OBJECTIVETo investigate the efficacy of Chinese medicine Huangban Bianxing Recipe (HBR) for treatment of choroidal neovascularization (CNV).

METHODSEighty patients (97 eyes) suffered from CNV were assigned to two groups, the treated group treated by HBR orally taken one dose every day and the control group treated with ginkgo leaf tablet 1 tablet (19.2 mg) thrice a day, all for 3 months. The best corrected visual acuity (BCVA), fundus hemorrhagic area were measured; the neo-genetic vascular leakage area determined by fluorescent fundus angiography (FFA); and the out-layer high reflective band thickness (OHRBT) estimated by optical coherent tomography (OCT) were recorded before and after treatment.

RESULTSAfter treatment, in the treated group, BCVA was improved, with an effective rate of 67.12%, while in the control group, it was 33.33%, the former was better than the latter significantly (P < 0.05). The effective rate in reducing fundus hemorrhagic area in the two groups (85.11% vs 47.62%) and that in the CNV closure showed by FFA (67.50% vs 37.50%) were also superior in the treated group (P < 0.05). Besides, OCT showed that the OHRBT reduced significantly after treatment in the treated group (P < 0.01).

CONCLUSIONHBR can improve the vision, reduce the CNV leakage in the macular region, and advance the absorption of fundus hemorrhage in CNV patients.

Objective To examine the independent effect of depression on activities of daily living of patients with mild cognitive impairment (MCI). Methods Data were obtained through the face-to-face interview. Totally 154 elderly patients that were screened from 552 old people by the Montreal Cognitive Assessment (MoCA) were diagnosed as MCI. They were investigated with the Geriatric Depression Scale, and instrumental ability of daily living (IADL) were measured by the Functional Activities Questionnaire. The effect of depression on IADL of patients with MCI was analyzed by logistic regression analysis. Results The prevalence of depressive symptoms among Chinese elders with MCI was 31.82％. The scores of Medical Outcomes Study Social Support Survey, and Functional Activity Questionnaire of depression group and non-depression group were significantly different (P<0.05) . Logistic regression analysis showed that scores of Functional Activity Questionnaire was positively associated with the scores of Memory Inventory for the Chinese (OR=1.36, 95％ CI: 1.15-1.61) and depression (OR=6.19, 95％ CI:2.07-18.55) . Conclusion The prevalence of depression in elderly patients with MCI was high. Depression would significantly reduce the IADL of the old patients with MCI. Medical workers should be aware of the extent and impact of depressive symptoms in MCI and take active measures in evaluating and treating the depressive symptoms.

A Marfan syndrome child with contractural arachnodactyly deformity of both hands was admitted to our unit in June 2015. The left and right middle fingers and ring fingers of the child received the continuous " Z" skin flap and " V-Y" plasty to reduce the palmar tension on the skin and release the contracture. Due to the improper therapeutic strategy and the underestimation of effect of underlying lesions of Marfan syndrome on the therapeutic strategy, the right middle finger of child was with ischemic necrosis and amputated, and the finger tip was accompanied with distension and paroxysmal neuropathic pain at a specified future date. The skin flaps of the other three surgical fingers were with local necrosis and scar healing. The child was complicated by distal interphalangeal joints stiffness and some serious complications post-discharge. Combined with this case, the similar disorders are not recommended to carry out one-stage operation.

Ketamine has been used clinically as an analgesic and anesthetic since 1970. Recently, it has been concerned due to its rapid and effective antidepressant effect. However, the psychiatric adverse reactions caused by ketamine such as addiction and hallucination limit its clinical application, yet the mechanism of the adverse reactions is still unclear. At present, it is generally believed that the pharmacological effects of ketamine are mainly mediated by N-methyl-D-aspartate acid (NMDA) receptors, but increasing numbers of research evidences suggest that the opioid receptor also play an important role in the pharmacological effects of ketamine. This review, based on the relevant literature published publicly in the past 20 years, summarizes the mechanisms of opioid receptors in the pharmacological effects of ketamine, such as anesthesia, analgesia, anti-depressant, anti-addiction and addiction, providing reference for revealing the mechanism of ketamine, and making beneficial exploration for solving the clinical side effects of ketamine.

BACKGROUNDHigh levels of nitric oxide (NO) produced by inducible NO synthase (iNOS) have been associated with atherosclerosis processes. Naoxintong is a traditional Chinese medicine for treatment of cerebrovascular and cardiovascular disease. The aim of the present study was to detect and quantify changes of iNOS mRNA and NO levels in the vessel wall after the administration of Naoxintong in an atherosclerotic rabbit model.

