Objective:To explore the effectiveness and safety of focused ultrasound ablation surgery (FUAS) for abdominal wall endometriosis.Methods:From November 2019 to October 2022, a total of 34 patients with abdominal wall endometriosis who underwent FUAS were collected, and their clinical features, imaging features, intraoperative treatment and side effects after treatment were analyzed retrospectively, and the improvement of symptoms and re-intervention were followed up.Results:(1) Characteristics of clinical data: the average age of 34 patients with abdominal wall endometriosis was (32.8±3.8) years old. The largest diameter of the lesion was 48 mm, and the median lesion diameter was 24 mm. Thirty cases (88%, 30/34) had moderate to severe periodic pain in abdominal incision before FUAS. All patients were diagnosed by preoperative magnetic resonance imaging, including 19 cases (56%, 19/34) of superficial type, 8 cases (24%, 8/34) of intermediate type and 7 cases (21%, 7/34) of deep type. (2) FUAS treatment parameters: ablation was completed with average operation time of (64±18) minutes, average sonication time was (385±108) s, (103±11) W of average power, (38 819±16 309) J of average total energy, the average treatment area volume of (3.11±1.42) cm 3, and (377.79±106.34) s/h of average treatment intensity. (3) Efficiency: the pain of patients after FUAS was significantly relieved, and the pain scores of patients after 1 month, 3 months, 6 months and 1 year after FUAS were significantly decreased ( Z=-4.66, -5.13, -5.11 and -4.91, all P<0.01). One year after FUAS, the near relief and effective pain relief rate was 74% (25/34), and the clinical effective rate was 85% (29/34). Five patients recurred after one year, including 3 patients who underwent abdominal wall endometriosis lesion resection and 2 patients who received drug treatment. One month after FUAS, the size of the lesion did not change significantly compared with that before FUAS ( P>0.05), and the size of the lesion decreased significantly after FUAS at 3 months, 6 months and 1 year ( Z=-2.15, -2.67 and -3.41, all P<0.05). It has no difference in pain relief among different types ( P>0.05), but has significant difference in focus reduction among three types ( P<0.01). (4) Safety: there were 34 cases (100%, 34/34) of skin burning sensation, 19 cases (56%, 19/34) of pain in the treatment area and 2 cases (6%, 2/34) of hematuria. All patients got better after corresponding treatments. Conclusion:FUAS is safe and effective for the treatment of abdominal wall endometriosis, which has clinical application value.

Common iliac artery ureteral fistula is a rare but potentially life-threatening disease which is difficult to diagnose clinically. This paper reports a case of common iliac artery ureteral fistula. The patient was admitted to our hospital due to ureterostomy bleeding for one day. He underwent radical cystectomy and bilateral ureterostomy for bladder cancer 4 years ago, and also underwent radiotherapy and bilateral ureteral stents indwelling after the operation. Angiography revealed a left common iliac artery pseudoaneurysm, and a left common iliac artery ureteral fistula was considered. The left common iliac artery stent-graft was implanted. The patient recovered well after the operation, and there was no obvious hematuria during follow-up period of 6 months.

Objective:To retrospectively analyze the pregnancy outcomes of patients with adenomyosis requiring fertility in a single center under real world condition.Methods:From June 2015 to May 2020, 231 cases of pregnancy complicated with adenomyosis diagnosed by ultrasound with fertility requirements were treated in the Women′s and Children′s Hospital Affiliated to Qingdao University with complete clinical data. And they were divided into three groups according to the treatment of adenomyosis before pregnancy: expectation group, drug group and operation group. The relevant data before pregnancy of the three groups were analyzed, and the pregnancy outcomes of the patients were summarized. According to whether the early pregnancy was treated with medication, the patients who were naturally conceived without symptoms of threatened abortion were divided into observation group and fetus protection group, and the pregnancy outcomes of the two groups were compared.Results:(1) Compared with the expectation group, the ages of patients in the drug group and the operation group were larger [(31.5±1.8) vs (34.1±3.7) vs (36.9±3.6) years old], and the difference was statistically significant ( P<0.05). Only 9 patients (11.5%, 9/78) had clinical symptoms in the expectation group, while the patients in the drug group and the operation group had a higher proportion of dysmenorrhea and increased menstrual volume. The uterine volume of the drug group and the operation group were larger than that of the expectation group [(151±46) vs (166±27) vs (97±18) cm 3], the difference was statistically significant ( P<0.05). 78.6% (33/42) of the operation group were focal adenomyosis. The proportion of natural pregnancy in the expectation group was 97.4% (76/78), and in vitro fertilization and embryo transfer was mainly used in the drug group and the operation group. (2) The abortion rates of the three groups were 48.7% (26/111), 4/17, 67.5% (27/78) respectively. Compared with the drug group and the operation group, the preterm birth rate was lower [55.9% (33/111) vs 11/17 vs 12.5% (5/78)] and the natural delivery rate was higher [44.1% (26/111) vs 4/17 vs 67.5% (27/78)] in the expectation group. (3) There were 89 cases of spontaneous pregnancy without threatened abortion symptoms, including 31 cases in the observation group and 58 cases in the fetus protection group. Compared with the observation group, the abortion rate of patients in the fetus protection group was lower [41.9% (13/31) vs 34.5% (20/58)], and the difference was statistically significant ( P<0.05). Conclusions:Patients with adenomyosis who have fertility requirements should be comprehensively evaluated and individualized treatment plans should be given. Pregnancy patients with adenomyosis have a high rate of miscarriage, and they should be included in the management of high-risk pregnant women. Active fetal protection treatment during early pregnancy might improve pregnancy outcomes.

