Microwave-assisted extraction (MAE) was used for extraction of effective components of sarcandra glabra (Thunb.), and then chromatographic fingerprint of sarcandra glabra (Thunb.) was studied by high performance liquid chromatography/diode array detector (HPLC/DAD). The conditions of MAE were optimized by an orthogonal experiment, and then the authentication and validation of the chromatographic fingerprint were conducted. Nine peaks were identified as common peaks in the fingerprint chromatograms, and isofraxidin was considered as a reference compound and quantified. Relative standard deviations of retention time and peak area of each component were less than 3 % and 8 %, respectively. Similarity and difference analysis were conducted by use of PCA and relation coefficient. Twenty batches of sarcandra glabra (Thunb.) samples from two different producing areas could be classified into two different groups in the PCA model. The results showed that MAE-HPLC/DAD method was simple, efficient and stable for the study of complex chromatographic fingerprint of sarcandra glabra (Thunb.), which could provide more reliable and precise information for quality evaluation.

To investigate the clinicopathological features of endometrial endometrioid adenocarcinoma(EEA)with adnexal involvement.Methods The clinicopathological data of 86 EEA patients who underwent surgical treatment at our center from January 2000 to December 2015 were analyzed retrospectively.The clinicopathological features were compared between patients with occult adnexal involvement and those with gross adnexal involvement.Results A total of 86 EEA patients with adnexal involvement(mean age:58.1 years)were included in this study,accounting for 5.4%(86/1592)of the EEA patients during the same period.Among these 86 patients,there were 13 premenopausal patients(15.1%)including 2 premenopausal patients aged under 40 years.Gross adnexal involvement was found in 47 patients(54.7%),while occult adnexal involvement was found in 39 patients(45.3%)in pathology evaluation.Ovarian metastasis was found in 34 patients(39.5%),followed by both ovarian and tubal metastasis in 19 patients(22.1%)and tubal metastasis in 33 patients(38.4%).The expressionss of estrogen receptor(χ=8.086,P=0.042)and progesterone receptor(PR)(χ=9.149,P=0.026)were significantly different between gross adnexal involvement group and occult adnexal involvement group,whereas no significant difference was found in other clinicopathological features(all P>0.05).The non-conditional Logistic regression analysis showed that,compared with PR no-expression group,the rate of occult microscopic adnexal involvement in PR low-expression group was 6.375 times of that of the gross adnexal involvement(P=0.005,95%CI:1.768-22.976),and the rate of occult microscopic adnexal involvement in the PR high-expression group was 3.719 times of that of gross adnexal involvement(P=0.048,95%CI:1.009-13.702). Conclusion PR expression level is remarkably lower in EEA patients with gross adnexal involvement than those with occult adenxal involvement.

Enhanced green fluorescent protein( EGFP), myc epitope and polyhistidine metal-binding tag are often used as a marker for recombinant fusion protein in many gene expression vectors, each marker has its own function, EGFP emits green fluorescence for direct detection, myc epitope facilitates recombinant fusion protein detection using its antibodies, polyhistidine tag allows purification of recombinant fusion protein using resin.Hitherto, no a plasmid vector can integrate all of these functions. In this study we constructed a novel eukaryotic expressive plasmid, designated as pcDNA6/myc-his-EGFP B, which integrated the functions of EGFP, myc epitope and polyhistidine tag. Importantly, a linker octo - peptide in N terminal of EGFP was designed using LINKER program. A DNA fragment encoding a putative protein containing a signal peptide of human interleukin 2(IL-2) in N terminal was cloned into pcDNA6/myc-his-EGFP B in frame with the C-terminal peptide to construct pMHES. 2.2.15 Cells were transfected with pcDNA6/myc-his-EGFP B and pMHES, and Balb/c mice were intravenously injected with pcDNA6/myc-his-EGFP B by tails, results revealed that both of the plasmids worked in 2.2.15 Cells and livers of Balb/c mice. Assuming gene of the IL-2 was inserted into pcDNA6/myc-his -EGFP B in frame with EGFP, myc and 6 × His, three-dimensional structure for this putative expression product was simulated using Modeller8V2, results revealed that IL-2, EGFP, myc and 6 × his did not interfere each other and octo- peptide linker owned certain flexibility. The results suggest that pcDNA6/myc-his-EGFP B may be useful as a genetic tool for mammalian cells and a vector for gene therapy.

