Objective To explore the effect of Zhengu Pills ( a kidney-tonifying and blood-activating Chinese medicine) and Guci Fengshi Pills ( a dampness-dispelling and blood-activating Chinese medicine) on bone remodeling of cell model in vitro. Methods MC3T3-E1 and RAW264.7 cells were differentiated into osteoblasts ( OB) and osteoclasts ( OC) after stimulated by different inductive agents respectively, and then OB and OC were co-cultured. Immunocytochemical staining was applied to identify the construction of co-cultured OB and OC system. The serum containing corresponding medicine was prepared after the rats were given intragastric administration of Diacerein, Zhengu Pills and Guci Fengshi Pills. And then the obtained serum was used for treatment of co-cultured cells separately. At the end of experiment, Western blotting and real-time polymerase chain reaction (PCR) tests were carried out. Results The osteoprotegerin (OPG) expression was increased and gene expression of glycoprotein 130 (gp130) was decreased in co-cultured cells after treatment with the serum containing Zhengu Pills and Guci Fengshi Pills ( P<0.05) . Conclusion Zhengu Pills and Guci Fengshi Pills have therapeutic effects on osteoarthritis ( OA) by inhibiting the bone resorption function of OC by the down-regulation of gp130 and by enhancing bone formation and increasing the bone density through recombinant murine’s RANK ligand (RANKL) -RANK-OPG system.

Objective A meta-analysis was conducted to evaluate the correlation between hepatitis C virus (HCV) infection and the incidence of intrahepatic cholangiocarcinoma (ICC).Methods EMBASE,MEDLINE,Web of Science,CNKI,Weipu and Wanfang databases were retrieved to identify eligible studies which were published between January 2000 and May 2015.Pooled odds ratios (OR) with 95％ confidence interval (95％ CI) were calculated using RevMAN 5.3.Results 14 case-control studies and 2 cohort studies were included in this study.As there was great heterogeneity among these 16 studies (Chi2 =53.18,df =15,I2 =72％,P ＜0.05),the random-effect model was employed.The combined risk estimates of all the studies showed a significant increase in ICC incidence with HCV infection (OR =3.96,95％ CI 2.63-5.95,P ＜ 0.05).The Begg funnel plot showed no evidence of publication bias.Conclusion HCV infection is related to an increased risk of ICC incidence.

Objective To explore the dosimetric advantages of computed tomography-based and ultrasound-guided three-dimensional image-quided brachytherapy (3D-IGBT) combined with intracavitary/interstitial (IC/IS) brachytherapy for locally advanced cervical cancer.Methods A total of 45 patients with FIGO (2009) stage ⅠB2-ⅣA locally advanced cervical cancer who received radical external beam radiotherapy and 3D-IGBT combined with IC/IS brachytherapy in our hospital from 2013 to 2014 were analyzed.After the treatment with 192Ir-based IC/IS brachytherapy,patients had needles removed from the original images and received treatment only from IC radiation sources.Dosimetric differences in the planning D90 for high-risk clinical target volume (HR-CTV),D90 for intermediate-risk CTV (IR-CTV),and D2 cm3 for the bladder,rectum,sigmoid colon,and small intestines were determined and analyzed by paired t-test.Results A total of 260 after-loading treatment plans,including IC/IS treatment plans for 130 patients and IC treatment plans for 130 patients,were made.The D90 for HR-CTV and D90 for IR-CTV in the IC/IS brachytherapy group were significantly higher than those in the IC brachytherapy group (P =0.000;P =0.000).Moreover,the average D2cm3 values for the bladder and rectum were significantly reduced in the IC/IS brachytherapy group compared with those in the IC brachytherapy group (P =0.000;P =0.006).Conclusions The 3D-IGBT combined with IC/IS brachytherapy not only achieves a higher dose for the target volume,but also reduces the radiation dose to the bladder and rectum in the treatment of locally advanced cervical cancer.

Objective To investigate the clinical application of Utrecht applicator in three-dimensional image-guided brachytherapy (3D-IGBT) for locally advanced cervical cancer,as well as its application discipline in intracavitary/interstitial (IC/IS) therapy.Methods A retrospective analysis was performed for the clinical data of 45 patients with locally advanced cervical cancer who received radical radiotherapy,and the patients received external beam radiotherapy followed by 3D-IGBT.A total of 130 times (n =45) of IC/IS therapy were performed,and the patients who received such therapy were all enrolled.The patients who met the target dose fractionation defined in the plan were enrolled as group A (n=37,86 times),and the other patients were enrolled as group B (n=22,44 times).Two groups difference was analyzed with Group t-test.Results The frequencies of use of 15-,20-,and 25-mm ovoids by the applicator were 50.0％,20.0％,and 30.0％,respectively,and the 30-mm ovoid was not used.A total of 499 needles were used,and the frequencies of use of 6,7,10,and 11 insertion holes were 23.1％,21.2％,21.2％,and 24.1 ％,respectively.Group A had a significantly lower mean number of the needles than group B (3.7 vs.4.2,P=0.008).Compared with group B,group A had a significantly lower mean high-risk clinical target volume (CTV)(40.71±18.43 cm3 vs.51.81±14.74 cm3,P=0.001),as well significantly lower width and height of high-risk CTV (P=0.011 and 0.006),but the thickness of high-risk CTV was similar between the two groups (P=0.595).The difference between height and insertion depth (DH) was similar between the two groups (P=0.366).Group A had a smaller difference between width and pinhole distance Dw than group B (P=0.007).Conclusions When IC/IS therapy is performed for locally advanced cervical cancer,the 15-,20-,and 25-mm ovoids of Utrecht applicator and 6,7,10,and 11 insertion holes are frequently used.When the number of needles is no less than 4 and the depth is no less than 3 cm,width is the major factor which affects the planned dose.

