Peripheral nerve injury of a limb usually causes functional reorganization of the contralateral somatosensory cortex.However, the patients with an operation of the contralateral seventh cervical nerve (C7) transfer to an injured arm with brachial plexus root avulsions usually have the sole tactile sensibility of the healthy hand when the injured hand is touched at the early stage after the operation. Then, at later stage they gradually get normal sense from the injured and the normal hands independently. Mimicked the process in a rat model based on the above operation, representations of the injured forepaw and the healthy forepaw in the somatosensory cortex were studied by means of somatosensory evoked potential (SEP) recording. Somatosensory function shown in SEP response amplitude and peak latency of the injured forepaw gradually recovered with time after the operation due to the contralateral C7 regeneration toward the injured limb, accompanied with the recovery process of limb movement. The somatosensory representation of the injured forepaw was observed exclusively in the ipsilateral somatosensory cortex since the 5th month after the operation. Accordingly, the overlapped representation of the injured and healthy forepaws emerged in the ipsilateral somatosensory cortex of 13 rats studied except one with separated representation though the SEP latency and response amplitude were different in responding to stimuli on the two forepaws. It is concluded that the contralateral peripheral nerve transfer to the injured arm can cause dynamically functional reorganization in the ipsilateral somatosensory cortex suggesting a remarkable plasticity of the brain function induced by an alteration of sensory input between two sides of the body in adult rats.

Objective To evaluate the efficacy and safety of hydroxychloroquine sulfate (HCQ) on pregnancy outcomes in patients with systemic lupus erythematosus (SLE). Methods One hundred and sixty-six pregnant patients with SLE from Janurary 2010 to December 2015 were studied retrospectively . Fifty-two patients were excluded due to new-onset during pregnancy, active disease or termination of pregnancy as a result of continuous intaking of immunosuppressant. The remaining 114 SLE patients in stable condition before pregnancy were divided into the following two groups: prednisone combined with HCQ and prednisone alone. The effects of HCQ on disease activity and pregnancy outcome were analyzed. Differences between groups were analyzed by chi-square test. Results A total of 90 patients (78.9%) had successful pregnancy. Among 71 patients treated with prednisone combined with HCQ, 60 patients (84.5%) had no disease flare and 62 cases (87.3%) had successful pregnancy. Among 43 patients treated with prednisone alone, 28 patients (65.1%) had no disease flare and 28 cases (65.1%) had successful pregnancy. No abnormality of neither visual field nor fundus was observed among patients treated with HCQ. No congenital abnormalities were found among new born infants. Conclusion HCQ intake during pregnancy in SLE patients can reduce disease flare and improve the pregnancy outcome, indicating that HCQ is safe for SLE patients during pregnancy.

Objective: To investigate the clinical efficacy of nalmefene hydrochloride in the treatment of patients with traumatic shock. Methods:Totally 62 cases of patients with traumatic shock were randomly divided into nalmefene treatment group (n=31) and the control group ( n =31 ) according to the random number table. The control group was given the conventional treatment, while nalmefene treatment group was treated with nalmefene hydrochloride additionally. The changes of hemodynamics, plasma TNF-αand vas-cular endothelial function index were compared between the groups. Results:The mean arterial pressure in 24h after the treatment signifi-cantly decreased when compared with that in 12h after the treatment of nalmefene treatment group, and the difference was statistically sig-nificant (P<0. 05);the heart rate in 12h and 24h after the treatment in nalmefene treatment group significantly decreased when com-pared with that before the treatment, and the differences were statistically significant (P<0. 05);the plasma TNF-αlevels in 24h after the treatment in nalmefene treatment group significantly decreased when compared with that in 12h after the treatment, and the difference was statistically significant (P<0. 05), and there was no significant difference in plasma TNF-α levels before the treatment and in 12h after the treatment (P<0. 05);the plasma NO and ET in 24h after the treatment in nalmefene treatment group significantly decreased when compared with that in 12h after the treatment, and the difference were statistically significant (P<0. 05);and there was no signifi-cant difference in plasma NO and ET before the treatment and in 24h after the treatment (P<0. 05);abnormality in electrocardiogram, routine blood tests, routine urine and liver and renal function examinations were not found, and no obvious adverse drug reactions were shown during the treatment course. Conclusion:Nalmefene hydrochloride combined with the conventional treatment in the patients with traumatic shock shows striking efficiency with notable effects on hemodynamics ( heart rate and mean arterial pressure) , which can reduce plasma TNF-α, NO and ET levels and shows significant research significance.

