Objective:To understand the willingness of breast cancer patients to participate in lymphatic reflux training and management after surgery, and analyze its influencing factors.Methods:A total of 157 postoperative patients with breast cancer were selected by convenience sampling method. The investigation tools included general information questionnaire and lymphedema health belief questionnaire.Results:64.3% (101/157) of the patients were willing to participate in lymphatic reflux training and management. Logistic regression analysis showed that ethnic group ( OR=0.06, 95% CI 0.01-0.68), divorce ( OR=0.08, 95% CI 0.01-0.89), benefit cognition ( OR=12.41, 95% CI 4.26-36.19), obstacle cognition ( OR=3.83, 95% CI 1.48-9.91), behavioral clues ( OR=3.72, 95% CI 1.51-9.20) were significant influencing factors of parents' willness of participating in lymphatic reflux training and management( P<0.05). Conclusion:The willingness of patients to participate in lymphatic reflux training and management is at a medium level, which was influenced by ethnic group, marital status, health belief of benefits cognition, obstacle cognition and behavioral clues. Attention should be paid to the implementation during health education for the prevention of lymphedema, and patient′s willness of participating in lymphatic reflux training and management should be improved.

Objective:To establish a BALB/c mouse model of Echinococcus granulosus allergy and investigate the role of lymphocyte subsets in Echinococcus granulosus-induced sensitization. Methods:Echinococcus granulosus was isolated from the liver of sheep naturally infected with Echinococcus granulosus and cultured for 40 d. BALB/c mice were intraperitoneally injected with 50 microcapsules and sensitized by intraperitoneal injection of 0.1 ml/10 g of larval Echinococcus granulosus capsule six months after infection. According to the symptom scores 1 h after sensitization, these mice were divided into two groups: non-sensitized group ( n=6) and sensitized group ( n=6). The mice ( n=6) in control group were injected with sterile saline. Blood sample was collected from the angular vein of each mouse. Flow cytometry was used to detect B cells, NK cells and CD3 +/CD4 +/CD8 + T cells. Cytometric bead array was used to measure IL-4, IL-6 and IL-13. Results:The percentage of B cells was significantly higher in the non-sensitized group than in the control group ( P<0.001), but no significant difference was observed between the sensitized group and the control group. Compared with the non-sensitized group, the percentage of B cells in the sensitized group decreased significantly ( P<0.01). Compared with the control group, the percentages of NK cells in the non-sensitized group and the sensitized group decreased significantly ( P<0.001 and P<0.01). Compared with the non-sensitized group, the percentage of NK cells in the sensitized group increased significantly ( P<0.05). Compared with the control group, the percentage of CD3 + and CD4 + T cells in the non-sensitized group decreased significantly ( P<0.05), while the percentage of CD8 + T cells increased significantly ( P<0.01). Compared with the control group, the percentage of CD3 + and CD4 + T cells in the sensitized group increased significantly ( P<0.05 and P<0.001), while no significant change in the percentage of CD8 + T cells was detected. Compared with the non-sensitized group, the percentage of CD3 + and CD4 + T cells in the sensitized group increased significantly ( P<0.05), while the percentage of CD8 + T cells decreased significantly ( P<0.01). The levels of IL-4, IL-6 and IL-13 were significantly higher in the non-sensitized group than in the control group ( P<0.001). Compared with the control group, the sensitized group showed increased IL-4 ( P>0.05), significantly increased IL-6 ( P<0.01) and decreased IL-13 ( P>0.05). The levels of IL-4, IL-6 and IL-13 in the sensitized group were significantly lower than those in the non-sensitized group ( P<0.001). Conclusions:The BALB/c mouse model of allergy induced by larval Echinococcus granulosus was successfully established. This study proved that the humoral immune response induced by Th2 cells played an important role in Echinococcus granulosus-induced sensitization, which provides an important scientific basis for establishing a prevention and treatment strategy for patients with anaphylactic shock caused by extravasation of Echinococcus granulosus fluid.

