ABSTRACT

Objective@#To explore the clinicopathological features and the renal biopsy process of a case of IgG4-related chronic interstitial nephritis with perirenal capsule involved and review associated literature to improve the clinician's understanding for this disease and to perform a better renal biopsy.@*Methods@#The onset, diagnosis and treatment course of the disease were described and associated literature were reviewed to summary the clinicopathologic features and key points in renal biopsy.@*Results@#The data of the patient showed that the urine specific gravity was 1.011, with urine protein ± and urine sugar 3+. The concentration of hemoglobin was 53 g/L, serum creatinine was 1665 μmol/L, and IgG4 was 9.39 g/L. Computed tomography showed that both kidneys enlarged slightly with decreased density and low density shadow around the kidneys. On contrast-enhanced scan, irregular low-density enhancement areas were found in both kidneys, and the edge of the boundary was not clear. For the first renal biopsy, no renal parenchyma was found except mainly hyaline collagen fibrils. At the second time, 3 pieces of tissues were obtained, which showed chronic interstitial glomerulonephritis. The IgG4 positive plasma cells were about 60/HPF and the IgG4+/IgG+cells ratio was more than 40%. The diagnosis of IgG4-related chronic interstitial glomerulonephritis was confirmed. After corticosteroid treatment, the serum creatinine decreased to 502 μmol/L after the patient got rid of dialysis.@*Conclusions@#There are various manifestations of renal damage caused by IgG4-related disease. It is necessary to pay attention to the involvement of the perirenal capsule, and to balance the risk of bleeding and poor sampling in renal biopsy.

ABSTRACT

Objective To explore the correlation between major inflammatory factors and septic shock in intensive care unit (ICU) patients, and to provide a basis for the diagnosis and treatment of septic shock. Methods The patients admitted to ICU of the Third People's Hospital of Datong from March 2017 to August 2018 were selected as the research objects. According to the diagnostic criteria of septic shock, the patients were divided into septic shock group and non-septic group. The basic information and inflammatory factors levels of the two groups, including age, gender, body mass index (BMI), course of disease, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), infection site and pathogenic; and C-reactive protein (CRP), procalcitonin (PCT), neutrophil lymphocyte ratio (NLR), N-terminal pro-B-type natriuretic peptide (NT-proBNP), tumor necrosis factor-α (TNF-α), γ-interferon (IFN-γ), interleukins (IL-1β, IL-2, IL-6, IL-8) at 8 hours after diagnosis, were compared. Logistic regression was used to analyze the influencing factors of septic shock in ICU patients. Results A total of 154 ICU patients were selected, of whom 74 had septic shock. The APACHEⅡ score of septic shock group was significantly higher than that of non-sepsis group (23.42±3.64 vs. 15.67±2.26, P < 0.05). There was no significant difference in other baseline data between the two groups. The levels of CRP, NT-proBNP, TNF-α, IFN-γ, PCT, IL-6, IL-8 in the septic shock group were significantly higher than those in the non-septic group [CRP (mg/L): 164.3±22.6 vs. 52.3±16.2, NT-proBNP (ng/L): 426.3±288.9 vs. 167.3±80.6, TNF-α (ng/L): 193.4±39.3 vs. 88.1±20.3, IFN-γ (ng/L): 133.3±52.0 vs. 97.0±56.1, PCT (ng/L):27.6±10.2 vs. 7.3±4.1, IL-6 (ng/L): 83.0±17.6 vs. 20.9±6.4, IL-8 (ng/L): 445.8±34.0 vs. 84.0±25.7, all P < 0.05]. It was shown by Logistic regression analysis that CRP, NT-proBNP, TNF-α, PCT, IL-6 were independent risk factors for septic shock [CRP: odds ratio (OR) = 1.662, 95% confidence interval (95%CI) = 1.132-2.567; NT-proBNP: OR = 14.688, 95%CI = 3.580-20.238; TNF-α: OR = 1.093, 95%CI = 1.043-1.343; PCT: OR = 6.378, 95%CI = 4.556-12.243; IL-6: OR = 9.641, 95%CI = 2.242-13.786; all P < 0.05]. Conclusion The levels of inflammatory factors CRP, NT-proBNP, TNF-α, PCT and IL-6 were significantly increased, which were important factors for early diagnosis of septic shock.

