Objective To investigate the value of the three-dimensional endorectal ultrasonography (3D-ERUS) in the tumor staging before transanal endoscopic microsurgery (TEM).Methods The clinical data of 30 patients with rectal cancer who underwent 3D-ERUS before TEM at the Nanjing Hospital of Traditional Chinese Medicine from April 2012 to December 2013 were retrospectively analyzed.The accuracy,sensitivity and specificity of the 3D-ERUS were evaluated according to the results of the postoperative pathological examination.The consistency of the results of the 3D-ERUS and postoperative pathological examination were compared by Kappa consistency test.Results Of 30 patients,25 patients in stage T0,3 in stage T1 and 2 in stage T2 were diagnosed by preoperative 3D-ERUS.There were 2 patients (stage pT0) with inflammatory polyp by postoperative pathological diagnosis,6 patients (stage pT0) with tubular adenoma,16 patients (stage pT0) with villioustublar adenoma,2 patients (stage pTis) with carcinoma in situ,2 patients (stage pT1) with tectal adenoma and 2 patients (stage pT2) with rectal adenoma.There were 2 patients with excessive tumor staging by 3D-ERUS,1 patient in stage pT0 was misdiagnosed in stage T1,1 in stage pT1 was misdiagnosed in stage T2 and 1 in stage pT2 was misdiagnosed in stage T1 with insufficient tumor staging.The accuracy of 3D-ERUS in the preoperative tumors staging of TEM was 90.0％ compared with the resuls of postoperative pathological examination.The accuracy,sensitivity and specificity of 3D-ERUS in stage pT0,pTl,and pT2 of TEM were 96.7％,90.0％,93.3％ and 96.2％,50.0％,50.0％ and 100.0％,92.8％,96.4％,respectively.There was a significant difference in the consistency between preoperative 3D-ERUS and postoperative pathological examination (κ =0.685,P ＜ 0.05).Conclusion 3D-ERUS is an accurate clinical method in the preoperative tumors staging of TEM,and can be used as the preoperative assessment for TEM.

In order to increase the production of insecticidal crystal proteins Cry1 and Cry2, firstly, Plack-ett-Burman design was applied to evaluate the effectiveness of the related nutrition factors; it was found that the soybean powder and MnSO4?H2O were significant factors for Cry1 production, but the yield of Cry2 wasn’t effected remarkably in such medium. Then the steepest ascent experiment was adopted to approach the optimal region of the medium composition. Lastly, the optimal concentration of the soybean powder and MnSO4?H2O was 11.5 and 0.02 g/L, obtained by response surface methodology (RSM). The final yields of Cry1 and Cry2 was 0.32 mg/mL and 0.11 mg/mL, increasing twice more than that in the medium optimized before. The median lethal concentration (LC50) of optimal medium was 1.09 ?L/mL. The toxicity to Heli-coverpa armigera was significantly enhanced than the old one.

AIM: To investigate the efficacy of anti-inflammatory treatment and anti-vascular endothelial growth factor(VEGF)treatment on different types of macular edema secondary to retinal vein occlusion(RVO-ME).

METHODS: The clinical data of RVO-ME patients who were treated in the Department of Ophthalmology, the First Affiliated Hospital of Zhengzhou University from 2019-06/2020-12 were retrospectively collected. A total of 108 cases(108 eyes)of RVO-ME patients were collected, including 52 cases(52 eyes)with cystoid macular edema(CME), 38 cases(38 eyes)with macular edema with serous retinal detachment(SRD), and 18 cases(18 eyes)with diffuse retinal thickening(DRT). Patients with various types of ME were further classified into anti-VEGF group and anti-inflammatory group. The observation metrics such as best corrected visual acuity(BCVA)and foveal thickness(CMT)before and 3mo after surgery were collected and compared in each group.

