGO)stage of borderline tumors was stage Ⅰ in 48 cases,stage Ⅱ in 3 cases,and stage Ⅲ in 3 cases.In ovarian carcinomas,the age of patients ranged from 26-80(mean age=53.5)years.FIGO stage of carcinoma was stage Ⅰ in 6 cases, stage Ⅱ in 8 cases,stage Ⅲ in 26 cases,and stage Ⅳ in 5 cases.In follow-up of 54 cases with borderline tumors the 5-year survival rate was 98% and of 45 cases with carcinomas a 5-year survival rate of 51% was noted.(2)In 54 cases of borderline tumors,mucinous types accounted for 56%(30/54)and serous types accounted for 30%(16/54).There were 5 cases with micropapillary pattern,3 cases with peritoneal implants,3 cases with lymph node involvement,6 cases with microinvasion,one case with intraepithelial carcinoma,and one case with mural nodules.In 45 cases of carcinomas,serous carcinoma was the most (49%,22/45).The remainder included 3 cases of mucinous types,8 cases of endometrioid types,6 cases of transitional cell types,3 cases of mixed phenotype and 3 cases of undifferentiated types.(3) Overexpression of cyclin D1 and p53 was observed in 31%(14/45)and 56%(25/45)of ovarian carcinomas, respectively.There was a significant association between p53 overexpression and tumor grade.In the borderline tumor group,69%(37/54)had overexpression of cyelin D1 and 6%(3/54)had overexpression of p53.There were significant differences in expression of cyclin D1 and p53 between conventional serous borderline tumors and high-grade serous carcinomas(cyclin D1:91% vs 26%;p53:0 vs 58%).However, micropapillary serous borderline tumors and low-grade serous carcinomas showed remarkably similar expression of cyelin D1 and p53.Conclusions Epithelial ovarian borderline tumors are distinct from ovarian cancer in clinical progress and prognosis,and histological types.Overexpression of cyclin D1 is common in ovarian borderline tumors and low grade carcinomas.And overexpression of p53 is more common in high grade ovarian carcinomas.Conventional serous borderline tumors are distinct from high-grade serous carcinomas in pathogenesis.Micropapillary serous borderline ovarian tumors may be closely related to low grade serous carcinomas.

Objective To investigate the effects of plaque staining test on periodontal health of middle-aged and elderly patients with dental implants. Methods Ninety patients with dental implants were included in the study and divided into test group (n=45) and control group (n=45) by using random digit table. In the test group, the patients were all instructed with both routine health education and dental plaque dyeing education, while the control group received routine health education only. The plaque index (PLI) and gingival index (GI) were assessed at months 1 and 6 after implant restoration. Results One month after dental implantation, there were no significant differences in PLI and GI between the two groups (P>0.05), while 6 months after the implantation, the differences in PLI and GI between them were significantly different ( P<0 . 01 ) . Conclusion The plaque dyeing technology applied in the oral health education to elderly patients with dental implants can reduce plaque index and gingival index so that their periodontal health is enhanced.

