The paper presents a detailed review of British pharmaceutical standards including British Pharma-copoeia, European Pharmacopoeia, British Approved Names, Reference Standards and Non-Statutory Pharmaceutical Standards. British pharmaceutical standards are established by the British Pharmacopoeia Commission, Expert Advi-sory Groups, Panels of Experts and Working Parties, British Pharmacopoeia Commission Secretariat, British Pharma-copoeia Laboratory, and standard-setting procedures are clear and definite. British Pharmacopoeia standards are le-gally binding, and pharmaceutical products sold in the United Kingdom must comply with pharmacopoeia require-ments. British pharmaceutical standards can serve as an important reference for reforms to China’s pharmaceutical standards, including the scientific management of pharmaceutical standards, the improvement of organizational frame-works in the establishment pharmaceutical standards, the promptness of amendments to pharmacopoeia, and the uni-versality of international exchanges.

Objective: To explore the object relation in the college students with borderline personality disorder(BPD) by thematic appearance test (TAT). Methods: The result of the social cognitive and object relation scale (SCORS) of BPD students was compared with that of the non-BPD students. Results: The BPD students got significantly lower scores in complexity of representations of people, affect-tone of relationship paradigms, and understanding of social causality. But there was no significant difference in the capacity for emotional investment in relationships and moral standards. Conclusion: The object relation of BPD students is different from that of the non-BPD students. The non-BPD students develop better in complexity of representations of people, affect -tone of relationship paradigms, and understanding of social causality.

Objective To investigate the pre-emptive analgesia effects of hydromorphone on stress reaction in patients undergoing gynecological laparoscopic surgery.Methods Forty ASA Ⅰ or Ⅱ patients [age:45-58 years,body mass index:18-24 kg· (m2)-1] undergoing gynecological laparoscopic surgery were randomly divided into 2 groups (n =20 for each group):treatment group and control group.Hydromorphone (1 mg) was intravenously injected before anesthesia in treatment group.In the two groups,after routine induction and incubation,remifentanil (0.2 μg· min-1 · kg-1) and propofol (0.1 mg· min-1· kg-1) were injected with micro perfusion pump,cisatracurium was injected intermittently.Injection of remifentanil and propofol was stopped when skin suture started.The concentrations of epinephrine(E) and norepinephrine(NE) were obtained before induction (t1),pneumoperitoneum (t2),1 h after pneumoperitoneum (t3) and extubation (t4),respectively.The heart rate,blood pressure and the time of operation to extubation of the patients were recorded.Results There were no significant changes in extubation time after operation among the groups.Heart rate and systolic blood pressure were significantly lower in the treatment group than in the control group (P ＜ 0.05).Plasma E and NE levels at t1 were significantly lower than those at t2,t3 and t4.Plasma E and NE were significantly lower in treatment group than that of control group at t2,t3 and t4 (P ＜ 0.05).Conclusion Pre-emptive analgesia of hydromorphone can significantly decrease the release of epinephrine and norepinephrine during and after laparoscopic surgery,restrain the increase of heart rate and systolic blood pressure during extubation,without influence of revival time.

Store-operated Ca(2+) channels (SOCs) are plasma membrane Ca(2+) permeable channels activated by depletion of intracellular Ca(2+) store. Ca(2+) entry through SOCs is known as store-operated Ca(2+) entry (SOCE), which plays an important role in the functional regulation of airway smooth muscle cells (ASMCs). Protein kinase C (PKC) has been shown to have an activating or inhibiting effect on SOCE, depending on cell types and PKC isoforms that are involved. In ASMCs, the effect of PKC on SOCE has not been elucidated so far. In this study, the role of PKC in the activation of SOCE in rat ASMCs was examined by using Ca(2+) fluorescence imaging technique. The results showed that acute application of PKC activators PMA and PDBu did not affect SOCE induced by the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) inhibitor thapsigargin. The non-selective PKC inhibitor chelerythrine significantly inhibited thapsigargin- and bradykinin-induced SOCE. RT-PCR assay identified PKCα, δ and ɛ isoforms in rat ASMCs. PKCα-selective inhibitor Gö6976 and PKCɛ-inhibiting peptide Epsilon-V1-2 had no effect on SOCE; by contrast, PKCδ-selective inhibitor rottlerin attenuated SOCE dramatically, suggesting that PKCδ was the major PKC isoform involved in the activation of SOCE in ASMCs. Moreover, PKC down-regulation by extended exposure to high doses of PMA or PDBu also reduced SOCE, confirming the essential role of PKC in the activation of SOCE in ASMCs. In addition, PKC down-regulation did not influence the expression of stromal interaction molecule 1 (STIM1) and Orai1, two elementary molecules in the regulation and activation of SOCs. These results identified PKCδ as an essential PKC isoform involved in the activation of SOCE, and confirmed that PKC regulates the function of ASMCs in a SOCE-dependent manner.

