To evaluate the value of silicone intubation and ring-fixed method in canalicular laceration.
●METHODS: A retrospective study of 36 cases with laceration of lacrimal canaliculus. For all the patients, microscope was used to find the broken ends of the lacrimal canaliculus, and then straight insertion was performed to the distant and near broken ends through the upper and lower lacrimal points, then passed the dacryocyst to insert nasolacrimal canal and ended up in inferior nasal meatus. Thus, clinical data about forming annular support to treat laceration of lacrimal canaliculus was presented here.
● RESULTS: All 36 patients with traumatic canalicular laceration were anastomosed successfully and all patients healed without infection. The surgery went well, intubation was smoothly, all patients were followed - up for another 6mo after the stent was removed. The accidental fall off of the stent was not observed during the follow - up. During the follow - up 10 - 18mo after extubation, when the stent was removed, 32 cases (88. 9%) recovered to normal lacrimal drainage function;4 cases ( 11. 1%) remained epiphora with obstructed lacrimal passage. All cases were no lower eyelid ectropion.
●CONCLUSlON: For the patients with inferior canalicular laceration, the silicone intubation and ring-fixed method is effective, low irritation and less complication.

ObjectiveTo observe the prepulse inhibition(PPI) ot the startle reflex of pure cerebral concussion (PCC) suffered from one concussion and multiple cerebral concussion (MCC) suffered from three concussions in rats,and to explore accumulate effect upon cognitive dysfunction of MCC.MethodsA metallic pendulum striker device for closed head injury was employed to duplicate PCC and MCC models in Stragu-Dawley rats.The MCC rats were hit three times on rats'head and it is interval 24 hours for every hit.According to the criteria of cerebral concussion,the investigated animals were divided into PCC group and MCC group at freedom.One control group was used.Each group included 10 animals.Each experience mental animal was tested from 3 days pre-injury to 28 days post-concussion.Startle reflex amplitude (for P values),pre-stimulation induced reflex amplitude on three standard stimulations,that was,67dB,69dB and 73dB (for PP67,PP69 and PP73 values) and prepulse inhibition of the startle reflex (PPI) were collected.ResultsThe P values and three PP values in the first three days of pre-replication experiment,there was no statistical significance in each group.However the P values and PP67,PP69 and PP73 values declined until to the 16th day after injury (P＜0.05),then recovered in PCC group.The P value and PP67,PP69 and PP73 values changes of MCC group declined and not recovered until to test end (P＜0.05 ) and they were more lower than PCC.The three PPI values were a little bit increase in both groups,there were statistics significance at some test points (P＜0.05) compared with control.ConclusionThe startle reflex amplitude and pre-stimulation induced reflex amplitude weaken after cerebral concussion and there is damaging accumulate effect to injury times,the PPI is enlanced by cerebral concussion.

Organic solvent tolerant microorganism(OSTM) is a novel extremophile and it hasn't been systematically studied until 1980s.Relying on certain mechanisms,the OSTM is able to effectively de-fend and decrease the toxicity from organic solvents,which enable the OSTM to be potentially applied in the industrial fields such as whole-cell catalysis and environmental treatment,etc.The comprehen-sively understanding of the mechanisms involved in organic solvent tolerance of OSTM could be com-bined with genetic engineering in order to modify and optimize the various specifications of OSTM,and further broaden its application in other industrial areas.Latest studies on the tolerant mechanisms of OSTM,in this paper,will be reviewed from four aspects such as vesicle exocytosis and changes of phos-pholipid composition in membrane,etc.Besides,the application of OSTM in whole-cell catalysis and other fields will be introduced.

OBJECTIVETo observe the effects of different therapeutic methods and the recipes of Chinese medicine (CM) on the activation of c-Jun N-terminal kinase (JNK) in Kupffer cells of rats with fatty liver disease and to explore the mechanisms of these therapeutic methods.

METHODSBy using a random number table, 98 rats were randomly divided into 7 groups: control group, model group, and 5 treatment groups, including soothing Liver (Gan) recipe group, invigorating Spleen (Pi) recipe group, dispelling dampness recipe group, promoting blood recipe group, and complex recipe group. Rats in the control group were fed with normal food and distilled water by gastric perfusion, while rats in the model group were fed with high-fat food and distilled spirits by gastric perfusion. Rats in the 5 treatment groups were fed with high-fat food and corresponding recipes by gastric perfusion. Twelve weeks later, all rats were sacrificed and liver tissues were stained for pathohistological observation. Kupffer cells were isolated from livers of rats to evaluate JNK and phospho-JNK expressions by Western blotting.

RESULTSThe grade of hepatic steatosis was higher in the model group than the control group (P<0.05). Compared with the model group, the grade of fatty degeneration in soothing Liver recipe group and invigorating Spleen recipe group were significantly ameliorated (P<0.05). Expressions of JNK and phospho-JNK in Kupffer cells were significantly higher in the model group than those in the control group (P<0.05, P<0.01). Compared with the model group, expressions of JNK in all treatment groups decreased, especially in invigorating Spleen recipe group and promoting blood recipe group (P<0.05). Compared with the model group, expressions of phospho-JNK in all treatment groups declined significantly (P<0.01), especially in soothing Live recipe group and invigorating Spleen recipe group.

