OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.
METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.
RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.
CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

The aim of this study was to observe and compare the endogenous circadian rhythm and photoresponse of Clock gene transcription in the suprachiasmatic nucleus (SCN) and pineal gland (PG) of rats. With free access to food and water in special darkrooms, Sprague-Dawley rats were housed under the light regime of constant darkness (DD) for 8 weeks (n=36) or 12 hour-light: 12 hour-dark cycle (LD) for 4 weeks (n=36), respectively. Then, their SCN and PG were dissected out every 4 h in a circadian day, 6 rats at each time (n=6). All animal treatments and sampling during the dark phases were conducted under red dim light (<0.1 lux). The total RNA was extracted from each sample and the semi-quantitative RT-PCR was used to determine the temporal mRNA changes of Clock gene in the SCN and PG at different circadian times (CT) or zeitgeber times (ZT). The grayness ratio of Clock/H3.3 bands was served as the relative estimation of Clock gene expression. The experimental data were analyzed by the Cosine method and the Clock Lab software to fit original results measured at 6 time points and to simulate a circadian rhythmic curve which was then examined for statistical difference by the amplitude F test. The main results are as follows: (1) The mRNA levels of Clock gene in the SCN under DD regime displayed the circadian oscillation (P<0.05). The endogenous rhythmic profiles of Clock gene transcription in the PG were similar to those in the SCN (P>0.05) throughout the day with the peak at the subjective night (CT15 in the SCN or CT18 in the PG) and the trough during the subjective day (CT3 in the SCN or CT6 in the PG). (2) Clock gene transcription in the SCN under LD cycle also showed the circadian oscillation (P<0.05), and the rhythmic profile was anti-phasic to that under DD condition (P<0.05). The amplitude and the mRNA level at the peak of Clock gene transcription in the SCN under LD were significantly increased compared with that under DD (P<0.05), while the value of corresponding rhythmic parameters in the PG under LD were remarkably decreased (P<0.05). (3) Under LD cycle, the circadian profiles of Clock gene transcription induced by light in the PG were quite different from those in the SCN (P<0.05). Their Clock transcription rhythms were anti-phasic, i.e., showing peaks at the light phase ZT10 in the SCN or at the dark time ZT17 in the PG and troughs during the dark time ZT22 in the SCN or during the light phase ZT5 in the PG. The findings of the present study indicate a synchronous endogenous nature of the Clock gene circadian transcriptions in the SCN and PG, and different roles of light regime in modulating the circadian transcriptions of Clock gene in these two central nuclei.

AIMTo investigate the effect of nanoparticles for antisense oligodeoxynucleotide (ASODN) of hTERT mRNA on A549 cells.
METHODSThe cationic polybutylcyanoacrylate nanoparticles (NPs) were prepared by an emulsion polymerization process in the presence of DEAE-dextran. Antisense oligodeoxynucleotides were loaded on the particles by adsorption. The cytotoxicity of NPs and proliferation of A549 cells were detected by MTT assay. Intracellular fluorescence intensity after transfecting the 5'-FITC-labelled ASODN (FASODN) and cell cycles were determined by flow cytometry (FCM). Inverse microscope was used to observe the modality of A549 cell transfected by NPs for ASODN. The protein expression of hTERT was measured by immunocytochemistry.
RESULTSThe cytotoxicity increased evidently with the increasing concentration of NPs over 2.5 g x L(-1). The intracellular fluorescence in FASODN-NP group was obviously stronger than that in FASODN group (NPs free) after transfection for 24 h (P < 0.01). The inhibitory rate for cell modality change and proliferation after the treatment with ASODN-NP at 72 h reached peak , 62.4% , 44.6% and 36.4% for ASODN1-NP group, ASODN2-NP group and ASODN3-NP group, respectively; The cell cycle in ASODN-NP group varied observably compared with control group and sense oligodeoxynucleotide-nanoparticle (SODN-NP) group and the cell cycle was blocked in G1 phase, the cell number in S phase decreased obviously (P < 0.01); The hTERT protein expression of ASODN-NP group reduced clearly.
CONCLUSIONASODN-NP of hTERT can inhibit the proliferation of A549 cells effectively and cause the change of cell cycle, restraint of protein expression of hTERT and cell viability.

OBJECTIVETo analysis the changes of two chemical constituents, namely 2, 3-dihydro-3, 5- dihydroxy-6-methyl-4H-pyran-4-one (DDMP) and 5-hydryoxymethyl-furfural (5-HMF) produced in Radix Polygoni Multiflori after processing, with processing time, and to determine the contents of 5-HMF in samples of Radix Polygoni Multiflori and Radix Polygoni Multiflori preparata.
METHODAn HPLC method was applied with a Zobax SB-C18 (3.9 mm x 150 mm, 5 microm) column by a elution using methanol-water (10: 90) as the mobile phase. The detection was set at UV 280 nm.
RESULTThe contents of DDMP were increasing with the processing time until 24 hour, followed by a decrease until 60 hour process. The contents of 5-HMF were increasing gradually throughout the 60 hour steaming process. The contents of 5-HMF in 11 samples of Radix Polygoni Multiflori preparata were from 0.013% to 0.101%, and only one in 4 samples of Radix Polygoni Multiflori containing trace amount of 5-HMF.
CONCLUSIONThe chemical components in Radix Polygoni Multiflori were changed during the processing procedures. Therefore, the processing of Radix Polygoni Multiflori should be controlled and standardized.

OBJECTIVETo observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.
METHODSA total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.
RESULTSThe total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).
CONCLUSIONCDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.
