Objective To clinically observe obstructive sleep apnea syndrome(OSAS) before and after cerebrovascular disease attacking and find prevention ways.Methods Seventy cases of berebrovascular patients were observed the OSAS status and the clinic data were collected in the mean time.Results We found 70% patients with snore and suffocation,89% with day drowse before attacking.After attacking,82% in-patient cases appeared different degree lower ventilation or apnea during 1～7d sleeping,which the average paroxysm frequency were 79 times per night and the average time were 72s per paroxysm.The therapeutic effects were good through different measures.Conclusion The active measures should be taken on OSAS after cerebrovascular disease attacking,which has a high frequency of OSAS.

Three cases of swimming pool granuloma are reported.Case 1:a 40-year-old female presented with a 2-month history of nodules and plaques on the right hand and forearm.She was a tropical fish salesperson but denied trauma history.Skin examination revealed multiple irregularly sized,dark-red nodules and plaques on the joints of right fingers,wrist,and elbow,as well as multiple subcutaneous nodules simulating strings of beads on the right upper limb.Case 2:a 48-year-old female presented with a 2-month history of nodules and plaques on the left hand and forearm.There was a history of trauma due to tropical fish tank and filter cleaning.Physical examination showed multiple deep purple plaques and painless subcutaneous nodules scattered on the left hand,wrist,and upper limb.Case 3:a 39-year-old male presented with a 3-month history of nodules on the fingers of both hands.There was no history of trauma,but he was a tropical aquarist.Skin examination revealed multiple soybean-sized dark-red nodules on the extensor aspect of interphalangeal joints of both hands.Fungal examinations yielded negative results in the 3 cases,while histopathology revealed infectious granuloma with a mixed inflammatory cell infiltrate.All of the cases showed positive results in purified protein derivative (PPD)skin test.Mycobacterium marinum was isolated from the lesional tissue of Case 1 and 2,but not from Case 3.All the patients were diagnosed with swimming pool granuloma,and given anti-atypical mycobacterial therapy including oral rifampin and clarithromycin.The lesions disappeared after 1 to 3 months of treatment,with the treatment course varying from 2 to 5 months.No recurrence was observed during a 3- to 12-month follow-up.

Objective To compare the clinical characteristics of normal body mass index (BMI) polycystic ovary syndrome (PCOS) patients with or without insulin resistance (IR) , and analyze the related factors of IR. Methods From January 2013 to January 2017, 128 patients with normal BMI (18.5-23.9 kg/m2) PCOS patients were divided into A group (56 cases with IR) and B group (72 cases without IR) according to whether they had IR. The clinical indicators, sex hormones, glucose and lipid metabolism indexes of the two groups were statistically compared, and the related factors influencing insulin resistance index (HOMA-IR) were analyzed by Pearson. Results Compared with B group, the waist-to-hip ratio (0.91 ± 0.08 vs. 0.80 ± 0.07), Ferriman-Gallway scores [(4.87 ± 1.66) scores vs. (3.31 ± 1.29) scores], fasting blood glucose (FPG) [(5.19 ± 0.60) mmol/L vs. (4.77 ± 0.56) mmol/L], fasting insulin (FINS) [(17.89 ± 5.85) mU/L vs. (9.83 ± 3.87) mU/L], total cholesterol (TC)[(5.03 ± 1.42) mmol/L vs. (4.52 ± 0.62) mmol/L], triglyceride (TG)[(1.72 ± 1.05) mmol/L vs. (0.98 ± 0.26) mmol/L], low density lipoprotein cholesterol (LDL-C) [(3.10 ± 1.19) mmol/L vs. (2.55 ± 0.82) mmol/L] in A group were significantly increased, while high density lipoprotein cholesterol (HDL-C) [(1.28 ± 0.30) mmol/L vs. (1.52 ± 0.23) mmol/L] significantly reduced, the differences were statistically significant (P < 0.05). HOMA-IR was positively correlated with waist-to-hip ratio (r=0.397), FPG (r=0.461), FINS (r=0.992), TC (r=0.371), TG (r=0.354) and LDL-C (r=0.478), but negatively correlated with sex hormone binding globulin (r=-0.231) and HDL-C (r=-0.299). Conclusions The waist-to-hip ratio, Ferriman-Gallway scores, glucose and lipid metabolism in normal BMI PCOS patients with IR are significantly altered. The waist-to-hip ratio, FPG, FINS, TC, TG, LDL-C, HDL-C and sex hormone binding globulin are all related factors of HOMA-IR.

OBJECTIVE To compare t he diff erences of the fingerprint and in vitro antioxidant activity between decoction pieces of Polygonum cuspidatum by integrated technology of habitat processing and processing （short for IPDP ）and traditional processing decoction pieces （short for TPDP ）. METHODS Ten batches of IPDP and ten batches of TPDP were prepared by integrated technology and traditional technology ，respectively. HPLC method was used to establish and compare the fingerprints of IPDP and TPDP. The scavenging rates of DPPH free radical ，ABTS free radical ，superoxide free radical and hydroxyl free radical and reducing activity of Fe 3+ were detected for IPDP and TPDP. In vitro antioxidant activities were compared between IPDP and TPDP. RESULTS There were 11 common peaks in the fingerprints of IPDP and TPDP ，among which 17 came from IPDP and 13 came from TPDP. The peak heights of peak 6（polydatin）and peak 15（emodin-8-O-β-D-glucoside）in IPDP were significantly higher than those in the TPDP ，and the peak heights of peak 13（resveratrol），peak 17（emodin）and peak 19（physcion）in the TPDP were significantly higher than those in the IPDP. The results of in vitro antioxidant test showed that IPDP and TPDP had a certain scavenging capacity on DPPH free radical ，ABTS free radical ，superoxide free radical and hydroxyl free radicals ，and also had a certain reducing capacity on Fe 3+. CONCLUSIONS The integrated processing technology of P. cuspidatum has a good retention effect on the glycosides in P. cuspidatum ，and the in vitro antioxidant activity of IPDP is stronger than that of TPDP.
