Acute pancreatitis is considered an autodigestive disorder in which inappropriate activation of trypsinogen to trypsin within pancre-atic acinar cells leads to the development of pancreatitis.Autophagy is an evolutionarily preserved degradation process of cytoplasmic cellular constituents,and it is one of the early pathological processes in acute pancreatitis.Autophagic flux is impaired in acute pancreatitis,which mediates the key pathologic responses of this disease.Impaired autophagy,dysfunction of lysosomes,and dysregulation of autophagy suggest a disorder of the endolysosomal pathway in acute pancreatitis.The role of autophagy in acute pancreatitis is discussed from the aspects of au-tophagic process,autophagy and activation of trypsinogen,impaired autophagy and acute pancreatitis,and defective autophagy promoting in-flammation.

Objective To investigate diagnostic approaches of cervical glandular intraepithelial neoplasia (CGIN) for improving the diagnostic levels of CGIN.Methods Clinical data of 106 cases with CGIN admitted in hospital from Jan.2008 to Dec.2010 were analyzed retrospectively.All data from preoperative thin-prep cytologic test (TCT),cervical biopsies and postoperative pathological examination of the excised cervical tissues were reviewed.Results Among 106 patients,62 cases (58.5％,62/106) were low grade CGIN (L-CGIN),44 cases (41.5％,44/106) were high grade CGIN (H-CGIN) ; 25 cases (23.6％,25/106) were pure CGIN and 81 cases (76.4％,81/106) were CGIN mixed with cervical intraepithelial neoplasia (CIN).Fifteen cases (14.2％,15/106) were found atypical glandular cell (AGC)by TCT..In the 15 cases,there were 4 cases (6.5％,4/62) L-CGIN,and 11 cases (25.0％,11/44)H-CGIN,there was significant difference between the two groups (P ＜ 0.05) ; among 15 cases with AGC,11 cases of them (44.0％,11/25) were pure CGIN,4 cases (4.9％,4/81) mixed with CIN,in which there were significant difference (P ＜0.01).Seven cases (25.0％,7/28) were detected glandular lesions in 28 cases by endocervical curettage (ECC).Totally 23 cases (22.8％,23/101) were detected CGIN by colposcopy-directed biopsy,11 cases (19.0％,11/58) were with L-CGIN,12 cases (27.9％,12/43)H-CGIN,there was no significant difference between them (P ＞ 0.05).Among the 23 cases,13 eases(52.0％,13/25) were pure CGIN,10 cases (12.3％,10/81) CGIN mixed with CIN,which showed significant difference (P ＜ 0.01).All 106 patients were treated,101 cases treated with cervical conization and 5 cases performed hysterectomy; 23 cases were diagnosed CGIN preoperation,the ratio of preoperative diagnosis was 21.7％ (23/106),83 cases (80.3％,83/106) diagnosed postoperatively.Conclusions Routine diagnostic methods of CGIN were not satisfaction,most CGIN were diagnosed after cervical resection.Cervical conization may play a very important role in diagnosis of CGIN.The positivity of TCT in H-CGIN was higher than L-CGIN.There was no different in diagnosing different CGIN grades by colposcopy-directed biopsy.The ratio of preoperative diagnosis of pure CGIN was higher than those with CGIN mixed with CIN.

