Objective To study clinical efficacy of ganciclovir in the therapy of infectious mononucleosis in adults.Methods 66 adults with infectious mononucleosis in a hospital from January 2010 to December 2014 were studied retrospectively,according to drug therapy,patients were divided into ganciclovir therapy group(n=31)and symptomatic therapy group(n=35),clinical features before therapy,therapeutic efficacy,and Epstein-Barr virus(EBV)DNA negative conversion time were analyzed.Results The time of defervescence,sore throat improvement,EBV-DNA negative conversion,subside of enlarged lymph node,and transaminase recovery in ganciclovir therapy group were all shorter than symptomatic therapy group(all P<0.05).Blood routine recovery time between two groups was not significantly different(P>0.05).Conclusion Ganciclovir has a good antiviral effect on the therapy of adult infectious mononucleosis,it can rapidly relieve patients from clinical symptoms including fever,sore throat and so on.

Objective To investigate the clinical features of patients with multiple sclerosis (MS) and restless legs syndrome (RLS) and to further examine relevant factors that may contribute to the co-occurrence of MS and RLS.Methods Seventy MS patients were recruited in the present study.The RLS screen was further performed in MS patients based on the diagnostic criteria for RLS.MS patients with RLS were designated as the case group and MS patients without RLS served as the control group.The clinical data including age of MS onset,MS duration and clinical disability by the expanded disability status scale (EDSS) were analyzed.Results There were 12 MS patients with RLS in total 70 MS patients and the incidence rate was 17.1％.The average age of MS onset in the RLS group was (47.6 ± 10.0) years,and (40.1 ± 10.4 ) years in the control group.The difference of average age of MS onset was found to be significant (t =2.29,P =0.030).The average history of MS in the RLS group was ( 12.6 ± 6.8 ) years,and ( 8.2 ± 6.6) years in the control group ( t =2.10,P =0.039).The average EDSS of the RLS group was 4.5 ±2.5,and 2.5 ±2.0 in the control group (t =3.02,P =0.004).There was no significant association between RLSRS and EDSS in MS patients with RLS (P =0.15).Conclusion The incidence rate of RLS in MS patients was high.Among patients with MS,RLS was associated with older age,longer MS duration,and more severe disability.

Objective To analyze the occurrence status and influencing factors of esophageal stenosis after surgery for early esophageal cancer. Methods A total of 285 patients with early esophageal cancer with endoscopic submucosal dissection (ESD) in the hospital from January 2019 to January 2021 were selected as research objects, and they were divided into control group with 237 cases (without esophageal stenosis) and study group with 48 cases (with esophageal stenosis) according to the occurrence of esophageal stenosis after surgery. The operation time, intraoperative blood loss and quality of life were compared between the two groups. The influencing factors of esophageal stenosis were analyzed. Results Compared with the control group, the study group had longer operation time, more intraoperative blood loss, and lower scores in psychological, environmental, physiological and social dimensions, and the between-group differences were statistically significant (P<0.05). Univariate analysis showed that esophageal stenosis after ESD had no correlations with gender, clinical stage, pathological type, history of drinking, the American Society of Anesthesiologists (ASA) classification, and anesthesia method (P>0.05). Patients aged ≥60 years old, damage of the muscularis propria, circumferential extent of lesion >3/4, malnutrition, tissue infiltration depth of M3+SM1, and longitudinal length of lesion >40 mm had a higher incidence of esophageal stenosis (P<0.05). Multivariate Logistics regression analysis showed that malnutrition, age ≥60 years, circumferential extent of lesion >3/4, damage of the muscularis propria, tissue infiltration depth of M3+SM1, and longitudinal length of lesion >40 mm were the main influencing factors for esophageal stenosis after ESD (P<0.05). Conclusion The occurrence of esophageal stenosis after ESD in patients with early esophageal cancer is related to factors such as damage of the muscularis propria, malnutrition, age ≥60 years, tissue infiltration depth of M3+SM1, circumferential extent of lesion >3/4, and longitudinal length of lesion >40 mm. Based on these factors, early prevention and control can be carried out to reduce the incidence of esophageal stenosis after surgery.

OBJECTIVETo investigate the correlation between CT image presentations and biochemical indexes in adrenal adenomas and pheochromocytomas.

METHODSWe retrospectively analyzed the CT features, cortisol rhythm, supine and orthostatic hypertension and 24-h urine methoxy in 209 patients with benign adrenal tumors. The relationship between CT findings and the biochemical indexes were analyzed in patients with different benign adrenal tumors.