Objective To study the role of down regulation of bcl 2 expression of human cholangiocarcinoma cells with bcl 2 mRNA cleaving ribozyme (RZ). Methods Synthetic gene of bcl 2 mRNA cleaving RZ was recombined with the expression vector of eukaryotic cells. The recombined vector was used to transfect human cholangiocarcinoma cells. The expression of bcl 2 in human cholangiocarcinoma cells was observed by immunocytochemistry and flow cytometry. Results The expression of bcl 2 in human cholangiocarcinoma cells transfected with RZ gene was lower than that of control group. Spontaneous apoptosis was observed in a few of the cells. Conclusion bcl 2 mRNA cleaving RZ can down regulate the expression of bcl 2 of cholangiocarcinoma cells notably and can also induce spontaneous apoptosis.

Objective To investigate spiral CT,PET/CT and clinical manifestations in non-HIV infectious penicilliposis marneffei lung disease, to improve diagnostic level of this disease.Methods Imaging manifestations of 6 cases of non-HIV infectious penicilliposis marneffei confirmed by bronchofiberscope lung biopsy and/or pus culture were analyzed retrospectively All cases underwent chest CT,two had brain MRI,and two had PET/CT scan before treatment.Imaging appearances were observed and combined with clinical dates and literatures.Results Unilateral lung lesion was detected in 1 case,bilateral lungs lesions in 5 cases.Multiple patchy consolidation,stripe shadow in bilateral lungs or right lung were found in 3 cases, multiple nodes in 2 cases, mass with nodes in 1 case.Among 6 cases, 2 had septa interlobulare thickness,1 had tracheal fistula,2 had pericardium and pleura involvement,4 had bone destruction,1 had the brainand liver involvement.6 cases showed multiple lymphadenectasis,amalgamation and necrosis in bilateral hilar,mediastinaand the neck.2 had abdominal cavity and or retroperitoneal lymphadenectasis.On PET/CT,2 cases showed high uptake,and the range of SUV value were 1.4-13.9.Initial misdiagnosis by imaging was found in 5 cases.6 patients recovered after anti fungus treatment.Conclusion Imaging appearances of non-HIV infectious penicilliposis marneffei mainly reveals as multiple patchy consolidation,nodes and mass in bilateral lungs, all accompany with lymphadenectasis, many with bone destruction,lack of specificity, which needs lesion biopsy and pus culture to make confirmed diagnosis.

Purpose　To study the relationship between sympathetic nerve and the branches of primary sensory neurons in dominating cervical zygapophyseal joints with the HRP retrograde tracing methods.To explore the mechanism of the external intervertebral foramen's cryical nerve compression syndrome with neck-shoulder pain and the symptom of head and face regions.　Methods　8 Wistar rats were used with the right side as experimental side and the left side as control side.5 μl of 30% HRP solution was injected into the C5/C6 cervical zygapophyseal joint capsule of the right side by microinjection syringe and 5 μl of 0.9% normal saline was injected into the left side as control.The animals survived for 48 hours and were killed by perfusing through ascending aorta.The C1-T1 DRG,cervical sympathetic ganglia and trigeminal ganglia on both sides were sectioned by frozen section method,and treated with TMB method.The HRP labeled cells in sections were observed under optical microscope.The classification and count of HRP labeled cells in DRG and cervical sympathetic ganglia on experimental sides were analysed by image pattern analysis system.　Results　There were HRP labeled cells in middle cervical ganglia,inferior cervical ganglia (stellate ganglia) and C5-C7 DRG on experimental sides after HRP injection.Most of the labeled cells were small or middle size.The sum of mean area and the mean optical density of HRP labeled cells were larger in the middle cervical ganglia and C6 DRG than that in inferior cervical ganglia(stellate ganglia) and C5 or C7 DRG separately (P<0.01).There wasn't any HRP labeled cell in C1-T1 DRG of control side and in trigeminal ganglia.　Conclusions　The cervical zygapophyseal joint mainly dominated by the sensory branches of the three cervical nerves next to it and by the branches of the sympathetic nerves.It may be related to the causing of neck-shoulder pain and the symptoms of head and face regions of patients with the external intervertebral foramen's cervical nerve compression
