Objective To investigate the clinical efficacy and ultrasonographic changes treated with anti-thyroid drugs ( ATD ) in patients with primary hyperthyroidism(PHT).Methods 83 cases of PHT patients admitted to the department of ultrasound from February 2013 to August 2015 in Zhuji People's Hospital of Zhejiang Province were selected, the patients were divided into two groups according to the results of ultrasonography, echo nonuniform group 41 cases and echo uniform group 42 cases.ATD therapy was administered to the both groups (were treated with methimazole).The thyroid related indexes and hemodynamics of thyroid right superior diagnosed by color doppler ultrasound, and the curative efficacies of the two groups were analyzed.Results After treatment, the systemic vascular resistance index(RI) of echo uniform group was (0.62 ±0.17), and the echo nonuniform group was (0.65 ±0.18), there was no significant difference between the two groups.The echo uniform group of thyroid artery diameter on the right lobe(D), the peak systolic velocity(Vmax), minimum diastolic blood flow velocity(Vmin), thyroid volume(V) and blood flow volume(Q) were significantly lower than the echo nonuniform group, the difference was statistically significant (P <0.05).The total effective rate of the echo nonuniform group (48.78%) was significantly lower than that in the echo uniform group (85.71%), the difference was statistically significant(P <0.05).Conclusion ATD has a good effect in treating PHT, and can significantly improve the thyroid hemodynamics in patients, it has a positive effect on the regulation of thyroid-related parameters in patients, the clinical treatment is effective, and the effect is better especially in patients with uniform echo.

Objective To study the effect of serum leptin in “two hits” of nonalcoholic fatty liver disease (NAFLD).Methods Fasting serum leptin(LEP) ,malondialdehyde(MDA) ,hyaluronic- acid(HA) ,type Ⅲ procollagen ( PCⅢ), laminin ( LN), and type Ⅳ collagen ( Ⅳ-C ) were detected in 43 simple nonalcoholic fatty liver( NAFL ) patients ,41 NASH patients and 40 healthy subjects. Insulin resistance was estimated by HOMA value and its relatio nship with leptin level in NAFLD was analyzed. The severity of lipid peroxidation was estimated by MDA and its relationship with leptin level in NAFLD was analyzed. The relationship of serum fibrosis markers with leptin level in NAFLD also was analyzed. Results Serum leptin, HOMA value in NAFLD were higher than those of healthy controis. MDA,PC Ⅲ 、Ⅳ-C 、LN 、HA in NASH were higher than those of healthy controls or simple NAFL patients. ,HOMA value, in NAFLD positively correlated with leptin. MDA, PC Ⅲ、 Ⅳ-C 、LN、HA in NASH positively correlated with leptin. Conclusion Serum leptin closely correlated with insulin resistance which results in “First hit” of NAFLD. There was certain relationship of leptin with “Second hit” of NAFLD. Leptin should be one of the factors which result in liver fibrosis.

Objective To investigate the characteristics of blood glucose fluctuation of continuous ambulatory peritoneal dialysis (CAPD) patients with end stage diabetic nephropathy(ESDN) attaining glycated hemoglobin standard. Methods The study recruited 17 patients with type 2 diabetes attaining glycated hemoglobin standard, and used continuous glucose monitoring system (CGMS) to monitor glycemic variation for 72 h. General information was collected and biochemical indexes were determined. Results The mean amplitude glycemic excur-sions (MAGE), standard deviation ,mean blood glucose levels, maximum of blood sugar, and the proportion of greater than 13.9 mmol/L in peritoneal dialysis patients were (8.36 ± 4.44) mmol/L, (3.38±1.08) mmol/L, (9.88±1.92) mmol/L, (17.95±13.11)%, which were significantly higher than those in normal. The mean amplitude glycemic excur-sions (MAGE), standard deviation ,mean blood glucose levels, maximum of blood sugar, and the proportion of greater than 13. 9 mmol/L in daytime were (8.25± 3.71) mmol/L, (2.83±0.89) mmol/L, (11.32±2.54) mmol/L, (16.61±3.86) mmol/L, (28.45±19.56)%, which were significantly higher than those in nighttime: (4.20±2.67) mmol/L, (1.34±0.89) mmol/L, (7.02±1.92) mmol/L, (9.61±2.77) mmol/L, (5.31±1.28)%, all P<0.05. The minimum and the proportion of less than 3.9 mmol/L between the two groups had no significant difference ( P>0.05). Besides, biochemical glycosylated hemoglobin was less than the calculated from CGMS: (5.88± 0.73)%vs. (7.85±1.20)%, t=4.76, P<0.01. Conclusions Peritoneal dialysis patients with ESDN have an increased glycemic fluctuation and a unsatisfied glycemic control, which is worse in daytime. Glycosylated hemoglobin is undervalued. Glycosylated hemoglobin should not be simply used on hemodialysis patients with ESDN to evaluate whether they have a good glycemic control. CGMS can better describe their blood sugar condition.

