Persistent primitive trigeminal artery (PPTA) is the most common permanent abnormal vascular anastomosis between carotid artery and basilar artery. PPTA is a rare cerebrovascular variation and is often associated with cerebrovascular disease (CVD). Clinically, PPTA manifests itself in symptoms such as trigeminal neuralgia, oculomotor paralysis, abducens nerve paralysis, subarachnoid hemorrhage, etc. This paper aims to review 116 PPTA cases with CVD and other cerebrosis, which have ever been reported since 1983 in English or Chinese medical literature.

Objective To observe the clinical efficacy of wrist-ankle acupuncture in treating pain due to laparoscopic cholecystectomy.Method Totally 150 patients who were going to receive laparoscopic cholecystectomy were randomized into group A, group B, and group C, 50 cases in each group. Group A was intervened by wrist-ankle acupuncture prior to anesthesia, with the needles retained for 12 h; group B was by subcutaneous needling at the area nearby the points prior to anesthesia, with the needles retained for 12 h; group C didn’t receive any intervention before anesthesia. For the three groups, general inhalational and intravenous anesthesia was adopted for surgery, and patient-controlled intravenous analgesia for post-operation analgesia. The incision pain and visceral pain in the three groups were recorded by using Visual Analogue Scale (VAS) respectively 1 h, 2 h, 4 h, 8 h, 12 h, 24 h, 36 h, and 48 h after the operation. The total effective rate, analgesics consumption after operation, and incidence rate of adverse reaction were compared.Result There were significant differences in comparing the VAS scores of incision pain and visceral pain between group A and group C 4 h, 8 h, 12 h, 24 h, and 36 h after the operation (P<0.01,P<0.05). Between group A and group B, there were significant differences in comparing the VAS score of incision pain 8 h, 12 h, 24 h, and 36 h after the operation and the VAS score of visceral pain 12 h, 24 h, and 36 h after the operation (P<0.05). The total effective rate was 96.0% in group A, which was significantly different from 84.0% in group B and 86.0% in group C (P<0.05). The consumption of Fentaneyl citrate injection was (52.4±10.8)μg in group A, which was significantly different from (92.2±11.0)μg in group B and (107.2±11.5)μg in group C (P<0.05,P<0.01). The incidence rate of adverse reactions was 12.0% in group A, which was significantly different from 58.0% in group B and 66.0% in group C (P<0.01).Conclusion Wrist-ankle acupuncture plus patient-controlled intravenous analgesia can mitigate pain after laparoscopic cholecystectomy, and thus it can be taken as one of the post-operational analgesic approaches.

Objective To investigate the diagnostic accuracy of contrast-free three dimensional time-of-flight (3D-TOF-MRA) with VR at 3.0 T in the detection of intracranial aneurysms in a large cohort of patients prospectively.Methods Four hundred and eleven patients with suspected aneurysms and other cerebral vascular diseases received contrast-free 3D-TOF-MRA examinations at 3.0 T MRA 2 weeks prior to DSA examination.2D-DSA and VR-DSA were regarded as the gold standard.Six patients were excluded because of motion artifacts,and 36 patients were excluded due to lack of VR-DSA data.Accuracy,sensitivity an specificity in detecting intracranial aneurysms were determined by patient-,aneurysm-,and aneurysm sizebased (＜ 3 mm,3-5 mm,＞ 5-10 mm,＞ 10 mm) evaluations.Results In 369 enrolled patients,VR-DSA revealed 306 aneurysms in 246 patients (66.7％) and no aneurysm in 123 patients; VR 3D-TOF-MRA revealed 311 aneurysms in 249 patients and no aneurysm in 120 patients.The patient-based evaluation of VR 3 D-TOF-MRA at 3.0T yielded accuracy of 97.6％ (360/369),sensitivity of 99.2％ (242/244),and specificity of 94.4％ (118/125) in the detection of intracranial aneurysms.The aneurysm-based evaluation yielded accuracy of 98.3％ (524/533),sensitivity of 99.3％ (304/306),and specificity of 96.1％(220/229).The evaluation based on aneurysm sizes (＜ 3 mm) yielded accuracy of 96.4％ (214/222),sensitivity of 98.2％ (112/114),and specificity of 94.4％ (102/108).Conclusion VR 3D-TOF-MRA at 3.0 T MR can detect intracranial aneurysms accurately and may replace DSA as a contrast-free,noninvasive and non-radiation-based modality for the diagnosis and screening of intracranial aneurysms.