ObjectiveTo investigate the protective effect of Zuoguiwan against ⁶⁰Co-γ ray-induced premature aging of rats based on the phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway. MethodSixty sexually mature female SD rats were irradiated with ⁶⁰Co-γ rays （6.0 Gy， LD₄₀） for 24 h at one time. Then they were randomized into model group， Bujiale group （0.18 g·kg^-1·d^-1）， Bujiale （0.09 g·kg^-1·d^-1） + high-dose Zuoguiwan group （23.625 g·kg^-1·d^-1）， high-dose Zuoguiwan group （23.625 g·kg^-1·d^-1）， medium-dose Zuoguiwan group （9.45 g·kg^-1·d^-1）， and low-dose Zuoguiwan group （4.725 g·kg^-1·d^-1）. The administration （once a day） lasted 21 days. Serum indexes ［follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂）］ of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and morphological changes of ovarian tissues were observed based on hematoxylin and eosin （HE） staining. The apoptosis rate of granulosa cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） and the protein expression of phosphorylated （p）-PI3K， p-Akt， p-mTOR， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in ovarian tissues by Western blot. ResultCompared with normal group， model group demonstrated increase in serum FSH （P<0.01）， decrease in E₂ （P<0.05）， and reduction of follicles and luteum in early ovary （P<0.01）. Moreover， the elevation of apoptosis rate of granulosa cells （P<0.01）， down-regulation of p-PI3K， p-Akt， p-mTOR， and Bcl-2 in ovarian tissue， and increase in expression of Bax were also observed in the model group as compared with the normal group （P<0.01）. In comparison with the model group， the administration groups showed rise of the number of early ovarian follicles， decrease in the apoptosis rate of granulosa cells， increase in the expression of p-PI3K， p-Akt， p-mTOR， and Bcl-2， and down-regulation of Bax， particularly the Bujiale + high-dose Zuoguiwan group（P<0.05，P<0.01）. ConclusionZuoguiwan protects radiation-damaged ovary by activating the expression of PI3K/Akt/mTOR protein in ovarian tissue， increasing Bcl-2， and inhibiting the expression of Bax.

Background::Urticaria is a common skin disease characterized by episodes of wheals, and it has a negative effect on patients’ quality of life. Large-scale population-based epidemiological studies of urticaria are scarce in China. The aim of this survey was to determine the prevalence, clinical forms, and risk factors of urticaria in the Chinese population.Methods::This survey was conducted in 35 cities from 31 provinces, autonomous regions, and municipalities of China. Two to three communities in each city were selected in this investigation. Participants completed questionnaires and received dermatological examinations. We analyzed the prevalence, clinical forms, and risk factors of urticaria.Results::In total, 44,875 questionnaires were distributed and 41,041 valid questionnaires were collected (17,563 male and 23,478 female participants). The lifetime prevalence of urticaria was 7.30%, with 8.26% in female and 6.34% in male individuals ( P < 0.05). The point prevalence of urticaria was 0.75%, with 0.79% in female and 0.71% in male individuals ( P < 0.05). Concomitant angioedema was found in 6.16% of patients. Adults had a higher prevalence of urticaria than adolescents and children. Living in urban areas, exposure to pollutants, an anxious or depressed psychological status, a personal and family history of allergy, thyroid diseases, and Helicobacter pylori infection were associated with a higher prevalence of urticaria. Smoking was correlated with a reduced risk of urticaria. Conclusion::This study demonstrated that the lifetime prevalence of urticaria was 7.30% and the point prevalence was 0.75% in the Chinese population; women had a higher prevalence of urticaria than men. Various factors were correlated with urticaria.