OBJECTIVE:To study invalid medical order warned by Prescription automatic screening system (PASS),and to improve rational drug use monitoring. METHODS:The infusion medical order warned with black light,red light and orange light by PASS were extracted from Pharmacy intravenous admixture services(PIVAS)of our hospital during Oct. to Dec. 2014. Invalid warning items were analyzed statistically in respect of warning level,problem types and reasons. RESULTS & CONCLUSIONS:There are 3 392 warnings items,468 were invalid (13.80%) which include 10 items by black light,219 items by red light and 239 items by orange light;by problem types,there are 218 items of overdose and 136 items of repeated treatment,etc. The main causes of invalid warning include 191 items caused by wrong system prompt,126 items by incomplete system information,143 items by insufficient auditing standards,etc. There are still some defects of invalid warning in practical application of PASS. It is suggested that user and developer add the function of self-defined drug list or user-defined system data by,and unify auditing stan-dards of rational drug use,etc.,so as to timely update the system information,and improve the accuracy of software system moni-toring and warning function.

Objective To create new tetraploid resource of Dioscorea zingiberensis in the hope of potential breeding materials with high yield and high level of diosgenin. Methods Callus with tiny green buds were directly soaked in colchicine solution or cultured in medium plus with colchicine to prohibit the isolation of chromosomes and induce tetraploid mutants. Results Tetraploids were achieved successfully. The most efficient treatment for inducing tetraploid was soaking the tiny buds in 1?103 mg/L colchicine solution for 24 h, the inducing rate could be up to 35. 2%. The induced tetraploids exhibited notable difference with common wild type (diploids) in morphology, physiology, and microscopic structure. ConclusionThe tetraploid plants show the advantages of gigantic size and vigorous growth. Thus, the established technique system to induce tetraploid from tissue cultured callus would provide an efficient alternative pathway for medicinal plants of Dioscorea L. breeding.

Objective To investigate the inhibitory effect of Lycium barbarum polysaccharide ( LBP) on the tumor growth and metastasis in MMTV?PyMT mouse model of breast cancer. Methods The population of MMTV?PyMT trans?genic mice was expanded and identified. 8?week old MMTV?PyMT?positive female mice were randomly divided into LBP group and control group, 8 mice in each group. The mice of LBP group were given LBP treatment (50 mg/kg, i. p. ), and the control group was given normal saline in the same volume, once every 2 days for 4 weeks. The tumor size was measured every two days. The mice were killed at 4 weeks after treatment, the lungs were removed and fixed in Bouin′s solution to observe the number of metastatic nodules, and tumor tissues were used for immunohistochemical examination of tumor cell proliferation and vascular density. Results The tumor formation rate was 100% in the MMTV?PyMT?positive mice. The tumor weight of LBP group was 4?208 ± 0?4463 g, significantly lower than the 6?477g ± 0?3724 g in the control group (P<0?005). The number of pulmonary nodules of the LBP group was 12 ± 1?155, significantly less than that of the control group (20 ± 2?745) (P<0?05). The immunohistochemical examination using Ki67 and CD31 staining showed that tumor cell proliferation and microvessel density of the LBP group were significantly less than the NS group. Conclusions LBP inhibits breast cancer growth and metastasis through the inhibitory effect on tumor growth and metastasis, inhibition of tumor cell proliferation and angiogenesis in MMTV?PyMT mice. These mice can be used as an ideal model for studies on antitu?mor drug development for the treatment of breast cancer lung metastasis.

