ABSTRACT
【Objective】 To explore a new treatment of primary bilateral macronodular adrenal hyperplasia (PBMAH) and its efficacy. 【Methods】 Clinical data of 20 PBMAH patients treated in our hospital during Mar.2010 and Apr.2021 were retrospectively analyzed. All patients underwent laparoscopic subcutaneous displacement of vascularized adrenal. The clinical symptoms, plasma free cortisol, adrenocorticotrophic hormone (ACTH), and 24 h urinary free cortisol were regularly monitored after surgery. 【Results】 Of all 20 patients, 19 were followed up for 18 to 120 months (median 60 months). Three months after surgery, reexamination showed 1 patient had decreased plasma free cortisol and increased ACTH, but had no symptoms of low corticosteroids. After another 3 months, the plasma free cortisol and ACTH returned to normal. After 4 to 48 months, the parameters recovered in all patients and the clinical symptoms disappeared. 【Conclusion】 Laparoscopic vascularized adrenal displacement is a new and effective method for the treatment of PBMAH. It can alleviate the Cushing syndrome with no obvious adverse reactions.
ABSTRACT
Objective:To analyze the role of perfusion index(PI)in assessing the severity of neonatal illnesses.Methods:A total of 502 newborns admitted to the Department of Neonatology within 24 hours of birth at Xinxiang Central Hospital from October 2018 to July 2019 were recruited.Neonatal critical illness score(NCIS)was graded within 24 hours of admission, and newborns were categorized into non-critical(NCIS>90 scores), critical(NCIS 70-90 scores)and extremely critical(NCIS<70 scores). PI was monitored in all newborns within 24 hours of birth in a resting state.A total of 502 PIs were recorded, including 341 cases of non-critical, 110 cases of critical and 51 cases of extremely critical.Results:The medium PI [ M( P25, P75)] of newborns in non-critical, critical and extremely critical groups were 1.80(1.40, 2.60), 0.96(0.74, 1.43)and 0.65(0.41, 1.10), respectively.PI values in extremely critical group was significantly lower than those in critical group and non-critical group( P<0.05). The medium PI [ M( P25, P75)] of full-term newborns, moderate/late preterm newborns and extremely/very preterm newborns were 1.70(1.20, 2.70), 1.60(1.10, 2.30) and 1.35(0.80, 2.30), respectively.PI in full-term newborns was significantly higher than those in moderate/late preterm newborns and extremely/very preterm newborns( P<0.05). PI was moderately positively correlated with NCIS in newborns( r=0.791, P<0.01). The area under the receiver operating characteristic curve of NCIS predicted by PI value was 0.846, and the prediction sensitivity and specificity were 85.0% and 70.8% when PI was 0.56. Conclusion:PI is correlated with NCIS in newborns, which is able to reflect the severity of neonatal illnesses.A low PI indicates severe conditions of neonatal illnesses.
ABSTRACT
Objective To systematically evaluate the completion and implementation effect of the medium-long-term program for schistosomiasis control in Tianmen City, and to provide references for formulating the next-stage control plan. Methods According to "National Medium-long-term Plan for Prevention and Control of Schistosomiasis (2004-2015) Final Evaluation Scheme", data on population, livestock, and infection status of snails in Tianmen City from 2004-2019 was retrospectively collected database was established with Excel. SPSS 19.0 software was used for statistical analysis to evaluate the achievement of goals, and task completion and implementation effects. SaTScan was used to detect the aggregation area of schistosomiasis cases. Results From 2004 to 2019, Tianmen City completed the planned tasks. All 23 villages and towns in the epidemic area reached the transmission interruption standard. In 2004, the infection rate of schistosomiasis among the residents was lower than 0.01%, then decreased to 0 in 2015, with no acute cases occurring for 11 consecutive years. In 2004, the infection rate of farm cattle in the city was 3.5%, and it then decreased to 0 in 2011. The area of snails increased from 2.4735 million square meters in 2004 to 5.132 million square meters in 2010, and no infectious snails was detected after 2009. The awareness rate of schistosomiasis knowledge and correct behavior formation rate of primary and secondary school students and housewives in the city exceeded 95%. Through spatial distribution analysis, schistosomiasis cases in Tianmen City showed a certain aggregation. Conclusion The medium-long-term program for the prevention and control of schistosomiasis in Tianmen City from 2004 to 2019 achieved the expected results. The overall epidemic situation declined year by year, but schistosomiasis control still faces many challenges.
