RESUMEN

AIM: To explore the differences of corneal biomechanical parameters, serum Leptin and extracellular superoxide dismutase(ecSOD)levels in patients with non-proliferative diabetic retinopathy(NPDR)or proliferative diabetic retinopathy(PDR).METHODS: This article is a prospective study. A total of 118 patients with type 2 diabetes mellitus(T2DM)and diabetic retinopathy(DR)who were admitted to our hospital from May 2020 to May 2022 were selected, and they were divided into NPDR group(n=57)and PDR group(n=61)according to the degree of lesion. Another 54 patients with T2DM but no retinopathy and 52 healthy individuals were set as NDR group and control group. Then the differences in the corneal biomechanics measured with [central corneal thickness(CCT), intraocular pressure(IOP), spherical equivalent(SE), the first applanation time(A1T), the first applanation length(A1L), deformation amplitude(DA)] and serum Leptin and ecSOD levels were analyzed, and multivariate Logistic regression analysis was conducted to analyze the high-risk factors affecting the occurrence of PDR.RESULTS: The CCT, IOP and A1T in PDR and NPDR groups were higher than those in control and NDR groups, and DA was lower than those in control and NDR groups(all P<0.05), and the CCT, IOP and A1T in the PDR group were higher than those in the NPDR group(all P<0.05). The levels of serum Leptin and ecSOD in PDR group, NPDR group and NDR group were higher than those in the control group(all P<0.05). The course of DM, CCT, IOP, A1T, and serum Leptin and ecSOD levels between NPDR group and PDR group were statistically significant(all P<0.05). Multivariate Logistic regression analysis denoted that DM course, CCT, IOP, A1T, Leptin, and ecSOD are risk factors that affect the occurrence of PDR, while DA is a protective factor that affects the occurrence of PDR(all P<0.05). CONCLUSION: CCT, IOP and levels of serum Leptin and ecSOD in PDR patients were significantly increased compared to those in the NPDR patients, while DA was significantly reduced. Furthermore, CCT, IOP, A1T and levels of serum Leptin and ecSOD were risk factors affecting the occurrence of PDR, while DA was a protective factor affecting the occurrence of the PDR.

RESUMEN

OBJECTIVE@#To compare the clinical efficacy on lumbar muscle strain with cold and dampness between the different operation sequences of acupuncture and cupping therapy.@*METHODS@#Seventy-six patients with lumbar muscle strain with cold and dampness were randomly divided into an acupuncture + cupping group (A + C group, 38 cases) and a cupping + acupuncture group (C + A group, 38 cases, 1 case dropped off). In the A + C group, cupping therapy was delivered 10 min after the end of treatment with acupuncture, while in the C + A group, acupuncture therapy was exerted 10 min after the end of treatment with cupping. Acupuncture was applied to Mingmen (GV 4), Yaoyangguan (GV 3), ashi point and bilateral Shenshu (BL 23), Dachangshu (BL 25), Weizhong (BL 40) and Yanglingquan (GB 34), and the needles were retained for 30 min in each intervention. Flash cupping was operated along the bilateral sides of the lumbar spine for 3 min, and the cups were retained for 10 min at bilateral Shenshu (BL 23), Dachangshu (BL 25) and ashi points. The intervention was delivered once every two days, 3 times weekly, for 3 weeks totally in each group. The scores of visual analogue scale (VAS) and Oswestry disability index (ODI), TCM syndrome score and the mean temperature of the lumbar region before and after treatment were compared between the two groups. The safety and the clinical efficacy were assessed for the interventions of the two groups.@*RESULTS@#Compared with the values before treatment, except for the sleep score of ODI, the VAS scores, ODI scores and TCM syndrome scores were decreased after treatment (P<0.01, P<0.05); while the mean temperature of the lumbar region was increased (P<0.01) in both groups. After treatment, the VAS score and the pain score of ODI in the C + A group were lower than those in the A + C group (P<0.05). The incidence rate of adverse reactions of the C + A group was lower than that of the A + C group (P<0.01). The effective rate in the A+C group was 92.1% (35/38), that in the C+A group was 94.6%(35/37), there was no statistical difference between the two groups (P>0.05).@*CONCLUSION@#Different operation sequences between acupuncture and cupping therapy obtain the similar efficacy on lumbar muscle strain with cold and dampness, but cupping therapy delivered prior to acupuncture has certain advantages in relieving pain and improving safety.

