Objective:To investigate the correlation between hematopoietic cell kinase (HCK) and the expression level of the mitochondrial ribosomal protein L13 (MRPL13) and hematopoietic multimode ultrasound.Methods:204 female breast cancer patients treated by surgery in Quzhou people’s Hospital from Jan. 2017 to Sep. 2020 were selected as study subjects. Breast cancer tissues and adjacent normal tissues were extracted intraoperatively. Preoperative conventional ultrasound, shear wave elastography (SWE) and contrast-enhanced Ultrasonography (CEUS) were used to detect HCK and MRPL13 expression levels. Univariate analysis and binary Logistic regression were used to analyze the correlation between multi-mode ultrasonic features and HCK and MRPL13.Results:The positive expression ratios of HCK and MRPL 13 in breast cancer tissues were significantly higher than those in adjacent tissues ( χ2 was 5.625, 7.197; P was 0.018, 0.007) . In conventional ultrasound features, the proportions of HCK-positive breast cancer patients with irregular mass edges, microcalcifications, and grade II to III blood flow classification were significantly higher than those of HCK-negative patients ( χ2 was 7.437, 16.684, 23.262; P was 0.006, <0.001, <0.001) ; The proportion of MRPL13-positive breast cancer patients with a maximum diameter of ≥2 cm, irregular edges of the tumor, and grade II-III blood flow classification was significantly higher than that of MRPL13-negative patients ( χ2 was 4.676, 11.118, 8.389; P was 0.031, 0.001, 0.004) . For SWE signs, the proportion of HCK positive breast cancer patients with hard ring sign was significantly higher than that of HCK negative patients ( χ2=11.220, P=0.001) ; the proportion of MRPL13 positive breast cancer patients with hard ring sign and black hole sign was significantly higher than that of MRPL13. Those who were negative ( χ2 was 4.482, 8.775; P was 0.034, 0.003) . Among CEUS characteristics, the proportion of HCK-positive patients with high enhancement was significantly higher than that of HCK-negative patients ( χ2=7.356, P=0.007) ; the proportion of MRPL13-positive patients with high enhancement and late regression was significantly higher than that of MRPL13-negative patients ( χ2 was 9.165, 7.631; P was 0.002, 0.006) . The results of binary logistic analysis showed that there was microcalcification ( OR=4.619, 95% CI=2.657-8.119, P=0.009) , blood flow classification II to III ( OR=4.150, 95% CI=2.547-7.954, P=0.015) and high enhancement of CEUS ( OR=4.150, 95% CI=2.547-7.954, P=0.015) are independent risk factors for positive expression of HCK; blood flow grade II to grade III ( OR=4.213, 95% CI=3.145-8.557, P=0.012) , appearance of black hole sign ( OR=5.246, 95% CI=2.864-10.378, P<0.001) and high enhancement of CEUS ( OR=3.872, 95% CI=1.887~6.438, P=0.026) were the independent risk factors for the positive expression of MRPL13. Conclusion:The multimodal ultrasonographic features of breast cancer are helpful to predict the expression levels of HCK and MRPL13, so as to provide new imaging ideas for early diagnosis of breast cancer, the designation of treatment options and the preoperative non-invasive assessment of breast cancer prognosis.

Objective To evaluate the influence of tissue factor pathway inhibitor 2(TFPI-2)gene on the proliferation and invasion of K562.Methods The expression vector pcDNA3.0/TFPI-2 was transfected into human leukemia line K562 cells(K562-T)by using liposome,then the mRNA and protein TFPI-2 were detected by real-time RT-PCR and western blot separately.The growth curve and the colony-forming unit assay were used to measure the ability of cells growth and transwell chamber model was employed to test the ability of cell invasion in vitro.Results Expression of mRNA and protein of TFPI-2 was detected in transfected cells.The growth rate and self-replication ability of K562-T cells were lower than those of the two control groups obviously.The number of K562-T cells to traverse a Matrigel-coated membrane was dramatically decreased compared with that of non-expressing cells.Conclusion The gene of TFPI-2 can inhibit the growth,proliferation and invasion of the K562 cells.

Professor JIA Chunsheng believes that "Dongyuan's acupuncture therapy" proposed by GAO Wu could not entirely reflect LI Dongyuan's academic thought of acupuncture and moxibustion. Hence, we collected all of the academic works of LI Dongyuan and extracted the texts relevant with acupuncture-moxibustion therapy, titled as Dongyuan's acupuncture-moxibustion therapy. This process contributed to the deeper study on Dongyuan's acupuncture and moxibustion academic thought. By the influence of Dongyuan's acupuncture-moxibustion academic thought, in association with his clinical experience for dozens of years, Professor JIA Chunsheng proposed that acupuncture and moxibustion should pay attention to the regulation and tonification of spleen and kidney. In clinical practice, Zhongwan (CV 12), bilateral Tianshu (ST 25), Qihai (CV 6) and Guanyuan (CV 4) are commonly selected to consolidate the root, cultivate the primary and treat the spleen and kidney simultaneously. The locations of the above selected points are distributed like a star. This "star-like point selection method" points to the importance of the spleen and kidney (the primary qi). For many diseases, especially the disorders of internal injury, the star-like acupuncture therapy is commonly used and the relevant acupoints are supplemented. The good clinical efficacy has been achieved.

