Objective: To observe the clinical efficacy of acupuncture plus subtle adjustment manipulation of the cervical spine for peripheral facial paralysis.Methods: A total of 60 patients with peripheral facial paralysis who met the screening criteria were selected and divided into two groups according to the method of random number table, with 30 cases in each group. The patients in the acupuncture plus tuina group received routine treatment of acupuncture and subtle adjustment manipulation of the cervical spine, while the patients in the acupuncture group only received the same acupuncture treatment. Assessment of peripheral facial paralysis with integrated traditional Chinese and Western medicine was adopted for rehabilitation assessment. Results: The total effective rate of the acupuncture plus tuina group was 93.3％, while that of the acupuncture group was 70.0％, and there was a significant between-group difference (P<0.05). After treatment, the total scores of rehabilitation assessment in both groups were significantly higher than those before treatment (both P<0.05), and the score of the acupuncture plus tuina group was significantly higher than that of the acupuncture group (P<0.05). Conclusion: The treatment of acupuncture plus subtle adjustment manipulation of the cervical spine can improve the function of facial muscles in patients with peripheral facial paralysis, and its clinical efficacy is better than that of the acupuncture treatment alone.

Objective To monitor the quality changes of iodized salt and analyze its impact factor in Chongqing between 2001 and 2009. Methods Salt samples were collected according to the east, west, south,north and center locations in iodized salt production, wholesale and household sectors. Two units in iodized salt production and wholesale segment were sampled from north, south, east and west places and only 1 unit was sampled from the central place. Nine samples were collected every month in each place. If the place had less than 9 units, and then taken all the units. About resident household, 2 townships were sampled from north, south, east and west places, and 1 township was sampled from the central place, then 20 samples were collected from each township. Iodine content was detected by oxidation-reduction assay. The index of mean iodine, qualified rate from factories and wholesale, coverage rate and taking rate of qualified iodized salt in residents were calculated.Significance was analyzed by trend test, analysis of variance and X2 test. Results The qualified rate of iodized salt from the manufacturers was 92.9%(13/14) in 2001 and the rate was 100.0% each year from 2002 to 2009. The qualified rates of iodized salt from the wholesale were 88.7%(282/318) - 99.8%(431/432). The rates of 2001 and 2002 were lower than that of other years(X2 = 4.98 - 45.69, all P< 0.05 or < 0.01). The coverage rate and taking rate of qualified iodized salt in residents were 94.2% (11 154/11 841 ) - 98.9% ( 14 061/14 217), 83.5% (9 887/11 841 ) -95.8% (13 449/14 039), respectively. The rates showed an increasing tendency (F = 9.27, 26.39, all P < 0.05).The districts(counties) with qualified iodized salt consumption rate > 90% kept increasing. The mean iodine from the manufacturers and wholesale were 29.71 - 36.25, and 31.26 - 36.13 mg/kg, respectively. The iodine level showed a descending trend(F = 35.45, 140.59, all P < 0.01 ). The mean iodine level from the inhabitants were 28.84 - 30.98 mg/kg which remained stable (F = 3.05, P > 0.05 ). The iodine level from manufacturers, wholesale to inhabitants showed an descending trend(F = 38.46 - 671.23, all P < 0.01 ). Conclusions The surveillance results of iodized salt shows an increasing tendency in quality of iodized salt, eoverage rate and taking rate of qualified iodized salt. Factors that affect the quality of iodized salt is that the enterprise does not add iodine to salt strictly by the standard.

OBJECTIVETo investigate the effects of chronic stress on the spatial learning-memory and the role of glial cell line-derived neurotrophic factor (GDNF) of prefrontal cortex (PFC) and hippocampus (HP) in different age mice.

METHODSThe chronic stress model mice in 21 days with multiple chronic unpredictable stressors were applied. The spontaneous behavior and spatial learning-memory ability of mice were tested, using Open field and Morris water maze task, and the expression of GDNF in HP and PFC were detected by immunohistochemical method.

RESULTSCompared with young mice, the spontaneous behaviors were significantly decreased and the spatial learning-memory function were significantly decreased (P < 0.05, P < 0.01) in aged mice. The GDNF expression in the CA3, DG of HP and PFC were significantly reduced in aged mice (P < 0.05, P < 0.01). After chronic stress, the spontaneous behaviors were remarkably decreased and the ability of spatial learning-memory of the stress group mice were significantly decreased (P < 0.05, P < 0.01) compared with those of the control group mice. The expression of GDNF in HP and PFC were remarkably reduced (P < 0.05, P < 0.01) in stress group mice. The aged stress mice had more serious changes after chronic stress.

CONCLUSIONThe brain aging and chronic stress in mice causes behavioral changes and the damage of spatial learning-memory function, and which may be nearly related to the expression of GDNF in HP and PFC.

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.

The aim of this study is to prepare hyaluronic acid (HA) modified core-shell liponanoparticles (pHA-LCS-NPs) as gene delivery system and investigate its gene transfection efficiency in human retinal pigment epithelium (ARPE-19) cells in vitro. The pHA-LCS-NPs was prepared by firstly hydrating dry lipid film with CS-NPs suspension to get LCS-NPs, then modifying the lipid bilayer with HA by amidation reaction between HA and dioleoyl phosphatidylethanolamine (DOPE). Its morphology, particle size and zeta potential were investigated. XTT assay was used to evaluate the cell safety of different vectors in vitro. The gene transfection efficiency of pHA-LCS-NPs modified with different contents of HA was investigated in ARPE-19 cells with green fluorescent protein (pEGFP) as the reporter gene. The results showed that the obtained pHA-LCS-NPs exhibited a clear core-shell structure with the average particles size of (214.9 +/- 7.2) nm and zeta potential of (-35 +/- 3.7) mV. The 24 h cumulative release of gene from pHA-LCS-NPs was less than 30%. After 48 h incubation, gene transfection efficiency of pHA-LCS-NPs/pEGFP was 1.81 times and 3.75 times higher than that of CS-NPs/pEGFP and naked pEGFP, respectively. Also no obvious cytotoxicity was observed on pHA-LCS-NPs. It suggested that the pHA-LCS-NPs might be promising non-viral gene delivery systems with high efficiency and low cytotoxicity.

OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.

METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.

RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).

CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.

AIM: To investigate the clinical characteristics, surgical outcome and curative effect of congenital fibrosis of the extraocular muscles ( CFEOM) .
METHODS: The eye exam of members in a Chinese family with CFEOM includes visual acuity, intraocular pressure, dilated fundus exam, extraocular muscle function test, orbital CT scan, and ultrasound. We did extraocular muscle surgery or frontalis suspension procedure for affected subjects in the family.
RESULTS: The incidence of CFEOM in this family was 31%. All patients were affected bilateraly with symptom of congenital eye movement disorder, ptosis, hypotropia, perverted convergence on upgaze and chin up head position. As the age grows, the diseases worsen unobviously. No other systemic disorder was found. Surgical treatment improved the anomalous head position although the ocular movement disorder preserved.
CONCLUSION: The pattern of inheritance in our serial patients are autosomal dominant. Surgery can improve chin up head position and cosmetic appearance. However, the eye movement deficiency cannot be improved.