RESUMEN

Standardized residency training is the only way for medical students to grow into qualified doctors. Since the implementation of pediatric standardized residency training nationwide in 2014,the training has been progressing smoothly and has made remarkable achievements. In order to further adapt to the status of residential training,meet the needs of pediatric training nationwide and improve the quality of pediatric training,the Pediatric Professional Committee organized experts to brainstorm and revise the two criteria, "Pediatric Criteria for Standardized Residency Training Base" and "Pediatric Criteria for Standardized Residency Training Contents". The revision of these two criteria follows the principles of continuity,accessibility,advancement and consistency. Revision was focused on lowering the scale of the base,proposing the concept of professional group,making rotation of specialty flexible,and strengthening stratified training. We hope to improve the capability of base to improve the comprehensive ability of residential students without increasing the bed size. It is believed that the pediatric standardized residency training system will provide a solid foundation for the pediatric training through providing good policy guidance,support,and medical and educational cooperation.

RESUMEN

Medicine is a highly practical science. A high-quality clinical doctor must go through strict college education,post-graduation education and follow-up continuing education. Since the implementation of standardized resident training in 2014,great achievements have been achieved:great attention has been paid to residential training,about 500 pediatric professional training bases have been set up nationwide,and software and hardware(e.g. simulation centers and teacher training)have been upgraded. Since 2017,the state has gradually launched specialty training. In the process of promoting resident and specialty training,some problems were exposed. Hence,pediatrician training needs to be in line with the“top-level design”of national health,such as the system of tiered medical services,and family physician contract system;to handle the phases and continuity of different stages of medical education;to learn foreign excellent experience based on the national conditions of China. With good top-level design,medical and educational collaboration,learning international advanced experience based on our national conditions,a standardized medical training system with Chinese characteristics will be built,which will enhance the overall level of our medical team.

RESUMEN

<p><b>OBJECTIVE</b>We aimed to elucidate the rates of repeat HIV testing and incident HIV diagnosis, and baseline CD4+ T cell count among individuals attending HIV voluntary counseling and testing (VCT) clinics in Wuxi, China.</p><p><b>METHODS</b>A repeat HIV testing within 12 months was recorded if individuals had their first test with negative results, during 2013-2014 and retested within 12 months. An incident HIV diagnosis was recorded if individuals had their first test with negative results, during 2013-2015 and had a subsequent positive result at any point by the end of 2015. Data on HIV testing and diagnosis among individuals attending 32 VCT clinics from 2013 to 2015 and HIV diagnosis from other clinical services in Wuxi, China, were retrieved. A multivariate logistic regression model was used to analyze factors associated with repeat HIV testing. Cox regression was used to evaluate factors associated with incident HIV diagnosis.</p><p><b>RESULTS</b>From 2013 to 2014, 11,504 individuals tested HIV negative at their first recorded test, with 655 (5.7%) retesting within 12 months. Higher repeat HIV testing within 12 months was associated with male gender [adjusted odds ratio (aOR) = 1.7, 95% confidence interval (CI): 1.4-2.2], risk behaviors [commercial heterosexual behaviors (aOR = 1.4, CI: 1.1-1.6), male-male sexual behaviors (aOR = 3.7, CI: 2.7-4.9)], injection drug use (aOR = 9.9, CI: 6.5-15.1), and having taken HIV tests previously (aOR = 2.0, CI: 1.6-2.4). From 2013 to 2015, 1,088 individuals tested negative on HIV test at their visit and at ⋝ 2 subsequent tests; of them 30 had incident HIV diagnosis. The overall rate of incident HIV diagnosis among all VCT individuals was 1.6 (95% CI: 1.1-2.1) per 100 person-years. Incident HIV diagnosis was associated with male gender [adjusted hazard ratio (aHR) = 8.5, 95% CI: 1.9-38.1], attending hospital-based VCT clinics (aHR = 7.8, 95% CI: 1.1-58.3), and male-male sexual behavior (aHR = 8.4, 95% CI: 1.5-46.7). Individuals diagnosed at VCT clinics had higher CD4+ T cell count compared with those diagnosed at other clinical services (median 407 vs. 326 copies/mm3, P = 0.003).</p><p><b>CONCLUSION</b>VCT individuals in Wuxi, China, had a low repeat HIV testing rate and high HIV incidence. VCT-clinic-based interventions aimed at increasing repeat HIV testing are needed to detect more cases at an earlier stage, especially among individuals at high risk for HIV infection such as men who have sex with men.</p>

