ABSTRACT
ObjectiveTo observe the clinical efficacy of herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of infertility induced by idiopathic asthenozoospermia （iAZS） with kidney-Yang deficiency and collateral obstruction syndrome and its effect on sperm DNA damage and superoxide dismutase （SOD） in the seminal plasma. MethodsA total of 112 eligible patients who met the inclusion criteria were randomly divided into an observation group （56 cases） and a control group （56 cases）. The patients in the observation group were treated with herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription，while those in the control group received levocarnitine oral liquid. The primary observation indicators included spouse pregnancy rate，progressive motility （PR），and total sperm motility，and the secondary observation indicators included sperm DNA fragmentation index （DFI），SOD in the seminal plasma， and improvement of TCM syndromes. The treatment cycle was 12 weeks. Before and after treatment，the PR，total sperm motility，sperm DFI，SOD in the seminal plasma， and TCM syndrome scores were recorded. The patients were followed up for 12 weeks and the pregnancy status of spouses within 24 weeks （half a year） was recorded. The clinical efficacy of the two groups was evaluated. ResultThe pregnancy rate of spouses in the observation group was 15.69% （8/51）， higher than 3.85% （2/52） in the control group （χ2=4.118，P<0.05）. The total effective rate of the observation group was 88.24%（45/51）， superior to 69.23% （36/52）in the control group （Z=-3.402，P<0.01）. After treatment， PR， total sperm motility，sperm DFI， SOD in the seminal plasma， and TCM syndromes of the two groups were improved compared with those before treatment （P<0.05）， and the observation group was superior to the control group （P<0.05）. ConclusionHerb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of iAZS-induced infertility patients with kidney-Yang deficiency and collateral obstruction syndrome can increase PR，total sperm motility， and SOD level in the seminal plasma， reduce sperm DFI，improve the TCM symptoms of patients， and improve the pregnancy rate of spouses. The mechanism may be attributed to the fact that this treatment can increase the SOD level in the seminal plasma of patients，enhance the body's antioxidant function，protect sperm from oxidative stress damage，and reduce sperm DFI.
ABSTRACT
Objective:To investigate the value of Breast Ultrasound Report and Data System (BI-RADS) classification in diagnosis of special types of breast cancer.Methods:A total of 112 patients with special type of breast cancer (112 breast lesions) confirmed by pathology were analyzed by using BI-RADS ultrasound category in the Second Affiliated Hospital, Zhejiang University School of Medicine from August 2009 to August 2020. All patients underwent ultrasound before surgery. The breast lesions were evaluated by senior attending and junior resident according to BI-RADS ultrasound category respectively. Taking histopathological result as the gold standard, the sensitivity and accuracy of BI-RADS classification in the diagnosis of special types of breast cancer were calculated.The differences between different special types of breast cancer in terms of ultrasound characteristics and pathological features were analyzed. Kappa consistency test was used to evaluated the consistency of the results of two physicians.Results:In the 112 patients, pathological results showed that there were 20 cases of metaplastic carcinoma, 19 cases of invasive carcinoma with medullary features, 16 cases of differentiated carcinoma of apocrine gland, 12 cases of mucinous carcinoma, 12 cases of invasive micropapillary carcinoma, 10 cases of invasive papillary carcinoma, 6 cases of invasive lobular carcinoma and 17 cases of other special types of carcinoma. Among them, 4 cases (3.5%) were BI-RADS 3, 13 cases (11.6%) were BI-RADS 4a, 42 cases (37.5%) were BI-RADS 4b, 47 cases (42.0%) were BI-RADS 4c and 6 cases (5.4%) were BI-RADS 5. The accuracy and sensitivity of BI-RADS classification in diagnosis of special types of breast cancer was 96.43% and 96.43%, respectively. There was significant difference in BI-RADS grade among different special types of breast cancer ( P<0.05). Most lesions were characterized by hypoechoic with irregular shape and angular or microlobulated margin. The nodule size, boundary, echo and posterior echo in breast cancer with different special types showed significant differences (all P<0.05). There was a good consistency between the two physicians (Kappa=0.789). Conclusions:The ultrasonography features of different special types of breast cancer are different. BI-RADS classification has great value in diagnosis of special types of breast cancer.

