BACKGROUND: It is commonly believed that hyperbaric oxygen (HBO)plays a neuroprotective role in the prevention and treatment of cerebral infarction (CI), however hyperbaric oxygen therapy (HBOT)-induced CI was also reported.OBJECTIVE: To investigate the risk factors of HBOT-induced CI.DESIGN: Case analysis with patients as subjects.SETTING: At the Department of Hyperbaric Oxygen of Guangzhou General Hospital of Guangzhou Military Command Area of Chinese PLA.PARTICIPANTS: Totally 192 inpatients receiving HBOT were selected from the Department of Hyperbaric Oxygen of Guangzhou General Hospital Guangzhou Military Command Area of Chinese PLA between December 1996 and March 1998, including 127 males and 65 females with age ranging from 9 to 78 years old. Totally 6 patients, 3 males and 3 females, suffered from CI during HBOT, with the age from 51 to 76 yeas.METHODS: The background factors of 192 patients who HBOT METHODS and 6 cases with induced CI were analyzed.MAIN OUTCOME MEASURES: Symptoms, signs and skull CT or MRI.RESULTS: Data of 192 patients were dealt with intentionally and all were statistically analyzed without miss. ① The incidence of CI during HBOT was 0.3% (6/192). ② The risk factors of HBOT-induced CI included: age of ≥ 60 years, hypertension, hyperlipidemia, primary CI or cerebral hemorrhage, blood hyperviscosity and diabetes, and the incidence would greatly increased in those who has 4 or more than 4 risk factors, but seldom with less than 4 risk factors.CONCLUSION: The cluster level of risk factors was closely related with the incidence of HBOT-induced CI.

Objective To investigate the effection of Shenfu Injection (Ginseng-radix aconitum Injection)to the blood coagulation system and its prognosis in the patient of multiple trauma complicated with shock.Methods We prospectively studied 90 patients of multiple trauma complicated with shock,who came from the emergency center of the Second Affiliated Hospital of Medicine' s college of Zhe-Jiang University and emergency department of Lishui People' s Hospital from February 2007 to December 2011,and excluded those suffered with the dysfunction of coagulation system and uncontrolled ongoing bleeding before trauma.And then these eligible patients were randomly divided into two groups:treatment group ( 45 cases ) and control group (45 cases),the control group were received the routine treatment,the treatment group were received Shenfu Injection in early stage based on the routine treatment.The two groups were measured the platelet count (PLT),prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),fibrinogen (FIB) before treatment and 3,7 days after treatment.Results The differences of the PLT,PT,APTT,TT,FIB between the treatment group and control group at 3,7 d after the treatment was statistically significant (P ＜ 0.05 ). Conclusions Shenfu Injection has positive regulation to the coagulation system in the patient of multiple trauma complicated with shock.

OBJECTIVETo study the molecular action mechanism of active constituents desoxyrhaponticin (DES) and human serum albumin (HSA).

METHODUnder the simulated physiological condition, computer analog technology, fluorescent spectrometry and ultraviolet spectrum were combined to study the binding mechanism between drug and protein.

RESULTMolecular modeling was adopted to establish the binding model between DES and HSA, suggesting that the interaction force maintaining drug and protein is mainly the hydrophobic interaction with a hydrogen-bond interaction. The results from spectroscopy indicated that the interaction between DES and HSA is a dynamic binding process with a high intensity. The value of the binding distance (r) between DES and HSA was low, which demonstrate the occurrence of energy transfer. DES made an impact on HSA' structural domain microcell conformation, which resulted in hydrophobic changes in binding areas. According to the fluorescent phase diagram technical analysis, the changes in the DES-HSA reaction conformational pattern showed a "two-state" model. According to the obtained thermodynamic parameters for the DES-HSA interaction, the interactional force between DES and HSA was mainly a hydrophobic interaction. The fluorescence polarization proved that a non-covalent compound was generated during the interaction between DES and HSA.

CONCLUSIONThe spectrum experiment showed consistent results with the computer analog technology, which could provided certain reference for studies on the interaction between DES and HSA.