METHODSForty New Zealand white rabbits were randomly divided into five groups (n = 8). Rabbits were fed a standard diet (group A), an atherogenic diet consisting of 79% standard feed + 1% cholesterol + 5% lard + 15% egg yolk powder (group B), an atherogenic diet with Naoxintong 0.25 mg×kg(-1)×d(-1) (group C), an atherogenic diet with Naoxintong 0.5 mg×kg(-1)×d(-1) (group D), or atherogenic diet with Naoxintong 1.0 mg×kg(-1)×d(-1) (group E) for 12 weeks.

RESULTSSupplemented administration of Naoxintong led to a down-regulation of cholesterol (CHOL) (P < 0.001) and low-density lipoprotein (LDL) (P < 0.001). The trend became more notable as the dose of Naoxintong increased; group C vs. group B (CHOL, P = 0.568; LDL-cholesterol (LDL-C), P = 0.119), group D vs. group B (CHOL, P = 0.264; LDL-C, P = 0.027), group E vs. group B (CHOL, P = 0.028; LDL-C, P = 0.002). Atherosclerotic lesions in aorta were reduced in Naoxintong groups (groups C, D, E) compared to group B. Group B had higher iNOS mRNA (P = 0.001) and NO level (P < 0.001) than group A. Compared with the atherogenic diet fed-rabbits, Naoxintong supplements decreased the expression of iNOS mRNA (P < 0.001) and the NO level (P < 0.001) in the vessel wall. Groups given a higher Naoxintong dose exhibited greater benefits. iNOS mRNA and NO levels seemed to be reduced in group C, although the difference did not quite reach statistical significance (iNOS mRNA, P = 0.130; NO, P = 0.038). iNOS mRNA and NO levels significantly decreased in group D (iNOS mRNA, P = 0.019; NO, P = 0.018) and group E (iNOS mRNA, P = 0.004; NO, P < 0.001).

CONCLUSIONNaoxintong has beneficial effects on atherosclerosis treatment by reducing expression of iNOS mRNA and the NO level in the vessel wall.

In order to investigate the effect of shRNA targeted to beta-catenin on the growth of K562 cells, plasmid containing beta-catenin specific shRNA sequence was transfected into K562 cells by lipofectamine 2000, and G418 was added to screen the positive cells. Real-time PCR and Western blot were used to detect the expression of beta-catenin. Cell growth curve, MTT and colony forming cell assays were used to evaluate the proliferation potential of cells. The results showed that the mRNA level of beta-catenin was reduced significantly in K562 cells transfected into interfering plasmid as compared with control plasmid, while the protein level failed to demonstrate difference by the time of 72 hours after transfection. After long-term culture with G418, the count of positive cells enhanced in control group while no positive cells survived in the interfering group. Colony-forming cell assays revealed that the K562 cells in interfering group formed colonies with very small size and low forming rate, compared with the control group, though the growth curve and MTT failed to illustrate differences. It is concluded that the beta-catenin-specific shRNA mediated by plasmid can effectively knockdown the expression of beta-catenin gene and inhibit the colony-forming ability in K562 cells, it is a potential target for the therapy of CML, even in blast crisis.

OBJECTIVETo analyse the efficacy and safety of thalidomide (Thal) for patients with multiple myeloma (MM).

METHODSEffectiveness and adverse events of 102 MM patients treated with thalidomide at a median dosage of 200 mg/d. Thirteen cases were treated with Thal alone (group A), and 105 case with Thal in combination with other therapeutic agents (group B) were retrospectively analyzed.

RESULT1) The response rate (RR) (CR + PR) was 65.4% for induction therapy in 52 cases and 45.5% for salvage therapy in 66 cases. RR in group B was higher than that in group A (58.1% versus 23.1/%, P= 0.017), and the non-response/progress (NR) rate was lower (15.2% versus 46.2%, P= 0.015). In group B, the NR rate was lower in 50 cases of newly diagnosed MM than in 55 cases of refractory or relapsed MM (6.0% versus 23.6%, P=0.012). In group B, RR between Thal+VAD or M, regimen (72 cases) and Thal + MP regimen (33 cases) was not statistically significant (62.5% versus 48.5%, P >0.05). 2) The median duration of response maintenance was 15.5 (1.0-58.0) months in 21 cases. 3) Among 97 patients with follow-up data, the estimated median duration of OS was 44 months in a median follow-up duration of 20 months and the accumulative time for use of Thal was 8 months. In univariate analysis,the accumulative duration for use of Thal 6 months, hemoglobin > or = 100 g/L and bone marrow megakaryocytes > 20 per smear were associated with longer OS (P = 0.0014, 0.0101, 0.019, respectively). 4) Multivariate analysis suggested that the accumulative time for use of Thal and bone marrow megakaryocytes > 20 were independent good prognostic factors for OS (P = 0.006, 0.036, respectively). 5) The adverse events of Thal were mostly endurable, the rate of thrombus events was lower than that reported in literature.

CONCLUSIONThalidomide alone or combined with chemotherapy is an useful therapy for MM. The accumulative time for use longer than 6 months may improve survival.