SUMMARY To explore the clinical pathological characteristics and improve the recognition in the diag-nosis and treatment of basal cell carcinoma (BCC)of prostate.Three cases of BCC of prostate were re-ported and the relevant literature was reviewed to investigate the diagnosis and treatment of this disease. We analyzed three cases of prostatic BCC.Their ages were within a range of 57 to 83 years.One of them complained of hematuria and two complained of dysuria.All of them presented with prostatic hyperplasia. Two of them presented with high prostate specific antigen (PSA)and one with normal PSA.Case 1 had prostate cancer invasion of bladder,rectal fascia,with lymph node metastasis,bone metastasis and lung metastases.The patient received bladder resection +bilateral ureteral cutaneous ureterostomy +lymph node dissection on November 2,2014 .Postoperative pathological diagnosis showed BCC.Reexamination of pelvic enhanced MRI in January 8,2015 suggested pelvic recurrence.Abdominal enhanced CT showed multiple liver metastases and pancreatic metastasis on July 11,2015.Prostate cancer specific death occurred in October 2015.Case 2 was diagnosed as BCC in prostate biopsy on March 27,2015. Positron emission tomography and computed tomography (PET-CT)showed pulmonary metastasis and bone metastasis.Then the patient received chemotherapy,endocrine therapy and local radiation therapy. Reexamination of PET-CT on January 11,2016 showed that the lung metastase tumors and bone metas-tase tumors were larger than before.Up to January 10,2016,the patient was still alive.Postoperative pathological changes of transurethral resection of prostate (TURP)in case 3 showed BCC might be con-sidered.The PET-CT suggested residual prostate cancer,which might be associated with bilateral pelvic lymph node metastasis.In April 20,2016,the review of PET-CT showed pelvic huge irregular hybrid density shadow,about 14.5 cm ×10.0 cm ×12.9 cm in size,and tumor recurrence was considered. Then the patient received local radiation therapy.The patient survived in the followed upon January 10, 2016.BCC of prostate is a rare subtype.Due to the local infiltrative and distant metastatic potentiality, active management is preferred and a life-long follow-up is necessary.

Objective:To compare the effectiveness of fire needle versus Western medicine in the treatment of herpes zoster. Methods:Randomized controlled trials comparing fire needle with Western medicine in the treatment of herpes zoster were identified using 8 databases. A meta-analysis was performed using RevMan 5.3 software. Results:Eight trials involving 569 patients were included in this meta-analysis, and the results showed that fire needle was superior to Western medicine comparing the effective rate [risk ratio (RR)=1.13, 95％ confidence interval (CI): 1.06 to 1.20;P=0.0002], the visual analog scale (VAS) score [mean difference(MD)=–7.95, 95％ CI: –10.71 to –5.20;P<0.00001], time of pain disappearance (MD=–7.61, 95％CI: –9.38 to –5.84;P<0.00001), time of blister-stop (MD=–1.34, 95％CI: –1.51 to –1.18;P<0.00001), time of crusted scab (MD=–2.92, 95％CI: –3.62 to –2.23;P<0.00001), and time of scab off (MD=–4.64, 95％CI: –5.83 to –3.46;P<0.00001). In addition, a significantly lower incidence of postherpetic neuralgia was found in the fire needle group in 30 d (RR=0.23, 95％CI: 0.11 to 0.51;P=0.0002) and 60 d (RR=0.33, 95％CI: 0.12 to 0.91; P=0.03) after treatment. Conclusion:Fire needle has a favorable effect in increasing the effective rate, relieving pain, recovering skin lesions and decreasing incidence of postherpetic neuralgia in the treatment of herpes zoster. However, considering the limitations in this study, the findings should be interpreted cautiously.

Dedifferentiated chondrosarcoma (DDCS) is a rare but highly malignant primary bone neoplasm, which is resistant to radiotherapy and chemotherapy. There remains uncertainly as to the best treatment of this disease and how to improve its prognosis. In this paper we reported a case of DDCS and reviewed the related literatures in order to provide references to throw a light on the histogenesis, diagnosis and therapy of this disease.