ABSTRACT

Objective@#To investigate the relationship between expressions of OCT-4, CD117 and clinicopathological features and prognosis of patients with ovarian cancer.@*Methods@#A total of 70 paraffin-embedded tissues of patients with ovarian cancer from January 2010 to February 2016 in Shanxi Provincial Cancer Hospital were collected. The expressions of OCT-4 and CD117 were detected by immunohistochemistry.@*Results@#OCT-4 was mainly expressed in cytoplasm, while CD117 was expressed in cell membrane and cytoplasm. The positive expression rate of OCT-4 was 74.3% (52/70), and the positive expression rate of CD117 was 68.6% (48/70). The positive expression rates of OCT-4 in ovarian cancer tissues with poorly differentiation and high CA125 levels (≥500 U/ml), no peritoneal effusion and sensitive to chemotherapy drugs were 92.1% (35/38), 87.5% (28/32), 88.9% (24/27), and 78.7% (48/61), respectively, which were higher than those in ovarian cancer tissues with well and moderately differentiation, low CA125 levels (<500 U/ml), peritoneal effusion and resistance to chemotherapy drugs, the differences were statistically significant (P values were 0.000, 0.020, 0.047, and 0.043). The positive expression rates of CD117 in ovarian cancer tissues with poorly differentiation and peritoneal effusion were 84.2% (32/38) and 79.1% (34/43), respectively, which were higher than those in ovarian cancer tissues with well and moderately differentiation and no peritoneal effusion, the differences were statistically significant (P values were 0.006 and 0.017). Patients with OCT-4-positive expression, peritoneal effusion, and poorly differentiation had a shorter overall survival time (all P < 0.05). The peritoneal effusion and differentiation were independent prognostic factors in patients with ovarian cancer (both P < 0.05).@*Conclusion@#OCT-4 can be used as an important reference for predicting drug sensitivity and evaluating prognosis in patients with ovarian cancer.

ABSTRACT

Aim To examine the effect of zacopride,a specific inward rectifier potassium channel(IK1)agonist,on L-thyroxine(T4)-induced ventricular remodeling and the underlying mechanism.Methods SD rats were randomly divided as control,L-thyroxine(L-thy,1 mg·kg-1·d-1,ig,10 d)model,L-thy +zacopride(5,15,50 μg·kg-1,respectively,ip),L-thy+zacopride(15 μg·kg-1)+chloroquine(7.5 μg·kg-1,ip)and L-thy+captopril(100 mg·kg-1·d-1,drinking water)groups.Echocardiography and cardiac hypertrophic indexes were measured to confirm the establishment of the ventricular remodeling model.The changes of IK1 and L-calcium current(ICa-L)were detected by whole cell patch clamp technique.The confocal microscopy and fluorescent indicator Fluo-4 were applied to examine the intracellular Ca2+ concentration([Ca2+]i)of isolated adult rat ventricular myocytes.Results L-thyroxine induced left ventricular hypertrophy with increased ratio of heart weight(HW)to body weight(HW·BW-1),ratio of left ventrical weight(LVW)to body weight(LVW·BW-1),left ventricular dimension in diastole(LVIDd),left ventricular dimension in systole(LVIDs),interventricular septum thickness(IVS)and decreased ejection fraction(EF),fractional shortening(FS)(P<0.01).Patch clamp data suggested IK1 was downregulated,while ICa-L was upregulated(P<0.01).In isolated adult cardiomyocytes,L-thyroxine increased the cell area and [Ca2+]i(P<0.01).Zacopride treatment obviously alleviated cardiac remodeling,improved cardiac function,reversed the changes of IK1 and ICa-L,and significantly attenuated intracellular calcium overload(P<0.01).The optimum dose of zacopride in vivo was 15 μg·kg-1 at which the effect was compared favourably with captopril,a classical anti-remodeling agent.Low-dose IK1 atagonist chloroquine could reverse the effect of zacopride(P<0.01).Conclusion Via activating IK1,zacopride could significantly decrease Ca2+ influx and intracellular calcium overload thereby inhibiting L-thyroxine-induced cardiac ventricular remodeling.

ABSTRACT

Objective To screen out probable lynch syndrome (LS) associated endometrial cancer (EC) by investigating the expression of mismatch repair (MMR) protein in EC, and to analyze the disease traits combined with clinicopathologic characteristics. Methods The expressions of MSH2, MSH6, MLH1 and PMS2 were detected by using immunohistochemistry (IHC) in 443 EC patients. Results In 443 EC patients, 328 cases (74%) with all MMR proteins expression were classified as sporadic EC, and 115 cases (26%) cases with loss expression of at least one MMR protein were regarded as probable LS. MMR-deficient cases mostly showed a loss of MLH1/PMS2 expression (42%), followed by the absence of MSH2/MSH6 (23%), MSH6 (17%), PMS2 (17%) and MSH6/MLH1/PMS2 (3%). Compared with the sporadic EC group, obesity was not found in probable LS group (body mass index<28 kg/m2) (P=0.040), and high tumor grade was common (P=0.012); There was no significant difference between the two groups in age, the incidence of diabetes or hypertension, family history of cancer or histological type, tumor location, the International Federation of Gynecology and Obstetrics (FIGO) stage, myometrial invasion, lymph node metastasis, lymphatic or vascular invasion (all P> 0.05). A higher tumor grade was more common in the MSH6 and PMS2 deficient groups. Conclusions Compared with sporadic EC, the absence of obesity, a high grade tumor are more common in probable LS cases.

