Not only calmodulin (CAM) with Ca2+ regulates the activity of many enzymes and proteins, but also free-CaM (no Ca2+bound) and Ca2+-independent CaM-binding proteins play roles in plant and animal cells. There is no in vivo method to identify the interaction between free-CaM and Ca2+-independent CaM-binding protein (CaMBP). Using site-directed mutagenesis by polymerase chain reaction (PCR), 5 mutant Arabidopsis calmodulin isoform 2 (AtCaM2) genes, mCaM21, mCoM212,mCaM2123, mCaM2124 and mCaM21234 were obtained. The mutant mCaM2 encoded glutamine in place of glutamate (E32Q; E68Q; E105Q; E141Q) in one or more EF-hand Ca2+-binding motifs of AtCaM2. The recombinant mCaM2 proteins were produced in Escherichia coli, and subsequently separated on SDS-PAGE in the presence of Ca2+ or EGTA, their electrophoresis mobilities were related with that of mutant EF-hand motifs. 45Ca2+ overlay analysis indicated that the more glutamate replaced by glutamine, the lower affinity with Ca2+ in the mCaM2 proteins. The mCaM21234 mutant protein (E32Q; E68Q; E105Q;E141Q) was unable to bind Ca2+. Using yeast two-hybrid technique with mCaM21234 as bait, it was possible to see interaction in Arabidopsis of AtCaM2 with IQD26, a calcium-independent CaM-binding protein. Site-directed mutation of AtCaM2 will aid the research of Ca2+, CaM and Ca2+-independent CaMBPs in plant biological processes.

OBJECTIVE:To determine the contents of Pb,Cd,Hg,As and Cu in Panax notoginseng,Angelica sinensis,Ligus-ticum chuanxiong,Fallopia multiflora and Rheum palmatum commercially available in Tangshan. METHODS:Microwave diges-tion-inductively coupled plasma mass spectrometry(ICP-MS)and single factor index and Nemerow comprehensive index were used to evaluate the heavy metal pollution in TCM powder samples;and the heavy metal limiting values in Green Trade Standards of Im-porting & Exporting Medical Plants & Prescriptions were used to evaluate the pollution of heavy metal samples. RESULTS:In the samples in 12 batches of 5 TCM powders,there were 2 heavy metal exceeded samples (P. notoginseng-3 and L. chuanxiong-2), the exceeded rate was 16.7%,exceeded indexes were Cd and Hg with the exceeded rates of 16.7% and 8.3%,respectively;heavy metals with Single factor index greater than 1 were Hg and Cd in P. notoginseng-3,and Cd in L. chuanxiong-2 with the composite indexes of 1.06 and 0.81,and pollution levels were slightly polluted and reaching warning level,respectively. CONCLUSIONS:Certain heavy metal pollution is found in TCM powder commercially available in Tangshan. Therefore,it is necessary to carry out more strictly control over the heavy metal content in Chinese herbal medicines.

Objective To study the techniques and outcomes of using a retrograde pedicled vascularized radius bone flap based on the 1st,2nd intercompartmental supraretinacular artery (1,2ICSRA) for scaphoid nonunion through dorsal and palmar approaches.Methods Between March 2013 and April 2015,16 patients with scaphoid nonunion were treated by surgery through palmar and dorsal approaches.There were 14 males and 2 females with an average age of 29.1 years (range,19-51 years).The location of lesion was 6 cases on the left and 10 cases on the right.5 cases were treated with plaster fixation.11 cases weren't treated after wrists injured.The preoperative time was 6-26 months,with an average of 16.5 months.The operation was completed within one incision.The bone flaps based on 1,2ICSRA were taken through dorsal approach.The broken ends of the scaphoid fracture were cleaned,and the deformity was corrected with bone grafting and internal fixation through palmar approach.Time of fracture union and wrist pain resolution was evaluated.Wrist motion and grip strength were measured and compared.The result of the latest follow-up was used as the criterion for efficacy evaluation.The wrist pain was evaluated using visual analogue scale (VAS) and the postoperative wrist function based on the modified Mayo wrist score was recorded.Results Post-operative follow up ranged from 6-19 months,with an average of 11 months.Bone union was achieved in all the cases,so the healing rate was 100％.7 cases were healed in 11 weeks.5 cases were healed in 13 weeks.3 cases were healed in 15 weeks.1 case was healed in 17 weeks.The average healing time was 12.5 weeks.The humpback deformity of Scaphoid and DISI of 7 cases were corrected.The bending of wrist could reach 60.2°±3.2°,and the elongation could reach 51.3°± 3.5°.The radial deviation of wrist could reach 13.6°±1.42°,and ulnar deviation could reach 24.4°±1.8°.The range of grip strength was 29-64 kg,with an average of 45 kg.The 16 patients returned to normal work.The pain after wrist movement of 14 cases was completely disappeared,and the VAS was 0.Two cases felt slight pain when wrist was overworked,and the VAS were 0.9 and 1.2.The wrist joint function of patients recovered well.The modified Mayo score was 69-99,with an average of 90.75.The functional results were 12 excellent,2 good,and 2 fair,and the excellent and good rate was 87.5％ (14/16).No complications such as infection,failure of screws,orthopaedic arthritis or scaphoid necrosis were found during the follow-up period.Conclusion The technique of 1,2 ICSRA pedicled bone graft and palmar bone grafting for nonunion of scaphoid can provide convenience for us to deal with the broken ends of the scaphoid fracture,correct the malformation and graft bone through dorsal and palmar approaches.This method can protect the blood supply of the scaphoid,and promote scaphoid union.