AIM:To investigate the effects of down-regulation of protein kinase C (PKC) on the activity of storeoperated Ca2 + channels (SOC) and the proliferation of airway smooth muscle cells (ASMCs). METHODS:Rat bronchial smooth muscle cells were isolated and cultured. Fluo-3 /AM fluorescence was measured by laser confocal microscope to assessing intracellular Ca2 +. Downregulation of PKC activity was achieved by incubation of ASMCs with PKC activator phorbol-12-myristate-13-acetate (PMA,10 ?mol/L) or phorbol 12,13 -dibutyrate (PDBu,1 ?mol/L) for 24 h. The proliferation of ASMCs was assayed by calculating the reduction rates of Alamar blue. RESULTS:Down-regulation of PKC activity by longterm exposure of PMA or PDBu inhibited the proliferation of ASMCs,the similar results were obtained by using PKC inhibitor chelerythrine. Both downregulation of PKC activity and inhibition of PKC activity by chelerythrine reduced Ca2 + entry through SOC channels. Low concentration of PMA (0. 1 ?mol/L) promoted the proliferation of ASMCs,and this effect was inhibited by SOC blocker SKF-96365. CONCLUSION:Inhibition or down -regu-lation of PKC activity results in the inhibition of SOC channels,suggesting that PKC is involved in the activation of these channels. Ca2 + entry through SOC channels might contribute to PKC-promoted proliferation of ASMCs.

OBJECTIVEThis study aimed to evaluate the effort of applying frontal and occipital bones in extensive cranioplasty and preserving multiple cranial bone flaps adhered to the dura mater in the treatment of sagittal synostosis.

METHODSFrom April 2008 to June 2013, sixty-three children with sagittal synostosis, aged 5 months to 3 years, were included in the study. The frontal bone flap was removed using an air drill. The occipital and bilateral temporal bone flaps were cut open but not detached from the dura mater or fixed to produce floating bone flaps. The skull bone was cut into palisade-like structures. Brain compression from both sides and the base of the skull was released and the brain expanded bilaterally through the enlarged space. Only a long strip-shaped bone bridge remained in the central parietal bone. Subsequently, the frontal bone flaps and occipital bone flap were pushed towards the midline and fixed with the parietal bone bridge to shorten the anteroposterior diameter of the cranial cavity and allow the brain to expand bilaterally to correct scaphocephaly. The CT images showed that both sides of the parietal bone of artificial sagittal groove gradually merged postoperative 1 year, and skull almost completely normal healing after operation 2 or 3 years, without deformity recurrence within 5 years. Among them all, 61 children's intelligence is normal and 2 children's lagged behind normal level, no further improvement.

RESULTSPatients were followed up 1 - 5 years (an average of 43 months). Skull growth was excellent in all patients, the anteroposterior diameter was shortened by 14.6 mm averagely, the transverse diameter was increased by 12.3 mm averagely, the prominent forehead was corrected, and scaphocephaly improved significantly. There were no complications such as death and skull necrosis.

