Recently,a large family of G-protein coupled receptors (GPCRs) has been identified as mas-related genes (Mrgs),Which are specific expressed in small diameter sensory neurons in the trigeminal and dorsal root ganglia,suggesting a role in pain transmission.Mrgs receptors have been shown to modulate some physiological and pathological activities,such as pain and immunity.It is important to discover ligands of Mrgs for understanding and elucidating their potential physiological and pathophysiological roles.The studies on pharmacological spectrum of NPS make it an interesting target for pharmaceutical development.

OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.

METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.

RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.

CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.

OBJECTIVE: To analyze the case characteristics of poisoning by exhaust gas of the imperfect combustion of natural gas and provide references for forensic identification and prevention of such accidents. METHODS: Twenty-two cases of poisoning by exhaust gas of the imperfect combustion of natural gas in Minhang District during 2004 to 2013 were collected. Some aspects such as general conditions of deaths, incidence time, weather, field investigation, and autopsy were retrospectively analyzed. RESULTS: In the 22 cases, there were 15 males and 16 females. The age range was between 2 and 82 years old. The major occurring time was in January or February (8 cases in each) and the cases almost occurred in small area room (21 cases). There was wide crack next to the exhaust port when the gas water heater was been used in all cases. CONCLUSION There are more prone to occurrence of exhaust gas poisoning of imperfect combustion of natural gas in small area room with a ventilation window near the exhaust port of gas water heated. It shows that the scene of combustion exhaust gas poisoning should be more concerned in the cold season.
