MicroRNAs (miRNAs) are a class of small,non-coding,single-stand RNA molecules which are composed of 21-25 ribonucleotides.They regulate gene expression at post-transcription and participate in many important biological processes including cell growth,apoptosis,viral infection and cancer development.At present,the studies on miRNAs in cervical lesion include miRNAs expression characteristic of cervical cancer and precancerous lesion,the association with HPV infection and prognosis of cervical lesion,cervical cancer development,diagnosis and therapy.

AIM: To investigate the clinical effect of one-dose multiple point scanning panretinal photocoagulation (PRP) in the treatment of non-proliferative diabetic retinopathy (NPDR).METHODS:Selected 78 patients 132 eyes with NPDR in our hospital from January 2015 to June 2016,the patients were randomly divided into observation group (42 patients of 72 eyes) and control group (36 patients of 60 eyes).The observation group was given one-dose multi-point scanning PRP.The control group was given a single point scanning,3 to 4 times to complete the PRP.To observethe therapeutic effect in two groups,the average visual field threshold,the flash electroretinogram (F-ERG) a,b wave amplitude,the laser energy and so on were observed.RESULTS:The effective rate of the observation group and the control group were 84.7% and 83.3%,the difference was not statistically significant (P>0.05).In the observation group and the control group,at 6mo after treatment,the leakage area of retinal neovascularization was lower than that before treatment (P<0.05).The visual field threshold and F-ERG a wave amplitude differences were not statistically significant (P>0.05).F-ERG b wave amplitude were 221.94±70.18mV and 219.82±69.56mV in the observation group and the control group at 6mo after treatment which were significantly lower than that before treatment (P<0.05).The laser energy of the observation group was 541.23 ± 56.39mW,significantly higher than the control group 326.39±78.83mW (P<0.05),while the energy density was 0.34±0.14mW·ms/mm2,significantly less than the control group 2.01±0.97mW·ms/mm2(P<0.05).The incidence of complications in the observation group and the control group were 8.3% and 15.0%,the difference was statistically significant (P<0.05).CONCLUSION:The clinical effect of multiple point scanning PRP in the treatment of NPDR is better than single point multiple PRP with advantages of lower energy density and less laser damage.

The JAK/STAT pathway contributes to control gene expression,cell growth,proliferation,differentiation,apoptosis and immunoregulation.Recent studies have found that the JAK/STAT pathway was closely related to the occurrence and development of lymphoid neoplasms.The study of JAK/STAT pathway could lead to new treatment strategies for lymphoid neoplasm treatment.

Objective Abdominal pain, shoulder pain, and incision pain after laparoscopic cholecystectomy ( LC) are com-mon complaints of the patients.This study was to observe the effects of pulmonary recruitment ( PR) in reducing post-LC abdominal pain, shoulder pain, and incision pain. Methods A total of 138 patients treated by LC were randomly assigned to a PR ( n=67) and a control group (n=71).The former underwent postoperatively five 5-second-long manual inflations of the lungs by positive pres-sure ventilation with 40 cmH2 O to discharge CO2 from the abdominal cavity, while the latter received traditional passive deflation of CO2 .At 6, 12, 24, and 48 h after surgery, we recorded the incidences of abdominal pain, shoulder pain, and incision pain and as-sessed the pain intensity using the visual analogue scale ( VAS) . Results Compared with the control group at 12 and 24 h after sur-gery, the PR group showed significant decreases in the incidence rate of upper abdominal pain (90.14%vs 74.63%and 91.55%vs 73.13%, both P<0.05), with VAS scores of 4.32 ±2.73 vs 2.72 ±1.67 and 4.04 ±2.55 vs 2.67 ±1.49 (both P<0.05), as well as in that of shoulder pain (56.34% vs 47.76% and 74.65% vs 56.72%, both P<0.05), with VAS scores of 3.68 ±3.10 vs2.61 ±1.97 and 4.15 ±3.23 vs 2.78 ±1.88, both P <0.05). However, no significant differences were observed in the incidence or severity of incision pain between two groups at any time points after surgery (P>0.05). Conclusion Pulmonary recruitment can re-duce the incidence rates and severity of upper abdominal pain and shoulder pain, but has no effect in alleviating incision pain following laparoscopic cholecystectomy.

Objective To investigate the protective effect of astragaloside on cardiomyocyte mitochoddria and inhibition effect on cardiomyocytes apoptosis of the rats with heart failure, and explore the treatment mechanism. Methods Sixty SD rats were randomly divided into control group, model group, astragaloside group, and trimetazidine group. The last three groups were injected subcutaneously with isoproterenol to make the heart failure model. Astragaloside group was given astragaloside 50 mg/(kg?d), and trimetazidine group was given trimetazidine 10 mg/(kg?d) orally for three consecutive weeks. At the end of the experiment, the myocardial tissue specimens of each group were made, inverted fluorescence microscope was utilized for measuring mitochondrial membrane potential (MMP), immunoblotting was utilized for detecting cardiomyocyte telomerase reverse transcriptase (TERT) expression, and flow cytometry was untilized for detecting cardiomyocyte apoptosis. Results The MMP ratio of astragaloside group was 3.226±0.371, significantly higher than the model group and trimetazidine group (P<0.01). The cardiomyocyte apoptosis rate of astragaloside group was 8.91±2.12, significantly lower than the model group and trimetazidine group (P<0.01), and the most obvious expression of TERT was found in astragaloside group. Conclusion Astragaloside can protect damaged mitochondria, promote TERT expression, inhibit cardiomyocyte apoptosis and protect cardiomyocytes.
