Objective To obtain the gene fragment encoding human mannan-binding lectin (MBL)-associated serine protease-2 (MASP-2). Methods The target cDNA fragment was amplified from the total RNA extracted from human fetal liver tissue by RT-nested PCR, cloned into pGEM-T vector and identified by restriction analysis and sequencing. Results The cDNA fragment encoding MASP-2 polypeptide with the signal sequence was isolated, linked with pGEM-T vector and transformed into E.coli TG1. The restriction maps of the selected clones were consistent with those generated by computer analyses. The result of sequencing of one selected clone showed that its sequence was identical with that of reported human MASP-2 cDNA. Conclusion The human MASP-2 gene was successfully cloned, which prepares the ground for studying the molecular mecha- nisms by which MBL activates the complement lectin pathway and the mutations of MBL gene cause immunodeficiency.

Objective To investigate current status of narcotic analgesic use in patients with cancer pain in our hospital, in order to promote the rationalization of prescribing narcotic drugs and the rational use of analgesics. Methods A total of 400 narcotic prescriptions ( 100 of outpatients and 300 of inpatients ) in Tongji hospital were randomly selected from March to May in 2014.Basic index and consumption of anesthetic drugs, money consumption distribution on different tumor types, and unreasonable prescription were analyzed. Results The overall prevalence of irrational prescriptions was 11. 00%, with 13.00% from inpatient and 10. 33% from outpatient, respectively. Reasons for irrational prescriptions mainly included vague instructions on dosage and administration, incomplete clinical diagnosis, lack of pharmacist check and inappropriate dosage. In the basic indexes, proportions of reasonable prescription and drugs within the national formulary were higher in the inpatient than in the outpatient service.The average money consumption of outpatient prescription was significantly higher than that of inpatient prescription.Most types of diagnosis were lung cancer in outpatient and inpatient departments, and total cost of lung cancer drugs was the highest.Morphine hydrochloride of outpatient had the highest average consumption, followed by codeine phosphate of the outpatient and the inpatient, and oxycodone hydrochloride controlled-release tablets cost more in inpatient. Conclusion The narcotic analgesic used in our hospital is basically rational. Most doctors prescribe according to the guidelines, but standardized training of prescription for cancer patients with pain medication needs to be strengthened, and supervision of narcotic analgesic medication should be enhanced.

OBJECTIVETo analyze the expression and clinical values of HPV L1 capsid protein and p16INK4a protein in uterine cervical lesions.

METHODSFifty-four cervical intraepithelial neoplasias CIN1, 44 CIN2, 78 CIN3, and 48 squamous cell carcinoma were included in this study. All CIN and squamous carcinomas were stained with anti-HPV L1 capsid protein antibodies and anti-p16INK4a antibody. Forty-five CIN1 patients were followed up for 6 years.

RESULTSForty-five CIN1 patients were followed up for 6 years, among them 6 cases showed a progression (One case changed to CIN3, 5 cases to CIN2). L1 positivity was found in 50 cases which decreased with CIN increasing (χ(2) = 259.923, P < 0.001) while p16INK4a positivity was found in 177 cases which co-increased with CIN (χ(2) = 48.842, P < 0.001). L1(-)p16INK4a (-) or L1(+)p16INK4a(-) appeared mainly in CIN1 while L1(-)p16INK4a(+) appeared mainly in CIN2 lesions. No progression was found in the group of L1(-)p16INK4a(-) CIN1 patients. The risk of CIN1 progression in L1(-)p16INK4a(+) group was 66.7% while L1(+)p16INK4a(-) group was 9.5%, and L1(+)p16INK4a(+) group was 33.3%.

CONCLUSIONSThe expression of p16INK4a together with HPV L1 are different in various cervical lesions, and the combined detection of p16INK4a and HPV L1 can be helpful for estimating the biological potentiality of CIN lesions.

