Purpose To study the cytopathologic features of CT-guided percutaneous lung biopsy samples and to evaluate the role of cytopathology in the diagnosis and staging of lung carcinomas, as compared to histopathology. Methods Four-hundred twenty-five specimens were collected by CT-guided percutaneous lung biopsy which were also confirmed by histological diagnosis. Direct smears were performed for each case. Cytological and histological examination was carried out. Results The sensitivity, specificity, false positive rate, false negative rate and accuracy of cytopathology in diagnosing lung carcinomas by CT-guided percutaneous lung biopsy was 86. 6% (264/305), 100% (120/120), 0 (0/120), 13. 4% (41/305), 90. 4% (384/425), respectively. Overall 51. 1%(135/264) of the cases were precisely typed, including 77. 6% (83/107) of adenocarcinoma, 76. 9% (40/52) of squamous cell car-cinoma and 75. 0% (9/12) of small cell carcinoma. Conclusions Cytopathology of CT-guided percutaneous lung biopsy specimens is sensitive and accurate for diagnosing pulmonary carcinomas. In some cases, the lung carcinoma can be precisely typed. Therefore, it is useful for diagnosing and staging lung carcinomas.

Small RNA (miRNA) can regulate post-transcriptional level of mRNA. miRNA is closely related to the occurrence and development of a variety of human diseases such as gastric cancer, lung cancer, breast cancer, ovarian cancer, prostate cancer, pancreatic cancer, liver cancer, etc. Many kinds of miRNAs in human cancers are significantly abnomadly expressed. miRNA can be regarded as a marker for many human cancers diagnosis.

OBJECTIVETo evaluate the effect and safety of Chinese herbal medicine Lingdankang Composite (LDK) combined dendritic cell-cytokine induced killer cells (DC-CIK) in treating leukemia.

METHODSSubjects were selected from leukemia patients who achieved hematological complete remission (HCR) but not achieved molecular biological remission (MBR), or with minimal residual leukemia (MRL) positive. Twenty patients, 19 of acute leukemia and 1 of chronic myelocytic leukemia, were enrolled. DC and CIK from patient's peripheral blood monocyte were separated respectively by blood cell separator, then DC-CIK was obtained through respective culture followed with mixed cultivation of them, and was infused back to the patient self via intravenous injection. The back infusion of DC-CIK was performed once every 15-20 days for 4-6 times in total. Meantime, LDK was administered orally every day.

RESULTSIn the 20 patients treated, 4 case of HCR achieved MBR, the negatively reversed marker gene was AML1/ETO in 1 case, CBFbeta/MYH11 in 1, bcr/abl in 1, and the other 1 was IgH gene rearrangement; 3 patients with positive MRL were reversed to negative. The 3-year CR rate was 75% with a medium CR period of 25 months (10-37 months). Except transient fever and chill in 5 cases, no other remarkable adverse reaction happened during or after DC-CIK infusion.

CONCLUSIONThe combined treatment of LDK and autologous DC-CIK in treating patients with HCR shows an obvious effect of clearing MRL, it is the appropriate choice for curing leukemia of HCR, and is safety for intravenous infusion, so it has potential clinical prospect.

AIM:To study the effect of berberin hydrochloride(Ber)on the elevation of blood concentra- tion of Cyclosporin A(CsA)and liver and renal functions in renal transplanted recipients.METHODS:138 cases with renal transplantation in experimental group were treated with CsA and Ber and 150 cases with renal trans- plantation in control group received CsA only.Blood lev- els of CsA,biochemistry indexes for liver and renal func- tion were determined.RESULTS:After 1,3,6 months combined with Ber,blood concentrations of CsA in pa- tients went up by 49.8%,81.4%,36.9% and the radios of blood concentration of CsA to CsA dosage increased 88.8%,102.0%,72.5% compared with those before taking Ber(P

Objective To discuss the diagnostic value of contrast-enhanced ultrasonography in differentiating benign and malignant tumor of pelvic cavity.Methods From October 2014 to January 2016,abdominal ultrasonography or trans-vaginal ultrasonography were performed among outpatients and inpatients in the First Affiliated Hospital of Kunming Medical University.We found 62 cases with pelvic cavity tumors with 64 lumps,which were detected at cystic mass,cystic-solid mass,and solid mass in conventional ultrasonography.We made the diagnosis of all the lumps by performing contrast-enhanced ultrasonography,observing the infusion process and analyzing perfusion pattern,the intensity of perfusion and time intensity curve.By contrasting the diagnosis and the pathologic and long-term follow-up results,we classified the tumors into two groups,benign and malignant.Then we analyzed the time intensity curve and imaging parameters of the two groups.Restlts Among the total 64 lumps,43 was found in the group of benign tumor and 21 in the group of malignant tumor.Sixty-two were proved by pathologic results and 2 were proved by long-term follow-up results.Benign tumors showed that the infusion flowed from the peripheral to the center and enhanced equably and the vessels were regularly shaped.Malignant tumor showed that the infusion infiltrated from the center to the peripheral and enhanced quickly and unequally,and vessels were distorted.In the time intensity curve,group of benign tumors presented a gently slow raise and fall type,and group of malignant tumors showed a quickly raise and fall type.Rise time (RT) of malignant group (7.70 ± 2.56s) was shorter than benign group (11.40 ± 6.77s) (P＜0.05).Peak intensity (PI) of malignant group (16.30 ± 7.41dB) was higher than benign group (12.12 ± 6.70dB) (P＜0.05).Area Under the Curve (AUC) of malignant group (981.65 ± 548.04 dB s) was bigger than benign group (715.22 ± 651.04dB s) (P＜ 0.05).No difference was found between two groups in Time to Peak (TP) and Mean Transit Time (MTF) (P＞ 0.05).The sensitivity,specificity,positive and negative predictive value of contrast-enhanced ultrasonography were 95.2％,93.0％,86.9％,and 97.5％ respectively.Conclusion Contrast-enhanced ultrasonography ean show an eligible blood perfusion and vascularity of lumps.Analyzing perfusion pattern,time intensity curve,and other parameters can improve capacity of diagnosing and differentiating benign tumor and malignant tumor of pelvic cavity.

AIM: To evaluate the effects of the extract of Buddleja officinalis eye drops in basic tears secretory volume, tear film stability, expression of androgen receptors(AR) in castrated rats with dry eye, and to investigate the therapeutic effects of extract of Buddleja officinalis on dry eye caused by gonadal hormones level imbalance. METHODS:A total of 45 Wistar masculinity rats were divided at random into 9 groups, including normal group(A1,A2 and A3), model group(B1,B2 and B3), therapy group with extract of Buddleja officinalis eye drops(C1,C2 and C3). The "1" stood for being fed for 1 month, and "2" for 2 months, and "3" for 3 months. The dry eye model was established with orchiectomy on group B,C. Group C was treated with Buddleja officinalis extract eye drops for one month. All rats were checked with Schirmer Ⅰ test (SⅠt) and tear film break-up time (BUT). Expression of AR was analyzed by flow cytometer(FCM). RESULTS:The SⅠt value of group C was significantly higher than that of group B (P<0.01) and the BUT value of group C was significantly longer than that of group B (P<0.01), which indicated the eye drop could significantly keep basic tears secretory volume and tear film stability. And the expression of AR of group C was much higher than that of group B,which showed that available composition of the eye drops maybe display androgen-like activity.CONCLUSION:The main components of extract of Buddleja officinalis is the flavonoids which could significantly inhibit happening of dry eye of rat after androgen level lowered. Its mechanism is like androgen's and it could display androgen-like activity to keep basic tears secretory volume and tear film stability.