RESULTS: There was no difference in baseline data between the anti-VEGF group and the anti-inflammatory group in all types of ME patients(all P>0.05). Patients with CME in the anti-VEGF group in BCVA, CMT, and the sum of CME diameter after operation were different from that before operation(Z= -4.463, -4.541, -4.541, all P<0.001); the postoperative BCVA, CMT, and the sum of CME diameter in the anti-inflammatory group were significantly different from those before operation(Z= -3.743, -4.345, -4.372, all P<0.001); and there was no difference between the anti-VEGF group and the anti-inflammatory group in the postoperative CMT and the sum of CME diameter(Z= -1.017, -0.968, all P>0.05), but there was a difference in BCVA after operation in two groups(Z= -1.978, P<0.05). SRD patients in the anti-VEGF group had differences in postoperative BCVA, CMT, and SRD heights compared with preoperative ones(Z= -4.111, -4.198, -4.198, all P<0.01); the BCVA, CMT, and SRD height in the anti-inflammatory group after operation were different from those before operation(Z= -3.410, -3.408, -3.408, all P<0.05); and there was no difference in BCVA and CMT between the two groups after operation(Z= -0.857, -1.030, all P>0.05), but the postoperative SRD height in the anti-inflammatory group was significantly lower than that in the anti-VEGF group(Z= -2.117, P<0.05). DRT patients in the anti-VEGF group were significantly different in BCVA and CMT after operation compared with preoperative ones(Z= -2.207, -2.521, all P<0.05), and in the anti-inflammatory group after injection, BCVA and CMT were significantly different from preoperative ones(Z= -2.207, -2.521, all P<0.05). There were differences in BCVA and CMT after injection in the anti-inflammatory group compared with those before operation(Z= -2.207, -2.803, all P<0.05). There was no difference in postoperative BCVA and CMT between the two groups(Z= -0.359, -0.845, all P>0.05).

CONCLUSION: Anti-inflammatory and anti-VEGF treatments are effective for all kinds of ME in improving vision and reducing CMT. Anti-VEGF treatment is superior to anti-inflammatory treatment in improving BCVA of CME patients and is inferior to anti-inflammatory in decreasing SRD thickness of SRD patients.

OBJECTIVETo explore the alone and joint diagnostic value of serum golgi protein 73 (GP73), alpha-fetoprotein (AFP) and the percentage of lectin-reactive aipha-fetoprotein (AFP-L3) of primary hepatic carcinoma (PHC), and provide a novel method for diagnosis for PHC and screening for high-risk population.

METHODSELISA was used to detect the serum level of GP73, AFP and AFP-L3% in 81 cases of PHC,176 cases chronic hepatitis and liver cirrhosis, 30 cases other tumber cancer and 40 cases of health people.

RESULTSThe sensitivity of GP73, AFP and AFP-L3% in PHC is 77.78%, 62.69% and 51.85%, and the specificity is 84.55%, 86.99% and 96.34%, respectively. Joint detection could increase the sensitivity up to 88.89%.

CONCLUSIONGP73 was a high sensitivity mark for dignosis of PHC, while AFP-L3% was a high specificity mark for dignosis of PHC. The joint detection could improve PHC diagnostic performance.

OBJECTIVETo investigate the effect of oridonin on the human acute lymphocytic leukemia cell line Jurkat and its mechanism.

METHODSJurkat cells were cultured in vitro and treated with various concentrations (0, 1.25, 2.5, 5, and 10 μmol/L) of oridonin for different lengths of time (24, 48, and 72 hours). The proliferation of Jurkat cells was analyzed by MTT assay. The changes in nuclear morphology were evaluated by fluorescence microscopy at 12 hours after treatment with various concentrations of oridonin. The expression levels of Brg1, P53, and C-myc were determined by semi-quantitative Western blot in Jurkat cells treated with various concentrations of oridonin for 24 hours or 5 μmol/L oridonin for various lengths of time (0, 2, 6, 12, and 24 hours). The expression levels of P53 and C-myc and proliferation of Jurkat cells were evaluated after Brg1 expression was knocked down by Brg1-specific siRNA.

RESULTSCompared with the control group, the proliferation of oridonin-treated Jurkat cells was significantly inhibited in a concentration- and time-dependent manner (P<0.05). According to the florescence microscopic analysis, oridonin treatment led to nuclear pyknosis in Jurkat cells. Compared with the control group, Jurkat cells treated with 5 μmol/L oridonin had reduced expression of Brg1 and C-myc but elevated expression of P53. Brg1 knock-down led to a significant reduction in proliferation of Jurkat cells (P<0.05), up-regulated expression of P53, and down-regulated expression of C-myc.

CONCLUSIONSOridonin can inhibit the proliferation of Jurkat cells, probably via the Brg1 signaling pathway.