OBJECTIVETo summarize the therapeutic experience and analyse the clinical effects of anatomical plate and combined external fixator for the treatment of elderly intertrochanteric hip fractures.

METHODSFrom Oct.2006 to Jun.2009, 42 patients with intertrochanteric hip fractures were treated. Among them, 19 patients were treated with combined external fixator, included 7 males and 12 females, aged from 71 to 103 years old; according to Evans classification there were 3 of type 1, 5 of type II, 6 of type III, 5 of type IV. The other 23 patients were treated with anatomical plate, included 9 males and 14 females, aged from 73 to 97 years old; there were 5 of type I , 4 of type II, 10 of type II, 2 of type IV, 2 of type V. Comparisons and statistical analysis were made on operation time, blood loss during operation, hospitalization time, the time of loaded walking, fracture healing time and therapeutic effect.

RESULTSAll the patients were followed up for 6 to 15 months with an average of 8.6 months. In combined external fixator group, the average operation time was (29.368 +/- 3.253) min, the average blood loss during operation was (30.526 +/- 5.242) ml, the average hospitalization time was (4.368 +/- 1.165) d, the average time of loaded walking was (14.526 +/- 1.867) weeks, the fracture healing time was (14.632 +/- 2.798) weeks; in the anatomical plate group above-mentioned indexes were (58.987 +/- 8.600) min, (256.090 +/- 30.112) ml, (13.783 +/- 1.976) d, (11.391+/- 1.644) weeks, (11.391 +/- 2.327) weeks,respectively; and there were significant differences between two groups (P<0.05). According to Harris score criterion, the scores of combined external fixator group was (86.368 0 +/- 3.640) scores,and the scores of anatomical plate group was (86.435 +/- 4.198) scores; there were no significant differences between two groups (P>0.05).

CONCLUSIONThe effect of combined external fixator and anatomical plate for the elderly intertrochanteric hip fractures are both satisfactory and each has its own merits. Combined external fixator has advantages such as fewer complications and operative injuries than that of anatomical plate and is more suitable for the weaker with elderly intertrochanteric hip fractures.

Hot-melt extrusion was applied to prepare mesoporous silica/ethylcellulose mini-matrix for sustained release, and fenofibrate was used as a model drug, ethylcellulose and xanthan gum were chosen as sustained-release agent and releasing moderator, respectively. This novel matrix obtained the controlled release ability by combining mesoporous silica drug delivery system and hot-melt extrusion technology. And mesoporous silica particle (SBA-15) was chosen as drug carrier to increase the dissolution rate of fenofibrate in this martix. Scanning electron microscope, transmission electron microscope, small angle X-ray powder diffraction and N2 adsorption-desorption were introduced to determine the particle morphology, particle size and pore structure of the synthesized SBA-15. The results showed that SBA-15 had a very high Brunauer-Emmett-Teller specific surface area, a narrow pore size distribution, large pore volume and a ordered two-dimensional hexagonal structure of p6mm symmetry. Differential scanning calorimetry and X-ray powder diffraction results demonstrated that fenofibrate dispersed in an amorphous state inside the pores of the mesoporous silica which contributed to the improvement in the dissolution rate. The drug release of mini-matrices was influenced by ethylcellulose viscosity grades and xanthan gum concentration, which increased with the increasing of xanthan gum concentration and decreasing of ethylcellulose viscosity. Mini-matrix containing 22% xanthan gum exhibited a good sustained release performance, and the drug release behavior followed the first-order kinetics.

A field trial was carried out to study the influence of different kinds of spring topdressing on growth, yield and quality of Ligusticum chuanxiong. The results showed that the spring topdressing had effects of improving root length, tiller numbers and plant height to some extent. At the same time the chlorophyll content and dry weight accumulation especially the dry weight of root increased significantly. It also showed that the yield increased and quality was improved significantly. The effect of different treatment with urea58.7 kg x hm(-2)(N 27 kg x hm(-2)) was the best and the treatment with N,P,K the second.