ABSTRACT
Objective To determine whether low frequency ultrasound mediated microbubbles destruction (UMMD) could inhibit VX2 orthotopic hepatic tumor growth in rabbit models.Methods Twenty-four New Zealand white rabbits were implanted with VX2 tumor in left hepatic lobe to establish a homograft rabbit model of liver neoplasms in situ,which were randomly divided into four groups(6 rabbits in each group):group A (intravenous saline only),group B (intravenous microbubbles only),group C (intravenous saline+ low frequency focused ultrasound exposure),and group D (intravenous microbubbles+low frequency focused ultrasound exposure).After 3 days consecutive treatment,tumor volume(TV),and peak intensity (PI) were monitored by conventional ultrasound and contrast enhanced ultrasound(CEUS) on 0,1,7,14 and 21 days after treatment.The rabbits were euthanized at the end of the experiment.Tumor tissues were evaluated by HE stain.Results The parameters of TV and PI of each tumor had no significant difference among four groups before treatment(all P>0.05).TV had no significant difference among four groups on 1 day after treatment(all P>0.05);PI in group C and group D were significantly lower than those in group A and group B (all P0.05).The pathological changes of necrosis tissue,hemorrhagic damage of microvessel and thrombosis were observed in the tumors of group D only,whereas these changes occurred rarely in other groups.Conclusions UMMD can inhibit the growth of VX2 hepatic tumors in rabbits,and be used as a promising novel therapeutic strategy to liver neoplasms.
ABSTRACT
Objective To evaluate the clinical value of contrast-enhanced ultrasound (CEUS) in predicting peripancreatic vascular invasion in pancreatic carcinoma through comparison with the findings on surgical exploration. Methods A total of 94 pancreatic cancer patients (confirmed by pathological examination) were included in this study. The CEUS data were analyzed retrospectively. The enhancement characteristics of lesions were documented. And the peripancreatic vascular invasion were analyzed. The main features of peripancreatic vascular invasion on CEUS were as followings: 1) peripancreatic arteries to be embedded, trapped in the tumor or surrounded by tumor, or to have intraluminal infiltration or luminal stenosis. 2)superior mesenteric vein, portal vein to be surrounded by tumor or to be narrow, distorted or occluded. The CEUS findings were compared with postoperative pathological results. Results 94 patients were diagnosed with pancreatic cancer by pathological examination, including 62 cases of pancreatic head carcinoma, 32 cases of pancreatic tail carcinoma. The imaging of contrast-enhanced ultrasound showed 6 cases (6.4%) of high uneven enhancement, 78 cases (83%) of low uneven enhancement, and 10 cases (10.6%) of heterogeneous enhancement in parenchyma phase, respectively. Twenty-five cases (26.6%) of CA invasion were detected by CEUS, while no invasion was observed in 69 cases (73.4%). Compared with pathological findings, the predictive sensitivity, accuracy, specificity, positive predictive value, negative predictive value of CEUS were 63.6%, 79.7%, 84.7%, 56.0%, 88.0%, respectively. Twenty-seven cases (28.7%) of SMA invasion were detected by CEUS, while no invasion were observed in 67 cases (71.3%). Compared with pathological findings, the predictive sensitivity, accuracy, specificity, positive predictive value, negative predictive value of CEUS were 66.6%, 77.6%, 80.2%, 44.0%, 91.0%, respectively. Besides, PV invasion features were found in 27 cases (28.7%), while 67(71.3%) cases were detected without invasion features. Compared with pathological findings, sensitivity, accuracy, specificity, positive predictive value, negative predictive value of CEUS in predicting PV invasion were 86.6%, 94.6%, 98.4%, 96.2%, 94.0%, respectively. Furthermore, CEUS detected SMV invasion in 26 cases (27.6%), while no invasion features in 68 (72.4%) cases. The sensitivity, accuracy, specificity, positive predictive value, negative predictive value for CEUS were 75.0%, 87.2%, 92.4%, 80.7%, 89.7%, respectively. Conclusion Due to its good diagnostic and predictive performance in detecting malignant pancreatic tumors and peripancreatic vascular invasion, CEUS could be served as an effective predictive modality in assessing the resectability of pancreatic carcinoma.
ABSTRACT
Objective To evaluate the association of the size of thyroid nodules and the diagnostic value of repeat fine needle aspiration cytology(FNAC) in diagnose of thyroid nodules.Methods One hundred and forty-three thyroid nodules in one hundred and thirty-five patients with repeat FNAC and thyroidectomy were retrospectively analyzed.The nodules were divided into three groups according to the largest diameter(L):GroupA,L＜0.5 cm;GroupB,0.5 cm≤L≤1.0cmandGroupC,L＞1.0cm.Yield of FNACs were divided into six levels according to the classification criteria of the Bethesda system,and Level Ⅰ,Ⅲ,Ⅳ,Ⅴ were defined as the indefinite cytological diagnosis.Results The diagnostic rate of repeat FNAC was obviously higher in group B compared with group A and group C,with significantly statistical difference (P ＜0.05).The risk of malignancy for persistently indefinite diagnostic aspirates after repeat FNAC was significantly reduced with statistical difference from the initial indefinite diagnostic aspirates in group B (P ＜0.05),while there was no statistical difference between group A and group C (P＞0.05).The diagnostic accuracy of repeat FNAC in group B was significantly higher than that in group A(P ＜0.05),but not in group C (P ＜0.05).Conclusions The repeat FNAC has a higher efficiency in those nodules with a largest diameter between 0.5 cm and 1.0 cm,and a repeat FNAC can be suggested.