The enzyme activity of ?- Acetolactate Decaroboxylases (ALDC) from different microbes was studied, the results demonstrated that it was quite different among them. There were diversities of their enzyme reaction velocities. It was clear that the enzyme activity was affected by the pH of the enzyme reaction system, for example, the optimum pH of ALDC from Lactococcus lactis was 6. 6, while for Aerobacter Aerogenes it was 5. 8. Addition leucine,valine and isoleucine into enzyme reaction system obviously affected the enzyme activity of ALDC from different microbes.

Objective To evaluate the effectiveness of the treatment of slight and moderate benign prostatic hyperplasia(BPH)with large doses of cemilton by urodynamie test.Methods A systematic review of using large doses of cernihon only for 80 patients with BPH with 7 grade ＜ International Prostate Symptom Score(IPSS)≤20 grade.All cases with cemilton had been administered in a dosage of 750 mg,three times a day for one year.All were respectively given IPSS,postvoiding residual urine(PVR),maximum flow rate(Qmax)and pressure-flow(A-G)test in order to assess the effectiveness at pre-treatment and 3,6,12 months after treatment.Results All patients had followed up for(1.2±1.6)years,additionally 26 of those were removed and others had received complete follow-up.Before the treatment IPSS was(20.5±4.5)grade,PVR was(42.5±8.2)ml,Qmax was(10.2±2.3)ml/s,A-G was 56.5±12.8,PQmax was (54.8±13.7)mm Hg(1 mm Hg = 0.133 kPa),and 12 months later,IPSS was(11.0±3.3)grade,PVR was (15.9±7.4)ml,Qmax was(15.7±2.5)ml/s,A-G was 49.2±13.6,PQmax was(43.6±14.9)mm Hg.There were significantly difference between pre-treatment and post-treatment data of the urodynamics(P ＜ 0.05).Conclusions The effectiveness of the treatment of slight and moderate benign prostatic hyperplasia with large doses of cemihon are relatively satisfactory.Main post-treatment urodynamic parameters obviously improves than that of the pre-treatment.

This paper introduces the designing process of a massaging machine on the basis of Pro/Engineer. The machine has realized the virtual design and movement simulation for the product. It's computer-controlled system has greatly improved the automatic level of the massaging machine which has broad prospects for popularization and application.

AIM: To investigate the time - effect relationship between the expression of rhodopsin and recoverin and photoreceptor damage induced by N - nethl - N -nitrosourea ( MNU) .
METHODS: Thirty-six 7-week old Sprague-Dawley ( SD ) rats were intraperitoneally injected with MNU ( 60mg/kg ) and were put to death by dislocation of cervical vertebra 6, 12, 24h; 3, 7d after injection ( 6 per group) , respectively. As a control, six rats were injected with phosphate buffer saline (PBS) 5mL/kg and sacrificed on d3 after injection. The degree of photoreceptor apoptosis was detected by HE staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling ( TUNEL ) and transmission electron microscope ( TEM ) in the right eyes. The mRNA expressions of rhodopsin and recoverin were detected different time after injection by Western blot and immunohistochemical method in the left eyes.
RESULTS:The dissolution of photoreceptor nucleus and apoptosis body were first perceived at 12h by TEM; most of cells at outer nuclear layer were presented positive reaction. The apoptotic index reached peak ( 29. 7% ±2.3%) at 24h which was coincided with the observation of TEM. The results of immunohistochemistry displayed that rhodopsin and recoverin were on a declining curve with time extension. Furthermore, the results of Western blot indicated that rhodopsin had dramatic decline at 6h after injection (P<0. 05), and extremely significant difference comparing to control group after 12h ( P<0. 01 ); while recoverin dramatic declined at 12h, and extremely significant difference after 24h (P<0. 01).
CONCLUSION:60mg/kg MNU intraperitoneally injection one - time may specifically induce photoreceptor apoptosis, The mechanism of down - regulation of rhodopsin and recoverin may be related to the selected apoptosis of photoreceptors.
