Objective To explore the effect of LPLD (laparoscopic peritoneal lavage and drainage ) on SAP (severe acute pancreatitis), and to compare its effect with that of non- LPLD (conservative medical management). Methods We collected data from 87 consecutive patients with SAP, from January 2009 to May 2014, including LPLD group (n = 46) and non-LPLD group (n = 41). LPLD was performed in the 1st and 2nd week after the disease onset in LPDP group and other treatment in LPDP group was the same as that in non-LPLD group. Data were comparatively analyzed in two groups about the length of hospital stay, ICU stay, cure rate, incidence of complications and in-hospital mortality. Results In LPLD group, hospital stay, and ICU stay were shorter while cure rate was higher than those in non-LPLD group , and the difference was statistically significant (P < 0.05). In terms of the incidence of complications in two groups, only the incidence of sepsis indicated statistical significance (P < 0.05) and in-hospital mortality did not differ significantly between two groups (P > 0.05). Conclusion Compared with non-LPLD, LPLD is effective in short outcome, which is a promising treatment for SAP.

Objective To evaluate the clinical value of percutaneous transhepaticcholangioscopic lithotomy (PTCSL)combined with rigid cholangioscopy in treatment of recurrent hepatolithiasis. Methods Retrospective analysisof therapeutic result of 54 patientswith postoperative recurrent hepatolithiasisduring January 2012 to January 2015. Twenty eight cases were recruited as the observation group (PTCSL group). Twenty six cases were recruited as the control group (Laparotomy group). Following parameters were observed, operation time, intraoperative blood loss, clearance of stones and postoperative hospital stay. Results The operation time, intraoperative blood loss , clearanceof stones , and the postoperative hospital stay of the PTCSL group werebetter than that of the laparotomy group (P<0.05). The number of patients with postoperative pain of the PTCSL group was significantly lower than in the laparotomygroup (P<0.05). There were no significant differences in other complication rates. There was no difference in terms of stone recurrence , incidence of cholangitis and intrahepatic biliary strictures recurrence ratebetween two groups in follow-up period. Conclusions PTCSL combined with rigid choledochoscopywas a safe and effectivemethod with minimal invasion formanagement of the postoperative recurrent hepatolithiasis. It could got a better resultsin the short-term outcomes.

Abstract: Objective To establish an animal model of BALB/c mice infected with Burkholderia pseudomallei through the nose (inhalation route), provides a reliable animal model for the follow-up studies on the virulence of melioidosis and the pathogenesis of acute melioidosis. Methods　The experiment was carried out through infecting with Burkholderia pseudomallei through the nose (inhalation route). The pathophysiological response, visceral pathological damage and bacterial colonization of the mice infected with Burkholderia pseudomallei were observed by gross anatomy, histopathology and tissue homogenate count, and the biological characteristics of the mouse model of acute melioidosis were analyzed accordingly. Then we compared the physiological responses in BALB/c mice between the Burkholderia pseudomallei and non-pathogenic Burkholderia thailandensis. Results　In the model of acute nasal infection with Burkholderia thailandensis, most death happened between the 3rd to 5th day after infection, 3×105-3×106 CFU was the suitable dose for acute fatal melioidosis model of BALB/c mice, and the medium lethal dose was about 3×104-3×105 CFU. Both gross anatomy and tissue HE staining showed that abscesses or necrosis were found in the lung, spleen and liver, especially in the spleen and lung, which was positively correlated with the challenge dose. Viable bacteria was isolated from the blood, lung, spleen and liver of Burkholderia pseudomallei-infected mice, and the bacteria account colonization was related to tissue specificity. The concentration of live bacteria isolated from in the blood was the highest [Log2 value: (10.28±0.34) CFU/mL], and the organ with the maximum quantity of bacteria was the lung [Log2 value: (7.54±2.11) CFU/total organ]. It has been reported that the biological effects of Burkholderia pseudomallei and its homologous non-pathogenic Burkholderia thailandensis were similar at the cellular level, like multi-nuclear giant cell formation and active intracellular replication, while it is still unclarrified in the differences of virulence in mice. In this study, it was proved that Burkholderia thailandensis was not fatal to mice even at a high dose (8×107CFU), or detected from mice infected with it via nasal. Conclusion　We successfully established a reliable BALB/c mouse model (acute lethal model) of melioidosis via nasal infection, described its biological characteristics, and identified the different biological responses between Burkholderia pseudomallei and its homologous non-pathogenic Burkholderia thailandensis in mice.

