Chinese Journal of Forensic Medicine 1986;0(02):-
Objective To explore the time-related expressions of TGF-?1mRNA during the healing process of rat skin wounds. Method Using the method of the reverse transcriptase polymerase chain reac-tion (RT-PCR) on intra-vital rat skin incised wounds (0.5h, 1h, 3h, 6h, 48h, 72h, 96h, 168h after incision) and postmortem rat skin incised wounds (0.5h, 1h, 3h after incision) to detect the dynamics of expression Ievel of TGF-?1mRNA. The strength of the expression of TGF-?1mRNA in scanned image was using ID-Advanced software. Results The results of RT-PCR showed that TGF-?1mRNA Ievel increased at 0.5h after incision and elevated significantly after 3h. The peak of TGF-?1mRNA occurred at 48h. There was no obvious expression of TGF-?1mRNA in postmortem incised wounds. Conclusion The characteristics of the TGF-?1mRNA expression were potentially indicative for the wound aging. RT-PCR was a sensitive method for detection of the expression of cytokines in genic level.

Objective To find a sensitive index which can reveal the mild cognitive impairment in non-demented patients with Parkinson’s disease (PD).Methods Thirty PD patients without clinical dementia and 34 age-matched normal controls performed a matching-to-sample task while event-related potential (ERP) was recorded from their scalp. There were two kinds of stimulus pairs in this study: condition 1, the second stimulus (S2) in a pair was identical to the first one (S1) (match condition); condition 2, S2 conflicted with S1 in their color attribute (conflict condition). Subjects were required to press a button in the match condition and another button in the conflict condition.Results In the match condition, P100, N150, P180, N200, and P300 were elicited by S2. In the conflict condition, potentials following N200 went continuously to negativity and formed another component,N270,before P300. The N270 component was evoked by S2 of conflict condition in both controls and patients. The patient group showed a delayed and smaller N270 than the control group[peak latency: P3,patients:(317?37) ms,controls:(298?31) ms;P4, patients: (313?35) ms,controls: (293?34) ms;amplitude: P3,patients: (-3.06?2.51) ?V,controls: (-4.55?2.86) ?V]. The peak amplitude of P300 was decreased in the patient group [P4,patients: (6.94?3.95) ?V,controls: (9.58?3.80) ?V], but the peak latency of P300 did not differ significantly between the two subject groups. There was no difference between the two groups in peak latency and amplitude of N150.Conclusion PD patients have cognitive impairment even in the absence of a clinical dementia. N270 is subtler than P300 in revealing the mild cognitive impairment.

Objective To study the expression of S100B and glial fibrillory acidic protein (GFAP) after primary brainstem injury in rat and discuss the changes with brainstern injury time and their mechanism in the injury. Methods The brainstem injury animal model was established using the mechanical impact-ing method. The HE staining, Gless argentaffin staining and SP immunohistochemical method were ap-plied to observe the changes of S100B and GFAP at different injury time. The immunostaining results were measured statistically with imaging analysis technology. Results A large number of S100B positive cells could be seen in 30 min. Afterward, expression increased gradually with time and peaked up in 24 h, and reversed back the normal in 72 h. The GFAP positive cells showed rise continually in 30 min, and reached the peak in 48 h, then started to decrease, but still higher than that in control. Conclusion The expression of S100B and GFAP is correlated with post traumatic intervals after brainstem injury in rat, and may be useful in estimation post traumatic intervals and nerve regeneration.

Objective To assess the prevalence of gastroesophageal reflux disease(GERD) in the population of Fujian province, and to analyze the risk factors in relation to the disease. Methods A survey on GERD symptoms and its related factors was carried out in the population of Fuzhou city in Fujian province using a stratified random sampling method. According to reflux disease questionnaire (RDQ) score, the subjects were divided to GERD group with Sc≥ 12 and control group with Sc< 12.The risk factors related to GERD were compared between two groups. Results A total of 1347residents were investigated. The prevalence of GERD was 8.76 %, and male to female ratio wasincreased in population above 40 years of age (P<0.05). The incidence of GERD in subjects with different occupations was as follows: the businessmen [17.91%(12/67)], retirees [13.48%(12/89)]and soldiers [2.94%(2/68)]. Symptoms including abdominal distension, belching, nausea, vomiting,dyspepsia were common in GERD group compared to control group (P < 0.01). Besides, the laryngitis, pharyngitis and mouth ulcer were common in GERD group compared to control group ( P<0.05). The risk factors of GERD were eating greasy (OR= 1.589) and sweetmeat (OR= 2.413),overeating (OR = 2.053), constipation (OR = 1.650), acridity food (OR = 1.366 ), coffee (OR =1.295), strong tea (OR= 1.362). Conclusions The prevalence of GERD is high in the population of Fujian province, and many factors are closely related to reflux.
