Chronic gastritis has varied clinical symptoms and prolonged course,and seriously affects the life quality of patients.Studies have shown that mood disorders might affect the pathogenesis of chronic gastritis.Aims:To investigate the incidence of anxiety and depression and its relationship with digestive symptoms,Helicobacter pylori (Hp) infection,degree and activity of inflammation in patients with chronic gastritis.Methods:A total of 235 patients with chronic non-atrophic gastritis were enrolled.Anxiety,depression,gastrointestinal symptoms,gastric mucosal inflammation and activity were evaluated,and infection of Hp was detected.Results:In the 235 patients,144 (61.3%)were accompanied by anxiety and/or depression:108 patients (46.0%)were accompanied by anxiety,129 patients (54.9%) were accompanied by depression,93 patients (39.6%)were accompanied by anxiety and depression.Incidence of abdominal pain,abdominal distention and early satiety,scores of digestive symptoms,positive rate of Hp infection and incidence of severe inflammation in patients accompanied by anxiety and/or depression were significantly higher than those in patients without anxiety and depression (P<0.05 ),but no significant difference in inflammation activity was seen between the two groups (P>0.05).Conclusions:Incidence of anxiety and depression in patients with chronic gastritis is high.Anxiety and depression are associated with abdominal pain,abdominal distention and early satiety,and can affect the inflammatory degree of gastric mucosa.Patients with anxiety and depression are susceptible to Hp infection.

Clinical characteristics,including primary and secondary sexual characteristics,basal endocrine profiles,and imaging results were reviewed.Follow-up data were recorded.16 patients had normal karyotypes,manifest amastia,infantile genitalia,amenorrhea,and delayed epiphyseal fusion at the knee and wrist joints.Serum gonadotropic hormone levels were significantly below normal values.15 patients underwent a gonadotropin-releasing hormone (GnRH) stimulation test and 6 patients had a prolonged GnRH stimulation test.16 patients underwent pituitary or brain magnetic resonance imaging (MRI),which showed small pituitaries in three patients,wing tips of suspicious nodules in 2 patients,an empty sella turcica in 1 patient,and a missing right olfactory bulb and tract in 1 patient.1 patient had no detectable uterus or accessory organs,while the other patients had primordial uteri.1 patient was diagnosed as a case of severe osteoporosis.1 patient suffered from pituitary stalk interruption syndrome.An artificial menstrual cycle due to hormone replacement therapy was not sustained after discontinuation of hormone therapy.As disease severity and the date of initiating hormone replacement varied,the results of treatment were quite different.For patients of reproductive age,it was rare to see a reversal of idiopathic hypogonadotropic hypogonadism after discontinuation of hormone therapy.

Objective? To explore the effects of audio-visual comprehensive training on cognitive impairment among breast cancer patients with chemotherapy. Methods? From July 2017 to October 2018, we selected 80 inpatients with chemotherapy in breast surgery as subjects by convenience sampling. All of the patients were divided into control group (n=40) and experimental group (n=40) with the lot-drawing method. Patients of two groups were all treated with the routine treatment and nursing of breast surgery, while experimental group also received audio-visual comprehensive training. The intervention effects were assessed with the Rivermead Behavioral Memory Test Second Edition (RBMT-Ⅱ). Results? After intervention, the scores of names, belongings, data, faces, delayed story, orientation, delayed route, messages and the total score of experimental group were higher than those before intervention; the score of immediate route was lower than that before intervention;the differences were all statistically significant (P＜ 0.05). After intervention, the total score and sub-test scores of RBMT-Ⅱof control group were lower than those before intervention with statistical differences (P＜ 0.05). After intervention, the scores of RBMT-Ⅱ of experimental group were higher than those of control group except for orientation and data with statistical differences (P＜ 0.05). Conclusions? Audio-visual comprehensive training can effectively improve cognitive impairment among breast cancer patients with chemotherapy which is simple and feasible, and can be promoted and applied.

