OBJECTIVE To explore the feasibility of microfluidic chip in the rapid detection of pesticide residues in Dendrobium officinale. METHODS The sample was extracted with organic solvent, and purified with QuEChERS dispersive SPE, high throughput screening of enzymes for pesticide residue detection from different manufacturers by centrifugal microfluidic chips. The matrix interference was investigated by negative samples with different horizontal adding methods. The sensitivity, repeatability sand accuracy of the microfluidic chip were investigated, and sample results determined by mass spectrometry were compared with them. RESULTS The results revealed that the significant difference rate of rapid detection method was 0.25; the sensitivity was 99.6%; the specificity was 96.4%; the false negative rate was 0.39%; the false positive rate was 3.57%; the accuracy was 98.81%. Two methods of rapid detection of pesticide residues by microfluidic chip and mass spectrometry were used to detect 40 batches of samples. The results indicated that the two methods had a high consistency, compliance rate of testing results were 100%. CONCLUSION Microfluidic chip rapid detection technology can be used for detecting pesticide residues in Dendrobium officinale, which can meet the screening needs of the basic non-professional person to detect the quality of large quantities of pesticide residues.

Objective:To discuss the efficacy and safety of ultrasound-guided rectus sheath block (RSB) combined with subcostal transversus abdominis plane block(TAPB) in peritoneal dialysis catheter implantation in patients with end-stage renal disease.Methods:A total of sixty patients (scheduled for elective peritoneal dialysis catheter placement from June 2018 to March 2019 in Wuhan First Hospital were randomly divided into two groups: local anesthesia group(group LA, 30 patients) and ultrasound-guided RSB combined with subcostal TAPB (group NB, 30 patients). Group LA: local infiltration anesthesia was performed with 1% lidocaine and 0.5% ropivacaine 20ml; group NB: RSB, 1% lidocaine and 0.5% ropivacaine 15 ml were injected into the lateral rectus sheath, and TAPB, 1% lidocaine and 0.5% ropivacaine 20 ml were injected into the transversus abdominis plane. Mean arterial blood pressure (MAP) and heart rate (HR) were recorded at the point of entering the operating room (T 0), after anaesthesia (T 1), at the beginning of operation (T 2), twenty minutes after the beginning of operation (T 3), and at the end of the operation (T 4). The duration of operation, the times of additional local anesthetia during the surgery, the score of visual analogue scale (VAS) during and 24 h after the surgery, the rate of alteration to general anesthesia and the occurrence of adverse reactions were recorded. Results:In group LA, compared with T 0, MAP and HR at T 2 and T 3 increased significantly: (93.1 ± 9.7), (99.8 ± 11.6) times/min vs. (78.4 ± 10.5) times/min and (105.1 ± 13.7), (110.5 ± 14.4) mmHg (1 mmHg = 0.133 kPa) vs. (92.1 ± 12.8) mmHg, P<0.05. In group NB, there were no differences among T 0-T 4. At T 2 and T 3, MAP and HR in group LA were higher than those in group NB ( P<0.05). Compared with that in group LA, the duration of operation time decreased significantly in group NB ( P<0.05). The times of additional local anesthetia during the surgery in group LA were more than those in group NB ( P<0.05). Compared with those in group LA, the VAS scores during and 24 h after the surgery in group NB were significantly lower: (3.25 ± 0.65) scores vs. (5.85 ± 0.76) scores, (1.46 ± 0.57) scores vs. (2.37 ± 0.45) scores, P<0.05. There were no significant differences in the rate of alteration to general anesthesia between the two groups: 3.33% (1/30) vs. 0, P>0.05. There was no adverse reaction in these two groups. Conclusions:Ultrasound-guided rectus sheath block combined with subcostal transversus abdominis plane block is safe and effective in peritoneal dialysis catheter implantation. The effect of intraoperative anesthesia is definite, with little influence on hemodynamics. The postoperative analgesia effect is good, without obvious anaesthesia-related adverse events.