Objective: To evaluate the effectiveness of enteral nutrition in children with accidental upper gastrointestinal injury. Methods: The medical records of 128 patients with mechanical or chemical gastrointestinal mucosal injury, who were hospitalized in Department of Gastroenterology, Children's Hospital of Zhejiang University School of Medicine from January 1, 2011 to December 30, 2017, were collected. All cases were treated with enteral nutrition. The clinical features and etiologies were retrospectively analyzed. Weight-for-age Z score and lab findings including white blood cells, C-reactive protein, neutrophils, albumin, prealbumin, urea nitrogen and hemoglobin before and after treatment were extracted. The clinical characteristics, the duration of enteral nutrition and gastrointestinal mucosal healing between different etiologies were further analyzed. Normal distribution variables and categorized variables were compared with t test and χ² test respectively, and abnormal distribution data was compared with Wilcoxon test. Results: Among all the cases, 77 were males and 51 were females. The average age was (29±22) months. The mean duration of hospitalization and enteral nutrition were (11±7)d and (27±20)d respectively. Vomiting was the most common clinical presentation (72 cases, 56.3%). In 79 cases the problems were caused by mechanical injury, among which coins were most commonly seen. The rest 49 cases were caused by chemical injury. However, the duration of hospitalization ((13±8) d vs. (10±6)d, t=-3.089, P=0.002) and enteral nutrition ((39±22) vs. (19±14) d, t=-5.365, P=0.000) were longer in children with chemical injury than those with mechanical injury. A total of 112 cases got complete blood count and C-reactive protein both before and after enteral nutrition. Inflammatory markers, including leukocytes ((7.7±2.7) ×10⁹/L vs. (13.7±5.0) ×10⁹/L, t=12.244, P <0.05), neutrophils ((3.4±1.9)×10⁹/L vs. (9.4±4.6) ×10⁹/L, t=13.655, P<0.05), and C-reactive proteins (5.0(3.0,7.8) vs. 13.5(6.0,40.5) mg/L, Z=7.776, P <0.05) were significantly decreased. The nutritional markers, including the weight-for-age z score (-0.1 ± 1.0 vs. 0.0 ± 1.0, t=-2.622, P=0.010) and the prealbumin (0.1 ± 0.1 vs. 0.2 ± 0.0 g/L, t=-3.671, P=0.001) were significantly increased. Fifty-five (82.1%) children in mechanical injury group recovered in 4 weeks, while 27 (79.4%) children in chemical injury group recovered in 7 weeks. Conclusion Enteral nutrition can provide adequate nutritional requirements for children with upper gastrointestinal injury, and may help to decrease imflammation and improve mucosal healing.