ABSTRACT
Objective To evaluate the diagnostic value of puncture feeling combined with fine-needle aspiration cytology (FNAC) for thyroid nodules.Methods One thousand and fourteen thyroid nodules were retrospectively analyzed.Eighty-six thyroid nodules were performed repeat FNAC.All nodules were confirmed by pathology,the agreement of puncture feeling at different time was evaluated by Kappa test.Results There were 751 malignant nodules and 263 benign nodules.Sensitivity and accuracy of FNAC combined with puncture feeling were higher than those of single FNAC or single puncture feeling (x2 =11.609,4.433 and P =0.00,0.04;x2 =19.369,6.697 and P =0.00,0.01,respectively).There were no statistically differences in the sensitively and accuracy between single FNAC and puncture feeling (x2 =1.230,0.242 and P =0.27,0.62,respetively).The Kappa values of inter-observer and intra-observer were 0.829(P =0.00) and 0.885(P =0.00) respectively with statistically significance.Conclusions Puncture feeling combined with FNAC can improve the sensitivity and accuracy in the diagnosis of thyroid nodules,the reproducibility of puncture feeling is excellent.
ABSTRACT
Objective To investigate the expressions of microRNA-21,microRNA-143,and microRNA-145 in the sera of patients with nasopharyngeal carcinoma (NPC),and their assessment vales in the recurrence,metastasis,and prognosis of NPC patients.Methods From January 2012 to January 2014,80 NPC patients in our hospital Department of Internal Medicine and Head and Neck Surgery was used as tumor group,80 cases of healthy volunteers as control.The real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the expression levels of microRNA-21,microRNA-143,and microRNA-145 in the sera.Results Expression of microRNA-21 in NPC patients was significantly higher than that in healthy control group with statistically significant difference (P ＜ 0.05).The expressions of microRNA-143 and microRNA-145 in NPC patients was significantly lower than those in healthy control group with significant difference (P ＜ 0.05).At the same time,those microRNAs were significantly associated with tissue differentiation,invasion,and metastasis.Conclusions Increased microRNA-21 expression level in NPC patients,and decreased expression of microRNA-143 and microRNA-145 in NPC patients play an important role in differentiation,invasion,and metastasis in the development process of NPC.microRNAs can be used as a new index in the auxiliary diagnosis of NPC and the evaluation of recurrence,metastasis,and prognosis evaluation.
ABSTRACT
Objective To evaluate the diagnostic value of TSSC1 in glioma patients and its influence on cell biologi-cal behavior of glioma U87 cells. Methods RT-PCR and Western blot were used to examine the expression of TSSC1 in glioma samples, including 80 normal paraneoplastic tissues and 80 primary tumors. MTT and transwell were used to analyze the effect of TSSC1 knockout on proliferation, migration, and invasion in U87 cells. Results TSSC1 is down-regulated in glioma compared to its paraneoplastic counterparts and negatively related to higher grade. Furthermore, knockdown of TSSC1 expression results in increased proliferation, migration and invasion in U87 cells in vitro. Conclusion Our results may worked as a marker for early diagnosis and prognosis of glioma.
ABSTRACT
This study was aimed to observe the effect of Bu-Shen Huo-Xue Tong-Lin (BSHXTL) formula on gene expression of Caspase-3 in benign prostatic hyperplasia (BPH) rats. A total of 72 rats were randomly divided into the sham operation group, model group, proscar group, low-dose BSHXTL group, middle-dose BSHXTL group and high-dose BSHXTL group. The rat model was established by injecting testosterone propionate for 30 days after removing testis except the sham operation group. The drugs were administered once a day at the same time of the model establishment. Immunohistochemical method was used to measure positive average gray. And RT-PCR was used to measure the gene expression of Caspase-3.The results showed that compared with the model group, the expression of Caspase-3 and mRNA in each treatment groups were increased (P < 0.05). And the high-dose BSHXTL group was higher than the proscar group and low-dose BSHXTL group (P< 0.05). It was concluded that BSHXTL formula may upregulate gene expression of Caspase-3, which may be the mechanism of BPH treatment.
