OBJECTIVE:To observe clinical efficacy and safety of lanthanum carbonate in the treatment of hyperphosphatemia in uremic patients underwent maintenance hemodialysis. METHODS:A total of 142 uremic patients with hyperphosphatemia under-went maintenance hemodialysis were selected from Xinqiao Hospital of Third Military Medical University and Chongqing Banan District Hospital of TCM during Jan. 2012-Dec. 2016. They were given Lanthanum carbonate chewable tablets with initial dose of 250 mg,tid,when serum phosphate level ranged 1.78-2.26 mmol/L or with initial dose of 500 mg,tid,when serum phosphate lev-el was >2.26 mmol/L. Drug dosage was adjusted according the level of serum phosphate during treatment. After 1,2,3 months of treatment,the levels of serum phosphate,serum calcium,albumin,parathyroid hormone(PTH)and alkaline phosphatase were de-tected and the corrected product of serum calcium and calcium phosphorus was calculated. The occurrence of ADR was observed. RESULTS:After 1,2,3 months of treatment,the levels of serum phosphate and the product of serum calcium and calcium phos-phorus were all decreased significantly compared to before trreatment,with statistical significance (P<0.05). After 3 months of treatment,the level of corrected serum calcium was decreased significantly compared to before treatment,with statistical signifi-cance(P<0.05). There was no statistical significance in the levels of plasma albumin,calcium phosphorus or PTH before and af-ter treatment (P>0.05). Total response rate was 93.7%. There were 19 cases of patients with mild adverse reactions. CONCLU-SIONS:Lanthanum carbonate in the treatment of hyperphosphatemia in uremic patients underwent maintenance hemodialysis shows good clinical response rate,can significantly reduce the levels of serum phosphate and the product of serum calcium and calcium phosphorus with good safety.

OBJECTIVEMedicinal properties are the basic attribute of traditional Chinese medicines (TCM), while the medicinal property theory is the core theoretical foundation of TCM formula combination. In this particle, authors studied the characteristics of pharmacological effects of property combination of traditional Chinese medicines distributing along meridians, with the aim to introduce the medicinal property combination regularity into the design and optimization process of compound TCMs, and bring the medicinal property theory into full play in guiding the formula combination.

METHODIn this paper, TCMs distributing along "the lung meridian" was taken for example. The medicinal property combinations of TCMs distributing along "the lung meridian" recorded in Pharmacopeia (2010) was collected and processed. Besides, Chinese journal full-text database (CNKI) was used to collect all of pharmacological study literatures concerning the above TCMs that have been published since 1980. The pharmacological information was also supplemented by reference to Science of Chinese Materia Medica and Clinical Science of Chinese Materia Medica.

RESULTTCMs distributing along the lung meridian with different properties and tastes showed significant differences in pharmacological effects. For example, mild-sweet-lung medicines could lower blood sugar levels, decrease anoxia and enhance immunity; Mild-bitter-lung medicines showed anti-bacterial, anti-hypertension, anti-oxidation effects; Hot-sweet-lung medicines showed antibechic and anti-bacterial effects. And Hot-bitter-lung medicines showed phlegm eliminating and anti-inflammatory effects. Meanwhile, TCMs distributing along the lung meridian had similar pharmacological characteristics, such as anti-bacterial and anti-inflammatory effects, which is consistent with lung's feature in susceptibility to exogenous pathogenic factors.

CONCLUSIONIn this study, authors discovered pharmacological characteristics of different TCMs distributing along the lung meridian, which links TCM theory with modern study achievements and lays a foundation for establishing a TCM property formula combination system.

Studies on the prescription combination regularity based on medicinal tastes focus on the internal relations between the structure and hierarchy of the prescription combination system. In this paper, with the systematic and scientific self-similarity theory as the core ideology, authors systematically interpreted the self-similarity theory of medicinal properties, defined the self-similarity of prescriptions with identical or similar medicinal properties, and built the systematic view of medicinal property theory based on the prescription combination based on the entity grammar system. As a result, the system was conducive to integrating traditional Chinese medicinal knowledge of syndromes, therapeutic principles, efficacies, medicinal properties and tastes and achieving the automatic design and optimization process from symptoms to prescriptions, and providing scientific and feasible methods and technical systems for the application of the medicinal property theory, with a guiding significance to the technology, methodology and theory of decoction pieces compatibility, component compatibility and compound medicine design.

Objective To explore the impact of medication self-management module on treatment compli-ance and social function of patients with schizophrenia. Methods 66 inpatients with schizophrenia in their non-acute stage were randomly divided into training group(n=33) and control group(n=33). Both groups received the anti-psychotics therapy. Medication self-management module was only given to the training group for 8 weeks.All subjects were follow up for 6 months and were evaluated with self-made drug treatment compliance rating scale,self-made work ability rating scale, social disability screening schedule(SDSS). Results Treatment compliance,the total scores of SDSS of training group were significantly higher than that of control group after 8 weeks and 6 months: treatment compliance (χ~2=9.188,29.630, P < 0.01); the total scores of SDSS ((2.63±2.74) vs (5.27 ±3.05), (1.69±2.35) vs (4.91±3.06), P=0.000); work ability of training group was significantly higher than that of control group after 6 months (χ~2=19.443, P=0.000). Treatment compliance (χ~2=8.053, P=0. 018), the total scores of SDSS((2.63±2.74) vs (6.81±3.06), P=0.000) of training group after 8 week and 6 months were significantly higher than that of pretraining. Treatment compliance and work ability of both groups on 6 months follow up were significantly lower than that of 8 weeks (P < 0.01). Correlation analysis can-firmed that there was positive relation between the total scores of SDSS and treatment compliance, work ability on 6 months later. Conclusion Medication self-management module could significantly improve treatment compliance,social function and work ability of patients with schizophrenia.

