Objective To explore the incidence rate, total incidence numbers and possible impacting factors of non-motor symptoms (NMSs) in Parkinson's disease (PD). Methods The NMS questionnaire (NMS Quest) was used to investigate 131 out-patients diagnosed with PD, and the prevalence of each item, the total NMS numbers and their relationships with clinical features were assessed. Results All of the patients, who were distributed in every stage of PD, had NMSs and each case with 11 items on average. Autonomic symptoms such as nocturia and constipation were the most frequent ones. The patients over 65 versus less than 65 years old had a higher prevalence in a number of items such as olfactory disturbance, dysphagia and constipation. At the same time, the rigidity subtype patients had a higher prevalence in depression items than the tremor subtype ones.The total number of NMS was positively correlated with course of disease, age, UPDRS score and Hoehn & Yahr (H&Y) stage. Conclusions NMSs are common among PD patients. While the prevalence of each item may vary with different clinical features, the total number of NMS is increased with the severity of PD. More attention should be paid to the diagnosis and rational treatment of the NMSs.

OBJECTIVE: To develop a method for determining the concentration of lamivudine in placental perfusate by employing ultra fast liquid chromatography with tandem mass spectrometry (UFLC-MS/MS). METHODS: Famotidine was used as the internal standard. After protein precipitation with acetonitrile, the chromatography was performed on a Shim-pack XR-ODS II C18 column (2.0 mm × 75 mm, 2.2 μm) with mobile phase consisting of methanol and 10 mmol · L-1 ammonium acetate, gradient elution was used, and the flow rate was 0.4 mL · min-1. Tandem mass spectrometric detection was conducted by using multiple reaction monitoring (MRM) in positive ionization mode with an electrospray ionization interface. RESULTS: The calibration curve of lamivudine was linear in the range of 1-2500 ng · mL-1. The intra- and inter-batch RSDs were less than 10%. The method recovery was more than 72%. CONCLUSION: The method is rapid and accurate, which is suitable for the determination of lamivudine in placental perfusate.

The average stage in hospital was 11±7 days. The following-up of 98 patients showed that 82 patients were excellent, 16 patients good and only 1 patients not up to standard.Conclusion Arthroscopic surgery has following advantages such as less invasive surgery, shorter stage in hospital, good curative effect in the near future.

Objective To design a kind of aseptic drainage device with safe practice and accurate measurement for clinical nurses. Methods The experiment group included 63 cases using drainage device with accurate measurement,and control group included 63 cases using disposal drainage bag with scale of visual measurement.The accuracy of drainage liquid measurement was compared between two groups,and bacterial culture was made for the drainage liquid of two groups.Results The measurement error of experiment group and control group was(3.31±1.8)mL and(56.0±5.8)mL,respectively.The difference was significant(t=-4.593,P<0.01).The bacterial culture results showed no obvious difference between two groups(positive rate were 15.9%vs 17.5%,χ2=0.057,P>0.05). Conclusion The accurately measured aseptic drainage device is convenient for nurses to practice in clinics,and its application can reduce workload of nurses and decrease the occurrence of pollution.

Objective To investigate the change of HepG2 liver tumor perfusion after microbubble enhanced ultrasound cavitation treatment and observe the related pathological injury.Methods Twenty eight Balb/c(nu/nu) nude mice transplanted subcutaneous HepG2 tumor were divided into three groups randomly,including the microbubble enhanced ultrasound cavitation group,the ultrasound group and the sham group.Microbubble enhanced ultrasound cavitation treatment was performed by 0.1 ml microbubbles intravenous injection combined with pulse ultrasound emission in experimental group,while in control groups only ultrasound exposure or microbubble injection were applied.The perfusion of tumors was imaged using contrast-enhanced ultrasonography before and after treatments.Time-intensity curve and peak intensity were analyzed.The tumors were then harvested for histological examination.Results The perfusion of HepG2 tumors almost vanished immediately after treatment in experimental group,with the peak intensity reduced from (26.9 ± 10.9)％ to(8.2 ± 5.8)％ (P ＜0.05).There was no significant changes before and after treatments (P ＞ 0.05) in the two control groups.Histological findings were disruption of the endothelia,significant hemorrhage and increased intercellular fluid.Conclusions Microbubble-enhanced ultrasound cavitation can significantly reduce tumor blood perfusion and disrupt tumor vascularture.This new ultrasound therapy can potentially become a new physical anti-angiogenetic therapy for liver tumor.

Objective To investigate the effect of Shugan-Yishen formula on Tamoxifen-resistant MCF-7 cell line(LCC9) through HER2-ERK/MAPK-ERα pathway. Methods Four serums were prepared with the method of serum pharmacology:the serum of Shugan-Yishen formula, Shugan-Yishen formula plus Tamoxifen(TAM), blank and TAM alone. After LCC-9 cells were affected in the above-mentioed serums in vitro, the inhibition rate and the level of mRNA as well as the protein expression of HER2, ERα, ERK/MAPK, p-ERK/MAPK were detected. Results MTT showed that TAM alone group、Shugan-Yishen formula group and the Shugan-Yishen formula plus TAM group had higher inhibition rates at 48th hour, the inhibition rates was(6.61±0.129)%, (47.43±2.24)%, (54.19±3.364)%, compared to the blank group, Shugan-Yishen formula group and the Shugan-Yishen formula plus TAM group had a stronger inhibition on LCC9 at 48th hour (P<0.05), and the combination group was better than Shugan-Yishen formula alone(P<0.05), there was no difference between TAM group compared to the blank group(P>0.05). RT-PCR result showed that compared to the blank group, the expression levels of ESR1 mRNA of group of Shugan Yishen formula plus TAM werehigher by and large at 48th hour (P<0.05), the expression of ESR1 mRNA was(2.282±0.185);and the levels of ERBB2, MAPK3 mRNAwere lower(P<0.05), which levels were(0.71±0.095), (0.336±0.058). Western blotting result showed that Shugan-Yishen Formula plus TAM group could markedly decrease the expression of HER2, p-ERK/MAPK of LCC9 at 48th hour (P<0.05), which the expressions were(0.708± 0.072), (0.228±0.034), and the expression of ER-αelevated(P<0.05). There was no significant difference on ERK/MAPK(P>0.05). Conclusions ①The combination of Shugan-Yishen formula with tamoxifen can inhibit the LCC9 cells. The inhibition effect reaches the peak at 48th hour. ②The mechanism of Shugan-Yishen formula plus TAM combination effects on human breast cancer TAM-resistant cell line LCC9 may improve the sensitivity of ERαby inhibiting the expression of HER2, ERK/MAPK.