Objective To investigate the prognostic value of platelet to lymphocyte ratio (PLR) for early virological response in Entecavir (ETV)-treated chronic hepatitis B (CHB) patients with genotype C infection.Methods Ninety-one genotype C CHB patients with HBV DNA≥1×105 copies/mL were treated with ETV (0.5 mg/d) for 10-13 days.The correlation between PLR and viral load decline was evaluated by Pearson or Spearman's rank correlation coefficient.Stepwise linear regression analysis was used to establish the prediction model of virological response.Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of PLR for early virological response in ETV-treated patients with genotype C hepatitis B virus (HBV) infection.Results After 10-13 days of ETV treatment, HBV DNA decreased ≥1×lg copies/mL from baseline in 89 cases of the 91 patients, while HBV DNA declined ≥2×lg copies/mL in 65 patients and 4 patients achieved HBV DNA<500 copies/mL.HBV DNA decline was positively correlated with baseline PLR levels (r=0.235 09, P<0.05).After adjustment for age, gender, Hepatitis B e Antigen (HBeAg), and treatment days, HBV DNA decline was still positively correlated with baseline PLR levels (r=0.220 26, P<0.05).Area under curve (AUC) of prediction model including age , baseline aspartate transaminase (AST) and HBV DNA was 0.759 (95% CI : 0.660-0.859, P<0.01).After adding PLR to the prediction model, the AUC was 0.780 (95% CI: 0.685-0.875, P<0.01).Conclusions PLR is predictive to early virological response in ETV-treated CHB patients with genotype C infection.Higher baseline PLR level indicates a better virological response.PLR monitoring should be recommended in CHB patients with antiviral treatment in clinical practice.

Objective To observe the effect of very early intervention with cerebellar fastigial nucleus electrical stimulation and neurodevelopmental treatment on infants of central coordination disturbance(CCD).Methods 86 infants(0～6 months)with central coordination disturbance were divided into intervention group and control group.The intervention group was treated with neurodevelopmental treatment,cerebellar fastigial nucleus(FN)electrical stimulation and family interference.The control group was treated with neurodevelopmental treatment and family interference.The effect of infant was assessment with Gross Motor Function Measure(GMFM)and Gesell Development Test after 3 months treatment.Results The total improved incidence of the intervention group was 95.6%,which was significantly higher than that of the control group(P<0.01).The difference of scores in social,adaptive and motor area improved in the intervention group compared with that of control group(P<0.05).Conclusion Very early intervention with cerebellar fastigial nucleus electrical stimulation can facilitate the development of gross motor,social,adaptive capability of infants with CCD treated with neurodevelopmental therapy.

Objective : To analyze the trends in incidence of thyroid cancer in Huangpu District, Shanghai from 2002 to 2017, so as to provide insights into the management of thyroid cancer. Methods : The incidence of thyroid cancer in Shanghai from 2002 to 2017 was collected from the cancer registration system created by Shanghai Center for Disease Control and Prevention. The crude and standardized incidence of thyroid cancer were estimated by year, gender and age groups, and annual change percentage ( APC ) was calculated to analyze the trends in incidence of thyroid cancer. Results : A total of 2 854 new cases of thyroid cancer were reported in Huangpu District from 2002 to 2017, and the crude and standardized incidence rates of thyroid cancer were 19.57/105 and 13.47/105, with APC of 18.15% and 17.93% ( P<0.05 ), respectively. The crude and standardized incidence rates of thyroid cancer were 10.02/105 and 7.06/105 in men, with APC of 19.58% and 19.04% ( P<0.05 ), and were 28.90/105 and 19.95/105 in women, with APC of 17.33% and 16.99% ( P<0.05 ), respectively. The crude incidence of thyroid cancer was higher in women than in men ( P<0.05 ). In addition, there were two peaks in the crude incidence of thyroid cancer in patients at age of 35 to 39 and 60 to 64 years, with crude incidence rates of 28.98/105 and 33.36/105, respectively. Conclusions The incidence of thyroid cancer appeared a tendency towards a rise in Huangpu District from 2002 to 2017, and much attention should be paid to females and patients aged 60 to 64 years.

OBJECTIVE: To assess the clinical efficacy and health economic value of non-invasive prenatal testing (NIPT) for the prenatal screening of common fetal chromosomal aneuploidies. METHODS: 10 612 pregnant women from October 2017 to December 2019 presented at the antenatal screening clinic of the General Hospital of Tianjin Medical University were selected as the study subjects. Results of NIPT and invasive prenatal diagnosis and follow-up outcome for the 10 612 pregnant women were retrospectively analyzed and compared. Meanwhile, NIPT data for two periods were analyzed for assessing the health economic value of NIPT as the second- or first-tier screening strategy for the prenatal diagnosis of fetal trisomies 21, 18 and 13. RESULTS: The NIPT was successful in 10 528 (99.72%) subjects, with the sensitivity for fetal trisomies 21, 18 and 13 being 100%, 92.86% and 100%, and the positive predictive value (PPV) being 89.74%, 61.90% and 44.44%, respectively. The PPV of NIPT for sex chromosome aneuploidies was 34.21%. Except for one false negative case of trisomy 18, the negative predictive value for trisomy 21, trisomy 13 and other chromosomal abnormalities were 100%. For pregnant women with high risk by serological screening, advanced maternal age or abnormal ultrasound soft markers, NIPT has yielded a significantly increased high risk ratio. There was no statistical difference in the PPV of NIPT among pregnant women from each subgroup. NIPT would have higher health economic value as a second-tier screening until 2019, while compared to 2015 ~ 2017, its incremental cost-effectiveness ratio as a first-tier screening had declined clearly. CONCLUSION The screening efficacy of NIPT for trisomies 21, 18 and 13 for a mixed population is significantly better than conventional serological screening, but it is relatively low for sex chromosomal abnormalities. NIPT can also be recommended for populations with relatively high risks along with detailed pre- and post-test genetic counselling. From the perspective of health economics, except for open neural tube defects, it is possible for NIPT to replace the conventional serological screening in the future as its cost continues to decrease.