RESULTSThe 209 cases analyzed included 53 cases of cortisol adenoma, 65 cases of aldosterone adenoma, 45 cases of non-functional adenoma and 46 cases of pheochromocytomas. The plain CT scan values of the 4 groups were 17.25 ± 1.81, 14.52 ± 1.57, 12.20 ± 2.05, 42.42 ± 0.97 HU, enhanced CT values (arterial phase) were 47.82 ± 3.07, 39.23 ± 2.37, 45.35 ± 6.46, and 104.93 ± 5.84 HU, respectively, and the differences between CT scan and enhanced CT values were 30.58 ± 2.29, 24.71 ± 1.55, 33.15 ± 5.18, and 62.51 ± 5.73 HU, respectively. In cortisol adenoma group, cortisol levels measured at 16:00 and 24:00 were positively correlated with plain CT scan value (r=0.506, P=0.0001; r=0.504, P=0.0001) and enhanced CT value (r=0.514, P=0.0001; r=0.554, P=0.0001). In pheochromocytoma group, plain scan CT value and the difference between plain and enhanced CT scan value were correlated with 24-h urine methoxy adrenaline (Rho;=0.342, 0.350; P=0.020, 0.017, respectively) and norepinephrine (Rho;=0.419, 0.412; P=0.004, 0.004, respectively).

CONCLUSIONPlain and enhanced CT scan values and their combination have important value in differential diagnosis of adenoma and pheochromocytoma tumor, CT values combine with biochemical indexes can reduce misdiagnosis and missed diagnosis of pheochromocytoma.

As a member of the sirtuins family, also called Class III histone deacetylases (HDACs), SIRT6 has many catalytic enzyme activities and plays a pivotal role in biological processes including anti-aging, chromatin regulation, transcriptional control, glucose and lipid metabolism, and DNA damage repair. Recently, increasing evidences indicated that SIRT6 was related to initiation and development of tumors, such as hepatic cancer, lung cancer, breast cancer and genital system tumors. However, SIRT6 might play a dual role in tumorigenesis and progression. SIRT6 often acted as a tumor suppressor, but might play an oncogenic role. Based on our current study, we depicted the essential roles of SIRT6 in the initiation and progression of various tumors, and summarized its mode of actions, which might provide clues for cancer therapy.

ObjectiveTo investigate the protective mechanism of Qianyang Yuyin granules （QYYY） on aldosterone-induced podocyte injury. MethodA total of 30 C57BL/6J mice were randomly divided into five groups： control group， model group， QYYY low dose （QYYY-L） group， QYYY high dose （QYYY-H） group， and spironolactone （SPL） group， with six mice in each group. Except for the control group， mice were implanted with osmotic minipumps and injected continuously with aldosterone （300 μg·kg^-1·d^-1） to induce renal injury. The drug administration group was given low and high doses （2.6， 5.2 g·kg^-1·d^-1） of QYYY and SPL （18 mg·kg^-1·d^-1） for 28 days. The renal pathological changes of mice were observed by hematoxylin-eosin （HE） staining and Masson staining. The expression levels of Nephrin， Desmin， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X （Bax）， cleaved Caspase-3， nuclear receptor subfamily 3 group C member 2 （NR3C2）， extracellular regulated protein kinases （ERK）， and phospho-ERK （p-ERK） in kidney tissue were detected by Western blot. The apoptosis levels of kidney tissue were detected by TdT-mediated dUTP nick and labeling （TUNEL） staining， and the superoxide dismutase （SOD） levels were detected. In vitro， the mice were divided into five groups： Control group， model group （aldosterone concentration of 200 nmol·L^-1）， QYYY-L group， QYYY medium dose （QYYY-M） group， and QYYY-H group （25， 50， and 100 mg·L^-1）. The effect of different concentrations of QYYY on the relative viability of aldosterone-induced podocytes was detected by cell proliferation and viability assay （CCK-8）. The expressions of Nephrin， Desmin， Bax， Bcl-2， cleaved Caspase-3， NR3C2， and p-ERK/ERK were detected by Western blot. AnnexinV-FITC/PI flow cytometry was used to detect the apoptosis levels of podocytes. Reactive oxygen species （ROS） in podocytes were observed by DCFH-DA. ResultCompared with the control group， the model group showed structural pathological changes and fibrotic conditions in the kidney， increased apoptosis levels （P<0.01）， and decreased SOD levels （P<0.01）. Aldosterone concentration at 200 nmol·L^-1 showed a significant decrease in podocyte activity （P<0.05）. Podocytes in the model group showed structural pathological changes， disordered arrangement of intercellular microfilaments， increased apoptosis levels （P<0.01）， and increased intracellular ROS levels （P<0.01）. The protein expressions of Nephrin， Bcl-2， and p-ERK/ERK in kidney tissue and podocytes were decreased （P<0.05， P<0.01）. The protein expressions of Desmin， Bax， cleaved Caspase-3， and NR3C2 were increased （P<0.05， P<0.01）. Compared with the model group， QYYY alleviated the structural damage and fibrosis of the kidney， decreased the apoptosis levels （P<0.05， P<0.01）， and enhanced the SOD content of the kidney （P<0.05， P<0.01）. QYYY improved the activity of podocytes （P<0.05， P<0.01）， restored the foot process structure of podocytes， and decreased apoptosis levels （P<0.01） and ROS levels of podocytes （P<0.01）. The protein expressions of Nephrin， Bcl-2， and p-ERK/ERK in kidney tissue and podocytes were increased （P<0.05， P<0.01）， and the protein expressions of Desmin， Bax， cleaved Caspase-3， and NR3C2 were down-regulated （P<0.05， P<0.01）. ConclusionQYYY improves aldosterone-induced podocyte injury by regulating the NR3C2/ROS/ERK pathway.
