Objective:To explore the progress and prospect of evaluation methods for infertility patients.Methods:From September 2017 to December 2020,199 cases of infertility patients who have accepted mini-hysteroscopy examination in the Department of Gynecological Endocrinology,Beijing Obstetrics and Gynecology Hospital,Capital Medical University.The patients who had primary ovary insufficiency,tubal infertility were excluded;patients with hysteroscopy contradiction,such as acute or sub-acute vaginal tract inflammation,en-dometrium lesion or endometrium carcinoma,severe cardiovascular,liver or kidney insufficiency were excluded.40 patients were excluded and 15 patients lost follow up,144 patients were eventually included in the analysis.The patient's age,body mass index,infertility etiology,preoperative and postoperative stimulate ovulation cycle,pregnancy state and pregnancy time were recorded.The effect of mini-hysteroscopy on ovulation induction cycle was analyzed in pregnant patients.Results:The average age of 144 patients was 32.10±4.67 years old.96 (66.67％) patients were found to have intrauterine abnormalities,while 48 (33.33％) patients were found to have normal intrauterine cavity.48 cases of pregnancy,accounting for 33.33％;the median and interquartile ranges[M (Q1,Q3)]of ovulation induction cycles before and after surgery were respectively[3 (0,5)],[2 (1,3)],the difference was statistically significant(P ＜ 0.05).Among the 48 pregnant patients,32 of them had no structural lesions in hysteroscopy,the ovula-tion induction cycle of these patients before and after hysteroscopy were respectively[5 (0,9)],[1 (0,3)],the difference was statistically significant (P ＜ 0.05).Conclusion:Uterine cavity evaluation is important for the assessments of fertility.As an advanced diagnosis instrument,mini-hysteroscopy can not only timely detect the intrauterine abnormalities of patients,but also with great application value in shorten the ovulation cycle in infertility patients and increase the pregnancy rate.

Objective:To investigate the application value of transcranial Doppler (TCD) in the prognosis assessment of nerve function in patients with acute cerebral infarction (ACI) after intracranial mechanical thrombectomy.Methods:A retrospective analysis was conducted. The clinical data of 43 patients with acute anterior circulation cerebral infarction who received intra-arterial mechanical thrombotomy for recanalization admitted to Taizhou Central Hospital from January 2018 to December 2019 were analyzed. The modified Rankin scale (mRS) score of patients were followed up by telephone at 3 months after surgery to evaluate the prognosis of neurologic outcome. Patients with mRS score 0-2 were enrolled in the good prognosis group, while those with a score of 3-6 were enrolled in the poor prognosis group. The gender, age, past history, underlying diseases, occluded arteries, atherosclerotic stenosis and bridging treatment, time from onset to reperfusion, blood flow dynamics under TCD at 1 day after thrombectomy, and National Institutes of Health stroke scale (NIHSS) scores before and 1, 7, and 14 days after thrombectomy were compared between the two groups. Multivariate Logistic regression analysis was used to screen the prognostic factors of nerve function at 3 months after mechanical thrombectomy in patients with ACI. The receiver operating characteristic (ROC) curve was drawn to evaluate the prognostic value for neurological function assessed by TCD.Results:Forty-three patients were enrolled in the final analysis, with 23 patients in the good prognosis group and 20 in the poor prognosis group. The recanalization was successfully achieved in both groups without complications. However, the hemodynamics of intracranial arteries evaluated by TCD 1 day after operation in both groups still showed partial or complete occlusion, and the hemodynamics of patients in the poor prognosis group was worse than that in the good prognosis group (poor blood flow: 40.0% vs. 0%, inadequate blood flow: 30.0% vs. 17.4%, good blood flow: 30.0% vs. 82.6%), and the differences were statistically significant (all P < 0.01). Before thrombotomy, there was no significant difference in NIHSS score between the two groups. After thrombotomy, the NIHSS score of the two groups gradually decreased with the extension of time, but the NIHSS score at 14 days after operation of the poor prognosis group was still significantly higher than that of the good prognosis group (10.55±2.93 vs. 4.65±1.70, P < 0.01). Univariate analysis showed that compared with the good prognosis group, the proportion of patients with diabetes and arteriosclerosis stenosis in the poor prognosis group were significantly increased (30.0% vs. 4.3%, 45.0% vs. 17.4%, both P < 0.05), and the time from onset to reperfusion was prolonged (minutes: 385.9±96.2 vs. 294.5±95.1, P < 0.01). Multivariable Logistic regression analysis showed that the therosclerosis stenosis [odds ratio ( OR) = 9.334, 95% confidence interval (95% CI) was 1.092-79.775, P = 0.041] and the reperfusion time ( OR = 1.016, 95% CI was 1.006-1.027, P = 0.002) were associated with prognosis of nerve function at 3 months after mechanical thrombectomy in patients with ACI. ROC curve analysis suggested that the evaluation of intracranial hemodynamics by TCD might be able to predict the prognosis of neurological function in patients with ACI after 3 months of intracranial mechanical thrombectomy, the area under ROC curve (AUC) was 0.768 (95% CI was 0.620-0.917), the sensitivity was 65.0%, the specificity was 87.0%, the positive predictive value was 82.6%, and the negative predictive value was 70.0%. Conclusion:The evaluation of intracranial hemodynamics assessed by TCD is helpful in early judging the prognosis of neurological function in patients with ACI after intracranial mechanical thrombectomy.

