The ischemic heart disease has been endangering human health seriously. Although there are many kinds of anti-ischemic drugs, most of them are lacking in tissue specificity, which together with a remarkably reduced blood circulation in the ischemic zone often lead to a quite low drug distribution in the targets. Myocardial ischemia can cause a lot of pathophysiological changes, such as the enhanced permeability of the endothelial cell membrane, the up-regulated expression of various cell adhesion molecules on endothelium, the exposure of intracellular antigenic components, the decrease of pH within the ischemic zone, and so on. To date, some of these changes have been exploited with limited success to gain the passive, active and physicochemical targeting of diagnostic or therapeutic drugs to myocardial ischemic regions. However, more effective delivery strategies are still eagerly needed. Here, we reviewed and discussed the potential targeting-delivery mechanisms and strategies, used or may be used in the future, for myocardial ischemic regions.

Purpose:To investigate the therapeutic effect of PEFC chemotherapy regimen (cisplatin or carboplatin,etoposide,fluorouracil and cyclophosphamide) on primary carcinoma of fallopian tube.Methods:41 patients with primary carcinoma of fallopian tube were divided into two groups: 20 patients in PEFC group received PEFC chemotherapy; 21 patients in CAP group received CAP chemotherapy. The therapeutic effects of the two groups were compared.Results:1 , 3 , 5 year progression free survival rate of PEFC group and CAP group were: 100%, 67.34%, 67.34%; 76 19%, 51 88%, 45 40% respectively ( P

BACKGROUND:Polytetrafluoroethylene (PTEE) as a nose filer material has advantages on the resistant to corrosion, chemical stability and so on. However, its linear expansion coefficient is large easily leading to infection and rejection, and its application has some limitations. OBJECTIVE:To compare the cel toxicity, inflammatory infiltrates and biocompatibility indexesin vivo between PTEE and PTEE combined with type Ⅰ colagen. METHODS: MTT method was used to detect the relative proliferation rate of L929 cels cultured with PTEE extract or PTEE combined with type Ⅰ colagen extract; an electron microscope was used to observe the cel growth. PTEE or PTEE combined with type Ⅰ colagen was embedded under the nasal dorsal fascia of New Zealand white rabbits for 7 days, and hematoxylin-eosin staining was used to detect whether nasal mucosa epithelial tissue had inflammatory infiltration. Systemic toxicity, alergies, pyrogen reaction and deaths of rabbits were observed after injection of two kinds of material extracts by ear vein. RESULTS AND CONCLUSION: The cytotoxicity and inflammatory infiltration were milder in PTEE combined with type Ⅰ colagen group than PTEE group (P < 0.05). The alergic reactions and pyrogen reactions were fewer in PTEE combined with type Ⅰ colagen group than PTEE group (P < 0.05). These findings indicate that PTEE combined with type Ⅰ colagen as the nose filer material has better biocompatibility.

Lymph node metastasis is the main prognostic factor of endometrial cancer patients.As the metastasis of early endometrial cancer patients is very low,it remains a controversy whether these patients are necessary to undergo conventional lymphadenectomy and a challenge to confirm the scope of lymph node dissection.We intend to demonstrate the application of lymphadenectomy in patients with early endometrial cancer via the impact of lymphadenectomy on the prognosis of these patients.The risk factors for lymph node metastasis of endometrial cancers were analyzed to explore its value in the surgical option.Furthermore,the guidance of sentinel lymph node in surgical staging and prognostic prediction of early endometrial cancer was explored to clarify the applied condition and scope of lymphadenectomy in these patients.

Objective Pulmonary sequestration (PS) is a rare disease,and its clinical symptoms are usually related to subsequent pulmonary infections.We analyzed the clinical characteristics of PS complicated by aspergillosis,and reviewed related literature,so as to disclose the association between these two diseases.Methods Sixty-nine patients with surgery-confirmed PS in Peking Union Medical College Hospital between January 1990 and December 2013 were retrospectively analyzed,including seven cases complicated by aspergillosis.Clinical manifestation,imaging and surgery of these patients were analyzed.Literature focusing on PS complicated by aspergillosis in pubmed data base was reviewed.Results In these seven patients,four cases were male,and three cases were female.Age at diagnosis ranged from 29 to 58 years old.The interval from onset to definite diagnosis ranged from two weeks to 20 years.Clinical symptoms included productive cough in seven cases,hemoptysis in three cases,chest pain in two cases,and fever in one case.All cases were intralobar PS with four in the left lower lobe and three in the right lower lobe.Consolidation in chest CT was noted in six cases.Cavitation was positive in three cases.Surgery of lung lobe resection was performed in all patients.Aberrant arteries were found during operation with the origin from aortic artery in four cases,phrenic artery in two cases,and intercostal artery in one case.Aspergillosis was diagnosed by pathology in six cases and by lung tissue culture in one case.Conclusions PS complicated by aspergillosis is extremely rare,but the trend of an increase in recent years has been noted.Strict and cautious examinations for microorganisms and pathology will help find relatively insidious aspergillosis.

