Background: Patients with dyspepsia are the major group of outpatient department of gastroenterology. Dyspeptic symptoms are closely related to anxiety and/or depression. However, the relationship of anxiety and/or depression to dyspeptic symptoms in outpatients undergoing gastroscopy is still unclear. Aims: To investigate the incidence of anxiety and/or depression in outpatients undergoing gastroscopy and its correlation with the severity of dyspepsia. Methods: Outpatients underwent gastroscopy from November 2021 to December 2021 at West China Hospital, Sichuan University were recruited. Generalized anxiety disorder-7 (GAD-7), patient health questionnaire-9 (PHQ-9) were used to evaluate anxiety and depression, respectively. Rome diagnostic questionnaire for functional gastrointestinal disorders, severity of dyspepsia assessment questionnaire, visceral sensitivity index were used to evaluate dyspepsia. The correlation of anxiety and/or depression with dyspepsia was analyzed. Results: A total of 458 questionnaires were collected effectively, including 146 (31.9%) patients with anxiety and/or depression. Compared with the non-anxiety and depression group, the number of gastroscopy in the anxiety and/or depression group was significantly higher (P<0.05). Compared with the non-anxiety and depression group, the incidences of extremely mild/mild dyspepsia, moderate/severe epigastric fullness, postprandial fullness, epigastric pain and belching were significantly increased in the anxiety and/or depression group (P<0.05). Anxiety and/or depression was significantly correlated with the severity of dyspepsia and visceral sensitivity (r=0.421, r=0.143; P< 0.05). Conclusions: Anxiety and/or depression is common in outpatients undergoing gastroscopy; anxiety and/or depression may lead to repeated endoscopic examinations; anxiety and/or depression is significantly correlated with dyspepsia and visceral sensitivity.

Objective To investigate the effect of acupuncture decompression operation on the quality of life of patients with mild to moderate essential hypertension. Methods 74 cases of mild to moderate essential hypertension were divided into experimental group and control group by random number table, 4 cases were lost. Finally, a total of 70 patients were included in the data analysis. In the control group, 35 cases were given routine drug taking and health guidance, the experimental group of 35 patients increase the treatment of acupuncture decompression operation points on this basis. The two groups of patients were measured with blood pressure before and after intervention, and World Health Organization Quality of Life (WHOQOL-BREF) was used to evaluate the quality of life, and the data were analyzed. Results The scores of physiological and psychological fields in the experimental group were (15.23 ± 2.66) points and (16.68 ± 2.23) points while the control group were (13.98 ± 2.18) points, (15.25 ± 2.52) points, the difference was statistically significant (t=2.305, 2.522, P<0.05). The experimental group of social relations, environmental score were respectively (1.37 ± 2.24) points, (14.16 ± 1.24) points, while the control group were (13.29 ± 2.30) points, (13.56 ± 1.36) points, 2 groups were not statistically significant (t=0.770, 3.063, P > 0.05). The experimental group systolic blood pressure, diastolic blood pressure were (121.43 ± 6.43) mmHg (1 mmHg=0.133 kPa), (71.74 ± 3.88) mmHg, compared with the control group were (128.34±5.72) mmHg, (76.06±4.43) mmHg. The difference was statistically significant (t=-4.753,-4.210, P<0.05). Conclusions acupuncture decompression operation can improve blood pressure in young and middle-aged patients with hypertension, improve the quality of life.

Objective To investigate the correlation between atypical respiratory pathogens infection and serum total IgE levels . Methods Serum IgM level was detected in 1 913 blood samples of children with atypical respiratory infection by using indirect im‐munofluorescence assay ,including mycoplasma pneumonia(MP) ,legionella pneumophila (LP) ,rickettsia Q(QFR) ,chlamydia pneu‐monia(CPn) ,adenovirus (Adv) ,respiratory syncytial virus (RSV) ,influenza A virus (IAv) ,influenza B virus (IBv) and parainflu‐enza virus (PIV)1/2/3 .The serum total IgE level was detected by immune scatter turbidimetry .Software SPSS 17 .0 was used in data statistical analysis .Results A total of 991 out of 1 913 samples of respiratory inflected children exhibited positive(positive group) ,while 922 exhibited negative(negative group) in indirect immunofluorescence assay .650 out of the 991 positive samples (65 .59% ) contained MP infection and the combination of MP infection and other virus infections .The serum total IgE level in posi‐tive group was significantly higher than that of the negative group ,and the serum total IgE level in samples with MP infection was higher than that in samples with IBv infection ,Adv infection ,and RSV infection .In the samples in which serum total IgE level was higher than the clinical reference range (100 kU/mL) ,the infection rate of MP infection alone was 31 .29% ,which was evidently higher than that in samples of low IgE level(< 100 kU/mL ,21 .30% ) .On the other hand ,the infection rate of RSV alone was 1 .88% and the infection rate of Adv alone was 3 .13% ,which were both evidently lower than those in samples with normal serum total IgE level(both 6 .53% ) .Conclusion MP is the most common pathogen in children with atypical respiratory pathogen infec‐tion ,and can lead to higher serum total IgE levels .

