The purpose of this study is to systematically investigate the characteristics of absorption and metabolism of oxymatrine (OMT) using rat intestinal perfusion model. Ultra performance liquid chromatography (UPLC) and high performance liquid chromatography-electrospray ionization-quadrupole-time of flight mass spectrometry (HPLC-ESI(+)-Q-TOF-MS) were used to test absorption of OMT in intestine at 100, 200 and 400 µmol · L(-1). The absorption rate and permeability of OMT is not dependent on concentration, but through passive absorption in intestine (P > 0.05). In the rat intestine, the absorbed amount of OMT was significantly different in four sections of the intestine in an order of duodenum > jejunum > ileum > colon (P < 0.05). OMT is metabolized into two metabolites in duodenum and jejunum, and matrine (MT) is the major one.

OBJECTIVE:
To detect potential mutation in a Chinese pedigree affected with congenital limb malformations.
METHODS:
Clinical data was collected. Genomic DNA was extracted from peripheral blood samples of family members. The zone of polarizing activity regulatory sequence (ZRS) were amplified by PCR and subjected to direct sequencing.
RESULTS:
Among the 13 individuals in this pedigree, there were 4 PPD patients, who were characterized by varying degrees of deformity. The female patients suffered triphalangeal thumb and preaxial polydactyly, while the male patients only had preaxial polydactyly. Only one patient had foot involvement. TA heterogeneous mutations was discovered in the ZRS (105C>G) in all patients, the same mutation was not detected in 2 healthy family members.
CONCLUSION
The inheritance pattern of PPD was autosomal dominant inheritance. There was a significant variability of symptoms among family patients. The heterozygous mutation of the ZRS (105C>G) probably underlie the disease.

Objective To study the value of free-style perforator flap in repairing nasal defects after tumor resection.Methods On the basis of the guidance of free-style perforator flap design concept and the foundation of vascular localization by Doppler based on the ultrasonic echo intensity,combined with nasal beauty subunits,we designed free-style perforator flap in different forms such as V-Y advancing flap,rotating flap,and propeller flap,which had with free-style perforator in pedicle all.We transplanted the flaps to repair nasal defects after tumor resection.The area of the flaps was between 2 cm x 1.0 cm and 8.0 cm x 5.0 cm,and the diameter of the perforate vessel in the pedicle of flap was between 0.3 mm-3 mm,and some of the pedicles were composed of perforate vessel tube bundle.In order to reduce recurrence rate,the radiotherapy was performed according to the pathology in 1 month after surgery.Results In 31 cases of this group,29 cases were performed and the postoperative shape was good.1 case appeared postoperative hemorrhage,and the epidermis of flap formed blister because of greater tension,and the patient healed 10 days later after extraction the bubble fluid and changing medicine.The flap of 1 case was silted because the venous was blocked,and the acupuncture was treated,and then the flap got delayed union.23 cases received adjuvant radio therapy after surgery and fellowed up from 6 months to 5 years,showing that local profile and color were satisfacfory without tumor recurrence.Conclusions It is worthy of clinical promotion to designing freetype perforator flap and to repair defect after extensive nasal tumor resection on the basis of beauty subunits in nasal and vascular anatomy,which can not only reduce the recurrence rate by postoperative radiotherapy in time,but also realize better cosmetic requirements.

Objective To study the effect of multi-point multi-axis suspension training on nonspecific low back pain (NLBP) through surface electromyography (sEMG). Methods From October, 2016 to November, 2017, 24 patients with unilateral NLBP (NLBP group) were randomly divided into dynamic group (n=12) and static group (n=12); other 12 healthy volunteers were selected as control group. NLBP group was trained on multi-point multi-axis suspension training system, the dynamic group accepted pelvic-up training in the supine position, while the static group accepted lumbar neutral keep training, for ten days. NLBP group was measured with average electromyographic values (AEMG) of affected musculi multifidi before and after treatment, and assessed with Visual Analogue Scale (VAS) of pain; while the control group was measured AEMG of unilateral musculi multifidi. Results The AEMG in static and pelvic-up positions was more in NLBP group than in the control group before treatment (t>3.209, P<0.01), and it was less when keeping neutral position (t=-2.364, P<0.05). The AEMG improved in NLBP groups after treatment (t>2.982, P<0.01). The AEMG in static position and in keeping neutral position was not significantly different among the three groups after treatment (F<2.921, P>0.05), and it was the most in the dynamic group as pelvic-up (P<0.001). The score of VAS decreased in both NLBP groups after treatment (t>10.416, P<0.001), and it was less in the static group than in the dynamic group (t=-4.389, P<0.001).Conclusion sEMG changes take place in patients with NLBP. Multi-point multi-axis suspension training is effective through improving the core muscle group, and it is more effective in static maintenance training.

Objective:
To introduce the application of free-style perforator flap based on aesthetic units to repair facial defect after tumor resection.
Methods:
By following the concept of free-style perforator flap and the principle of facial aesthetic unit, the design of a free-style perforator flap allowed over any nearby cutaneous vessel chosen purely on the characteristics of its Doppler signal. Conventional knowledge of anatomical landmarks and possible vascular variations were less relevant. A greater freedom in flap selection was gained to recover defect in different forms such as rotation flap, advanced flap and propeller flap, which were all based on free-style perforators. The flap size ranged from 1.5 cm×1.0 cm to 12.0 cm×6.0 cm with the perforator diameter of 0.3-3.0 mm in pedicle, and some of the pedicles are "perforator clusters" .
Results:
A total of 72 cases underwent surgery, and 68 cases survived completely with satisfactory appearance. 1 case healed two weeks later through dressing due to undesired healing, which result ed from high tension secondary postoperative blooding. 3 cases healed in a delay due to congestion and gained acupuncture treat.
Conclusions
The free-style perforator flap, which depended on Doppler-discerned perforator and facial aesthetic unit, represents safe, reliable and versatile for repairing facial defect after extended resection, and it not only offers a greater freedom in flap selection but also provides good aesthetic result.