CONCLUSIONSThe application of frontal and occipital bones in extensive cranioplasty and preserving multiple cranial bone flaps adhered to the dura mater can be used in the treatment of sagittal synostosis. Surgery without removing bone flaps is less traumatic and results in no massive bleeding. It can effectively relieve brain compression and promotes transversal expansion of the brain during surgery and subsequent normal brain development.

Objective To compare the diagnostic efficacies of narrow-band imaging (NBI) in distinguishing neoplastic from non-neoplastic colorectal lesions with routine endoscopy and with magnifying endoscopy. Methods Patients with colorectal lesions detected by NBI from September 2008 to February 2010 were enrolled in the study. These lesions were classified by pit pattern and capillary pattern, which was then assessed by reference to histopathology. Results A total of 100 patients with colorectal lesions were enrolled, and the lesions were observed by NBI with ordinary endoscopy (n =64) and NBI with magnifying endoscopy (n =36), respectively, and 7 cases (5 in NBI with ordinary endoscopy and 2 in NBI with magnifying endoscopy) which did not meet the diagnostic criteria were excluded. The overall diagnostic accuracy of NBI endoscopy in distinguishing neoplastic from non-neoplastic colorectal lesions was 91.4% ( 85/93 ), in which NBI with ordinary endoscopy and magnifying endoscopy was 89. 8% (53/59) and 94. 1% (32/34),respectively, with both significantly higher than that of conventional colonoscopy reported in the literature (79. 1% ) (P ＜ 0. 05 ). However, no significant difference was detected between 2 methods ( P ＞ 0. 05 ).Conclusion Similar with NBI magnifying endoscopy, NBI endoscopy without high magnification may also be useful to distinguish neoplastic from non-neoplastic colorectal lesions.

Aim Paclitaxel(PTX)has shown an effect against human cancer. However, serious drawbacks hamper PTX clinical use.Overcoming paclitaxel limi-tations is one of the best approaches to enhance water solubility.Methods In this study,water-soluble pa-clitaxel prodrug was prepared,folic acid-polyethylene glycol-glutamic-paclitaxel (FA-PEG-Glu-PTX ) com-posed of folic acid (FA,target),amino acids (Glu, linker),and polyethylene glycol(PEG)in order to im-prove the solubilization and stability. The chemical structure and physicochemical property of prodrug were measured by LC-MS,solubility,drug release rate to e-valuate the antitumor activity and cytotoxicity of FA-PEG-Glu-PTX.MTT assays were conducted on MDA-MB-231,MCF-7,A549 and HELF cell lines.FA-PEG-Glu-PTX prodrugs were labeled with 5 amino flu-orescence visible fluorescent dye (5 AF ) for fluores-cence microscopy.Results The successful conjugation of FA-PEG-Glu-PTX was confirmed by LC-MS,and had better water solubility,release rate curve.In vitro studies indicated that foliate receptor(FR-α)mediated uptake of PTX-conjugated multi-small molecules carri-ers induced highly targeting ability,and antitumor ac-tivity,as well as reduced side toxicity effects of PTX. Conclusion FA-PEG-Glu-PTX has a good antitumor activity.

Objective To investigate the expression of Fascin in early-stage NSCLC, evaluate the relevance between Fascin expression level and prognosis.Methods The immunohistochemistry method was used to assess the expression of Fas-cin in 111 lung cancer FFPE tissues with stage Ⅰ and Ⅱ NSCLC.The relationship between Fascin expression and the clinico-pathological characteristics was analyzed.The prognostic significance of Fascin expression was evaluated with Kaplan-Meier sur-vival analysis.Results In the early-stage of NSCLC, the positive rate of Fascin expression was 64.8%, no expression in the paracarcinoma tissue.The positive rate of squamous cell carcinoma was 78.7% and was significantly higher than that in adeno-carcinoma 48.0%(P<0.01).Whether in squamous cell carcinoma or adenocarcinoma group, the expression of Fascin was correlated significantly with lymph node metastasis tumor stages and DFS(P<0.05).And the positive expression of Fascin was an independent risk factor of poor prognosis for patient with NSCLC .Conclusion Fascin is expected to be a biomarker for the prognosis of patients with early-stage NSCLC.
