The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

It is known that extracorporeal shock wave (SW) may promote healing of fracture. A previous study reported that SW promoted human bone marrow stromal cells (hMSCs) towards osteoblasts in vitro. To study the osteogenesis ability of hMSCs treated by shock wave in porous hydroxyapatite (HA) in vivo, primary hMSCs of SW group and control group were cultured in the porous HA for 2 weeks and then implanted into subcutaneous sites of nude mouse. These implants were harvested and prepared for the biochemical analysis of alkaline phosphatase activity by AKP kit, histological analysis of decalcified and undecalcified sections and morphology by scan electric microscope (SEM), as well as osteocalcin mRNA expression by RT- PCR 4 weeks and 8 weeks after implantation. It showed that cells of SW and control group almost covered the rough surface of HA before implantation and the extracelluar matrix of SW group was abundant by SEM photomicrograph . The histological analysis and SEM photomicrograph showed active bone formation 4 weeks and 8 weeks after implantation, as well as tetracycline labeling under fluoroscopy analysis in SW group. Alkaline phosphatase in supernatants of the implants detected 4 weeks and 8 weeks after implantation in SW group was higher than in control group (P
4.Study on the validity of the Symptom Check-List-90 of Chinese version
Journal of Third Military Medical University 2001;23(4):481-483
Objective To investigate the validity of the Chinese version of the Symptom Check-List-90 (the SCL-90) in Chinese population. Methods A total of 624 normal person and 268 out patients were examined with the SCL-90. Results (1)The internal consistency of the original subscales was found to be good and Cronbach's coefficient alpha ranged from 0.78 to 0.90; (2)Discrimination function analysis based on the 9 original subscales showed that the power of the SCL-90 in discriminating the patients and the community was good with a corrective rate of 80.6%; (3)Factor analysis on the items of the questionnaire yielded a very strong un-rotated first factor which could represent other factors; (4)High inter-correlations were found between the 9 original subscales of the SCL-90 with a correlation coefficient ranging from 0.39 to 0.79. Conclusion (1) The SCL-90 is acceptable as a research setting and psychiatric screening inventory; (2) The SCL-90 does not have potential as an inventory to distinguish different diagnostic groups; (3) The SCL-90 is not a multidimensional inventory.

OBJECTIVE:
To study the expressions of focal adhesion kinase (FAK) and phospho-FAK( p-FAK) during skin incised wound healing and the applicability of time-dependent expressions of FAK and p-FAK.
METHODS:
The expression of FAK and p-FAK in cutaneous incised wound in mouse were investigated by immunohistochmeistry and Western blotting.
RESULTS:
FAK and p-FAK expression were detected in polymorphonuclear cells (PMNs) in the wound and adjacent regions 3 hours post-injury. The expressions of FAK and p-FAK were detected in a large number of infiltrating PMNs and some of mononuclear cells (MNCs) from 6 to 24 hours after injury. The MNCs and fibroblastic cells (FBCs) accounted for most part of the FAK and p-FAK positive cells from 3 to 14 days after injury. The numbers of FAK-positive cells increased continuously, reaching a peak at post-injury day 3, and then started to decrease from post-injury day 5 to 14. The changes of p-FAK-positive cells were similar to that of the FAKs, and reached a peak at 12 hours after injury.
CONCLUSION
Both FAK and p-FAK displayed a time-dependent expression during skin incised wound healing in mouse, with p-FAK being superior to FAK. Both FAK and p-FAK may potentially be used as new markers for determination of the wound interval.

OBJECTIVETo investigate the clinical application of free superficial iliac circumflex artery skin flaps, as well as the management of donor site defects.
METHODS17 free superficial iliac circumflex artery skin flaps were applied for the traumatic defects or deformities on face, neck, foot, hand, ankle and lower leg, respectively. The donor site defects were closed directly or covered by paraumbilical island flaps.
RESULTSThe 17 flap size ranged from 5 cm x 3 cm to 19 cm x 14 cm. 16 flaps survived completely except 1 flap with partial necrosis, which was closed by free skin graft. The donor site defects were closed directly in 10 cases, and covered by paraumbilical island flaps in 7 flaps without no flap necrosis. The abdomen had a good appearance.
CONCLUSIONSGood appearance can be achieved with free superficial iliac circumflex artery skin flaps for the defects on face, neck, foot, hand, ankle and lower leg. Paraumbilical island flap can be used for the donor site defects.

Objective To compare and quantify the determinants in quantitative electroencephalogram(q-EEG) and heart rate variability power spectrum analysis(HRV-PSA) of ketamme(KTM) anesthesia for preschoolers. Methods Seventy four cases were selected and assigned into 3 groups named A(4-5 years), B(5-6 years), C(6-7 years), 22,28,24 cases in every group respectively. All cases were induced with KTM 5 mg /kg intramuscularly and changes of determinants were recorded continuously. If body movement happened, KTM would be injected with 1 mg/kg. Results On pre- anesthesia, BIS in group A was the least among 3 groups, while LF/HF and HRVI were the largest(P
9.Discussing tuina for atlantoaxial subluxation in adults based on the theory of 'tendon-bone balance'

According to Chinese medicine, the atlantoaxial joint is a composite joint composed of tendons and bones, and the stability of the joint depends on the 'tendon-bone balance' involving tendons, ligaments, atlas and axis. Multiple causes of 'tendon off-position, joint subluxation' will lead to joint 'tendon-bone imbalance', which will evolve into atlantoaxial subluxation (AAS), endangering human health. Chinese therapeutic massage (tuina) is a very effective treatment for AAS in adults, but conventional manipulations are prone to ineffectiveness or accidents due to neglect of the causal relationship of the 'tendon-bone imbalance' and inappropriate manipulations. Compared with conventional manipulations, the rational choice of modified manipulations under the guidance of 'tendon-bone balance' theory is more effective and less risky, and more worthy of clinical promotion. From the 'tendon-bone balance' theory, we considered the shortcomings of conventional manipulations, and introduced several modified manipulations that have their own strengths in 'tendon smoothing' and 'bone setting', in order to provide new ideas for treatment of AAS in adults.