CONCLUSIONSThe high expressions of JNK and phospho-JNK in Kupffer cells might play an important role in the pathogenesis of fatty liver disease in rats. The recipes of CM, especially invigorating Spleen recipe and soothing Liver recipe, might protect liver against injury by reducing the total JNK protein content and inhibiting the activation of JNK protein in Kupffer cells of fatty liver model rats, which showed beneficial effects on fatty liver disease.

AIMTo ascertain the bioactivity and to analyse quantificationally the denervating action of botulinum toxin A (BTXA) in gel.

METHODS36 Sprague-Dawley rats were randomized into four groups. In group A - D, the gastrocnemius muscle of one leg was randomly selected to receive injection of BTXA solution 5U in 0.1 ml, BTXA gel 12.5U in 0.1 ml, BTXA gel 5U in 0.1 ml and BTXA gel 2U in 0.1 ml respectively, while the gastrocnemius muscle of other leg was injected with 0.1 ml of saline solution in group A and 0.1 ml of gel in group B to group D as control. Compound muscle action potential (CMAP) of both gastrocnemius muscles were measured and the amplitudes were recorded before injections, and 5 days, 2 weeks, 3 weeks, 1 month, 2 months and 3 months after the injections respectively.

RESULTSThe reduction of CMAP amplitude was significantly different at various time (P < 0.01), and CMAP amplitude decreased significantly after the treatment of BTXA (P < 0.01). The reduction of CMAP amplitude was significantly dif ferent in group A to I) (P < 0.01), and more reduction was found in group A and B (P < 0.01), and the reduction was higher in group C than in group D (P < 0.05). However, there were no significant differences in the reduction of CMAP amplitude between group A and group B.

CONCLUSIONBioactivity of BTXA in gel was showed and the denervating action of BTXA in gel was demonstrated in a dosage and time dependent manner.

Objective: : The present study aimed to investigate the clinical characteristics of electrolyte imbalance in patients with moderate to severe traumatic brain injury (TBI) who underwent craniotomy and its influence on prognosis. Methods: : A total of 156 patients with moderate to severe TBI were prospectively collected from June 2019 to June 2021. All patients underwent craniotomy and intracranial pressure (ICP) monitoring. We aimed to explore the clinical characteristics of electrolyte disturbance and to analyze the influence of electrolyte disturbance on prognosis. Results: : A total of 156 patients with moderate and severe TBI were included. There were 57 cases of hypernatremia, accounting for 36.538%, with the average level of 155.788±7.686 mmol/L, which occurred 2.2±0.3 days after injury. There were 25 cases of hyponatremia, accounting for 16.026%, with the average level of 131.204±3.708 mmol/L, which occurred 10.2±3.3 days after injury. There were three cases of hyperkalemia, accounting for 1.923%, with the average level of 7.140±1.297 mmol/L, which occurred 5.3±0.2 days after injury. There were 75 cases of hypokalemia, accounting for 48.077%, with the average level of 3.071±0.302 mmol/L, which occurred 1.8±0.6 days after injury. There were 105 cases of hypocalcemia, accounting for 67.308%, with the average level of 1.846±0.104 mmol/L, which occurred 1.6±0.2 days after injury. There were 17 cases of hypermagnesemia, accounting for 10.897%, with the average level of 1.213±0.426 mmol/L, which occurred 1.8±0.5 days after injury. There were 99 cases of hypomagnesemia, accounting for 63.462%, with the average level of 0.652±0.061 mmol/L, which occurred 1.3±0.4 days after injury. Univariate regression analysis revealed that age, Glasgow coma scale (GCS) score at admission, pupil changes, ICP, hypernatremia, hypocalcemia, hypernatremia combined with hypocalcemia, epilepsy, cerebral infarction, severe hypoproteinemia were statistically abnormal (p<0.05), while gender, hyponatremia, potassium, magnesium, intracranial infection, pneumonia, allogeneic blood transfusion, hypertension, diabetes, abnormal liver function, and abnormal renal function were not statistically significant (p>0.05). After adjusting gender, age, GCS, pupil changes, ICP, epilepsy, cerebral infarction, severe hypoproteinemia, multivariate logistic regression analysis revealed that hypernatremia or hypocalcemia was not statistically significant, while hypernatremia combined with hypocalcemia was statistically significant (p<0.05). Conclusion : The incidence of hypocalcemia was the highest, followed by hypomagnesemia, hypokalemia, hypernatremia, hyponatremia and hypermagnesemia. Hypocalcemia, hypomagnesemia, and hypokalemia generally occurred in the early post-TBI period, hypernatremia occurred in the peak period of ICP, and hyponatremia mostly occurred in the late period after decreased ICP. Hypernatremia combined with hypocalcemia was associated with prognosis.
