OBJECTIVE: To investigate the effect of relaxing needling at the contracted sites of meridian-muscle regions in the patients with post-stroke shoulder-hand syndrome (SHS) at acute stage. METHODS: Eighty patients with post-stroke SHS at acute stage were randomized into an observation group (40 cases, 1 case dropped out) and a control group (40 cases, 1 case was eliminated). In the control group, the routine medication, basic rehabilitation training, and hyperbaric oxygen therapy were administered. In the observation group, besides the treatment as the control group, relaxing needling was delivered at the contracted sites of meridian-muscle regions. These contracted sites were distributed along three yin meridians of hand and three yang meridians of hand on the affected upper limbs. The intervention was given once daily, 5 times a week and for 4 weeks. Before and after treatment, the scores of visual analogue scale (VAS) for pain, edema degree, modified Barthel index (MBI), and Fugl-Meyer assessment (FMA) for motor function, and the integrated electromyography (iEMG) of surface electromyogram (sEMG) were observed in the two groups. The curative effect was evaluated after treatment and in follow-up of 2 months after treatment in the two groups. RESULTS: After treatment, VAS scores and the scores of edema degree were reduced when compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). MBI and FMA scores increased after treatment compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05) after treatment. The iEMG values of the biceps brachii, triceps brachii, and wrist extensors were elevated after treatment in comparison with those before treatment (P<0.05) in the two groups, and the values in the observation group were larger than those in the control group after treatment (P<0.05). The total clinical effective rate in the observation group was 92.3% (36/39), which was better than that of the control group (74.4%, 29/39, P<0.05) after treatment; and that of the observation group was 97.4% (38/39), which was better than 82.1% (32/39) in the control group (P<0.05) in follow-up. CONCLUSION Relaxing needling at the contracted sites of meridian-muscle regions in treatment of post-stroke SHS at acute stage can attenuate the symptoms such as upper limb pain, swelling and spasm, improve motor function and the activity of daily living of patients.

Objective To investigate the clinical features of cutaneous adverse reactions to tyrosine kinase inhibitors.Methods Thirty patients with cutaneous adverse reactions to tyrosine kinase inhibitors were enrolled from the First Affiliated Hospital of Guangzhou Medical University between January 2015 and December 2016,and their laboratory test results,histopathological findings and treatment response data were collected and analyzed retrospectively.Results Of the 30 patients,15 presented with acneiform eruptions,10 with eczematoid eruptions,2 with morbilliform rashes,1 with telangiectasia,1 with hand-foot skin reaction,9 with xerosis,7 with nail changes and 4 with hair changes.A patient with grade 4 acneiform eruptions showed a markedly elevated alanine transaminase (ALT) level (315 U/L).Mild ALT abnormalities (48.5-88.1 U/L) were found in 3 patients with grade 3 acneiform eruptions,1 with grade 2 acneiform eruptions,1 with grade 1 acneiform eruptions and 1 with eczematoid eruptions complicated by fever.Two patients with eczematoid eruptions and 1 with morbilliform rashes showed elevated proportions of peripheral blood eosinophils (0.057-0.303).Pathological changes of the acneiform eruptions included hyperkeratosis and dilation of hair follicles and neutrophilic infiltration.Pathological manifestations of eczematoid eruptions included different degrees of spongiosis,thickened spinous layer,irregular elongation of rete ridges and liquefaction degeneration of basal cells in the epidermis,and perivascular infiltration of lymphocytes and eosinophils in the superficial dermis.Patients with grade 1-3 acneiform eruptions received oral minocycline for 6 weeks,skin lesions gradually regressed,but relapse occurred after the withdrawal.After withdrawal of targeted antineoplastic agents and 2-week treatment with systemic glucocorticoids,skin lesions gradually regressed in patients with grade 4 acneiform eruptions,those with eczematoid eruptions complicated by fever,and those with morbilliform rashes.Skin rashes also resolved in patients with mild morbilliform rashes and those with mild eczematoid eruptions after 2 weeks of treatment with antianaphylactic agents and topical glucocorticoids.Oral antibiotics were effective for the treatment of periungual erythematous swelling or granulomas.Conclusion Tyrosine kinase inhibitor-related cutaneous adverse reactions include a constellation of disorders,and hepatic function can be impaired.

OBJECTIVE: To build up a steady and credible animal model on obstructive sleep apnea-hypopnea syndrome (OSAHS) with New Zealand rabbit. METHOD: Ten New Zealand rabbit were divided into two groups (A and B, 5 for each). Group A was treated by injecting Dimethiconum from exterior. Group B was blank. EEG, snoring and oxygen-saturation were recorded by PSG after operation. Examination was repeated two weeks later and one month later. CT was done in the operation and two weeks later. Animals were sacrificed three months later and the Dimethiconum in the body was used for examination with light microscopy. RESULT: Group A showed apnea or hypopnea and decreasing SaO2 after operation. The changes in group A were more obvious at two weeks and one month. CONCLUSION A steady and credible animal model of OSAHS has been built. The model provides a tool to study the pathogenesy and pathophysiology of OSAHS.

OBJECTIVETo describe trends of changes in blood lead levels in children aged 1 - 6 years during the time period before and after introducing lead free gasoline in Shanghai 1997 and 1999.

METHODSBlood lead levels of 1 969 children aged 1 - 6 years were determined by a sampling survey in five districts of Shanghai in August and September, 1997. Blood lead levels of the same population were re-determined by the same method from April to June in 1998 and from August to September in 1999. Filter paper blood lead test was carried out monthly using the filter paper blood lead proficiency testing program of Centers for Disease Control in the United States. The results from blood lead samples were under acceptable ranges during the study.

RESULTSThe geometric means of blood lead levels were 83 microgram/L in 1997, 80 microgram/L in 1998 and 76 microgram/L in 1999, respectively. The prevalence rates of childhood lead poisoning (blood lead level was equal or more than 100 microgram/L) were 37.8% in 1997, 25.7% in 1998 and 24.8% in 1999. The amounts of decrease on average blood lead levels in the five districts between 1997 and 1999 were 10 microgram/L, 11 microgram/L, 6 microgram/L, 4 microgram/L and 2 microgram/L, respectively.

CONCLUSIONLead poisoning is a preventable disease. The average levels of lead in young children in Shanghai decreased significantly after the introduction of lead free gasoline to Shanghai. Lead emissions from vehicles running on leaded gasoline was one of the important contributors to increase the children's blood lead levels in Shanghai. Lead poisoning is not evenly distributed among children in Shanghai, resulting in the different levels of decline.
