AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.

Ageing is the most significant risk factor for a range of prevalent diseases, including cancer, cardiovascular disease, and diabetes. Accordingly, interventions are needed for delaying or preventing disorders associated with the ageing process, i.e., promotion of healthy ageing. Calorie restriction is the only nongenetic and the most robust approach to slow the process of ageing in evolutionarily divergent species, ranging from yeasts, worms, and flies to mammals. Although it has been known for more than 80 years that calorie restriction increases lifespan, a mechanistic understanding of this phenomenon remains elusive. Yeast silent information regulator 2 (Sir2), the founding member of the sirtuin family of protein deacetylases, and its mammalian homologue Sir2-like protein 1 (SIRT1), have been suggested to promote survival and longevity of organisms. SIRT1 exerts protective effects against a number of age-associated disorders. Caloric restriction increases both Sir2 and SIRT1 activity. This review focuses on the mechanistic insights between caloric restriction and Sir2/SIRT1 activation. A number of molecular links, including nicotinamide adenine dinucleotide, nicotinamide, biotin, and related metabolites, are suggested to be the most important conduits mediating caloric restriction-induced Sir2/SIRT1 activation and lifespan extension.

Artificial intelligence (AI), represented by deep learning (DL)has made a major breakthrough in computer vision tasks. The applications and developments of AI in medical image analysis were reviewed from four groups corresponding to four classical computer vision tasks, namely, image classification, object detection, semantic segmentation and image synthesis.

Objective To explore the effect of speech therapy on articulation disorder of indifferent kinds of children with cerebral palsy(CP).Methods 49 CP children with articulation disorder were divided into the common group(n=21)and family rehabilitation group(n=28).All children in the two groups were treated with systemic speech therapy,but those in the family rehabilitation group were added with family rehabilitation.The changes of articulation disorder of children in two groups before and after treatment were observed.Results After treatment,all children got improvement,but the effect of children with spastic type was superior to those with other CP types.The efficiency rate of the family rehabilitation group was 39.3%,that of the common group was 14.3%,there was a significant difference between two groups(P<0.05).Conclusion The children with different CP type have different therapeutic effects for articulation disorder,the family rehabilitation can improve the therapeutic effect.

Transdermal drug delivery systems (TDDs) avoid gastrointestinal degradation and hepatic first-pass metabolism, providing good drug bioavailability and patient compliance. One emerging type of TDDs is the wearable patch worn on the skin surface to deliver medication through the skin. They can generally be grouped into passive and active types, depending on the properties of materials, design principles and integrated devices. This review describes the latest advancement in the development of wearable patches, focusing on the integration of stimulus-responsive materials and electronics. This development is deemed to provide a dosage, temporal, and spatial control of therapeutics delivery.

Electronic skin has shown great application potential in many fields such as healthcare monitoring and human-machine interaction due to their excellent sensing performance, mechanical properties and biocompatibility. This paper starts from the materials selection and structures design of electronic skin, and summarizes their different applications in the field of healthcare equipment, especially current development status of wearable sensors with different functions, as well as the application of electronic skin in virtual reality. The challenges of electronic skin in the field of wearable devices and healthcare, as well as our corresponding strategies, are discussed to provide a reference for further advancing the research of electronic skin.

Metastasis from unknown primary is always a challenge because finding the true primary tumor significantly affects subsequent management. We present a case of malignant abdominal wall nodule initially diagnosed as metastasis from hepatocellular carcinoma through excisional biopsy and immunohistochemical (IHC) staining. Dual-tracer positron emission tomography/computed tomography (PET/CT) with 11 C-acetate and 18 F-FDG, however, showed metabolic findings in favor of metastasis from lung origin, which was finally confirmed by ensuing a lung biopsy with additional IHC stains. This case illustrates the complementary molecular role of PET to pathology, particularly when dual-tracer or multi-tracer PET is used in conjunction with pathology methods for cross referencing and confirmation.

OBJECTIVE: To investigate the immediate analgesic effect of sinew acupuncture for patients with soft-tissue injuries (STIs). METHODS: Two hundreds eligible adult patients suffering from STIs were recruited and received sinew acupuncture with flexible treatment schedules. The number of treatment sessions was pragmatically decided by each patient on the basis of their pain relief. The outcome measurement was the change of pain rating in the Visual Analogue Scale (VAS) during the first 5 sessions. The adverse effect was also observed. RESULTS: Of the 200 patients recruited, 7 were excluded due to incomplete data. In total, 888 sinew acupuncture treatments were administered to patients at 14 injury sites (including head, neck, shoulder, arm, chest, elbow, wrist, hand, waist and hip, knee, thigh, calf, ankle, and foot) where pain was felt. Compared with the baseline, the VAS rating after the first and last treatments were both significantly reduced at all the injury sites (P<0.01). The VAS rating was also significantly reduced after each session of treatment in the first five sessions (P<0.01). No serious adverse effect was observed. CONCLUSION Sinew acupuncture had not only an immediate analgesic effect for STIs, but also an accumulated analgesic effect during the first 5 treatment sessions.

OBJECTIVETo assess the biological effects of the six-herb mixture Anti-Insomia Formula (AIF) extract using caffeine-induced insomnia Drosophila model and short-sleep mutants.

METHODSCaffeineinduced insomnia wild-type Drosophila and short-sleep mutant flies minisleep (mns) and Hyperkinetic(Y) (Hk(Y)) were used to assess the hypnotic effects of the AIF in vivo. The night time activity, the amount of night time sleep and the number of sleep bouts were determined using Drosophila activity monitoring system. Sleep was defined as any period of uninterrupted behavioral immobility (0 count per minute) lasting > 5 min. Night time sleep was calculated by summing up the sleep time in the dark period. Number of sleep bouts was calculated by counting the number of sleep episodes in the dark period.

RESULTSAIF at the dosage of 50 mg/mL, effectively attenuated caffeine-induced wakefulness (P<0.01) in wild-type Canton-S flies as indicated by the reduction of the sleep bouts, night time activities and increase of the amount of night time sleep. AIF also significantly reduced sleeping time of short-sleep Hk(Y) mutant flies (P<0.01). However, AIF did not produce similar effect in mns mutants.

CONCLUSIONAIF might be able to rescue the abnormal condition caused by mutated modulatory subunit of the tetrameric potassium channel, but not rescuing the abnormal nerve firing caused by Shaker gene mutation. This study provides the scientific evidence to support the use of AIF in Chinese medicine for promoting sleep quality in insomnia.
