The content of Linaiool was the highest which was 15.17%, 28.85% and 31.88% in L. macranthoides Hands-Mazz. from Longhui County, Xupu County and Xinning County.

Objective To investigate the role of transforming growth factors(TGF-?1 and ?2) in the pathogenesis of scleroderma(SD). Methods The mRNA expression of TGF-?1 and ?2 in the skin lesions from 17 patients with SD and skin from 10 normal controls were detected with in situ RT-PCR technique. Results A higher positive rate and stronger expression of TGF-?1 mRNA in SD skin lesions were seen, compared with those in controls(P0.05).The higher positive rate and stronger expression of TGF-?1 mRNA than TGF-?2 mRNA in SD were seen(P

Objective :To determine the weight coefficient and optimize the steaming technology of decoction pieces of Scrophularia ningpoensis (SN). Methods The contents of harpagide, harpagoside, aucubin, acteoside, angoroside C, and cinnamic acid were simultaneously determined by HPLC. The weight coefficient of each component was evaluated by AHP-entropy (analyitc hierarchy process) method. With composite score as index, D-optimal response surface methodology was adopted to investigate the effects of soaking time, steaming time, and drying temperature on the quality of processed products and optimize the processing technology of decoction pieces of SN. Results :Optimal processing parameters were as follows: soaking time was 15.63 min, steaming time was 85 min, drying temperature was 60 ℃, and the synthetical mark was 97.20. Considering the actual situation, the optimum processing technology of SN was obtained by fine-turning the soaking time. The soaking time was 15 min, the steaming time was 85 min, and the drying temperature was 60 ℃. Also, the synthetical mark were 98.53, 99.39, 98.86, and its RSD was 0.47% through the obtained conditions in parallel with three batches of samples. Conclusion: The optimized steaming technology is simple and feasible, which can provide a reference for the steaming of decoction pieces of SN. The method established to simultaneously determine the contents of six components in decoction pieces of SN is rapid and reliable for controlling the quality of decoction pieces of SN.

Forty five patients with acute cerebral infarction were randomized to two groups: in treatment group patients received local subhypothermia and conventional therapy, in control group patients received conventional therapy only. Clinical outcome was assessed by the National Institutes of Health Stroke Scale (NIHSS) on admission and at 7, 14 and 30 d after treatment. Serum neuron specific enolase (NSE), nitrogen monoxide ( NO ) , superoxide dismutase (SOD), interleukin-6 (IL-6 ) and intercellular adhesion molecule-1 (ICAM-1) were detected on admission and at 7,14 d after treatment The study showed that NIHSS scores of treatment group on 14, 30 d were lower than those of control group ( P ＜ 0. 05 ). Serum NSE, NO, IL-6 and ICAM-1 levels significantly decrease; while serum SOD levels increased (P ＜ 0. 05). In conclusion, local subhypothermia therapy can inhibit inflammatory reaction, reduce oxygen free radical formation and improve neurological function in patients with acute cerebral infarction.

ObjectiveTo explore the screening and therapeutic efficacy of primary carnitine deficiency (PCD) in newborns and mothers.Methods164245 newborns and suspected mothers were investigated for PCD by tandem mass spectrometry (MS/MS).The overall epidemiology,prognosis,and follow-up of the screening program were investigated.ResultsTotally 55 suspected cases were identified at the primary screening stage.Four newborns and three mothers were confirmed as cases of PCD.The incidence rate of newborns was 1 ∶ 40076.All the patients showed normal growth and development during the follow-up.Blood free carnitine level was raised in all three mothers after treatment.ConclusionsScreening for PCD with MS/MS in newborns may represent a valuable procedure in preventive medicine by enabling early diagnosis and treatment before the onset of symptoms.This protocol is also highly efficient and applicable in diagnosis of mothers with PCD.

Immune checkpoint inhibitors are members of a class of immune-suppressive molecules that regulate the strength and range of immune responses to avoid normal tissue damage. However, immune checkpoint activity can be stimulated by tumors to es-cape immune surveillance. To elicit anti-tumor effects, immune checkpoint inhibitors can promote the activation of T cells by blocking immune checkpoint proteins. Therefore, these inhibitors can be efficiently and safely used to treat solid tumors. Although the clinical usage of these inhibitors is in the initial stage, they have exhibited good efficacy and safety in lymphoma treatment. This review sum-marizes the biological activities of CTLA-4, PD-1, and PD-L1 and the application of antibodies as drugs for lymphoma treatment.

OBJECTIVETo evaluate the therapeutic effects of percutaneous kyphoplasty (PKP) for the treatment of osteoporotic vertebral compression fracture (OVCF) with degenerative scoliosis.

METHODSFrom March 2009 to March 2014,121 patients undergoing PKP for the treatment of osteoporotic vertebral compression fracture (OVCF) with degenerative scoliosis were retrospective analyzed. There were 41 males and 80 females,ranging in age from 56 to 92 years with an average of 73.2 years. Preoperative and postoperative 3 d respectively pain visual analogue scale (visual analogue score, VAS) and Oswestry Disability Index assessed pain and functional recovery of patients and preoperative and postoperative 3 d lumbar lordosis, scoliosis Cobb angle were analyzed.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 24 months, with a mean time of 11 months. All the patients achieved success in operation without serious complications. The operation time ranged from 30 to 65 min with an average of 42.2 min. Local leakage of bone cement was not found in canal. The VAS and Oswestry Disability Index at the 3rd day after operation decreased significantly compared with those of the preoperative (P < 0.05), and the lumbar lordosis and scoliosis Cobb angle also improved significantly compared with those of the preoperative (P < 0.05).

CONCLUSIONPercutaneous kyphoplasty (PKP) for the treatment of thoracolumbar scoliosis osteoporotic fracture can significantly improve patients spinal deformity, pain relief, which is worth of recommending.