Objective:To investigate the effect of interfering S-phase kinase associated protein 1 (SKP1) gene on apoptosis in Parkinson's disease(PD) cell model induced by 1-methyl-4-phenyl-pyridine ion (MPP+ ) and the mechanism of ubiquitin proteasome system degradation of α-synuclein (α-syn) influence.Methods:SH-SY5Y cells were divided into control group, MPP+ group, SKP1 interference group, and SKP1 interference+ MG132(UPS inhibitor) group.The cells in the control group were cultured normally. The cells in the latter three groups were incubated with MPP+ (0.5 mmol/L) for 24 h as PD model cells.The cells in SKP1 interference group were transfected with lentivirus SKP1-siRNA, and the cells in SKP1 interference+ MG132 group were transfected with lentivirus SKP1 siRNA and added with MG132 (0.5 μmol/L) for 24 h. The protein levels and mRNA levels of SKP1, microtubule-associated protein light chain 3 (LC3), lysosome-associated membrane protein (LAMP), α-syn, ubiquitin activating enzyme E1 (UBE1), parkin, and p27 in cells were detected by Western blot and RT-PCR.Flow cytometry was used to detect cell apoptosis and cycle level, and CCK-8 method was used to detect cell proliferation level.Co-immunoprecipitation method was used to explore the interaction between SKP1 and p27. SPSS 23.0 software was used for statistical analysis. One-way ANOVA was used for comparison among groups, and LSD test was used for further pairwise comparison.Results:RT-PCR and Western blot results showed that the mRNA levels and protein levels of autophagy related proteins and ubiquitin related proteins LC3, LAMP2, α-syn, UBE1, parkin and p27 in the four groups were statistically significant(mRNA: F=99.155, 43.028, 138.464, 28.200, 22.009, 28.147, all P<0.05; F=245.517, 157.634, 315.920, 2 336.472, 477.429, 2 350.201, all P<0.05). The mRNA and protein levels of LC3, Lamp2, α-syn and p27 in SKP1 interference group were lower than those in MPP+ group (all P<0.05), while the mRNA and protein levels of UBE1 and parkin were higher than those in MPP+ group (all P<0.05). The mRNA and protein levels of LC3, α-syn and p27 in SKP1 interference+ MG132 group were higher than those in SKP1 interference group (all P<0.05), and the mRNA and protein levels of UBE1 and parkin were lower than those in SKP1 interference group (all P<0.05). The results of flow cytometry and CCK-8 method showed that the apoptosis rate and cell inhibition rate among the four groups were significantly different( F=2 749.420, 171.508, both P<0.05). The apoptosis rate of SKP1 interference group was lower than that of MPP+ group ((8.22±0.25)%, (15.30±0.21)%, P<0.05), while the cell inhibition rate of SKP1 interference group was lower than that of MPP+ group((26.31±3.73)%, (55.05±3.84)%, P<0.05). The apoptosis rate of SKP1 interference+ MG132 group ((9.49±0.07)%) was higher than that of SKP1 interference group, and the cell inhibition rate ((36.06±2.85)%) was higher than that of SKP1 interference group (both P<0.05). The results of immunoprecipitation method showed that P27 decreased after SKP1 immunoprecipitation. Conclusion:After SKP1 gene was interfered, the autophagy function of PD cells decreased, which may be related to parkin promoting α-syn ubiquitination, activating UBE1/ Parkin-mediated UPS pathway to degrade α-syn, and mediating P27 to inhibit apoptosis.