Objective:To investigate the clinical characteristics of Guillain-Barré syndrome (GBS) combined with hyponatremia in Southern China and its risk factors for prognosis.Methods:The retrospective cohort study involved patients who met the diagnostic criteria of GBS from 18 upper first-class hospitals of 6 provinces/cities in southern China (south of Huaihe River) from January 1, 2013 to September 30, 2016. The clinical data of these patients were collected. According to serum sodium levels, they were divided into hyponatremia group (serum sodium concentration<135 mmol/L) and normal serum sodium group (serum sodium concentrations≥135 mmol/L). Based on Medical Research Coucil sum scores at nadir, these patients were divided into mild GBS group (>40), moderate GBS group (30-40), and severe GBS group (<30). Furthermore, according to the Hughes GBS disability scale (H-GBS-DS) scores at discharge, these GBS patients with hyponatremia were divided into favorable prognosis group (H-GBS-DS<3) and poor prognosis group (H-GBS-DS≥3). The incidence of hyponatremia in patients from the mild GBS group, moderate GBS group, and severe GBS group were compared. Multivariate Logistic regression analysis was performed to determine the clinical risk factors for hyponatremia in GBS patients. The clinical data of hyponatremia patients from favorable prognosis group and poor prognosis group were compared; multivariate Logistic regression analysis was used to determine the risk factors for poor prognosis in GBS patients with hyponatremia.Results:(1) Among the 570 patients, 354 had mild GBS, 94 had moderate GBS, and 122 had severe GBS; 134 GBS patients were combined with hyponatremia, 436 GBS patients had normal serum sodium. The hyponatremia incidence in mild, moderate and severe GBS groups increased successively, ( P<0.05). Multivariate Logistic regression analysis showed that facial paralysis ( OR=1.979, 95%CI: 1.172-3.342, P=0.011), respiratory muscle paralysis ( OR=3.218, 95%CI: 1.611-6.428, P=0.001), secondary pulmonary infection ( OR=4.822, 95%CI: 2.835-8.201, P=0.000), severe GBS ( OR=2.611, 95%CI: 1.444-4.721, P=0.001) and length of hospital stay ( OR=1.029, 95%CI: 1.009-1.050, P=0.004) were risk factors for hyponatremia in GBS patients. (2) Among 134 GBS patients with hyponatremia, 80 had poor prognosis and 54 had favorable prognosis. As compared with the favorable group, the poor prognosis group had significantly lower proportion of patients with extraocular muscle paralysis, statistically higher proportions of patients with respiratory muscle paralysis and secondary pulmonary infection, significantly different severities of GBS, signficantly higher proportion of patients accepted intravenous immunoglobulin (IVIG) and hormone treatments, statistically longer length of hospital stay ( P<0.05). Respiratory muscle paralysis ( OR=25.590, 95%CI: 9.433-69.423, P=0.000), moderate GBS ( OR=17.030, 95%CI: 8.441-34.361, P=0.000), and severe GBS ( OR=51.042, 95%CI: 24.596-105.926, P=0.000) were independent risk factors for poor short-term prognosis of GBS patients with hyponatremia. Conclusions:Severe GBS patients with facial paralysis, respiratory muscle palsy, secondary pulmonary infection, and long hospital stay trend to have hyponatremia. Hyponatremia patients with respiratory muscle paralysis and moderate/severe GBS have poor short-term prognosis.

Objective:To observe the adverse reactions of Diphtheria, Tetanus, Acellular Pertussis and Haemophilus Influenzae Type b Combined Vaccine conjugate vaccine at the anterolateral thigh muscle, upper arm deltoid muscle and upper gluteal region.Methods:A total of 12 241 infants who were voluntarily vaccinated DTaP-Hib from April 2015 to April 2019 in Beijing were selected for the study. DTaP-Hib vaccine is recommended for 3, 4, 5 months of age for basic immunization and 18 to 24 months of age to strengthen immunization. Subjects were divided into the groups of lateral thigh muscle, the upper arm deltoid and upper gluteal region according to the actual inoculation sites. Adverse reactions were collected within 30 minutes and 7 days after each does of vaccination at different sites and compared between three groups. The incidence of adverse reactions at the three different inoculation sites was compared by Chi-square test.Results:A total of 12 241 infants and toddlers received combined DTaP-Hib and 35 027 doses of DTaP-Hib were investigated. The number and of lateral thigh muscles, upper arm deltoids and gluteal muscles were 3 461 infants and 11 129 doses, 2 659 infants and 7 957 doses, 6 121 infants and 15 941 doses respectively. A total of 2 489 adverse reactions occurred. The incidence of adverse reactions was 7.11%. The incidence of adverse reactions in deltoid muscle of upper arm was 9.69%（771 doses）, which was higher than that in gluteal muscle (7.58%, 1 211 doses) and anterolateral muscle of thigh (4.56%, 507 doses). The incidence of mild, moderate and severe adverse reactions in the upper arm deltoid group were higher than those in the other two groups. The incidence rates were 4.85% (386 doses), 3.77% (300 doses) and 1.07% (85 doses) respectively. The differences between groups were statistically significant（ P<0.001）. The total adverse reactions of the three doses of basic immunization and the fourth dose of enhanced immunization had the same trend in different parts. The incidence of adverse reactions was in the order of the upper arm deltoid injection, upper gluteal injection and lateral thigh muscle injection from high to low. The differences were statistically significant ( P<0.001). Conclusion:The incidence of adverse reactions of DTaP-Hib vaccination in three different sites was low, which confirmed that the DTaP-Hib vaccination got expected safety regardless of the sites of inoculation. The lateral femoral muscle group had the lowest incidence of adverse reactions, hence it should be preferred as the inoculation site of DTaP-Hib vaccination.

