OBJECTIVETo summarize the experience of percutaneous fixation of scaphoid fractures with Herbert screws through volar approach, and provide a reliable and efficient treatment method for scaphoid fractures.

METHODSFrom April 2008 to September 2012,15 patients with scaphoid fractures were treated by percutaneous fixation with Herbert cannulated screws through volar approach including 14 males and 1 female with an average age of 35 years ranging from 25 to 45 years old. Among them, 10 cases were on left side and 5 cases were on right side. Durations from injury to operation ranged from 3 to 10 days with an average of 5 days. All these cases were identified as B2 type according to the Herbert classification based on X-ray and CT scan. In order to assess the function of wrist, all patients were calculated according to Krimmer's score postoperatively.

RESULTSThe follow-up period were from 5 to 18 months with an average of 10 months. At 3 months after operation,X-ray was re-checked every month. All the patients achieved bone union with a mean time of 10 weeks (ranged from 7 to 14 weeks) postoperatively. According to Krimmer's score, 14 cases gained 100 scores as perfect and one case got 90 scores as good. The small volar incision of all patients were union at the first period. No operation complications such as infection and nonunion occurred.

CONCLUSIONPercutaneous fixation with Herbert cannulated screws through volar approach is a reliable and efficient treatment method for scaphoid fractures with small invasion, high bone union rate, and fewer complications.

Objective To study the susceptibility of Mycoplasma hominis(Mh) to several antimicrobials and Chinese medicinal herbs. Methods The minimal inhibitory concentrations(MIC) of Mh to 11 antimicrobials and 19 herbs were detected by the method of liquid microdilution. Results The sensitivity of Mh to those antimicrobials from high to low, was as follows:lincomycin, tetracycline, minocycline, levofloxacin, ciprofloxacin, ofloxacin, rifampin, spiramycin, azithromycin, erythromycin ethyl succinate and erythromycin. Among 19 herbs,Mh was sensitive to Radix Isatidis, Radix Angelicae Dahuricae, Cortex Phellodendri, Rheam Officinale, Fructus Kochiae and Herba Houttuyniae. Conclusions The susceptibility of local isolates of Mh to common antimicrobials is found out. Six Mh sensitive Chinese medicinal herbs are screened. The study provides evidences of treating Mh infection by combination of antimicrobials with Chinese medicinal herbs.

Background and purpose:Neoadjuvant chemotherapy to breast cancer has become a mature treat-ment method. The purpose of this study was to evaluate the dynamic contrast-enhanced MRI in assessing the response to neoadjuvant chemotherapy (NAC).Methods:Twenty-four female patients with breast carcinoma (24 were all inva-sive ductal carcinoma) underwent dynamic contrast-enhanced MRI (DCE-MRI) before, after the second and ifnal cycle of NAC. For each patient and each MRI examination, the maximum diameter of tumor, volume transfer constant (Ktrans), exchange rate constant (Kep), and extravascular extracellular volume fraction (Ve) were compared. According to the method of response evaluation criteria in solid tumor (RECIST), the results of neoadjuvant chemotherapy were divided into responder and non-responder.Results:All 24 patients were unilateral and single breast cancer; there were 17 cases of responders and 7 cases of non-responders according to RECIST criteria. For 17 cases of responders, both the average values ofKtrans andKepwere signiifcantly descended after neoadjuvant chemotherapy (allP<0.05).Conclusion:The quantitative parameters ofKtrans andKep can evaluate objectively and veridically the response to neoadjuvant chemother-apy for breast cancer in dynamic contrast-enhanced MRI.

Objective To investigate the factors affecting the recovery of immunological function after bilirubin decreasing interventional therapy in patients with obstructive jaundice.Methods 67 patients with malignant obstructive jaundice were investigated.The patients were randomly divided into the enteral nutrition (EN) group (n =34)and the parenteral nutrition (PN) group (n =33).TBIL,DBIL,TSP,ALB,PA,TF,CD3 +,CD4 +,CD8 +,CD4 +/CD8 + were determined before PTCD and at the 7th day after the procedure.Results Except for 20 patients,the levels of TBIL,DBIL,CD8 + significantly declined,and the levels of TSP,ALB,PA,TF,CD3+,CD4+,CD4+/CD8 + significantly increased in the 2 groups of patients.There was no significant difference in the recovery of liver function and immunological status between the PN and the EN groups.Conclusions The recovery of immunological function was significantly associated with reduction of serum bilirubin in patients with malignant obstructive jaundice.There was no relationship with the ways of nutrition support.