Objective To evaluate the correlations between the cerebral hemodynamic changes of severe acute encephalopathy with the clinical features from emergency periods to stable periods and the value of transcranial Doppler ultrasonography( TCD)in cerebral function assess. Methods Thirty patients with acute brain diseases by assisted mechanical ventilator from Jun 2014 to May 2015 in PICU were included and followed up to Nov 2015,then grouped by Glasgow Coma Scale( GCS),MRI,prognosis( mental sequelae after half a year). Each subject was examined through the temporal bone window by TCD at emergency peri-ods and stable periods. The systolic cerebral blood flow velocity( sCBFV),and pulsatility index( PI)of bilat-eral middle cerebral artery( MCA),anterior cerebral artery,posterior cerebral artery were analyzed. Multivari-ant analysis of variance,repeated measures analysis of variance was conducted to compare sCBFV and PI of MCA among groups in different clinical periods. The variants included sex,disease diagnosis,prognosis, MRI,GCS,and the first abnormal TCD. The variation within groups was tested via a Hotelling T2 test. All sCBFV and PI of each artery and the D-value of sCBFV between the different periods were compared accord-ing to the prognosis groups. Results (1)Five patients could be lateralized,and their lateralization of MRI focus was consistent with the abnormal sides of sCBFV in the stable periods.(2)The D-value of sCBFV in left MCA between the different periods in the poor prognosis group was significantly higher than that in the good prognosis group[(71. 93 ± 58. 21)cm/s vs.(33. 20 ± 30. 23)cm/s,t = -2. 287,P =0. 033].(3) Multivariant analysis of variance showed that GCS classification and disease diagnosis were significantly cor-related with the cerebral hemodynamic changes respectively(P =0. 042,0. 005,respectively).(4)sCBFV and PI of left MCA reduced significantly in the stable periods than those in the emergency periods( P =0. 002,0. 003,respectivly). Conclusion The cerebral hemodynamic changes by TCD from emergency peri-ods to stable periods are consistent with the clinical status,dynamic evaluation by TCD may facilitate the evaluation of brain dysfunction in the severe acute encephalopathy.

OBJECTIVE To evaluate the clinical feature and surgical treatment of large nasopharyngeal angiofibromas with intracranial orcavernous sinus extension.METHODS A total of 16 male patients were collected with a age ranged from 11 to 35 years(mean,17.21 years).All patients underwent resection of nasopharyngeal angiofibromas with intracranial or cavernous sinus extension.The procedure included lateral rhinotomy,craniofacial combined approach,median labiomandibulotomy combined with a trans-palatal,transmaxillary approach and middle face degloving approach.RESULTS Sixteen cases received 28 procedures.Seven patients had no recurrence but 9 patients had recurrence at least once.Twenty eight procedures include 11 times lateral rhinotomy,6 times craniofacial combined approach,2 times frontotemporal approach,4 times transpalatal approach,2 transmaxillary approach,1 median labiomandibulotomy combined with a trans-palatal and 2 times middle face degloving approaches.CONCLUSION Radical operative resection is the main treatment method for nasopharyngeal angiofibroma with intracranial or cavernous sinus extension.The first operation recurrence rate is 8/15(53.0%) and sphenoid tumor residual may often be ignored in the operation and it is the main site of tumor recurrence.Craniofacial,median labiomandibulotomy combined with a trans-palatal and middle face degloving approaches were the best choices for large nasopharyngeal angio fi broma with intracranial or cavernous sinus extension.

