Objective To evaluate the clinical significance of serum procalcitonin (PCT)in early diagnosis of pul-monary tuberculosis (PTB)complicated with pulmonary infection.Methods Clinical data of active PTB patients admitted to a hospital between August and December 2013 were collected,patients were divided into bacterial infec-tion group(n=104),fungal infection group(n=37)and control group (n=95)according to whether patients were associated with bacterial infection,fungal infection,and without infection,serum PCT concentrations in three groups were compared,receiver operating characteristic (ROC)curve analysis was conducted.Results The median PCT concentrations in bacterial infection and fungal infection group was 0.44ng/mL and 0.30ng/mL respectively, which was significantly higher than 0.16ng/mL of control group(Z =9.49,3.51 respectively,both P <0.001 ).The area under curve (AUC)was 0.89(0.84-0.93)and 0.69(0.61 -0.77)respectively;cut-off point was 0.31 ng/mL and 0.27 ng/mL respectively;sensitivity was 79.81%(70.57%-86.80%)and 59.46%(42.19%-74.80%)respectively;specificity was 83.16%(73.79%-89.78%)and 73.68%(63.48%-81.95%)respectively.Conclusion PCT level is a valuable predictor for early diagnosis of PTB complicated with pulmonary infection,and can provide reference for the rational use of antimicrobial agents.

Objective To provide applied anatomic bases for the transplantation of scapular spine bone flap pedicled with supraspinous branch of suprascapular artery Methods The origin,course,branches and distribution were observed on 30 adult cadaver specimens;the operative designs were imitated on 6 specimens Results The supraspinous branch originated from suprascapular artery,went between supraspinatus muscle and scapular bone medially,and divided into 3～4 periosteal branches to scapular spine with a diameter of 0 5～0 8mm The length of stem of supraspinous branch was (4 8?0 6)cm Conclusions The transplantation of scapular spine bone flap pedicled with supraspinous branch of suprascapular artery is feasible

Objective:To study the effects of parathyroid hormone(PTH) upon dentinogenesis by investigating the effects of hPTH1-34 on the development and calcification of parathyroidectomy rats' dentin. Methods: hPTH1-34 were injected into SD rats at different dosages after parathyroidectomy. Six weeks later lower incisors were dissected and prepared for light microscopy and image analysis. Results:The concentration of serum calcium decreased after parathyroidectomy, while increased after being injected hPTH1-34. The results of light microscopy and image analysis revealed the enlargement of the predentinal tubules and the presence of mineralization defects in the PTX group(P

0.05). Conclusions Carbon dioxide pneumoperitoneum during retroperitoneoscopy has no obvious influence on hepatic functions, renal functions and myocardial enzymogram. It may not cause significant damage to patients with normal heart, hepatic, and renal functions.

OBJECTIVE: To compare the content of gastrodine in wild and cultivated Gastrodia elata from different habitats in Guizhou province in order to provide scientific reference for cultivation of G.elata.METHODS: Samples were extracted from G.elata with microwave.RP-HPLC method was used to determine the content of gastrodine in G.elata.RESULTS: The content of gastrodine in wild G.elata was higher than that in cultivated G.elata.The contents of gastrodine in wild G.elata were different from one another while the contents of gastrodine in cultivated G.elata hadn’t obvious differences.CONCLUSION: The quality of wild G.elata is superior to that of cultivated G.elata.The study provide scientific basis for the cultivation of G.elata.

Objective To establish an in vitro skin sensitization test,human cell line activation test (h-CLAT),based on THP-1 cell line (a human acute monocytic leukemia cell line),and to assess the sensitizing potency of plant raw materials of chemical and cosmetic products by this in vitro skin sensitization test.Method THP-1 cells were cultured in vitro and exposed to 11 reference skin sensitization chemicals and 9 samples,by monitoring the cell viability,cell surface marker CD54 /CD86 and relative fluorescence intensity of cells surface after the cells was exposures to the substances,and to discover whether there is a positive reaction.At the same time,Buehler test was used to validate the results of samples tested by h-CLAT.Results 11 reference chemicals were distinguished correctly by h-CLAT.Among the 9 samples tested,7 samples were recognized as negative sensitizer and 2 plant extracted substances were identified as suspicious skin sensitizer.The qualitative classification of the 9 samples by h-CLAT test was consistent with the results obtained by animal test.Conclusions The h-CLAT-in vitro test can be used to replace some animal tests for the prediction of soluble skin sensitizing substances.

Objective To improve quota-sampling precision and reproducibility of the impedance blood rheometer. Methods Quota-sampling control circuit and the sampling needle's structure were improved for the early MVIS blood rheometer. The parameters of sampling were analyzed. Results After the improvement, the sampling errors were reduced obviously (less than ?3%). The quota-sampling handling was more accurater. Conclusion The precision and reproducibility of the blood rheometer are ensured.

Objective To discuss the clinical value of transposition of the pedicled anterolateral femoral periosteal flap. Methods The blood supply of anterolateral femoral periosteum were dissected on 38 adult cadaveric lower limber specimens injected with red dye. The origins, distributions and anastomosis of periosteal breanches were observed and measured. Based on these anatomic investigations, the transposition of pedicled anterolateral femoral periosteal flap was designed to repair the bone nonunion and lesion of femur. Results Twenty-two cases were treated in the satisfactory results, and followed-up from 1 to 5 years. The size of the periosteal flap ranged from 8cm?4cm to 10cm?5cm. Conclusions The periosteal flap could be operated so conveniently and safely as to be spread easily, treatment of lesion and incision of periosteal flap can be finished in the same operative approach. The periosteal flap have been proved to be powerfully clinical value.

Sialolithiasis is a common disease of the salivary gland. This disease mainly involves the major salivary gland. Sialolithiasis of the minor salivary gland is rare. A case of sialolithiasis of the upper lip was reported, and relevant literature was reviewed in this paper.

Objective To study the quick triage assessment system for emergency nurse, establish evaluation model and method, select indicators and contents, guide triage nurses to be accurate, fast, convenient and practical, and also to optimize the use of emergency medical resources. Methods Screening the target population to conduct the research, collecting main indicators and features covered with main symptom and characteristics of severe critical emergency patients, selecting manifestation form of triage assessment system. Results The selected indicators and contents were demonstrated by a table-based form, and the quick triage assessment form for emergency nurse was established to instruct triage work. Conclusions This established quick triage assessment form is simple, intuitive and can improve the quality of emergency triage work. It possesses feasibility, practicality and achieves the optimal medical services with the limited emergency medical resources, which shows both social and economic effect.
