Non-invasive blood glucose monitoring will be the development direction for detecting the blood glucose concentration of body in time. In this way, the concentration of the blood glucose can be controlled effectively, then the complicating diseases of diabetes can be reduced, so it is of great significance for diagnosis and treatment of diabetes. The recent developments of non-invasive blood glucose concentration monitoring technologies, including basic principles, results of verification test and instruments, are discussed, especially three methods with instruments facing market. The existing problems of these methods are also discussed. Finally, some difficult points of current non-invasive blood glucose monitoring methods are further discussed and the future trend of the technologies has been pointed out according to the above analysis.

Objective:To investigate the effects of remimazolam besylate and midazolam on postoperative cognitive function of patients undergoing gynecologic laparoscopic surgery under general anesthesia.Methods:From May 2019 to January 2021, 120 patients with gynecological laparoscopic surgery under general anesthesia in Haikou Maternal and Child Health Hospital were selected and divided into control group (60 cases) and observation group (60 cases) by random number table. The control group was given 0.05 mg/kg midazolam and 0.50 μg/kg sufentanil and 0.15 mg/kg vecuronium bromide were used for anesthesia induction. Patients in the observation group were given 0.3 mg/kg remimazolam besylate and 0.50 μg /kg sufentanil and 0.15 mg/kg vecuronium were used for anesthesia induction. The levels of hemodynamic indexes before anesthesia (T 0), during anesthesia (T 1), and after intubation (T 2) as well as the levels of postoperative anesthesia recovery indexes were compared between the two groups. The Visual Analogue Scale (VAS) score and Mini-Mental State Examination (MMSE) scores were recorded and compared before surgery, 24 h, 72 h after surgery. The total incidence of adverse reactions after surgery was recorded and compared between the two groups. Results:The heart rate (HR) at T 1 and T 2 in the two groups was higher than that at T 0, the oxygen saturation (SpO 2) at T 1 and T 2 was lower than that at T 0, the mean arterial pressure (MAP) at T 1 was lower than that at T 0, and the MAP at T 2 was higher than that at T 0, with statistically significant difference (all P<0.05); The HR and MAP at T 1 and T 2 in the observation group were lower than those in the control group, and SpO 2 was higher than those in the control group (all P<0.05); The recovery time of spontaneous respiration, eye opening time and extubation time in the observation group were significantly shorter than those in the control group (all P<0.05); The MMSE score at 24 h and 72 h after operation was lower than that before operation, and the VAS score at 24 h was higher than that before operation in both groups (all P<0.05); The MMSE scores in the observation group at 24 h and 72 h after operation were significantly higher than those in the control group (all P<0.05), and there was no significant difference in the VAS scores at 24 h and 72 h after operation between the two groups ( P>0.05); There was no significant difference in the total incidence of adverse reactions between the two groups (all P>0.05). Conclusions:Remimazolam besylate has little effect on cognitive function of patients undergoing gynecologic laparoscopic surgery under general anesthesia, with fast recovery and high safety, which is worthy of clinical promotion.

Objective To evaluate the effect of local treatment for the prognosis of hormonesensitive metastatic prostate cancer.Methods A systematic review of the literature about local treatment for the prognosis of hormone-sensitive metastatic prostate cancer was performed,searching Medline,Embase,Cochrane Library,CBM,CNKI,VIP and Wan Fang database from January 2001 to October 2016.Two authors reviewed the records to identify comparative studies.A meta-analysis was conducted using Review Manager 5.0.Results Five studies were enrolled,including 29 354 patients.Meta-analysis showed that,compared with no local treatment,local treatment had a significant beneficial effect in 5-year overall survival rate (OR =0.18,95 % CI 0.15-0.22,P < 0.01),5-year disease specific survival rate (OR =0.39,95 % CI 0.31-0.49,P<0.01) as well as 3-year overall survival rate (OR =0.47,95% CI 0.35-0.62,P<0.01).Sub-group analysis showed that,compared with no local treatment,prostatectomy had a significant beneficial effect in 5-year overall survival rate (OR =0.17,95 % CI 0.12-0.25,P < 0.01),5-year disease specific survival rate (OR =0.30,95% CI 0.22-0.40,P <0.01) as well as 3-year overall survival rate (OR=0.25,95%CI 0.19-0.32,P <0.01),and external beam radiation therapy only had a significant beneficial effect in 3-year overall survival rate (OR =0.54,95% CI 0.42-0.69,P < 0.01).Conclusions Prostatectomy and external beam radiation therapy may have a survival benefit for hormone-sensitive metastatic prostate cancer.Prospective randomized controlled studies are necessary because of the limits of current studies.