RESUMEN

BACKGROUND:Most bone marrow mesenchymal stem cel s are infused intravenously and have very low efficiency of homing to the bone marrow. However, cel infusion via the femoral approach is little reported. OBJECTIVE:To explore the distribution of luciferase gene modified red fluorescent protein transgenic bone marrow mesenchymal stem cel s in vivo through different infusion routes. METHODS:Luciferase gene modified bone marrow mesenchymal stem cel s at different gradients (5×106, 1×106, 1×105, 1×104) were seeded or injected into the in vitro pore plate or free femurs to observe the fluorescence imaging and select the best concentration of cel s. Luciferase gene modified bone marrow mesenchymal stem cel s at the best cel concentration were injected into the mice via the femur and the tail vein, respectively. The distribution of fluorescence and cel number in the mice were explored by using bioluminescence, pathological examination, flow cytometry and quantitative PCR. RESULTS AND CONCLUSION:Ex vivo fluorescence intensity of luciferase gene modified bone marrow mesenchymal stem cel s was positively correlated with the cel concentration;fluorescent cel s in vivo appeared in the femur first and then quickly spread to the lungs in the femur group, while fluorescent cel s in the tail vein group spread to the lungs quickly after cel infusion. Fluorescent cel s could be seen in the spleen, liver and other organs 24 hours later in the two groups. The distribution and migration of cel s in mice could be observed successful y by bioluminescence;5 minutes after cel infusion, the lungs of mice in the two groups began to emit fluorescence that could spread to the liver, spleen and other tissues 24 hours later, and the fluorescence intensity reached its peak after 15 minutes. The distribution of bone marrow mesenchymal stem cel s in mice had no significant difference between the femur group and the tail vein group. To conclude, cel injection through the bone marrow cavity and tail vein fails to promote the homing of bone marrow mesenchymal stem cel s to the bone marrow.

RESUMEN

<p><b>OBJECTIVE</b>To compare the therapeutic efficacy of patients with neonatal ABO hemolytic disease treated with introvenous immunoglobin G (IVIG) by different modes of administration.</p><p><b>METHODS</b>Ninety-three in patients with neonatal ABO hemolytic disease treated in our hospital were divided into group A (31 cases), B(31 cases) and C (31 cases). Based on basic treatment, the patients in group A were treated by a single high dose of IVIG (1 g/kg), patients in group B were treated by multiple low-dose of IVIG (0.5 g/kg), and the patients in group C treated by placebo without IVIG used as controls. The phototherapy time, jaundice time in 3 groups were observed; the total bilirubin levels in 3 groups were compared before and after treatment; the incidence of anemia, the rate of blood transfusion and the occurrence of bilirubin encephalopathy were compared after treatment between 3 groups.</p><p><b>RESULTS</b>The phototherapy time, jaundice time in group A were statistically significantly shorter than those in the group B and C (P<0.05), but there was not statistical significantly difference between group B and C(P>0.05). Before treatment, serum TBIL level in 3 groups was not significantly different (P>0.05); and after treatment for 24 h and 48 h, the serum TBIL levels in group A were significantly lower than that in group B and C (P<0.05); after treatment for 72 h, the serum TBIL level in group A was all lower than 34.2 µmol/L; before treatment, Hb levels in 3 groups were not significantly different (P>0.05); Hb level in group A was significantly higher than that in group B and C after treatment for 24 h, 48 h and 72 h (P<0.05). The incidence of anemia in group A after treatment was significantly lower than that in group B and C, and that in group B significantly lower than that in group C(P<0.05). The rate of blood transfusion in group A was significantly lower than that in the group B and C (P<0.05); the rate of blood transfusion was not statistically significantly different between group B and C(P>0.05).</p><p><b>CONCLUSION</b>The single high dose of IVIG infusion can effectively reduce the serum TBIL level, shorten treatment time and reduce the incidence of anemia and blood transfusion, so the therapeutic efficacy is significantly improved.</p>

