Objective:To detect the value of utilizing bpMRI in prostate biopsy in the detection of prostate cancer with PSA≤20ng/ml.Methods:The clinical data of 394 patients who underwent prostate biopsy in the First Affiliated Hospital of Nanjing Medical University from November 2017 to October 2019 were retrospectively analyzed. Of all the patients, 177 underwent modified systematic biopsy, named TRUS group, 217 patients accepted pre-biopsy bpMRI examination, undergoing modified systematic biopsy if Prostate Imaging Reporting and Data System (PI-RADS) score < 3 or MRI-TRUS cognitive fusion targeted prostate + systematic biopsy if PI-RADS score ≥ 3, named MRI group. The median age of TRUS group was 66 (61, 74) years old, prostate specific antigen (PSA) was 9.52 (7.26, 12.30) ng / ml, and prostate volume (PV) was 36.84 (28.95, 57.72)ml. The median age of MRI group was 66 (59, 72) years old, PSA was 8.84 (6.65, 12.16) ng/ml, and PV was 39.45 (29.25, 58.69)ml. There was no difference in above parameters between the two groups. The χ 2 test was used to compare the detection rate of prostate cancer and clinically significant prostate cancer (CsPCa) between the two groups. Results:There was no significant difference in the detection rates of prostate cancer between TRUS group and MRI group [51.41% (91/177) vs. 48.39% (105/ 217), P = 0.550], but the detection rates of CsPCa were significantly different [26.55% (47/177) vs. 36.41% (79/217), P = 0.037]. In patients with PSA ≤ 10 ng / ml, there was no significant difference in the detection rates of prostate cancer between the two groups [43.62% (41/94) vs. 43.08% (56/130), P = 0.936], but there was a significant difference in the detection rates of CsPCa [17.02% (16/94) vs. 28.46% (37/130), P = 0.047]. There was no significant difference in the detection rates of prostate cancer [60.24% (50/83) and 56.17% (48/87), P= 0.504] and the detection rates of CsPCa [37.35% (31/83) vs. 48.28% (42/87), P = 0.150] between the two groups. The total detection rates of the last two needles in TRUS group and MRI group were 23.16% (41/177) and 36.63% (86/217), respectively, with significant difference ( P=0.001); the detection rates of CsPCa in the last two needles were 11.86% (26/177) and 29.03% (63/ 217), respectively, with significant difference ( P < 0.001). In MRI group, the detection rates of prostate cancer in patients with PI-RADS score <3, 3, 4, 5 were 21.21% (7/33), 25.84% (23/89), 73.24% (52/71), 95.83% (23/24), respectively; the detection rates of CsPCa were 12.12% (4/33), 17.98% (16/89), 54.93% (39/71), 83.33% (23/24), respectively. Conclusions:In patients with PSA ≤ 20 ng / ml, prostate biopsy based on bpMRI may improve the detection of CsPCa, especially in patients with PSA ≤ 10 ng/ml.

BmK AngM1 is a long-chain scorpion toxin purified from the venom of Buthus martensii Karsch. It has been reported to exhibit evident analgesic effect and low toxicity, and has the potential to be a novel analgesic drug. The BmKAngM1 gene was transformed into Pichiapastoris GS115. Mut+ and Mut(s) recombinant strains were screened by phenotype and Mut+ recombinant strains were used to detect BmK AngMl gene copy number in the real-time PCR. Expression of BmK AngM1 in the Mut+ recombinant strain was compared with that of the Mut(s) recombinant strain with the same single copy of BmK AngM1 gene under the same condition. The results indicated that the transcription level of BmK AngM1 gene in the Mut(s) recombinant strain was 2.7 fold of that in the Mut recombinant strain in the real-time PCR, and the expression of BmK AngM 1 in the Mut(s) recombinant strain was 1.5 fold of that in the Mut+ recombinant strain. Therefore, Mut(s) recombinant strain showed better ability to express BmK AngM1 than Mut+ recombinant strain.

Objective To investigate the current status of tobacco control in public places in Jiading District, after the introduction of "Tobacco Control Regulation in Public Places of Shanghai" (amendment), providing basic data for further implementing regulations. Methods The method of field observation was adopted to conduct the monitoring in 14 representative public places, including site staff in 109 places in April and September. Results The display rate of tobacco control propaganda increased(χ²=10.588, P < 0.001), but the posting rate of pictures for smoking control warnings decreased(χ²=6.272, P=0.012);the differences between two monitoring results were both statistically significant; the smoking rate in the staff within the workplaces decreased to 5.17%(χ²=20.973, P < 0.05);the differences between two monitoring results were both statistically significant. Conclusion The situation of tobacco control in Jiading District public places is good, but in some places smoking control should be further strengthened, and the intensity of tobacco control in public places should be maintained.

The response rules of pressing pain on the back section in the Governor Vessel in patients with gastro-esophageal reflux disease (GERD) were studied to provide references for the diagnosis and treatment of GERD. Seventy-six cases of GERD were included into an observation group while 30 healthy volunteers were recruited into a control group. A mechanical measurement device of pressing pain that could measure the pain threshold was adapted to observe the pressing pain on the back section in the Governor Vessel in GERD patients and healthy volunteers. The test area is from spinous process of the 1st thoracic vertebra to that of the 12th thoracic vertebra (T1 -T12), including acupoints and non-acupoints on the Governor Vessel. As a result, in the observation group the pain threshold of T5-T7 spinous process clearance, which was the location of Shendao (GV 11), Lingtai (GV 10) and Zhiyang (GV 9), was lower than that in the control group (all P < 0.05). This result indicated that there was significant pressing pain in T5-T7 spinous process clearance in patients with GERD, which could be taken as an important auxiliary diagnosis and a new thinking method in the treatment of GERD with acupuncture.
