The main nutrient compositions of dry Porphyra haitanensis cultivated in Lianjiang,Fujian Province were analyzed: the total amino acids content was 35.48%. The scores of amino acids were 71 for Ile and 80 for Leu. Crude fatty acids was as low as 0. 5%,in which EPA took 24.8%. Minerals in Porphyra haitanensis were abundant. The content of Ca、Fe、 Zn、Mg were 3. 63、0. 56、0. 095 and 3. 29mg?g～-1. The results indicated that Porphyra haitanensis is a kind of health food with high nutrition.

Objective Anatomical researches of two long superiror genicular vessels,the descending branch of lateral circumflex femoral artery (LCFA) and the descending genicular artery(DGA),were performed to discuss the feasibility of reconstruction in lower leg's destruction injury by free flaps transplant anastomoses with these two long superior genicular vessels.Methods Thirty embalmed lower limb specimens from adult cadavers perfused with red latex were used for this anatomical study.The superior of patella,anterior inferior iliac spine and adductor tubercle were used as observation landmark.Dissection started along the line that from the middle point of Inguinal Ligament to the middle point of superior line of patella,and dividedly turned over to posterior lateral part and posterior medial part.The followings were focused observed:①The external diameter at the beginning of the D-LCFA ; the 0.5 mm external diameter point of this artery,and its length to the beginning and superior of patella.②The external diameter at the beginning of DGA,the distance between the beginning of DGA and adductor tubercle.③Anastomoses relations of final branches of D-LCFA and DGA with other arteries around the knee.Results The external diameter of the beginning of D-LCFA was (2.73 ± 0.35) mm ; the 0.5 mm external diameter point of this artery's length to the beginning and to the superior of patella were (24.56 ± 0.92) cm and (6.09 ± 0.86) cm; both D-LCFA and DGA had sent out many perforator arteries on their ways; the final branch of D-LCFA and DGA had lots of anastomoses relations in perioseal deep fascia and superficial fascia with other genicular arteries.Conclusion Base on the anatomical researches,in theory,the two long superior genicular vessels (D-LCFA and DGA) have enough lengthes and blood supply to regress and anastomosis with free flaps transplant to repair lower leg's smashed wound.

Objectives To explore the effect of transient continuous subcutaneous insulin infusion (CSII) on β cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetic patients and its potential mechanism. Methods Ten patients with newly diagnosed type 2 diabetes mellitus (T2DM) accepted CSII for two weeks. Intravenous glucose tolerance test (IVGTT) and hyperinsulinemia euglycemia clamp test were performed before and after CSII. Serum soluble E-selectin (sE-selectin) was used to evaluate the injury of vascular endothelial cell, while serum high sensitivity C reactive protein (hsCRP) and soluble CD_(14) (sCD_(14)) were both used to assess inflammatory condition. Results (1) Compared with those before treatment, the blood glucose levels of IVGTT, the area under the curve of the blood glucose, glycosylated hemoglobin, TC and LDL-C in the patients were decreased after CSII (P < 0. 05 or 0. 01). (2) Compared with those before treatment, the insulin levels of IVGTT (except the fasting insulin), the area under the curve of insulin and acute insulin response were all increased after CSII(P < 0.05 or 0.01). (3) Compared with that before treatment, the glucose infusion ratio in the clamp test [(3.46±1.66)mg·kg~(-1)·min~(-1) increased to (7.14±2.37)mg·kg~(-1)·min~(-1)]and HOMA-β elevated, while HOMA-IR declined (P <0. 05 or 0. 01 in all). (4) Compared with those before treatment, the levels of serum sE-selectin, sCD_(14) and hsCRP were decreased (P < 0. 01, except for hsCRP) . Conclusion Transient intensive insulin therapy in patients with newly diagnosed T2DM is useful to restore 13 cell function, attenuate insulin resistance, repair vascular endothelial injury and improve the disorder of blood sugar and lipid. The mechanism may be related with the inhibition of inflammation in patients.

OBJECTIVETo compare the effects for tooth extraction between acupuncture anesthesia and drug local block anesthesia.

METHODSSixty patients were randomly assigned into an acupuncture group and a drug group, 30 cases in each one. Acupuncture was applied at Hegu (LI 4), Neiting (ST 44) and the affected side Xiaguan (ST 7), and Jiache (ST 6), etc. Arrachement was used afterand the needles were retained for 10 min after tooth extraction in the acupuncture group. Compound articaine hydrochloride injection was used to conventional local anesthesia, after which tooth extraction was implemented in the drug group. The effects of anesthesia and analgesia were compared between the two groups with pain rating index (PRI) and visual analogue scale (VAS). Besides, the bleeding amounts and adverse reaction rates during the operation and the blood pressure, pulse, and respiration before and after operation were observed.

RESULTSTooth extraction was completed, and the excellent rates, PRI and VAS scores were not significantly different in the two groups (all>0.05). The bleeding amounts and adverse reaction rates in the acupuncture group were lower than those in the drug group (<0.01,<0.05).The blood pressure, pulse and respiratory during surgery remained normal without significance between the two groups (all>0.05).

CONCLUSIONSThe effect of acupuncture anesthesia for tooth extraction is equal to that of drug anesthesia. Its analgesia is complete with stable vital signs and less adverse reactions. It is worthy of popularizing.

Objective To evaluate the effects of different fluid therapy protocols on postoperative nausea and vomiting (PONV) in pediatric patients undergoing ambulatory surgery.Methods A total of 160 pediatric patients,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 3-7 yr,weighing 14-24 kg,with body mass index ＜30 kg/m2,undergoing elective lower abdominal ambulatory surgery,were randomized into Ⅰ and Ⅱ groups (n=80 each) using a random number table method.Lactated Ringer's solution 10 ml · kg-1 · h-1 and 30 ml · kg-1 · h-1 were intravenously infused in group Ⅰ and group Ⅱ,respectively.Ibuprofen 20 mg/kg was given orally after operation to maintain Face Legs Activity Cry Consolability score ＜4.The development of PONV and thirst and requirement for antiemetics was recorded within 24 h postoperatively.The time of first PONV,time of first thirst and score for satisfaction of family members were also recorded.Results Compared with group Ⅰ,the incidence of PONV and thirst was significantly decreased,the time of first requirement for antiemetics and time of first thirst were prolonged,and the score for satisfaction of family members was increased (P＜ 0.05),and no significant change was found in the requirement for antiemetics in group Ⅱ (P＞0.05).Conclusion Intravenously infusing fluid 30 ml · kg-1 · h-1 can decrease the occurrence of PONV when compared with intravenously infusing fluid 10 ml · kg-1 · h-1 in pediatric patients undergoing ambulatory surgery.
