Objective To explore the key points of observing and nursing for patients with acute aortic dissection during the different stages postoperatively.Methods The nursing methods by stages were performed on 25 patients with acute aortic dissection.The stages included early stage(1 to 2 days after the operation), intermediate stage(3 to 14 days after the operation) and advanced stage(14 days after the operation and later).The key points of each stage were different.In the early stage,it needs to closely observe the circulation,the amount of blooding,the respiration system,the nerve system,and the occurrence of complications;and it also needs to do the syndrome-based nursing well,including calming,dropping blood pressure,blood transfusion,suction of phlegm and et al.In the intermediate stage,it needs to guide the daily life of the patients,including taking diet and drinking,activities,excretion and et al．In the advanced stage,it needs to do directions of discharging from the hospital and to prevent the recrudescence of aortic dissection. Results A total of 25 patients were improved in term of their symptoms or cured by our nursing care.The diagnosis was timely and the operation Was suitable.The observation and nursing by stages after the operation were reasonable.All the patients were discharged from the hospital after being healed,no death and no occurrence of serious complications.Conclusions It is helpful to improve the restoration of patients with acute aortic dissection by observing and nursing care by stages,which will play an important role in promoting the smooth healing of the patients and preventing the accidents and the reoccurrence of aortic dissection.

In view of the effective traditional Chinese medicine (TCM) in the treatment of clinical depression, the mechanism is not clear, this study attempts to research the cause of depression in a complex situation to lay the foundation for the next step of TCM curative effect evaluation. Based on the brain wave of 120 depression patients and 40 ordinary person, the change regulation of acetylcholine, dopamine, norepinephrine, depression neurotransmitters and excited neurotransmitters in the whole and various encephalic regions' multi-neurotransmitters of depression patients-serotonin are analysed by search of encephalo-telex (SET) system, which lays the foundation for the diagnosis of depression. The result showed that: contrased with the normal person group, the mean value of the six neurotransmitters in depression patients group are: (1) in the whole encephalic region of depression patients group the dopamine fall (P < 0.05), and in the double centralregions, right temporal region and right parietal region distinct fall (P < 0.01); (2) in the right temporal region of depression patients group the serotonin rise (P < 0.05); (3) in the right central region, left parietal region of depression patients group the acetylcholine fall (P < 0.05), left rear temporal region fall obviously (P < 0.01). The correlation research between antagonizing pairs of neurotransmitters and neurotransmitters: (1) the three antagonizing pairs of neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression neurotransmitters and excited neurotransmitters, in ordinary person group and depression patients group are characterizeed by middle or strong negative correlation. Serotonin and dopamine, which are characterized by weak negative correlation in the right rear temporal region of ordinary person group, are characterized by strong negative correlation in the other encephalic regions and the whole encephalic (ordinary person group except the right rear temporal region: the range of [r] is [0.82, 0.92], P < 0.01)/(depression patients group:the range of [r] is [0.88, 0.94], P < 0.01); acetylcholine and norepinephrine, in the whole and various encephalic region are characterized by middle negative correlation(ordinary person group:the range of [r] is [0.39, 0.76], P < 0.01 or P < 0.05)/(depression patients group: the range of [Ir] is [0.56, 0.64], P < 0.01); depression neurotransmitters and excited neurotransmitters are characterized by middle strong negative correlation (ordinary person group: the range of [r] is [0.57, 0.80], P < 0.01)/(depression patients group: the range of [r] is [0.68, 0.78], P < 0.01). (2) The two neurotransmitters which are not antagonizing pairs of neurotransmitters, serotonin and excited neurotransmitters, or acetylcholine and depression neurotra-nsmitters, or dopamine and depression neurotransmitters in the various encephalic regions are characterized by weak negative correlation. Serotonin and excited neurotransmitters are characterizeed by weak negative correlation (ordinary person group: in the right central region, left parietal region, double front temporal regions, right rear temporal region, the range of [r] is [0.25, 0.50], P < 0.01 or P < 0.05)/(depression patients group: in the whole encephalic regions, double parietal regions, double occipital regions, right front temporal region, left central region, left frontal region, the range of [r] is [0.18, 0.37], P < 0.01 or P < 0.05); acetylcholine and depression, neurotransmitters are characterized by weak negative correlation (ordinary person group: in the double frontal regions, left parietal region, left front temporal region, right rear temporal region, the range of [r] is [0.31, 0.46], P < 0.01 or P < 0.05)/(depression patients group: in double rear temporal regions, right front temporal region, double occipital regions, left central region, the