Objective: To compare the safety and efficacy of pulsed dye laser (PDL) with different sessios for the East Asian infants with port-wine stains(PWS). Methods: From September 2016 to September 2017, 24 East Asian infants with untreated PWS, who met the standards of enrollment, received seven treatments by PDL at 2-week intervals and three treatments at 6-week intervals at adjacent locations in each patient 2 months after final treatment. The efficacy outcome was compared with Wilcoxon signed-rank test, while the safety was compared using Fisher′s exact test. Results: Of the 24 patients, 20 completed study. Seven patients had multiple sites, given a total of 62 treated PWS sites. Among the patients, 18 had lesions on the face and 2 on the extremities. The average blanching rate was (43.71 ± 27.16) % and (43.29 ± 31.58) % for PDL treatments with 7- and 3- sessions, respectively (P>0.05). The result was consistent with independent observer assessment judging that the result of 7 laser treatments was equally with that of 3 treatments (r=0.416, P=0.0008). The average grade was 3.58 ± 1.21 and 3.53 ± 1.16 for 7- and 3-sessions. The patients treated with 7-sessions developed a little more side effects than 3-sessions, including residue purpura, pigmentation changes, eczema and dermatitis. Conclusions After three treatments of PDL, the efficacy may not necessarily increased by more frequent treatments for East Asian infantile PWS.

Objective: To investigate the effects of beta-blocker, propranolol and timolol on the proliferation and apoptosis of hemangioma stem cells (HemSCs). Methods: Different concentrations(3, 30, 90, 150 μmol/L)of propranolol and timolol were added in HemSCs culture respectively for 24, 48 and 72 h, and cell proliferation and apoptosis were detected by flow cytometry. Experimental data were analyzed using SPSS 19.0 software. Statistically significance was determined using Student′s t test. Values of P<0.05 were considered statistically significant. Results: Proliferation assay indicated that different concentrations of propranolol and timolol could inhibit HemSCs proliferation, and inhibition degree increased with increasing concentration. However, the effects of propranolol was slightly stronger than that of timolol at high concentrations (30, 90 and 150 μmol/L), but the opposite was observed at low concentration(3 μmol/L)(P<0.05). The results of apoptosis experiment showed that timolol had stronger effect than propranolol in promoting apoptosis at low concentrations (3 and 30 μmol/L), which was 13.7% and 1.1% higher, respectively. Conclusions Inhibiting HemSCs proliferation and promoting apoptosis may be one of the mechanisms of propranolol and timolol in treating infantile hemangioma.The specific effects of both varies with the concentration and time.

BACKGROUND:MicroRNAs (miRNA) through regulating specific target gene mRNA expression play important roles in different processes of diseases. OBJECTIVE:To study the interaction of miRNA-21 with its target gene TLR4 in Hela cels. METHODS:The candidate target gene of miRNA-21 was determined according to miRNA analysis databases. The constructed recombinant adenovirus vector carrying pri-miRNA-21 gene was used, which could package and amplify viruses to transfect Hela cels. Then, the expression of fluorescent proteins was detected. Forty-eight hours after transfection of miRNA-21 or control, extracted proteins were used for detection of TLR4 protein using western blot assay. RESULTS AND CONCLUSION:Recombinant adenoviruses pAd/pri-miRNA-21 and pAd/neg at 100 MOI could successfuly infect Hela cels. Bioinformatic analysis suggested several possible binding sites between miRNA-21 and TLR4. The experimental results showed that miRNA-21 down-regulated TLR4 at protein levels, indicating that miRNA-21 can interfere with the expression of TLR4 target gene.

Effects of the leaf-clipped treatment on growth and physiological properties of Rehmannia glutinosa were studied. Result showed that with the increase of the cutting leaves degree, growth rates of shoots and roots were decreased, sugar contents declined, chlorophyll contents decreased and root activities also inhibited. Compared with the normal plant (CK), the root inhibit rates in T1, T2, T3 were 17.53%, 33.41%, 59.47%, respectively. Physiological indexes including chlorophyll contents, root activities and sugar contents also were impacted by the leaf-clipped treatment. The results indicate that to balance source-sink relationship is a very essential method for improving production of R. glutinosa.