ABSTRACT

ABSTRACT
Objective To study the risk factors of mortality in severe sepsis and septic shock patients. Methods 142 patients with severe sepsis and septic shock in ICU were observed and divided into alive group (98 patients)and dead group (44 patients)by using hospital mortality.The risk factors of mortality in severe sepsis and septic shock patients were assessed by binary logistic regression.Results Independent mortality risk factors were inotropic agents (OR =4.329,95%CI:1.045 -17.937,P =0.043),blood glucose >10 mmol/L (OR =3.771,95%CI:1.214 -11.710,P =0.022)and APACHE Ⅱ score (OR =3.098,95%CI:2.012 -4.760,P =0.000),while PaO2 /FiO2 after early goal -directed therapy (EGDT)was protective factor (OR =0.682,95%CI:0.500 -0.930, P =0.016).Conclusion Severe sepsis and septic shock patients with inotropic agents,blood glucose >10mmol/L, high APACHE Ⅱ score and decreased PaO2 /FiO2 after EGDT indicate poorly prognosis.
ABSTRACT
ObjectiveTo discuss the changes in characteristics of N-glycan in gastric cancer and its relationship with TCM syndromes.Methods The blood samples of 138 gastric cancer patients and 120 healthy volunteers were collected. The changes in N-glycan were detected by DNA sequencer-assisted and fluorophore-assisted carbohydrate electrophoresis (DSA-FACE), and differences of N-glycan among different TCM syndromes were compared.Results At least 9 N-glycan peaks could be identified in all samples. Compared with the healthy volunteers, Peak1, Peak5, Peak9 and Peak2 of gastric cancer patients obviously increased (P<0.05,P<0.01), whereas Peak3, Peak6 significantly decreased (P<0.01). Peak6 of gastric cancer in stage I was obviously higher than stages II, III, and IV (P<0.01), while Peak9 in stage I was obviously lower than the other three stages (P<0.01). Peak1 was significantly lower in disharmony between liver and stomach type than stagnation of phlegm-dampness type, interior retention of toxin stagnation type, deficiency of both Qi and blood type (P<0.05,P<0.01);lower in impairment of yin due to stomach heat type, deficiency-cold in spleen and stomach type than deficiency of both Qi and blood type (P<0.01);lower in stagnation of phlegm-dampness type, interior retention of toxin stagnation type than deficiency of both Qi and blood type (P<0.05). Peak6 was higher in disharmony between liver and stomach type than impairment of yin due to stomach heat type, stagnation of phlegm-dampness type, interior retention of toxin stagnation type than deficiency of both Qi and blood type (P<0.01). Peak9 was much higher in deficiency of both Qi and blood type than disharmony between liver and stomach type (P<0.01), impairment of yin due to stomach heat type and deficiency-cold in spleen and stomach type (P<0.05, P<0.01).Conclusion The expression of N-glycan was specifically changed in gastric cancer. These variations could promote the metastasis of gastric cancer and potentially have certain correlation with TCM syndromes.
ABSTRACT
Objective To analyze the curative effect of traditional Chinese medicine(TCM)combined with early enteral nutrition(EN)for treatment of patients with severe acute pancreatitis(SAP). Methods 70 SAP patients were randomly divided into TCM plus EN group(36 cases)and conventional therapy group(34 cases). Both groups received routine treatment. Additionally,TCM+EN group received early EN and TCM decoction treatment〔the ingredients of decoction including radix bupleuri,radix paeoniae alba,radix scutellariae,fructus aurantii immaturus, magnolia bark,raw rhubarb(rhubarb was added at last during cooking the decoction)and natrii sulfas exsiccatus (dissolved in water to be administered)each 10 g,the decoction was concentrated to 150 mL and then administered via a stomach tube to the patient,afterwards the tube was clipped for 2.5-3 hours,twice a day,4-7 days constituting a therapeutic course〕. After treatment,the time for patients' symptoms improvement,the situation of intestinal recovery, the length of stay in hospital,the total medical cost,serum C-reactive protein(CRP),aspartate aminotransferase (AST), lactate dehydrogenase (LDH), amylase (AMY), acute physiology and chronic health evaluationⅡ(APACHEⅡ)score and complications,intensive care unit(ICU)transfer rate and case fatality rate in two groups were observed. Results The time for symptoms improvement of abdominal tenderness(day:1.68±1.01 vs. 3.89±1.07), abdominal distension(day:2.17±1.48 vs. 4.24±3.23),abdominal pain(day:3.12±1.14 vs. 4.94±3.21)and the intestinal recovery of exhaust defecation time(day:3.48±0.92 vs. 5.32±3.30)of SAP patients after treatment in the TCM+EN group were faster significantly than those in the conventional therapy group(all P0.05). Among the 70 patients with SAP,the cause of the disease due to gallstone accounted for 55.72%,hyperlipidemia for 37.14%,alcoholic for 4.28%and other 2.86%. Conclusion The use of TCM combined with early EN for treatment of patients with SAP can enhance the curative effect of SAP,reduce the hospitalization time and the total cost of patients,and decrease complications and mortality,that is conducive to the faster recovery of patients.