RESUMEN

Type 1 diabetes mellitus [T1DM] is the most common form of diabetes in young children. Serious optic complications, e.g. diabetic retinopathy and diabetic cataract involvement, are not usually detected in T1DM patients at the onset of the disease. Two girls aged 11 years and 9 years were hospitalized in our unit in 2008 and 2009. They presented cataracts 1 and 6 months before the diagnosis of T1DM, respectively. After blood glucose level was controlled by insulin therapy, the cataract was resolved, totally in one and partly in the other girl. Meanwhile, visual acuity of both cases recovered, closely associated with fluctuation of plasma glucose level. In this study, we describe the symptoms, probable mechanism and treatment of diabetic cataract. Early antihyperglycemic therapy and maintenance of stable blood glucose level may reverse acute diabetic cataract or prevent it from getting worse

RESUMEN

<p><b>OBJECTIVE</b>Obese children and adolescents are often complicated with the abnormalities of lipid and glucose metabolism, which are often associated with adulthood hypertension, diabetes and cardiovascular disease. In this study, the blood lipids, blood pressure and carotid arterial intima-media thickness (IMT) in obese children and adolescents were measured to investigate the relationship between the dyslipidemia and early vascular lesions.</p><p><b>METHOD</b>A total of 580 obese children and adolescents aged from 7 to 17 years of age were enrolled from 3 hospitals from Jan. 2008 to Sept. 2009. They were divided into 2 groups according to their blood lipoid levels. Ortholiposis group included 100 males and 52 females with a mean age of 10.47 years and a mean body mass index (BMI) of 28.28 kg/m(2). Dyslipidemia group included 305 males and 123 females with a mean age of 10.83 years and a mean BMI of 27.60 kg/m(2). Physical examination, and measurement of blood lipid, glucose and liver enzyme were taken. Carotid IMT was measured for 285 subjects.</p><p><b>RESULT</b>(1) Hypertension was found in 12.5% (19/152) and 20.1% (86/428) patients in ortholiposis and dyslipidemia groups, respectively, with a significant difference (χ(2) = 4.362, P = 0.037). The OR was 1.760 with 95% confidence interval of 1.030 - 3.008. Higher prevalence of hypertension was found in patients with dyslipidemia. (2) The left, right and mean common carotid IMTs of dyslipidemia group were higher than those of ortholiposis group without significant difference (all P > 0.05). The left, right and mean internal carotid IMTs in dyslipidemia group were (0.66 ± 0.15) mm, (0.65 ± 0.15) mm and (0.65 ± 0.15) mm, respectively while these in ortholiposis group were (0.62 ± 0.13) mm, (0.60 ± 0.13) mm and (0.61 ± 0.12) mm, respectively (P < 0.05 for all). (3) Bivariate correlation analysis showed that systolic blood pressure was positively correlated with age, BMI, BMI Z score, waist circumference, hip circumference, uric acid, alanine transaminase, triglyceride, fasting insulin and insulin resistance index (P < 0.05 for all). Moreover, mean carotid and internal carotid IMTs were positively correlated with age, BMI, waist circumference, hip circumference, and triglyceride (all P < 0.05). Multiple linear regression analysis showed that hip circumference and insulin resistance index were independent determinants of systolic pressure. Waist circumference was independent determinant of mean common and internal carotid IMT and triglyceride was independent determinants of mean internal carotid IMT.</p><p><b>CONCLUSION</b>(1) Vascular lesions, including hypertension and thicker tunica intima are common in obese children and adolescents. (2) Vascular lesions are closely related with dyslipidemia, and waist circumference and hypertriglyceridemia are the risk factors.</p>