Objective To investigate the value of cysteine-rich secretory protein LCCL domain-containing 2 (CRISPLD2) in diagnosis and prognosis in patients with sepsis.Methods Clinical data of patients admitted to intensive care unit (ICU) of the First Hospital of Hebei Medical University from December 2014 to December 2016 were retrospectively analyzed. According to the severity of sepsis, the patients were divided into three groups: sepsis patients, severe sepsis patients and septic shock patients, and 100 healthy persons were enrolled as control group. Levels of serum CRISPLD2, procalcitonin (PCT) and C-reactive protein (CRP), acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, and 28-day prognosis were recorded. Analysis of the correlation between CRISPLD2 and PCT, CRP, APACHEⅡscore, SOFA score was done. The receiver operating characteristic (ROC) curve was plotted for the CRISPLD2 value for the diagnosis and prognosis in patients with sepsis.Results A total of 115 patients with sepsis were enrolled in this study, including 52 sepsis, 48 severe sepsis, and 15 septic shock; 29 patients died after 28 days, 28-days mortality rate was 25.2%. There was no significant difference in CRISPLD2 between sepsis and healthy control group (mg/L: 204.1±74.5 vs. 211.3±12.0, P > 0.05); the level of CRISPLD2 in septic shock group was significantly lower than that in sepsis group and severe sepsis group (mg/L: 139.0±55.0 vs. 240.2±89.6, 233.0±8.9, bothP < 0.05). The level of PCT, CRP and APACHE Ⅱ score, SOFA score in sepsis patients were significantly higher than those in healthy control group, and increased with the severity of sepsis. There was no statistically significant difference in CRISPLD2 level between the dead and the survival of sepsis, and the levels of PCT and CRP in death group were significantly higher. The levels of CRISPLD2 were significantly negative correlated with the levels of PCT, CRP, APACHE Ⅱ score and SOFA score (r values were -0.089,-0.431, -0.115, -0.201, respectively, allP < 0.05). It was shown by ROC curve analysis that the area under ROC curve (AUC) and 95% confidence interval (95%CI) of CRISPLD2, PCT, CRP for diagnosis of sepsis were 0.907 (0.871-0.944), 0.922 (0.886-0.958), 0.916 (0.878-0.954) respectively, allP = 0.000; when the cut-off value of CRISPLD2 > 216.0 mg/L, the sensitivity was 96.7%, and the specificity was 92.6%, which power lied between PCT and CRP. The AUC of CRISPLD2 for prognosis was significantly lower than that of PCT [0.617 (0.507-0.727) vs. 0.786 (0.668-0.903),P <0.01]; when the cut-off value of CRISPLD2 was 103.5 mg/L, the sensitivity was 100%, and the specificity was 25.6%. Conclusion CRISPLD2 is a potential biomarker in sepsis, but cannot predict the prognosis of patients with sepsis.

Objective To observe the efficacy and safety of Bushen Huoxue Prescription in the treatment of kidney deficiency and blood stasis type primary osteoporosis. Methods Totally 50 patients with kidney deficiency and blood stasis type primary osteoporosis were collected. They were given Bushen Huoxue Prescription granules twice a day, taking with water, for 12 weeks. Before and after treatment, the femoral neck, Ward's area, L1–4 bone mineral density (BMD) were measured. VAS and TCM syndrome integrals were evaluated before and 4, 8 and 12 week of treatment. The level of serum osteocalcin (OC), β-C-terminal telopeptides of type I collagen (β-CTX) and osteoprotegerin (OPG) were detected before and after treatment. Hematuria routine, liver and kidney function were under safety testing before and after treatment. Results Bushen Huoxue Prescription could significantly increase BMD of left femoral neck and Ward's triangle (P=0.001, P=0.044). L1–4 BMD increased, without statistical significance (P=0.172). The total effective rate was 60.870% (28/46) for L1–4 and left femoral neck and 58.696% (27/46) for Ward's triangle. The VAS and TCM syndrome integral decreased significantly 4 weeks treatment compared with that before the treatment (P<0.01), and the scores decreased significantly with the prolongation of treatment time (F=159.690, P<0.001; F=163.970, P<0.001). After 12 weeks, treatment, the total effective rate for TCM syndromes was 78.26% (36/46). Serum levels of OC and β-CTX showed a tendency to increase, while serum levels of OPG showed a tendency to decrease, without statistical significance (P=0.087, P=0.091, P=0.419). There was no serious adverse reaction in hematuria routine and liver and kidney function. Conclusion Bushen Huoxue Prescription has obvious clinical efficacy for kidney deficiency and blood stasis type primary osteoporosis, which can improve the patients' BMD, improve bone metabolism, relive bone pain, with high level of safety.