Objective: To obtain the transcriptome sequence database and differentially expressed genes of Asarum sieboldii, and to identify the genes related to the biosynthesis of methyleugenol, the main chemical compound in this species. Methods: Roots and leaves of the plants were chosen as experiment materials. The transcriptome sequence database was constructed by applying an Illumina Hiseq 4000 Sequencing Platform. Unigenes were assembled by BLAST similarity searches and annotated with GO and KEGG orthologs identifiers. Moreover, differentially expressed genes were analyzed. Results: 12.25 Gb database was obtained, among which 129 003 unigenes were annotated to be involved in 52 GO-terms and 363 metabolic pathways. After analysis, 439 differentially expressed genes were observed, the up-regulated genes account for 38.3% and the down-regulated genes account for 61.7%. In addition, 136 unigenes involved in phenylpropanoid biosynthesis in A. sieboldii, and 44 unigenes that were associated with biosynthesis of methyleugenol were identified.

Aim To evaluate the effects of notoginsen-oside R1 on store-operated calcium entry ( SOCE ) in pulmonary arterial smooth muscle cells ( PASMCs ) of chronic hypoxia ( CH)-and monocrotaline ( MCT)-in-duced pulmonary hypertension ( PH) rats. Methods Mn2+ quenching of Fura-2 and measurement of intra-cellular free calcium concentration ( [ Ca2+] i ) using fluo-3 were examined in PASMCs of CH-exposed and MCT-treated rats. Results ①CH-exposed and MCT-treated rats exhibited profound PH when examined 3 weeks after hypoxia exposure or MCT injection, respec-tively. ②In the presence of 3 μmol·L-1 nifedipine, 10 μmol · L-1 notoginsenoside R1 significantly re-duced cyclopiazonic acid ( CPA )-induced the percent reduction in Fura-2 fluorescence measured 500 sec af-ter application of Mn2+, the maximal rate of Mn2+quenching, the amplitude of the Ca2+ influx transient and the resting [ Ca2+] i in PASMCs of CH-exposed and MCT-treated rats. Conclusion Notoginsenoside R1 inhibits SOCE and reduces resting [ Ca2+] i in PASMCs of CH-and MCT-induced PH rats.

The herbs used as the material for traditional Chinese medicine are mostly planted at mountain areas where there is appropriate weather condition. Due to the complex terrain condition in mountain area, the planting at such places is always associated with a scattered pattern, which inevitably bring difficulty to the work of accurate measurement for the planting area. Advanced research about monitoring the planting area for medicine-herb under complex environmental condition is so critical and meaningful for developing the medicine-herb planting to a large scale and an industry. Therefore, this research, taking the planting of Herpetospermum pedunculosum in Luding county as an example, utilizes RS&GIS: using the image data from TM and ETM datum as the remote sensing information source, integrating GPS data from quadrat survey on the spots, and analyzing on a GIS platform, to extract the planting area of H. pedunculosum in Luding county. The results indicate that: (1) the method and technology used to estimate the planting area of H. pedunculosum are feasible and can be applied to monitoring the planting area of medicine-herb at mountain area under complex environmental conditions: (2) the planting area of H. pedunculosum in Luding county is estimated to be 857. 246 acres by the methods utilized in this research, which is closed to the value from local statistical data with an error range less than 5%; (3) in consideration of those inevitable errorrs generating from the procedures such as remote sensing data acquisition, data preprocessing, data interpretation, and so on, and the fact that the classification of remote sensing data, which must be implemented by those above procedures, was used directly to extract the herb type, the accuracy of area estimation for the herb is significantly influenced by the accuracy of classification for herb type, and the estimated area is inevitably associated with some error.