Objective To evaluate the feeding effect of semi-demand feeding and abdominal massage on the feeding process, feeding performances and clinical safety (including the time of returning to birth weight, feeding tolerance, apnea). Methods A total of 120 preterm infants that met inclusion criteria of the study were randomly assigned to three groups, and each group had 40 cases. Control group:received standard feeding care. Semi-demand feeding group: received 5-10 minutes of oral motor intervention every time before feeding(including oral stimulation and non nutritional sucking), then decided feeding methods according to its consciousness behavior state. Semi-demand feeding combined abdominal massage group: received both semi-demand feeding and abdominal massage before feeding. Observed and recorded the three groups′ transition time, whether there were statistically significant differences in feeding performance and clinical safety. Results The feeding transition time was (11.55± 4.69), (10.98±3.85), (8.50±3.87)d in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences (F=6.088, P=0.003). In terms of feeding performance, the feeding efficiency were (7.27 ± 2.65), (9.74 ± 2.63), (9.52 ± 2.13) ml/min, the feeding proficiency were (66.31 ± 14.51)%, (76.64 ± 12.46)%, (82.26 ± 10.65)%, the volume transfer were (63.99 ± 11.02)%, (80.16 ± 14.41)%, (84.97 ± 11.16)% in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences (F=12.189, 16.383, 31.959, all P < 0.01).Among the clinical safety, the time of restoration of birth weight were (10.55 ± 1.99), (9.28 ± 1.77), (10.05 ± 2.46) d in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences(F=3.759, P=0.026). The incidence of feeding intolerance were 50.0%(20/40), 40.0%(16/40), 22.5%(9/40), and there were significant differences(χ2=6.613, P=0.037). The incidence of apnea were 37.5%(15/40), 20.0%(8/40), 15.0%(6/40), and there were significant differences(χ2=6.093, P=0.048). Conclusions The combined intervention methods could accelerate the feeding process, improve feeding performance as well as reduce the incidence of feeding intolerance and apnea. Hence, semi-demand feeding combined abdominal massage is a recommended choice for clinical use.

Objective To screen out the PI3K/Akt pathway related genes in vascular smooth muscle cells (VSMCs) subjected to cyclic strain. Method VSMCs of rat aorta were subjected to cyclic strain (10 %, 1 Hz) by using a FX-4000T system. Phosphorylation of Akt was examined by Western blotting. Suppression subtractive hybridization (SSH) method was employed to analyze the differently expressed cDNA sequence between the strained VSMCs pretreated with and without wortmannin, a specific inhibitor of PI3K. These fragments were ligated with T vectors, screened through the blue-white screening system to establish cDNA library, and was sequenced and analyzed in GenBank with BLASTN search.Result Level of Akt phosphorylation of VSMCs was significantly enhanced by the mechanical strain compared with the control. Ten different expressed sequence tags (EST) were gained after sequencing 30 clones randomly selected from 54 white clones. There may be six genes related with the mechanical strain and cell signal PI3K/Akt, such as High mobility group box 1 (HMGB1), Neural precursor cells expressed (Nedd4a), Cyclin-dependent kinase 5 (CDK5), Histone deacetylase 3 (HDAC3), Ubiquitin-like 1 (Uble1a) and Heterogeneous nuclear ribonucleoprotein H1 (hnRNP). Conclusion SSH is an effective and reliable approach to screen out the genes related with the mechanical strain and PI3K/Akt pathway in VSMCs.

AIM: To investigate the efficacy, safety and localization of multilayer amniotic membrane transplantation (AMT) for the management of corneal perforation associated with ulceration.METHODS: Six eyes (6 patients) were treated with multilayer AMT for corneal perforation associated with ulceration. The perforation size was 0.5-2mm in diameter. The amniotic membrane (AM) was applied to tamp the perforation, fill the ulcer and cover the surface of ulcer. The follow-up ranged from 5-19 months.RESULTS: The anterior chamber reformed at the first postoperative day in all patients, and kept in normal depth in the follow- up time. The epithelialization of the AM grafts was observed in about 3 weeks after surgery. During the first postoperative month, the corneal thickness at the perforation site gradually increased, and the stromal inflammatory cell invasions surrounding the corneal ulcer were gradually subsided.Two months postoperatively, the ulcer healed with scar with part neovascutarization; the corneal thickness of the ulcer area was stable and recovered almost normal. The vision was not improved in all patients after operation. During-follow up,no severe complications or recurrence of ulceration was noted.CONCLUSION: Multilayer AMT is an effective and safe method for the management of small corneal perforation associated with ulceration, but the ulcer healed with scar.