Objective:To compare and analyze the technical success rate and safety between computed tomography(CT)-percutaneous radiological gastrostomy (PRG) and percutaneous endoscopic gastrostomy (PEG).Methods:From January 2017 to January 2022, at the First Affiliated Hospital of Zhengzhou University, the data of 76 patients who underwent gastrostomy due to inability to eat orally were collected, including 38 patients in PEG group and 38 patients in CT-PRG group. Surgical outcomes and complications were compared between the PEG and CT-PRG groups. Surgical outcomes included technical success rate, operation time, postoperative body mass index and hospital stay; while complications included minor complications (such as perifistula infection, granulation tissue proliferation, leakage, pneumoperitoneum, fistula tube obstruction, fistula tube detachment and persistent pain) and serious complications (such as bleeding, peritonitis, colonic perforation and death within 30 d). Independent sample t test, chi-square test, and Fisher exact probability test were used for statistical analysis. Results:The technical success rate of CT-PRG group was higher than that of the PEG group (100.0%, 38/38 vs. 78.9%, 30/38), and the operation time was shorter than that of the PEG group ((17.16±8.52) min vs. (29.33±16.22) min), and the differences were statistically significant ( χ2=1.19, t=2.36; P=0.038 and 0.011). There were no significant differences in postoperative body mass index ((16.29±3.56) kg/m 2 vs. (16.12±3.17) kg/m 2) and hospital stay ((4.13±1.26) d vs. (3.52±1.13) d) between PEG group and CT-PRG group (both P>0.05). The incidence of minor complications in the PEG group was 42.1% (16/38), including 6 cases of perifistulal infection, 1 case of leakage, 5 cases of fistula tube obstruction, 1 case of fistula tube detachment, and 3 cases of persistent pain. The incidence of serious complications was 5.3% (2/38), including 1 case of bleeding and 1 case of colonic perforation. The incidence of minor complications in the CT-PRG group was 39.5% (15/38), including 5 cases of perifistula infection, 1 case of granulation tissue proliferation, 3 cases of pneumoperitoneum, 3 cases of fistula tube obstruction, 2 cases of fistula tube detachment, and 1 case of persistent pain. The incidence of serious complications was 0. There was no significant difference in the incidence of minor complications between the PEG group and the CT-PRG group ( P>0.05), while the incidence of serious complications in the CT-PRG group was lower than that of the PEG group, and the difference was statistically significant (Fisher exact probability test, P=0.043). Conclusion:PEG is a safe and effective method of gastrostomy, but for patients with esophageal obstruction, CT-PRG can be an effective supplement to PEG.

Objective:To analyze the clinical characteristics of monkeypox patients.Methods:The clinical data and laboratory findings of 4 patients with monkeypox patients diagnosed at Yiwu Central Hospital in July 2023 were analyzed. Herpes fluid and skin tissue samples were collected, the viruses were isolation and cultured in African green monkey kidney cells (Vero) and identified with whole gene sequencing.Results:All four patients were male, aged 24-35 years. All patients had male-to-male behavior within 21 days before onset of the disease. Among them, one patient has AIDS and one patient has syphilis. Four patients presented with perineal skin lesions with itching, and 3 patients were found to have enlarged lymph nodes upon admission. Laboratory testing: lymphocyte abnormality (4.57×10 9/L) in 1 case; increased procalcitonin (0.25 ng/mL) in 1 case; elevated IL-10 levels ( 7.11 ng/L and 9.42 ng/L) in 2 cases; increased IL-6 (66 ng/L) and IL-4 (3.24 ng/L) in 1 case, respectively. One case had abnormal myocardial zymogram with a elevated lactate dehydrogenase level of 313 U/L. The monkeypox virus was isolated from lesion tissue and herpes fluid, and the whole gene sequencing identified it as the B. 1.3 subtype of the IIb evolutionary branch, exhibiting typical pathological effects on Vero cells. Conclusion:The clinical manifestations of the 4 monkeypox patients confirmed in Zhejiang province are mild, patients had a definitive history of male-to-male sexual behavior and the virus strains belong to the B. 1.3 lineage of the IIb evolutionary branch.

Objective To analyze the relationship of neurocognitive impairments and 1 H MRS changes of the thalamus in patients with chronic hepatitis B virus related cirrhosis (HBV-RC).Methods Totally 28 patients with HBV-RC (cirrhosis group) and 28 well-matched healthy subjects (control group) were enrolled.All subjects underwent number connection test A (NCT-A) and the digit symbol test (DST) before MRS scanning.The ratios of peak area to each metabolite,including N-acetylaminosuccinic acid (NAA),choline (Cho),glutamine and glutamate (Glx),myoinositol (mI) and creatine (Cr) were calculated,respectively.Results Compared with control group,patients in cirrhosis group showed lower Cho/Cr and mI/Cr,higher Glx/Cr,prolonged NCT-A time and decreased DST scores (all P＜0.001).NCT-A completion time was negatively correlated with Cho/Cr and mI/Cr (r=-0.477,P =0.001;r=-0.695,P＜0.001) and positively correlated with Glx/Cr (r=0.665,P＜0.001).DST scores were positively correlated with Cho/Cr and mI/Cr (r =0.478,P =0.001;r=0.632,P＜0.001),and negatively correlated with Glx/Cr (r=-0.572,P＜0.001).Conclusion The neurocognitive impairments may be related to metabolic changes of the thalamus in patients with HBV RC.