Objective To explore the application of nephron-sparing surgery in giant renal angiomyolipomas with the maximum diameter greater than 15 cm and its relevant surgical experience.Methods Between July 2014 to January 2017,5 patients with giant renal angiomyolipoma greater than 15 cm was admitted to our hospital for nephron-sparing surgery.The patients were all female ranging in age from 32-50 years (43.0 ± 7.1) years.According to the tumor imaging characteristics,we divided them into 3 different types including diffuse endogenous,exogenous and mixed type.All the tumors meet the criterion of exogenous type,ranging in diameter from 15.0-28.0 cm (20.4 ± 5.8) cm.4 patients harbored one single tumor and the other bilateral tumors.All the giant tumors located on the right side.Open transperitoneal nephron-sparing surgery was performed.Result During the operation,to find the joint site between the tumor and normal kidney is the key procedure in order to reserve more normal renal parenchyma.The operation time ranged from 105-175 min (125.4 ± 28.4) min,warm ischemia time 8-20 min (15.8 ±4.8) min,blood loss 50-400 ml (162.0 ± 141.5) ml.The average postoperative drainage volume ranged from 50-165 ml (99 ± 45) ml,the time of drainage tube removal 1-8 days (4.0 ± 2.6) days.The postoperative serum creatinine had no significant change compared to the value before operation (P =0.808).Postoperative hospital stay was 5-12 days (7.2 ± 2.9) days.Benign renal angiomyolipoma with negative margins was diagnosed as expected.No patient had a recurrence after a 1-32 months follow-up.Conclusion Nephron-sparing surgery could be used selectively in patients with giant renal angiomyolipoma greater than 15cm.For the tumors with the characteristic of exogenous type on imaging assessment before operation,open transperitoneal nephron-sparing surgery was an optional choice and could be implemented safely.

Objective:
To investigate the relationship between SUVmax on preoperative 68Ga-PSMA PET-CT and the clinicopathological characteristics of patients treated with radical prostatectomy.
Methods:
The clinicopahtological data of patients evaluated with 68Ga-PSMA PET-CT preoperatively and treated with radical prostatectomy between May 2016 and August 2019 were retrospectively reviewed. 31 patients with a mean age (63.1±4.9) and baseline PSA (72.71±173.15)ng/ml were enrolled. Their BMI mean (24.6±3.0)kg/m2. Baseline testosterone of 14 patients was (4.72±1.64)ng/ml.Based on the Gleason scores related ISUP classification, all patients were classified into grade one in 5 cases, grade 2in 7 cases, grade 3 in 4 cases, grade 4 in 10 cases and grade 5 in 5 cases. The clinical classification included 6 cases in T2a stage, 2 cases in T2b stage, 17 cases in T2c stage, 1 case in T3a stage, 4 cases in T3b stage and 1 case in T4 stage. SUVmax was accessed by two independent professional nuclear medicine physicians. SUVmax was 12.49±9.38. SPSS 16.0 software was used to do statistic analysis.
Results:
The post-operative pathological results showed the surgical margin positive in 19 cases, negative in 12 cases, vascular positive in 5 cases, negative in 20 case, positive nerve invasion in 20 cases and negative in 11 cases. 2 patients were low risk, 7 patients were medium risk and 22 patients were high risk according to D′Amico classification. Based on the basis of PSA(≤10 or>10) and Gleason score(≤6 or>6), 6 patients were in group with low PSA and low Gleason score, 5 patients were low PSA and high Gleason score, 9 patients were high PSA and low Gleason score, 11 patients were high PSA and high Gleason score. SUVmax had a significant positive relationship with pathological ISUP(