Increases in diagnostic frequency of breast ductal carcinoma in situ(DCIS) have followed the introduction of mammographic screening in past years.It is very important to distinguish the clinical syndrome of DCIS.The management of surgery for DCIS includes mastectomy,lumpectomy plus radiotherapy and lumpectomy alone; axillary lymph node dissection(ALND) in DCIS has not been recommended and sentinel lymph node biopsy(SLNB) is still controversial; adjuvant radiotherapy for ipsilateral whole breast and endocrine treatment can reduce local recurrence,prevent second primary breast tumor,preclude regional and distant metastasis.But whatever we take towards the DCIS above,there is little disturbance to DCIS' s inherent prognosis.Doctors must pay enough attention to this point.

Objective To explore the effect of atorvastatin combined with aspirin on therapeutic efficacy of acute cerebral infarction, and on the changes in neurologic impairment, blood lipids and carotid plaque, et al. Methods The 80 patients with acute cerebral infarction were randomly divided into the treatment group (n=40) and the control group (n = 40)who took atorvastatin combined with aspirin and aspirin alone respectively. The defect degree of nerve function, curative effect, changes of blood lipids and cervical vascular ultrasound parameters were compared between the two groups, and they were followed up for 6 months to observe the recurrence of cerebral infarction.Results Compared with the control group, the levels of TG, TC, HDL-C and LDL-C, internal diameter of common carotid artery, size of plaque, drag index, pulsatility index and neurological function deficit scale (NFDS) were significantly lower in treatment group [(1.36 ± 0.33) mmol/L vs.(1.77±0.80) mmol/L, (5.21±0.32) mmol/L vs. (5.80±0.37) mmol/L, (1.20±0.10) mmol/L vs. (1.43±0.16) mmol/L, (1.31±0.37) mmol/L vs. (1.57±0.39) mmol/L, (6.43±0.71) mm vs. (6.67±0.47) mm, (40.39±8.94) mm3 vs. (54.26±8.25) mm3, (0.70±0.06) vs. (0.82±0.08), (2.12±0.37) vs. (2.18±0.54), (10.24±3.31) scores vs. (14.69±3.23) scores, all P＜0.05 or ＜0.01]. The intima-media thickness and peak systolic velocity of carotid artery were higher in treatment group than in control group [(1.66±0.50) mm vs. (1.50±0.68) mm, (71.34±15.01)an/s vs. (68.97 ± 18.21 ) an/s, both P＜ 0.01]. The total effective rate was higher in treatment group than in control group (92.5% vs. 75.0%, P＜0.05), and there were no recurrence of cerebral infarction within 6 months. Conclusions Atorvastatin combined with aspirin in treatment of acute cerebral infarction is beneficial to resume neurological function, improve prognosis, decrease the volume of carotid atherosclerotic plaque, stabilize plaque and reduce blood lipids, and it play an positive action in the intervention of cerebral infarction recurrence, and it can be used to treatment acute cerebral infarction as combination therapy.

Objective To evaluate the treatment of acne vulgaris with acupuncture by different methods of point selection.Methods 51 cases of acne vulgaris were randomly recruited into local point selection group,distal point selection group and combination of local and distal point selection group.10 cases of healthy people were recruited for normal control group.Serum arachidonic acid (AA),free testosterone (FT),and sex hormone binding globulin (SHBG) levels were observed in all treatment groups.Results After the treatment,serum AA was (20.56±5.28)μg/L,(18.86±5.70) μg/L and (14.62±3.06) μg/L,while SHBG was (333.31±87.96) nmol/L,(332.02±87.82) nmol/L and (273.02±61.74) nmol/L respectively in local point selection group,distal point selection group and combination of local and distal point selection group,both showing no significant difference than the normal control group (P＞0.05).There was no significant difference in FT value between the combination of local and distal point selection group (5.62± 1.98) nmol/L and the normal control group (P＞0.05).The decrease of AA in the combination of local and distal point selection group was between than the local point selection group (P＜0.01).Conclusion Acupuncture can effectively improve the level of inflammatory factors and androgen of the acne vulgaris.Different methods of point selection of acupuncture on the improvement of some indicators were quite different,which laid the foundation for the best compatibility of acupuncture treatment in acne vulgaris.