Abstract: Objective　To analyze the etiological characteristics and drug resistance of patients with bloodstream infection (BSI) in the bacterial resistance monitoring network in Hainan Province from 2018 to 2020, so as to provide laboratory data for clinical diagnosis and treatment. Methods　The clinical data of the subjects were collected, and the etiological characteristics of BSI patients and drug resistance of commonly used drugs in clinical treatment were analyzed retrospectively. SPSS 26.0 software was used for statistical analysis. Results　A total of 877 strains were isolated, including Gram-negative bacteria (584 strains, 66.6%), Gram-positive bacteria (239 strains, 27.2%) and fungi (54 strains, 6.2%); male patients (591 cases, 67.4%), female patients (286 cases, 32.6%); inpatients (780 cases, 88.9%), outpatient and emergency patients (97 cases, 11.1%); the main primary diseases of BSI patients were hypertension, cerebral infarction and type 2 diabetes, and the main primary infections were pulmonary infection and urinary system infection. Intensive care unit (25.2%, 221 cases), emergency department (10.9%, 96 cases), oncology department (9.1%, 80 cases), nephrology department (6.8%, 60 cases) and hepatobiliary and pancreatic surgery department (4.3%, 38 cases) had the highest proportion of pathogenic bacteria. Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, coagulase-negative Staphylococcus, Viridans group streptococci and Candida albicans were the most frequently isolated pathogens. The detection rates of carbapenem-resistant Klebsiella pneumoniae, carbapenem-resistant Pseudomonas aeruginosa and carbapenem-resistant Acinetobacter baumannii were 3.4%, 15.2% and 36.4% respectively. The carbapenem-resistant Escherichia coli was not checked out. The detection rates of methicillin resistant Staphylococcus aureus and methicillin resistant coagulase negative Staphylococcus were 18.5% and 79.1% respectively. Conclusions　Gram-negative bacteria are the most common pathogens of BSI, and inpatients are the main source of BSI. Age, underlying diseases and primary infection are the risk factors of BSI. Clinical laboratories should strengthen the etiological monitoring of high-risk patients with BSI, and the resistance analysis of common antibiotics can provide a basis for the rational use of antibiotics in clinical practice.

OBJECTIVETo define cut-off values of plasma amino-terminal pro-B-type natriuretic peptide (NT-ProBNP) for the diagnosis of congenital heart failure (CHF) and evaluate the importance of plasma NT-ProBNP measurement in the assessment of cardiac function prior to heart surgery in infants with congenital heart disease (CHD).

METHODSPlasma levels of NT-proBNP were measured in 120 infants with CHD before heart surgery and in 100 age-matched healthy infants between June 2010 and June 2013. The data were stratified based on the presence or absence of CHF in the whole group of CHD infants and on age (i.e., <1 year and ≥1 year) and time (i.e., before surgery) within the subgroup of CHF infants.

RESULTSOf the 120 infants with CHD, 41 met the criteria for CHF defined in the Ross Classification for Heart Failure in Infants.The cut-off values of plasma NT-ProBNP were ≥498 ng/L for infants of all ages, 557 ng/L for <1 year age group and 452 ng/L for ≥1 year age group, respectively, in the 41 CHF patients. In CHF infants, plasma NT-proBNP was significantly decreased after protecting of cardiac function (P<0.001).

CONCLUSIONSThe cut-off values of plasma NT-ProBNP for CHF differ between infants <1 year and infants ≥1 year. Moreover, plasma NT-ProBNP can be used as an additional parameter in the preoperative assessment of cardiac function in CHD infants.

Objective To evaluate the clinical significance of epithelial cellular adhesion molecule (Ep-CAM)expression in esophageal squamous cell carcinoma(SCC).Methods The Ep-CAM expression was immunohistochemically investigated in 70 normal esophageal mucosas,SCCs and 72 lymph nodes.Results Ep-CAM expression was observed in 94.3% of the tumors,but no expression in the normal mucosa.The Ep- CAM expression was not significantly different between different tumor scales and tumors invading depths,its expression level was relevant with the tumors differentiation and lymph node metastases(P

OBJECTIVETo make a comparison between the single and combined use of Monkshood Root and Peony Root to observe the anti-inflammation effect in the experimental animals.

METHODThe experimental inflammatory models were adopted, i.e. adjuvant-induced polyarthritis carrageenan-induced or formaldehyde-induced rat paw edema, and cotton pellet-induced granuloma formation in rats xylene-induced mouse ear edema, exudation of abdominal blood capillaries of mice, etc.

RESULTThe anti-inflammafion effect of Monkshood Root was weaker than that of Peony Root or Peony Root combined with Monkshood Root. It was found that anti-inflammation effect with the drug-cooperation was enhanced more significantly in the formaldehyde-induced or adjuvant-induceed arthritis models than in the carrageenan-induced rat paw edema and other inflammatory models either in the large dosage of 1:1 proportion or in the small dosage of 1:2 proportion.

CONCLUSIONThe drug-cooperation has a good selective and synergic effect on anti-inflammation.