ABSTRACT
Objective To investigate the changes of Claudin-3 and Claudin-11,two key components of blood-testis barrier (BTB) on male infertility induced by γ-ray irradiation.Methods Fortytwo KunMing male mice (20-25 g) were divided into one control group,three γ-ray irradiation groups and three estrodiol (E2) intervention groups randomly:Group A,sham controlled; the lower abnominal and scrotal area of the mice in Group B,C,D were irradiated with single dose of 2,6 or 10 Gy 60Co γ-ray after anaesthetizd; 17β-estradiol intervention were initiated in Group E,F,G after 6 Gy γ-ray irradiation via hypodermic injection for 4w at the dose of 1,2,4 μg/d,respectively.Mice were sacrificed 2 w after the last E2 administration.The tubule differentiation index (TDI) was counted in testis sections.InhibinβB,Claudin-3 and Claudin-11 transcription levels were assayed with semiquantitative real time PCR.Claudin-11 protein levels in testis were generated by western blot.Results Compared with sham control group,TDI in three γ-ray irradiation groups were markedly reduced (68.5 ± 6.4,35.0± 6.1,16.3 ± 5.7 vs 100.0,all P<0.05).InhibinββB mRNA expression level in testis of gourp D was markedly decreased (0.5±0.2 vs 1.0±0.1,P<0.05).Claudin-3 mRNA levels of group C and D were up-regulated to 2.17 and 3.49 times,respectively.Claudin-11 protein levels were significantly increased to 2.18 and 2.23 times.Compared with group C,TDI in three E2 intervention groups were improved,which were obvious in group F and G (61.7±7.2,55.8±11.9 vs 35.0±6.1,P<0.05).The InhibinβB mRNA levels were increased,though there were no significant differences (all P >0.05).Claudin-3 mRNA levels in group F and G were down-regulated (1.3± 0.2,1.6±0.3 vs.2.2 ± 0.2,all P<0.05).In group F significantly reduced mRNA level and protein level of Claudin-11 were observed (mRNA:1.2±0.2 vs.1.8±0.2,P<0.05; Protein:1.5±0.5 vs.2.2±0.3,P<0.05).It was negatively correlated TDI with mRNA expression levels of Claudin-3 and Claudin-11 in the irradiated testis (rs =-0.884,P<0.05; rs=-0.758,P <0.05,respectively).Conelusions Irradiation could elevated the expression of claudin-3 and claudin-11.

ABSTRACT
ObjectiveTo establish a new model of biliary peffusion in vitro,and to explore the feasibility of comparative biliary studies with the model.MethodsA set of ten-text-area model of biliary peffusion was designed in vitro.Saline,glycerol and pig bile were put into this model.The outflow of the first tube was set at 8 drops/min,and these liquids were collected through the ten sample test areas and measured at 0.5 hour,1.0 hour,1.5 hours,2.0 hours,12.0 hours and 24.0 hours.Equality of liquid amount was evaluated from each sample test area.Rods containing delayed release EDTA of ten different levels were placed in the test areas.The liquid was collected and EDTA concentrations were evaluated from the ten tubes at 24.0 hours.EDTA concentrations of the same rod in the three liquids were compared.ResultsA(1) the same time point,the amounts of saline,glycerol,pig bile flowing through the ten sample test areas showed no significant difference (P > 0.01 ) ; but EDTA concentrations of the same liquid at 24.0 hours were significantly different (P < 0.01 ) ; and EDTA concentrations of the same rod in the three liquids were also obviously different ( P < 0.01 ).ConclusionThe same liquid flow rates and the same experimental environment can be achieved.Different test results can be obtained from different test areas in different experiments.The test results of the same kind of sample change with the changes of experimental conditions,which simulates biliary duct.

ObjectiveTo investigate the surgical management of left renal vein entrapment syndrome.MethodsEight cases with left renal vein entrapment syndrome (5 males and 3 female ; mean age 26 years) with history of gross hematuria for 3 to 46 months were reviewed.Doppler ultrasound reports suggested compression of the left renal vein at mesenteric angle in all cases.And the dilated segment of the left vein was three-fold than the stricture segment in diameter.CT scan showed the abnormal angle between aorta and superior mesentery artery in all cases.Bleeding from the left ureteral orifice was detected by cystoscopy in 6 cases.We treated 8 patients by extravascular stent immobilization with laparoscope.ResultsThe operation was successful in the 8 cases without surgical complications.The average operation time was 63 min.The average blood loss was 14 ml,and the average hospital stay after operation was 6 days.Follow-up of 3 -20 months,there was no hematuria relapse since been relieved in 7 cases,one case remained microscopic hematuria.Color Doppler ultrasound examination in all 8 cases showed the narrowest inner diameter of left renal vein was 7.4 mm (6.5 - 8.7 mm),the blood flow was smooth.The angle between abdominal aorta and superior mesenteric artery become normal.Conclusions Laparoscopic left renal vein extravascular stenting could be a new surgical method to treat left renal vein entrapment syndrome.The method of putting artificial blood vessel around renal vein is simple,safe and effective.
