Objective To observe the clinical efficacy ofZhibai Dihuang Decoction combined with endocrine therapy for kidney-yin deficiency type of advanced prostate cancer and its influence on patient symptoms of hot flashes.Methods Totally 72 cases of advanced prostate cancer patients were randomly divided into the combined group (36 cases) and the control group (36 cases). Patients in the control group were treated with endocrine therapy, while patients in the combined group were additionally treated byZhibai Dihuang Decoction. After 12 weeks of treatment, serum prostate specific antigen (PSA), the international prostate symptom score (I-PSS), the clinical symptoms score, the number of cases of hot flashes and safety index before and after treatment were observed. Results In the course of treatment, the control group and the combined group each had 1 case lost to follow up. PSA and I-PSS in the two groups significantly decreased after treatment (P<0.01). The total efficiency rate of TCM syndrome was 94.3% (33/35) in the combined group, while it was 57.1% (20/35) in the control group, with significant difference (P<0.01). After treatment, the incidence of hot flushes was reduced after treatment in the combined group, but the control group increased, with significant difference (P<0.01). No adverse reaction was found in the two groups.ConclusionZhibai Dihuang Decoction combined with endocrine therapy is more effective than endocrine therapy alone, which can reduce the symptoms of hot flashes.

Objective To observe the clinical therapeutic effect of acupuncture combined with acupoint injection in the treatment of post -stroke intractable hiccup.Methods 120 patients with post -stroke intractable hiccup were randomly divided into treatment group(60 cases)and control groups(60 cases)according to the digital table.The patients in the control group were treated with baclofen tablets and methloxetamine hydrochloride injection, and the patients in the treatment group were treated with acupuncture combined with acupoint injection therapy.The treating period was 1 week.The scores of hiccup symptoms,the total effective rate and side effect were recorded before and after the treatment in all patients.Results The scores of hiccup symptoms before treatment in the treatment group and the control group were (5.32 ±1.17)points and (5.25 ±0.65)points respectively,there was no statistically significant difference between the two groups(t =1.79,P =0.96).The scores of hiccup symptoms on the 1 day after treatment in the treatment group and the control group were (3.97 ±1.24)points and (3.85 ±1.02 )points respectively,there was no statistically significant difference between the two groups(t =1.93,P =0.48).The scores of hiccup symptoms on the 3 days after treatment in the treatment group and the control group were (2.80 ±0.73)points and (3.75 ±1.11)points respectively,there was significant difference between the two groups(t =2.66,P =0.00), that in the treatment group was lower than the control group.The scores of hiccup symptoms on the 5 days after treatment in the treatment group and the control group were (2.25 ±1.07)points and (3.43 ±0.81)points respec-tively,there was significant difference between the two groups(t =2.85,P =0.00),that in the treatment group was lower than the control group.The scores of hiccup symptoms on the 7 days after treatment in the treatment group and the control group were (1.27 ±0.66)points and (2.02 ±0.98)points respectively,there was significant difference between the two groups(t =1.07,P =0.00),that in the treatment group was lower than the control group.The total effective rates in the treatment group and the control group were 90%(54 /60)and 65%(39 /60)respectively,there was significant difference between the two groups(χ2 =10.75,P =0.00).The incidence rates of side effects in the treatment group and the control group were 1.7%(1 /60)and 6.7%(4 /60)respectively,there was no statistically significant difference between the two groups(χ2 =0.84,P =0.36).Conclusion Acupuncture combined with acu-point injection can significantly reduce the hiccup symptom score of post -stroke intractable hiccup patients on the 3, 5 and 7 days after treatment,and improve the total effective rate.

Hyperhomocysteinemia is an important independent risk factor for cardio-cerebrovas- cular diseases.Studies in recent years have suggested that hyperhomocysteinemia is also an independent risk factor for vascular dementia and Alzheimer's disease.Mild vascular cognitive impairment is the prophase of vascular dementia.Mainly through the damage of vascular wall structure and its function,homocysteine may has correlation with mild vascular cognitive impairment.

Objective To investigate the effect of neutral amino acid on preventing Parkinson disease.Methods Mice were injected with L-Valine,L-Pheylalanine,D-Valine or L-Lysine before or after paraquat administration,by which prakinsonian mouse model was constructed.The paraquat immunoreactivity was observed within nigral cell bodies.Then neurodegeneration and ?-synuclein aggregation were observed by immunohistochemistry and Western blot.Results Paraquat immunoreactivity was abolished by the administration of L-Valine,L-Pheylalanine before paraquat exposure.Pre-treatment with these two amino acids also protected the paraquat-induced loss of nigrostriatal dopaminergic cells and formation of thioflavine S-positive aggregates.In contrast, paraquat-induced toxicity was unaffected if animals were injected with these two amino acids after paraquat exposure or pre-treated with D-Valine or L-Lysine.Conclusions L-type neutral amino acids such as L Valine and L-Pheylalanine can prevent paraquat-induced neurodegeneration and a synuclein pathology through a competitive inhibition mechanism with stereospecificity in the central nervous system (CNS).Neutral amino acid could protect the dopaminergic neuron in substantia nigra and may prevent Parkinson disease.