RESUMEN

<p><b>OBJECTIVE</b>To evaluate the value of reoperation for local recurrence of rectal carcinoma.</p><p><b>METHODS</b>The data of 62 cases with post-operative local recurrence of rectal carcinoma were analyzed retrospectively.</p><p><b>RESULTS</b>All the 62 patients received reoperation. Thirty two of those patients were treated with radical resection (16 patients combined multiple organ resection), 6 palliative resection, 11 colostomy, and 13 laparatomy only. The 1-, 3- and 5-year survival rates in the patients accepted radical resection were 90.6%, 59.4% and 18.8% respectively. But in patients undergone palliative resection and combined therapy, survival time was 6-24 months with median survival time of 16 months. The patients, accepted laparatomy and intra-abdominal chemotherapy, all died within 2-14 months postoperatively. For patients with postoperative recurrence time >5 years, <2 years and 2-5 years, the reoperation resection rates were 100%(11/11), 62.9%(22/35), and 31.3%(5/16) respectively, and there were significant differences among 3 groups (P<0.01). The rate of reoperation resection of pure local recurrence was 80.0%(32/40). The rate of reoperation resection of local recurrence, associated with near organ invasion, was 27.3%(6/22). The difference was significant(P<0.01). The reoperation resection rate of first operation with Dixon or Miles was 61.9%(26/42) and 30.0%(6/20), and the difference was significant as well(P<0.05).</p><p><b>CONCLUSIONS</b>The recurrence of rectal carcinoma still needs positive operation in order to prolong the survival time and improve the quality of life of the patient. First operative procedure, post-operative recurrence time and recurrence type are important factors of reoperative resection.</p>

