Objective To explore the causes,clinical characteristics and new measurements concerning with diagnosis and treatment of hypophosphatemic rickets.Methods Thirty children with hypophosphatemic rickets had been diagnosed and treated in our hospital from 1996 to 2005.Clinical data were retrospectively analyzed,including family history(the attack rates of parents and styles of inheritances),clinial characteristics(the attack ages and severity of skeletal developing malformation),serum biochemistry(plasma calcium,phosphate and alkaline phosphatase level),and X-ray in bones and treatment methods.Results All these patients presented with typical manifestations and signs of rickets.The minimum age of definitive diagnosis of hypophosphatemic rickets was 1.5 years old;the maximal age was 10 years old.All of 30 cases had failed to conventional treatment of vitamin D(VitD) deficient rickets for 6 months.Early supply of phosphate,VitD and calcium could effectively improve the outcomes of patients.Patients diagnosed and treated before 2 years old had better prognosis,while that diagnosed and treated later than 5 years old would be result in severe skeletal malformation.Conclusions It is difficult to distinguish hypophosphatemic rickets from VitD deficient rickets.It is very important that misdiagnosis of this disease usually leads to severe skeletal malformation.Early diagnosis and treatment can effectively improve the skeletal development of patients.

Objective To study the therapeutic effects of intermittent hypoxia therapy(IHT)in isolated systolic hypertension(ISH)patients with elevated cerebral blood flow velocity(Vp),and to explore the mechanisms involved.Methods Seventy-six ISH patients with increasing Vp and normal pulsatility index(PI)of the middle ce- rebral artery(MCA)were randomly divided into a therapy group and a control group.IHT was administrated in the therapy group,and air in the control group.The Vp and PI of the MCA and blood pressure(BP)were observed be- fore and after treatment.Results Vp and systolic blood pressure(SBP)were significantly reduced after IHT(P<0.01)compared with the therapy group's scores betore treatment,but PI and diastolic blood pressure showed no sig- nificant difference.There was no significant change in BP,Vp or PI in the control group before or after treatment. Conclusion IHT has therapeutic effects on ISH by reducing Vp and moderating SBP.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

This paper aimed to study the effect nitrogen supplying on biomass accumulation and root respiration dynamic change of Glycyrrhiza uralensis and reveal the metabolic pathway of root respiration impact the biomass accumulating of G. uralensis. Six groups of one-year-old G. uralensis were fertilized with total nutrition containing various nitrogen concentration (0, 0.5, 1, 2, 4, 8 mmol x L(-1)) every week. At the end of every month, from June to October, the volume respiration rate and biomass of different classes of root samples were determined, and the correlation between root respiration and biomass was analyzed. The results indicated a negative correlation between volume respiration rate and biomass, nitrogen supply significantly affected both root respiration and biomass of G. uralensis by reducing root respiration and increasing root biomass. Under 8 mmol x L(-1) nitrogen supplying, there existed the optimal inhibition of root respiration, which has increased biomass of G. uralensis.

AIM: To investigate the curative effect of phacoemulsification and intraocular lens ( IOL ) implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-closure glaucoma ( PACG) . · METHODS: Totally 80 patients with age-related cataract merging with PACG were in our hospital from January 2014 to January 2016. The preoperative average intraocular pressure ( IOP) was 33. 22 ± 3. 17mmHg; the average depth of anterior chamber was 2. 07 ± 0. 15mm;the dynamic situation of primary angle closure ≤1/2 cycle by gonioscope. They were randomly divided into Group A and B for doing a study. All the two groups were treated with phacoemulsification and intraocular lens implantation. And the Group A was with goniosynechialysis. The following up period was 2mo, and we observed the IOP, chamber depth and the anterior chamber angle. · RESULTS: The change of chamber depth and intraocular pressure about the two groups: the average intraocular pressure of the Group A was 15. 11 ± 3. 67mmHg,the chamber depth was 3. 11±0. 08mm;those of the Group B were 17. 24 ± 1. 67mmHg, 2. 76 ± 0. 15mm respectively; the differences had statistical significance (P<0. 05). Postoperatively, there were 28 eyes (70%) in Group A with fully open anterior chamber angle, and 18 eyes (45%) in Group B (P<0. 05). · CONCLUSION: The phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-dosure glaucoma is safe and reliable. It's simple to operate, and do not increase the risk of surgery.

OBJECTIVETo explore the relation between the positive rates of autoantibodies against beta(1) adrenergic receptor (beta1-receptor)and (M2-receptor) with urinary albumin excretion rate (UAER) in type 2 diabetes patients with refractory hypertension.
METHODSAutoantibodies against beta(1)- and M(2)-receptor as well as autoantibodies were determined in type 2 diabetes patients with (n = 136) or without (n = 111) refractory hypertension, hypertensive patients without renal failure (n = 60) and healthy control subjects (n = 40, control) by ELISA.
RESULTSThe positive rates of the autoantibodies against beta1-receptors (44.9%) and M(2)-receptor (37.5%) in patients with type 2 diabetes with refractory hypertension were significantly higher than those in patients with type 2 diabetes without refractory hypertension (27.9% and 24.3%, respectively, all P < 0.05), in patients with hypertension without renal failure (11.7% and 15.0%, all P < 0.01) and in healthy controls (8.3% and 7.5%, all P < 0.01). In type 2 diabetes patients with refractory hypertension and renal failure (UAER > or = 200 microg/min), the positive rates of the autoantibodies against beta(1)-receptor (87.1%, 27/31) and against M(2)-receptor (67.7%, 21/31) were significantly higher than those in type 2 diabetes patients with refractory hypertension but without renal failure (UAER 20 - 199 microg /min, 46.7%, 28/60 and 41.7%, 25/60, respectively, all P < 0.05).
CONCLUSIONThe serum beta(1)- and M (2)-receptor autoantibodies are positively associated with the UAER level and suggest that these autoantibodies against beta(1) and M(2)-receptor may play important roles in the pathogenesis of the type 2 diabetes with refractory hypertension.