Objective:To understand the level of iodine nutrition in the areas with iodine deficiency and high iodine in Anyang City of Henan Province, and to provide a basis for taking targeted prevention and treatment measures and scientific adjustment of intervention strategies.Methods:In 2019, three areas with iodine deficiency (median iodine in water < 10 μg/L) and three areas with high water iodine (median iodine in water > 100 μg/L) were selected from counties (cities and districts) in Anyang City by stratified random sampling. Children aged 8-10 and pregnant women were selected in areas with high iodine and areas with iodine deficiency, respectively. Urine samples and salt samples were collected and tested, and children's thyroids were examined by B-mode ultrasound.Results:A total of 654 salt samples were collected in iodine deficiency areas, among which non-iodized salt accounted for 1.83% (12/654). A total of 628 salt samples were collected from areas with high iodine, among which non-iodized salt accounted for 6.05% (38/628). The difference in non-iodized salt rate between the two areas was statistically significant (χ 2=15.19, P < 0.05). A total of 654 urine samples were collected from children in iodine deficiency areas, with a median of 211.15 μg/L of urinary iodine, and 628 urine samples were collected from high iodine areas, with a median of 390.50 μg/L of urinary iodine. The difference was statistically significant ( U=- 18.34, P < 0.05). A total of 300 urine samples were collected from pregnant women in iodine deficiency areas, with a median of 223.95 μg/L, and 127 urine samples were collected from pregnant women in high iodine areas, with a median of 258.00 μg/L. The difference was statistically significant ( U=- 4.07, P < 0.05). The thyroid volume of 560 children in the iodine deficient areas was detected, and the swelling rate was 1.43% (8/560). The thyroid volume of 628 children in high iodine areas was detected, and the swelling rate was 2.07% (13/628). Conclusion:The iodine nutrition level of the population in the iodine deficiency areas of Anyang City is appropriate, while the iodine nutrition level of the population in the water source high iodine areas is excessive.

Objective To investigate the effects of berberine on tumor-associated macrophages (TAM)and the expression of cyclooxygenase-2 (COX-2)of intestinal polyps in Apc(Min/+) mice.Methods A total of 20 Apc(Min/+) mice,four weeks old,were equally divided into the control group and the berberine group,10 in each group.The mice of the control group drank plain water,while the mice of berberine group drank water with 0.1 % berberine.After 12 weeks,all the mice were sacrificed.The intestine and colon were isolated,and the numbers of polyps were counted.The expression of F4/80,inducible nitric oxide synthase-2 (iNOS),macrophage mannose receptor (MR)and COX-2 was detected by immunohisto-chemistry method.The relative expression of COX-2 at protein level was measured by Western blotting. The t test was performed for comparison between two independent groups.Results The total number of intestinal polyps,the number of small intestinal polyps and the number of colon polyps of the berberine group (11 .50±2.05 ,10.50±1 .77 and 1 .00±0.46,respectively)were all less than those of the control group (30.63±1 .69,28.00±2.00 and 2.63±0.74,respectively),and the differences were statistically significant (t=16.727,16.952 and 3.162,P =0.001 ,0.001 and 0.010,respectively).The percentage of F4/80 positive cells in the stroma of polyps of the berberine group ((17.40 ±4.23 )%)was less than that of the control group ((31 .24±6.34)%),and the difference was statistically significant (t =5 .327, P =0.043).The percentage of iNOS positive cells in the stroma of polyps of the berberine group ((7.43± 1 .78 )%) was higher than that of the control group ((2.72±0.68)%), and the difference was statistically significant (t=7.335 ,P =0.004).The percentage of MR positive cells in stroma of polyps of the berberine group ((19.52±1 .54)%)was less than that of the control group ((12.63±0.68)%),and the difference was statistically significant (t=5 .634,P =0.016).The percentage of COX-2 positive cells in stroma of polyps of berberine group ((3.38 ± 0.51 )%)was less than that of the control group ((7.60±0.57 )%),and the difference was statistically significant (t = 7.234,P = 0.001 ).The relative expression of COX-2 at protein level of polyps of the berberine group was lower than that of the control group. Conclusion Berberine may take the role in inhibiting the growth of intestinal polyps in Apc(Min/+) mice through interfering the differentiation of TAM in polyps and suppression the expression of COX-2.

Objective To investigate the effect of a peptide,APP17,on regulating the expression of insulin receptor substrate\|1(IRS\|1) and insulin\|like growth factor (IGF\|1R) in neurons of the hippocampus from diabetic mouse. Methods Diabetic mouse models were established by injection of streptozotion.In experimental group,these models were injected with APP17 peptide subcutaneously and their brain sections were taken after 4 weeks of survival. The immunohistochemical stainning of these sections were then performed with IRS\|1 and IGF\|1R antibody.With regard to control groups,the mouse models were only injected saline and gone through the same procedure of immunohistochemistry together with normal mice. Results IRS\|1 and IGF\|1R positive neurons were widely distributed in the hippocampus of the diabetic mice,and the cytoplasm was darkly stained.In the contrast,positive cells in the hippocampus were lightly stained in those normal mice and the APP17 peptide\|treated diabetic mice. Conclusion The expression of IRS\|1 and IGF\|1R could increase in the hippocampus of dabetic mice.The APP17 can regulate the distribution of IRS\|1 and IGF\|1R in the brain of diabetic mice and return them to normal situation.