RESUMEN

<p><b>OBJECTIVES</b>Metabolic syndrome (MS) in adolescents was reported to be closely associated with cardiovascular diseases in adulthood. However, no unified treatment measure for MS in adolescents is currently available. The aim of this study was to measure the changes of serum adiponectin levels, insulin sensitivity and other biochemical markers after metformin therapy in adolescents with MS, which might provide some information for set up a unified therapeutic measure for MS in adolescents.</p><p><b>METHODS</b>In this study, 348 moderately or severely obese adolescents and 24 non-obese healthy adolescents matched in age and sex were enrolled. The obese group included 208 males and 140 females aged from 7 to 16 years (11.5 +/- 2.1 years). Oral glucose tolerance test and biochemical markers measurement were done to all these subjects. Whole body insulin sensitivity index (WBISI), homeostasis model assessment-insulin resistance (HOMA-IR) and fasting serum adiponectin were compared among 36 adolescents with MS (who had two or three abnormalities of hyperglycosemia, hypertension or dyslipidemia), 61 simple obese subjects without abnormality of biochemical markers and 24 healthy controls. Moreover, the changes of WBISI, HOMA-IR and adiponectin levels in 20 cases with MS after metformin therapy for 3 months were measured.</p><p><b>RESULTS</b>(1) HOMA-IR in control group (1.3), simple obese group (2.3) and MS group (4.9) increased by turns (F = 54.08, P < 0.001). WBISI and serum adiponectin in control group, simple obese group and MS group decreased by turns with significant difference [89.6, 22.8 and 10.7, F = 30.06; (7.1 +/- 2.6), (5.9 +/- 1.9), (2.8 +/- 0.9) mg/L, F = 64.93; P < 0.01 for all]. (2) HOMA-IR after metformin therapy decreased [5.7 (1.9-12.4) vs. 2.9 (0.9-7.4), t = 5.05, P < 0.01]; while the serum adiponectin levels increased with significant differences [(3.0 +/- 0.9) mg/L vs. (6.1 +/- 1.9) mg/L, t = 6.19, P < 0.01]. Systolic blood pressure [(132.4 +/- 7.5) mm Hg vs. (116.6 +/- 9.1) mm Hg, t = 8.36, P < 0.01], 2-hour glucose [(8.2 +/- 2.9) mmol/L vs. (5.3 +/- 1.0) mmol/L, t = 3.96, P < 0.01], triglyceride [(2.8 +/- 1.2) mmol/L vs. (1.3 +/- 0.9) mmol/L, t = 4.22, P < 0.01], total cholesterol [(4.9 +/- 0.6) mmol/L vs. (4.0 +/- 0.6) mmol/L, t = 4.72, P < 0.01], alanine aminotransferase [80.5 (29.0-286.0) U/L vs. 56.0 (23.0-163.0) U/L, t = 3.80, P < 0.01].</p><p><b>CONCLUSION</b>Insulin sensitivity in adolescents with MS was lower than that of simple obese group. Metformin can improve or ameliorate adiponectin levels, insulin sensitivity and some clinical markers.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the expression of vascular endothelial growth factor C (VEGF-C) and survivin protein in human gastric carcinoma,and to evaluate their clinical implications.</p><p><b>METHODS</b>The expressions of VEGF-C and survivin protein in tumor tissues,matched para- tumor tissues from 97 cases with gastric cancer and normal tissues form 20 normal controls,were determined by immunohistochemistry. Their relationships with clinicopathological parameters were analyzed.</p><p><b>RESULTS</b>The positive rate of VEGF-C and survivin protein in tumor tissues (66.0% and 57.2%) was significantly higher than those in matched para-tumor tissues normal tissues (P< 0.05). There were no significant differences in VEGF-C expression considering tumor size,localization,histological grade,venous invasion,and distant metastasis (P > 0.05), while its expression was correlated with serosal infiltration, lymphatic invasion, lymph node metastasis and TNM stage III-IV (P< 0.05). The survivin expression was significantly related with serosal infiltration,lymphatic invasion, regional lymph node metastasis,distant metastasis, and TNM stage III- IV (P< 0.05), but not with histological grade, localization,venous invasion,and tumor size (P > 0.05). The 1, 3 and 5-year survival rates of the patients with positive VEGF-C or survivin protein were significantly lower than those of the patients with negative VEGF-C or survivin (P< 0.05), respectively. In additional,the expression of VEGF-C was positively correlated with survivin expression in gastric carcinoma (P< 0.01).</p><p><b>CONCLUSION</b>The expressions of VEGF-C and/or survivin may be indicators for poor prognosis of gastric carcinoma.</p>

