A polyimide coated stir bar for sorptive extraction (SBSE) was prepared by immersion precipitation method, and evaluated by using 5 phenols and chlorinated phenols as model samples. The extraction efficiency of the prepared stir bar was the highest compared with commercial extraction phases of SBSE. Experimental parameters including stir speed, ionic strength, extraction temperature, extraction time, desorption temperature and time were optimized. Under the optimal conditions such as 100 mL of sample, 30 g of NaCl, extraction time of 30 min, stirring speed of 800 r/ min and at 25℃, the target compounds were recovered by thermal desorption at 300℃ for 4 min, more than two orders of magnitude of linearity was obtained (R≥0. 9995), LOQs (S/ N=10) were 0. 028-0. 123 μg/ L, and RSDs were in the range of 1. 6% -9. 7% . The polyimide SBSE coupled with gas chromatography-mass spectrometry was applied to the extraction/ enrichment and analysis of phenols in real samples, including tap water, sea water, and waste water. It was found that the polyimide SBSE showed high selectivity towards polar compounds and high thermostability up to 350℃.

Objective To analyse the effect of octreotide combined with compound coenzyme on Th17/CD4 +CD25 +Foxp3 + regulatory T cells imbalance in patients with purulent appendicitis.Methods 150 patients with acute suppurative appendicitis were randomly divided into experimental group and control group, 75 cases in each group.Patients of two groups underwent appendicitis laparoscopic resection, then the control group were given conventional treatment and experimental group were given subcutaneous injection of octreotide on the basis of conventional treatment.Th17, CD4 +CD25 +Foxp3 +regulation T cells ( Treg) , and Th17 /Treg balance were analyzed.ResuIts Compared with control group, Th17/Treg imbalance of experimental group recovered better: the proportion of Th17, Treg, and Th17/Treg ratio decreased (P<0.05); the expression levels of related transcription factor, RORγt and Foxp3 mRNA decreased (P<0.05); serum cytokine (IL-4, IL-6, IL-10, IL-17, IL-23 and TGF beta) and C-reactive protein (CRP) content decreased (P<0.05);serum interferon gamma (IFN-gamma) content increased (P<0.05).ConcIusion Octreotide combined with compound coenzyme could correct Th17/Treg imbalance in suppurative appendicitis patients, improve the immune function of patients and affect the prognosis of patients.

This study investigated the ability of millimeter-wave (MMW) to promote the differentiation of bone marrow stromal cells (BMSCs) into cells with a neural phenotype. The BMSCs were primarily cultured. At passage 3, the cells were induced by beta-mercaptoethanol (BME) in combination with MMW or BME alone. The expressions of nucleostemin (NS) and neuron-specific enolase (NSE) were detected by immunofluorescent staining and Western blotting respectively to identify the differentiation. The untreated BMSCs predominately expressed NS. After induced by BME and MMW, the BMSCs exhibited a dramatic decrease in NS expression and increase in NSE expression. The differentiation rate of the cells treated with BME and MMW in combination was significantly higher than that of the cells treated with BME alone (P<0.05). It was concluded that MMW exposure enhanced the inducing effect of BME on the differentiation of BMSCs into cells with a neural phenotype.

Objective: To observe the clinical effect and infra-red thermogram changes for acute lumbar sprain. Methods: All 295 cases with acute lumbar sprain were randomly divided into an electroacupuncture group (147 cases) and medication group (148 cases). The cases in electroacupuncture group were treated by needling Houxi (SI 3), whereas those in the medication group were treated with Meloxicam tablet. The infra-red thermogram was observed before and after treatment. Results: The recovery and effective rates in the electroacupuncture group were 71.4% and 93.9%, whereas the rates in the medication groups were 42.6% and 87.2% (P＜0.01). The temperature differences via the thermogram in the electroacupuncture and medication groups were 2.52℃ and 0.80℃ (P＜0.01), indicating a significant difference.Conclusion: Both electroacupuncture and medication could obtain significant effect for acute lumbar sprain; however, electroacupuncture obtained a better overall effect and a more substantial temperature-raising effect in the thermogram than medication.

Objective To investigate the clinical efficacy of neck point Bailao injection as main therapy plus acupuncture for cervical spondylotic radiculopathy. Method Two hundred patients with cervical spondylotic radiculopathy were randomly allocated to treatment (neck point Bailao injection as main therapy plus acupuncture) and control (oral administration of Western medicines, e.g. nonsteroid diclofenac sodium as a main drug and meanwhile, mecobalamin tablets) groups. The therapeutic effects and pre-/post-treatment changes in clinical symptoms and signs, TCM syndrome, pains and numbness were observed in the two groups. Result The total efficacy rate was 86.0%in the treatment group and 75.0%in the control group;there was a statistically significant difference between the two groups (P<0.05). The total efficacy rate was higher in the treatment group than in the control group. There were statistically significant differences in pre-/post-treatment clinical symptom and sign score difference values between the treatment and control groups (P<0.01), indicating that the symptoms and signs improved more in the treatment group than in control group. Conclusion Both treatments can improve the clinical symptoms and signs and relieve pains in cervical spondylotic radiculopathy, but neck point Bailao injection as main therapy plus acupuncture is more effective than oral administration of Western medicines.

This study explored the possibility that the components in melanoma cytoplasm induce murine BMSCs transformation and expression of Melan-A by morphologically observing the changes of BMSCs and immunocytochemically detecting Melan-A in the cells after culturing BMSCs in medium containing melanoma cytoplasm components (MCC). MCC of B16 melanoma cells was prepared and BMSCs were cultured and induced by adding the MCC into culture medium. The cells were morphologically observed and Melan-A was immunohistochemically detected to confirm BMSCs transformation. MCC-induced BMSCs underwent morphological changes. A number of melanin granules appeared in the cytoplasm of the cells and some were released into surrounding areas. Several cells that might come from one cell formed a cluster, and their granules, together with those secreted by other induced BMSCs, formed a so-called "sphere-formed structure". The induced BMSCs expressed Melan-A. We are led to conclude that there might be some factors in the cytoplasm of melanoma cells that might induce BMSCs transformation toward melanogenic cell, or even melanoma.

OBJECTIVE:To standardize the ward rescue and essential drugs quality management in wards,and reduce the med-ication risk of patients. METHODS:Failure mode and effect analysis(FMEA)was used to analyze the inspection items and failure modes of quality management of ward rescue and essential drugs. According to scoring the possibility,severity and detectability de-gree of the failure modes and calculating the risk priority number(RPN),failure modes that should be given priority improvement were quantified and determined,improvement measures were developed and conducted,and management effects were evaluated af-ter 6 months. RESULTS:12 failure modes were determined,including the residue treatment of narcotic and the first-class psycho-tropic drugs was not recorded,drug storage temperature was not up to standard and drug expired,etc. Improving related systems, enhancing the inspection management,cold chain management,daily management and other measures were implemented and con-ducted. After 6 months,the top 3 items with the highest RPNs were dropped from 320,240,216 score to 16,16,27 scores,re-spectively,all in a relatively low risk area. Numbers of failure mode event were dropped from 1869 to 218,dropping by 88.3%. CONCLUSIONS:According to qualifying the failure modes in ward rescue and essential drugs quality management by using FMEA in our hospital,the management items with the highest risk has determined and improved,the medication risk of patients has significantly reduced.

One course of treatment consisted of 10 days. Result Cancer pain was relieved, analgesic dosage decreased, adverse reactions to analgesics reduced and quality of life raised significantly in the treatment group compared with the control group. Conclusion Qin’s scalp eight-needle acupuncture is effective in treating cancer pain.