Objective To identify changes in the occurrence of endemic fluorosis in order to provide scientific basis for making countermeasures. Methods Five villages from 14 counties of mild, moderate and severe fluorosis affected areas were selected by stratified cluster sampling every year in the whole province during 2006 - 2010. Water and urinary fluorine were determined by ion selective electrode method(GB/T 8538-1995); dental fluorosis of children 8-12 years old was diagnosed with Dean method; skeletal fluorosis was diagnosed according to "clinical indexing standards of endemic skeletal fluorosis "(GB 16396-1996), between 2006 and 2008, and "clinical diagnosis standard of endemic skeletal fluorosis"(WS 192-2008) between 2009 and 2010. Results A total of 25 diseased villages were surveyed, 14 with water sources changed, covered a resident population of 8005 people, beneficiary population 7154, and accounting for 89.37% of the resident population; not changed villages 11. In accordance with the "State drinking water health standards", in the 14 changed villages the fluoride in drinking water was qualified (≤ 1.20 mg/L), there were 3 schools whose water fluorine content exceeded the standard; among the 11 villages that did not change water sources 7 drinking water samples fluorine content exceeded the standard. Of the 8 to 12 years old children in villages with changed water sources, 363 of them were checked and 142 dental fluorosis were found, the detection rate of dental fluorosis was 39.12% (142/363); in villages with water sources not changed, 303 children were checked, the detection rate of dental fluorosis was 43.89%(133/303). Of sixteen and elder adults in water source changed villages, 6424 people were checked and 403 skeletal fluorosis were found, skeletal fluorosis detection rate was 6.27% (403/6424); 3572 people were checked in not changed villages, the detection rate of skeletal fluorosis was 13.89%(496/3572). In water sources changed areas, geometric mean of urinary fluoride was in the normal reference value(WS/T 256-2005, 1.40 mg/L)or less. Conclusions Endemic fluorosis is decreased in water improved areas, but in unimproved areas the disease is still severe, and control of endemic fluorosis is still an arduous task.

OBJECTIVETo explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.

METHODSFifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups.

RESULTS(1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05).

CONCLUSIONThere is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.

OBJECTIVETo evaluate the clinical efficacy of mini-open repair for the treatment of acute closed achilles tendon ruptures.

METHODSFrom April 2012 and October 2013,14 patients (14 feet) with acute closed achilles tendon ruptures were treated in our department. They were 9 males and 5 females, with an average age of 30.5 years old (ranged, 25 to 49 years old). The interval between injury and operation ranged from 1 to 13 days (8 days on average). A longitudinal incision approximately 1.5 to 2.0 cm in length was made around the ruptured achilles tendon for mini-open repair after insertion of oval clamp. Postoperative rehabilitation was carried out.

RESULTSThe wounds healed at the first stage except 2 cases with slow recovery. All the patients were followed up for 6 to 24 months, with an average of 11 months. According to the ankle-hindfoot scoring system of American Orthopaedic Foot & Ankle Society (AOFAS),the score was 92.71 ± 6.58 (82 to 100).

CONCLUSIONThe surgical treatment of acute achilles tendon rupture with mini-open repair has advantages of little invasion, a low rate of incision problems, quick function recovery, and simple operation, and it is suitable for primary hospital.

OBJECTIVETo explore the mechanism of rehabilitation after middle cerebral artery occlusion (MCAO).

METHODSMCAO model was reproduced with two-kidney, two clip renovascular hypertensive rats stroke-prone (RHRSP), which were divided into two groups, the treated group (treated with electric stimulus) and the control group (untreated model) randomly. The rehabilitation of rats was evaluated by balance beam walking test. The ultrastructural changes of neurons and astrocytes, expressions of glial fibrillary acidic protein (GFAP)-positive cells, neurofilament (NF) protein, and cerebral capillary dilatation M-associated protein-2 (MAP2), as well as the neurons apoptosis and the number of dilatation of cerebral capillary in the margin of infarcted area were observed by the end of 1st, 3rd, 6th and 9th week after modeling.

RESULTSThe motor function of paralysed limbs recovered better in the treated group than that in the control group by the end of 3-9th week after MCAO, the expression of GFAP-positive cells in astrocytes and NF, MAP2 in neurons as well as the number of cerebral capillary dilatation at the margin of infarcted area were higher than those in the control group (P < 0.05).

CONCLUSIONElectric stimulation treatment could improve the recovery of motor function of paralyzed limbs. It might be due to the effect of electric stimulus in increasing astrocytes proliferation, reinforcing activity of neurons and evoking the dilatation of cerebral capillary.