ABSTRACT
This study was aimed to evaluate the efficacy and safety of free-frying granules of traditional Chinese medicine(TCM) on treatment of chronic prostatitis. A total of 120 chronic prostatitis patients that were diagnosed with the dampness-heat and blood-stasis syndrome and kidney-deficiency syndrome were divided into the TCM group and western medicine group by random digit table. Category II and ⅢA chronic prostatitis were treated with oral administration of Levofloxacin Mesylate Tablets (0.2 g, bid) and the category ⅢB chronic prostatitis was treated with oral administration of Terazosin Hydrochloride Tablets (2 mg, qd). In the TCM group, the dampness-heat and blood-stasis syndrome was treated with Tongluo Qingjie formula ( which was self-made formula containing Rhizoma Dioscoreae Hypoglaucae, Herba Patriniae, Semen Plantaginis, and etc.) and the kidney-deficiency syndrome was treated with Jiawei Wuzhi Yanzong pills (which containing Semen Cuscutae, Chinese Wolfberry, Radix Rehmanniae Preparata, Fructus Rubi and Schisandra chinensis, and etc.). Four weeks was one course of treatment. The results showed that the total effective rate of TCM group was better than that of western medicine group (P< 0.05). Effect of TCM group was obviously better than that of western medicine group in the improvement of prostatitis NIH-CPSI score, the quality of life and symptoms of the patients. TCM may increase lecithin corpuscle in prostatic fluid of ⅢA chronic prostatitis (P< 0.05). Meanwhile, no obvious toxiferous and side reactions were found. It was concluded that the free-frying granules of TCM have good efficacy and safety in the treatment of chronic prostatitis.
ABSTRACT
This study was aimed to observe the effect of Bushen-Huoxue-Tonglin formula (BSHXTLF) on Ki-67 and apoptotic bodies in benign prostatic hyperplasia (BPH) rats. A total of 72 Wistar rats were randomly divided into 6 groups, which were the sham operation group, model group, Proscar group (0.8 mg?kg-1), BSHXTLF groups with low, middle and high dose (7.5, 15, 22.5 g?kg-1). Except the sham operation group, the BPH model was established by injecting testosterone propionate (5 mg?kg-1) for 30 days after removing both testicles in the rats. The drugs were administrated once a day for 30 days at the same time. The immunohistochemical and TUNEL methods were used to determine Ki-67 and apoptotic bodies, respectively. The results showed that compared with the model group , the expression of Ki-67 in treatment groups was decreased ( P < 0 . 05 ) . Compared with Proscar group and low-dose BSHXTLF group, the expression of Ki-67 in the middle- and high-dose BSHXTLF group was decreased ( P < 0 . 05 ) . Compared with the middle-dose BSHXTLF group , the expression of Ki-67 in the high-dose BSHXTLF group was decreased ( P < 0 . 05 ) . Compared with the model group , the expression of apoptot-ic bodies in each treatment group was increased ( P < 0 . 05 ) . Compared with Proscar group , low-dose and middle-dose BSHXTLF group, the expression of apoptotic bodies in the high-dose BSHXTLF group was increased (P <0.05). It was concluded that BSHXTLF may decrease the expression of Ki-67 and increase the expression of apoptotic bodies in BPH rats. These results provided objective evidences for clinical treatment of BPH.
ABSTRACT

ABSTRACT
This study was aimed to explore rules of classification and quantitative diagnosis of syndromes of as-thenospermia and oligospermatism on the basis of statistical analysis of the multi-factor. Factor analysis was used to analyze clinical symptoms of 507 patients. Scores were given according to the severity of symptoms. Five repre-sentative factors were extracted from the symptoms of asthenospermia and oligospermatism, which are the downward diffusion of damp-heat, kidney essence insufficiency, kidney yang deficiency, liver qi stagnation and kidney yin deficiency. Syndromes were quantized at the same time. Rules of syndrome sorting and quantitative diagnosis which come from large-scale sample provide evidences for clinical diagnosis of asthenospermia and oligospermatism.
ABSTRACT
Objective To study the role of Anopheles anthropophagus in malaria transmission and transmission threshold so as to provide basis for vector surveillance and malaria control strategy. Methods Parasitological and entomological methods were used in the investigation at 5 villages of Xinyang City, Henan Province. Results From July to August, 1999, 74 febrile cases (10^9% of the total population) were examined. Among them 50 were infected, the incidence in the population of surveyed spots was 7^4%. Active detection was made in another randomly selected two villages and found that the parasite rate in the inhabitants was 2^0%, and the positive rate of IFA was 8^4%. Only vivax malaria was detected. An.anthropophagus and An.sinensis were collected, with An.anthropophagus as the predominant one in human dwellings. The estimated man\|biting rate and the human blood index were 4^9388 and 0^7858 respectively. The vectorial capacity of An. anthropophagus was 5^5296. The critical man\|biting rate of An.anthropophagus was 0^2407 as calculated by the formula (ma=-rlnP/abP\+n) according to Macdonald′s model.The local man\|biting rate was 20 times higher than that of the critical man\|biting rate. Conclusion The results demonstrated that An.anthropophagus is the principal vector in malaria transmission in the area. The findings imply that the critical man\|biting rate is of practicable importance in vector surveillance.
