Professor YANG Zhao-min inherited the ancient doctors'experiences about point-prescription with the principle of 'inheriting the ancients without being formalistic in the ancients,bringing new ideas without losing contact with fountainhead of TCM'. He explored new ideas based on the ancient therapy,and summed his distinctive experience up as two types:simple recipe of acupuncture and moxibustion (single point,double points,three points) and compound recipe of acupuncture and moxibustion (more than fi ve points).Those were simple-clear-essential-new in composition and form,and effective therapy in clinic.

[Objective]To explore the clinical efficiency,operative methods,apparatus assembly and postoperative administration of Ilizarov technique in the correction of talipes equinovarus.[Method]From January 2003 to May 2006,32 patients were corrected with QIN Si-he's orthotics devices on the Ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.Among these patients,2 were caused by peroneal nerve injury,l by tumor in the vertebral canal,5 by meningocele,11 were caused by poliomyelitis,13 by congenital talipes equino-varus.In accordance with deformities,external fixator and limitied operative methods were dertermined.The limited release of soft tissue were performed in 7 patients,limited osteotomy in 25 patients.The dynamic muscle balance operation were performed in 9 patients with imbalance of muscle strength.According to the Ilizarov technique,the fixative rods were installed.The telescopic rods on the apparatus were rotated one week after the operation,the divices had corrective function in three-dimensional directions.The deformity of talipes equinovarus,internal rotation and drooping of the forefoot were gradually corrected,and the patients could bear weight and walked on the deformed foot.The mean duration of traction were 42 days,then removed the external fixator maintained with plaster for a site time.[Result]All patients were followed up from 12 months to 37 months with an average of 17 months.There was no recurrence of the deformity and feet function was good while walking on full weight-bearing.None of the complication occurred postoperatively sush as infection in the incision,neurovascular injury and ankle dislocation.[Conclusion]With Ilizarov technique to correct talipes equinovarus is a safe,minimally invasive and effective method.Combined with limited operation Ilizarov technique can correct severe talipes equinovarus which is unattainable by traditional orthopedic surgery,and shorten the treatment period,avoid severe complications.

This article was aimed to study effects and mechanisms of Gymnema sylvestre on protein kinase B (PKB) and its phosphorylation in adipose tissues of KKAy mice which were mainly characterized by insulin resistance (IR). A total of 18 KKAy mice were randomly divided into the diabetes model (DM) group and Gymnema sylvestre (GS) group according to body weight levels. And 9 normal C57BL/6J mice were used as the normal control (NC) group. Intragastric administration of medication was given to mice for 8 weeks. At the end of the experiment, all animals were tested for fasting plasma glucose (FPG) and fasting insulin level (Fins) for evaluation of insulin sensitivity index (ISI). Expressions of phosphoinositide-dependent kinase-1 (PDK1), PKB, P-PKB (Ser473), P-PKB (Thr 308) in adi-pose tissues of epididymis were determined. The expression of phosphatase and tensin homolog (PTEN) mRNA was also determined. The results showed that compared with the DM group, the GS group showed lower FPG and Fins, higher ISI. The expression of P-PKB (Ser473) phosphorylation and P-PKB (Thr 308) were increased, and the PDK1 and PTEN mRNA were decreased. It was concluded that GS can improve insulin sensitivity of KKAy mice through activating PKB by up-regulate the expression of P- PKB (Ser473) and its phosphorylation ratio and P- PKB (Thr 308) in adipose tissues.

ObjectiveTo evaluate the impacts of pereutaneous nephrolithotomy (PCNL) on perioperative renal hemodynamics.MethodsThe hemodynamics of operated renal arteries of 30 patients who underwent unilateral PCNL with single pole access were observed 1 day before and 5-7 days after operation with CDFI.Parameters were analyzed statistically.ResultsAfter operation,resistance index (RI) of renal arteries decreased (P＜0.05).The diastolic flow statistically increased at main renal artery (MRA) of renal hilus,interlobar renal artery and interlobular renal artery (all P＜0.05).After PCNL,in serious hydronephrosis patients,RI decreased (P＜0.05) at segmental renal artery (SRA) and interlobar artery,end-diastolic flow velocity (Vmin) increased at interlobar renal artery (P＜0.05).In moderate hydronephrosis patients,RI decreased at all renal arteries (P＜0.05) after PCNL,Vmin increased at MRA and interlobular renal artery (P＜0.05).In minor hydronephrosis patients,RI decreased at MRA and SRA,Vmin increased at SRA.In patients without hydronephrosis,RI changeed like serious hydronephrosis patients.ConclusionAfter PCNL,ipsilateral renal perfusion improves,renal diastolic flow increases and RI decreases.CDFI can be used to observe the blood perfusion of kidney,and provide quantitative information of renal hemodynamics.

AIM:To explore the differences between unilateral recess-resection (R & R) and bilateral lateral rectus recession (BLR-rec) in the treatment of basic intermittent exotropia.METHODS: A retrospective analysis of treatment of basic intermittent exotropia in 89 patients,in which 49 cases underwent unilateral recess-resection,40 cases underwent bilateral lateral rectus recession of external rectus retroperitoneal surgery January 2013 to January 2015 in our hospital.The stereopsis and strabismus were observed in 1d,1,6mo,1 and 2a after operation.RESULTS: There was no significant difference in the success rate and oblique degree between the two groups after 1d,1,6mo,1 and 2a (all P>0.05),but the success rate of the operation was reducing as time passed.After 2d of the operation,the drift of the R & R group was 12.10±5.74PD and the drift of the BLR-rec group was 7.78±4.21PD,the difference was statistically significant (P=0.021).The R & R group was more likely to cause lateral slanting than BLR-rec group.Two groups of patients with nearly stereopsis were both significantly improved,there was no significant difference between the two groups in the two groups (x2=4.530,P=0.210).CONCLUSION: The long-term stability of BLR-rec is superior to R & R.

Objective To observe the value of speckle tracking imaging(STI) in assessing early changes of left ventricular diastolic and systolic function in patients with essential hypertension (EH). Methods Sixty-five EH patients with left ventricular normal geometry (LVN) ,including 33 cases with non-left atrial enlargement(NLAE) and 32 cases with left atrial enlargement (LAE),and 45 normal persons out of them were recruited as study subjects. Peak systole (S), peak early diastole (E'), peak late diastole (A')and E'/A' ratio at longitudinal strain rate(SrL) of three segments in long-axis views and radial strain rate (SrR),circumference strain rate(SrC) and rotation rate(RotR) of three levels in short-axis views were measured. Results There were no segment differences between A' at SrL in three segments or level differences between S and A' at SrR and S at SrC in three levels in NLAE group and LAE group. Compared with controls,NLAE group and LAE group had significantly decreased S and E' at SrL and E'/A' at SrL, SrR and SrC,increased A' at SrL,SrR and SrC and E' at RotR. Conclusions It was indicated by STI that early LV dysfunction in EH was appeared on diastolic as well as systolic dysfunction.