Objective: To observe the effect of Tuina (Chinese therapeutic massage) on creatine kinase (CK), mitochondrial Ca2+ concentration, and ultrastructure of skeletal muscle in delayed onset muscle soreness (DOMS) model rats.Methods: A total of 130 healthy male Sprague-Dawley rats were randomly divided into a blank group, an exercise control group, a pre-exercise Tuina group, and a post-exercise Tuina group. According to the time points for sample collection, the exercise control group was divided into a 0 h exercise control group, a 24 h exercise control group, a 48 h exercise control group, and a 72 h exercise control group; the pre-exercise Tuina group was further divided into a 0 h pre-exercise Tuina group, a 24 h pre-exercise Tuina group, a 48 h pre-exercise Tuina group, and a 72 h pre-exercise Tuina group; and the post-exercise Tuina group was divided into a 0 h post-exercise Tuina group, a 24 h post-exercise Tuina group, a 48 h post-exercise Tuina group, and a 72 h post-exercise Tuina group. Rats in all groups except for the blank group received DOMS modeling. Professionals performed Nie-Pinching manipulation and finger Nian-Twisting manipulation on the lower limbs of the rats. The samples were collected at 0 h, 24 h, 48 h, or 72 h after exhaustive exercise for each pre-exercise Tuina group. The samples were collected at 0 h, 24 h, 48 h, or 72 h after Tuina for each post-exercise Tuina group. The changes in serum CK, skeletal muscle mitochondrial Ca2+ concentration, and Ca2+-adenosine triphosphatase (ATPase) were determined. The ultrastructure changes of skeletal muscles in each group were observed by a transmission electron microscope. Results: The electron microscope showed that compared with the exercise control group, the skeletal muscle structures of the pre-exercise Tuina group and the post-exercise Tuina group were significantly improved, and the overall performance of skeletal muscle in the pre-exercise Tuina group was more similar to that of the blank group. The level of serum CK in the pre-exercise Tuina group and the post-exercise Tuina group was significantly lower than that in the exercise control group (P<0.01). The Ca2+ concentration of skeletal muscle in the 24 h, 48 h, and 72 h pre-exercise Tuina groups was lower than that in the post-exercise Tuina group at the same time point (P<0.01). The Ca2+-ATPase concentration of skeletal muscle in the 24 h and 72 h pre-exercise Tuina groups was lower than that in the post-exercise Tuina group at the same time point (P<0.05).Conclusion: Tuina effectively prevents muscle damage caused by heavy exercise and long-term exercise, which may be related to the increase of skeletal muscle Ca2+-ATPase activity and mitochondrial Ca2+ transport.

OBJECTIVETo evaluate the possibility of vaginal hysterectomy for patients with moderately enlarged uterus of benign lesions.

METHODSOne hundred and seventeen women with benign uterine diseases underwent vaginal hysterectomy. These patients were divided into two groups according to uterine weight. Group I contained 60 patients with uterine enlargement to a weight of 200 to 750 g, and group II contained 57 patients with uterine weight of less than 200 g. Uterine morcellation was performed in some cases. The perioperative data in both groups were analyzed.

RESULTSIn group I, 59 cases underwent transvaginal hysterectomy successfully, except 1 case converted to abdominal operation and the uterine morcellation was performed in 21 women. In group II, all patients successfully underwent transvaginal hysterectomy without any assistance of special technique. The mean uterine weight of group I was significantly heavier than that of group II (280.18 +/- 100.40 g vs 146.48 +/- 35.19 g). The mean operating time was significantly longer for group I than that for group II (83.93 +/- 26.26 minutes vs 35.22 +/- 20.55 minutes). There were no significant differences in blood loss and complications between group I and group II. There was no injury of urinary bladder or rectum, and no vaginal vault infection.

CONCLUSIONSVaginal hysterectomy of moderately enlarged uterus can be safely and effectively performed by experienced operators. In some cases, in order to reduce the uterine volume, uterine morcellation should be used to shorten operative time, reduce the bleeding, and lower the postoperative complications.

Objective To investigate the risk factors for intracranial infection after external ventricular drainage and provide basis for preventing and controlling the drainage-associated intracranial infection. Metheds the clinical data from three hundred sixty-seven cases of ventricular hemorrhage patients were retrospectively analyzed, using Logis?tic regression to screen risk factors of intracranial infection after external ventricular drainage. Results There were 29 cases with intracranial infection and infection rate was 8.19%, 8.04% and 7.32% at ventricle drainage tube indwelling 1-week group, 2-week group and 3 week-group, respectively. Glasgow coma score (GCS) [OR= 2. 569 CI (1.792 3.378) %, P< 0.05), urokinase perfusion (OR= 2.897, 95%CI (1.297 5.061), P< 0.05), cerebrospinal fluid sampling (OR= 3.399, 95%CI (2.705 4.175), P< 0.01] and comorbidities [OR= 3.751, 95%CI (2.032 5.371), P< 0.01] were risk factors for ventricle drainage operation. Conclusion Ventricle drainage tube indwelling 3 weeks is safe. Less use of urokinase perfusion and cerebrospinal fluid sampling and active treatment of comorbidities diseases can reduce the intra?cranial infection incidence of external ventricular drainage after Intraventricular hemorrhage .