In China, COVID-19 epidemic is currently showing a sporadic state, and the task of epidemic prevention is still arduous. Brachytherapy (BT) plays a critical role in the treatment of cancer. For some cancer receiving radiotherapy, use of BT can not be replaced or excessively delayed. Nevertheless, the recommendations or guidelines regarding the application of BT during COVID-19 epidemic have been rarely reported. In this article, a few recommendations on the application of BT during COVID-19 epidemic were retrieved and the work experience of Department of Radiation Oncology, China-Japan Union Hospital of Jilin University in the early epidemic period was summarized, aiming to provide relevant reference for the use of high-dose-rate BT for malignant tumor patients during COVID-19 epidemic.

Purpose: This study was performed to analyze the rule of confluence of the caudate lobe bile duct (CLD) into the left hepatic duct (LHD) and to discuss the protective strategy during left hemihepatectomy. Methods: MRI of 400 patients and T-tube angiography images of 100 patients were collected, and the imaging rules of the confluence of the CLD into the LHD were summarized. The clinical data of 33 patients who underwent left hemihepatectomy using the protective strategy were analyzed. Results: MRI and T-tube angiography images showed that the length from the confluence point of the CLD into the LHD to the confluence of the left and right hepatic ducts was 1.19 ± 0.40 cm and 1.26 ± 0.39 cm, respectively. The average angle between the longitudinal axis of the 2 bile ducts was 68.27° ± 22.59° and 66.58 ± 22.88°, respectively. Coronal and cross-sectional images showed that inflow from the foot side to the cranial side was noted in 79.8% and 82.0% of patients, respectively, and inflow from the dorsal to the ventral side was observed in 84.5% and 88.0%, respectively. Based on these imaging rules, the safe transection length and plane were summarized, and the CLD was effectively protected in 33 cases of left hemihepatectomy. Conclusion In left hemihepatectomy, the LHD should be transected at least 1.5 cm away from the confluence of the left and right hepatic ducts, and the plane of transection should be oblique to the dorsal side at an angle of 45° with the LHD, these parameters represent an effective strategy to protect the CLD.

Objective To investigate the application of superficial brachytherapy in the treatment of the upper arm skin invasion of breast cancer. Methods This study was conducted on a female patient with ipsilateral chest wall, axillary, and clavicle recurrence, and circumferential skin and subcutaneous soft tissue invasion in the ipsilateral upper arm after modified radical mastectomy for breast cancer. The upper arm lesions were treated with 192Ir high-dose-rate superficial brachytherapy at a dose of 50 Gy in 25 fractions. Dosimetric parameters were compared between superficial brachytherapy and electron irradiation plan. Treatment outcomes and adverse reactions were observed during and after treatment. Results The heterogeneity index(HI)for target volume was 1.62 and 1.94 in superficial brachytherapy and electron irradiation plan, respectively. The D90,D100, and V150%for clinical target volume were higher in superficial brachytherapy than in electron irradiation plan(205 vs. 189 cGy;163 vs. 110 cGy;6.3% vs. 3.23%). The D0.1,D1, and D2for the humerus were also higher in superficial brachytherapy than in electron irradiation plan(155 vs. 80 cGy;147 vs. 55 cGy;145 vs. 36 cGy)and much lower than the bone tolerance dose in both treatments. The lesions partially subsided after superficial brachytherapy. The main adverse reaction was grade 2 radiation dermatitis. Conclusions Compared with electron irradiation plan, superficial brachytherapy is a simple and effective approach for irradiation of shallow target volume with a large curvature, such as circumferential upper arm skin invasion of breast cancer. Superficial brachytherapy achieves satisfactory homogeneity and dose distribution.

Objective:To evaluate the feasibility of indocyanine green fluorescence imaging technology applied in thyroid surgery to identify parathyroid gland.Methods:From Oct 2021 to May 2022, data of 42 patients undergoing thyroidectomy via gasless unilateral axillary approach in Zhejiang Provincial Hospital of Traditional Chinese Medicine were retrospectively analyzed. Cases using intraoperative fluorescence imaging technology(42 cases) were compared with conventional laparocopic approach.Results:The number of parathyroid glands dissected in the study group 1.57±0.61 was higher than that in the control group 0.56± 0.59 ( t=-5.472, P<0.05). The PTH value of the study group was (2.88±1.23)pmol/L on the first day after operation, which was higher than that of the control group (2.16±0.10)pmol/L ( t=-1.844, P<0.05). The blood parathyroid hormone value on the third day(3.22±1.31)pmol/L was higher than that of the control group (2.55±0.81) pmol/L ( t=-2.041, P<0.05). There were 2 cases of hypoparathyroidism in the study group, less than 5 cases in the control group, but there was no significant difference between the two groups( χ2=0.942, P>0.05). There was 1 case of hypocalcemia in the study group and 3 cases in the control group ( χ2=0.731, P>0.05). Conclusion:Using indocyanine green fluorescence imaging technology to identify parathyroid gland is feasible, simple, fast, safe and effective.
