Objective To investigate the clinical, electrophysiological and pathological features of critical illness polyneuropathy and myopathy (CIPNM). Methods The clinical outcomes, electromyogram Results as well as pathological features in nerves and muscles of 3 patients with CIPNM were investigated and analyzed. Results 3 patients were all provided with assisted respiration after tracheal intubation. 7~10 d after intubation, all the patients emerged muscle strength and tendon reflexes of extremities weakening; while 14 days after that, 2 patients appeared amyotrophy of extremities. Electromyogram showed that the conduction of many motor and sensory nerves for extremities decreased, while the amplitude of compound muscle action potential (CMAP) of part of motor nerves decreased. Biopsy for nerves revealed decreased medullated nerve fibers and regeneration phenomenon of auxiliary fibers; while that for muscles showed neuralgic damage and myopathy-like changes. Conclusion CIPNM can complicate after tracheal intubation. The electrophysiological and pathological examinations for nerves and muscles can be helpful for the diagnosis.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.
METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.
RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.
CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

Hepatolenticular degeneration was one of the rare several genetic metabolic diseases in clinic that could be cured by liver transplantation method, developing slowly and being irreversible. Metabolic disorders of copper lead to abnormal copper accumulation in various of tissues and organs. So that, the disease′s clinical manifestations were lacking in specificity and many patients missed the best opportunity of drug treatment. With the maturity of technologies and innovation of theory of liver transplantation, there were more and more methods that will be applied to personalized treatment. In this paper, a review of the research progress in the treatment of hepatolenticular degeneration with liver transplantation was made with reference to the relevant literature at home and abroad.

Neuroendocrine tumors (NETs) is a rare and heterogeneous group of tumors with widely varying morphologies and behaviors. Due to their rarity and heterogeneity, progress in improving its treatment has been slow. Pancreatic neuroendocrine tumors (pNETs) is a subset of NETs, previously known as islet cell tumors, occupies 3% of the primary pancreatic tumors with the annual incidence rate of (1-2)/100 000. In recent years, it is very necessary to improve the diagnosis and treatment of pNETs.

Objective To prepare a thrombus-targeted ultrasonic contrast agent and to investigate its targeted ability to fresh blood clots. Methods We first synthesized FITC-KGDS-Palm compound, and then prepared thrombus-targeted microbubbles using "ultrasound & high speed shearing method".Fluorescence labeling thrombus-specific peptides and KGDS,directed at the activated glycoprotein(GP)Ⅱb/Ⅲa receptor of platelets were attached to the surface of lipid microbubbles. The concentration and size of TUCA were measured by Malvern Zeta Sizer Nano-ZS590 and Coulter counter.Immunofluorescence was applied to confirm the conjugation.The conjunct ratio was assessed by flow cytometer (FCM).Results The KGDS-TUCA was straw yellow turbid liquor,and the concentration was 1.5×10~9/mL,and the average size was 1.5 μm. The targeted microbubbles conjugated with the thrombus-specific peptides showed bright green rings by fluorescence microscope.FCM demonstrated that the wavelength of shell of KGDS-TUCA changed greatly,and the conjunct ratio was 90.04%.In vitro study showed KGDS-TUCA remained stable for 48 h at 4 ℃ and target-attached to blood clots and showed good stability.Conclusion The ultrasound & high speed shearing method to prepare TUCA is easy and in favor of purification.KGDS-TUCA has high specific biological activity.The conjunct ratio and stability of KGDS-TUCA are excellent.

Objective To compare the clinical characteristics of multiple sclerosis ( MS) and neuromyelitis optica (NMO) for better diagnosis and differential diagnosis of them. Methods The characteristics of 40 MS and 38 NMO cases were retrospectively studied on clinic manifestations, electroneurophysiology,some laboratory indices, imaging characteristics and so on. Results The ratios of male to female were 1: 1. 35 and 1:4. 43 respectively in patients with MS and NMO, so patients with NMO were more likely to be female as compared with MS ( P < 0. 05 ). The mean onset age was ( 35. 5 ±13. 9 ) years in MS patients and (30. 6 ± 15. 6) years in NMO patients, but no significant difference was found (P>0. 05). The cases of visual acuity ≤0.1 in patients NMO was 13, which of MS was merely 1. The cases of visual acuity less than 0. 5 after treatment in NMO patients was 19, which in MS was only 1. The cases of cognitive impairment in NMO was 3, which of MS was 10. The cases of cerebrospinal fluid oligoclonal bands in MS was 16, which in NMO patients was 9. The lesions of spinal cord shown in MRI of MS patients were typically oval, peripheral and asymmetric, but those in NMO patients extended longitudinally and converged centrally. The mean number of involved vertebral segments in NMO patients was significantly greater than that in MS patients ( 6. 6 vs 2. 2, P < 0. 01). Furthermore, the number of spinal cord lesions in MS patients was alse remarkably greater than that in NMO patients (2. 0vs1.2, P <0. 01). Conclusions NMO may be a distinct clinical entity, which is likely to be differentiated from MS by its tendency to affect women, younger age at onset, and other features clinical manifestations, electroneurophysiology, laboratory parameters, neuroimaging show..

Objective To explore the value of brain CT scanning for distinguishing tumor-like inflammatory demyelinating diseases (TIDD) from glioma or primary central nervous system lymphoma.Methods The brain CT features in 20 patients with TIDD(10 female,10 male;mean age (35.6±14.0)years;range,6-51 years)and 32 gliomas(16 female,16 male;mean age(42.0±19.8)years;range,12-75 years)and 6 lymphomas(3 female,3 male;mean age(53.8±11.8)years;range,32-68 years)were retrospectively reviewed and compared between brain tumors and TIDD.Results (1)Among the 38 primary brain tumors,there were 19 cases(50%,14 gliomas,5 lymphomas)with hyperdense lesions,10 cases(26.3%,9 gliomas,1 lymphomas)with isodense lesions,and 9 glionms (23.7%)with hypodense lesions.In contrast,the brain unenhanced CT manifestation of 20 TIDD all showed with hypodense lesions.(2)On unenhanced CT the lesions of 6 lymphomas all were hyperdense or isodense,like 90% of 20 high grade gliomas(WHO grade Ⅲ and Ⅳ),but this rate for grade Ⅱ was only 41.7%.(3)According to the shape of hyperdense lesions of the 19 primary brain tumors with,7 cages(6 gliomas,1 lymphomas)manifested with asymmetric hyperdense small-patches,4 cases(1 gliomas,3 lymphomas)with symmetric hyperdense large-patches,4 cases(3 gliomas,1 lymphomas)with diffused hyperdensed lesions,and 4 cases(4 gliomas)with ring-shaped hyperdensed lesions.Furthermore,4 primary brain tumors(4 lymphomas)underwent CT enhanced scanning and all the cases showed strong enhancement(3 cases with hyperdense lesions and 1 with isodense lesions on unenhanced CT),but only 3 cases of 7 TIDD showed mild enhancement in contrast.(4)By Spearman's relevant analysis,hyperdense and isodense on unenhanced CT was proved to have significant positive correlation between the grade of gliomas(r=0.435,P=0.013).Therefore,the frequency of hyperdense and isodense lesions in lymphomas and WHO grade Ⅲ and Ⅳ astrocytoma was higher in contrast with low grade astrocytoma.Conclusions Brain CT as a simple,economical and practical examination method has significant meaning for differentiating TIDD from glioma or PCNSL and could be used as an adjuvant method for MRI and magnetic resonance spectroscopy.Patients with hyperdense or isodense on unenhanced CT or strong enhancement could be excluded from TIDD.