Objective To improve the positivity for insulinoma localization by imaging before surgery.Methods The clinical data of 119 patients with insulinoma who had been admitted to Chinese PLA General Hospital from January 1985 to April 2008 were retrospectively reviewed. Results One hundred patients with hypoglycemia who had been operated and most of them (98/100) diagnosed as insulinoma pathologically were analyzed. They had undergone various methods of localization by imaging before surgery. The positive rates for tumor localization were 22.9% (17/74) by uhrasonography (US), 55.2% (48/87) by CT, 58.8% (10/17) by MRI,76.6% (49/64) by digital subtraction angiography (DSA) ,93.3% (42/45) by endtoscopic ultrasonography (EUS)and 94.7% (18/19) by uhrasonic contrast (UC). While the rates of accuracy for tumor localization were 88.2% (15/17) by US ,87.5% (42/48) by CT, 90.0% (9/10) by MR1,100.0% (49/49) by DSA, 85.7% (36/42) by EUS and 83.3% (15/18) by UC. The rates of accuracy in patients with one,two and three positive images were 88.9% (24/27), 96. 9% (32/33) and 94. 7% (18/19), respectively. The positive rates in patients with combination of two images were 47.6% (30/63) by CT and US ,75.5% (40/53) by CT and DSA ,89.2% (33/37)by CT and EUS,90.0% (27/30) by EUS and DSA ,78.6% (11/14) by DSA and UC ,92.3% (12/13) by CT and UC, and 90.9% (10/1 i) hy EUS and UC, respectively. Conclusion The positive rates and accuracy of localization for insulinoma were increased by combining at least two images, and the combinations of any two of four images including CT, DSA, EUS and UC are suggested. While considering both the cost and effect, we recommend CT combined either with EUS or UC.

Objective:To evaluate and compare the inpatient medical services of secondary public and private general hospitals by using disease risk adjustment model, and to explore the application of disease risk adjustment model in medical service evaluation of different ownership hospitals.Methods:Based on 1 032 865 front pages of medical records in Chengdu in 2017 and 2018, a regression model with mortality, average length of stay, total hospitalization expenses, medical service fees, drug costs and surgical consumables costs as dependent variables and related influencing factors as independent variables was established by using disease management intelligent analytic and evaluation system. The risk adjusted case mix index(ACMI) was calculated. The mortality, average length of stay, hospitalization expenses and other indicators were predicted. The ratio of observed value to expected value(O/E value) of each index in public and private secondary general hospitals was obtained and compared.Results:The ACMI value of secondary public general hospital was 4.63, slightly higher than that of private hospitals(4.55). The technical difficulty and resource consumption of the public hospitals were slightly higher than that of the private hospitals.From the O/E value, the management of disease mortality, medical service fees and inpatient drug costs of secondary public hospitals was generally good, and the O/E values of hospitalization expenses of each secondary private general hospital were quite different, and there was a possibility that the costs were unreasonable. The O/E value of surgical consumables cost in secondary public general hospital was 1.54, and there was room for improvement in cost management.Conclusions:The disease risk adjustment model fully considers the characteristics of different types and severity of diseases in different institutions, which can not be simply compared. Based on individual cases, it realizes the comparability of different ownership hospitals, and provides a new means for the evaluation of medical service ability and quality.