RESUMEN

<p><b>OBJECTIVE</b>Numerous studies in children with growth hormone deficiency (GHD) show that recombinant human growth hormone (rhGH) treatment results in significant catch-up growth, but some papers reported that the children who underwent rhGH therapy might be at increased risk of diabetes. The aim of this study was to investigate the effects of rhGH treatment on blood glucose and insulin metabolism in children with GHD and the relationship between growth hormone (GH) and glucose homeostasis.</p><p><b>METHODS</b>In this study, 44 children with GHD treated with rhGH [0.1 U/(kgxd)] and age- and sex-matched 20 healthy children were enrolled. The GHD group included 28 males and 16 females aged from 4.5 to 16.5 years (mean 10.4 +/- 2.6 years), including 18 cases of complete GHD and 26 cases of partial GHD. The sexual development stage of all subjects was in Tanner I. Oral glucose tolerance tests (OGTT) were done, and body mass index (BMI), serum insulin-like growth factor-1 (IGF-1) level and insulin resistance by homeostasis model (HOMA-IR) were measured at the time of diagnosis and every 3 months after rhGH therapy. Continuous glucose monitoring system (CGMS) was applied for two cases with hyperglycemia.</p><p><b>RESULTS</b>(1) Fasting glucose and IGF-1 levels increased since 3 months of treatment and did not decrease since then. The levels of fasting glucose and IGF-1 at every time points of rhGH therapy were higher than the levels at the time of diagnosis (F = 6.81, P < 0.01; F = 7.31, P < 0.01, respectively). HOMA-IR and fasting insulin levels were increased since 3 and 9 months of treatment (P = 0.001 and P = 0.021, respectively). They decreased after 12 months of therapy and the levels at 18 months of therapy were similar to that at diagnosis. (2) Pearson correlation analysis showed that HOMA-IR was positively correlated with BMI, IGF-1 and the duration of treatment (r = 0.251, 0.437, 0.281, P < 0.01, respectively). The curve between HOMA-IR and duration of therapy was similar with parabola and the quadratic equation obtained was as follows: HOMA-IR = 1.5048 + 0.2177 x duration of therapy (months)-0.0103 x duration of therapy (months)(2) (r(2) = 0.147, F = 14.16, P < 0.01). (3) Two cases had transitory hyperglycemia. Their fasting glucose levels were all higher than 7.1 mmol/L. The glucose levels returned to normal after 1 month and 5 days respectively. OGTT and CGMS showed that their plasma glucose levels were normal after rhGH therapy was applied again.</p><p><b>CONCLUSION</b>The children who underwent rhGH therapy may be at increased risk of insulin resistance (especially during the first year) and the therapy may even induce transitory glucose metabolic disorder in a very small proportion of patients. Circulating IGF-1 may participate in the control of insulin sensitivity and play an important role in the hormonal balance between GH and insulin. It may be necessary to monitor glucose metabolism and IGF-1 for all children who are treated with rhGH therapy.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the feasibility, safety and efficacy of Cypher drug-eluting stent implanted after the emergency percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI).</p><p><b>METHODS</b>From Nov. 2002 to Dec. 2004, 186 patients with STEMI treated by emergency PCI were included into this study. The incidence of major adverse cardiovascular event (MACE), stent thrombosis and restenosis were evaluated during 6 months follow-up after PCI.</p><p><b>RESULTS</b>One hundred and sixty-eight patients were successfully treated by emergency PCI and there were no complication during the procedure. The rates of successful treatment were 100%. One hundred and seventy-five Cypher drug-eluting stents were successfully implanted into 171 target lesions. There was one case with acute stent thrombosis among 186 patients, and the MACE and mortality were 2.4% and 1.8%, respectively, during the first one month follow up. Six months later, the MACE was 4.2% and the mortality was 2.4%. The in-stent thrombosis and restenosis rates were 1.2% and 1.8%, respectively, when evaluated by angiography and clinic follow up at six months after PCI.</p><p><b>CONCLUSION</b>Implanting a Cypher drug-eluting stent in STEMI patients during emergency PCI is as safe and effective as a conventional bare stent. Cypher drug-eluting stent can reduce restenosis rate and MACE in STEMI patients treated with emergency PCI.</p>