range of [r] is [0.20, 0.32] , P < 0.01 or P < 0.05); do-pamine and depression neurotransmitters are characterized by weak middle negative correlation (ordinary person group: in left parietal region, right central region, left frontal region, left occipital region, double front temporal regions, the range of [r] is [0.33, 0.68], P < 0.01 or P < 0.05)/(depression patients group: in the whole region and other various regions except the left frontal region, right central region, the range of Irl is [0.21, 0.34], P < 0.01 or P < 0.05). Dopamine and acetylcholine or norepinephrine and serotonin are characterized by weak positive correlation in all encephalic regions. Dopamine and acetylcholine are characterized by weak positive correlation (ordinary person group: in left frontal region, right parietal region, left front temporal region and left rear temporal region, the range of [r] is [0.37, 0.46], P < 0.01)/(depression patients group: in the whole region and the orther various regions except the double central regions, the range of [r] is [0.23, 0.5], P < 0.01 or P < 0.05); norepinephrine and serotonin are characterized by weak positive correlation (ordinary person group: in double front temporal regions, double rear temporal regions, right frontal region and left parietal region, the range of [r] is [0.34, 0.48], P < 0.01 or P < 0.05)/(depression patients group: in the whole and various regions, the range of [r] is [0.18, 0.42], P < 0.01). The main differences between the depression patients group and ordinary person group are: (1) In the whole regin, left frontal region and right central region of depression patients group, the six neurotransmitters all fall normally (P < 0.05). (2) The percent of dopamine falling or including dopamine falling, or including dopamine falling and serotonin rising in depression patients group increases. The percent of dopamine falling or including dopamine falling in the whole region, right frontal region, right central region increases (P < 0.01), such as dopamine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. (3) The percent of acetylcholine falling, or including acetylcholine falling, or including acetylcholine falling and neurotransmitters (beta)-receptor)rising in depression patients group increases. The percent of acetylcholine falling, or including acetylcholine falling in the right temporal region, double central regions increases (P < 0.05 or P < 0.01), such as acetylcholine decreasing, acetylcholine decreasing neurotransmitters increaseng, acetylcholine decreasing neurotransmitters increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. It's showed in research that depression patients' brain are characterized by multi-neurotransmitters abnormal, the synchronous change of multi-neurotransmitters has some certain regularities, which are not the simple linear relation. It's conformed that the three antagonizing pairs, neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression eurotransmitters and excited neurotransmitters of ordinary person group and depression patients group, are both characterized by strong antagonizing relation, that the two neurotransmitters which are not antagonizing pairs of neurotransmitters are characterized by weak positive correlation or negative correlation, prompt maybe has the indirect causal relationship. And the change of six neurotransmitters in depression patients' various encephalic regions is rather complex. It's conformed preliminarily that the right frontal region and right central region are characterized by dopamine decreasing, acetylcholine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing excited neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing, acetylchoine decreasing neurotransmitters increasing, acetylcholine decreasing neurotransmitters increasing excited neurotransmitters decreasing and so on. Contrasted with the ordinary person group, the depression patients group have the notable difference.

OBJECTIVETo explore an appropriate measure to repair tissue defects and deformities in mandibulo-cervical region.

METHODSEighteen cases with severe tissue defects and deformity in jaw and neck were repaired with thoracic skin flap with multiple blood supply system in our unit from Jan. 2006 to Nov. 2008. Anterior cutaneous branch of transverse cervical artery, intercostal branch of internal thoracic artery and lateral thoracic artery were included in the pedicles.

RESULTSAll skin flaps survived, except in one patient in whom a small belb appeared at the distal end of the island flap with anterior cutaneous branch of transverse cervical artery, and it was healed after a few dressing changes. The functions and appearances were satisfactory after 6-month to 2-year follow-up, without showing secondary deformity.

CONCLUSIONSThe blood supply of thoracic skin flap is abundant and constant, which is an ideal method for repair of tissue defects and deformities in jaw and neck after taking into account some factors, such as the demand of the patient, general physical condition, and the size of the defect.

OBJECTIVETo observe the change of sexual function in male kidney transplant recipients.

METHODSSixty married males, aged 26 to 45 years, who had received kidney transplantations at least half a year before and whose serum creatinine (Scr) was under 200 mumol/L, were selected randomly in the study. Sexual functions were reviewed before and after the patients' renal failure and after kidney transplantations. The results were analyzed in Chi-Square test methods.

