Objective To comprehend the clinical characteristics and treatment of primary hepatic amyloidosis.Methods A total of 10 cases of primary hepatic amyloidosis included. 4 cases from Peking Union Medical College Hospital and 6 cases from other hospitals.reported in the literature in recent 20 years were reviewed,Results (1)The frequent clinical symptoms related to primary hepatic amyloidosis presented as hepatomegaly(90%),abdominal distension(80%),shifting dullness(60%),anorexia(50%),fatigue(40%),edema(40%),weight loss(40%) and abdominal pain(30%).(2)Laboratory tests revealed elevated serum alkaline phosphatase which was (558.3?517.2)U/L,and other liver function involvement were rare:six patients(85.7%)had either a serum or urine monoclonal protein.(3)Liver biopsy is golden standard.The amyloid deposition was mainly located at sinusoida(4 casese,57.1%),and only 2 cases was at vascular(28.6%).Complication of bleeding after liver biopsy was reported(1 case).(4)The classical therapy scheme was melphalan and prednisone,four cases died from liver function failure and infection.Conclusion The clues to the diagnosis of primary hepatic amyloidosis include elevated monoclonal protein,hepatomegaly and an unexplained elevated serum alkaline phosphatase level which is not parallel with other liver functions.Live biopsy is golden standard.The treatment scheme include melphalan and prednisone,but its prognosis is poor.

OBJECTIVETo investigate the therapeutic effect of alar rotation flap for severe alar retraction.

METHODSPatients with severely retracted alar underwent ala reconstruction using alar rotation flaps and autogenous cartilage batten grafts. First, costal cartilage was used to reshape the nasal tip and nasal dorsum. Then cartilage patch was used to extend and thicken the retracted alar. Then the alar rotation flap was transferred to correct retracted alar.

RESULTSFourteen patients with severe alar retraction underwent alar reconstruction with alar rotation flap and alar batten grafts. The alar retraction was corrected in all cases, with improvements functionally and aesthetically. No recurrence of alar retraction was noted. The incision healed with acceptable cosmetic results, with obvious scar in only one patient (one side).

CONCLUSIONSThe alar rotation flap is an effective and reliable surgical option to correct severe alar retraction. Scar can be kept inconspicuous by precise placement of the incision within the junction of the ala and the nasal dorsum, following principles of the aesthetic nasal subunits.

METHODS: 133 cases of active pulmonary tuberculosis patients were divided into two groups.The clinical effects of two groups were compared and Tlymphocyte subsets were detected. RESULTS: The total effective rate was 95.8%,its efficacy was superior to the control group(P

To study the influence of individualized medication guidance based on an Short Messaging Service( SMS) platform on the medication compliance in the patients with diabetes. Methods: Totally 100 cases of diabetic patients from the outpa-tient section were randomly divided into two groups using a number method with 50 ones in each, namely odd number was in the obser-vation group and even number was in the control group. The observation group was given pharmaceutical guidance based on the SMS technology platform by pharmacists, and the control group was given telephone follow-up once a week to understand the medical situa-tion. At the beginning of the study and after three-month treatment, the medication compliance in the two groups was evaluated, and the control situation of blood glucose was also compared. Results:There was no significant difference in the medication compliance be-tween the two groups at the beginning (P>0. 05). After the 3-month treatment, the blood glucose and medication compliance between the two group had statistical significance (P<0. 01). Conclusion:Based on a mobile phone short message technology platform, indi-vidualized clinical pharmaceutical guidance can significantly improve the medication compliance in diabetic patients.

