Objective To investigate the optimum ratio of medicine dosage for dexmedetomidine mixed with oxycodone used for patient-controlled intravenous analgesia (PCIA) after gastrointestinal surgery.Methods Eighty patients of both sexes, aged 35-64 yr, weighing 55-75 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective gastrointestinal surgery, were randomly divided into 4 groups (n=20 each) using a random number table: oxycodone group (group O), and different ratios of medicine dosage when dexmedetomidine was added to sufentanil groups (OD1-3 groups).At 15 min before the end of surgery, oxycodone 0.1 mg/kg was injected intravenously, and PCIA pump was connected simultaneously.In group O, the PCIA solution contained oxycodone 1.00 mg/kg in 100 ml of normal saline.In group OD1, the PCIA solution contained oxycodone 1.00 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.In group OD2 , the PCIA solution contained oxycodone 0.75 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.In group OD3, the PCIA solution contained oxycodone 0.50 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.The PCIA pump was set up to deliver a 0.5 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Oxycodone 0.05 mg/kg was injected intravenously as a rescue analgesic, and visual analogue scale score was maintained ≤ 4.The requirement for rescue analgesics was recorded.The requirement for the rescue analgesic was recorded within 48 h after surgery.The number of successfully delivered doses, and occurrence of adverse reactions such as bradyeardia, hypotension, nausea, vomiting, over-sedation, somnolence, pruritus, and respiratory depression were recorded.Patient's satisfaction with analgesia was recorded at 72 h after surgery.Results No patients required the rescue analgesic or developed over-sedation, vomiting, respiratory depression and hypotension in the four groups.Compared with group O, the incidence of somnolence was significantly increased in group OD1, the incidence of nausea, somnolence, bradycardia and pruritus was decreased in OD2 and OD3 groups, and the degree of patient's satisfaction with analgesia was increased in OD1-3 groups (P＜0.05).Compared with group OD1, the incidence of nausea, somnolence, bradycardia and pruritus was significantly decreased in OD2 and OD3 groups, the degree of patient's satisfaction with analgesia was increased in group OD3 (P＜0.05) , and no significant was found in the degree of patient's satisfaction with analgesia in group OD2 (P＞0.05).Compared with group OD2, no significant was found in the incidence of adverse reactions (P＞0.05) , and the degree of patient's satisfaction with analgesia was significantly decreased in group OD3 (P＜0.05).The number of successfully delivered doses was significantly larger in group OD3 than in O, OD1 and OD2 groups (P＜0.05).Conclusion Dexmedetomidine 2.5 μg/kg added to oxycodone 0.75 mg/kg is the optimum ratio of medicine dosage when used for PCIA after gastrointestinal surgery.

OBJECTIVETo observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.

METHODSA total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.

RESULTSThe total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).

CONCLUSIONCDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.

Objective To summarize the characteristics of acupoints selection in acupuncture-moxibustion treatment of primary dysmenorrhea (PD) based on data mining. Method Clinical literatures published in the recent 10 years related to acupuncture-moxibustion treatment of PD were collected to establish a prescription database by using Excel. The descriptive analysis, association rules analysis and clustering analysis were conducted by Python and Clementine12.0. Result A total of 74 acupoints were involved with a total frequency of 1072. The leading three meridians were Spleen Meridian (325 times), Conception Vessel (260 times) and Bladder Meridian (158 times); the leading acupoints were Sanyinjiao (SP6, 174 times), Guanyuan (CV4, 111 times), Diji (SP8, 79 times), Ciliao (BL32, 73 times) and Qihai (CV6, 67 times). The utilization of the specific acupoints accounted for 66.22% (49/74). The crossing acupoints were predominant (393 times), especially Sanyinjiao, Guanyuan and Zhongji (CV3), followed by the five-Shu points (195 times), Front-Mu points (195 times) and Yuan-Primary points (99 times). The association rules analysis showed that Guanyuan and Sanyinjiao had the most significant correlation. The clustering analysis figured out 8 core clustering groups. Conclusion The characteristics of acupoints selection revealed in this study provide ideas and references for acupuncture-moxibustion treatment of PD in clinic.

OBJECTIVETo observe the clinical efficacy of Tiaozhi Jiangtang Tablet (TZJT) on patients suffering from diabetes mellitus with blood stasis syndrome.

METHODSSixty patients were randomly assigned into 2 groups, the TZJT group (n = 30) treated with TZJT tablet and asprin, the control group (n = 30) treated with asprin alone.