Objective To meta-analyze the effect of mirror therapy on the lower limb motor function and ac-tivities of daily living of stroke survivors so as to evaluate its clinical efficacy. Methods Medline, PubMed, OT seeker, the Cochrane library, the Wanfang database, the VIP database and the CNKI were searched for reports of randomized and controlled trials (RCTs) of the effect of mirror therapy on the lower limb motor function and activities of daily living of stroke survivors published between December 2008 and December 2018. Strict inclusion and exclu-sion criteria were applied, and the quality of the documents was comprehensively assessed according to version 5.1.0 of the Cochrane manual. The results were analyzed using version 5.2 of the RevMan software suite. Results Four-teen trials were included. Meta-analysis showed that mirror therapy had been shown to improve the patients'scores of Fugl-Meyer assessment ( FMA ), functional ambulance category ( FAC ) and modified Barthel index ( MBI ). Conclusion Mirror therapy can improve the motor function of the affected lower extremities of stroke survivors and their ability in the activities of daily living.

Objective To study the effect and mechanism of dexmedetomidine combined with sufentanil on postoperative analgesia in elderly patients with abdominal surgery. Methods Ninety-six elderly patients having undergone abdominal surgery in the First Affiliated Hospital of Wenzhou Medical University from January 2016 to June 2017 were enrolled, and they were divided into a control group and an observation group by random number table method, 48 cases in each group. General anesthesia was performed in the operation, and after surgery venous analgesic pump was used for analgesia in both groups. Analgesic method: the control group was given sufentanil 2 μg/kg and tropisetron 5 mg; the observation group was given dexmedetomidine 2 μg/kg, sufentanil 2 μg/kg and tropisetron 5 mg. The changes of pain and sedation score, conventional indexes [systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiratory rate (RR), pulse blood oxygen saturation (SpO2)], oxidative damage indexes [lipid peroxide (LPO), glutathione peroxidase (GSH-Px), Cu-Zn superoxide dismutase (Cu-Zn SOD)], stress response indexes [cortisol (Cor), epinephrine, norepinephrine (NE)], platelet activation indexes granule membrane protein-140 (GMP-140), thromboxane A2(TXA2) and the incidence of adverse reactions were observed in both groups. Results ① After surgery the visual simulation score (VAS) and Ramsay score in both groups were higher than those before surgery, and showed a tendency firstly increased and then decreased, and reached to peak value 2 hours after operation [VAS score:the control group was 3.24±0.98 vs. 1.95±0.93, observation group was 3.19±1.03 vs. 1.98±0.95; Ramsay score:the control group was 3.26±0.51 vs. 1.90±0.45, observation group was 3.77±0.53 vs. 1.92±0.42], began to decline 6 hours after operation, reached to valley value 48 hours after operation, and there was no significant difference in VAS scores between the two groups (2.02±0.64 vs. 1.98±0.95), Ramsay score was significantly higher in observation group than that in control group (2.59±0.41 vs. 2.10±0.21). ② Since 2 hours after the operation, the SBP, DBP, HR and RR in the observation group began to be lower than those in control group, 12 hours after surgery their values reached their valleys [SBP (mmHg, 1 mm Hg = 0.133 kPa): 113.2±13.5 vs. 122.1±10.3, DBP (mmHg): 67.5±9.9 vs. 76.4±8.6, HR (bpm): 64.5±6.9 vs. 71.4±7.5, RR (bpm): 14.8±1.1 vs. 15.8±0.8, all P < 0.05]; while SpO2did not change a great deal. ③ LPO, Cor, epinephrine, NE, GMP-140, TXA2of two groups after operation were higher than those before operation, GSH-Px and Cu-Zn SOD were lower than those before operation. However, LPO, Cor, epinephrine, NE, GMP-140, TXA2in observation group were significantly lower than those in control group [LPO (μmol/L): 6.4±0.8 vs. 9.8±1.1, Cor (ng/L): 148.2±19.1 vs. 239.3±27.8, epinephrine (μg/L): 124.2±13.9 vs. 207.1±23.5, NE (μg/L): 109.2±14.8 vs. 183.3±21.6, GMP-140 (μg/L): 27.13±3.82 vs. 39.06±4.83, TXA2(ng/L): 422.30±53.74 vs. 610.43±73.21, all P < 0.05], GSH-Px and Cu-Zn SOD in observation group were significantly higher than those in the control group [GSH-Px (U/L): 426.7±58.7 vs. 307.9±51.2, Cu-ZnSOD (μg/L): 311.3±42.5 vs. 231.6±34.1, all P < 0.05].④ The incidence of adverse reaction nausea in the observation group was significantly lower than that in the control group [4.17% (2/48) vs. 37.5% (18/48)]. Conclusion Dexmedetomidine combined with sufentanil used in elderly patients after abdominal surgery has significant analgesic effect, can effectively inhibit platelet activation, and decrease the contents of GMP-140 and TXA2.

Spasticity is one of common manifestations of upper motor neuron injury, and often evaluated with semi-quantitative scales. Ultrasound elastography (UE) can provide elastic information for muscle tissue, and can be used for the evaluation of muscle tension after cerebral palsy and stroke, as well as the efficacy of treatment. It correlates well with clinical spasm rating scales. However, UE may also be used for assessment of spasticity after spinal cord injury and multiple sclerosis, etc.