Objective To investigate the influence of pregnancy and delivery on maternal graft and newborns after renal transplantatior.Method Two cases of successful pregnancy and delivery after renal transplantation were retrospectively analyzed and the literatures were reviewed.Result The first recipient received the immunosuppressive treatment,which was based on the mycophenolate after renal transplantation.Three years after transplantation,the recipient had the requirement of pregnancy,but there was no pregnancy without contraception for over one year.On the next month after the myocphenolate-based immunosuppressive regimen changed to the purine-based,B ultrasound revealed follicular growth,ovulation and pregnancy.Caesarean section was performed at 37 gestational weeks and a body was delivered.The weight of the boy was 2 750 g,and the Apgar scores of the newborn were 10.The second recipient received triple immunosuppressive therapy (cyclosporin A + azathioprine + methylprednisolone),and got natural pregnancy 4 years after renal transplantation.The recipient was hospitalized due to the increased blood pressure and reduced fetal heart rate at 33 W+2 gestational weeks,and discharged after treatment.Caesarean section was performed at 38 W+1 gestational weeks,the weight of the boy was 3 000 g,and the Apgar scores of the newborn was 10.After follow-up for 8 years old,there was on abnormity of the function of the transplanted kidney and the growth of the newborns.Conclusion Successful pregnancy and delivery are possible in renal transplant recipients with normal renal function.Regulating the immunosuppressive regimen appropriately,and treating the complications of pregnancy effectively can obtained the satisfactory outcome of pregnancy.

ABSTRACT

Objective To observe the clinical efficacy and adverse reactions of docetaxel and carboplatin 21 day regimen (TC)as second -or third -line in treatment of patients with advanced triple -negative breast cancer (ATNBC).Methods 37 ATNBC patients with anthracyclines resistance were given docetaxel 70mg/m2 ,the first day of intravenous drip,carboplatin AUC =5,through intravenous drip on the first day,21 days for a course of treatment, until disease progression or not tolerated or most received six cycles of chemotherapy.Results 147 cycles of chemo-therapy were completed in 37 patients,and the median chemotherapy cycle was 4 cycles.The efficacy and adverse reactions could be evaluated in all patients.Among them,complete remission (CR)in 0 patient,partial remission (PR)in 12 patients (32.43%),stable (SD)in 11 patients (29.73%),and progression (PD)in 14 patients (41.18%).The effective rate(CR +PR)was 32.43%.The disease control rate (CR +PR +SD)was 62.15%,median TTP was 3.9 months (95%CI:4 -8months),and median OS was 10 months.Until the end of follow -up,there were 3 patients with no progress.The main adverse reactions were hematological toxicity (51.53%)and gastrointestinal reaction (56.76%).Conclusion TC regimen is effective and safe in the treatment of patients with ATNBC.

ABSTRACT

Objective To investigate the clinical values of next-generation sequencing (NGS) technology in diagnosis of miscarried chorionic villi genetic disorders. Methods Patients who underwent miscarriage (n=87) were enrolled in this study. Among all patients, 32 cases were of recurrent miscarrage and 55 cases were of sporadic miscarriage. In all collected patients, 35 women were 35 years or older while other 52 women were less than 35 years old. Positive detection rate and the abnormal detection rate were compared between these two methods. Chromosomes abnormal rates were also compared among different types of miscarrage and different ages. All aborted villi tissue were analyzed by NGS of whole genome and G-band?ing karyotype. Results The successful detection rate of chorionic villi by NGS (100.00%) was higher than that of G-band?ing karyotype (74.71%), and the detection rate of abnormal chorionic villi by NGS (58.62%) was also higher than that of G-banding karyotype (50.77%). Three cases of chromosome structure anomaly were found in those 51 chromosome anomalies (5.88%). Other 48 cases of chromosome anomalies were aneuploidy anomalies (94.12%) include 39 cases of trisomy, 2 cases of double trisomy and 1 case of triple trisomy and 6 cases of monomer. On the other hand, 32 cases of chromosome aneuploi?dy anomalies were found in 33 chromosome anomalies by G-banding karyotype, which include 24 cases of trisomy, 2 cases of double trisomy, 1 case of triple trisomy, 5 cases of monomer and 1 case of chromosome structure anomaly. Most NGS re?sults (n=64) were in agreement with G-banding karyotype but with 1 case of discrepancy. Chromosomal abnormality rate de?tected by NGS in sporadic miscarrage group and recurrent spontaneous miscarrage group were 60.00%and 56.25%respective?ly. There was no significant difference (P>0.05). Chromosomal abnormality rate picked by NGS in women aged≥35 years old (71.43%) was higher than that in women<35 years old (50.00%) with statistically significant difference (P<0.05). Conclu?sion NGS technology showed highly accuracy in detecting chromosomal abnomality from villi tissue. Therefore, it could help to detect genetic disorders of miscarrage. It is useful to determine the reasons of miscarrage and guide the next pregnancy.