RESULTSThe improvement of symptoms was more significant in the TZJT group than that in the control group (P < 0.05). Levels of serum endothelin (ET), nitric oxide (NO) content and blood viscosity were decreased in both groups after treatment, and the effect of TZJT plus asprin was superior to that of asprin alone.

CONCLUSIONTZJT combined with asprin is effective in improving the serum content of ET and NO and reducing blood viscosity.

OBJECTIVETo study the correlation between brainstem auditory evoked potential (BAEP) and serum neuron-specific enolase (NSE) in neonates with asphyxia and explore the role of NSE in the evaluation of hearing impairment following asphyxia.

METHODSFifty-two term neonates with asphyxia, including 38 cases of simple asphyxia (mild: 23 cases; severe: 15 cases) and 14 cases of asphyxia complicated by hypoxic-ischemic encephalopathy (HIE), were enrolled. In the double-blind trial, BAEP and NSE were simultaneously detected 7 days after birth. The patients who did not pass BAEP test received another BAEP and NSE examinations 3 months after birth. Thirty healthy term neonates served as normal control group.

RESULTSOf the 52 neonates with asphyxia, 50.0% and 21.2% of patients failed the initial and the second BAEP tests, respectively. The detection rates of BAEP anomalies in the simple severe asphyxia group in the initial and the second tests (63.3% and 26.3%, respectively) were significantly higher than those in the simple mild asphyxia group (36.9% and 5.9%, respectively)(P<0.05). The neonates with asphyxia complicated by HIE showed a higher detection rate of BAEP anomalies in the second test compared with the asphyxiated neonates without HIE (31.3% vs 16.7%; P<0.05). Mean serum NSE levels in asphyxiated neonates were significantly higher than those in normal controls (<0.01). There were significant differences in serum NSE levels between the neonates with mild and severe asphyxia (26.70+/-2.34 microg/L vs 17.18+/-3.16 microg/L; P<0.01). The asphyxiated neonates with HIE had serum NSE levels similar to the simple severely asphyxiated neonates. Serum NSE levels in patients who failed the initial BAEP test were significantly higher than those who passed the test (25.69+/-4.12 microg/L vs 17.15+/-3.09 microg/L; <0.01). Serum NSE levels had a positive correlation with wave V reaction threshold detected in the BAFP test (<0.05).

CONCLUSIONSThe serum level of NSE is closely correlated with BAEP, and it may be useful to the evaluation of the hearing impairment and the outcome in neonates with asphyxia.

OBJECTIVETo study the effect of dragon's blood powder with different grain size on the transdermal permeability and adhesion of ZJHX paste.

METHODDragon's blood powder with grain sizes of 4, 19, 55 microm were got by ultrafine grinding technology, and then prepared into rubber pastes A, B, C and D, together with dragon's blood powder with grain size of 93 microm of original description. Franz diffusion cell method was adopted to compare the difference in transdermal permeability of dragon's blood powder with different grain sizes, with dracorhodin as the index, and compared their effect on the adhesion of pastes with initial adhesion, permanent adhesion and peel strength as the indexes.

RESULTQ(s)-t equations of pastes A, B, C, D were as follows: Q(s)=1.369 6t + 3.985 5, Q(s) = 1.262 8t +3.738 1, Q(s) = 1.192 3t + 3.320 6, Q(s) = 1.152 2t + 2.366 1, respectively, which showed that the adhesion of A was the best good.

CONCLUSIONWith the decrease in the grain size of dragon's blood powder, accumulative penetration of dracorhodin increases, which facilitates transdermal permeability and adhesion.

OBJECTIVETo assess the morphologic changes in traumatic cerebral infarction and to discuss its mechanism.

METHODSSpecimens from seventeen cases of cerebral infarction were selected from 81 patients with severe brain injury, and subject to routine gross and histological examinations.

RESULTS(1) The cerebral infarction in all cases was hemorrhagic in nature with a wedged or irregular shape upon gross inspection. The lesions were found in occipital gyrus (8 cases), occipital lobes (3 cases), basal nuclei (3 cases), cingulate gyrus (2 cases), and lateral occipitotemporal gyrus (1 case). Histologically, the lesions were located at the junction between the cortex and medulla, showing congestion, edema, hemorrhage, necrotic nerve tissue and blood vessels. In severe cases, the lesion extended into the entire cortex and subarachnoid spaces. (2) Swelling of the brain and cerebral hernia were found in all cases, 8 of which demonstrated that the posterior cerebral artery was compressed and stenotic within the space between the crus cerebri and uncus.

CONCLUSIONBrain tissue necrosis in traumatic cerebral infarction is the result of brain swelling and cerebral hernia formation, following congestion, bleeding and ischemia due to vasculature compression.