OBJECTIVE： To explore the method for the development and implementation of drug abuse monitoring in medical institutions， and to provide reference for drug abuse monitoring in medical institutions. METHODS： Our hospital （the affiliated hospital of Binzhou medical college） had established the corresponding drug abuse monitoring mode from the two aspects of real-time monitoring and retrospective analysis， supplemented by relevant management measures， defined the content of drug abuse monitoring in medical institutions， and finally evaluated the implementation effect through the effective reporting quantity of drug abuse information， etc. RESULTS & CONCLUSIONS： The main contents of drug abuse monitoring in our hospital included the establishment of drug abuse monitoring management group， the improvement of drug abuse monitoring system and the sorting out of drug monitoring catalogue； the real-time drug abuse monitoring mode was established through timely reporting drug abuse information by medical， nursing and pharmaceutical personnel in daily diagnosis and treatment activities； at the same time， the retrospective analysis model of drug abuse was established by analyzing the relevant drug use data regularly through the hospital information system， paying attention to the key groups of key departments， and mining drug abuse information； a series of auxiliary management measures were taken， such as strengthening training and publicity， and establishing reward and punishment mechanism. Since the monitoring work was started in 2016， the effective number of drug abuse information reported in 2016-2018 was 38， 126 and 237 respectively， and through the monitoring， it was found that the elderly women over 60 years old （69.83％） were abusing in iatrogenic sedative hypnotic drugs. The development of drug abuse monitoring in hospital can collect drug abuse status， behavior characteristics and relevant information timely and effectively， analyze local drug abuse trends， find drug abuse risks， and provide basis for drug control of narcotics and psychotropic substances supervision.

OBJECTIVETo explore the impact of electroacupuncture (EA) on the protein expression of adenosine receptors in the heart of the rats with myocardial ischemia (MI).

METHODSThirty healthy male SD rats were divided randomly into a control group (=6), a model group (=12) and an EA group (=12). We ligated the left anterior descending artery (LAD) for MI model in the model group and EA group, and exposed the heart after opening the chest without ligation in the control group. EA, 2 Hz /15 Hz and 1.5-2 mA, was applied at bilateral"Neiguan"(PC 6) in the EA group for 20 min, once a day for continuous 5 days. No intervention except grabbing and fixation was used in the control group and model group. We applied 2% TTC staining to observe the infarct size of myocardium, colorimetry to analyze serum lactic dehydrogenase (LDH), creatine kinase (CK), creatine kinase isoenzyme (CK-MB), radio-immunity assessment to detect cardiac troponin T (cTnT), Western blot to evaluate the adenosine A1 receptor (A1AR), A2aAR, A2bAR and A3AR.

RESULTSAfter treatment, myocardial infarction of (27.56±3.24)% was obvious in the model group; the myocardial infarction in the EA group was (21.04±3.61)%, with statistical significance (<0.05). The expressions of serum LDH, CK, CK-MB and cTnT levels in the model group increased compared with those in the control group (all<0.01), and the expressions of LDH, CK, CK-MB and cTnT levels in the EA group decreased compared with those in the model group (<0.05，<0.01). The A1AR expression in the model group was not different from that in the control group (>0.05), and A2aAR、A2bAR、A3AR expressions decreased (<0.05,<0.01). A2aAR and A2bAR expressions in the EA group increased compared with those in the model group (both<0.01), and there was no statistical significance between A1AR and A3AR expressions (both>0.05). .

CONCLUSIONEA may achieve cardioprotective effect by regulating the expressions of A2aAR and A2bAR in myocardial tissue, which induce the corresponding signal cascade for reducing myocardial infarction area.
