Objective: To explore therapeutic effect of in-hospital intravenous alprostadil injection on patients with acute myocardial infarction (AMI) complicated diabetic nephropathy (DN) undergoing percutaneous coronary intervention (PCI), and evaluate their long-term prognosis.Methods: A total of 80 AMI + DN patients undergoing PCI were selected from our hospital.They were randomly divided into alprostadil group (n=40) and routine treatment group (n=40).Renal function after PCI, cardiac function during hospitalization, serum creatinine (Scr) level on 72h after PCI and incidence of major adverse cardiovascular events (MACE) within one-year follow-up were compared between two groups.Results: Compared with routine treatment group on 72h after PCI, there was significant reduction in Scr level [(126.92±35.28) μmol/L vs.(104.32±22.91) μmol/L], and significant rise in estimated glomerular filtration rate [eGFR, (55.23±31.48) ml·min-1·1.73m-2 vs.(62.14±36.23) ml·min-1·1.73m-2] in alprostadil group, P<0.05 both.Postoperative one-year follow-up indicated that there were no significant difference in incidence rate of MACE and percentage of kidney replacement therapy between two groups, P>0.05 all.Conclusion: Intravenous alprostadil injection based on routine treatment possesses significant therapeutic effect on renal function in AMI + DN patients after PCI, and it's safe

Objective To explore the method of intervening measure applied at dynamic state during ultrasonic scaling treatments and may control the aerosols and spatters in dental department so that we may provide safe clinical environment for dental personnel and patients. Methods 40 patients received ultrasonic scaling treatments were divided into experiment and control group. The experimental group received measures by the ozone air disinfector at the beginning of ultrasonic scaling treatments (the ozone air disinfector worked 5 minutes) and the control group was not received the device treatment.. Air samples were collected at different appointed period. Results A Mann-Whitney test was conducted to determine significant difference between the ultrasonic scaling treatments with the ozone air disinfector and the ultrasonic scaling treatments without the device at different appointed time. The general bacterial population in the air were lower in experimental group than in control group (P < 0.01). Conclusions The ozone air disinfector applied at dynamic state during ultrasonic scaling treatments may control the quantities of colony-forming units of aerosols and spatters in dental clinic. After dynamic disinfection, the quantities of colony-forming units may conform to the National Disinfection Technology Criteria.

OBJECTIVETo understand the demography changes and behaviors in drug users.

METHODSelf-reported questionnaires was used and longitudinal investigation was conducted in one of the detoxication centers in Beijing in 1998 and 2000. Drug users were randomly chosen.

RESULTSResults showed that age of drug users tend to become younger with the numbers of drug users aged below 25, increased from 18.7% in 1998 to 28.2% in 2000. Majority of drug users remained males, but the proportion of females seemed to increase. Distribution of occupation showed that the largest increase fell among individual enterprisers, from 15.2% in 1998 to 25.9% in 2000. With educational back-ground, the proportion of lower than elementary education level, including illiterate, increased. Fifty percent of drug users were unmarried which increased from 40.8% in 1998 to 53.2% in 2000. Needle sharing was quite common, 16.5% in 1998 and 11.9% in 2000, but the decrease was not statistically significant (P > 0.05). Fifty-seven point three percent of the injecting drug users did not have constant partners to share equipments. Proportion of extra-marriage sexual practice increased from 12.5% in 1998 to 27.5% in 2000, and significant difference (Chi-square = 12.50, P < 0.001). Multiple partners in extra-married drug users was also found (mean = 2). Compared to 1998, condom use during every sexual practice increased in 2000, but 47.7% drug users still never used condom.

CONCLUSIONIn summary, as the quick increase of drug users, sharing of injecting equipment and high-risk sexual behavior, including multiple partners and unprotected sex, were quite common, with the possibility of HIV epidemic in drug users.