RESUMEN

<p><b>OBJECTIVE</b>To analyze factors relevant to retarded intellectual development in infants born to mothers with autoimmune disease of thyroid.</p><p><b>METHODS</b>All the term newborns born to mothers with autoimmune thyroid disease (selection criteria) without asphyxia in all county, city, and provincial hospitals in Zhejiang province (except for Ningbo City) from July 2001 to June 2003 were enrolled through Zhejiang provincial neonatal disease screening network system. The control group was consisted of the neonates who were born to mothers without thyroid disease in these hospitals during the same period. Heel capillary blood samples were collected from the neonates older than 3 days in local hospitals and sent to the center of Zhejiang provincial neonatal disease screening network system. TSH levels were measured by Time Difference Fluorescent Analysis Device (1420 II type, EGG Company, US). If the level of TSH was higher than 9 mU/L, their mothers were called back to the center with their infants within 3 days. If the level of TSH was normal, they were called back to hospitals at age of 28 - 35 days of infants. The pattern of maternal thyroid disease, duration, thyroid function, the history of maternal drug administration, maternal age, gestational age and body weight of the neonates were recorded. The neonatal and maternal serum thyroid function tests were re-performed and the serum TPOAb, TGAb, TRAb and TSAb levels in both neonates and their mothers were measured as well. A 1-year follow-up study was done and all these subjects were investigated by means of Gesell development schedules by special investigators at the age of 1, 3, 6 and 12 months. The results were expressed as developmental quotient. Case-sectional study was performed. Statistical analyses were conducted using SPSS software. The multiple logistic regression analysis was used to analyze factors which might have effect on infantile personal-social ability, adaptive ability, gross motor ability or the fine-motor ability. One-way ANOVA was used to compare those five subfields ability followed by LSD multiple comparisons and Dunnet's C test was used when variances were not equal. Correlation analysis was used to compare the anti-thyroid antibody between neonates and their mothers.</p><p><b>RESULTS</b>Poor personal-social ability, adaptive ability, gross motor ability and fine motor ability of infants born to mothers with autoimmune thyroid diseases were found as compared to the infants born to healthy mothers (P < 0.01). Moreover, the infants born to mothers with Hashimoto's thyroiditis had significantly poorer fine motor ability and adaptive ability than those born to mothers with Grave's disease (P < 0.05). The Spearman correlation coefficients of TPOAb, TGAb, TRAb and TSAb were 0.636, 0.574, 0.619 and 0.473, respectively, and all the P values were lower than 0.01.The multifactor logistic regression analysis showed that infantile TPOAb levels and maternal TRAb levels were associated with infantile personal-social ability, adaptive ability, and gross motor; while maternal TPOAb levels and thyroid function during gestation were associated with infantile fine-motor ability (P < 0.05).</p><p><b>CONCLUSION</b>Maternal autoimmune thyroid diseases during pregnancy had adverse effects on intellectual development of infants. The maternal levels of TPOAb, TRAb and thyroid status were associated with the infantile personal-social ability, adaptive ability, gross motor and fine motor development. In order to reduce the effect on infant, it is necessary to treat adequately the maternal autoimmune thyroid diseases during pregnancy.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the diagnosis and treatment of benign duodenal tumor.</p><p><b>METHODS</b>Clinical data of 14 patients with benign duodenal tumor confirmed pathologically or by operation from Oct.1988 to Oct.2001 were analyzed retrospectively.</p><p><b>RESULTS</b>Of 14 patients, 5 had Brunner's grand adenoma, 4 mesenchymoma, 2 leiomyoma, 2 hemangioma, 1 lipoma. Upper abdominal discomfort (64% ), gastrointestinal bleeding(50% ) and abdominal pain(20% ) were common manifestations. All cases received gastroscopy and only one case was diagnosed. Five cases received duodenoscope and the diagnosis was confirmed in 4 cases. Nine cases received hypotonic duodenography and lesions were found in 8 cases. Digital subtraction angiography was performed in 3 cases and detected all lesions. Computed tomographic scan and B-ultrasound were performed in 2 cases and only one case was diagnosed. Eleven cases (79% ) got definite diagnosis before operation. Tumor resection was performed in all patients. Perioperative death occurred in one patient. No recurrence occurred in 13 cases after following up from 2 to 11 years.</p><p><b>CONCLUSION</b>Upper abdominal discomfort and gastrointestinal bleeding are common features in patients with benign duodenal tumor. Duodenoscopy and hypotonic duodenography are good diagnostic approaches. Surgical tumor resection is the first choice of treatment.</p>