Objective To establish a stable animal model for sequentially dynamic and direct monitoring of the skin wound infection. Methods The mice with full-thickness skin incisions were replicated. After immediate subcutaneous suture,the mice were randomly divided into four groups,ie,Group A was inoculated with 50 μl sterile PBS solution),Groups B,C and D were inoculated with 50 μl suspension containing 1 × 106,1 × 108 and 1 × 1010 colony forming unit (CFU)/ml bioluminescent methicillin-resistant staphylococcus aureus (MRSA) respectively.Then,the diet behavior of each group was observed and the mean weight and mortality of each group were also recorded at different time points.The bioluminescent intensity of fluoresce in the wounds was recorded at different time points by using the charge-coupled device (CCD) based imaging system.Local wound tissues were incised at 24 hours after inoculation for HE staining so as to observe wound inflammatory reaction in each group.Wound healing time of each group was also recorded. Results ( 1 ) Average weight:Groups A and B showed unobvious changes in weight; Group C lightened until day 3 after inoculation and then recovered gradually to the preinoculation level at day 14; Group D lightened gradually until death.(2)Mortality:Groups A and B had no death; Group C had 10％ deaths at day 14; Group D had 100％ deaths.(3) Bioluminescent intensity of wounds:Groups A and B showed a gradual weakened luminescence since the day of inoculation and had almost complete disappearance at days 5 and 7 respectively; there was no sign of obvious increase or decrease in Group C from the day of inoculation till day 14 ; Group D had a gradual increase since the day of inoculation and the luminous area expanded until the death.(4) HE staining at 24 hours after inoculation:all the four groups showed inflammatory cell infiltration,especially in Groups C and D.(5) Wound healing time:wound healed at days 5 and 7 after inoculation in Groups A and B; the wounds showed no healing even at day 14 in the Group C,but the wounds length and area did not show obvious enlargement or diminishment ; the wounds extended gradually until the death in the Group D,since the day of inoculation. Conclusions The inoculation of 50 μl suspension with 1 × 108 CFU/ml bioluminescent MRSA to full-thickness skin incision rats allows direct,real-time dynamic and continuous detection of the occurrence and development of the wound infections.The infection model is easy to make and has stability and high repeatability.

OBJECTIVETo study the relationship between neuropeptide Y (NPY) and diabetes by examining the content and distribution of NPY and its mRNA expression in the hypothalamus and pancreas of STZ-diabetic rats.

METHODSThirty Wistar rats were randomly divided into 3 groups (diabetic group, diabetic insulin treatment group, and control group). After feeding for 24 weeks, the rats were sacrificed. The expression of NPY in the hypothalamus and pancreas was detected with immunohistochemistry and in situ hybridization.

RESULTS(1) The hypothalamic content of NPY and its mRNA were significantly increased in STZ-diabetic rats in comparison with normal controls. Increased expression of NPY mRNA was found only in the arcuate nucleus and not in the paraventricular nucleus in diabetic rats, suggesting that NPY was produced in the arcuate nucleus. (2) The hypothalamic content of NPY and its mRNA in STZ-diabetic rats were visibly reduced after insulin treatment compared with that in untreated diabetic rats. This supports the hypothesis that insulin deficiency in the brain may be responsible for increased hypothalamic NPY gene expression in diabetic rats. (3) The increase of hypothalamic NPY in STZ diabetic rats associated with hyperphagia and polydipsia could be reversed by insulin replacement, suggesting that increased hypothalamic NPY contributes to the pathophysiological progress of the diabetic state. (4) The present study demonstrated for the first time that the content of NPY and its mRNA in the pancreas was increased in STZ-diabetic rats, and that the distribution of NPY-positive cell in islets was changed from the periphery to the whole islet. The content and distribution of NPY and its mRNA in islets were not changed by insulin treatment.

CONCLUSIONIncreased NPY in the hypothalamus results in hypophagia and polydipsia, while the implication of increased NPY in the pancreas of diabetic rats is not clear.

ObjectiveTo evaluate the effect of laparoscopic cholecystectomy (LC) combined with intraoperative cholangiography (IOC) and intraoperative endoscopic sphincterotomy (IOEST) for the diagnosis and treatment of choledocolithiasis. Methods Statistical analysis was carried out for 106 patients with cholecystocholedocolithiasis diagnosed and treated by LC-IOC-IOEST. Results Sixty-four (60.4%, 64/106 ) patients with preoperative diagnosis of simple gall stone were found with complicated choledocholithisis; LC-IOC -IOEST was successfully performed in 99(93.4%, 99/106) cases. Six cases (6.1%) suffered from mild postoperative acute pancreatitis. Duodenal perforation, bile leakage, peumothorax (0.9%) developed in one each. Duodenal adenocarcinoma was overlooked in one case, and 2 cases (1.8%) suffered from gastric paralysis. Conclusion LC combined with IOC and IOEST was a safe, effective approach to the diagnosis and minimally invasive treatment of choledocholithiasis.
