AIM:To investigate the safety and complications of femtosecond laser corneal small incision lenticule extraction(SMILE) procedure and discuss the prevention and treatment.METHODS: We retrospectively studied the complications of 403 patients(799 eyes) with myopia and myopic astigmatism treated by SMILE.RESULTS: All the patients underwent the operation successfully.Only 1 case(1 eye)suffered from dark spot and changed to femtosecond laser-assisted LASIK(FS-LASIK), 5 cases(5 eyes, 0.6%) suffered from the suction loss, 11 cases (17 eyes, 2.1%) developed opaque bubble layer.All patients gained perfect uncorrected visual acuity(UCVA) (20/20).The best corrected visual acuity(BCVA) did not decrease after operations.The incidence of haze and diffuse lamellar keratitis was low (0.3% and 0.4%, respectively)and no other complications were observed.There was 9 eyes in 6 patients (1.1%) found regression of refraction at 6mo after surgery, while the UCVA of rest patients reached 1.0 at 3mo after surgery.CONCLUSION: The SMILE procedure has high safety for myopia and myopic astigmatism.Effective prevention and management of the complications is the key to achieve the satisfactory visual acuity.

Single cell RNA sequencing (scRNA-seq) is an advanced technology to study the transcriptome information at the single cell level. The application of this technology can attribute to analyze the heterogeneous map of cells in the process of disease development, and precisely identify the specific cell subsets that are responsive to pharmacological therapy. Currently, scRNA-seq technology has been widely applied in the field of drug research, including studies on therapeutic targets, drug-induced adverse reactions, drug resistance and vaccine. This work reviews the application of scRNA-seq technology in drug discovery, which offers a scientific basis for personalized and accurate medication therapy.

Objective: To explore the therapeutic efficacy and mechanism of transcutaneous electrical acupoint stimulation (TEAS) for menopausal insomnia. Methods: A total of 80 patients with menopausal insomnia were randomly divided into a control group and an observation group, with 40 cases in each group. The patients in the control group received conventional Western medication treatment, and the patients in the observation group received TEAS on the basis of conventional Western medication treatment. The treatment for both groups lasted for 4 weeks. Before and after treatment, Pittsburgh sleep quality index (PSQI) and modified Kupperman scale were evaluated, and the serum levels of estradiol (E2) and follicular stimulating hormone (FSH) were measured. The therapeutic efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05); in the control group, the improvement of PSQI score was significant (P<0.05), while the change of modified Kupperman score was insignificant (P>0.05); the PSQI and Kupperman scores in the observation group were significantly improved after treatment (both P<0.05), and there were significant differences between the observation group and the control group in PSQI and Kupperman scores (both P<0.05). After treatment, the serum E2 and FSH levels in the control group were not statistically different from those before treatment (both P>0.05); the serum E2 level was significantly increased (P<0.05), and the FSH level was decreased (P<0.05) in the observation group after treatment, and the between- group differences in serum levels of E2 and FSH were significant (both P<0.05).Conclusion: TEAS plus conventional Western medication in treating menopausal insomnia is effective, and can significantly improve the symptoms of insomnia and menopause, which may be related to the regulation of serum E2 and FSH levels.

Primovist is a newly developed hepatocytespecific agent that is transported into the hepatocyte through organic anion transporting polypeptides (OATPs) and excre ted into bile through canalicular multiorganic anion trans porters.Primovist uptake is usually reduced in HCC cells that present hypointensity on the hepatobiliary phase,there fore this agent may help differentiate HCC from other neoplasms and improve histological grading.This article will further explore the use of Primovist in liver cirrhosis and small hepatocellular carcinoma.

Obiective To solve the problem of charge evasion in medical equipment and improve the management of medical equipment and increase income of the hospital.Methods The control system was designed and used based onembedded system as real-time monitor in the medical equipment. Results This system can realize the real-time monitor of the medical equipment and improve the management of hospital. Conclusion The system resolves the problem of charge evasion effectually and increases the income of the hospital.

OBJECTIVE:To establish a method for determination of Morphine in Pipazhike soft capsules by using SPE-HPLC.METHODS:SPE condition:C18 cartridge.15mL MeOH-water(3∶ 1)and 5mL water were used as elution solvent.RESULTS:Morphine had a good linearity in the rang of 0.233 5～ 1.868 0? g(r=0.999 9).The average recovery rate was 97.6%(RSD=1.2%,n=5).CONCLUSION:This method is simple,accurate,and reproducible,and can be used to effectively control the content of Morphine in Pipazhike soft capsules.

Objective To investigate the role of 15 kinds of growth regulatory factors in the pathogenesis of benign prostatic hyperplasia (BPH). Methods 15 kinds of growth regulatory factors involving cell proliferation and apoptosis were studied by immunohistochemistry with computer assisted quantitative image analysis.The mean percent area densities of stroma,epithelium and glandular lumen in BPH were examined by quantitative image analysis. Results Positive relations were found bewteen expressions of basic fibroblast growth factor (bFGF),transforming growth factor ?, fibronectin, type Ⅳ collagen and proportions of stroma (r=0.323?0.278?0.235?0.241,P

Objective To explore influence of Naoxintong capsule combined with edaravone on clinical efficacy and vascular endothelial function of patients with type-2 diabetes complicated with cerebral infarction.Methods 80 cases of patients with type-2 diabetes complicated with cerebral infarction treated in Shengsi People's Hospital in Zhejiang from January 2014 to January 2016 were selected as the objects, and were divided into control group and study group randomly, forty-one cases in each group.The control group were given edaravone treatment, and the study group were added Naoxintong capsule on the basis of the control group, treatment for two weeks in the two groups.Clinical therapeutic effect of the two groups and changes of TCM syndrome score before and after treatment were compared, and scores of nerve function defect and daily life ability were evaluated, and changes of blood glucose and glycosylated hemoglobin levels were detected, and endothelin ( ET-1 ) , nitric oxide ( NO ) , thromboxane B2 ( TXB2 ) and 6-keto prostaglandin F1(6-keto-PGF1) were tested before and after treatment in the two groups.Adverse reactions were observed in the two groups in treatment. Results The total effective rate of the study group was significantly higher than that of the control group(P<0.05), and TCM syndrome scores of the two groups were significantly decreased after treatment in the two groups(P<0.05), which of the study group was significantly lower than that of the control group(P<0.05).After treatment, NIHSS score of the two groups significantly decreased(P<0.05), and ADL score significantly increased(P<0.05), and changes of the study group were significantly higher than those of the control group(P <0.05).Fasting blood glucose and glycosylated hemoglobin levels significantly decreased in the two groups(P<0.05), which of the study group were significantly lower than those of the control group ( P <0.05 ).Levels of ET-1 and TXB2 significantly decreased ( P <0.05 ) , levels of NO and 6-keto-PGF1 significantly increased ( P <0.05 ) , and changes in the study group were significantly higher than those in the control group(P<0.05).There was no significant difference in incidence of adverse reactions between the two groups.Conclusion The effect is obvious of Naoxintong capsule combined with edaravone in treratment of patients with type-2 diabetes complicated with cerebral infarction, and can improve vascular endothelial function of patients.It can be widely used in clinical.