Objective To investigate the effects of gabapentin(GBP) on plasma β-endorphin(β-EP) level in the patients with painful diabetic neuropathy(PDN). Methods We detected the plasma β-EP level in 24 PDN patients in the treatment with GBP, 18 PDN patients without GBP treatment, 20 diabetic mellitus patients without PDN and 24 healthy control subjects. Results (1)The level of β-EP in diabetic mellitus patients was lower than in the healthy control(P<0.01). (2)The patients who received GBP had a significant change of β-EP level after treatment(P<0. 01).. Conclusions Gabapentin is effective for the treatment of PDN and its adverse effects are mild. It can lower the plasma β-EP level in the patients with PDN.

Most of the CHD patients reveal string pulse, mainly due to damage of heart function, lowering of arterial compliance and increase of total peripheral resistance. The common pulse in patients of blood diseases reveal frequent, tiny, string and slippery characteristic, mostly due to the increase of compensatory pumping action of the heart, shortening of ejection time of the left heart, with better vessel compliance and hemorheology, low total peripheral resistance.

OBJECTIVETo explore the incidence and genotypes of glucose-6-phosphate dehydrogenase (G6PD) gene mutations among infertile patients in Shenzhen.

METHODSDNA samples from 851 infertile patients were tested for 25 G6PD gene mutation sites using a multiplex SNaPshot assay.

RESULTSThe incidence of G6PD gene mutations among infertile patients in Shenzhen was 17.63%. Male and female abnormal rates were 15.13% and 20.09% respectively. Most of the female abnormal cases were heterozygotes. Mutations involved 11 haplotypes in 10 sites. 1311C> T/IVS-11 93T> C was the most common mutation, accounting for 72.00% (108/150) abnormal cases. Forty three cases of missense mutations were detected, including 19 cases of 1376G> T, 9 cases of 1388G> A, 5 cases of 95A> G and 871G> A/1311C> T/IVS-11 93T> C, 1 case of 202G> A, 835A> T, 1360C> T, 1376G> T and 392G> T/1311C> T/IVS-11 93T> C.

CONCLUSIONThe incidence of G6PD gene mutations among infertile patients in Shenzhen was high and the mutation types were various. Therefore, the G6PD deficiency genetic screening should be performed prior to assisted reproduction. This investigated results provided valuable basic data for genetic counseling, preimplantation genetic diagnosis and prenatal diagnosis.

Objective To evaluate the efficacy and safety of domestic palonosetron hydrochlo-ride injection on its prevention of postoperative nausea and vomiting.Methods A multi-centered,ran-domized,double-blinded and placebo-controlled clinical trial was carried out.A total of 281 patients were enrolled,with 141 of patients in study group and 140 of patients in control group respectively. 0.075 mg of intravenous palonosetron hydrochloride injection was delivered in the study group before anesthesia induction.The drug was substituted by 1.5 ml of NS in the control group.All anesthesia inductions were conducted by the intravenous injection of propofol,fentanyl and rocuronium,and were maintained with sevoflurane and fentanyl.Complete remission rate and treatment failure cut-off time of vomiting were evaluated at 0-6 h,6-72 h,0-72 h postoperatively.Results In the study group CR% 0-6 h,6-72 h and 0-72 h were 107 (75.89%),104 (73.76%)and 92 (65.25%),the control group was 81 (57.86%),70 (50%)and 62 (42.86%),CR% of the study group was significantly higher than that of the control group (P <0.01).Insignificant statistical difference but significant clin-ical difference exists in their treatment failure cut-off time,386.5 min and 300.0 min,respectively be-tween the groups.Conclusion Domestic palonosetron hydrochloride injection is safe and effective in the prevention of postoperative nausea and vomiting.

To improve the blast resistance of elite rice restorer line Fuhui 673, 3 blast resistance genes Pi-1, Pi-9 and Pi-kh were introduced into Fuhui 673 from a good-quality restorer line Jinhui 1059 through 3 successive backcrosses followed by one selfing using the technique of marker-assisted selection. Ten near-isogenic lines (NILs) of Fuhui 673 carrying the 3 introduced resistance genes were created. Genotype analysis using 68 SSR markers evenly distributed in the genome indicated that 92.96%-98.59% of the NILs' genetic background had been recovered to Fuhui 673. Both indoor and field resistance tests indicated that the NILs and their hybrids with sterile line Yixiang A were all resistant to rice blast, with resistance levels significantly higher than those of controls Fuhui 673 and hybrid Yiyou 673 (Yixiang A  Fuhui 673). In addition, among the 10 hybrids between the NILs and Yixiang A, 2 showed significantly higher yield than and 4 displayed similar yield to that of control Yiyou 673, suggesting that most of the NILs retained the elite characteristics of Fuhui 673. Two new hybrid rice cultivars Liangyou 7283 and Jintaiyou 683 from NIL Line 9 showed high yield, good resistance to blast and moderate growth period in regional trial, suggesting that the NIL Line 9 has a good prospect for application.