Objective: To analyze the clinical characteristics of hepatic flare and evaluate efficacy of antiviral treatment in pregnant women with chronic HBV infection. Methods: A single-center, open-label, prospective study was conducted, and pregnant women with chronic HBV infection were enrolled. Liver function, HBV serum markers and HBV DNA of pregnant women with chronic HBV infection were reviewed during every 4 to 12 weeks of gestation period. The proportion and clinical characteristics of hepatitis flare during pregnancy were observed. Logistic regression analysis was used to predict hepatic flare in pregnant women with chronic HBV infection. Antiviral therapy with telbivudine (LdT) or tenofovir dipivoxil (TDF) was used to treat hepatic flare during pregnancy. Sequential entecavir (ETV) or TDF was applied after the delivery. Treatment course and drug withdrawal in pregnant women with hepatic flare was the same as those of the general patients with chronic hepatitis B. Liver function, HBV serum markers and HBV DNA were measured in pregnant women with hepatic flare at different time points (4, 12, 24 and 52 weeks). A t-test was used to compare the hepatic flare in pregnant women with and without hepatitis group. HBsAg and HBeAg were used to quantify the receiver operating characteristic (ROC) curve of pregnant women with hepatic flare during pregnancy. Area under the ROC curve was used to calculate the optimal cut-off value corresponding to the maximum sensitivity and specificity of the ROC curve. Results: Of the 220 pregnant women with chronic HBV infection, 55 (25%) had hepatitis flare during pregnancy and received antiviral treatment. Among the 55 women with hepatic flare during gestation, 47 (85.46%) had hepatic flare in the mid-second trimester (12-24 weeks); average peak value of alanine aminotransferase (ALT) was 220.62 U/L, and the average peak value of ALT in 32 cases (58.18%) of pregnant women with hepatic flare was between 2–5 × ULN. HBsAg and HBeAg quantification were significantly lower in pregnant women with hepatic flare during pregnancy than with non-hepatitis (t = -3.745, P < 0.001; t = -2.186, P = 0.030). Multivariate logistic regression analysis showed that pregnant women with HBeAg < 3.065 log10 s/co were 7.576 times more likely to have hepatic flare during pregnancy (95% confidence interval: 3.779-15.190). ALT normalization, undetectable HBV DNA levels, HBeAg loss and HBeAg seroconversion in 55 pregnant women with hepatic flare at 52-week treatment was 100% (55/55), 74.55% (41/55), 47.27% (26/55) and 41.82% (23/55), respectively. HBsAg quantification at 52 weeks was significantly lower than baseline HBsAg quantification (3.32 + 0.37) log₁₀ IU/ml and (3.95 + 0.40) log₁₀ IU/ml; t = 8.465, P < 0.001). Conclusion Hepatic flare often occurs in the second trimester of pregnancy in pregnant women with chronic HBV infection and baseline HBeAg quantification is an independent predictor of hepatic flare. HBeAg seroconversion rate increased at 52 weeks after antiviral therapy.

Objective To observe the effects of line-needling method combined with distal acupoint selection on the temperature of waist and lower limb circulation in patients with Taiyang meridian type lumbar disc herniation(LDH)using infrared thermal imaging.Methods A total of 54 subjects were included,including 34 patients with Taiyang meridian type LDH and 20 healthy subjects.The patients were treated with lumbar line-needling method and distal acupuncture,leaving the needle for 30 min,once every other day,3 times a week for 4 weeks.Healthy subjects were not treated.The infrared thermal imaging of the waist and lower limbs of healthy subjects and patients before and after treatment was collected,and 4 areas(affected lumbar muscle area,thigh posterior side,popliteal cavity and calf posterior side)through which the meridians ran were selected to measure and record the body surface temperature.The difference of circulating temperature between healthy subjects and patients before and after treatment was compared and analyzed.The simplified McGill Pain Scale(SF-MPQ)score and Oswestry Disability Index(ODI)score were compared before and after treatment,and the clinical efficacy was evaluated.Results LDH patients with Taiyang meridian type had abnormal temperature along the meridian in the waist and lower limbs.Compared with healthy subjects,abnormal low-temperature areas could be seen in the meridian areas of the waist and lower limbs(P<0.05).After treatment,the temperature in the meridian area increased,and the SF-MPQ score and ODI score significantly decreased(P<0.05),with a total effective rate of 97.06%(33/34).Conclusion The combination of line-needling method and distal acupoint selection can significantly improve the clinical symptoms of LDH patients with Taiyang meridian type,and has a significant adjustment effect on the changes of lumbar and lower limb meridian temperature.

Background:Family history of gastric cancer is an important indicator of genetic susceptibility.Studies have shown that the family history of gastric cancer might have impact on Helicobacter pylori (Hp) infection and clinicopathological manifestations in patients with chronic gastritis.Aims:To investigate the correlation of family history of gastric cancer with Hp infection and pathological changes of gastric mucosa in patients with chronic gastritis.Methods:A total of 312 patients with chronic gastritis were enrolled to study the relationship between family history of gastric cancer and Hp infection,degree of gastric mucosal inflammation,activity of inflammation,and degree of atrophy and intestinal metaplasia.Results:In the 312 patients with chronic gastritis,165 (52.9％) had family history of gastric cancer,and 147 (47.1％) without family history of gastric cancer.Incidence of Hp infection,degree of gastric mucosal atrophy and intestinal metaplasia in patients with family history of gastric cancer were significantly higher than those without (P ＜ 0.05),but no significant differences in degree and activity of inflammation were found between the two groups (P ＞ 0.05).Conclusions:The incidence of Hp infection is higher in chronic gastritis patients with family history of gastric cancer.Family history of gastric cancer may aggravate gastric mucosal atrophy and intestinal metaplasia.