On the basis of the chromogenic reaction between Hg and CuI, a semi-quantitative solid sampling Hg analyzer comprising the catalytic furance, Hg testing tube, air pump and smart cellphone was developed. White carrier 101 was chosen as the adsorbent for CuI to react with Hg from the catalytic furnace. The established Hg analyzer can not only visually recognize the coloration when Hg exceeding the limit standard, but also semi-quantitatively detect the Hg content in cosmetics fast using a smart cellphone and RGB analysis software, after direct solid sampling introduction of cosmetics sample. The instrumental detection limit ( LOD) of mercury was 50 ng, the linearity ranged from 50 ng to 2500 ng, the linear regression coefficient ( R2) was higher than 0. 97, and the RSD of the corresponding RGB values was 6% ( n=11 ) . Nine real cosmetics samples were measured by the established method, whose relative differences of Hg contents with that by the standard method (Safety Technical Specification for Cosmetics, 2015 edition) were less than 10% . The whole analytical time can be controlled within 5 min. The established instrumental method is simple, fast, accurate and visual, and extremely suitable to fast and on-site monitoring of Hg in cosmetics samples.

Objective To investigate the relationship between the incidence of deep vein thrombosis (DVT) during hospitalization and the energy of injury in tibial plateau fractures (TPFs).Methods 140 patients were enrolled in the study between September,2014,and October,2017 in Honghui Hospital,Xi'an Jiaotong University.According to the Schatzker classification,the low-energy group (Schatzker Ⅰ-Ⅲ) X-ray showed a simple or lateral fracture or compression fracture of the lateral plateau (n =63);the high-energy group (Schatzker Ⅳ-Ⅵ) X-ray showed the medial tibia or double of the tibial plateau (n =77).Duplex Ultrasonography was performed in lower extremities before and after surgical intervention for DVT evaluation and record the incidence of DVT,the days during hospitalization,the blood loss during surgery and the level of D-Dimer.All patients received mechanical and chemical thromboprophylaxis.The patient was followed up for one month after surgery,and the lower extremity ultrasound was reviewed and recorded.The measurement data were expressed as ((x) ± s),and the categorical variables were expressed in composition ratio.The measurement data were all in accordance with the normal distribution and the variance was uniform.The t-test was used,and the Chi-square test was used for comparison between groups.Results The incidence of thrombosis of tibial plateau fracture in TPFs was 36.43％ and 46.43％ pre-operation and post-operation respectively.The thrombosis incidence was 31.75 ％ (20/63) in the low-energy group and 40.26％ (31/77) in the high-energy group pre-operation.The thrombosis incidence was 44.44％ (28/63) in the low-energy group and 48.05％ (37/77) in the high-energy group post-operation.Statistical analysis showed no significant difference between the two groups pre-operation (P =0.298) and post-operation(P =0.785).The days during hospitalization [(11.94 ± 4.18) d,(9.56 ± 2.54) d],the blood loss during surgery [(208.96 ±224.43) ml,(129.68 ± 142.14) ml] and the level of D-Dimer [(2.39 ± 3.38) mg/L,(1.21 ± 2.32) mg/L] at pre-operation showed differences in the high energy group and the low energy group,respectively.Conclusions The incidence of DVT in TPFs is high during the hospital,but most of DVT is concentrated in the distal to the knee.Although the incidence of high energy injury and low energy injury DVT is not significantly different in TPFs,we should also be alert to the occurrence of DVT.

2 in some patients with the loss of high and medium sized vWF multimers in plasma.Eight patients with vWD were identified, wherein two were characterized as type 1,4 as type 2A and 2 as type 3 respectively.Conclusion The panel of tests is suitable for diagnosis and classification of vWD.

Cholecystokinin (CCK) is a brain-gut peptide with broad biological activities. It is one of the main regulating hormones in the digestive system, and it plays an important physiological role in the central and peripheral nervous system as a neurotransmitter or a neuromodulator. Recently, many reports have demonstrated that there were a number of SNPs on CCK gene, of which -45C/T and -196G/A showed certain correlation with a variety of psychiatric states such as schizophrenia, depressive disorder, suicidal behavior, Parkinson's disease, etc. These SNPs may be used in paternity testing and personal identification. In addition, it may also become one of the auxiliary indicators in some special cases of forensic pathology.

Prostate biopsy is the gold standard for the diagnosis of prostate cancer. In order to successfully and effectively complete the biopsy, clinicians should not only select the correct puncture method, but also pay attention to the pain control of patients undergoing puncture. It is necessary to select a reasonable anesthetic method for biopsy. The pain during biopsy comes from the skin, muscle and other structures in the puncture approach, and also comes from the prostate capsule. Therefore, the anesthesia emphasis of transperineal and transrectal biopsy approaches will also be different. The use of appropriate anesthesia is of great significance to improve the patient's cooperation and ensure the success rate of biopsy. With the continuous maturity of the technology and concept of prostate biopsy, a single anesthesia method has been unable to meet the actual anesthetic needs of biopsy, and the use of multi-site and multi-phase combined anesthesia for different sources of pain has become the mainstream anesthetic option.