Objective To investigate the efficiency and mechanism of differentiation of reprogrammed adipose-derived stem cells (ADSCs) to neurons in vitro.Methods ADSCs from rats were cultured in vitro and then purified and identified.ADSCs at the third passage were divided into three groups:ADSCs without lentivirus-mediated gene transfection (blank group),ADSCs transfected with lentivirus carrying no neurogenin2 (Ngn2) (empty virus group) and ADSCs with lentivirus-mediated transfection of Ngn2 (Ngn2 group).All groups were induced in the medium containing cell growth factor for 15 days.The positive expression of neuron-specific nuclear protein (NeuN) in three groups was detected using immunofluorescence method so as to observe the efficiency of neuron differentiation.Expression variances of Mash1,Hes1 and Dll1 in each group were detected by Western blot analysis and the mechanism of differentiation was also discussed.Results After 15 days of induction,positive expression rate of NeuN in Ngn2 group,empty virus group,blank group was 90.12％,45.34％ and 40.26％ respectively,with significant differences among groups (P ＜ 0.01).Western blot analysis showed that Ngn2 group had a significantly higher expression of Dll1 (P ＜0.01) and obvious lower expressions of Hes1 and Mash1 (P ＜0.01),as compared with empty virus group and blank group.However,there were no significant differences of expression levels of Dll1,Mash1 and Hes1 between empty virus group and blank group (P ＞ 0.05).Conclusions After induction,the ratio of neuron differentiation of reprogrammed ADSCs is increased by almost 99％,as compared with simple ADSCs.The increased dfferentiation of reprogrammedADSCs to neurons may be associated with the inhibition of notch signaling through up-regulating Dll1 and down-regulating Mash1 and Hesl.

Objective To evaluate the impact of small interference RNA (siRNA)-induced silencing of adrenomedullin (ADM) gene on the growth of and apoptosis in a malignant melanoma cell line A375.Methods Three siRNAs targeting ADM gene were constructed and transfected into A375 cells.Real-time quantitative reverse transcription PCR (qRT-PCR) was performed to measure the expression of ADM to select the most efficient siRNA for the next experiment.A375 cells were classified into 3 groups to be transfected with the selected siRNA (test group),non-specific sequences (negative control group),or remain untransfected (blank control group).Then,an immunohistochemical SP method was used to determine the expression of ADM at 24hours,methyl thiazolyl tetrazolium (MTT) assay to detect the proliferation of A375 cells at 24 and 48 hours,flow cytometry to observe cell apoptosis at 48 hours.Results qRT-PCR showed that ADM-siRNA-2 was the most efficient.The expression of ADM was significantly lower in the test group than in the other two groups.The proliferation level (represented as the absorbance value at 490 nm) of A375 cells was 0.389 ± 0.0375 and 0.469 ± 0.0330 in the test group at 24 and 48 hours respectively,significantly lower than that in the negative control group (0.548 ± 0.0376,0.676 ± 0.0374,both P＜ 0.05) and blank control group (0.574 ± 0.0733,0.685 ± 0.0154,both P ＜ 0.05).Flow cytometry revealed a statistical increase in early apoptosis rate in the test group compared with the blank control group and negative control group ((20.200 ± 6.046)％ vs.(1.667 ± 0.340)％ and (4.587 ± 1.294)％,both P ＜ 0.05).No significant differences were observed in the proliferation level or early apoptosis rate between the negative control group and blank control group (both P ＜ 0.05).Conclusion The siRNA-induced silencing of ADM gene can inhibit the proliferation of,but promote the apoptosis in,A375 cells.

Objective To investigate the expression of nestin protein and insulin-like growth factor 1(IGF-1) mRNA in rat brain injured by ischemia-reperfusion(I/R),and observe the effects of Tongxinluo,one of Chinese herb drugs,on the expression.Methods The rat model of cerebral I/R injury,reproduced by middle cerebral artery occlusion(MCAO) and release,were divided into three groups: high-dose Tongxinluo group(given 1g/kg?d of Tongxinluo],low-dose Tongxinluo group(given 0.5g/kg?d of Tongxinluo) and control group(administration of saline).2ml of Tongxinluo or saline each time was administered to each rat and 2 times every day up to day 3,5,7,14,21 and 30 after the injury.The expression of nestin in the subventricular zone(SVZ) and hippocampal dentate gyrus zone(DG) was detected by immunohistochemistry,and the IGF-1 mRNA expression around ischemic area was detected by RT-PCR.Results Compared with the control group,the immunofluorescence magnitude of nestin-positive neurons in SVZ and DG was significantly higher in high-and low-dose Tongxinluo groups(P0.05).Conclusions Tongxinluo,a kind of Chinese herb drugs,may promote the proliferation of neural stem cells in SVZ and DG after cerebral I/R injury in rats,and the mechanism may be related to upregulation of IGF-1 mRNA induced by Tongxinluo.