RESULTSTheir sexual functions, significantly aggravated after renal failure, were improved after kidney transplantations, but failed to return to normal. The recipients had a common worry that their sex lives might affect the renal grafts.

CONCLUSIONSKidney transplantations significantly improve the sexual functions of these renal failure patients. It is quite necessary to provide sexological guidance to kidney transplant recipients and their spouses.

OBJECTIVETo investigate the therapeutic effect of C-phycocyanin (C-PC) from Spirulina platensis on paraquat (PQ)-induced pulmonary fibrosis in rats.

METHODSA total of 90 healthy Wistar rats were randomly and equally divided into normal control group, model group (PQ group), and C-PC treatment group (C-PC group). Each rat in the PQ group and C-PC group were orally administered with a single dose of PQ (50 mg/kg) to establish a rat model of PQ poisoning. Then, the rats in the normal control group and PQ group were orally given saline solution (1 ml/100 g) every day, and the rats in the C-PC group were orally given C-PC (50 mg/kg) every day. Six rats were randomly selected from each group on days 1, 3, 7, 14, and 28. The inferior lobe of each rat's right lung was homogenized for the measurement of hydroxyproline (HYP) and maleic dialdehyde (MDA) levels and superoxide dismutase (SOD) activity. Parts of each rat's left lung were subject to HE staining and Masson staining for pathological observation, and the expression of transforming growth factor-β(1) (TGF-β(1)), nuclear factor-kappa B p65 (NF-κB p65), and tumor necrosis factor-α (TNF-α) in lung tissue was measured by immunohistochemistry.

RESULTSThe HYP levels on days 1, 3, 7, 14, and 28 and MDA levels on days 14 and 28 were significantly lower in the C-PC group than in the PQ group (P < 0.05, P < 0.01). The SOD activity was significantly higher in the C-PC group than in the PQ group on days 1, 7, 14, and 28 (P < 0.05, P < 0.01). The protein content of TGF-β(1) and the activities of NF-κB p65 and TNF-α in the PQ group and C-PC group were significantly higher than those in the normal control group, while the indices in the C-PC group were significantly lower than those in the PQ group (P < 0.05, P < 0.01). The pathological observation showed that C-PC could alleviate pulmonary alveolitis and fibrosis in rats with PQ poisoning.

CONCLUSIONC-PC can significantly inhibit PQ-induced pulmonary alveolitis and fibrosis in rats.

Objective To study the role of partial pressure of oxygen in the treatment of pulmonary hypertension induced by meconium aspiration syndrome. Methods Retrospective analysis was performed on 58 patients with meconium aspirate and pulmonary hypertension from January 1,2007 to December 31,2016, 28 patients in the death group,and 30 patients in the survival group. Blood gas analysis about two groups of children with mechanical ventilation were collected at four different time points:before mechanical ventilation ( 0 h) ,12 hours after mechanical ventilation,24 hours after mechanical ventilation and 72 hours after mechan-ical ventilation. The 80 mmHg(1 mmHg=0. 133 kPa) in blood gas analysis of the partial pressure of oxygen was used as the boundary point to study the effects about different blood oxygen partial pressures on the length of mechanical ventilation time in the survival group. Results Blood gas analysis showed that there were no significant differences in pH,partial pressure of oxygen,HCO3-,and lactic acid before mechanical ventilation in the two groups,but the pH values were significantly higher in the survival group after 12 h, 24 h,and 72 h of mechanical ventilation(t values:-2. 07,-3. 48,-7. 11;P <0. 05). Partial pressure of oxygen were higher in the surviving group at 12 h,24 h,and 72 h than those in the death group(t values-2. 87,-4. 88,-11. 29; P<0. 05). The HCO3-values of the survival group at 12 h,24 h and 72 h were higher than the death group, and the differences were statistically significant ( t values: -3. 90, -5. 60,-5. 76,P<0. 001). The lactic acid of survival group was significantly lower than the death group at 72 h after ventilation (t=5. 12,P<0. 001). Compared with the death group,partial pressure of carbon dioxide in 24 h,72 h decreased significantly in the surviving group(t values:5. 67,7. 60;P<0. 05). In the surviving group,the partial pressure of oxygen was maintained above 80 mmHg in 18 patients and the mechanical venti-lation time was (7. 17 ± 1. 95) d. The partial pressure of oxygen was below 80 mmHg in 12 patients of the surviving group and the mechanical ventilation time was (8. 67 ± 2. 50)d. The difference was statistically sig-nificant(t =12. 02,P <0. 001). Conclusion In the treatment of newborn with pulmonary hypertension caused by meconium aspiration,maintaining a higher pH value and a partial pressure of oxygen higher than 80 mmHg may be beneficial to the recovery of children with pulmonary hypertension.