Objective To look into the current distribution of iodine deficiency area in Shandong province and to guide the re-defined iodine deficiency area and to supplement iodine scientifically. Methods In 2008, 100 iodine deficiency counties(cities, districts), designated in Shandong province's "to supplement iodized salt to eliminate the hazard of iodine deficiency management regulations", were selected in the study. One to three samples were collected from water source which was used by the majority of local residents in the 100 iodine deficiency places and iodine concentration was tested by As3+-Ce4+ catalyzing spectrophotometry. Results A total of 65 716 water samples were collected. Sample recovery efficiency reached 99.8%(65 572/65 716). The median water iodine was 5.57 μg/L, with 82.05%( 1097/1337 ) of the township(town) met criteria for the classification of iodine deficiency areas(water iodine ＜ 10 μg/L), 17.43%(233/1337) of the township (town) water iodine moderate(water iodine 10 - 150 μg/L), and 0.52%(7/1337)of the township(town) should be defined high iodine areas(water iodine ＞ 150 - 300 μg/L). Conclusions The iodine deficiency areas should be redefined because water iodine concentrations of iodine deficiency areas have changed. We suggest that the smallest place to supply salt with different range of iodine content is set to the township(town).

Objective To learn the iodine nutritional status of the vulnerable population with different iodine level under the current level of iodized salt in Shandong province and to offer prevention and cure measures.Methods Five groups of vulnerable population including school children aged 8 - 10, pregnant, lactation women, infants and women of childbearing age from mountain areas ( Daiyue, Mengyin counties ) , plain ( Luxian,Gaomi counties ) and coastal (Zhaoyuan county ) of five different iodine deficient areas were investigated in 2007.The thyroids of children aged 8 - 10 were checked by palpation and B ultrasound, their edible salt iodine level was detected by direct titration. The lever of urinary iodine of vulnerable population was examined by arsenic and cerium speetrophotometry. Results The goiter rates of 8 - 10 year-old were 1.8%(9/514) and 1.2%(6/514), respectively by palpation and B-ultrasonic. The mean iodine of 501 edible salt samples was 30.95 mg/kg. The coverage rate of iodized salt was 94.6% (474/501). The rate of qualified iodized salt was 90.4% (453/501). The median of urinary iodine was 216.7 μg,/L. The urinary iodine of school children aged 8 - 10, pregnant, lactation women, infants and women of childbearing age were 234.0, 165.5, 162.4, 257.5, 233.0 μg/L, respectively. Conclusions Current iodine nutritional level is basically appropriate in all groups of vulnerable people. The current iodine content of iodized salt could meet the needs of population from different iodine deficient areas of Shandong province.

Objective: To evaluate the efficiency and safety of low intensity conditional regimen for children with Fanconi anemia (FA) receiving allogenic hematopoietic stem cells transplantation (allo-HSCT). Methods: Four patients diagnosed as Fanconi anemia were enrolled in this study. One patient received HLA-identical sibling donor hematopoietic stem cell transplantation, two patients underwent unrelated donor matched (UD) HSCT, and one patient received unrelated cord blood transplantation. The conditional regimen consisted of Busulfan with low dose of cyclophosphamide. Results: All 4 cases succeeded in allo-HSCT. The median time for neutrophils engraftment was 11(9-15) day, median time to platelets (PLT) engraftment was 12 (8-28) day. One case occurred with grade I of aGVHD, 1 case with hemorrhagic cystitis. No patient happened with hepatic veno-occlusive disease (VOD). Conclusion: Low intensity of conditional regimen is efficient and safe which should be recommended for FA patients with HSCT.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

This article reports a rare case of bilateral choroidal occlusion that occurred in a 24-year-old woman with antiphospholipid syndrome (APS) associated with systemic lupus erythematosus (SLE). This young lady concurred with aorta ventralis thrombosis and bilateral iliac artery occlusion when presented, and experienced a rapid deterioration of vision. She also has a history of recurrent miscarriage. Corticosteroid, immunosuppression and anticoagulation therapy were administered. Patients with APS associated with SLE are at risk for thrombotic phenomena, which may affect the ocular vessels of all sizes, including choroidal vessel. Our case alerts ophthalmologists and rheumatologists that bilateral choroidal occlusion may indeed be developed in patients with APS associated with SLE, and is a potential cause of visual morbidity.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.