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease and is one of the main causes of death and disability in neonates. The etiology and pathogenesis of neonatal ARDS are complicated. It is an acute pulmonary inflammatory disease caused by the lack of pulmonary surfactant (PS) related to various pathological factors. It is difficult to distinguish neonatal ARDS from other diseases. At present, there is no specific treatment method for this disease. Respiratory support, PS replacement, extracorporeal membrane oxygenation, nutrition support and liquid management are main treatment strategies. This paper reviews the research advance in etiology, clinical characteristics, diagnosis and treatment strategies of neonatal ARDS.

Objective To study the clinical efficacy of sublingual immunotherapy using standardized dermatophagoides farinae extract for children with combined allergic rhinitis and asthma syndrome. Methods Fifty-two children, from 4 to 14 years of age, with mite-sensitive combined allergic rhinitis and asthma syndrome were treated sublingually with standardized dermatophagoides farinae extract. The clinical efficacy was evaluated by monthly follow-up visits. After treatment for 1 or 2 years using the standardized dermatophagoides farinae extract, the asthma and rhinitis symptom scores, medication scores and adverse reactions before and after treatment were evaluated. SPSS 17.0 software was used to analyze the data. Results The allergic asthma symptom scores before treatment during the day were 3. 22 ±0. 66 and at night 2.05 ±0. 57. After 1 year of treatment, the day and night scores ( 1. 68 ± 0. 61 , 0. 94 ± 0. 32) respectively, were decreased significantly (q values were 15. 25 and 13. 78 respectively, all P < 0. 01 ). After 2 years of treatment, the scores (0. 61 ± 0. 28, 0. 43 ±0. 13 ) were also decreased significantly ( q values were 10. 29 and 6. 07 respectively, all P < 0. 01 ). The allergic rhinitis symptom scores and medication scores were 2. 34 ± 0. 59 and 3. 09 ±1.01 respectively before treatment and 1.21 ± 0. 46 and 1. 89 ±0. 64 after 1 year of treatment. The differences were significant ( q values were 15. 48 and 18. 61 respectively, all P<0.01). The allergic rhinitis symptom scores and medication scores were 1.02 ±0.37 and 1.49 ± 0. 38 after 2 years of treatment. There was no significant difference between 2 years of treatment and 1 year of treatment(q values were 2.53 and 2.78 respectively, all P >0.05). There were no severe adverse events during the treatment, except for mild mouth cavity discomfort. Conclusions Suhlingual immunotherapy using standardized dermatophagoides farinae extract is safe and effective in the treatment ofchildren with combined allergic rhinitis and asthma syndrome.

BACKGROUND: The aims of this study were to understand the molecular epidemiology of integron-associated gene cassettes in Acinetobacter baumannii across four hospitals in northern Taiwan and to clarify the relationship between the presence of integrons and antibiotic-resistant phenotypes. METHODS: Sixty-five A. baumannii isolates, collected from the patients of four regional hospitals in northern Taiwan in 2009, were tested for the presence of integrons and their associated gene cassettes. The susceptibility difference between integron-positive and integron-negative A. baumannii strains was analyzed. Antibiotic-resistant phenotypes among A. baumannii with different types of gene cassette array combinations were also compared. RESULTS: Around 72% of the A. baumannii isolates carried class 1 integrase genes. Despite this, only three gene cassette arrays were found in the integrons. Integron-positive strains were significantly more resistant to all the tested antibiotics than the integrase-negative strains. All the four types of A. baumannii with different gene cassette array combinations were multidrug-resistant in nature. Gene cassette array aacA4-catB8-aadA1 existed in all the integron-positive A. baumannii isolates. Repetitive-sequence-based PCR (rep-PCR) results revealed the prevalence of one major cluster of imipenem-resistant A. baumannii strains (84%) in the four regional hospitals. CONCLUSIONS: The presence of integrons with associated antimicrobial resistance gene cassettes can be used as a representative marker of multidrug resistance in A. baumannii. Some prevalent gene cassette arrays may exist among epidemiologically unrelated A. baumannii strains.
